This annual report contains information concerning the gold reserves of Harmony. While this

Exchange Commission Guide 7, it is based on assumptions which may prove to be incorrect. See Item
3. Key Information Risk Factors Harmonys gold reserve figures are estimated based on a number
of assumptions, including assumptions as to mining and recovery factors, future cash costs or
production and the price of gold and may yield less gold under actual production conditions than
currently estimated.

including descriptions of geological formations and mining processes. We have explained some of
these terms in the Glossary of Mining Terms included at the end of this annual report. This
glossary may assist you in understanding these terms.
PRESENTATION OF FINANCIAL INFORMATION
Harmony is a South African company and the majority of its operations are located there.
Accordingly, its books of account are maintained in South African Rand and its annual and interim
financial statements are prepared in accordance with International Financial Reporting Standards,
or IFRS. Harmony also prepares annual financial statements in accordance with generally accepted
accounting principles in the United States, or U.S. GAAP, which are translated into U.S. dollars.
The financial information, other than total cash costs and total cash costs per ounce, included in
this annual report has been prepared in accordance with U.S. GAAP and is presented in US dollars.
Total cash costs and total cash costs per ounce are non-GAAP measures. For further information, see
Item 5. Operating and Financial Review and Prospects Costs Reconciliation of Non-GAAP
Measures. Unless otherwise stated, balance sheet item amounts are translated from Rand to U.S.
dollars at the exchange rate prevailing on the last business day of the period (Rand 7.04 per $1.00
as at June 29, 2007), except for specific items included within shareholders equity that are
converted at the exchange rate prevailing on the date the transaction was entered into, and income
statement item amounts are translated from Rand to US dollars at the average exchange rate for the
period (Rand 7.20 per $1.00 for fiscal 2007).
For the convenience of the reader, certain information in this annual report is presented in
Rand and A$ and has been translated into U.S. dollars. By including convenience currency
translations in this annual report, we are not representing that the Rand and A$ amounts actually
represent the U.S. and Australian dollar amounts, as the case may be, or that these amounts could
be converted at the rates indicated. Unless otherwise stated, the conversion rate for translations
from Rand amounts into U.S. dollar amounts is Rand 7.04 per $1.00, which was the noon buying rate
of the Federal Reserve Bank of New York on June 29, 2007.
FORWARD-LOOKING STATEMENTS
This annual report contains forward-looking statements within the meaning of the United States
Private Securities Litigation Reform Act of 1995 with respect to Harmonys financial condition,
results of operations, business strategies, operating efficiencies, competitive positions, growth
opportunities for existing services, plans and objectives of management, markets for stock and
other matters. In particular, among other statements, certain statements in Item 4. Information on
the Company, Item 5. Operating and Financial Review and Prospects and Item 11. Quantitative and
Qualitative Disclosures About Market Risk are forward-looking in nature. Statements in this annual

harbor provided by Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange

These forward-looking statements, including, among others, those relating to the future
business prospects, revenues and income of Harmony, wherever they may occur in this annual report
and the exhibits to this annual report, are necessarily estimates reflecting the best judgment of
the senior management of Harmony and involve a number of risks and uncertainties that could cause
actual
3
results to differ materially from those suggested by the forward-looking statements. As a
consequence, these forward-looking statements should be considered in light of various important
factors, including those set forth in this annual report. Important factors that could cause actual
results to differ materially from estimates or projections contained in the forward-looking
statements include, without limitation:
|
|
|
overall economic and business conditions in South Africa and elsewhere; |
|
|
|
|
the ability to achieve anticipated efficiencies and other cost savings in connection with past
and future acquisitions; |
|
|
|
|
fluctuations in the market price of gold; |
|
|
|
|
the occurrence of hazards associated with underground and surface gold mining; |

|
|
|
availability, terms and deployment of capital; |
|
|
|
|

Item 3. KEY INFORMATION
SELECTED FINANCIAL DATA
The selected consolidated financial data below should be read in conjunction with, and are
qualified in their entirety by reference to, our consolidated financial statements and the notes
thereto and with Item 5. Operating and Financial Review and Prospects, both included elsewhere in
this annual report. Historical results are not necessarily indicative of results to be expected for
any future period.

SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA
The following selected historical consolidated financial data for the last five fiscal years
has been extracted from the more detailed information and financial statements, including Harmonys
audited consolidated financial statements as of June 30, 2007 and 2006 and for each of the years in
the three years ended June 30, 2007 and the related notes, which appear elsewhere in this annual
report. The historical consolidated financial data at June 30, 2005, 2004 and 2003, and for each of
the years in the two years ended June 30, 2004, has been extracted from Harmonys audited
consolidated financial statements not included in this annual report as adjusted for discontinued
operations and the historical accounting changes described below.
As of June 30, 2007, Harmony has classified the assets and liabilities of certain of its South
African and all of its Australian operations as held for sale. See note 17 of the consolidated
financial statements and Item 4. Information of the Company Business Australasian Operations.
In connection with this determination, Harmony has presented the results of its Australia
operations for all periods as discontinued operations. This is because the operations and cash
flows of the Australian operations will be eliminated from the ongoing operations of Harmony as a
result of the proposed disposal transactions, and the fact that Harmony will not have any
significant continuing involvement in the Australian operations. In contrast, since Harmony
continues to produce and sell gold within South Africa, the results associated with certain of its
South African assets that has been classified as held for sale, continues to be presented within
continuing operations.
During fiscal 2006, Harmony changed its method for accounting for underground development
costs, stripping costs incurred during the production phase of a mine and share-based payments. In
connection with the changes relating to underground development costs and stripping costs incurred
during the production phase of a mine, Harmony early adopted SFAS No. 154, Accounting Changes and
Error Corrections and therefore adjusted its previous financial statements as if the revised
principles had always been used. In connection with the change relating to share-based payments,
Harmony followed the modified retrospective approach permitted by SFAS No. 123(R), Share-based
Payments. Under this method, Harmony also adjusted its previous financial statements based on the
amounts previously recognized under SFAS No. 123 for purposes of pro forma disclosures, without
adjustment.
The financial information, other than total cash costs and total cash costs per ounce,
included in this annual report has been prepared in accordance with U.S. GAAP unless otherwise
noted. Total cash costs and total cash costs per ounce are non-GAAP measures. For further
information, See Item 5. Operating and Financial Review and Prospects Costs Reconciliation of
Non-GAAP Measures.

Total cash costs and total cash costs per ounce are non-GAAP measures. Harmony has calculated
cash costs per ounce by dividing total cash costs, as determined using the guidance provided
by the Gold Institute, by gold ounces sold for all periods presented. The Gold Institute was a
non-profit industry association comprised of leading gold producers, refiners, bullion
suppliers and manufacturers. This institute has now been incorporated into the National Mining
Association. The guidance was first issued in 1996 and was revised in November 1999. Total
cash costs, as defined in the guidance provided by the Gold Institute, include mine production
costs, transport and refinery costs, applicable general and administrative costs, costs
associated with movements in production inventories and ore |

|
|
|
|
stockpiles, ongoing environmental rehabilitation costs as well as transfers to and from deferred
stripping and costs associated with royalties. Ongoing employee termination costs are included,
however, employee termination costs associated with major restructuring and shaft closures are
excluded. Total cash costs have been calculated on a consistent basis for all periods presented
and have been adjusted for the accounting changes associated with underground development costs
and stripping costs incurred during the production phase of the mine. Changes in cash costs per
ounce are affected by operational performance, as well as changes in the currency exchange rate
between the Rand and the U.S. dollar. Because total cash costs and total cash costs per ounce are
non GAAP measures, they should therefore not be considered by investors in isolation or as an
alternative to operating income/(loss) or net income/(loss) or any other U.S. GAAP measure or an
indicator of our performance. In particular depreciation and amortization would be included in a
measure of total costs of producing gold under U.S. GAAP, but it is not included in total cash
costs under the guidance provided by the Gold Institute. While the Gold Institute has provided a
definition for the calculation of total cash costs and total cash costs per ounce, the
calculation of cash costs per ounce may vary from company to company and may not be comparable to
other similarly titled measures of other companies. However, Harmony believes that cash costs per
ounce is a useful indicator to investors and management of a mining companys performance as it
provides (1) an indication of the cash generating capacities of the mining operations, (2) the
trends in cash costs as the companys operations mature, (3) a measure of a companys
performance, by comparison of cash costs per ounce to the spot price of gold and (4) an internal
benchmark of performance to allow for comparison against other companies. For further
information, see Item 5. Operating and Financial Review and Prospects Costs Reconciliation
of non-GAAP measures. |

RISK FACTORS
In addition to the other information included in this annual report and the exhibits, you
should carefully consider the following factors related to Harmonys ordinary shares and ADSs.
There may be additional risks that Harmony does not currently know of or that Harmony currently
deems immaterial based on information currently available to it. Any of these risks could have a
materially adverse effect on Harmonys business, financial condition or results of operations,
resulting in a decline in the trading price of Harmonys ordinary shares or its ADSs. The risks
described below may, in retrospect, turn out not to be complete and therefore may not be the only
risks to which we are exposed. Additional risks and uncertainties not presently known to us or that
we now believe are immaterial, could also adversely affect our businesses, results of operations or
financial condition. The order of presentation of the risk factors below does not indicate the
likelihood of their occurrence or the magnitude or the significance of the individual risks. The
risks described below could occur individually or cumulatively and intensify in case of a
cumulative occurrence.
Risks Relating to Our Business and Our Industry
The profitability of Harmonys operations, and the cash flows generated by those operations, are
affected by changes in the market price of gold, such that a fall in the price of gold below
Harmonys cash cost of production for any sustained period may lead Harmony to experience losses
and curtail or suspend certain operations.
Substantially all of Harmonys revenues come from the sale of gold. Historically, the market
price for gold has fluctuated widely and has been affected by numerous factors over which Harmony
has no control, including:
|
|
|
the demand for gold for industrial uses and for use in jewelry; |
|
|
|
|
international or regional political and economic trends; |
|
|
|
|
the strength of the U.S. dollar and of other currencies; |
|
|
|
|
financial market expectations regarding the rate of inflation; |
|
|
|
|
interest rates; |
|
|
|
|
speculative activities; |
|
|
|
|
actual or expected purchases and sales of gold bullion held by central banks or other
large gold bullion holders or dealers; |
|
|
|
|
forward sales by other gold producers; and |
|
|
|
|
the production and cost levels for gold in major gold-producing nations, such as South
Africa, United States, Australia and China. |
In addition, the current demand for and supply of gold affects the price of gold, but not
necessarily in the same manner as current demand and supply affect the prices of other commodities.
Historically, gold has retained its value in relative terms against basic goods in times of
inflation and monetary crisis. As a result, central banks, financial institutions and individuals
hold large amounts of gold as a store of value and production in any given year constitutes a very
small portion of the total potential supply of gold. Since the potential supply of gold is large,
relative to mine production in any given year, normal variations in current production will not
necessarily have a significant effect on the supply of gold or its price.
The volatility of gold prices is illustrated in the following table, which shows the annual
high, low and average of the afternoon London Bullion Market fixing price of gold in U.S. dollars
for the past ten calendar years:

On November 28, 2007, the afternoon fixing price of gold on the London Bullion Market was $805
per ounce.
While the aggregate effect of these factors is impossible for Harmony to predict, if gold
prices should fall below Harmonys cash cost of production and remain at such levels for any
sustained period, Harmony may experience losses and may be forced to curtail or suspend some or all
of its operations. In addition, Harmony would also have to assess the economic impact of low gold
prices on its ability to recover any losses it may incur during that period and on its ability to
maintain adequate reserves. Harmonys average cash cost per ounce of gold sold was $486 in fiscal
2007, $436 in fiscal 2006 and $378 in fiscal 2005.
Due to the fact that the majority of Harmonys production costs are incurred in Rand and that gold
is sold in U.S. dollars, Harmonys financial condition could be materially harmed by an
appreciation in the value of the Rand against the U.S. dollar.
Gold is sold throughout the world in U.S. dollars, but the majority of Harmonys operating
costs are incurred in Rand. As a result, any significant and sustained appreciation of Rand against
the U.S. dollar will serve materially to reduce Harmonys Rand revenues and overall net income.
Harmony is significantly influenced by the fluctuations in the Rand/U.S. dollar exchange.
While the Rand has both depreciated and appreciated against the U.S. dollar in the past year, these
fluctuations have an impact on Harmonys operating environment.
Harmonys gold reserve figures are estimated based on a number of assumptions, including
assumptions as to mining and recovery factors, future cash costs of production and the price of
gold and may yield less gold under actual production conditions than currently estimated.
The ore reserve estimates contained in this annual report are estimates of the mill delivered
quantity and grade of gold in Harmonys deposits and stockpiles. They represent the amount of gold
which Harmony believes can be mined, processed and sold at prices sufficient to recover its
estimated future cash costs of production, remaining investment and anticipated additional capital
expenditures. Harmonys ore reserves are estimated based upon a number of factors, which have been
stated in accordance with SEC Industry Guide 7. As Harmonys ore reserve estimates are calculated
based on estimates of future cash costs, (which in some cases are assumed to decrease
significantly), future gold prices and, because of the fact that Harmonys gold sales are primarily
in U.S. dollars and Harmony incurs most of its cash costs in Rand, the exchange rate which is not
under our control, between the Rand and the U.S. dollar and, in the case of Harmonys Australian
operations, between the Rand and the Australian dollar, significantly impacts this ore reserve
estimate. As a result, the reserve estimates contained in this annual report should not be
interpreted as assurances of the economic life of Harmonys gold deposits or the profitability of
its future operations.
Since ore reserves are only estimates that Harmony makes based on the above factors, Harmony
may in the future need to revise these estimates. In particular, if Harmonys cash costs of
operating and production increase or do not decrease as assumed (whether in U.S. dollar terms, Rand
terms, Australian dollar terms, or in relative terms due to appreciation of the Rand or the
Australian dollar against the U.S. dollar) or the gold price decreases, the recovery of a portion
of Harmonys ore reserves may become uneconomical. This will force Harmony to lower its estimated
reserves.
To maintain gold production beyond the expected lives of Harmonys existing mines or to increase
production materially above projected levels, Harmony will need to access additional reserves
through exploration or discovery.
Harmonys operations have limited proven and probable reserves and exploration and discovery
is necessary to maintain current gold production levels at these operations. Exploration for gold
and other precious metals is speculative in nature, is frequently unsuccessful and involves many
risks, including risks related to:
11
|
|
|
identifying the metallurgical properties of orebodies; |
|
|
|
|
estimating the economic feasibility of mining orebodies; |
|
|
|
|
developing appropriate metallurgical processes; |
|
|
|
|
obtaining necessary governmental permits; and |
|
|
|
|
constructing mining and processing facilities at any site chosen for mining. |
Harmonys exploration efforts might not result in the discovery of mineralization and any
mineralization discovered might not result in an increase in Harmonys proven and probable
reserves. To access additional reserves, Harmony will need to successfully complete development
projects, including extending existing mines and, possibly, developing new mines. Development
projects would also be necessary to access any new mineralization discovered through our
exploration activities around the world. Harmony typically uses feasibility studies to determine
whether or not to undertake significant development projects. Feasibility studies include estimates
of expected or anticipated economic returns, which are based on assumptions about:
|
|
|
future gold and other metal prices; |
|
|
|
|
anticipated tonnage, grades and metallurgical characteristics of ore to be mined and
processed; |
|
|
|
|
anticipated recovery rates of gold and other metals from the ore, and |
|
|
|
|
anticipated total costs of the project, including capital expenditure and cash costs. |
Actual cash costs of production, production and economic returns may differ significantly from
those anticipated by Harmonys feasibility studies for new development projects.
It can take a number of years from initial feasibility studies until development is completed
and during that time, the economic feasibility of production may change. In addition, there are a
number of uncertainties inherent in the development and construction of an extension to an existing
mine or any new mine, including:
|
|
|
the availability and timing of necessary environmental and governmental permits; |
|
|
|
|
the timing and cost necessary to construct mining and processing facilities, which can be
considerable; |
|
|
|
|
the availability and cost of skilled labor, power, water and other materials; |
|
|
|
|
the accessibility of transportation and other infrastructure, particularly in remote
locations; |
|
|
|
|
the availability and cost of smelting and refining arrangements; and |
|
|
|
|
the availability of funds to finance construction and development activities. |
Harmony has addressed growth through the recent expansion of its exploration activities.
Harmony currently maintains a range of focused exploration programs, concentrating on areas not too
distant from its operational mines, as well as a number of prospective known gold mineralized
regions around the world. During fiscal 2007 and for fiscal 2006, the bulk of exploration
expenditure was allocated to activities in Australia, Papua New Guinea (PNG) and South Africa.
However, there is no assurance that any future development projects will extend the life of
Harmonys existing mining operations or result in any new commercial mining operations.
As we currently do not enter into forward sales, derivatives or hedging arrangements with respect
to our future gold production, we are exposed to the impact of any significant decrease in the
gold price.
As a general rule, we sell our gold at market prices. Currently, we generally do not enter
into forward sales, derivatives or hedging arrangements to establish a price in advance for the
sale of our future gold production, although we may do so in the future. As a
12
result, we may realize the positive impact of any short term increase in the gold price, but
are not protected against decreases in the gold price, and if the gold price decreases
significantly, our revenues may be materially adversely affected.
Harmony may experience problems in identifying, financing and managing new acquisitions and
integrating them with its existing operations.
Acquiring new gold mining operations involves a number of risks including:
|
|
|
Harmonys ability to identify appropriate acquisition candidates or negotiate
acquisitions on favorable terms; |
|
|
|
|
obtaining the financing necessary to complete future acquisitions; |
|
|
|
|
difficulties in assimilating the operations of the acquired business; |
|
|
|
|
difficulties in maintaining the financial and strategic focus of Harmony while
integrating the acquired business; |
|
|
|
|
problems in implementing uniform standards, controls, procedures and policies; |
|
|
|
|
increasing pressures on existing management to oversee a rapidly expanding company; and |
|
|
|
|
to the extent Harmony acquires mining operations outside South Africa or Australia
encountering difficulties relating to operating in countries in which Harmony has not
previously operated. |
Our ability to make successful acquisitions and any difficulties or time delays in achieving
successful integration of any of such acquisitions could have a material adverse effect on
Harmonys business, operating results, financial condition and share price.
Due to the nature of mining and the type of gold mines it operates, Harmony faces a material risk
of liability, delays and increased cash costs of production from environmental and industrial
accidents and pollution.
The business of gold mining by its nature involves significant risks and hazards, including
environmental hazards and industrial accidents. In particular, hazards associated with underground
mining include:
|
|
|
rockbursts; |
|
|
|
|
seismic events; |
|
|
|
|
underground fires; |
|
|
|
|
cave-ins or falls of ground; |
|
|
|
|
discharges of gases and toxic chemicals; |
|
|
|
|
release of radioactive hazards; |
|
|
|
|
flooding; |
|
|
|
|
pillar mining |
|
|
|
|
accidents; and |
|
|
|
|
other conditions resulting from drilling, blasting and the removal and processing of
material from a deep-level mine. |
Hazards associated with open cast mining (also known as open pit mining) include:
|
|
|
flooding of the open pit; |
13
|
|
|
collapse of the open pit walls; |
|
|
|
|
accidents associated with the operation of large open pit mining and rock transportation
equipment; and |
|
|
|
|
accidents associated with the preparation and ignition of large scale open pit blasting
operations. |
Hazards associated with waste rock mining include:
|
|
|
accidents associated with operating a waste dump and rock transportation; |
|
|
|
|
pillar mining; and |
|
|
|
|
production disruptions due to weather. |
Harmony is at risk of experiencing any and all of these environmental or other industrial
hazards. The occurrence of any of these hazards could delay production, increase cash costs and
result in financial liability to Harmony.
The nature of Harmonys mining operations presents safety risks.
The environmental and industrial risks identified above also present safety risks for
Harmonys operations and its employees and can lead to the suspension and potential closure of
operations for indeterminate periods. For example, in October 2007, an incident occurred at the
Elandsrand operation involving a compressed pipe column which broke off below the shaft surface
bank and fell to the bottom of the men and material shaft, causing extensive damage to the
shaft stee work and electrical cables. The incident resulted in 3,000 workers being stranded
underground for more than 30 hours. Mining operations were temporarily suspended for 44 days to
allow for repairs to be conducted in the shaft. These and other safety risks, even in situations
where no injuries are experienced, can have a material adverse effect on the companys operations
and production.
Harmonys insurance coverage may prove inadequate to satisfy future claims against it.
Harmony has third-party liability coverage for most potential liabilities, including
environmental liabilities. While Harmony believes that its current insurance coverage for the
hazards described above is adequate and consistent with industry practice, Harmony may become
subject to liability for pollution (excluding sudden and accidental pollution) or other hazards
against which it has not insured or cannot insure, including those in respect of past mining
activities. Further, Harmony maintains and intends to continue to maintain, property and liability
insurance consistent with industry practice, but such insurance contains exclusions and limitations
on coverage. In addition, there can be no assurance that insurance will continue to be available at
economically acceptable premiums. As a result, in the future Harmonys insurance coverage may not
cover the extent of claims against it for environmental or industrial accidents or pollution.
Harmonys operations may be negatively impacted by inflation.
Harmonys operations have been materially affected by inflation in recent years. Even though
the inflation rate has decreased over the last three years, working costs and especially wages have
increased considerably over the past three years resulting in significant cost pressures on the
mining industry. Harmonys profits and financial condition could also be affected adversely in the
absence of a concurrent devaluation of the Rand and an increase in the price of gold.
The socio-economic framework in the regions in which we operate may have an adverse effect on
Harmonys operations and profits.
Harmony has operations in South Africa, Australia and PNG. As a result, changes or instability
to the economic or political environment in any of these countries or in neighboring countries
could affect an investment in Harmony. It is difficult to predict the future political, social and
economic direction in these countries, or any other country in which we operate, and the impact
government decisions may have on our business.
14
Actual and potential shortages of production inputs may have an adverse effect on Harmonys
operations and profits.
Harmonys results of operations may be affected by the availability and pricing of raw
materials and other essential production inputs. The price of raw materials may be substantially
affected by changes in global supply and demand, along with weather conditions, governmental
controls and other factors. A sustained interruption on the supply of any of these materials would
require Harmony to find substitute suppliers acceptable to it and could require it to pay higher
prices for such materials. Any significant increase in the prices of these materials will increase
Harmonys operating costs and affect production considerations.
Harmonys financial flexibility could be materially constrained by exchange control regulations as
imposed by the South African Reserve Bank (SARB).
South Africas exchange control regulations provide for restrictions on exporting capital from
South Africa. As a result, Harmonys ability to raise and deploy capital outside South Africa is
restricted. In particular, Harmony:
|
|
|
is generally not permitted to export capital from South Africa, to hold foreign currency
or incur indebtedness denominated in foreign currencies without the approval of the South
African exchange control authorities; |
|
|
|
|
is generally not permitted to acquire an interest in a foreign venture without the
approval of the South African exchange control authorities and first having complied with
the investment criteria of the South African exchange control authorities; |
|
|
|
|
is generally required to repatriate to South Africa profits of foreign operations; and |
|
|
|
|
is limited in its ability to utilize profits of one foreign business to finance
operations of a different foreign business. |
These restrictions could hinder Harmonys normal corporate functioning, including its ability
to make foreign investments and procure foreign currency denominated financings in the future.
While exchange controls have been relaxed in recent years, it is difficult to predict whether or
how the South African Government will further relax the exchange control regulations in the future.
Since 1995, certain exchange controls in South Africa have been relaxed. The extent to which
the South African Government may further relax such exchange controls cannot be predicted with
certainty, although the Government has committed itself to a gradual approach of relaxation.
Further relaxation, or abolition of exchange controls may precipitate a change in the capital flows
to and from South Africa. In the event of the immediate abolition of exchange control there may be
a sudden withdrawal of Rand from the South African market by investors. Because South Africa has a
fully floating exchange rate and a flexible interest rate policy, this would result in a rapid
depreciation of the Rand exchange rate which would serve to stem the withdrawal and would also
result in an increase in interest rates due to the depreciation of the Rand.
Since Harmonys South African labor force has substantial trade union participation, Harmony faces
the risk of disruption from labor disputes and new South African labor laws.
Despite a history of positive and constructive engagement with labor unions, there are periods
during which the various stakeholders are unable to agree on dispute resolution processes.
Disruptive activities on the part of labor, which normally differ in intensity, then become
unavoidable. Due to the high level of union membership among Harmonys employees, Harmony is at
risk of having, and did experience in both fiscal 2006 and 2005 for example, production stoppages
for indefinite periods due to strikes and other disputes. The National Union of Mineworkers (NUM)
is a major union representing more than 75% of the employees in South Africa. Harmony is currently
negotiating a compromise with the NUM to develop improved safety standards and performance by all
stakeholders and to avoid antagonistic attitudes developing around safety issues. Failure to reach
agreement on any disputes with NUM could have an adverse affect on our operations. Significant
labor disruptions have affected our operations and financial condition before and we are not able
to predict whether or not we will experience significant labor disputes in the future.
South African employment law sets out minimum terms and conditions of employment for
employees. Though these minimum terms and conditions may be improved upon by agreements concluded
between Harmony and the trade unions, the prescribed minimum terms and conditions forms the
benchmark for all employment contracts.
South African employment law regulates the working hours of employees and provides for
severance payment equivalent to one week for each completed year of service insofar as an
employees employment is terminated due to operational requirements. Agreements between Harmony and
the trade unions may vary the working hours and the payments employees are entitled to where their
employment is terminated due to operational requirements.
15
South African employment law allows an employer and trade unions to apply for exemption from
certain sections of employment legislation. The Minister of Labor granted certain exemptions to
gold and colliery members of the South African Chamber of Mines. These determinations by the
Minister of Labor are designed to take into account the practical circumstances and arrangements
which prevail in the gold and coal mining industries and not catered for in legislation. A number
of the variations cater for the employees preferences in relation to working hours.
Harmony is required to submit a report in terms of South African employment law detailing the
progress made towards achieving employment equity in the workplace. In the event this report is not
submitted, Harmony could attract substantial penalties.
Development in South African employment law may increase our cash costs of production or alter
our relationship with our employees and trade unions, which may have an adverse effect on our
business, operating results and financial condition.
Harmony may suffer adverse consequences as a result of its reliance on outside contractors to
conduct its operations.
A portion of Harmonys operations are currently conducted by outside contractors. As a result,
Harmonys operations are subject to a number of risks, some of which are outside Harmonys control,
including:
|
|
|
negotiating agreements with contractors on acceptable terms; |
|
|
|
|
the inability to replace a contractor and its operating equipment in the event that
either party terminates the agreement; |
|
|
|
|
reduced control over those aspects of operations which are the responsibility of the
contractor; |
|
|
|
|
failure of a contractor to perform under its agreement with Harmony; |
|
|
|
|
interruption of operations in the event that a contractor ceases its business due to
insolvency or other unforeseen events; |
|
|
|
|
failure of a contractor to comply with applicable legal and regulatory requirements, to
the extent it is responsible for such compliance; and |
|
|
|
|
problems of a contractor with managing its workforce, labor unrest or other employment
issues. |
In addition, Harmony may incur liability to third parties as a result of the actions of its
contractors. The occurrence of one or more of these risks could have a material adverse effect on
Harmonys business, results of operations and financial condition. See Directors, Senior
Management and EmployeesEmployees.
HIV/AIDS poses risks to Harmony in terms of productivity and costs.
The incidence of HIV/AIDS in South Africa and PNG, which is forecast to increase over the next
decade, poses risks to Harmony in terms of potentially reduced productivity and increased medical
and other costs. Harmony expects that if a significant increase in the incidence of HIV/AIDS
infection and HIV/ AIDS-related diseases among the workforce over the next several years occurs
then this may have an adverse impact on Harmonys operations, projects and financial status. This
expectation, however, is based on assumptions about, among other things, infection rates and
treatment costs which are subject to material risks and uncertainties beyond Harmonys control. As
a result, actual results may differ from the current estimates.
The cost of occupational healthcare services may increase in the future.
Harmonys operations in South Africa are subject to health and safety regulations which could
impose significant costs and burdens. The present Mine Health and Safety Act 29 of 1996, or the
Mine Health and Safety Act, which imposes various duties on Harmony at its mines, and grants the
authorities broad powers to, among other things, close unsafe mines and order corrective action
relating to health and safety matters.
The Occupational Diseases in Mines and Works Act 78 of 1973, or the Occupational Diseases Act,
governs the payment of compensation and medical costs related to certain illnesses contracted by
persons employed in mines or at sites where activities ancillary to mining are conducted.
Occupational healthcare services are available to Harmonys employees from its existing healthcare
facilities in South Africa. There is a risk that the cost of providing such services could increase
in future depending on changes in the
16
nature of underlying legislation and the profile of Harmonys employees. This increased cost,
should it transpire, is currently indeterminate. Harmony has embarked on a number of initiatives
focused on improving the quality of life of Harmonys workforce, although there can be no guarantee
that such initiatives will not be adversely affected by increased costs.
Laws governing mineral rights affect our business.
Harmony is governed by the South African Mineral and Petroleum Resources Development Act 2002
(MPRDA). See RegulationHealth and Safety MattersSouth Africa for a description of the
principal objectives set out in the MPRDA.
Under the MPRDA, tenure over established mining operations is secured for up to 30 years (and
renewable for periods not exceeding 30 years each thereafter), provided that mining companies apply
for new order mining rights over existing operations within five years of May 1, 2004 or before the
existing right expires, whichever is the earlier date and fulfill requirements specified in the
MPRDA and the Broad-Based Socio-Economic Empowerment Charter for the South African mining industry
(Mining Charter).
The Mining Charter was signed by government and stakeholders in October 2002 and contains
principles relating to the transfer, over a 10-year period, of 26% of South Africas mining assets
(as equity or attributable units of production) to historically disadvantaged South Africans, as
defined in the Mining Charter (HDSA). An interim target of 15% HDSA participation over 5 years
has also been set and to this end, the South African mining industry has committed to securing
financing to fund participation by HDSAs in an amount of R100.0 billion within the first five years
of the Mining Charters tenure. The Mining Charter provides for the review of the participation
process after five years to determine what further steps, if any, are needed to achieve the 26%
target participation. In order to measure progress in meeting the requirements of the Mining
Charter, companies are required to complete a Scorecard, in which the levels of compliance with
the objectives of the Mining Charter can be ticked off after 5 and 10 years respectively. The
Mining Charter and Scorecard require programs for black economic empowerment and the promotion of
value-added production, such as jewelry-making and other gold fabrication, in South Africa. In
particular, targets are set out for broad-based black economic empowerment in the areas of human
resources and skills development; employment equity; procurement and beneficiation. In addition,
the Mining Charter addresses socio-economic issues, such as migrant labor; mine community and rural
development, and housing and living conditions.
Currently, the South African government has given its assurance that the Mining Charter will
take precedence over the more recently promulgated Black Economic Empowerment Act, 2003 and
particularly the Codes of Good Practice published thereunder, which are of general application to
the South African economy. It is therefore envisaged that the Mining Charter will remain relevant
to securing the conversion of mineral rights.
Harmony actively carries out mining and exploration activities in all of its material mineral
rights areas. All of Harmonys operations have been granted their mining licenses and execution of
the licences will be finalised by January 2008. We will be eligible to apply for new licenses over
existing operations, provided that we comply with the Mining Charter. We have taken steps to comply
with the expected provisions of the Mining Charter, such as promoting value-added production,
exploring black empowerment initiatives and increasing worker participation. Failure to comply
with the conditions of the mining licences could have a material adverse effect on our operations
and financial condition.
The MPRDA also makes reference to royalties payable to the South African state in terms of the
envisaged Mining and Petroleum Royalty Act which has not yet been finalized. However, a Bill, known
as the Royalty Bill, has been made available for public comment. The introduction of the Mining and
Petroleum Royalty Act will have an adverse impact on the profits generated by Harmonys operations
in South Africa. According to the terms of the draft regulations, royalties will only be payable
from 2009.
In Australia, most mineral rights belong to the government, and mining companies pay royalties
to the government based on production. There are, however, limited areas where the government
granted freehold estates without reserving mineral rights. Harmonys subsidiary, New Hampton, has
freehold ownership of its Jubilee mining areas, but the other mineral rights in Harmonys
Australian operations are subject to royalty payments. In addition, current Australian law
generally requires landowner title approval to be obtained before a mining license can be granted
and mining operations can commence. New Hampton and Hill 50 have approved mining leases for most of
their reserves, including all reserves that are currently being mined. Should New Hampton or Hill
50 desire to expand operations into additional areas under exploration, these operations would need
to convert the relevant exploration licenses prior to the start of mining, and that process could
require landowner title approval. There can be no assurance that any approval would be received.
Please also see Regulation for further information.
In PNG, Harmonys mining operations will be subject to royalty payments to the government of
PNG. Should we desire to expand any of our initiatives in PNG operations into additional areas
under exploration, these operations would need to convert the relevant
17
exploration licenses prior to the start of mining, and that process could require landowner
title approval. There can be no assurance that any approval would be received. Please also see
Regulation for further information.
Harmony is subject to extensive environmental regulations.
As a gold mining company, Harmony is subject to extensive environmental regulation. Harmony
has experienced and expects to continue to experience increased cash costs of production arising
from compliance with South African and Australian environmental laws and regulations. The MPRDA,
certain other environmental legislation and the administrative policies of the South African
government regulate the impact of Harmonys prospecting and mining operations on the environment.
Pursuant to these regulations, upon the suspension, cancellation, termination or lapsing of a
prospecting permit or mining authorization in South Africa, Harmony will remain liable for
compliance with the provisions of the MPRDA, including any rehabilitation obligations. This
liability will continue until such time as the South African Department of Minerals and Energy
certifies that Harmony has complied with such provisions.
In the future, Harmony may incur significant costs associated with complying with more
stringent requirements imposed under new legislation and regulations. This may include the need to
increase and accelerate expenditure on environmental rehabilitation and alter provisions for this
expenditure, which could have a material adverse effect on Harmonys results and financial
condition. Harmony may also face increased environmental costs resulting from other mines in the
vicinity of Harmonys mines failing to meet their obligations with regard to the pumping or
treatment of water.
The South African government has reviewed requirements imposed upon mining companies to ensure
environmental restitution. For example, following the introduction of an environmental rights
clause in South Africas constitution, a number of environmental legislative reform processes have
been initiated. Legislation passed as a result of these initiatives has tended to be materially
more onerous than laws previously applied in South Africa. Examples of such legislation include the
MPRDA, the South African National Nuclear Regulator Act 1999, the South African National Water Act
of 1998 and the South African National Environmental Management Act 1998, which include stringent
polluter-pays provisions. The adoption of these or additional or more comprehensive and stringent
requirements, in particular with regard to the management of hazardous wastes, the pollution of
ground and ground water systems and the duty to rehabilitate closed mines, may result in additional
costs and liabilities.
Harmonys Australian and PNG operations are also subject to various laws and regulations
relating to the protection of the environment, which are similar in scope to those of South Africa.
Harmony may not pay cash dividends to its shareholders in the near future.
While it is the intention of Harmony to declare and pay cash dividends, it is its policy to
only do so if profits and funds are available for that purpose. Whether or not funds are available
depends on a variety of factors, including the amount of cash available and on capital expenditures
and other cash requirements existing at that time. Under South African law, cash dividends may only
be paid out of the retained or current profits of Harmony. We did not declare a cash dividend in
fiscal 2007, 2006 or 2005 and we cannot guarantee that cash dividends will be paid in the future.
Non-South African shareholders of Harmony face additional investment risk from currency exchange
rate fluctuations since any dividends will be paid in Rand.
Dividends or distributions with respect to Harmonys ordinary shares have historically been
paid in Rand. The U.S. dollar equivalent of any dividends or distributions with respect to
Harmonys ordinary shares would be adversely affected by potential future decreases in the value of
the Rand against the US dollar.
Investors in the United States may have difficulty bringing actions, and enforcing judgments,
against Harmony, its directors and its executive officers based on the civil liabilities
provisions of the federal securities laws or other laws of the United States or any state thereof.
Harmony is incorporated in South Africa. All of Harmonys directors and executive officers
(and certain experts named herein) reside outside of the United States. Substantially all of the
assets of these persons and substantially all of the assets of Harmony are located outside the
United States. As a result, it may not be possible for investors to enforce against these persons
or Harmony a judgment obtained in a United States court predicated upon the civil liability
provisions of the federal securities or other laws of the
18
Unites States or any state thereof. A foreign judgment is not directly enforceable in South
Africa, but constitutes a cause of action which will be enforced by South African courts provided
that:
|
|
|
the court that pronounced the judgment had jurisdiction to entertain the case according
to the principles recognized by South African law with reference to the jurisdiction of
foreign courts; |
|
|
|
|
the judgment is final and conclusive; |
|
|
|
|
the judgment has not lapsed; |
|
|
|
|
the recognition and enforcement of the judgment by South African courts would not be
contrary to public policy, including observance of the rules of natural justice which
require that the documents initiating the United States proceeding were properly served on
the defendant and that the defendant was given the right to be heard and represented by
counsel in a free and fair trial before an impartial tribunal; |
|
|
|
|
the judgment does not involve the enforcement of a penal or revenue law; and |
|
|
|
|
the enforcement of the judgment is not otherwise precluded by the provisions of the
Protection of Business Act 99 of 1978, as amended, of the Republic of South Africa. |
Compliance with new and changing corporate governance and public disclosure requirements adds
uncertainty to our compliance policies and increases our costs of compliance.
Laws, regulations and standards relating to accounting, corporate governance and public
disclosure, new SEC regulations and other listing regulations applicable to us are subject to
change and can create uncertainty for companies like Harmony. New or changed laws, regulations and
standards could lack specificity or be subject to varying interpretations. Their application in
practice may evolve over time as new guidance is provided by regulatory and governing bodies. This
could result in continuing uncertainty regarding compliance matters and higher costs of compliance
as a result of ongoing revisions to such governance standards.
Beginning this fiscal year ending June 30, 2007, pursuant to Section 404 of the Sarbanes-Oxley
Act of 2002, Harmony is required to furnish a report by its management on its internal control over
financial reporting. The report in this annual report contains, among other matters, an assessment
of the effectiveness of Harmonys internal control over financial reporting as of the end of the
fiscal year, including a statement as to whether or not its internal controls over financial
reporting are effective. Harmony is required to have its independent auditors publicly disclose
their conclusions regarding the evaluation.
During fiscal 2007, we experienced a breakdown in internal controls over financial reporting
related in part to the implementation of a new Enterprise Resource Planning (ERP) system. Certain
month-end controls relating to accounts payable, cash and bank deposits as well as inventory could
not be performed during the fiscal year due to difficulties encountered with the implementation of
the system which led to material adjustments being required in our financial statements.
Accordingly, we have identified certain material weaknesses in our internal controls over financial
reporting, in particular relating to the information technology control environment and the
financial reporting closing process which have also negatively impacted the report issued by our
auditors regarding our internal controls over financial reporting. See Item 15. Disclosure
Controls and Procedures.
We are committed to maintaining high standards of corporate governance and public disclosure,
and our efforts to comply with evolving laws, regulations and standards in this regard have
resulted in, and are likely to continue to result in, increased general and administrative
expenses.
Investors may face liquidity risk in trading Harmonys ordinary shares on the JSE Limited.
The primary listing of our ordinary shares is on the JSE Limited. Historically, trading
volumes and liquidity of shares listed on the JSE have been low in comparison with other major
markets. The ability of a holder to sell a substantial number of Harmonys ordinary shares on the
JSE in a timely manner, especially in a large block trade, may be restricted by this limited
liquidity. See The Offer and ListingThe Securities Exchange in South Africa.
19
Because Harmony has a significant number of outstanding share options and convertible debt
instruments, Harmonys ordinary shares are subject to dilution.
Harmony has employee share option schemes as well as other share schemes. The employee share
option schemes came into effect in 1994, 2001 and 2003 respectively and a new share scheme was
introduced in 2006. Harmonys board has authorized up to 14% of the issued share capital to be
used for these plans. Additionally, the company has convertible uncollaterized fixed rate bonds in
the amount of $237 million which are due on May 21, 2009. These bonds may be converted into equity
at the option of the bondholder at any time from July 1, 2004 and May 15, 2009 at a specific
conversion price based on the outstanding principal amount divided by the conversion price in
effect on that date. As a result, shareholders equity interests in Harmony are subject to dilution
to the extent of the future exercises of the options, through share schemes and convertible debt
instruments.
Item 4. INFORMATION ON THE COMPANY
BUSINESS
History and Development
Harmony conducts underground and surface gold mining and related activities, including
exploration, processing and smelting. We are currently the third largest producer of gold in South
Africa, producing approximately 19.7% of the countrys annual gold output, and the fifth largest
gold producer in the world with operations and projects in South Africa, Australia and PNG.
Harmonys gold sales have increased from 650,312 ounces of gold in fiscal 1995 to approximately
2.3 million ounces of gold in fiscal 2007. As at June 30, 2007, our mining operations reported
total proven and probable reserves of 53.67 million ounces, primarily from South African sources.
In fiscal 2007, we processed approximately 22.8 million tons of ore.
In fiscal 2007, approximately 90% of Harmonys gold production took place in South Africa and
approximately 10% in Australia. In fiscal 2007, approximately 95% of Harmonys South African gold
came from underground mines, approximately 3% came from its Kalgold opencast operation, and
approximately 2% was produced from the treatment of surface sand and slime operations. For more
detailed geographical information about Harmonys activities, see Item 4. Information on the
Company Business Harmonys Mining Operations Overview and the notes to the consolidated
financial statements included in this annual report. Mining is a highly regulated industry, and we
operate under a variety of statutes and regulations. For more detailed information about these
statutes and regulations, see Item 4. Information on the Company Regulation and Item 10.
Additional Information Memorandum and Articles of Association.
We also have exploration and evaluation programs focused on parts of Australia, PNG and West
Africa. Exploration and evaluation of Africa is handled through the South African office, while
Australian and PNG exploration and evaluation opportunities are handled through the Australian
office.
Harmony was incorporated and registered as a public company in South Africa on August 25, 1950
(under registration number 1950/038232/06). Harmony poured its first gold on 11 September 1954. In
the early seventies it was merged with the Anglovaal mines, Merriespruit and Virginia, forming
Harmony Gold Mining Company Limited. In 1995, Harmony was rejuvenated. It expanded from a single
lease-bound mining operation into an independent, world-class gold producer. We acquired
additional mineral rights in the Free State, Mpumalanga, Gauteng and North West provinces in South
Africa when we acquired Lydex in 1997, Evander in 1998, Kalgold in 1999, Randfontein in 2000,
ARMgold in 2003 and Avgold in 2004. In building our Australian portfolio, we acquired Hill 50 and
New Hampton in Western Australia in 2001 and 2002, respectively, and started our exploration
portfolio in PNG with projects in the Morobe province originally through our acquisition of Abelle
in 2003. In 2007 we became a member of the World Gold Council, the association representing the
wider marketing and public policy issues of many of the worlds biggest gold mining companies.
Our principal executive offices are located at Randfontein Office Park, Corner of Main Reef
Road and Ward Avenue, Randfontein, 1760, South Africa and the telephone number at this location is
+27-11-411-2000.
South African Operations
In South Africa, Harmony operates a total of 22 shafts, 1 project shaft, 1 open cast mine, and
9 processing plants which are located in all of the currently known goldfields in the Witwatersrand
basin of South Africa as well as the Green Stone belt. These operations produced 2.1 million ounces
in fiscal 2007, and South Africa represented approximately 91% (or 48.95 million ounces) of
Harmonys total proven and probable reserves. The deep level gold mines located in this basin
include those in the Free State province, the Evander gold mine in Mpumalanga province, the
Randfontein and Elandskraal mines in the West Rand goldfields in Gauteng province
20
and the Orkney and Kalgold operations in the North West province. In September 2007, Harmony
announced that it has signed formal agreements with Pamodzi Gold Limited (Pamodzi Gold) regarding
the sale of Orkney shafts. See Item 8 Recent Developments.
Ore from the shafts and surface material are treated at 9 metallurgical plants in South Africa
(4 in the Free State, 1 in Carltonville, 2 in Evander, 2 in Randfontein and 1 near Mafikeng). There
are 2 plants on care and maintenance which can be restarted if additional processing capacity is
required (Joel plant and St. Helena plant).
We manage and evaluate our operations on a shaft-by-shaft basis. The South African underground
operations are treated as three separate reporting segments for management and reporting purposes.
We have found this system to be very effective as, among other things, it allows for different
management styles and capital allocations.
These 3 segments are:
|
|
|
the Quality Assets, which typically have a larger reserve base and hence a longer mine
life. These form the core of our operations; |
|
|
|
|
the Leveraged Assets are those that have a large resource base and provide significant
upside in the event of a rising gold price; and |
|
|
|
|
the Growth Assets, which comprise the expansion projects and new mines currently under
development in South Africa. |
There are also a number of surface operations around existing mines, which treat historic sand
dumps, rock dumps and tailings dams next to our underground operations in addition to the Kalgold
open-cast mine:

Australasian Operations
Harmonys interests in Australasia are located in Australia and PNG and represent 9% (or 4.72
million ounces) of Harmonys total proven and probable reserves.
Harmonys interests in Australia consist of two operating centers, consisting of both
underground and open pit mines located at Mt. Magnet and South Kalgoorlie in Western Australia.
Underground and surface mining is conducted at each of our Australian operations, with underground
access through two declines at Mt. Magnet and one decline at South Kalgoorlie and surface access
through open pits (mining at the decline at South Kalgoorlie ceased at the end of the financial
year). These operations produced 224,799 ounces in fiscal 2007 (2006: 231,461 ounces) and
represented approximately 1% (or 0.46 million ounces) of Harmonys total proven and probable
reserves. Ore from the shafts and surface material are treated at two metallurgical plants in
Australia (one at Mt. Magnet and one at South Kalgoorlie).
21
Harmony has classified the Western Australia operations as available for sale. In July 2007,
Harmony entered into an agreement with Dioro Exploration NL (Dioro) to acquire Harmonys South
Kalgoorlie assets in Western Australia. The total purchase price is
A$45 million (US$38.2 million), which consists
of a cash component and a share component. The share component entails the issuance of 160 million
Dioro shares, or shares to the value of A$20 million
($17 million), and a cash component of A$25 million (US$21.2 million). The
transaction is subject to various conditions precedent, including a minimum capital raising by
Dioro of A$35 million (US$29.8 million) by the completion date. The completion of the agreement is subject to
regulatory approvals.
In November 2007, Harmony announced that it has signed a letter of intent with the
Australian-based junior miner Monarch Gold Mining Company for the sale of its Mt Magnet operations
for A$65 million (US$57.2 million). The Mt Magnet asset package, which includes Hill 50, Great Fingall, St George,
Star and Big Bell mines, comprises a resource inventory of 2.7Moz of gold, tenements covering
approximately 62,000 hectares and 166 exploration licence blocks, along with a 2.7Mt a year
capacity plant. The offer is made up of a combination of
A$30 million cash (US$26.4 million), A$20 million
(US$17.6 million) in shares
and A$15 million (US$13.2 million) in convertible notes. The transaction will require a capital raising by Monarch
on the Toronto Stock Exchange by the completion date.
In PNG, Harmony owns development and exploration prospects in the Morobe Province. Harmony is in
the process of building a new mine in Hidden Valley which is expected to commence production in the
March 2009 quarter. In addition, Harmony has completed its Golpu stand alone pre-feasibility study
(PFS) during the June 2007 quarter, on time and within budget. The study has identified a
technically and economically viable project plan, with the highlight being the definition of a
probable ore reserve of 70.8 million tonnes grading 1.1% copper, 0.61g/t gold and 121ppm
molybdenum. Importantly, the mining plan has restricted the overall average arsenic grade to
136ppm, with the highest grade in any single year restricted below 300ppm, to ensure that a
saleable concentrate is maintained throughout the project life. PNG represents approximately 8% (or
4.26 million ounces) of Harmonys proven and probable reserves. Harmony has indicated that it will
be looking at a partnership on the PNG assets, to assist in the development thereof.
Competitive Strengths
Leading market position in the attractive gold industry
|
|
|
We believe that our size and leading market position enables us to undertake exploration
and simultaneously develop multiple projects around the world, as well as secure capital on
competitive terms. |
|
|
|
|
The global gold industry offers a number of attractive industry fundamentals from which
we benefit. This includes the absence of available substitutes, relatively high barriers
to entry, and increasing gold producer concentration. |
|
|
|
|
We are developing new mines at a planned lower cost per ounce than our current
operations, which we believe will help make them robust enough to survive any margin
squeeze and to withstand any reversal in the gold price. We expect the gold price to
continue its upward trend in the medium term. |
Significant reserves with long mine lives
|
|
|
Harmonys ore reserves as of June 30, 2007 amounted to 53.67 million ounces of gold
spread across our assets in South Africa, Australia and PNG. This ore reserve base is
sufficient to support our existing operations in excess of 20 years at current production
levels. Year-on-year depletion accounted for 2.3 million ounces after disposals, shaft
closures and the loss of Western Area equity ounces of 5.4 million ounces. However, the
positive progress made with prefeasibility studies at the Evander South Project and at
Wafi/Golpu in PNG added 3.5 million ounces to reserves. |
|
|
|
|
Of the companys 53.67 million ounces of reserves, 41.5 million ounces are classified as
above infrastructure and 12.2 million ounces are classified below infrastructure (reserves
for which capital expenditure has still to be approved). |
Highly attractive project pipeline
|
|
|
We have a diverse portfolio of gold development projects spread across South Africa and
PNG. These projects include Elandsrand, Doornkop, Tshepong and Phakisa in South Africa,
and Hidden Valley in PNG, which, when developed, could deliver up to 1.4 million ounces of
additional production by 2011. |
22
|
|
|
We believe the relatively higher grade of these South African deposits and/or lower cost
base will result in these additional ounces being produced at highly competitive cash
costs. This in turn may result in a reduction in our overall cash cost position as these
new projects are commissioned. |
|
|
|
|
In addition to these projects, we have a number of additional development prospects that
are being considered and progressed, including the processing of sand dumps and tailings
dams in our Mega Dumps projects, the processing of rock dumps, and developing the
Wafi/Golpu copper/gold deposit in PNG, which, when all developed, could increase production
by a further 1.0 million ounces per annum. |
|
|
|
|
We have also expanded our exploration skill base, evidenced by our progress in PNG. |
|
|
|
|
We are also currently assessing potential options for our uranium deposits. |
Positive gold market outlook
|
|
|
The gold market continued its strong trend over the last year, with the fiscal 2007
average gold price of $694 per ounce. This increase in the gold price has been driven
predominantly by a combination of increased investment, consumer demand, flat mine
production and relatively weak US dollar. |
|
|
|
|
Increased investment demand has been one of the major catalysts behind a recent surge in
gold demand, with private investors now owning more gold than the governments of the world.
The reasons behind this increased demand are varied, and include: concerns over the future
of the U.S. economy and its currency; investors seeking portfolio diversification; the
launch of a number of gold exchange traded funds; and investors seeking a safe haven in
turbulent geopolitical tensions. |
|
|
|
|
We believe these fundamental drivers behind increased demand and decreased new supply of
gold will remain in the future, which will in turn support a higher gold price over this
period. As an unhedged gold producer, Harmony will benefit from a rising gold price
environment. |
|
|
|
|
In addition, the fundamental demand for gold appears to have continued with lower
official sales and an acceptance of a new floor price in the gold jewelry sector.
Producer de-hedging, combined with the continued decline in global gold output, underpins
the positive view. |
Increased focus on earnings margins and cost
|
|
|
Our aim to return to profitability is assisted by improved market conditions for South
African gold producers, but also importantly, through a restructuring of our portfolio to
increase productivity and optimize overall production levels, while closing or divesting
lower quality ounces. |
|
|
|
|
We are committed to lower our cost base and extensively benchmark our costing parameters
both internally between operations within Harmony, and externally against other gold
producers. |
|
|
|
|
We are confident that the benefits of our restructuring process and ongoing cost focus
will be sustained in the long term, and as a result, our ability to withstand any future
adverse market conditions has been significantly enhanced. |
Conservative balance sheet and low gearing
|
|
|
We maintain a conservative gearing policy and seek to fund ongoing capital expenditure
(excluding growth projects) through cash generated from existing operations. |
|
|
|
|
Our low level of gearing should provide us with the ability to utilize debt to fund
capital and development expenditure requirements for our new projects. |
23
Experienced management team with significant industry expertise
|
|
|
Our senior management team consists of experienced mining executives with extensive
industry backgrounds combined with geological and metallurgical expertise. |
|
|
|
|
Our senior management team has a proven track record in developing and managing the
operations under its control, and has demonstrated an ability to optimize underperforming
assets as well as developing new projects around the world. |
Leading Black Economic Empowerment strategy
|
|
|
Harmony is proud to be a South African company and fully embraces the countrys
transformation initiatives. We are 16% owned by African Rainbow Minerals (ARM Limited), a
black empowerment company in which our chairman, Patrice Motsepe, owns an interest. |
|
|
|
|
We believe that we have gone beyond the requirements of the Mining Charter by ensuring
that our historically disadvantaged South African (HDSA) partners are truly empowered,
that we are largely managed by a HDSA Board, and that we continue to engage with black
shareholders and/or partners to find more opportunities to invest in BEE transactions and
involve HDSA partners. |
|
|
|
|
We will continue to embrace empowerment as part of our growth strategy and we
acknowledge that empowerment forms a fundamental part of our business into the future. |
Strategy of organic growth
Harmonys organic growth strategy is focused on the extraction of high-quality ounces and
developing and operating our long-life mines. Through our back to basics approach of disciplined
mining, we aim to reduce costs and increase productivity. Our dedicated and participative
management team endeavours to meet production targets, reduce costs and optimize the orebodies
for the benefit of all our stakeholders.
Organic growth focused on high quality ounces
|
|
|
Harmonys extensive experience and ten-year track record of successfully identifying,
exploring and developing its own projects is a core component of our value creation
strategy. |
|
|
|
|
Our ongoing exploration programme is focused on both on-mine exploration, which
targets resources within the economic radius of existing mines, and new mine
exploration, which targets promising early to advanced stage projects around the world. |
|
|
|
|
Harmony is currently expanding its production base in South Africa and PNG, with a
focus on developing new mines at competitive cash costs and upgrading the overall
quality of our portfolio. |
|
|
|
|
We currently have a diverse project pipeline, comprising five projects that are well
advanced and, if all developed, could deliver up to an additional 1.4 million ounces of
low-cost production by 2011. These projects include Elandsrand New Mine, Doornkop South
Reef, Tshepong Sub 66 Decline and Phakisa in South Africa, and Hidden Valley in PNG,
which, if all developed, would contribute to a reduction in our overall cash costs per
ounce when they come on-stream. |
|
|
|
|
In addition to these projects, we have a number of additional development prospects
that are being progressed, including surface sand dumps, rock dumps and tailings dams,
reviewing the potential of our uranium deposits, and developing the Wafi/Golpu
copper/gold deposit in PNG, which, when an investment decision is taken by the board to
develop them once feasibility studies are complete, could increase production by up to a
further 1.0 million ounces. |
|
|
|
|
We have also expanded our exploration skill base, evidenced by our progress in PNG. |
24
Operational Strategy: Back to Basics:
Our operational strategy is underpinned by the back to basics strategy of disciplined mining,
cost control, ore reserve management and efficiency.
Empowered management teams
|
|
|
At each mining site, Harmony has established small, multi-disciplinary, focused
management teams responsible for planning and implementing the mining operations at the
site. Each of these teams is accountable for the results at its particular site and
reports directly to Harmonys Board. |
Active involvement and management
|
|
|
Annual operational goals and targets, including cost, volume and grade targets are
established in consultation with Harmonys executive committee for each mining site.
Each management team develops an operational plan to implement the goals and targets for
its mine site. Members of Harmonys executive committee review and measure the results
at each mining site on a regular basis throughout the year. |
Focus on increased productivity
|
|
|
Gold mining in South Africa is labor intensive, accounting for about 50% of Harmonys
South African operating costs. To control these costs, Harmony structures its
operations to achieve maximum productivity with the goal of having 60% of Harmonys
workforce directly engaged in stoping, or underground excavation, and development rock
breaking activities. |
Commitment to cost control
|
|
|
Harmony is committed to reducing its cost base and, to this end, Harmony benchmarks
its costing parameters both internally between operations within Harmony and externally
against other gold producers. |
Proactive maintenance practices
|
|
|
Harmony applies a principle of appropriate maintenance which allows it to spend
capital commensurate with the life of a specified operation. This principle ensures safe
operation and reduces capital that may be used ineffectively on mines that have a
limited life. |
Implementation of new systems
|
|
|
Harmony has implemented cost accounting systems and strict ore accounting and ore
reserve management systems to measure and track costs and ore reserve depletion
accurately, so as to enable it to be proactive in its decision making. |
Increasing consistency at our operations
|
|
|
We are committed to increasing the consistency of our operations, in terms of both
gold ore grades and production levels, in order to extract optimal value from our
orebodies. To achieve this, we have undertaken an intensive program over the last 18
months to significantly improve the mining flexibility of our operations by increasing
our development expenditure and focusing on comprehensive ore reserve management. We
have made significant progress on this objective, as evidenced by our substantially
improved development rates. |
|
|
|
|
We are currently reviewing potential opportunities in respect of certain deposits and
assets which we may develop independently of our core gold business, and in particular,
our uranium assets, of which the underground resources are not currently reflected on
our balance sheet or reserve statement. In respect of our Wafi/Golpu copper/gold
prospects, we may seek to develop those assets with partners. |
25
Selected acquisitions that diversify our operations and complement our competitive strengths
|
|
|
Harmony has a long track-record of acquisitions, having completed over 25
transactions over the last eleven years and successfully integrating each of these
operations into the Company. |
|
|
|
|
We possess broad and extensive gold mining experience gained through the development
and operation of both surface, opencast mines and mechanized, underground mines. This
breadth of expertise provides us with a competitive advantage when evaluation
acquisition opportunities. |
|
|
|
|
Our acquisition strategy is currently focused on establishing another major growth
area outside of South Africa by 2011. We believe that there is value in further
diversifying our production base outside of South Africa, as well as applying our broad
development and operational skills to new types of deposits. |
Targeted disposals that will upgrade our overall portfolio quality
|
|
|
Harmony has accumulated a diverse portfolio of assets, a number of which are nearing
the end of their productive lives for Harmony and are considered non-core to our
business. However, these assets may be of higher value to smaller producers who are less
concerned about short mine lives, and can still profitably operate these assets for a
number of years. |
|
|
|
|
As a result, we believe our disposal strategy will create value through the targeted
sale of these assets which for Harmony have relatively higher cost bases and/or shorter
mine lives. |
|
|
|
|
However, we will look to retain upside gold exposure from any disposal through gold
royalty arrangements. essentially a deferred purchase payment that is geared to
increased production and increased gold price. |
|
|
|
|
This disposal process is already well progressed, with an agreement entered into for
the sale of the Orkney operations in September 2007. This sale includes gold royalty
arrangements, and is due to be concluded by the first half of calendar 2008. |
|
|
|
|
We have also signed sale agreements or letters of intent for the disposal of our
Western Australian gold operations which includes South Kal and Mt Magnet. |
Initiatives that target specific opportunities
|
|
|
We acknowledge significant capital expenditure and a commitment to a long time
horizon are required to develop our projects into new mines. However, we firmly believe
that this is the foundation of Harmonys future, and to this end, have made substantial
investments in our major projects both in South Africa and PNG. |
Principal Investments
We have concluded several other strategic transactions within and outside South Africa in the
last three fiscal years, which are summarized below.
In March 2007, Harmony concluded negotiations with Rio Tinto plc (Rio Tinto) in which we
purchased Rio Tintos rights to the royalty agreement entered into prior to the acquisition by
Harmony of the Hidden Valley and Kerimenge deposits in PNG. The cost to Harmony of approximately
US$22.5 million (R158 million) will be met through the issue of shares and a cash payment of US$2.5
million (R18 million). The effect of the transaction will be to reduce the cost of gold produced at
Hidden Valley by US$13 per ounce, estimated at around US$35 million savings over the life of the
mine. The remaining condition precedent, which is to obtain approval of the relevant PNG minister
on the recommendation of the Mining Advisory Council that the royalty rights may be transferred to
Harmony, has not yet been satisfied. As a result the agreement was extended to the end of December
2007; however there can be no guarantee that the Mining Advisory Council will approve the transfer.
On June 21, 2006, Harmony announced that it had acquired 37.8% of the issued share capital of
Village Main Reef Gold Mining Company Limited (Village) for an amount of R458,775 (US$0.1
million). The equity stake was purchased from ARM Limited at a price of SA 20 cents per share. Due
to the fact that the acquisition surpasses the 35% mark, Harmony was obliged under the securities
Regulation Code on Takeovers and Mergers to extend an offer to the remaining shareholders of
Village to acquire all of their shares at
26
the same price at which it acquired the 37.8% stake. On August 14, 2006, Harmony announced
that minority shareholders holding 3,163 shares in Village (being 0.08% of the shares in respect of
which the offer was made) had accepted its offer. Harmony now holds 2,295,663 shares representing
37.83% of the issued share capital of Village. See Item 7. Related Party Transactions.
On March 9, 2006, Harmony announced that it had acquired a total of 44.9 million shares in
Western Areas Limited (Western Areas) for R2 billion (US$321 million), representing a 29.2% stake.
This was done by acquiring 37.37 million shares from Allan Gray and buying a total of 7.62 million
shares on the open market. To finance this acquisition, Harmony entered into a term loan facility
of R1.0 billion (US$280.8 million) with Rand Merchant Bank (RMB), for the purpose of partially
funding the acquisition of the 29.2% stake in Western Areas. Interest is compounded at a rate equal
to three-month JIBAR plus 1.5%. The loan amount is payable on March 13, 2007, and interest, which
is compounded monthly and payable quarterly from June 13, 2006. See Item 7. Related Party
Transactions. The loan was repaid during March and April 2007. See Item 5. Recently Retired
Credit Facilities and Other Borrowings.
On December 8, 2006 the Company disposed of its interest in Western Areas in exchange for Gold
Fields ordinary shares. This was in terms of an offer by Gold Fields whereby every 100 Western
Areas Shares were exchanged for 35 Gold Fields shares. The Company received 15.7 million Gold
Fields shares, issued at R135.02 (US$19.15) per share, for its 44.9 million Western Areas shares.
On October 18, 2004, Harmony announced the terms of a proposed merger between Harmony and Gold
Fields Limited offering 1.275 newly issued Harmony shares for each Gold Fields share. The proposed
merger was structured on the basis of an Initial Offer and a Subsequent Offer. As at December 1,
2004, Harmony had received valid acceptances of the Initial Offer in respect of a total of
57,993,991 shares representing approximately 11.5% of the entire issued share capital of Gold
Fields. Between November 30, 2004, and December 14, 2004, Harmony issued 72,173,265 offer shares as
consideration for the Initial Offer. On May 20, 2005, the Witwatersrand Local Division of the High
Court of South Africa ruled that Harmonys Subsequent Offer for Gold Fields had lapsed at midnight
on December 18, 2004. Accordingly, the Subsequent Offer was no longer in force and no Gold Fields
shares tendered into the Subsequent Offer were accepted. Harmony has since disposed of its Gold
Fields investment.
Disposals
See Item 8 Recent Developments for post-year end disposals.
The Company disposed of 1,150,000 Gold Fields shares for $19.7 million in a range of
transactions between January 26, 2007 and February 12, 2007. The total cost of these shares was
$21.4 million, resulting in a loss of $1.7 million. During May and June 2007, a further 1.5 million
shares with a cost of $28.3 million were disposed of for $25.1 million, resulting a a loss of $3.2
million.
In June 2007, Harmony announced that it has signed an agreement to divest of its nickel
tenements at its South Kalgoorlie Mines for A$20 million
(US$17 million) in cash, subject to certain conditions
precedent. The transaction is expected to conclude in the December 2007 quarter.
In April 2007, the surface assets and metallurgical plant at Deelkraal was sold to Ogoerion
Construction CC for R98 million ($13.7 million). It was agreed that the purchase price be paid in
installments over a 24-month period.
On October 19, 2006, Randfontein 4 shaft was sold to Simmer & Jack Limited for an amount of
R60 million ($8.5 million).
On March 31, 2006, the company disposed of the entire share capital of Buffalo Creek Mines
(Pty) Ltd for A$24 million (US$17.2 million). According to
the agreement the A$24 million (US$17.2 million) was to be
settled as follows: (i) A$4.3 million (US$3.1 million) to be paid in cash; (ii) 1,907,892 shares in GBS Gold
International, valued at A$5 million (US$3.6 million);
(iii) A$5 million (US$3.6 million) to be paid in cash in September 2006; (iv)
Shares in GBS Gold International, equal in value to
A$4.4 million (US$3.1 million), to be issued in September 2006;
and (v) A$5.4 million (US$3.8 million) to be paid in cash in September 2007. The net asset value of Buffalo Creek
Mines (Pty) Ltd was A$20.1 million (US$14.2 million), resulting in a profit of A$3.1 million (US$3 million). Final settlement was received as per contract in September
2007.
On
January 18, 2006, Harmony disposed of its investment in Atlas
Gold Limited for A$0.2 million (US$0.15 million). The
investment of 500,000 shares was carried at a total cost of
A$0.1 million (US$0.07 million),
resulting in a profit of A$0.1 million (US$0.07 million).
On December 29, 2005, Harmony disposed of its investment in San Gold Corporation for R19
million (US$3.1 million). The investment was carried at a total cost of R20 million (US$3.2
million), resulting in a loss of R1 million (US$0.1 million).
27
On November 16, 2005, the company disposed of the remaining portion of the Gold Fields
investment purchased in fiscal 2005 for R2.4 billion (US$361.8 million). The process was concluded
through market disposals which began on November 10, 2005 and an open market offering on November
15 and 16, 2005. The investment was acquired at a cost of R2.1 billion (US$316.4 million),
resulting in a profit of R307 million (US$45.4 million).
On June 3, 2005, the company disposed of 30 million shares in Gold Fields for R2 billion
(US$297.6 million). The investment was acquired at a cost of R2.4 billion (US$357.8 million),
resulting in a loss of R372 million (US$60.4 million).
On April 1, 2005 the Company disposed of its 12.7% holding in Bendigo Mining NL for $25.5
million, resulting in a realized profit of $4.9 million.
On February 3, 2005, Harmony undertook a secondary placing of 3,703,704 shares of its holding
in ARM Limited at a price of R27.00 (US$4.41) per share. On March 15, 2005, Harmony placed another 3,418,803
of its ARM Limited shares at a price of R29.25 (US$4.81) per share. On April 21, 2005, Harmony disposed of
its 14% investment in ARM Limited to the ARM Broad-Based Empowerment Trust (the ARM Empowerment
Trust) for a cash consideration of R829,827,460
(US$136,765,960) representing a price of R29.00 (US$4.78) per ARM Limited
share. The ARM Empowerment Trust has been established for the purpose of holding the ARM Limited
shares to further facilitate broad-based empowerment in ARM Limiteds shareholder base. ARM Limited
is Harmonys second largest shareholder and Broad-based Black Economic Empowerment (BEE) partner
holding 16% of Harmony. For U.S. GAAP purposes, Harmony did not recognize the disposal of its
investment in ARM Limited to the ARM Empowerment Trust as a sale. See Item 7. Major Shareholders
and Related Party Transactions and the consolidated financial statements included in this annual
report for a discussion on the treatment of this transaction.
Hedging Policy
Harmony has consistently maintained a policy of not entering into forward sales, derivatives
or hedging arrangements to establish a price in advance for the sale of our future gold production,
although we may do so in the future. As a result of this policy, Board approval is required when
hedging arrangements are to be entered into to secure loan facilities. Any change to this policy
requires ratification by the Board.
Where any such gold hedging position is acquired, Harmonys policy is to eliminate any such
positions existing within acquired companies as soon as this can be achieved through sound,
commercially advantageous transactions. There may, however, be instances where certain hedge
positions in acquired companies need to be kept in place for contractual or other reasons. In line
with this policy, Harmony has historically closed out hedging arrangements inherited through its
acquisitions. Harmonys revenues are sensitive to the Rand to U.S. dollar exchange rates as all
the revenues are generated by gold sales denominated in U.S. dollars. Harmony, does not enter into
forward sales, derivatives or other hedging arrangements to establish a Rand to U.S. dollar
exchange rate in advance for the sales of its future gold production.
In May 2007, Harmony closed out the remainder of its Australian hedge book, which it had
inherited with the acquisition of the Hill 50 mine. In total, some 220,000 ounces were closed out
at an average spot rate of A$809/ounce, for a total cost of A$72.8 million ($60.0 million). This
means that Harmony is now totally unhedged.
Description of Mining Business
Exploration
Exploration activities are focused on the extension of existing orebodies and identification
of new orebodies, both at existing sites and at undeveloped sites.
Our gold-focused exploration program has two components:
|
|
|
on-mine exploration, which looks for resources within the economic radius of existing
mines, and |
|
|
|
|
new mine exploration, which is the global search for early to advanced stage projects. |
28
Once a potential orebody has been discovered, exploration is extended and intensified in order
to enable clearer definition of the orebody and the potential portions to be mined. Geological
techniques are constantly refined to improve the economic viability of prospecting and mining
activities.
We conduct exploration activities on our own or with joint venture partners. As at June 30,
2007, our prospecting interest in South Africa measured 95,827 hectares (236,798 acres), 348,000
hectares (859,926 acres) in PNG and 325,088 hectares (803,310 acres) in Australia.
Harmony spent $26.9 million on exploration in fiscal 2007 and the bulk of exploration
expenditure was allocated to activities in Australia, PNG and South Africa with smaller
expenditures in other parts of Africa. In fiscal 2008, Harmony intends to carry out exploration in
PNG, Australia, South Africa and other parts of Africa.
Mining
The mining process can be divided into two main phases: (i) accessing the orebody and
(ii) mining the orebody. This basic process applies to both underground and surface operations.
|
|
|
Accessing the orebody. In Harmonys South African underground mines, access to the
orebody is by means of shafts sunk from the surface to the lowest economically and
practically mineable level. Horizontal development at various intervals of a shaft (known as
levels) extends access to the horizon of the reef to be mined. On-reef development then
provides specific mining access. In Harmonys Australian underground mines access to the
orebody is by means of declines. Horizontal development at various intervals of the decline
extends access to the horizon of the ore to be mined. The declines are advanced on a
continuous basis to keep ahead of the mining taking place on the levels above. In Harmonys
open pit mines, access to the orebody is provided by overburden stripping, which removes the
covering layers of topsoil or rock, through a combination of drilling, blasting, loading and
hauling, as required. |
|
|
|
|
Mining the orebody. The process of ore removal starts with drilling and blasting the
accessible ore. The blasted faces are then cleaned, and the ore is transferred to the
transport system. In open pit mines, gold-bearing material may require drilling and
blasting, and is usually collected by bulldozers or shovels to transfer it onto trucks,
which transport it to the mill. |
In Harmonys South African underground mines, once ore has been broken, train systems collect
ore from the faces and transfer it to a series of ore passes that gravity feed the ore to hoisting
levels at the bottom of the shaft. The ore is then hoisted to the surface in dedicated conveyances
and transported either by conveyor belts directly or via surface railway systems or roads to the
treatment plants. In addition to ore, waste rock broken to access reef horizons must similarly be
hoisted and then placed on waste rock dumps. In the Australian underground mines once ore has been
broken it is loaded into trucks, which transport it to the mill. In open pit mines, ore is
transported to treatment facilities in large-capacity vehicles. The Hidden Valley mine in PNG will
also be an open pit operation.
Processing
We currently have 9 operational metallurgical plants and 3 metallurgical plants on care and
maintenance in South Africa. We also have 2 operational metallurgical plants in Australia that
treat ore to extract the gold and intend to construct a metallurgical plant at the Hidden Valley
project in PNG. The principal gold extraction processes we use are carbon in leach, or CIL, and
carbon in pulp, or CIP.
The gold plant circuit consists of the following:
|
|
|
Comminution. Comminution is the process of breaking up the ore to expose and liberate
the gold and make it available for treatment. Conventionally, this process occurs in
multi-stage crushing and milling circuits, which include the use of jaw and gyratory
crushers and rod and tube and ball mills. Our more modern milling circuits include semi- or
fully-autogenous milling where the ore itself is used as the grinding medium. Typically, ore
must be ground to a minimum size before proceeding to the next stage of treatment. |
|
|
|
|
Treatment. In most of our metallurgical plants, gold is extracted into a leach solution
from the host ore by leaching in agitated tanks. Gold is then extracted onto activated
carbon from the solution using the CIL or CIP processes. |
Gold in solution, at one of our plants, is recovered using zinc precipitation. Recovery of
the gold from the loaded carbon takes place by elution and electro-winning. Cathode sludge or dore
bars produced from electro- winning is now currently sent directly to
29
Rand Refinery. Most of the South African plants no longer use smelting to produce rough gold
bars (dore). Harmonys Australian plants and its South African zinc precipitation plants continue
to smelt precipitate to produce rough gold bars. These bars are then transported to the Rand
Refinery or in the case of the Australian plants, to an independent refinery, which is responsible
for refining the bars to a minimum of good delivery status.
In fiscal 2006, we operated the only independent gold refinery and fabrication plant in South
Africa. In fiscal 2006, approximately 84% of Harmonys South African gold production was refined at
Harmonys refinery and the remainder was refined at the Rand Refinery, which is owned by a
consortium of the major gold producers in South Africa. The Australian gold production is refined
in Australia at an independent refiner, AGR Matthey. Since July 2006, all of our gold produced in
South Africa has been sent to the Rand Refinery, as a decision was made to close the Harmony
Refinery for economic reasons.
The South African government has emphasized that the production of value-added fabricated gold
products, such as jewelry, is an important means for creating employment opportunities in South
Africa and has made the promotion of these beneficiation activities a requirement of the Mining
Charter described in Item 4. Information on the Company Regulation Mineral Rights. Harmony
supports jewelry ventures in South Africa.
Harmonys Management Structure
We have a de-centralized management structure that is based on small, empowered management
teams led by General Managers at each of our operations. In South Africa, the General Managers
report to Alwyn Pretorius and Tom Smith, the Chief Operations Officers, and are responsible for
business optimization, ore reserve optimization, and for developing a business culture at the
operations. They also focus on long-term viability and growth of the operations. The General
Managers are supported by an Ore Reserve Manager, a Business Analyst and a Human Resources Leader
in ensuring the growth and long-term sustainability of the operations, and additional expertise and
skill is obtained from the Mining Managers, Engineers and Human Resource Managers who also report
to the respective General Managers.
Capital Expenditures
Capital expenditures for continuing operations, including the non-cash portion, incurred for
fiscal 2007 totalled $354.1 million, compared with $240.4 million for fiscal 2006 and $210.5
million for fiscal 2005. The focus of Harmonys capital expenditures in recent years has been
underground development and plant improvement and upgrades, and management currently expects the
focus to remain on its growth projects in fiscal 2008. These growth projects will require a great
deal of capital expenditure over the next two to three years and, given the current cash position
of the company, we are re-evaluating the planned capital expenditure, together with project
timelines. Additional funding options are being investigated, including debt raising and the
disposal of certain assets, such as the Cooke uranium dump. The increase in capital expenditure in
fiscal 2007 compared with fiscal 2006 resulted from the increased development in PNG, which
accounted for 45% of the capital expended in the year. Expenditure was also incurred at Doornkop
South Reef Project, Phakisa, Tshepong Sub 66 Decline and Elandsrand New Mine. The increase in
capital expenditures in fiscal 2006 compared with fiscal 2005 resulted from the commencement of
infrastructure establishment in PNG and further investment in the Doornkop South Reef Project,
Phakisa and Elandsrand mine. During 2006, the Company changed its accounting policy for the
capitalization of mine development costs. This change was made retrospectively, and comparative
numbers have been restated. See Item 5. Operating and Financial Review and Prospects Critical
Accounting Policies and Estimates for further information on the effects of this change on
Harmony. The focus of capital expenditures in fiscal 2005 resulted from the commencement of
infrastructure establishment in PNG and further investment in the Doornkop South Reef Project.
Capital expenditure for discontinued operations, including the non-cash portion, incurred for
fiscal 2007 totalled $26.9 million, compared with $24.9 million for fiscal 2006 and $25.8 million
for fiscal 2005.
Harmony has budgeted approximately $532.8 million for capital expenditures in fiscal 2008.
Details regarding the capital expenditures for each operation are found in the individual mine
sections under Business Harmonys Mining Operations. We currently expect that our planned
operating capital expenditures will be financed from operations and new borrowings as needed.
However, if we decide to expand major projects such as the Poplar Project and the Rolspruit Project
at Evander beyond our current plans, we may consider alternative financing sources described below.
See Item 4. Information on the Company Business Harmonys Mining Operations Evander
Operations.

Reserves
As at June 30, 2007, Harmony has declared proven and probable reserves of 53.67 million
ounces, broken down as follows: 48.95 million ounces in South Africa, 0.46 million ounces in
Australia, 4.26 million ounces in PNG (4.2 million ounces from Western Areas were exchanged for
shares in Gold Fields in December 2006 and are no longer included as part of Harmonys reserves).
Harmony uses the South African Code for the Reporting of Exploration Results, Mineral
Resources and Ore Reserves (the SAMREC Code), which sets out the internationally recognized
procedures and standards for reporting of mineral resources and ore reserves. Harmony uses the term
ore reserves herein, which has the same meaning as mineral reserves, as defined in the SAMREC
code. In reporting of reserves, we have complied with Industry Guide 7 of the United States
Securities and Exchange Commission.
For the reporting of Ore Reserves at our South African and Australian operations Harmony uses
a gold price of $520 per ounce. An exchange rate of R6.88 per U.S. dollar is used for South Africa
and for Australia an exchange rate of $0.73 per Australian dollar is used giving a gold price of
R115,000 per kilogram or AU$712 per ounce, respectively. These gold prices have also been used in
mine planning. At Papua New Guinea, the Hidden Valley feasibility study was completed using a base
case of US$520 per ounce (gold) and a silver price of US$8 per ounce and these prices have
therefore been used in the declaration of Ore Reserves.
In order to define that portion of a measured and indicated mineral resource that can be
converted to a proven and probable ore reserve, Harmony applies the concept of a cut-off grade.
This is done by defining the optimal cut-off as the lowest grade at which an orebody can be mined
such that the total profits, under a specified set of mining parameters, are maximized. The cut-off
grade is determined using Harmonys Optimiser computer program which requires the following as
input:
|
|
|
the database of measured and indicated resource blocks (per shaft section); |
|
|
|
|
an assumed gold price which, for this ore reserve statement, was taken as R115,000 per
kilogram; |
|
|
|
|
planned production rates; |
|
|
|
|
the mine recovery factor (MRF) which is equivalent to the mine call factor (MCF)
multiplied by the plant recovery factor; and |
|
|
|
|
planned cash costs (cost per tonne). |
Rand per tonne cash costs of the mines are historically based, but take into account distinct
changes in the cost environment, such as the future production profile, restructuring,
right-sizing, and other cost reduction initiatives which we expect in the aggregate to lead to
lower unit costs, and for below-infrastructure ounces, an estimate of capital expenditure.
The ore reserves represent that portion of the measured and indicated resources above cut-off
in the life-of-mine plan and have been estimated after consideration of the factors affecting
extraction, including mining, metallurgical, economic, marketing, legal, environmental, social, and
governmental factors. A range of disciplines which includes geology, survey, planning, mining
engineering, rock engineering, metallurgy, financial management, human resources management, and
environmental management have been involved at each mine in the life-of-mine planning process and
the conversion of resources into reserves. The ore flow-related modifying factors used to convert
the mineral resources to ore reserves through the life-of-mine planning process are stated for each
individual shaft. For these factors, 18-month historical information is used, except if there is a
valid reason to do otherwise. Because of depth and rock engineering requirements, some shafts
design stope support pillars into their mining layouts which accounts for approximately 7% to 10%
discounting. Further discounting relates to the life-of-mine extraction to provide for unpay and
geological losses.
Harmonys standard for narrow reef sampling with respect to both proven and probable reserve
calculations for underground mining operations at Elandskraal, Free State, Evander, Randfontein,
Freegold, Orkney and Target is applied on a 6 meter by 6 meter grid. Average sample spacing on
development ends is at 2 meter intervals in development areas. For the massive mining at the Target
operations, the Harmony standard for sampling with respect to both proven and probable reserves are
fan drilling with B sized diamond drill holes (43mm core) sited at 50 meter spaced sections along
twin access drives. Harmonys standard for sampling with respect to both proven and probable
reserves at its Australian underground operations includes sampling development drives and
crosscuts at intervals of up to 4 meters, drilling fans of diamond drill boreholes with a maximum
spacing of 20 meters in any
31
orientation within the orebodies, and assaying core at 1 meter intervals. The Kalgold open
cast operations are sampled on diamond drill and reverse circulation drill spacing of no more than
25 meters on average. Surface mining at South African operations other than Kalgold involves
recovering gold from areas previously involved in mining and processing, such as metallurgical
plants, waste rock dumps and tailings dams (slimes and sand) for which random sampling is used.
Australian surface operations are sampled on diamond drill and reverse circulation drill spacing of
no more than 20 meters on average.
Our mining operations reported total proven and probable reserves as of June 30, 2007 are set
out below:

Gold oz figures are fully inclusive of all mining dilutions and gold losses, and are reported
as mill-delivered tons and head grades. Metallurgical recovery factors have not been applied
to the reserve figures stated above. The approximate metallurgical recovery factors for the
table above are as follows: Elandskraal 97%; Free State 95%; Randfontein 96%; Evander 97%;
Kalgold 85%; Freegold 96%; Target 97%; Mt. Magnet 93%; South Kalgoorlie 92%; PNG 93%. In order
to derive the appropriate plant recovery factors for ore reserve estimates a process have been
followed where realistic assumptions based on historical performance have been applied. There
may be short term fluctuation either positive or negative which can lead to small
discrepancies between actual and planned recovery factors. |

Of Harmonys 53.67 million ounces of ore reserves, 41.5 million ounces are classified as above
infrastructure and 12.2 million ounces are classified as below infrastructure, those reserves for
which the capital expenditure has yet to be approved.
Of the decline in ore reserves, year-on-year depletion accounted for 2.3 million ounces after
disposals, shaft closures plus the loss of Western Area equity ounces amounts to another loss of
5.3 million ounces. This however was offset by ounces generated as a result of progress made with
pre-feasibility studies at the Evander South Project and at Wafi/Golpu in PNG which added 3.5
million ounces to reserves.
The amount of gold mineralization which Harmony can economically extract, and therefore can
classify as reserves, is sensitive to fluctuations in the price of gold. If gold prices differ from
the R115,000 per kilogram ($520 per ounce with an exchange rate of US$/R6.88 for South Africa and
A$/US$0.73 for Australia) that was used to estimate Harmonys attributable reserves of
53.67 million ounces of gold as of June 30, 2007 listed above, Harmonys operations would have had
different reserves. Based on the same methodology and assumptions as were used to estimate
Harmonys reserves as of June 30, 2007 listed above, but applying different Rand gold prices that
are 10% above or below the estimated Rand per kilogram gold price, the attributable gold reserves
for Harmonys operations would have been as follows:
|
|
|
|
|
R103,500 /kilogram (-10 percent) |
|
R115,000/kilogram |
|
R126,500 /kilogram (+10 percent) |
50.685 million ounces
|
|
53.67 million ounces
|
|
55.747 million ounces |
The London afternoon fixing price for gold on November 28, 2007 was $ 801.75 per ounce.
Harmonys methodology for determining its reserves is subject to change and is based upon
estimates and assumptions made by management regarding a number of factors as noted above under
Reserves. Accordingly, the sensitivity analysis of Harmonys reserves provided above should not be
relied upon as indicative of what the estimate of Harmonys reserves would actually be or have
34
been at the gold prices indicated, or at any other gold price, nor should it be relied upon as a basis
for estimating Harmonys ore reserves based on the current gold price or what Harmonys reserves
will be at any time in the future. See Risk Factors.

In line with the rest of the South African mining industry, and in an effort to reduce costs,
we have been rationalizing our mineral rights holdings in recent years. Accordingly, over the past
three years, we have disposed of our shares and participation rights in areas within and outside of
South Africa in which we have not actively pursued mining. However, in some cases we have retained
certain participation rights and option clauses in disposed of properties and mining rights. We may
continue to investigate further disposals.
Geology
The major portion of our South African gold production is derived from mines located in the
Witwatersrand Basin in South Africa. The Witwatersrand Basin is an elongated structure that extends
approximately 300 kilometers in a northeast-southwest direction and approximately 100 kilometers in
a northwest-southeast direction. It is an Archean sedimentary basin containing a six kilometer
thick stratigraphic sequence consisting mainly of quartzites and shales with minor volcanic units.
The majority of production is derived from auriferous placer reefs situated at different
stratigraphic positions and at varying depths below the surface in three of the seven defined
goldfields of the Witwatersrand Basin.
Harmonys production from the Australian operations and South African Kalgold operations are
sourced from Archaean greenstone gold deposits. These types of deposits are formed by the
interaction of gold-bearing hydrothermal fluids with chemically or rheologically suitable rock
types. The hydrothermal fluids are typically focused along conduits termed shear zones. The nature
of the shear zone and the host rock determines the style of the mineralization, which may be narrow
veins with high gold grades or wide disseminated mineralization with low-medium grades.
Harmonys Hidden Valley project comprises low sulphidation carbonate-base metal-gold
epithermal deposits within the Morobe Goldfield, in the Morobe Province of PNG. In the Hidden
Valley project area a batholith of Morobe Granodiorite (locally a coarse grained monzogranite) is
flanked by fine metasediments of the Owen Stanley Metamorphics. Both are cut by dykes of Pliocene
porphyry ranging from hornblende-biotite to feldspar-quartz porphyries. A number of commonly
argillic altered and gold anomalous breccias are known, including both hydrothermal and over
printing structural breccias. The Hidden Valley deposit area is dominated by a series of post
Miocene faults controlling the gold mineralization, including an early north trending set and the
main northwest faulting.
Harmonys Wafi project comprises the sedimentary/volcaniclastic rocks of the Owen Stanley
Formation that surround the Wafi Diatreme and host the gold mineralization. Gold mineralization
occurs as extensive high-sulphidation epithermal alteration overprinting porphyry mineralization
and epithermal style vein-hosted and replacement gold mineralization with associated wall-rock
alteration. The Golpu Copper-Gold project is located about one kilometer northeast of the Wafi gold
orebody. It is a porphyry (diorite) copper-gold deposit. The host lithology is a diorite that
exhibits a typical zoned porphyry copper alteration halo and the mineralized body can be described
as a porphyry copper-gold pipe.

Surface mining conducted at the South African operations other than Kalgold involves
recovering gold from areas previously involved in mining and processing, such as metallurgical
plants, waste rock dumps and tailings dams (slimes and sand).
In Australia, we presently conduct mining principally at two sites:
|
|
|
Mt. Magnet (we have signed a letter of intent for the sale of this operation See
Disposals above.) |
|
|
|
|
South Kalgoorlie (we have entered into an agreement for the sale of this operation
See Disposals above.) |
Underground and surface mining is conducted at each of these operations, with underground
access through two declines at Mt. Magnet and one decline at South Kalgoorlie and surface access
principally through open pits. Surface mining at South Kalgoorlie ceased in fiscal 2006 with
treatment consisting of Mt. Marion ore and low grade stockpiles. Open pit mining recommenced at
South Kalgoorlie mines during fiscal 2007. The Mt. Marion underground operation at South Kalgoorlie
Mines ceased in June 2007, with only open pit operations continuing on that site.

South African Mining Operations General
Introduction: On January 31, 2001, Harmony entered into an agreement to purchase the assets and
liabilities of the Elandskraal mines in the North West and Gauteng provinces of South Africa for
approximately R1 billion ($128.4 million). Harmony and AngloGold jointly managed the Elandskraal
mines between February 1, 2001 and April 9, 2001 and Harmony completed the purchase on April 9,
2001. The assets and liabilities of the Elandskraal mines include the mineral rights and mining
title (excluding a portion of the Carbon Leader Reef horizon, which AngloGold continues to mine),
mining equipment, metallurgical facilities, underground and surface infrastructure necessary for
the continuation of mining, ore treatment and gold extraction at Elandskraal as a going concern,
and contributions to a rehabilitation trust fund equivalent to the current rehabilitation liability
of this operation. The addition of Elandskraal to Harmonys operations increased Harmonys reserves
by approximately 9.9 million ounces at that time. In fiscal 2007, Harmonys Elandskraal operations
accounted for approximately 8% (7% in fiscal 2006 and fiscal 2005) of Harmonys total gold sales.
History: Gold mining began at Elandskraal in 1978 following approval of the project in 1974 by
Elandsrand Gold Mining Company for the Elandsrand operations and by Gold Fields of South Africa
Ltd. for the Deelkraal operations. Two surface shafts and two adjoining sub-vertical shafts were
sunk at Elandsrand and Deelkraal. The sub-vertical shafts at Elandsrand were completed in 1984,
which accessed a deeper reef in the lease area. The sub shaft deepening project, or SSDP, the
deepening of the sub-vertical shafts to approximately 3,600 meters below surface, has been
completed. Activities are currently focused on accessing and opening up areas of the new mine and
on the development and construction of support infrastructure. Harmony believes that the SSDP will
enable Elandskraal to produce approximately 364,954 ounces per year over the life of the mines.
39
Geology: Elandskraal contains three identified main reef groupings, the Ventersdorp Contact Reef,
or VCR, the Carbon Leader Reef, or CLR and the Mondeor Reef. Only the VCR is economic to mine and
has been mined at depths below surface between 1,600 and 2,800 meters with future production to
3,300 meters below surface at the Elandsrand operations and at depths below surface of 2,750 meters
at the Deelkraal operations. The VCR and CLR consist of narrow (20 centimeters to 2 meters) tabular
orebodies of quartz pebble conglomerates hosting gold, with extreme lateral continuity.
At the Elandsrand operations, the vertical separation between the VCR and CLR increases east to
west from 900 meters to 1,300 meters as a result of the relative angle of the VCR unconformity
surface to the regional stratigraphic strike and dip. The CLR strikes west-southwest and dips to
the south at 25 degrees. The VCR strikes east-northeast and has a regional dip of 21 degrees to the
south-southeast. Local variations in dip are largely due to the terrace-and-slope palaeotopography
surface developed during VCR deposition.
The dip of the VCR at the Deelkraal operations is relatively consistent at 24 degrees, although
there is some postulation of a slight flattening of dip at depth. The VCR has a limit of deposition
running roughly north-south through the center of the lease area. The VCR is not developed to the
west of this line. Some stoping has occurred to the west of this limit, but this was to exploit
reefs from the Mondeor Conglomerates, stratigraphically underlying the VCR.
Mining Operations: The Elandskraal operations are divided into the Elandsrand and the Deelkraal
mines. The Elandsrand mine engaged in both underground and waste rock mining. The Deelkraal mine
engaged in underground mining but as a result of the lower gold price in rand terms (taking into
account the stronger rand as against the U.S. dollar) the production was stopped in June 2004 and
remained closed during fiscal 2005, 2006 and 2007. The treatment of waste rock became uneconomical
and was discontinued during January 2004. These operations are subject to all of the underground
and waste rock mining risks detailed in the Risk Factors section.
Following our acquisition of Elandskraal, we implemented the Harmony Way at Elandskraal in an
effort to cut costs and increase productivity, which resulted in the retrenchment of approximately
1,450 employees. This has improved the overall cost structure, which has enabled us to pursue
capital development.
The Elandsrand mine, a mature mine with a declining production profile, has the challenge of a
new mine being developed underneath the old mine. Due to the operating depths of the Elandskraal
underground operations, seismicity and pressure related problems are a risk. Harmony regularly
revisits its mining strategy and management procedures at all of its deeper mining operations in
connection with its efforts to mitigate this risk. The primary challenges facing the Elandskraal
operations are the lowering of working costs, increasing mining flexibility, controlling capital
expenditure and the timely completion of the SSDP by fiscal 2010.
During August and September 2004, a major restructuring plan was implemented at Elandsrand. Along
with the implementation of Continuous Operations or CONOPS between August 2004 and February 2005,
production improved. Even so, it is still hampered by the lack of flexibility, an issue that will
be addressed by the commissioning of the new mine. Capital development on three levels has been
completed. Cash operating cost development is taking place in both easterly and westerly directions
on these levels. Access development delays on two other levels resulted from slow progress of the
access haulages through the Cobra Dyke. All the levels up to 113 Level are now through and
developments rates have picked up substantially. Development and construction of support
infrastructure has been completed. Work on the chambers for the refrigeration plants on 100 Level
and the pump chamber on 115 Level is proceeding. The project is expected to be completed by fiscal
2010 and is expected to have a life of mine of 20 years. From the inception of the project through
the end of fiscal 2007, R684 million (US$95.0 million calculated at the closing rate at balance
sheet date) has been expended. A further R305 million (US$42.3 million calculated at the closing
rate at balance sheet date) has been budgeted to complete the project. Good progress has been made
with the Elandsrand New Mine Project.
In October 2007, an incident occurred at the Elandsrand operation involving a compressed pipe
column which broke off below the shaft surface bank and fell to the bottom of the men and -
material shaft, causing extensive damage to the shaft steel work and electrical cables. The
incident resulted in 3,000 workers being stranded underground for more than 30 hours. Mining
operations were temporarily suspended for 44 days to allow for repairs to be conducted in the
shaft. On November 16, 2007 the Company announced
that a tripartite team, consisting of management, unions and the Department of Minerals and Energy
had found the shaft to be in good working condition. Elandsrand mine was brought back into
operation o November 19, 2007 after it followed precautionary safety procedures during the start up
of underground workings. Management presented its the findings of the investigation to the DME
relating to the pipe failure, emergency power, water and evacuation services and procedures, as
well as the impact of CONOPS on maintenance. While the emergency services were found to be
acceptable, Harmony has revised its emergency procedures and is in the process of completing a new
Code of Practice relating to emergency preparedness. The DME is also expected to begin its own
inquiry into the incident at the end of November 2007. Conditions in the working places, following
a 44 day period during which no production took place, were found to be better than expected.
Production at Elandsrand has resumed, and it is anticipated that the
40
shaft will be back on full
production in December 2007. The losses due to the suspended production will be finalized and
released at the end of the December 2007 quarter.
An agreement for the implementation of CONOPS at Deelkraal was reached with the respective unions
on December 19, 2003. Due to delays, it was only fully operational by April 2004. Despite this,
production at the Deelkraal mine was stopped in June 2004 as a result of the reduction in the
Rand-denominated price of gold at that time which made mining at the shaft uneconomical. During
fiscal 2005 and 2006 the Deelkraal mine was only operating as a service shaft.
Safety: During fiscal 2007, the safety record at the Elandskraal mine in terms of lost time
frequency rate 18.49 per million hours worked compared unfavorably with the group average of 15.27.
Significant work was done to address the seismic risk described above and the fatality frequency
rate (0.08) returned to a more consistent ratio with the group average of 0.22 for underground
operations. Safety standards from other Harmony operations are being applied at Elandskraal and
receive constant and high-level attention.
Plants: Commissioned in 1978, the Elandsrand Plant has milling in closed circuit with primary and
secondary hydrocyclones, secondary ball milling in closed circuit with hydrocyclones, thickening
and cyanide leaching in a CIP pump cell carousel circuit. The CIP was commissioned after an upgrade
of the facility in 1999. Following post-acquisition capital improvements, loaded carbon milled at
the Elandsrand Plant is transported by road to the Central Plant at Virginia for elution,
electro-winning and smelting to produce gold. Residues from the CIP are pumped either to a backfill
plant or directly to the tailings facility. Ore from Elandsrand underground operations are
delivered to the plant for treatment. Due to a high percentage of freegold a gravity separator is
used to extract this gold. The sludge from this concentrator is then transported by air to the
Target Plant for extraction and smelting.
The following table sets forth processing capacity and average tons milled during fiscal 2007 for
the plant:

Randfontein Operations
Introduction: The Randfontein gold mine is located in the Gauteng Province of South Africa,
approximately thirty kilometers west of Johannesburg. The Randfontein mine currently operates under
a mining authorization with a total area of 17,753 hectares. The Randfontein mine has both
underground and surface mining operations, and has two metallurgical plants. Underground mining is
conducted at Randfontein at depths ranging from 500 meters. In fiscal 2007, the Randfontein
Operation owns the Cooke, Doornkop and Lindum shafts. Harmonys Randfontein operations accounted
for approximately 13% (13% in fiscal 2006 and 11% in fiscal 2005) of Harmonys total gold sales.
History: Gold mining began at the Randfontein mine in 1889. Harmony obtained management control of
Randfontein in January, 2000 and by June 30, 2000 had acquired 100% of Randfonteins outstanding
ordinary share capital and 96.5% of the warrants to purchase ordinary shares of Randfontein. Since
acquiring Randfontein, we have implemented the Harmony Way at Randfontein. We have reduced the
number of senior managers, sold off non-core assets and implemented management teams.
Geology: The Randfontein mine is situated in the West Rand Goldfield of the Witwatersrand Basin,
the structure of which is dominated by the Witpoortjie and Panvlakte Horst blocks, which are
superimposed over broad folding associated with the southeast plunging West 50 Rand Syncline. The
structural geology in the north section of the Randfontein mine is dominated by a series of
northeast trending dextral wrench faults.
42
The Randfontein mine contains six identified main reef groupings: the Black Reef; the Ventersdorp
Contact Reef; the Elsburg Formations; the Kimberleys; the Livingstone Reefs; and the South Reef.
Within these, several economic reef horizons have been mined at depths below surface between 600
and 1,260 meters.
The reefs comprise fine to coarse grained pyritic mineralization within well developed thick quartz
pebble conglomerates or narrow single pebble lags, which in certain instances are replaced by
narrow carbon seams.
Mining Operations: The Randfontein operations are engaged in both underground and waste rock
tunneling also takes place underground. These operations are subject to all of the underground and
waste rock mining risks detailed in the Risk Factors section, and have historically also been
subject to the open pit mining risks. Due to the shallow to moderate depths of the operations,
seismicity and pressure related problems are infrequent. There is a risk of subterranean water
and/or gas intersections in some areas of the mine. However, this risk is mitigated by active and
continuous management and monitoring, which includes the drilling of boreholes in advance of faces.
Where water and/or gas are indicated in the drilling, appropriate preventative action is taken.
The Doornkop South Reef Project was announced on January 22, 2003. The project involves the
deepening of the Doornkop main shaft to 1,973 meters to the South Reef, which lies between 1,650
and 2,000 meters below surface, and includes development towards these mining areas. The estimated
final capital cost is R1.284 million (US$178.3 million), with R610 million (US$84.72 million) spent
as of June 30, 2007. After some initial suspensions, mining commenced at the South Reef at
Doornkop in January 2004.
Currently, the Kimberley Reef is mined on the upper levels of the Doornkop Shaft between 900 and
1,100 meters below surface. Most of this mining is taking place on channel edges, which results in
sporadic high, but mostly low recovered grades. Mining from this reef is planned to cease during
fiscal 2008 with all focus being directed at the South Reef.
The South Reef on the lower levels is the target of the proposed shaft-deepening project. The most
significant achievement for the past year was the completion of the shaft sinking programme. The
shaft was sunk from two positions simultaneously, a world first as far as we know. The programme
culminated with the removal of the plug between 192 and 197 levels, where a deflector was installed
on 197 level allowing for loading of the rock from 197 level and for other operations to continue
below in the shaft on 212 level. Although a very high risk exercise on paper, the programme was
engineered and executed on time with few significant problems.
The upper portion of shaft (from 132 level to 192 level) has been equipped on the dual purpose
compartment allowing for materials to be transported to the levels as they are equipped. 192 level
is currently equipped to provide all the stoping materials required for the mining programme that
will commence in July 2007. Sustaining the development programme via the sub shaft infrastructure
has been a challenge, as has the development of our people to take on the operation of a new mine.
Key milestones that are expected to be achieved during fiscal 2008 include the Rock Winder
commissioning by December 2007 and the main shaft that will be partially equipped by the end of
December 2007. The main shaft will be commissioned for 90,000 t/month to be hoisted by end March
2008. The Rock Winder is expected to be hoisting by June 2008.
First gold was produced from the project in July 2007. Full production (135,000 tons) is expected
to be reached by March 2010.
Safety: The safety record at the Randfontein operations during fiscal 2007 in terms of lost time
frequency rate of 10.04 per million hours worked compared favorably with the group average of
15.27. The fatality frequency rate (0.46) compared unfavorably with the group average of 0.22 for
underground operations.
Safety at the operations receives constant and high-level attention and where problems are
identified steps are taken to address the situation. The Chief Operating Officer is responsible for
leading initiatives to improve workplace health and safety at Harmonys South African operations.
Plants: The processing facilities at the Randfontein mine presently comprise two operating plants:
the Cooke metallurgical plant and the Doornkop metallurgical plant, both of which are serviced by a
surface rail network. The Cooke metallurgical plant, commissioned in 1977, is a hybrid CIP/CIL
plant, which processes the ore from the dumps from the Randfontein operations. The Doornkop
metallurgical plant, commissioned in 1985, is a conventional CIP plant, which is used to treat
waste rock and other surface accumulations. It is now treating all ore from underground from the
Randfontein operations.

In fiscal 2007, the Cooke plant recovery has been approximately 81%, while Doornkop plant recovered
approximately 95% of the gold contained in the ore delivered for processing. During fiscal 2006,
the Doornkop plant was upgraded and all underground tons were moved from Cooke plant to Doornkop
plant, Cooke plant was mothballed in January 2006 but was recommissioned during fiscal 2007 to
treat surface sources.
Introduction: Harmonys Free State operations are comprised of the original Harmony mines, the
Unisel mine, Saaiplaas shaft 3, the Masimong shaft complex (comprised of Masimong shafts 4 and 5),
Brand shafts 2, 3 and 5, and the Vermeulenskraal North mineral rights area. Mining is conducted at
Harmonys Free State operations at depths ranging from 620 meters to 3129 meters. In fiscal 2007
Harmonys Free State operations accounted for approximately 19% (18% in fiscal 2006 and 15% in
fiscal 2005) of Harmonys total gold sales.
History: Harmonys Free State operations began with the Harmony mine, which is an amalgamation of
the Harmony, Virginia and Merriespruit mines. Beginning in 1996, Harmony began purchasing
neighboring mine shafts. The Unisel mine was purchased in September 1996, the Saaiplaas mine shafts
2 and 3 were purchased in April 1997, the Brand mine shafts 2, 3 and 5 were purchased in May 1998
and the Masimong complex (formerly known as Saaiplaas shafts 4 and 5) was purchased in September
1998.
44
Geology: Harmonys Free State operations are located in the Free State goldfield on the
south-western edge of the Witwatersrand Basin. Within this area, the operations are located on the
south-western and south-eastern limb of a synclinal closure, with the Brand, Saaiplaas and Masimong
shafts occupying northerly extensions of the same structure. The reefs dip inwardly from their
sub-outcrop positions in the east and south of the mine to a position close to the western boundary
of the original Harmony mine, where the reefs abut against the De Bron fault. To the west of the De
Bron faulted zone, faulting is generally more intense, resulting in structurally more complex
mining conditions.
Mining Operations: The Free State operations are engaged in both underground and waste rock mining.
These operations are subject to all of the underground and waste rock mining risks detailed in the
Risk Factors section. Due to the shallow to moderate depths of the underground operations,
seismicity and pressure related problems are relatively infrequent with the exception of the Brand
shafts where these problems receive constant attention. Harmony regularly revisits its mining
strategy and management procedures in connection with its efforts to mitigate risks of these
problems. There is a risk of subterranean water and/or gas intersections in some areas of the mine.
However, this risk is mitigated by active and continuous management and monitoring, which includes
the drilling of boreholes in advance of faces. Where water and/or gas is indicated in the drilling,
appropriate preventative action is taken. The principal challenges at the Free State operations of
achieving optimal volumes and grades of ore production are addressed by stringent ore reserve
management.
In fiscal 2002, Harmony began implementing the Masimong Expansion Project, which includes
developing the Basal and B Reef orebodies in the Masimong shaft area and equipping the shaft. The
envisaged growth from the project was not realized in 2005 and 2006, and as a result the project
was halted in June 2006.
During fiscal 2005, Masimong was affected by three underground fires (one of which stopped
production for seven days in the last quarter), machinery break-downs, a go-slow strike in January
2005 and a regional strike in March 2005. CONOPS was implemented in the third quarter of fiscal
2006.
During fiscal 2005, Masimong 4 was placed on care and maintenance.
The Brand 2 and the Brand 5 shafts are currently on care and maintenance. Care and maintenance will
remain in place until market conditions are more favorable or more economical parts of the orebody
are discovered. All labour has been transferred to other Harmony operations, where they have
augmented natural attrition positions or displaced contractor labour.
Safety: The safety record at the Free State operations during fiscal 2007 in terms of lost time
frequency rate of 17.82 per million hours worked was higher than the group average of 15.27. The
fatality frequency rate (0.22) is equal with the group average for underground operations lost.
Plants: There are two metallurgical plants at the Free State operations, namely Central and
Saaiplaas plants. A third plant, Virginia plant, was closed in fiscal 2005 and clean up operations
implemented. The Central plant was commissioned in 1986 and employs CIP/CIL hybrid technology. It
is currently dedicated to the treatment of underground ore. The Saaiplaas plant, commissioned in
the late 1950s, has been converted from the zinc precipitation filter process to the CIL. It
currently processes surface sources and reclaimed slime.

Introduction: Harmonys Evander operations are located in the province of Mpumalanga in South
Africa and are comprised of an amalgamation of the former Kinross, Bracken, Leslie and Winkelhaak
mines and 36,898 hectares of mineral rights adjacent to these mines. Mining at Harmonys Evander
operations is conducted at depths ranging from 300 meters to 2,100 meters. In fiscal 2007,
Harmonys Evander operations accounted for approximately 10% (12% in fiscal 2006 and 13% in fiscal
2005) of Harmonys total gold sales.
History: Gold mining in the Evander Basin began in 1955. Eventually, four mining operations were
established at Evander. In 1996, as a result of depletion of ore reserves, all four mining areas
were merged to form Evander. In August 1998, Harmony acquired Evander as a wholly-owned subsidiary.
Since then, we have implemented the Harmony Way management process at Evander.
Geology: The area covered by Evanders mining authorization and mineral rights is situated within
the Evander basin, a geologically discrete easterly extension of the main Witwatersrand Basin. Only
one economic placer unit, the Kimberley Reef, is mined at Evander. In addition to the faulting of
the reef horizon, there are numerous dykes and sills that complicate the mining layouts, the most
significant of which is an extensively developed dolerite footwall sill that occasionally
intersects the Kimberley Reef, causing displacements within it.
Mining Operations: The Evander operations are primarily engaged in underground mining. The Evander
operations also process a limited amount of waste rock as and when necessary to allow the plants to
operate efficiently. These operations are subject to all of the underground mining risks detailed
in the Risk Factors section. Due to the shallow to moderate depths of the Evander underground
operations, seismicity and pressure related problems are relatively infrequent. There is a risk of
subterranean water and/or gas intersections in some areas of the mine. However, this risk is
mitigated by active and continuous management and monitoring, which includes the drilling of
boreholes in advance of faces. Where water and/or gas is indicated in the drilling, appropriate
preventative action is taken. In fiscal 2004, an agreement was reached with the unions for the
implementation of CONOPS at Evander. It has been fully implemented at all shafts at Evander. The
implementation resulted in an increase in tons milled and consequently a rise in gold production.
During fiscal 2005, the Evander 2 and 5 shafts were combined and downscaled, while the Evander 9
shaft was closed successfully and placed on care and maintenance. The Evander 9 shaft employees
were transferred to other Evander operations. The Evander 7 shaft (Decline No. 3, phase 3) project
is currently under review due to geological complexities.
46
Safety: The safety record at the Evander operations in terms of lost time frequency rate of 18.56
per million hours worked during fiscal 2007 is higher than the group average of 15.27. The fatality
frequency rate (0.32) during fiscal 2007 is also higher than the group average of 0.22 for
underground operations.
Plants: Evander has one active processing plant, the Kinross-Winkelhaak plant, which is operated
as two geographically distinct sections. The bulk of the mines ore production is treated at the
Kinross plant, which is a CIP/CIL hybrid plant. The Winkelhaak plant mills all of the ore from
shafts 2 and 5, and pumps the slurry to the Kinross plant for further processing. .

Introduction: Harmony conducts a surface mining operation at the Kalgold gold mine near Mafikeng
in the North West Province of South Africa. Through Kalgold, we also control extensive mineral
rights on the Kraaipan Greenstone Belt in the North West Province of South Africa. We purchased
Kalgold on July 1, 1999. In fiscal 2007, the Kalgold operations accounted for approximately 2% (3%
in fiscal 2006 and 4% in fiscal 2005) of Harmonys total gold sales.
History: Harmony acquired Kalgold on July 1, 1999 and fully incorporated Kalgold into its
operations in October 1999. Prior to our acquisition, the Kalgold mine had operated for more than
three years.
Geology: The Kalgold operations are situated on the Kraaipan granite-greenstone belt, which is a
typical gold-bearing greenstone formation. It has undergone intense structural deformation that has
led to its dislocation into separate units.
Within the mining lease area, six steeply dipping zones of mineralization have been identified.
Several additional zones of mineralization have been located within this area and are being
evaluated. The first zone to be exploited by open cast mining has been
47
an area known as the D-Zone. The D-Zone orebody has a strike length of 1,400 meters, varying in width between 40 meters in the
south and 15 meters in the north.
Gold mineralization is associated with pyrite and pyrrhotite, which was developed as a replacement
mineral within a banded ironstone formation and also within extensional, cross-cutting quartz veins
within the ironstone.
Mining Operations: The Kalgold operations are engaged in open pit mining. This operation is
subject to all of the open cast mining risks detailed in the Risk Factors section. Small
subterranean water intersections in the pit are common and are actively managed and appropriate
action is taken when necessary. The primary mining challenges at the Kalgold operations of
achieving optimal volumes and grades of ore production are addressed by stringent ore reserve
management.
Safety: The Kalgold operations had a lost time injury frequency rate of 6.08 per million hours
worked in fiscal 2007, and recorded no fatal accidents in fiscal 2007. There is no reliable
industry benchmark for safety at South African surface mining operations.
Plants: Ore is trucked from the pit and is directly tipped into the feed bin to the pre-primary
crusher or stockpiled. The ore then undergoes a four phase crushing process before it reaches the
Dome stockpile. Three ball mills are used to grind the ore down to between 70-80% less than 75
micron for the leaching process.
The replacement of a pre-aeration tank is in progress and is due for completion in December 2007.
The estimated capital cost at completion amounts to
R 2.5 million (US$0.35 million).

Introduction: On April 23, 2002, Harmony and ARMgold acquired the Freegold operations from
AngloGold through a joint venture with ARMgold in which Harmony and ARMgold each had a 50% interest
for $206.8 million. Since Harmony acquired ARMgold in September 2003, the Freegold operations have
been accounted for as a wholly owned subsidiary. For the year ended June 30, 2007, the Freegold
operations accounted for 27% (26% in fiscal 2006 and 27% in fiscal 2005) of Harmonys total gold
sales.
Freegold assets consist of the Joel, Tshepong, Matjhabeng, Bambanani and St. Helena mines,
associated infrastructure and other mineral rights in the Free State Province of South Africa.
Production from the underground mines and adjacent surface sources is processed through three
processing facilities (the Free State 1, or FS1, Plant, Joel Plant and the St. Helena Plant).
History: Exploration, development and production history in the area of the Freegold assets dates
from the early 1900s, leading to commercial production by 1932. Subsequent consolidation and
restructuring led to the formation of Free State Consolidated Gold Mine (Operations) Limited, which
became a wholly-owned subsidiary of AngloGold in June 1998. AngloGold also owned the Joel mine,
which, although it was not a part of this AngloGold subsidiary, is now included within the Freegold
assets owned by Freegold. Freegold also acquired the St. Helena gold mine in October 2002. St.
Helena was the first gold mine to be established in the Free State.
Geology: Freegolds mines are located in the Free State goldfield, which is on the southwestern
edge of the Witwatersrand basin. The Bambanani, Tshepong, Matjhabeng and St. Helena mines are
located in and around Welkom, while the Joel mine is approximately 30 kilometers south of Welkom.
Mining at Bambanani, Tshepong and Matjhabeng is primarily conducted in the Basal reef, with limited
exploitation of secondary reefs. Mining at Joel is primarily conducted in the Beatrix-VS5 Composite
Reef. The reefs generally dip
49
towards the east or northeast while most of the major faults strike
north-south, with the most intense faulting in evidence at Matjhabeng.
Mining Operations: Freegold is engaged in both underground and waste rock mining. These operations
are subject to all of the underground and waste rock mining risks detailed in the Risk Factors
section. Freegold regularly revisits its mining strategy and management procedures at the Freegold
operations in connection with its effort to minimize risks. Mining depths range from
shallow-intermediate at the Joel mine to deep at the Bambanani mine. The primary mining challenges
at the Freegold operations are seismic risks, ventilation and fire avoidance. Both the Bambanani
mine and the Matjhabeng mine (consisting of Kudu/ Sable, Eland and Nyala shafts) are classified as
seismically active operations with seismic monitoring systems installed to do active seismic risk
evaluation, generally located in the vicinity of remnant operations and/or geological structures.
Seismic systems are managed by external specialists. Current ventilation and refrigeration systems
were evaluated and improved at take-over which Harmony believes will improve productivity and
safety. Plans to this effect are being implemented by Freegold. Refrigeration plants are installed
at the Bambanani and Tshepong Mines. Following underground fires during the second half of 1999 at
the Bambanani mine, mine management reviewed and modified working practices and the efficiency of
the overall fire management system.
Mining is conducted at depths ranging from 1,200 and 3,000 meters at Bambanani, at an average depth
of approximately 1,925 meters at Tshepong, at an average depth of approximately 1,700 meters at
Matjhabeng, at an average depth of approximately 1,000 meters at Joel and at an average depth of
1,489 meters at St. Helena. Production at Matjhabeng, which is a mature mine nearing closure, is
currently focused on the extraction of remnant pillars and shaft pillars, specifically at the Eland
shaft. Due to the increased operating costs in dollar terms, in fiscal 2005 the loss making shafts
Nyala and Eland were placed on care and maintenance, while production at St. Helena was scaled down
and Kudu/Sable was closed down.
Freegold is conducting a development program at the Bambanani shaft, which is nearing completion.
Harmony expects this program to allow access to additional mining areas, which would reduce overall
grade but increase overall production and life of mine.
CONOPS was introduced at the shafts during the quarter ended December 31, 2003. During a
significant period of fiscal 2005, CONOPS was stopped due to a dispute between management and the
unions.
The Tshepong Decline project, which started in April 2003, has accessed an additional two levels
(69 and 71) of the Tshepong North Shaft. At fiscal 2007 year end, R254.7 million (US$ 35.4 million
calculated at the closing rate at balance sheet date) has been spent. A further R25.6 million (US$
3.6 million calculated at the closing rate at balance sheet date) has been budgeted to complete the
project. Except for two rock passes, the development portion of the project work has been
completed. Freegold estimates that the project work will be completed by June 2008 and is expected
to make available an additional 43,481 kilos Au (1.4 million ounces)
The Phakisa Shaft Project is also proceeding on schedule. Phakisa shaft, a surface shaft, sunk to
75 level elevations and a planned decline shaft to 85 levels will access the ore reserves to a
depth of 2,662 meters below surface. It is estimated that the area will yield 22.0 million tons,
recovering 185.2 tons of gold over a project life of 22 years. Project completion requires sinking
of a decline shaft, equipping and commissioning of the shaft with access development and stoping to
maximum production build-up at a capital cost of R934 million (US$130 million calculated at the
closing rate at balance sheet date). To date, R614 million (US$85 million calculated at the closing
rate at balance sheet date) has already been spent. The project is expected to be in full
production in 2010. The average production rate over the peak period of life of mine is 281,693
ounces per annum.
Shaft 2 at St.Helena mine was closed during the quarter ended December 31, 2003. CONOPS was
introduced on November 2003. During a significant period of fiscal 2005, CONOPS was stopped due to
a dispute between management and the unions.
Nyala shaft was placed on care and maintenance during March 2005. During June 2005, the decision
was made to place the remaining shafts at Matjhabeng, being Kudu/Sable and Eland, on care and
maintenance.
Safety: During fiscal 2007, the lost time frequency rate at the Freegold operations of 18.08 per
million hours worked compared unfavorably with the group average of 15.27 while the fatality
frequency rate of 0.23 nearly equalled the group average of 0.22.
Safety standards receive constant and high-level attention at Freegold.
Plants: Freegold operates one plant: the Free State One (FS1) Plant. This plant, which processes
underground ore, waste rock and various surface accumulations, was commissioned in 1986 and is a
conventional CIP plant processing ore that has been milled by semi-autogenous grinding. Gold is
recovered from the eluate solution using zinc precipitation and a precoat vacuum filter. The
precipitate recovered from the filter is calcined and smelted to bullion. The FS2 Plant was largely
dedicated to the treatment of surface
50
sources but due to the past low gold price in rand terms the
plant became uneconomical and since the Free State plants have extra capacity, it was decided to
stop treatment at the plant and to start a total clean up operation in fiscal 2005. It was
commissioned in the early 1950s and employs conventional crushing and filtration technology. The
Joel plant is a hybrid CIP/CIL plant and was commissioned in 1987. During fiscal 2005, it was
decided to close the Joel Plant and implement clean up operations. St. Helena operates a
conventional zinc precipitation filter plant supported by two mills. Treatment at St. Helena plant
was stopped in the latter part of the year and the plant was placed on care and maintenance.

In fiscal 2007, Harmonys plants at its Free State One Plant recovered approximately 96% of the
gold contained in the ore delivered for processing.
Introduction: On September 22, 2003, Harmony and ARMgold completed a merger via a share exchange
which resulted in ARMgold becoming a wholly owned subsidiary of Harmony. For accounting purposes,
the merger was accounted for as a purchase by Harmony of ARMgold for a purchase consideration of
$697 million. For fiscal 2005, 2006 and fiscal 2007, the ARMgold operations accounted for
approximately 5% of Harmonys total gold sales. In September 2007, Harmony announced it had
entered into formal agreements with Pamodzi Gold for the sale of the Orkney Shafts. See Item 8. -
Recent Developments below.
51
History: The ARMgold operations consist of the Welkom shafts in the Free State Province and the
Orkney shafts in the North West Province. Due to the distance, they are operated as separate
business units. Exploration, development and production in the Welkom area dates back to the 1940s
leading to production by 1947. Exploration and development at Orkney started from 1886 and
following dormant periods, large-scale production commenced during the 1940s with the formation of
Vaal Reefs Gold Mining and Exploration Company Limited in 1944.
Geology: The Welkom operations are centrally located within the Free State goldfield, which lies
some 270 kilometers southwest of Johannesburg on the southwest rim of the Witwatersrand Basin, in
an area containing several other mature operations. The Basal Reef is the main reef exploited here.
It strikes north to north-northwest and generally dips to the east between 20 degrees and 40
degrees. Other reefs that are exploited are the Leader Reef, the Saaiplaas Reef and the Middle
Reef. There are a number of faults in this area, including Rheedersdam and De Bron.
At the Orkney operations, the Vaal Reef is the most significant reef mined. The reef strikes
northeast, dipping southeast and is heavily faulted to form a series of graben structures. The dip
is generally less than 30 degrees but can vary locally in direction and magnitude to exceed 45
degrees. The VCR is also exploited, as well as the Elsburg Reef. There are several major faults in
the lease area, being Nooitgedacht, Buffelsdoorn, Witkop, WK2, No 3 BU, No 5 BU and No 2 BU Fault.
These faults typically have throws of tens of meters and further divide the reef into blocks of up
to 100 meters in width.
Mining operations: ARMgold is engaged in underground mining at all of its operations. These
operations are subject to all of the underground mining risks detailed in the Risk Factors section.
ARMgold regularly revisits its mining strategy and management procedures at both its operations in
connection with its effort to minimize risks. Mining depths range from 1,000 meters to 1,200 meters
below the surface at the Welkom operations and from 1,600 meters to 2,000 meters below the surface
at the Orkney operations.
Cost control was one of the major challenges faced at the ARMgold operations. Since the merger,
management has implemented the Harmony Way in an effort to cut costs and increase productivity.
During fiscal 2005, Welkom 1 and Orkney 6 were placed on care and maintenance. Harmony approved the
re-opening of the Orkney 7 shaft during fiscal 2006 and production commenced during the first
quarter of fiscal 2007.
Safety: During fiscal 2007, the safety record at ARMgold mines in terms of lost time frequency rate
of 22.54 million hours worked compared unfavorably with the group average of 15.27. The fatality
frequency rate of 0.26 compared less than favorable with the group average of 0.22 . Significant
work is being done to address this.
Plants: ARMgold does not own any plants. Ore from the Orkney operations is treated at Vaal River
Operations (VRO) No. 1 Gold Plant (of Anglo Gold Ashanti). Various agreements between Harmony
and VRO govern the supply and quality of the ore and gold apportionment.

Introduction: Avgolds operations consist of the Target mine, Target North and Extensions and Oribi
Exploration Property situated near the town of Allanridge in the Free State Province, some 270
kilometers southwest of Johannesburg. Located at approximately latitude 28 (LOGO) 00S and
longitude 26 (LOGO) 30E on the northern limit of the Welkom Goldfields, the site is accessed via
the R30 motorway situated between the towns of Bothaville and Welkom.
On July 15, 2003, Harmony acquired 11.5% in Avgold from Anglo South Africa Capital (Pty) Ltd and
later that year acquired ARM Limiteds 42% share in Avgold. Through a scheme of arrangement,
Harmony acquired the minority shareholding and Avgold became a wholly owned subsidiary. In fiscal
2006 and 2007 Avgolds operations accounted for 6% of Harmonys total gold sales (7% in fiscal
2005).
History: The Target Operations area was initially explored through surface drilling in the late
1980s with further exploration being undertaken from a 5.6 kilometers long decline, commenced in
1995, driven from 203L at Lorraine No. 1 shaft. A positive feasibility study into the development
of a 105 ktpm operation was produced in May 1998 resulting in the decision to develop the Target
mine. A detailed mine design was produced in 2000 and the mine officially opened in May 2002. Upon
closure of the Lorraine mine in August 1998, the Lorraine No. 1 and No. 2 shafts were transferred
to the Target mine, becoming Target No. 1 and No. 2 shafts, respectively.
Geology: The gold mineralization currently exploited by Target mine is contained within a
succession of Elsburg and Dreyerskuil quartz pebble conglomerate reefs hosted by the Van Heeverrust
and Dreyerskuil Members of the Eldorado Formation, respectively. Additional mineral resources have
been delineated in the Big Pebble Reefs of the Kimberley Formation but these are not planned to be
exploited in the current life of mine plan.
53
The majority of the mineral reserves at Target mine are contained within the Eldorado fan, a
structure with dimensions of some 135 meters vertically, 450 meters down-dip and 500 meters along
strike. The Eldorado fan is connected to the subsidiary Zuurbron fan, located between the Target
mine and Lorraine, by a thinner and lower grade sequence of Elsburg reefs termed the Interfan area.
To the north of the Eldorado fan, a number of fans have been intersected by surface drilling of
which the Siberia and Mariasdal fans are the most significant. These fans are subject to ongoing
technical studies and do not form part of the current Target mine life of mine mineral reserve.
A number of faults that displace the reefs of the Target mine have been identified of which the
most prominent are the north-south trending Eldorado fault and the east-west trending Dam and Blast
faults. The Eldorado uplifts the more distal portions of the Elsburg and Dreyerskuil Reefs while
the Blast fault forms the northern border of the Target mine.
Target North is sub-divided into the Paradise, Siberia and Mariasdal areas by the east-west
trending Siberia and Mariasdal faults. To the north of the Siberia fault, the Eldorado fault
continues trending more to the northwest and an additional north-south trending fault, the Twin
fault has uplifted the distal portions of the reefs. North of the Maraisdal fault, the reef
horizons are at a depth greater than 2,500 meters below surface. Resources have been delineated on
strike up to 15 kilometers north of the Target mine
Approximately 40 kilometers north of Target mine, surface boreholes have intersected gold bearing
reefs in the Oribi area close to the town of Bothaville. Resources have been delineated at Oribi on
the VCR and Elsburg at depths of approximately 2,750 meters below surface.
Mining operations: The Avgold operations are engaged in underground and surface mining. Mining
operations comprise one primary underground mine commissioned in May 2002, making use of
information systems and mechanization, combined with process-driven organizational design that
relies on a multi-skilled workforce. The majority of the production is derived from mechanized
mining; however, conventional stoping is still employed primarily to de-stress areas ahead of the
mechanized mining. The Avgold operations have been managed by Harmony since May 2004. The Harmony
Way has been successfully implemented resulting in a decrease of cash costs.
During fiscal 2005, Target struggled with flexibility problems and a lack of access points to the
orebody, despite a good start to the year. There were also several operational disruptions,
including low availability of the mechanized fleet and consequently, low development rates.
Critical machines have been replaced with new and refurbished equipment in an attempt to improve
the availability of the fleet. CONOPS was also implemented in the conventional mining section which
allowed the mine to step up the rate of over-stoping the massives.
Safety: The safety record at the Avgold operations during fiscal 2007 in terms of lost time
frequency rate of 9.81 per million hours worked compared favorably with the group average of 15.27
while the fatality frequency rate of 0.0 compared favorably with the group average of 0.22 for
underground operations.
Safety at the operations receives constant and high-level attention and where problems are
identified steps are taken to address the situation. The Chief Operating Officer is responsible for
leading initiatives to improve workplace health and safety at Harmonys South African operations
Plants: Target Plant was commissioned towards the end of 2001 and currently treats only underground
ore. The process route comprise primary crushing, open circuit primary SAG milling, secondary ball
milling closed with hydrocyclones, thickening, cyanide leaching, CIP adsorption, elution,
electrowinning, smelting and tailings disposal. The milling circuit incorporates gravity
concentration, the concentrates from which are processed via intensive cyanidation and
electrowinning. Gold bullion is dispatched to the Rand refinery.
The installation of a ROM mill to enable the mill to run autogenously is progressing well. The
objective is to save R 1.2 million on grinding media monthly. To date, a total of R14.8 million
($2.0 million) has been spent. Capital cost still to be incurred is expected to be R7. 0 million
($0.9 million).

South African Operations Production Analysis
We manage our operations on a shaft-by-shaft basis. Since fiscal 2006, we categorized the South
African operations as follows: Quality assets, Leveraged assets and Growth assets. Surface
operations are managed separately.
Quality assets are typically those shafts with a larger reserve base and longer life, which form
the core of our production. The Quality assets are Target, Tshepong, Masimong complex, and Evander
2, which was downscaled and combined with Evander 5 during fiscal 2005, Evander 7, Evander 8 and
Cooke 1, 2 and 3 shafts.
Leveraged assets are those shafts that supplement production and provide the upside in the event of
an increase in the rand gold price. The leveraged operations consist of shafts that are either in
the process of being restructured, downscaled in line with available ore reserves or mothballed.
These include the currently operating Bambanani, Joel, West Shaft, Harmony 2, Merriespruit 1 and 3,
Unisel, Brand 3 and Orkney 2, 4 and 7 shafts, as well as St. Helena which was scaled down
significantly and Brand 5, Welkom 1, Kudu/Sable, Nyala and Eland that were placed on care and
maintenance or closed down during fiscal 2005. West shaft was placed on care and maintenance in
March 2007. The following shafts that were closed during fiscal 2004 were also Leveraged assets:
Evander 9, Deelkraal, Saaiplaas 3, Welkom 1, 4, 6 and 7, as was Harmony 4 and Virginia, which was
closed during fiscal 2003. In September 2007, Harmony announced the sale of the Orkney shafts to
Pamodzi Gold, this transaction is expected to be concluded by the first half of 2008.
Growth assets comprise the expansion projects established through existing infrastructure, as well
as the three new mines being built in South Africa. These operations include the Elandsrand and
Doornkop mines and the Phakisa project. The Growth assets represent the future of our South African
operations and, once completed, will result in a substantial improvement in the quality of our
production profile.
In addition, surface operations comprise the Kalgold opencast mine, all previously mined rock,
introducing waste or reef and any clean-up operations at plants and other infrastructure.
Therefore, the surface operations at Freegold, the Free State and Randfontein and, for the first
time in fiscal 2005, Targets surface operations are also included under surface operations as well
as the surface operations from Elandsrand and Evander, which were discontinued in fiscal 2004.
Quality assets
The charts set out on the pages that follow detail the operating and production results from
underground operations for all identified Quality assets for fiscal 2007, 2006, and 2005:

Tons milled from Quality Assets decreased to 6,814,000 in fiscal 2006, compared with 7,464,000
in fiscal 2005. Volumes were negatively affected, mainly as a result of days lost to the industry
through the wage strike in the first quarter and the Cosatu strike in the fourth quarter (See
Board of Directors, Senior Management and Employees Unionized Labor), the influence of the
CONOPS agreement that were only concluded in October 2005 in the Freegold operations and lower
underground volumes. Recovered grade decreased from 0.185 in fiscal 2005 to 0.167 in fiscal 2006.
The decrease in ounces sold from 1,378,165 in fiscal 2005 to 1,141,166 is attributable primarily to
the decrease in the tons produced and the recovered grade.

Tons milled from Quality assets increased to 6,901,000 in fiscal 2007, compared with 6,814,000 in
fiscal 2006. Recovered grade decreased from 0.167 in fiscal 2006 to 0.155 in fiscal 2007. The
decrease in ounces sold from 1,141,166 in fiscal 2006 to 1,068,902 is attributable primarily to a
decrease in the recovered grade.
Gold sales increased to $682.0 million in fiscal 2007, compared with $606.4 million in fiscal 2006
and $588.4 million in fiscal 2005. Cash costs for the Quality assets were $442 per ounce of gold in
fiscal 2007, compared with $383 per ounce of gold in fiscal 2006. This increase was mainly as a
result of the lower grade and higher cash costs.

Tons milled from the Target shaft decreased to 813,000 in fiscal 2006, compared with 1,178,000
in fiscal 2005. The decrease in tons milled was primarily due to flexibility issues and machine
availability (and hence low development rates). We also took a strategic decision during the year
to undertake vehicle maintenance in-house, replacing our external contractor agreement in December
2005 with our own labor. This changeover period had a major impact on the production levels. Ounces
sold were 150,196 in fiscal 2006, compared with 209,847 in fiscal 2005. The decrease in ounces sold
was negatively influenced by the lack of volumes. The recovery grade increased from 0.178 in fiscal
2005 to 0.185 in fiscal 2006.
Cash costs for Target were $51.9 million in fiscal 2006, compared with $54.3 million in fiscal
2005. This decrease was primarily attributed to lower production levels, a reduction in plant
treatment costs and the termination of the external contractor vehicle maintenance contract. Cash
costs per ounce were $346 in fiscal 2006, compared with $259 in fiscal 2005. This increase was
attributable primarily to the lower production volumes. In addition there was a 7.5% depreciation
of the Rand against the U.S. dollar during the year. See Operating and Financial Review and
Prospects Exchange Rates. If expressed in Rand terms, costs per ounce would have increased in
fiscal 2006, due primarily to lower production volumes, increases in costs of labor and supplies
and the effect of inflation on supply contracts.
Tons milled from the Target shaft increased to 904,000 in fiscal 2007, compared with 813,000 in
fiscal 2006. The age of the current fleet (vehicles) is of a big concern. There is a replacement
strategy in place and delivery is awaited. Action plans are in place to improve the skills levels
and the maintenance systems.
Ounces sold were 142,433 in fiscal 2007, compared with 150,196 in fiscal 2006. The decrease in
ounces sold, was negatively influenced by the lower grade. The recovery grade decreased from 0.185
in fiscal 2006 to 0.158 in fiscal 2007.
Cash costs for Target were $52.7 million in fiscal 2007, compared with $51.9 million in fiscal
2006. This increase was primarily attributed to higher production levels, and an increase in labor
cost. Cash costs per ounce were $370 in fiscal 2007, compared with $346 in fiscal 2006. This
increase was attributable primarily to a lower recovery grade as well as an increase in cash costs.
The Target shafts hoisting capacity is 110,000 tons per month. The average tons milled in fiscal
2007 was 68,675 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 22.0 million tons (4.3
million ounces) will be sufficient for the Target shaft to maintain
56
production until approximately
2026. However, any future changes to the assumptions upon which the reserves are based, as well as
any unforeseen events affecting production levels, could have a material effect on the expected
period of the future operations.
Capital expenditure: Harmony incurred approximately R120.5 million ($16.7 million) in capital
expenditure at the Target shaft in fiscal 2007, principally for underground development and the
replacement of the underground fleet. Harmony has budgeted R 285.5 million ($39.7 million at the
closing rate at balance sheet date) for capital expenditure at Target in fiscal 2008, primarily for
underground development, as well as the replacement of the underground vehicles.

Tons milled from the Tshepong shaft increased to 1,786,000 in fiscal 2006, compared with
1,700,000 in fiscal 2005. This increase was attributable primarily due to the re-implementation of
CONOPS with effect from mid-November 2005. Ounces sold were 335,289 in fiscal 2006, compared with
380,695 in fiscal 2005. This decrease was attributable to the decrease in recovery grade to 0.188
in fiscal 2006, compared with 0.224 in fiscal 2005. The decrease in recovery grade was primarily
due to decreases in the shaft and plant call factors.
Cash costs for the Tshepong shaft were $111.5 million in fiscal 2006, compared with
$101.1 million in fiscal 2005. This increase was primarily attributed to the re-implementation of
CONOPS during the year. The effect of CONOPS increases costs in the short term as additional people
are utilized without being fully operational, but to increase profitability in the longer term as
higher volumes have a positive impact on the bottom line. Cash costs per ounce were $332 in fiscal
2006, compared with $266 in fiscal 2005. This increase was attributable primarily due to decrease
in the number of ounces of gold produced. In addition, there was a 7.5% depreciation of the Rand
against the U.S. dollar during the year. See Operating and Financial Review and Prospects
Exchange
Rates. If expressed in Rand terms, costs per ounce have increased by 28% in fiscal 2006,
primarily due to increases in the costs of labor and supplies and the effect of inflation on supply
contracts.
Tons milled from the Tshepong shaft increased to 1,824,000 in fiscal 2007, compared with 1,786,000
in fiscal 2006. Ounces sold were 318,887 in fiscal 2007, compared with 335 289 in fiscal 2006. This
decrease was attributable to the decrease in recovery grade to 0.175 in fiscal 2007, compared with
0.188 in fiscal 2006. The decrease in recovery grade was primarily due to decreases in the shaft
call factor, plant call factor and the average mining grade which was 1365 cmg/t in fiscal 2007,
compared to 1440 cmg/t in fiscal 2006, in line with the Life of Mine (LOM) profile. Industry
standard practice in South Africa is to report drill results and cut-off grades for resource
estimates in gold as thickness-grade values (cmg/t).
Cash costs for the Tshepong shaft were $112.0 million in fiscal 2007, compared with $111.5 million
in fiscal 2006. In a CONOPS environment, the profitability in the longer term will be realized by
higher volumes which have a positive impact on the bottom line. Cash costs per ounce were $351 in
fiscal 2007, compared with $332 in fiscal 2006. This increase in unit cost was attributable
primarily due to decrease in the number of ounces of gold produced. Cash costs have increased by
5.2% in fiscal 2007, primarily due to increases in the costs of labor and supplies and the effect
of inflation on supply contracts.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 24.7 million tons (5.1
million ounces) will be sufficient for Tshepong to maintain underground production until
approximately 2020. Any future changes to the assumptions upon which the ore reserves are based, as
well as any unforeseen events affecting production levels, could have a material effect on the
expected period of future operations.
Capital Expenditure: Harmony incurred approximately R187.7 million ($26.1 million) in capital
expenditures at the Tshepong shaft in the fiscal year ended June 30, 2007, primarily for the
decline project and ongoing development. Harmony has budgeted R204.3
57
million ($28.4 million at the
closing rate at balance sheet date) for capital expenditures in fiscal 2008. This capital include
the completion of the current Sub 66 Decline of R25.6 million (US$3.6 million), the new Sub 71
decline (additional two levels 73 and 75) R39.1 million (US$5.4 million), B Reef exploration
project R4.9 million (US$0.7 million), Rail Bound Equipment conversion R0.8 million (US$0.1
million) and ongoing development of R110.3 million (US$15.3 million)

Tons milled from the Masimong shaft complex were 1,020,000 in fiscal 2006, compared with
1,046,000 in fiscal 2005, and ounces sold were 136,153 in fiscal 2006, compared with 159,981 in
fiscal 2005. Year-on-year production was slightly lower, with the decrease in ounces primarily due
to the decrease in the recovered grade, and the days lost to the industry (through, the wage strike
in the first quarter and the Cosatu strike in the fourth quarter). Production was stopped at
Masimong 4 shaft in April 2005. The resultant decrease in production from this shaft was offset by
an increase in production at the Masimong 5 shaft. Development was started in May 2006 at the
Masimong 4 shaft to utilize this shaft for ventilation purposes. CONOPS were implemented towards
the end of the fiscal 2006. Recovered grade was 0.133 in fiscal 2006, compared with 0.153 in fiscal
2005, mainly as a result of a lower shaft call factor from poor fragmentation and excessive water
usage underground. Initiatives have been put in place to remedy these problems, and we expect to
see improvement from July 2006.
Cash costs were $66.6 million in fiscal 2006 compared, with $65.4 million in fiscal 2005 with
cash costs per ounce at $489 in fiscal 2006, compared with $409 in fiscal 2005. This increase in
cash costs per ounce was attributable primarily to the decrease in the recovered grade and higher
labor costs as we employed approximately 600 people for the implementation of CONOPS. The effect of
CONOPS increases costs in the short term as additional people are utilized without being fully
operational, but to increase profitability
in the longer term as higher volumes have a positive impact on the bottom line. In addition,
there was a 7.5% depreciation of the Rand against the U.S. dollar during the year. See Operating
and Financial Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce
have increased by 23% in fiscal 2006, due primarily to lower production volumes, increases in the
costs of labor and supplies and the effect of inflation on supply contracts.
Tons milled from the Masimong shaft complex were 1,074,000 in fiscal 2007, compared with 1,020,000
in fiscal 2006, and ounces sold were 147,958 in fiscal 2007, compared with 136,153 in fiscal 2006.
Year on year production was slightly higher with a slightly higher recovery grade.
Cash costs were $82.8 million in fiscal 2007 compared with $66.6 million in fiscal 2006 with cash
costs per ounce at $560 in fiscal 2007 compared with $489 in fiscal 2006. This increase in cash
costs are mainly attributable to increase in labor costs as a result of the annual wage increases
as well as a 21% increase in number of employees. This increase in people was to fully staff the
operation for Continious Operations. This was the first year that Masimong was fully onto
Continious Operations cycle. The effect of CONOPS increases costs in the short term as additional
people are utilized without being fully operational, but to increase profitability in the longer
term as higher volumes have a positive impact on the bottom line.
The total shaft hoisting capacity is 134,000 tons per month. The average tons milled in fiscal 2007
were 81,000 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 10.0 million tons (1.7
million ounces) will be sufficient for the Masimong shaft complex to maintain underground
production until approximately fiscal 2016. Any future changes to the assumptions upon which the
reserves are based, as well as any unforeseen events affecting production levels, could have a
material effect on the expected period of future operations.

Capital Expenditure: Harmony incurred approximately R109.0 million ($15.1 million) in capital
expenditures at Masimong in fiscal 2007,.. Harmony has budgeted R119.0 million ($16.6 million at
the closing rate on balance sheet date) for capital expenditures at Masimong in fiscal 2007,
primarily for growth development of the Masimong shaft complex.

No tons were produced from the Evander 2 in fiscal 2007 or in fiscal 2006, compared with
357,000 tons in fiscal 2005. This decrease in ore milled was due to the decision to downscale the
operations and combine it with the Evander 5 shaft during fiscal 2005.
The total shaft hoisting capacity for the Evander 2 is 51,000 tons per month. In fiscal 2006
the hoisting capacity of this shaft has been combined with that of Evander 5.
Due to the economic climate, mining operations at Evander 2 and 5 were combined and downscaled
during fiscal 2005. Harmony currently expects that production at Evander 2 and 5 will end between
2009 and 2010. Any future changes to the assumptions upon which the reserves are based, as well as
any unforeseen events affecting production levels, could have a material effect on the expected
period of future operations. See Risk Factors Risks Relating to Our Business and Our Industry
Harmonys gold reserve figures are estimated based on a number of assumptions, including
assumptions as to mining and recovery factors, future cash costs of production and the price of
gold and may yield less gold under actual production conditions than currently estimated.
Capital Expenditure. Harmony incurred no capital expenditures at Evander 2 in fiscal 2007 or
2006. No provision was made for capital expenditures at Evander 2 in fiscal 2008.
Due to the recent economic climate, mining operations at Evander 2 shaft were combined with those
at Evander 5 shaft and downscaled during fiscal 2005.

Tons milled from the Evander 5 were 450,000 in fiscal 2006, compared with 245,000 in fiscal
2005, and ounces sold were 62,388 in fiscal 2006, compared with 47,093 in fiscal 2005. The increase
in tons milled was due to the successful combination and restructuring of the Evander 2 and 5. The
increase in ounces was due to the significantly higher production. Recovered grade was 0.139 in
fiscal 2006, compared with 0.192 in fiscal 2005. The lower recovered grade was primarily due to the
expected depletion of the high grade No. 5 Shaft pillar during the year.
59
The increase in cash costs per ounce from $338 in fiscal 2005 to $530 in fiscal 2006 was
attributable primarily to the additional labor incurred by Evander 5 due to the downscaling and
restructuring of the No. 2 shaft operation. In addition, there was a 7.5% depreciation of the Rand
against the U.S. dollar during the year. See Operating and Financial Review and Prospects
Exchange Rates. If expressed in Rand terms, costs per ounce have increased by 61% in fiscal
2006, due primarily to increases in the costs of labor and supplies and the effect of inflation on
supply contracts.
Tons milled at Evander 5 were 377,000 in fiscal 2007, compared with 450,000 in fiscal 2006, and
ounces sold were 55,643 in fiscal 2007, compared with 62,388 in fiscal 2006. The decrease in tons
milled was due to the depletion of the open raise lines on 24 level and 80% of mining happens in
pillars now. The decrease in ounces was due to the significantly lower production in reef tons.
Recovered grade was 0.148 in fiscal 2007, compared with 0.139 in fiscal 2006. The higher recovered
grade was primarily due to an improvement of the MCF from 62% in 2006 to 70.5% in 2007.
The decrease in cash costs from $530 per ounce in fiscal 2006 to $520 per ounce in fiscal 2007 was
attributable primarily to the lower cash cost resulting from the restructuring of the no.2 and no.5
operations, which decreases labor , equipment and material costs. Production took place in higher
grade areas in 2007 therefore reducing cash cost per ounce.
The total shaft hoisting capacity at Evander 5 is 40,000 tons per month. The average tons milled in
fiscal 2007 was 27,000 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 2.4 million tons (0.4
million ounces) will be sufficient for Evander 5 to maintain production until approximately fiscal
2010. Mining operations at the No. 2 and 5 shafts were combined due to the fact that there are
synergies between these shafts and the pillars being mined now are smaller than in previous years
(Lenses being mined). Harmony currently expects that production at shafts 2 and 5 will end between
2009 and 2010. In addition, any future changes to the assumptions upon which the reserves are
based, as well as any unforeseen events affecting production levels, could have a material effect
on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R39.2 million ($5.4 million) in capital
expenditures at Evander 5 in fiscal 2007. Harmony has budgeted R42.9 million ($6,0 million at the
closing rate at the balance sheet date) for capital expenditures at the Winkelhaak operations in
fiscal 2008, primarily for ongoing development and the upgrading of major equipment.

Tons milled from the Evander 7 were 435,000 in fiscal 2006, compared with 541,000 in fiscal
2005, and ounces sold were 83,202 in fiscal 2006, compared with 130,009 in fiscal 2005. The
decrease in tons milled was primarily due to significantly lower production in the No. 3 decline
due to a major sill intrusion in December 2005 that eliminated two entire raise lines. The
decrease in ounces sold is attributable primarily to lower production levels and the decrease in
recovery grade, which decreased to 0.191 in fiscal 2006, compared with 0.240 in fiscal 2005. The
grade decrease was primarily attributable to the depletion of a very high grade payshoot area
during the year.
The increase in cash costs per ounce from $252 in fiscal 2005 to $392 in fiscal 2006 was
attributable primarily to the decrease in the recovered grade, and hence fewer ounces produced.
Cash cost remained fairly constant at $32.6 million in fiscal 2006 versus $32.8 million in fiscal
2005. See Operating and Financial Review and Prospects Exchange Rates. If expressed in Rand
terms,
60
costs per ounce have increased by 60% in fiscal 2006, due primarily to lower production
volumes, increases in the costs of labor and supplies and the effect of inflation on supply
contracts.
Tons milled from the Evander 7 shaft were 447,000 in fiscal 2007, compared with 435,000 in fiscal
2006, and ounces sold were 61,044 in fiscal 2007, compared with 83,202 in fiscal 2006. The increase
in tons milled was due to increase in mining of pillar areas. The decrease in ounces sold is
attributable primarily to the decrease in recovery grade, which decreased to 0.137 in fiscal 2007,
compared with 0.191 in fiscal 2006. The grade decrease was primarily attributable to the depletion
of a very high grade pay shoot in the No 3 decline areas and the increase in mining in the uppers
area of the shaft (pillar area) that is of lower grade. The shaft also started to hoist waste with
reef in October 2006 due to infrastructure constraints.
The increase in cash costs from $392 per ounce in fiscal 2006 to $633 per ounce in fiscal 2007 was
attributable primarily to the decrease in the recovered grade, and hence fewer ounces produced.
Cash cost increased to $38.6 million in fiscal 2007 from $32.6 million in fiscal 2006.
The total shaft hoisting capacity for the Evander 7 shaft is 53,000 tons per month. The average
monthly tons milled in fiscal 2007 were 32,135.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 4.9 million tons (0.9
million ounces) will be sufficient for Evander 7 shaft to maintain production until approximately
fiscal 2008. We expect production to end in 2008 because by then all the production will take place
in the pillar areas at much lower grade and therefore higher cash cost per ounce which will render
the shaft unprofitable. Restructuring of the shaft will start during 2008. The shaft will continue
with geological drilling in the sill breakthrough area. Labor will be re-deployed to Evander 8 and
other shafts in the group where production build up is taking place. Any future changes to the
assumptions upon which the reserves are based, as well as any unforeseen events affecting
production levels, could have a material effect on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R85.7 million ($11.9 million) in capital
expenditures at Evander 7 in fiscal 2007, principally for underground declines at shaft 7. Harmony
has budgeted Rand 42.4 million ($5.9 million at the closing rate at the balance sheet date) for
capital expenditures at Evander 7 in fiscal 2008, primarily for ongoing development and opening up.

Tons milled from the Evander 8 shaft were 815,000 in fiscal 2006, compared with 734,000 in
fiscal 2005, and ounces sold were 128,849 in fiscal 2006, compared with 151,936 in fiscal 2005.
This increase in tons milled was due to an improved mining flexibility and improvement in face
advance as a result of the successful implementation of CONOPS during fiscal 2005 continuing in
fiscal 2006. The decrease in ounces was due to the significantly lower recovered grade. Recovered
grade was 0.158 in fiscal 2006, compared with 0.207 in fiscal 2005, which is the result of payshoot
variability that impacts on grade as a result of sequential mining.
The increase in cash costs per ounce from $273 in fiscal 2005 to $348 in fiscal 2006 was
attributable primarily due to the significant decrease in the recovery grade. In addition, there
was a 7.5% depreciation of the Rand against the U.S. dollar during the year. See Operating and
Financial Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have
increased in fiscal 2006 by 31%, due primarily to lower production volumes, increases in the costs
of labor and supplies and the effect of inflation on supply contracts.

Tons milled from the Evander 8 shaft were 842,000 in fiscal 2007, compared with 815,000 in fiscal
2006, and ounces sold were 118,692 in fiscal 2007, compared with 128,849 in fiscal 2006. The
increase in tons was due to better efficiencies in the mining operations in the lower grade
pillars. The decrease in ounces was due to a slightly lower recovered grade. Recovered grade was
0.141 in fiscal 2007, compared with 0.158 in fiscal 2006, which is the result of payshoot
variability that impacts on grade as a result of sequential mining. The shaft also started to hoist
waste with reef that dilutes the quality of the ore. Of the 842,000 tons in Fiscal 2007, 93,000
were waste.
The increase in cash costs from $348 per ounce in fiscal 2006 to $386 per ounce in fiscal 2007 was
attributable primarily due to the decrease in the recovery grade that impacted negatively on gold
production.
The total shaft hoisting capacity for Evander No. 8 shaft is 85,000 tons per month. The average
tons milled in fiscal 2007 were 60,450 tons per month, Evander 8 only hoists to 15 level, from
which the ore is cross trammed to Evander 7 to be hoisted in 7A shaft.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 13.6 million tons (2.5
million ounces) will be sufficient for Evander 8 shaft to maintain production until approximately
fiscal 2031. Any future changes to the assumptions upon which the reserves are based, as well as
any unforeseen events affecting production levels, could have a material effect on the expected
period of future operations.
Capital Expenditure: Harmony incurred approximately R79.5 million ($11.0 million) in capital
expenditures at Evander 8 in fiscal 2007, principally for underground declines. Harmony has
budgeted R65.5 million ($9.1 million at the closing rate at the balance sheet date) for capital
expenditures at the Evander 8 shaft in fiscal 2008, primarily for ongoing development and phases 6
and 7 of the No 2 decline and two ventilation bore holes.

Tons milled from Cooke 1 were 490,000 in fiscal 2006, compared with 520,000 in fiscal 2005,
and ounces sold were 80,495 in fiscal 2006, compared with 79,101 in fiscal 2005. The decrease in
tons milled was due to a change in mining mix during fiscal 2005 between pillars and conventional
mining areas. Performance was also disrupted by moving the milling process from Cooke plant to
Doornkop, which is a larger and more efficient plant. During fiscal 2006 the pillars accounted for
approximately 60% of the operations and delivered a much higher recovered grade than the
conventional mining areas, albeit at much lower volumes. The increase in ounces sold was primarily
due to the higher recovered grade (0.164 in fiscal 2006 compared to 0.152 in fiscal 2005).
Cash costs per ounce were $401 in fiscal 2006, compared with $393 in fiscal 2005. This increase was
attributable primarily to the change in mining mix, which constitutes a decrease in conventional
mining and an increase in the portion of pillar mining from old remnant areas. This pillar mining
is much more costly to undertake and high volumes are also not possible. In addition, there was a
7.5% depreciation of the Rand against the U.S. dollar during the year. See Operating and Financial
Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased
in fiscal 2006 by 5%, due primarily to lower production volumes, increases in the costs of labor
and supplies and the effect of inflation on supply contracts.
Tons milled from Cooke 1 were 426,000 in fiscal 2007, compared with 490,000 in fiscal 2006, and
ounces sold were 75,698 in fiscal 2007, compared with 80,495 in fiscal 2006. The decrease in tons
milled was due to a change in mining mix during fiscal 2007 due to the depletion of the
conventional mining areas. The decrease in ounces sold was primarily due to lower volumes. The
recovery grade increased from 0.164 in fiscal 2006 to 0.178 in fiscal 2007.

Cash costs per ounce of gold were $434 in fiscal 2007, compared with $401 in fiscal 2006. This
increase was attributable primarily to the change in mining mix, which constitutes a decrease in
conventional mining and an increase in the portion of pillar mining from old remnant areas. This
pillar mining is much more costly to undertake and high volumes are also not possible. The increase
was due primarily to lower production volumes, increases in the costs of labor and supplies and the
effect of inflation on supply contracts also negatively affected cash costs.
The hoisting capacity of the Cooke 1 shaft is 176,000 tons per month, though currently operating at
a rate of 35,583 tons per month in connection with the extraction of the pillars.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable underground ore reserves of 0.3
million tons (0.1 million ounces) will be sufficient for the Cooke 1 shaft to maintain production
until approximately fiscal 2008. Any future changes to the assumptions upon which the reserves are
based, as well as any unforeseen events affecting production levels, could have a material effect
on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R14.2 million ($1.9 million) in capital
expenditures at Cooke 1 shaft in fiscal 2007 for ongoing development and other abnormal expenditure
seen as capital. Harmony has budgeted R23.2 million ($3.2 million at the closing rate at the
balance sheet date) in fiscal 2008, mostly for ongoing development

Tons milled from Cooke 2 were 353,000 in fiscal 2006, compared with 403,000 in fiscal 2005,
and ounces sold were 59,836 in fiscal 2006, compared with 54,441 in fiscal 2005. The decrease in
tons milled was due to planned scaling down in operations at some
of the lower grade UE1A reef horizons, and the depletion of the underground sludge dams in
fiscal 2005. The recovered grade increased from 0.135 in fiscal 2005 to 0.170 in fiscal 2006,
mainly as a result of replacing carbon areas with higher grade sources. As a result of the increase
in the recovered grade ounces sold also increased. Cash costs per ounce were $386 in fiscal 2006,
compared with $443 in fiscal 2005. This decrease in cash costs per ounce was attributable primarily
to the increased ounces sold. In addition, there was a 7.5% depreciation of the Rand against the
U.S. dollar during the year. See Operating and Financial Review and Prospects Exchange Rates.
If expressed in Rand terms, costs per ounce have decreased in fiscal 2006 by 10%.
Tons milled from Cooke 2 were 385,000 in fiscal 2007, compared with 353,000 in fiscal 2006, and
ounces sold were 57,215 in fiscal 2007, compared with 59,836 in fiscal 2006. The increase in tons
milled was due to an increase in production from the 79 level VCR project. The recovered grade
decreased from 0.170 in fiscal 2006 to 0.149 in fiscal 2007.
Cash costs per ounce of gold were $610 in fiscal 2007, compared with $386 in fiscal 2006. This
increase in cash costs per ounce was attributable primarily to the decrease in ounces produced,
combined with increases in the costs of labor and supplies and the effect of inflation on supply
contracts.
The hoisting capacity of the Cooke 2 shaft is 187,000 tons per month. The average tons milled in
fiscal 2007 was 32,965 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable underground ore reserves of 0.8
million tons (0.2 million ounces) will be sufficient for the Cooke 2 shaft to maintain production
until approximately fiscal 2009. Any future changes to the assumptions upon which the reserves are
based, as well as any unforeseen events affecting production levels, could have a material effect
on the expected period of future operations.

Capital Expenditure: Harmony incurred approximately R26.5 million ($3.7 million) in capital
expenditures at Cooke 2 in fiscal 2007 primarily for ongoing development. Harmony has budgeted R11
million ($1.5 million at the closing rate at the balance sheet date) in fiscal 2008, primarily for
ongoing development.

Tons milled from Cooke 3 were 652,000 in fiscal 2006, compared with 740,000 in fiscal 2005.
The decrease in tons milled was due to planned reduction of operations following the gradual
depletion of current trackless mining workplaces, and a shift in the mining mix towards pillar
mining operations from old remnant areas. The increase in recovered grade in 2006 was due to an
increased percentage of pillar mining. Even though the recovered grade increased slightly from
0.157 in fiscal 2005 to 0.161 in fiscal 2006, ounces sold decreased to 104,758 in fiscal 2006,
compared with 116,300 in fiscal 2005, primarily due to the decrease in tons milled.
Cash costs per ounce were $395 in fiscal 2006, compared with $364 in fiscal 2005. This
increase was due to the decrease in ounces produced, combined with the decrease in trackless mining
operations, which is a more cost effective method, and the move towards more expensive pillar
mining. In addition, there was a 7.5% depreciation of the Rand against the U.S. dollar during the
year. See Operating and Financial Review and Prospects Exchange Rates. If expressed in Rand
terms, costs per ounce have increased in fiscal 2006, due primarily to the lower volumes produced,
as well as increases in the costs of labor and supplies and the effect of inflation on supply
contracts.
Tons milled from Cooke 3 were 622,000 in fiscal 2007, compared with 652,000 in fiscal 2006. The
decrease in tons milled was due to the decrease in square meters. Square meters are down due to
panels being stopped because of low grades. The decrease in recovered grade in 2007, from 0.161 in
2006 to 0.147 ounces per ton in 2007, was due to lower volumes from the high grade VCR and changes
in the mining mix. Ounces sold decreased to 91,332 in fiscal 2007, compared with 104,758 in fiscal
2006, primarily due to the decrease in tons milled and recovery grade.
Cash costs per ounce of gold were $483 in fiscal 2007, compared with $395 in fiscal 2006. The
increase is due to the decrease in ounces produced, combined with increases in the costs of labor
and supplies and the effect of inflation on supply contracts.
The hoisting capacity of the Cooke 3 shaft is 265,000 tons per month. The average tons milled in
fiscal 2007 was 57,210 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable underground ore reserves of 5.2
million tons (1.0 million ounces) will be sufficient for the Cooke 3 shaft to maintain production
until approximately fiscal 2019. Any future changes to the assumptions upon which the reserves are
based, as well as any unforeseen events affecting production levels, could have a material effect
on the expected period of future operations.
Capital Expenditure: Harmony incurred R97.8 million ($13.6 million) in capital expenditures at the
Cooke 3 shaft in fiscal 2007, primarily on accessing the reserves in the 128 South Area as well as
for ongoing development. Harmony has budgeted R111.7 million ($15.5 million) calculated at the
closing rate at balance sheet date, for capital expenditures at the Cooke 3 shaft in fiscal 2008,
primarily for the 128 South development.

Tons milled from Leveraged Assets decreased to 5,122,000 in fiscal 2006, compared with 5,958,000 in
fiscal 2005. Volumes were negatively affected, mainly as a result of days lost to the industry
(through the wage strike in the first quarter and the Cosatu strike in the fourth quarter) and
lower underground volumes due to the closing down of Kudu/Sable, Nyala, Welkom 1 and St. Helena
shafts. Ounces sold decreased to 683,450 in fiscal 2006, compared with 841,280 in fiscal 2005,
primarily due to the decrease in tons milled. The recovered grade decreased from 0.140 in fiscal
2005 to 0.133 in fiscal 2006.
Tons milled from Leveraged assets increased to 5,507,000 in fiscal 2007, compared with 5,122,000 in
fiscal 2006. Ounces sold increase to 687,499 in fiscal 2007, compared with 683,450 in fiscal 2006.
The recovered grade decreased from 0.133 in fiscal 2006 to 0.125 in fiscal 2007.
Gold sales increased from $361.2 million in fiscal 2006 to $438.3 million in fiscal 2007, as a
result of the higher average gold price received during the year as well as an increase in ounces
sold. Cash costs for the Leveraged assets were $549 per ounce of gold in fiscal 2007, compared with
$493 per ounce of gold in fiscal 2006. This increase was due primarily to increases in the costs of
labor and supplies and the effect of inflation on supply contracts.

Tons milled from the Bambanani shaft increased to 1,196,000 in fiscal 2006, compared with
1,090,000 in fiscal 2005. Fires affected six months production in fiscal 2005 and three months of
the 2006 fiscal year. Ounces sold were 175,214 in fiscal 2006, compared with 197,535 in fiscal
2005. This decrease was due to the decrease in the recovered grade, which decreased from 0.181 in
fiscal 2005 to 0.147 in fiscal 2006.
Cash costs for Bambanani were $87.0 million in fiscal 2006, compared with $83.3 million in
fiscal 2005. Cash costs per ounce increased to $497 in fiscal 2006, compared with $422 in fiscal
2005, primarily due to the decrease in ounces produced. In addition, there was a 7.5% depreciation
of the Rand against the U.S. dollar during the year. See Operating and Financial Review and
Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased by 21%
in fiscal 2006, due primarily to lower production volumes, increases in the costs of labor and
supplies and the effect of inflation on supply contracts.
65
Tons milled from the Bambanani shaft decreased to 1,191,000 in 2007 compared with 1,196,000 in
fiscal 2006. An underground fire in March 2007 resulted in production loss of 4,180 ounces in
fiscal 2007. Ounces sold were 189,683 in fiscal 2007, compared with 175,214 in fiscal 2006. This
increase was due to the recovered grade, which increased from 0.147 in fiscal 2006 to 0.159 in
fiscal 2007.
Cash costs for Bambanani were $567 in fiscal 2007, compared with $497 in fiscal 2006. The costs per
ounce increased by 14% in fiscal 2007, due primarily to increases in the costs of labor and
supplies and the effect of inflation on supply contracts.
The rock hoisting capacity at Bambanani is 116,000 tons per month. The average tons milled in
fiscal 2007 was 90,106 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 9.3 million tons (2.0
million ounces) will be sufficient for Bambanani to maintain underground production until
approximately 2016. Any future changes to the assumptions upon which the ore reserves are based, as
well as any unforeseen events affecting production levels, could have a material effect on the
expected period of future operations.
Capital Expenditure: Harmony incurred approximately R119.8 million ($16.6 million) in capital
expenditures at Bambanani in the fiscal year ended June 30, 2007, primarily for ongoing
development. The below 103 level and De Bron Margin exploration program was terminated in August
2006 at an expenditure of R21.8 million ($3.0 million). Harmony has budgeted R141.4 million ($19.6
million at the closing rate at balance sheet date) for capital expenditures in fiscal 2008, for
ongoing development, the new orepass system and upgrading of the No. 3 cooling tower and fan and
abnormal expenditures.

Tons milled from Joel decreased to 436,000 in fiscal 2006, compared with 498,000 in fiscal
2005, attributable primarily to delays in commissioning of the midshaft loading arrangement on 137
level, which was only commissioned on February 28, 2006. Ounces sold were 58,595 in fiscal 2006,
compared with 64,464 in fiscal 2005. Even though the recovered grade improved, the positive
influence on
66
ounces sold was diluted due to the decrease in tons milled. Recovered grade improved
to 0.134 in fiscal 2006 compared with 0.129 in fiscal 2005.
Cash costs for Joel increased marginally to $29.2 million in fiscal 2006, compared with
$29.0 million in fiscal 2005. This increase was primarily attributed to lower production volumes
and increased contractor costs as contractors were utilized to do vamping of old areas. Cash costs
per ounce were $498 in fiscal 2006, compared with $450 in fiscal 2005. In addition, there was a
7.5% depreciation of the Rand against the U.S. dollar during the year. See Operating and Financial
Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased
by 14% in fiscal 2006, due primarily to lower production volumes, increases in the costs of labor
and supplies and the effect of inflation on supply contracts.
Tons milled from Joel shaft increased to 504,000 in fiscal 2007, compared with 436,000 in fiscal
2006, attributable primarily to the commissioning of the midshaft loading arrangement on 137 level.
Tons milled were negatively influenced in fiscal 2007 due to ceasing hoisting operations at North
Shaft on March 15, 2007 for the sinking stage removal, guide rope installation and the installation
of a proper spillage arrangement at shaft bottom. Ounces sold were 79,923 in fiscal 2007, compared
with 58,595 in fiscal 2006. The improved recovered grade and the increased tons positively
influenced ounces sold. Recovered grade improved to 0.158 in fiscal 2007 compared with 0.134 in
fiscal 2006.
Cash costs for Joel increased to $33.4 million in fiscal 2007, compared with $29.1 million in
fiscal 2006. This increase was primarily attributed to higher production volumes and increased
labor costs to support the build up in production. Cash costs per ounce were $418 in fiscal 2007,
compared with $498 in fiscal 2006. This decrease was primarily attributable to the higher
production levels and an increased grade.
The rock hoisting capacity at Joel is 180,000 tons per month. The average tons milled in fiscal
2007 was 42,083 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 4.1 million tons (0.6
million ounces) will be sufficient for Joel to maintain underground production until approximately
2015. Any future changes to the assumptions upon which the ore reserves are based, as well as any
unforeseen events affecting production levels, could have a material effect on the expected period
of future operations.
Capital Expenditure: Harmony incurred approximately R28. 2 million ($3.9 million) in capital
expenditures at Joel in the fiscal year ended June 30, 2007, on development on 129 level, general
replacement, maintenance and ongoing development and has budgeted R29.0 million ($4.0 million at
the closing rate at balance sheet date) for capital expenditures in fiscal 2008, primarily for
ongoing development and 129 Level Development.

Tons milled from Kudu/Sable were 13,000 in fiscal 2006, compared with 194,000 in fiscal 2005. The
decrease was primarily the result of the decision to close down the shaft in fiscal 2005. Ounces
sold were 2,024 in fiscal 2006, compared with 25,175 in fiscal 2005. The decrease in ounces sold is
primarily attributed to the decrease in tons milled. The recovered grade increased to 0.156 in
fiscal 2006, compared with 0.130 in fiscal 2005.
Cash costs for Kudu/Sable were $895,000 in fiscal 2006, compared with $18.9 million in fiscal 2005.
This decrease was primarily attributed to the substantially lower production levels and the
decision to close the shaft. Cash costs per ounce were $442 in fiscal 2006, compared with $750 in
fiscal 2005 primarily due to reduced volumes. In addition, there was a 7.5% depreciation of the
Rand
67
against the US dollar during the year. See Item 5. Operating and Financial Review and
Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have decreased in fiscal
2006 by 39%, due primarily to lower production volumes.
Tons milled from Kudu/Sable were 15,000 in fiscal 2007, compared with 13,000 in fiscal 2006. Ounces
sold were 845 in fiscal 2007, compared with 2,024 in fiscal 2006. The recovered grade decreased to
0.053 in fiscal 2007, compared with 0.156 in fiscal 2006. Cash costs per ounce decreased in fiscal
2007 to $224 from $442 in fiscal 2006, mainly due to the shaft being in clean up and closure mode.
Capital expenditure: No capital expenditure was incurred during fiscal 2007. No capital expenditure
has been budgeted for fiscal 2008.

A decision to close West shaft was taken and mining was stopped in December 2006, reclamation and
mud loading commenced in January 2007. The employees were transferred to Bambanani Shaft from
October 2006 to February 2007.
Tons milled from the West shaft were 206,000 in fiscal 2006, compared with 176,000 in fiscal 2005.
The increase was primarily due to high levels of reef stripping during the year to access higher
grade areas. Ounces sold were 25,525 in fiscal 2006, compared with 28,165 in fiscal 2005. The
decrease in ounces sold is primarily attributed to the lower recovered grade which is directly
related to the level of reef stripping being done The recovered grade decreased to 0.124 in fiscal
2006, compared with 0.160 in fiscal 2005, primarily due to the reef stripping at lower grades to
get back into higher grade pillars.
Cash costs for the West shaft were $13.7 million in fiscal 2006, compared with $12.9 million in
fiscal 2005. This increase was primarily attributed to increased production. Cash costs per ounce
were $535 in fiscal 2006, compared with $458 in fiscal 2005. This increase in cash costs per ounce
was attributable primarily to the lower level of gold produced. In addition, there was a 7.5%
depreciation of the Rand against the US dollar during the year. See Item 5. Operating and
Financial Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have
increased in fiscal 2006 by 20%, due primarily to lower production volumes, increases in the costs
of labor and supplies and the effect of inflation on supply contracts.
Tons milled from the West shaft were 93,000 in fiscal 2007, compared with 206,000 in 2006. The
decrease was primarily due to placing the shaft on care and maintenance in March 2007. Ounces sold
were 7,377 in fiscal 2007, compared with 25,525 in fiscal 2006. The decrease in ounces sold is
primarily attributed to the lower recovered grade and placing the shaft on care and maintenance.
The recovered grade decreased to 0.080 in fiscal 2007, compared with 0.124 in fiscal 2006,
primarily due to the reef stripping at lower grades to get back into higher grade pillars.
Cash costs for the West shaft were $7.9 million in fiscal 2007, compared with $13.7 million in
fiscal 2006. This decrease was primarily attributed to placing the shaft on care and maintenance.
Cash costs per ounce were $1075 in fiscal 2007, compared with $535 in fiscal 2006. This increase in
cash costs per ounce was attributable primarily to the lower level of gold produced, tons milled
and grade recovered.
The rock hoisting capacity at the West shaft is 24,000 tons per month. The average tons milled in
fiscal 2007 was 10,000 tons per month.
68
No reserve was declared in 2007 for West shaft after the shaft was put on care and maintenance in
March 2007.
Capital Expenditure: Harmony incurred R4.8 million ($0.7 million) in capital expenditures at the
West shaft in fiscal 2007 primarily on ongoing development. No capital expenditure required for
2008 as shaft was placed on care and maintenance.

Due to the increased operating costs in dollar terms, the decision was taken to close the Nyala
shaft during the quarter ended March 31, 2005.
Tons milled from Nyala were 2,000 in fiscal 2006, compared with 198,000 in fiscal 2005. Ounces sold
were 184 in fiscal 2006, compared with 23,503 in fiscal 2005. This decrease in ounces sold is
primarily attributed to the decrease in tons milled and the lower recovery grade at Nyala as a
result of the closure of the shaft.
The cash costs for Nyalas underground operations were $226,000 in fiscal 2006, compared with $17.6
million in fiscal 2005. This decrease was primarily attributed to the lower production levels as a
result of the decision to close this shaft in fiscal 2005. Cash costs per ounce were $1,228 in
fiscal 2006, compared with $748 in fiscal 2005.
Capital expenditure: No capital expenditure was incurred during fiscal 2007. No capital expenditure
has been budgeted for 2008.

Based on the increased operating costs in dollar terms, the decision was taken to scale down the
Eland shaft, commencing during fiscal 2004. The downscaling was completed during fiscal 2005 and
the shaft was closed.
Tons milled from the Eland shaft were 21,000 in fiscal 2006, compared with 175,000 in fiscal 2005.
The decrease in tons milled is primarily attributed to the decision to down scale the shaft and
then close it, with the small amount of production coming from clean-
up activities. Ounces sold decreased to 4,058 in fiscal 2006, compared with 26,782 in fiscal 2005,
due to the decrease in tons milled. There was an increase in the grade recovered from 0.153 in
fiscal 2005 to 0.193 in fiscal 2006.
69
Cash costs for the Eland shaft were $1.1 million in fiscal 2006, compared with $13.4 million in
fiscal 2005. This decrease was primarily attributed to the downscaling of the operation. In
addition, there was a 7.5% depreciation of the Rand against the US dollar during the year. See Item
5. Operating and Financial Review and Prospects Exchange Rates. If expressed in Rand terms,
costs per ounce have decreased in fiscal 2006 by 46%, due primarily to lower production volumes.
Tons milled from the Eland shaft were 11,000 in fiscal 2007, compared with 21,000 in fiscal 2006.
The decrease in tons milled is primarily attributed to the decision to down scale the shaft and
then close it, with the small amount of production coming from clean-up activities. Ounces sold
decreased further to 2,420 in fiscal 2007, compared with 4,058 in fiscal 2006, due to the decrease
in tons milled. There was an increase in the grade recovered from 0.193 in fiscal 2006 to 0.229 in
fiscal 2007.
Capital Expenditure: Harmony incurred capital expenditures of $0.1 million at the Eland shaft in
fiscal 2007 and no capital expenditures are foreseen for fiscal 2008.

Cash costs for St. Helena were $10.8 million in fiscal 2006, compared with $24.2 million in fiscal
2005. This decrease was primarily attributed to the reduction in tonnage milled and the lower
recovered grade. Cash costs per ounce were $845 in fiscal 2006, compared with $807 in fiscal 2005.
In addition, there was a 7.5% depreciation of the Rand against the U.S. dollar during the year. See
Operating and Financial Review and Prospects Exchange Rates. If expressed in Rand terms, costs
per ounce have increased in fiscal 2006 by 8%, due primarily to lower production volumes, increases
in the costs of labor and supplies and the effect of inflation on supply contracts.
Tons milled from St. Helena were 240,000 in fiscal 2007, compared with 127,000 in fiscal 2006. The
increase in tons milled was primarily due to the decision to consolidate 4 and 8 shafts into one
unit. Ounces sold were 21,319 in fiscal 2007, compared with
70
12,791 in fiscal 2006. The increase in
ounces sold is primarily attributed to the increase in tons milled. The recovered grade however
decreased to 0.089 during fiscal 2007, compared with 0.101 during fiscal 2006.
Cash costs for St. Helena were $17.9 million in fiscal 2007, compared with $10.8 million in fiscal
2007. This increase was primarily attributed to the increase in tonnage milled and square metres.
Cash costs per ounce were $840 in fiscal 2007, compared with $845 in fiscal 2006 due to the
increase in ounces produced.
The rock hoisting capacity at St. Helena is 63,000 tons per month. The average tons milled in
fiscal 2007 was 18,235 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 1.0 million tons (0.13
million ounces) will be sufficient for the St. Helena shaft to maintain underground production
until approximately 2012. Any future changes to the assumptions upon which the ore reserves are
based, as well as any unforeseen events affecting production levels, could have a material effect
on the expected period of future operations.
Capital Expenditure: Harmony incurred R10.4 million ($1.4 million) in capital expenditures at St.
Helena in fiscal 2007 and has budgeted R3.8 million ($527 thousands at the closing rate at balance
sheet date) for capital expenditures in fiscal 2008.

Tons milled from the Harmony 2 shaft increased to 598,000 in fiscal 2006, compared with 559,000 in
fiscal 2005, primarily due to an increase in the availability of mineable ground resulting from
development and equipping of areas identified by exploration drilling. Ounces sold were 69,446 in
fiscal 2006, compared with 68,547 in fiscal 2005. This increase is attributable primarily to the
increase in tons milled. Recovered grade was 0.116 in fiscal 2006, compared with 0.123 in fiscal
2005. This decrease in average grade is mainly attributable to a change in the mining mix between
the Basal and A-Reef during the year.
Cash costs were $33.5 million in fiscal 2006 compared with $30.0 million in fiscal 2005. Cash costs
per ounce were $483 in fiscal 2006 compared with $438 in fiscal 2005. This increase was
attributable primarily to increase in tonnage produced. In addition, there was a 7.5% depreciation
of the Rand against the U.S. dollar during the year. See Operating and Financial Review and
Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased in fiscal
2006 by 14%, due primarily to lower production volumes, increases in the costs of labor and
supplies and the effect of inflation on supply contracts.
Tons milled from the Harmony 2 shaft decreased to 516,000 in fiscal 2007, compared with 598,000 in
fiscal 2006, primarily due to an underground fire experienced at Harmony 2 in the Basal pillar.
Ounces sold were 46,274 in fiscal 2007, compared with 69,446 in fiscal 2006. This decrease is
attributable primarily to the fire in the high grade basal pillar area. Recovered grade was 0.090
in fiscal 2007, compared with 0.116 in fiscal 2006. This decrease in average grade is mainly
attributable to the fire in the high grade basal pillar area.
Cash costs were $29. 8 million in fiscal 2007 compared with $33.5 million in fiscal 2006. Cash
costs per ounce were $646 in fiscal 2007 compared with $483 in fiscal 2006. Although the total
costs are lower than the previous year, it includes approximately R3.1m ($433,687) in terms of
costs to fight the fire and replace critical items lost in the fire. The cash cost per ounce is
higher due to the loss of production in the higher grade basal pillars combined with the additional
costs of the fire.
The rock hoisting capacity at the Harmony 2 shaft is 54,000 tons per month. The average tons milled
in fiscal 2007 were 39,166 tons per month.
71
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 1.0 million tons (0.1
million ounces) will be sufficient for Harmony 2 to maintain underground production until
approximately fiscal 2010. Any future changes to the assumptions upon which the reserves are based,
as well as any unforeseen events affecting production levels, could have a material effect on the
expected period of future operations.
Capital Expenditure: Harmony incurred R35.3 million ($4.9 million) on capital expenditures at
Harmony 2 in fiscal 2007, primarily for ongoing capital development. Harmony has budgeted R30.1
million ($4.2 million at the closing rate at balance sheet date) for capital expenditures in fiscal
2008, primarily for ongoing development

Tons milled from Merriespruit 1 were 410,000 in fiscal 2006, compared with 414,000 in fiscal 2005.
Volumes were negatively affected, mainly as a result of days lost to the industry (through the wage
strike in the first quarter and the Cosatu strike in the fourth quarter). Ounces sold increased to
48,069 in fiscal 2006, compared with 45,559 in fiscal 2005, attributable primarily to the slightly
higher recovered grade. Recovered grade was 0.117 in fiscal 2006, compared with 0.110 in fiscal
2005. This increase was due to the increase in the mine call factor from 69% to 70%. Cash costs
were $24.1 million in fiscal 2006 compared with $21.7 million in fiscal 2005. This increase was
attributable primarily to an increase in labor cost. Cash costs per ounce were $501 in fiscal 2006
compared with $477 in fiscal 2005. This increase was attributable primarily to the increased labor
costs. In addition, there was a 7.5% depreciation of the Rand against the U.S. dollar during the
year. See Operating and Financial Review and Prospects Exchange Rates. If expressed in Rand
terms, costs per ounce have increased in fiscal 2006 by 8%, due primarily to increases in the costs
of labor and supplies and the effect of inflation on supply contracts.
Tons milled from Merriespruit 1 were 476,000 in fiscal 2007, compared with 410,000 in fiscal 2006.
Volumes increased, mainly as a result of being able to commence mining in the shaft pillar area,
after completion of the shaft tower installation project. Equipping and development was enhanced
enabeling entry to panels at an increased rate. Ounces sold increased to 50,612 in fiscal 2007,
compared with 48,069 in fiscal 2006, attributable primarily to the increased tonnage and the
recovered grade remaining at similar levels. Recovered grade was 0.106 in fiscal 2007, compared
with 0.117 in fiscal 2006. This slight decrease was mainly due to the erratic grade of the Middle
reef.
Cash costs were $26.7 million in fiscal 2007 compared with $24.1 million in fiscal 2006. This
increase was attributable primarily to an increase in labor cost and additional support required
in the shaft pillar area. Cash costs per ounce were $524 in fiscal 2007 compared with $501 in
fiscal 2006. This increase was attributable primarily to the increased labor costs and the
additional support costs in the shaft pillar area.
The rock hoisting capacity at the Merriespruit 1 shaft is 38,000 tons per month. The average tons
milled in fiscal 2007 was 36,083 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 1.7 million tons (0.2
million ounces) will be sufficient for Merriespruit 1 shaft to maintain
underground production until approximately fiscal 2013. Any future changes to the assumptions upon
which the reserves are based, as well as any unforeseen events affecting production levels, could
have a material effect on the expected period of future operations.

Capital Expenditure: Harmony incurred R25.3 million ($3.5 million) on capital expenditures at
Merriespruit 1 in fiscal 2007, primarily on ongoing development and has budgeted R26.9 million
($3.7 million at the closing rate at balance sheet date) for capital expenditures in fiscal 2008,
primarily for ongoing development.

Tons milled from the Merriespruit 3 shaft decreased to 452,000 in fiscal 2006, compared with
548,000 in fiscal 2005, primarily due to the availability of replacement ground. Ounces sold were
43,691 in fiscal 2006, compared with 54,690 in fiscal 2005. The decrease in ounces sold is
primarily attributed to the slightly lower recovery grade and the decrease in tons milled.
Recovered grade was 0.097 in fiscal 2006, compared with 0.100 in fiscal 2005.
Cash costs were $24.2 million in fiscal 2006 compared with $24.4 million in fiscal 2005. This
decrease was attributable primarily to the lower production levels. Cash costs per ounce were $554
in fiscal 2006 compared with $446 in fiscal 2005. This increase was attributable primarily to lower
production levels, and a lower grade. In addition, there was a 7.5% depreciation of the Rand
against the U.S. dollar during the year. See Operating and Financial Review and Prospects
Exchange Rates. If expressed in Rand terms, costs per ounce have increased in fiscal 2006 by 28%,
due primarily to lower production volumes, increases in the costs of labor and supplies and the
effect of inflation on supply contracts.
Tons milled from the Merriespruit 3 shaft decreased to 444,000 in fiscal 2007, compared with

Cash costs were $25.0 million in fiscal 2007 compared with $24.2 million in fiscal 2006. Cash
costs per ounce were $575 in fiscal 2007 compared with $554 in fiscal 2006. This increase in costs
is mainly attributable to increased labor rates and inflationary escalations.
The rock hoisting capacity at the Merriespruit 3 shaft is 48,000 tons per month. The average tons
milled in fiscal 2007 was 33,645 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 1.1 million tons (0.2
million ounces) will be sufficient for the Free State operations to maintain underground production
until approximately fiscal 2010. Any future changes to the assumptions upon which the reserves are
based, as well as any unforeseen events affecting production levels, could have a material effect
on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R24.6 million ($3.4 million) in capital
expenditures at the Merriespruit 3 shaft in fiscal 2007, principally for ongoing development and
has budgeted R29.8 million ($4.1 million at the closing rate at balance sheet date) for capital
expenditures in fiscal 2008, primarily for ongoing development.

Tons milled from Unisel were 500,000 in fiscal 2006, compared with 494,000 in fiscal 2005. The
increase was due to improved blasting frequency. Ounces sold increased to 72,963 in fiscal 2006,
compared with 65,011 in fiscal 2005, primarily because of the increase in tons milled and an
improved recovery grade. Recovered grade was 0.146 in fiscal 2006, compared with 0.132 in fiscal
2005. The higher grade was due to better than expected grades from the Middle Reef.
Cash costs were $28.8 million in fiscal 2006 compared with $31.1 million in fiscal 2005. This
decrease was attributable to benefits of the restructuring of the shaft in fiscal 2005. Cash costs
per ounce were $395 in fiscal 2006 compared with $478 in fiscal 2005. This decrease was
attributable primarily to the positive effect of the restructuring of the shaft in fiscal 2005 and
the increase in the recovered grade. In addition, there was a 7.5% depreciation of the Rand against
the U.S. dollar during the year. See Operating and Financial Review and Prospects Exchange
Rates. If expressed in Rand terms, costs per ounce have decreased in fiscal 2006 by 15%.
Tons milled from Unisel were 614,000 in fiscal 2007, compared with 500,000 in fiscal 2006. The
increase was due to improved blasting frequency. Ounces sold increased to 79,992 in fiscal 2007,
compared with 72,963 in fiscal 2006, primarily because of the increase in tons milled. Recovered
grade was 0.130 in fiscal 2007, compared with 0.146 in fiscal 2006
Cash costs were $35.0 million in fiscal 2007 compared with $28.8 million in fiscal 2006. This
increase was attributable to the extra production, upgrade of the refrigeration plant and
infrastructure. Cash costs per ounce were $438 in fiscal 2007 compared with $395 in fiscal 2006,
primarily due to the increased labor costs and inflationary pressure on supply costs.
The rock hoisting capacity at Unisel is 70,000 tons per month. The average tons milled in fiscal
2007 was 46,621 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 4.3 million tons (0.7
million ounces) will be sufficient for Unisel to maintain underground production until
approximately fiscal 2015. Any future changes to the assumptions upon which the reserves are based,
as well as any unforeseen events affecting production levels, could have a material effect on the
expected period of future operations
Capital Expenditure: Harmony incurred R39.1 million ($5.4 million) in capital expenditures at
Unisel in fiscal 2007, primarily on ongoing development and has budgeted R39.4 million ($5.4
million at the closing rate at balance sheet date) for capital expenditures in fiscal 2008,
primarily for ongoing development.

Tons milled from the Brand 3 shaft were 405,000 in fiscal 2006, compared with 448,000 in fiscal
2005. The decrease in tons was primarily due to the restructuring process at this shaft from July
to September 2005. Ounces sold were 41,647 in fiscal 2006, compared with 46,299 in fiscal 2005,
primarily because of the decrease in tons milled due to selective mining and fewer high grade basal
pillars being mined. Recovered grade was 0.103 in fiscal 2006, compared with 0.103 in fiscal 2005.
Cash costs were $23.3 million in fiscal 2006 compared with $22.9 million in fiscal 2005. This
increase was attributable primarily to the annual labor increases. Cash costs per ounce were $559
in fiscal 2006 compared with $494 in fiscal 2005. This increase was attributable primarily to lower
production and lower grade mined. In addition, there was a 7.5% depreciation of the Rand against
the U.S. dollar during the year. See Operating and Financial Review and Prospects Exchange
Rates. If expressed in Rand terms, costs per ounce have increased in fiscal 2006 by 16%, due
primarily to lower production volumes, increases in the costs of labor and supplies and the effect
of inflation on supply contracts.
Tons milled from the Brand 3 shaft increased to 444,000 in fiscal 2007 from 405,000 in fiscal 2006.
Ounces sold were 45,611 in fiscal 2007, compared with 41,647 in fiscal 2006, primarily because of
the improvement in tons milled. Recovered grade remained constant at 0.103.
Cash costs were $27.8 million in fiscal 2007 compared with $23.3 million in fiscal 2006. This
increase was attributable primarily to the bringing in of labor earlier to prepare for increase in
production in fiscal 2008, and also the upgrade of rail infrastructure on 40 and 46 levels. Cash
costs per ounce were $609 in fiscal 2007 compared with $559 in fiscal 2006. This increase was also
attributable primarily to the rail infrastructure upgrade and new labor brought in to prepare for
2008 fiscal increase in production.
The rock hoisting capacity at the Brand 3 shaft is 45,000 tons per month. The average tons milled
in fiscal 2007 was 33,742 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 0.7 million tons
(0.008 million ounces) will be sufficient for the Brand 3 operations to maintain underground
production until approximately the end of fiscal 2009. Any future changes to the assumptions upon
which the reserves are based, as well as any unforeseen events affecting production levels, could
have a material effect on the expected period of future operations.
Capital Expenditure: Harmony incurred R11.4 million ($1.6 million) on capital expenditures at Brand
3 in fiscal 2007.

The Brand 5 shaft was placed on care and maintenance during the quarter ended September 30, 2003,
this will remain in place until market conditions are more favorable or more economical parts of
the orebody are discovered.
The few tons milled during 2006 and 2007 were due to vamping of mud while cleaning the underground
dams. Water is pumped on the shaft and the dams are cleared and cleaned periodically.

Capital Expenditure: Harmony incurred no capital expenditures at Brand 5 in fiscal 2007 and no
capital expenditures are foreseen for fiscal 2008.

Tons milled from the Orkney 2 shaft were 347,000 in fiscal 2006, compared with 413,000 in fiscal
2005. The decrease in tons milled was primarily due to seismic events in August 2005 resulting in
the loss of face length flexibility and volume. Ounces sold were 69,877 in fiscal 2006, compared
with 78,449 in fiscal 2005. The decrease in ounces sold is primarily attributed to the lower
production, mainly due to the completion of the shaft pillar and other bigger pillars. Recovered
grade was 0.201 in fiscal 2006, compared with 0.190 in fiscal 2005.
Cash costs were $29.7 million in fiscal 2006 compared with $31.5 million in fiscal 2005. Cash costs
per ounce were $425 in fiscal 2006 compared with $401 in fiscal 2005. This increase was
attributable primarily to additional labor hours. In addition, there was a 7.5% depreciation of the
Rand against the U.S. dollar during the year. See Operating and Financial Review and Prospects
Exchange Rates. If expressed in Rand terms, costs per ounce have increased in fiscal 2006 by 9%,
due primarily to lower production volumes, increases in the costs of labor and supplies and the
effect of inflation on supply contracts.
Tons milled from the Orkney 2 shaft were 311,000 in fiscal 2007, compared with 347,000 in fiscal
2006. The decrease in tons milled was primarily due to seismic events resulting in the loss of face
length flexibility and volume. There was also a planned down scaling in production. Ounces sold
were 52,275 in fiscal 2007, compared with 69,877 in fiscal 2006. The decrease in ounces sold is
primarily attributed to the lower production. Recovered grade was 0.168 in fiscal 2007, compared
with 0.201 in fiscal 2006, due to a decrease in average mining grade.
Cash costs were $26.3 million in fiscal 2007 compared with $29.7 million in fiscal 2006. Cash costs
per ounce were $502 in fiscal 2007 compared with $425 in fiscal 2006. This increase was
attributable primarily due to lower production volumes, increases in the costs of labor and
supplies and the effect of inflation on supply contracts.
The rock hoisting capacity at the Orkney 2 shaft is 60,000 tons per month. The average tons milled
in fiscal 2007 were 23,593 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable reserves of 308,000 tons (86,132
ounces) will be sufficient for the Orkney 2 operations to maintain underground production until
approximately calendar year 2009. Any further changes to the assumptions upon which the ore
reserves are based, as well as any unforeseen events affecting the production levels, could have a
material effect on the expected period of future operations.
Capital Expenditure: Harmony incurred R30.8 million ($4.3 million) in on-going capital expenditures
at Orkney 2 in fiscal 2007 and has budgeted R36.5 million ($5.1 million at the closing rate at
balance sheet date) for capital expenditures in fiscal 2008, primarily for ongoing development.

Tons milled from the Orkney 4 shaft were 406,000 in fiscal 2006, compared with 455,000 in fiscal
2005. The decrease in tons milled was primarily due to shaft ore pass scaling and seismicity
experienced in the shaft pillar area. Ounces sold were 58,897 in fiscal 2006, compared with 76,971
in fiscal 2005. The decrease in ounces sold is primarily attributed to the decrease in production
and a decrease in the recovery grade. The decrease in recovered grade from 0.169 in fiscal 2005 to
0.145 in fiscal 2006 is mainly attributable to a switch in production as a result of seismicity
experienced from the higher grade shaft pillar to lower grade areas.
Cash costs were $29.3 million in fiscal 2006 compared with $29.6 million in fiscal 2005. This
decrease was attributable primarily to the lower production volumes. Cash costs per ounce were $497
in fiscal 2006 compared with $385 in fiscal 2005. This increase was mainly as a result of the
reduced volumes. In addition, there was a 7.5% depreciation of the Rand against the U.S. dollar
during the year. See Operating and Financial Review and Prospects Exchange Rates. If expressed
in Rand terms, costs per ounce have increased in fiscal 2006 by 33%, due primarily to lower
production volumes, increases in the costs of labor and supplies and the effect of inflation on
supply contracts.
Tons milled from the Orkney 4 shaft were 397,000 in fiscal 2007, compared with 406,000 in fiscal

and a decrease in the recovery grade.The decrease in recovered grade from 0.145 in fiscal 2006 to
0.116 in fiscal 2007 is mainly attributable to a change in mining mix as a result of seismicity
experienced from the higher grade shaft pillar to lower grade areas. There was also down scaling
of production in the shaft pillar area which resulted the mining of more remote areas.
Cash costs were $26.3 million in fiscal 2007 compared with $29.3 million in fiscal 2006. This
decrease was attributable primarily to the lower production volumes. Cash costs per ounce were $572

The rock hoisting capacity at the Orkney 4 shaft is 75,000 tons per month. The average tons milled
in fiscal 2007 were 30,041 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable reserves of 2,69 million tons (356,000
ounces) will be sufficient for the Orkney 4 operations to maintain underground production until
approximately calendar year 2013. Any further changes to the assumptions upon which the ore
reserves are based, as well as any unforeseen events affecting the production levels, could have a
material effect on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R36.7 million ($5.1 million) in ongoing capital
expenditures at Orkney 4 in the fiscal year ended June 30, 2007, and has budgeted R27.1 million
($3.76 million at the closing rate at balance sheet date) in fiscal 2008, primarily for ongoing
development.

During fiscal 2006, Harmony approved the re-opening of the shaft. The shaft started producing in
the first quarter of fiscal 2007.
77
Tons milled from the Orkney 7 shaft were 239,000 in fiscal 2007. Ounces sold were 20,668 in fiscal
2007. The recovered grade was 0.086 in fiscal 2007.
Cash costs were $11,942,000 in fiscal 2007. Cash costs per ounce were $578 in fiscal 2007.
The rock hoisting capacity at the Orkney 7 shaft is 60,000 tons per month. The average tons milled
in fiscal 2007 were 18,085 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable reserves of 2,8 million tons (387,000
ounces) will be sufficient for the Orkney 7 operations to maintain underground production until
approximately calendar year 2015. Any further changes to the assumptions upon which the ore
reserves are based, as well as any unforeseen events affecting the production levels, could have a
material effect on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R41.5 million ($5.8 million) on project capital
expenditures at Orkney 7 in the fiscal year ended June 30, 2007, and has budgeted R27.3 million
($3.79 million at the closing rate at balance sheet date) in fiscal 2008, primarily for project

Tons milled from Growth Assets decreased to 1,502,000 in fiscal 2006, compared with 1,545,000 in
fiscal 2005. Volumes were negatively affected, mainly as a result of days lost to the industry
(through the wage strike in the first quarter and the Cosatu strike in the fourth quarter) and as a
result of flexibility problems. Ounces sold decreased to 214,460 in fiscal 2005, compared with
260,066 in fiscal 2005, primarily due to the decrease in tons milled. Recovered grade decreased
from 0.168 in fiscal 2005 to 0.143 in fiscal 2006.
Cash costs per ounce for the Growth Assets were $530 in fiscal 2006, compared with $431 in fiscal
2005. This increase was mainly a result of the reduced volumes. In addition, there was a 7.5%
depreciation of the Rand against the U.S. dollar during the year. See Operating and Financial
Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased
in fiscal 2006 by 27%, due primarily to lower production volumes, increases in the costs of labor
and supplies and the effect of inflation on supply contracts.
Tons milled from Growth assets increased to 1,714,000 in fiscal 2007, compared with 1,502,000 in
fiscal 2006. Ounces sold increased to 252,074 in fiscal 2007, compared with 214,460 in fiscal 2006,
primarily due to the increase in tons milled. Recovered grade increased from 0.143 in fiscal 2006
to 0.147 in fiscal 2007.
Gold sales increased to $160.9 million in fiscal 2007, compared with $113.4 million in fiscal 2006
due primarily to the higher average gold price received in fiscal 2007. Cash costs for the Growth
assets decreased from $530 to $507 per ounce of gold in fiscal 2007.

Tons milled from the Elandsrand shaft were 987,000 in fiscal 2006, compared with 1,1019,000 in
fiscal 2005, and ounces sold were 170,867 in fiscal 2006, compared with 207,371 in fiscal 2005.
Volumes were negatively affected, mainly as a result of days lost to the industry (through the wage
strike in the first quarter and the Cosatu strike in the fourth quarter), and the continued lack of
flexibility in face length to deal with erratic face grades and seismicity. Recovered grade decline
during the second half of fiscal 2006 as a result of having to mill higher levels of waste rock
from February to May 2006, resulting in an average of 0.173 in fiscal 2006, comparing to the
average of 0.204 in fiscal 2005..
The reduction in ounces produced was the main contributor to the increase in cash cost from $427
per ounce in fiscal 2005 to $523 per ounce in fiscal 2006.
Tons milled from the Elandsrand shaft were 1,117,000 in fiscal 2007, compared with 987,000 in
fiscal 2006. Ounces sold increased to 194,710 in fiscal 2007, compared with 170,867 in fiscal 2006
as a result of the increased volumes in production. Mining continues in the old, upper areas of the
mine, while the new mine project is completed. Recovered grades increased during fiscal 2007,
resulting in an average of 0.174 in fiscal 2007, compared to the average of 0.173 in fiscal 2006.
The increase in labor rates and inflation were the main contributors to the increase in cash cost
from $523 per ounce in fiscal 2006 to $527 per ounce in fiscal 2007. Costs per ounce have increased
in fiscal 2007 by 1%, due primarily to increases in the costs of labor and supplies and the effect
of inflation on supply contracts.
Elandsrand currently operates one production shaft, with a current hoisting capacity of 190,000
tons per month which will be utilized to its full capacity, once the Elandsand New Mine Project is
complete. The average tons milled in fiscal 2007 was 84,783 tons per month.
On a simplistic basis, assuming no additional reserves are identified, at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 34.9 million tons (8.3
million ounces) will be sufficient for the Elandsrand shaft to maintain underground production
until approximately calendar year 2026. Any future changes to the assumptions upon which the ore
reserves are based, as well as any unforeseen events affecting production levels, could have a
material effect on the expected period of future operations
Elandsrand New Mine Project: The project, initiated by AngloGold Ashanti in 1991, was intended to
increase the life of mine by exploiting the southern portion of the lease area between 3,000
3,600 meters below surface. This will be achieved by deepening the sub-vertical and ventilation
shafts. During fiscal 2004, the payshoot, which was mined on the shallower levels of the old mine,
was exposed on levels 102 and 105. Production from level 102 started in January 2004.
Good progress was made with the project during the 2007 fiscal year, with all the targeted
milestones having been achieved. The project remains on schedule. Sinking of the No. 2 Service
Shaft, from 95 level down to 105 level, was completed without a single incident or accident.
Infrastructure fiscal 2007:
|
|
|
Sinking and equipping of the No 2 Service Shaft to its final depth (105 level) was
completed during the year. |
|
|
|
|
The 92 level turbine dam was sunk to its depth of 26m, and supported and sealed. |
|
|
|
|
The Man 1 Winder stations on the sub-shaft were commissioned on all five levels (102,
105, 109, 113 and 115). The sub-shaft can now hoist men and material with both winders on
the project levels. |
|
|
|
|
All the electrical main sub-stations on the project levels (except 115 level) have now
been completed and commissioned. This includes all main feeder cables below 100 level. All
the services cables have been installed from 100 level to 115 level. These are expected to
be commissioned during the first quarter of the 2008 fiscal year. |
|
|
|
|
The 22 kV systems from surface to 100 level was completed during the year and is
awaiting the installation of the 10 MVA transformer on 100 level. |
|
|
|
|
The installation of the No. 1 Settler was completed during the year and is planned to be
brought on line towards the end of December 2007. |
|
|
|
|
The winder and headgear chamber for the No 3 Service shaft was completed during the
year. |
In March 2007, 109 levels access development reached the end of project capital position and is
continuing on ongoing capital. A total of 738 meters was achieved.
80
Capital Expenditure: Harmony incurred approximately R238.2 million ($33.1 million) in capital
expenditures at the Elandsrand operations in fiscal 2007 mainly for the sub shaft deepening project
and ongoing development. Harmony has budgeted R389.7 million ($54.1 million, using the closing rate
at balance sheet date) for capital expenditures at the Elandsrand operations in fiscal 2008,
primarily for the sub shaft deepening project and ongoing development.

Tons milled from Doornkop shaft were 515,000 in fiscal 2006, compared with 526,000 in fiscal 2005.
Volumes were negatively affected mainly as a result of days lost to the industry (through the wage
strike in the first quarter and the cosatu strike in the fourth quarter). Ounces sold were 43,593
in fiscal 2006, compared 52,695 in fiscal 2005. The decrease in ounces sold was primarily due to
the lower recovery grade and decrease in tons milled. The recovered grade deteriorated to 0.085 in
fiscal 2006, compared with 0.100 in fiscal 2005, due to the depletion of certain high grade panels.
Cash costs per ounce of gold were $558 in fiscal 2006, compared with $447 in fiscal 2005. This
increase was attributable primarily to the lower production volumes and the lower recovered grade.
Tons milled from Doornkop shaft were 597,000 in fiscal 2007, compared with 515,000 in fiscal 2006.
Mining continues in the old, upper areas of the mine, while the new mine project is completed.
Volumes increased, mainly as a result of flexibility created during the year by increasing
development of the orebody. Ounces sold were 57,364 in fiscal 2007, compared with 43,593 in fiscal
2006. This increase in ounces sold was primarily due to the increase in recovered grade and
additional tons milled. The recovered grade improved to 0.096 in fiscal 2007, compared with 0.085
in fiscal 2006.
Cash costs per ounce of gold were $439 in fiscal 2007, compared with $558 in fiscal 2006. This
decrease was attributable primarily to the higher production volumes and the higher recovered
grade.
The hoisting capacity of the Doornkop shaft is 204,000 tons per month. The average tons milled in
fiscal 2007 were 49,692 tons per month.
On a simplistic basis, assuming no additional resource are identified, at expected production
levels, it is foreseen that the Doornkop shaft will maintain production until approximately fiscal
2017. Any future changes to the assumptions upon which the reserves are based, as well as any
unforeseen events affecting production levels, could have a material effect on the expected period
of future operations.
Doornkop South Reef Project: The project involves the deepening of the Doornkop mine shaft to
1,973m to mine the South Reef and includes development towards the mining areas. The South Reef
lies between 1,650m and 2,000m below surface. Shaft Sinking operations were completed during the
year. Equipping of the shaft continued and 192 level station was partially commissioned to support
the production that commenced on this level. The rock winder programme is progressing well. Winder
house preparations are completed and winder refurbishment is nearing completion. Development
continued on all levels with raiselines opening up on 192 level.
Capital Expenditure: Harmony incurred approximately R270.4 million ($37.6 million) in capital
expenditures at the Doornkop project in fiscal 2007, primarily for the expansion and deepening of
the shaft. Harmony has budgeted R214.8 million ($29.8 million) for capital expenditures at the
Doornkop South Reef project in fiscal 2008.

The expected capacity of the Phakisa shaft will be 126,766 tons per month. Phakisa has no rock
hoisting facilities and all rock will be transported via a Rail system on 55 level to the Nyala
mine for hoisting to surface.
On a simplistic basis reported proven and probable underground ore reserves of 22.0 million tons
(5.4 million ounces) will be sufficient for the Phakisa shaft to, once production commence,
maintain production until approximately fiscal 2027. Any future changes to the assumptions upon
which the reserves are based, as well as any unforeseen events affecting production levels, could
have a material effect on the expected period of future operations.
Phakisa Shaft Project: The project involves the establishment of infrastructure and the sinking and
equipping of a primary shaft to a depth of 2,427m below surface. Access development have commenced
on the five production levels (66, 69, 71, 73 and 75 Levels) and to date, in excess of 2000m
development have been achieved. 75 level will be host to a 1,500m, 9 degree twin decline, with
another five levels (77, 79, 81, 83 and 85) where access development will be done towards the reef
horizon. Development of the twin decline is expected to commence during 2008.
Good progress was achieved during the year, the main shaft equipping was completed and the rock
handling system on 77 Level was commissioned on August 20, 2006. Installation of the permanent
water handling systems (i.e., Settlers, Main Pump Station on 77 Level, Mud press and Underground
dams) have commenced and expected completion is April 2008. Construction has commenced on
ventilation cooling plants on 55 Level and will be completed in May 2008. The cooling systems of
Phakisa Shaft will include a first phase 10MW Ice Plant on surface. This will be a first in the
gold mining industry.
The Rail on 55 level was installed over the 5km and commissioned on April 10, 2007. Although
various commissioning challenges had to be negotiated, the Rail system has thus far proven to be a
cost effective ore handling system.
Capital Expenditure: Harmony incurred approximately R227.4 million ($31.6 million) in capital
expenditures at the Phakisa operations in the fiscal year ended June 30, 2007. Harmony has budgeted
Rand 186.6 million ($25.9 million at the closing rate at balance sheet date) for capital
expenditures in fiscal 2008, primarily for the establishing and development of the shaft.

Tons milled from surface operations cecrease to 3,984,000 in fiscal 2006, compared with 6,528,000
in fiscal 2005. Ounces sold decreased to 116,388 in fiscal 2006, compared with 188,904 in fiscal
2005, primarily due to the decrease in tons milled. Recovered grade remained constant at 0.029 in
fiscal 2006 from fiscal 2005.
Cash costs for the surface operations were $426 per ounce of gold in fiscal 2006, compared with
$390 per ounce of gold in fiscal 2005. This increase was mainly due to the significant decrease in
volumes produced.
Tons milled from surface operations increased to 5,451,000 in fiscal 2007, compared with 3,984,000
in fiscal 2006. Ounces sold decreased to 100,925 in fiscal 2007, compared with 116,388 in fiscal
2006, primarily due to a recovered grade. Recovered grade decreased to 0.019 in fiscal 2007
compared to 0.029 in fiscal 2006. The increase in tons milled and decrease in recovered grade can
primarily be attributed to the treatment of waste dumps which was started during fiscal 2007.
Gold sales increased to $65.4 million in fiscal 2007, compared with $59.8 million in fiscal 2006.
Cash costs for the surface operations were $404 per ounce of gold in fiscal 2007, compared with
$426 per ounce of gold in fiscal 2006.

Tons milled increased from 1,855,000 in fiscal 2005 to 2,008,000 in fiscal 2006. This increase was
due to the processing from strategic stockpiles while work in the D Zone was stopped. Ounces sold
decreased to 77,071 in fiscal 2006, compared with 108,195 in fiscal 2005, primarily due to the
lower recovered grade. The recovered grade decreased to 0.038 in fiscal 2006, compared with 0.058
in fiscal 2005. Due to unstable ground conditions on the eastern wall of the higher grade D Zone
pit, work was stopped in this section during the December quarter. Mining only continued in the
lower grade A Zone and from strategic stockpiles for the remainder of fiscal 2006, thus reducing
average recovered grade for the year.
Cash costs at Kalgold were $412 per ounce in fiscal 2006, compared with $373 per ounce in fiscal
2005. This increase was due to the lower production volumes.
Ounces sold decreased to 56,129 in fiscal 2007, compared with 77,071 in fiscal 2006, primarily due
to the lower recovered grade. Tons milled decreased from 2,008,000 in fiscal 2006 to 1,740,000 in
fiscal 2007. These decreases were due to lower throughput into the plant due to a water shortage
encountered in March 2007. Recovered grade decreased to 0.032 (ounces/ton) in fiscal 2007, compared
with 0.038 in fiscal 2006. Mining was stopped on the A Zone pit during the December 2006 quarter
for geotechnical reasons.
Cash costs at Kalgold were $485 per ounce in fiscal 2007, compared with $412 per ounce in fiscal
2006. This increase was due to the lower volumes produced.
83
The processing capacity of the Kalgold operation is 165,000 tons per month. The average tons milled
in fiscal 2007 were 132,485 tons per month.
Active use of heap leaching was discontinued in July 2001; however, Harmony expects to put the
material on the heap leach pad through the processing mills at the end of the life of mine to
recover the residual gold.
On a simplistic basis, assuming no additional reserves are identified and at expected production
levels, it is foreseen that the reported proven and probable ore reserves of 7.9 million tons (0.37
million ounces) will be sufficient for the Kalgold operations to maintain production until
approximately fiscal 2010. However, any future changes to the assumptions upon which the reserves
are based, as well as any unforeseen events affecting production levels, could have a material
effect on the expected period of future operations.
Capital Expenditure: Harmony incurred approximately R2.7 million ($0.4 million) in capital
expenditures at the Kalgold operations in the fiscal year ended June 30, 2007. Harmony has budgeted
R2.6 million ($0.4 million at the closing rate at balance sheet date) for capital expenditures in
fiscal 2008, primarily for exploration drilling.

Tons milled from surface operations continued to decrease to 336,000 in fiscal 2006, compared with
1,361,000 in fiscal 2005 due to the decision taken in fiscal 2004 to discontinue treating surface
sources as a result of the prevailing Rand gold price. Even though the recovered grade increased to
0.033 in fiscal 2006, compared with 0.027 in fiscal 2005, ounces sold decreased to 11,019 in fiscal
2006, compared with 36,420 in fiscal 2005, primarily due to the lower tons milled.
Cash costs were $5.4 million in fiscal 2006, compared with $15.4 million in fiscal 2005. Cash costs
per ounce were $489 in fiscal 2006, compared with $424 in fiscal 2005. If expressed in Rand terms,
costs per ounce have increased in fiscal 2006 by 19%, due primarily to lower production volumes,
increases in the costs of labor and supplies and the effect of inflation on supply contracts. In
addition, there was a 7.5% depreciation of the Rand against the U.S. dollar during the year. See
Operating and Financial Review and Prospects Exchange Rates.

Tons milled from the Free State surface operations were 897,000 in fiscal 2006, compared with
467,000 in fiscal 2005, primarily due to the conversion of Saaiplaas plant from a underground
treatment plant to a surface treatment plant. The recovered grade decreased to 0.018 in fiscal
2006, compared with 0.020 in fiscal 2005. Ounces sold increased to 15,902 in fiscal 2006, compared
with 9,542 in fiscal 2005, primarily due to the increase in tons milled.
Cash costs were $6.4 million in fiscal 2006, compared with $3.1 million in fiscal 2005. This
increase is attributable primarily to higher volumes being treated. Cash costs per ounce increased
during fiscal 2006 to $404 per ounce, compared with $348 in fiscal 2005. In addition, there was a
7.5% depreciation of the Rand against the U.S. dollar during the year. See Operating and Financial
Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased
in fiscal 2006 by 19%, due primarily to increases in the costs of labor and supplies and the effect
of inflation on supply contracts.
Tons treated from the Free State surface operations were 2,369,000 in fiscal 2007, compared with
897,000 in fiscal 2006, primarily due to Project Phoenix having been fully commissioned during the
year and now treating 500,000 tons per month tailings material. The recovered grade decreased to
0.009 in fiscal 2007, compared with 0.018 in fiscal 2006 as a result of an increase in slimes dam
reclamation. Ounces sold increased to 21,345 in fiscal 2007, compared with 15,902 in fiscal 2006,
primarily due to the increase in tons treated.
Cash costs were $6.4 million in fiscal 2007, compared with $6.4 million in fiscal 2006. Cash costs
per ounce decreased during fiscal 2007 to $304 per ounce, compared with $404 in fiscal 2006. Due to
the increase in ounces produced
Capital Expenditure: Harmony incurred approximately R33.9 million ($4.7 million) in capital
expenditures at the Free State operations in fiscal 2007. Harmony has no budgeted capital
expenditures for the Free State operations for fiscal 2008.

Tons milled from Randfonteins surface operations decreased to 539,000 in fiscal 2006, compared
with 2,757,000 in fiscal 2005, primarily due to plant capacity constraints as higher grade
underground materials were given preference. Ounces sold were 11,650 in fiscal 2006 compared with
33,397 in fiscal 2005. Recovered grade was 0.022 in fiscal 2006 compared with 0.012 in fiscal 2005.
In fiscal 2006, cash costs per ounce increased to $431 from $423 in fiscal 2005. This increase was
attributable primarily to the decreased production volumes. In addition, there was a 7.5%
depreciation of the Rand against the U.S. dollar during the year. See Operating and Financial
Review and Prospects Exchange Rates. If expressed in Rand terms, costs per ounce have increased
in fiscal 2006 by 5%, due primarily to lower production volumes, increases in the costs of labor
and supplies and the effect of inflation on supply contracts.
Currently, Randfonteins surface operations are focused on the recovery of gold from areas
previously involved in processing, including waste rock dumps and tailings sites (slimes and sand).
Tons milled from Randfonteins surface operations increased to 894,000 in fiscal 2007, compared
with 539,000 in fiscal 2006 mainly due to the recommissioning of the Cooke Plant to treat surface
sources. Ounces sold were 18,974 in fiscal 2007 compared with 11,650 in fiscal 2006. Recovered
grade was 0.021 in fiscal 2007 compared with 0.022 in fiscal 2006.
In fiscal 2007, cash costs decreased to $305 per ounce from $431 per ounce in fiscal 2006. This
decrease was attributable primarily to increased production volumes and the lower cost of treating
sand through the Cooke Plant.
Capital Expenditure: Harmony incurred approximately R52.3 million ($7.3 million) in capital
expenditures at the Randfontein operations in fiscal 2007, primarily on the upgrading of the
Doornkop plant and surface dump sampling. An estimated R65 million ($9.2 million) is expected to be
spent on converting the Cooke Plant to treat sand as well as to purchase land for an additional
tailings disposal site in fiscal 2008.

Tons milled from Targets surface operations increased to 204,000 in fiscal 2006 from 88,000 in
fiscal 2005. This increase was as a result of the strategic decision to utilize the Target Plant to
full capacity. The decrease in volumes from underground sources was compensated by the increase in
surface tons milled.
Tons milled from Targets surface operations decreased to 147,000 in fiscal 2007 from 204,000 in
fiscal 2006. This decrease was as a result of improved volumes from underground operations. Ounces
sold increased to 1,316 in fiscal 2007 compared to 746 in fiscal 2006, primarily as a result of the
substantial increase in recovered grade from 0.004 in fiscal 2006 to 0.009 in fiscal 2007.
In fiscal 2006, cash costs amounted to $1,298 per ounce, versus $781 in fiscal 2007.

Capital Expenditure: Harmony incurred approximately $1.7 million capital expenditures at the Target
surface operation in fiscal 2007. No capital expenditures are expected for fiscal 2008.
Harmony has two operational mines in Western Australia: the Mt. Magnet operations and the South
Kalgoorlie operations. These operations were acquired as part of the purchase of two Australian
gold mining companies: New Hampton, acquired in April 2001 and Hill 50 acquired in April 2002. The
New Hampton transaction included two operations in Western Australia, Big Bell in the Murchison
region (which ceased operation in July 2003 and its plant was sold in November 2003) and Jubilee in
the Eastern Goldfields near Kalgoorlie, two processing plants associated with these operations and
related exploration rights. The Hill 50
87
transaction included the Mt. Magnet operations in the Murchison region, the New Celebration
operations in the Eastern Goldfields near Kalgoorlie, two plants associated with these operations
and related exploration rights.
Each of our Australian operations conducts surface mining (principally through open pit methods)
and underground mining, with access through two declines at Mt. Magnet and one decline at South
Kalgoorlie. The Mt. Marion underground mine at South Kal Mine (SKM) ceased operating in June
2007. Open pit mining at South Kalgoorlie recommenced during fiscal 2007 with the start-up of the
Shirl and Hampton Boulder Jubilee (HBJ) open pit projects. Harmony uses mostly mechanized mining at
its Australian operations in comparison to the South African operations (excluding operations at
Target). Contractors conduct much of this mechanized mining. The contractors are responsible for
provision of the equipment and personnel needed for production of the ore under guidance of
Harmonys management. In fiscal 2007, Harmony commenced open pit mining at its operations with
leased equipment and its own personnel. As of June 30, 2007, Harmonys Australian operations had
229 employees and 426 contractor employees
Our Australian operations control exploration and mineral rights over a total area of approximately
325,088 hectares (803,310 acres), of which the active mining areas currently total approximately
196,794 hectares (486,289 acres).
In fiscal 2005, 2006 and 2007, the Australian operations accounted for approximately 10% of our
total gold sales.
Harmony has classified these assets as being available for sale as they do not fit Harmonys
strategy for operating large, long life mines and partly in response to a seismic event resulting
in a rockfall at the Hill 50 mine at Mt. Magnet during May 2007 after which decline development was
stopped. The event has impacted on the future life of this mine and its expected production
levels, and also had a negative financial impact on the carrying value of these assets.
In November 2007, Harmony announced that it signed a letter of intent with the Austrlian-based
junior miner Monarch Gold Mining Company (Monarch: ASX/DIFX:MON) for the sale of its Mt. Magnet
operations for A$65 million (US$57.2 million). The offer is
made up of a combination of A$30 million (US$26.4 million)
cash. A$20 million (US$17.6 million) in shares and
A$15 million (US$13.2 million) in convertible notes.
In July 2007 Harmony announced the sale of the South Kal Mine to Dioro Exploration NL. The
transaction is expected to be concluded during the December 2007 quarter. The transaction price
includes A$25 million (US$21.2 million) payable in cash to Harmony on completion and the issue of shares to the value
of A$20 million (US$17 million) to Harmony.
The table details the operating and production results from our Australian operations for fiscal
2007, 2006 and 2005:

Tons milled for the Australian operations were 3,398,000 in fiscal 2006 compared to 4,148,000, in
fiscal 2005. This decrease was primarily due to lower production from open pits at Mt. Magnet and
South Kalgoorlie Mines.Recovered grade from Australian operations was 0.068 for fiscal 2006
compared to 0.072 ounces per ton in fiscal 2005. This decrease was due to the treatment of
significant quantities of low grade stockpiles at South Kalgoorlie Mines during the year. Cash
costs per ounce for Australian operations were $419 in fiscal 2006, compared with $337 in fiscal
2005. This increase was due to higher underground and open pit contracting costs at both sites
during the year, as well as decreased gold production levels.
Tons milled from Australian operations were 3,266,000 in fiscal 2007, compared with 3,398,000 in
fiscal 2006. This decrease was primarily due to lower production from underground mines and surface
sources at Mt. Magnet. Recovered grade from Australian operations was 0.069 in fiscal 2007,
compared with 0.068 in fiscal 2006 which are mainly in-line with the previous fiscal year and are a
combination of higher grades from our South Kal mines and lower grades from the Mt. Magnet
operations. Cash costs for Australian
88
operations were $512 per ounce of gold in fiscal 2007, compared with $419 per ounce of gold in
fiscal 2006. This increase was due to higher underground and open pit contracting and labor cost at
both sites during the year, as well as decreased gold production levels.
Capital expenditure: Net capital expenditure amounted to $26.9 million in fiscal 2007
compared to $43.3 million in fiscal 2006. The majority of which relates to on-mine decline
development at Hill 50 (Mt Magnet) and Mt. Marion (South Kal) the new decline at the St. George
mine (Mt Magnet), and the pre strip for the HBJ Open Pit (South Kal)
Mt. Magnet Operations
Introduction. In 2002, Harmony acquired Mt. Magnet as part of the Hill 50 transaction. In fiscal
2005, 2006 and 2007, Mt. Magnets operations accounted for 6% of Harmonys total gold sales
History. Mining at Mt. Magnet began after the discovery of gold in 1896. From that time to
June 30, 2007, the Mt. Magnet area has produced approximately 5.74 million ounces. The current Mt.
Magnet operations commenced production in the late 1980s on the Hill 50 and Star underground mines
and nearby open pits, and the processing of low grade ore from previously accumulated stockpiles.
Production ceased at the Star underground mine in June 2005. The Star underground mine was
subsequently replaced by St. George, a new underground mine.
Geology. The Mt. Magnet operations are located near the town of Mt. Magnet in the Murchison
region, 560 kilometers northeast of Perth. The geology consists of folded basaltic and komatiitic
greenstones with intercalated banded iron formations and volcaniclastic units. In addition to
having been intensely folded, the area has undergone substantial faulting and later intrusion by
felsic intrusives. Mineralization within the Murchison belt consists of sulphide replacement style
(characteristic of the Hill 50 mine) and quartz lode and shear-hosted hydrothermally emplaced
bodies proximal to fault conduits. Smaller stockwork bodies within felsic intrusives are also
common. As is typical of the Archaean Shield, the deep weathering profile at Mt. Magnet has
resulted in supergene enrichment and hypogene dispersion of gold in the oxidizing environments.
These effects lend themselves well to the process of small scale open pit mining. Historically
underground mining of primary lodes was the largest contributor to Mt. Magnets gold production.
Mining Operations. The Mt. Magnet operations are engaged in underground, open pit and waste rock
mining. These operations are subject to the entire underground, open pit, and waste rock mining
risks detailed in the Risk Factors section.
Underground operations at Mt. Magnet consist of the Hill 50 and St. George mines, each of which
operates a decline. The Hill 50 mine, which is approaching 1,525 meters in depth, is currently one
of Australias deepest underground mines. The St. George Mine is approximately 300 meters in depth.
Underground mining is conducted by decline tunnel access. The principal challenges facing the Hill
50 underground mine is its continuing depth and the geotechnical, ventilation and cost impediments
that increased depth imposes, including increased ground stress and potential increased seismic
activity. A decision was taken in May 2007 to put the Hill 50 mines decline development on hold
due to significant seismic activity, effectively putting it in harvest mode.
With the closure of Star, the development of the new underground mine at the St. George open pit
provided additional underground tonnage for the Mt. Magnet operations. Underground development at
St. George started in December 2005. The first stope was mined in the second quarter of fiscal
2006. Underground mining continued at this mine during fiscal 2007. This mine reached its economic
depth limit during fiscal 2007, and was put in harvest mode, with mining operations ceasing in
October 2007. Open pit production was hindered by the delay in the start up of the Cue open pits
until the last quarter of fiscal 2005 as a result of delayed mining approvals and extended
contractor negotiations, although these were subsequently resolved and mining commenced in fiscal
2006. Open pit mining mainly took place around Mt. Magnet during fiscal 2007.
Surface operations at Mt. Magnet exploit several medium-sized open pits, as well as numerous
smaller open pits. Surface materials from areas previously involved in production, including waste
rock dumps and tailings dams, are also processed at Mt. Magnet. The principal challenge facing the
Mt. Magnet operations is that the open pits are situated on small orebodies, which results in short
mine lives. As a result, we must continuously locate, evaluate, plan, develop and bring into
production a succession of open pits to access additional reserves. Maintaining grade and managing
the increased geotechnical complexities of the Hill 50 and St. George underground mines also
remains critical. See Risk Factors Risks Relating to Our Business and Our Industry To maintain
gold production beyond the expected lives of Harmonys existing mines or to increase production
materially above projected levels, Harmony will need to access additional reserves through
exploration or discovery.
The table details the operating and production results from our operations at Mt. Magnet for the
fiscal years 2007, 2006 and 2005.

Recovered grade was 0.078 ounces per ton in fiscal 2006 compared to 0.066 ounces per ton in fiscal
2005. This was due to improving grade both from the underground and open pit during the year. Tons
milled were 1,918,000 in fiscal 2006 compared to 2,743,000 in fiscal 2005. Ounces sold decreased to
148,822 in fiscal 2006, compared to 181,233 in fiscal 2005. This decrease was primarily attributed
to lower production from open pit and underground operations during the period.
Cash costs per ounce were $399 for fiscal 2006, compared to $336 for fiscal 2005. This increase was
due to higher underground and open pit contracting cost due to the underlying mining cost increases
in the Western Australian market environment.
Tons milled in fiscal 2007 were 1,875,000 compared with 1,918,000 in fiscal 2006, and ounces sold
in fiscal 2007 were 136,428, compared with 148,822 in fiscal 2006, mainly as a result of
significantly less production from open pits during the year and a seismic event at Hill 50 during
May 2007, which also resulted in the reduction in the recovery grade from 0.078 ounces per ton to
0.073 ounces per ton.
Cash costs per ounce were $518 in fiscal 2007, compared to $399 for fiscal, 2006. A large portion
of this increase was due to the underlying mining cost increases in Western Australia.
The current mine plan for Mt Magnet sees production halt in January 2008. The majority of the
declared ore reserves will be mined by this date. The mines will be closed and the processing plant
will be placed on care and maintenance. As mentioned previously the company has signed a Letter of
Intent with Monarch Gold to purchase the site.
Plant. The Mt. Magnet operations include one metallurgical plant which was built in 1989 as a CIL
plant and upgraded in 1999 to a CIP plant. Actual throughputs of the Mt. Magnet plant varies based
upon the blend of oxide and sulphide ores in their feed. Processing capacity is an estimate of
nominal throughput based on a 70% hard (sulphide) and 30% oxide (soft) blend. The following table
sets forth processing capacity and average tons milled during fiscal 2007 for the Mt. Magnet plant:

Throughput rates at Mt. Magnet decreased in fiscal 2007 due to delays in approvals to commence
several small open pits and also due to a substantial part of the feed material being hard in
nature.
In fiscal 2007, the Mt. Magnet plant recovered approximately 91.8% of the gold contained in the ore
delivered for processing. A decision was taken in March 2005 to reduce throughput of the plant by
taking one circuit offline, as is reflected in milling rates for fiscal 2006. This was done to
process higher grade ore and to extend the mine life.
Capital Expenditure. Harmony spent $20.2 million in capital expenditure at the Mt. Magnet
operations in fiscal 2007, primarily for underground development and plant components. We have
budgeted approximately $14.2 million for capital expenditure at the Mt. Magnet operations during
fiscal 2008, which largely consist of open pit development at the Western Queen South open pit and
plant maintenance. However, this amount will be reduced to critical maintenance only, once open
pit development has stopped in anticipation of the buyer taking over.
90
Exploration. Activities at Mt. Magnet, Western Australia, were hampered in fiscal 2007 by slow
approval of work programmes and introduction of new legislative requirements regarding flora
surveys over certain areas of banded iron formation (BIF) outcrop. Target generation activities
were undertaken in the Cavangahs, Mirabaloo and broader Mt Magnet areas with drilling activities
concentrated on final resource definition of the open pits mined
during the year. A$5.5 million (US$4.3 million) was
spent on exploration during the year.
South Kalgoorlie Operations
Introduction. The South Kalgoorlie Operations are made up of New Hamptons Jubilee Operations and
Hill 50s New Celebration operations. Since the commencement of operations to June 30, 2007, total
gold production from the mines in the South Kalgoorlie area has exceeded 2.2 million ounces. In
fiscal 2007, South Kalgoorlie operations accounted for 4% of Harmonys total gold sales, and
accounted for 3% of Harmonys total gold sales in 2006 and 4% in fiscal 2005.
In July 2007 Harmony announced the sale of the South Kalgoorlie Mine to Dioro Exploration NL. The
transaction is expected to be concluded during the December 2007 quarter.
History. The South Kalgoorlie operations included several open pits at Jubilee and New
Celebration, as well at the Mt. Marion underground mine. The Jubilee operations were originally
comprised of the large Jubilee open pit and a number of smaller open pits. The New Celebration
operations were initially developed in 1987 by Newmont exploiting the same ore body that hosted the
Jubilee Pit. Hill 50 acquired these operations from Newcrest Mining Ltd. in June 2001. The Mt.
Marion decline was established in 1998. Open pit mining ceased at the South Kal Operations at the
end of fiscal 2005, with only low grade stockpiles treated during fiscal 2006 together with Mt.
Marion ore. During fiscal 2007 open pit mining recommenced at South Kalgoorlie Mines, with a
cutback on the Hampton Boulder Jubilee (HBJ) pit, as well as the Shirl open pit.
Geology. The South Kal mines are located approximately 30 kilometres south of Kalgoorlie in the
Eastern Goldfields region of Western Australia. The South Kal orebodies are located in a number of
geological domains including the Kalgoorlie-Kambalda belt, the Boulder-Lefroy Structure, the
Zuleika Shear, the Coolgardie Belt and Yilgarn-Roe Structures. At South Kal, the mining tenure and
geology straddles the three major fault systems or crystal sutures considered to be the main ore
body plumbing systems of the Kalgoorlie goldfield. The geology consists of Archaean greenstone
stratigraphy of basalts and komatiites with intercalated sediments, tuffs, volcaniclastics and
later felsic intrusives. Late stage and large scale granitic (Proterozoic) intrusion has stoped out
large sections of the greenstone. Quartz filled lode and shear-hosted bodies are the most dominant
among many mineralization styles. Large scale stockwork bodies hosted in felsic volcanics are an
important contributor to bulk tonnage of relatively low grade deposits.
Mining Operations. The South Kal operations are engaged in open pit, underground and waste rock
mining. These operations are subject to all of the underground, often pit and waste rock mining
risks detailed in the Risk Factors section.
At the South Kal operations, during fiscal 2007 open cast mining took place at Shirl open pit,
together with a cutback project on the HBJ open pit. The HBJ open pit will have a mine life of
three years and consist of 3.3 million tons of 0.048 ounces per ton. The Shirl open pit feedstock
as well as low grade stockpiles were processed during the year together with ore from the Mt.
Marion underground, while exploration continued to identify new and additional open pit sources.
The discovery of the Shirl prospect during fiscal 2006, which resulted in an open pit reserve of
50,000 ounces and a 15 month mine life, together with an improved gold price environment, lead to
the recommencement of open pit mining at South Kalgoorlie mines during fiscal 2007. The primary
challenge facing the South Kalgoorlie operations is identifying adequate sources of new open pit
and underground reserves and managing the geotechnical risk on the HBJ pit cutback. See Risk
Factors Risks Relating to Our Business and Our Industry To maintain gold production beyond the
expected lives of Harmonys existing mines or to increase production materially above projected
levels, Harmony will need to access additional reserves through development or discovery.
The Mt. Marion underground mine, which ceased operations in June 2007, faced challenges similar to
those faced by the Mt. Magnet underground operations; however, depths at Mt. Marion are much
shallower (740 meter vertical depth versus 1,300 meter vertical depth at Mt. Magnet). The Mt.
Marion mine was also exposed to risks typical of mechanized mines, including geotechnical issues,
mine dilution and unpredictable remedial ground support after mine blasting. During fiscal 2006
development of the Mt. Marion decline ceased, as the mine reached its economic depth limit, which
led to the closure of the mine in June 2007.
Detailed below are the operating and production results from the South Kalgoorlie operations for
the fiscal years 2007, 2006 and 2005:

Tons milled in fiscal 2006 were 1,480,000 compared with 1,405,000 in fiscal 2005, and ounces sold
in fiscal 2006 were 82,639 compared with 115,615 in fiscal 2005. This decrease in ounces, and
increase in tons, was primarily attributable to open pit throughout for the year being replaced by
low grade stockpiles, which also caused the reduction in grade.
Cash costs per ounce were $454 for fiscal 2006, compared to $340 for fiscal 2005. This increase was
due to higher underground and open pit contracting cost due to the underlying market increases in
the Western Australian mining environment and lower gold production levels. Recovered grade was
0.056 ounces per ton in fiscal 2006 compared to 0.082 ounces per ton in fiscal 2005. This decrease
in ounces, and increase in tons, was primarily attributable to open pit throughout for the year
being replaced by low grade stockpiles, which also caused the reduction in grade.
Tons milled in fiscal 2007 were 1,391,000 compared with 1,480,000 in fiscal 2006, and ounces
recovered in fiscal 2007 of 88,371 compared with 82,639 in fiscal 2006. This increase in ounces
compared with the decrease in milled tons, were primarily attributable to the increase in the
recovery grade from 0.056 ounces per ton from fiscal 2006 to 0.064 ounces per ton in fiscal 2007.
The increase in the recovery grade is as a result of the mining of mostly higher grade underground
ore. The decrease in throughput is primarily the result of tank refurbishments at the Jubilee
plant.
Cash costs per ounce were $504 for fiscal 2007, compared to $454 for fiscal 2006. This increase was
due to higher underground and open pit contracting cost due to the continuing increase in the
underlying Western Australian mining environment and higher gold production levels.
Plants. The South Kal operation has a metallurgical plant located at Jubilee. This CIL treatment
plant is capable of treating the planned production from the mining operations. Ore is hauled from
the open pits and from low grade stockpiles, as well as from the Mt. Marion underground mine to the
treatment plant by conventional road trains. Actual throughputs of the Jubilee plant vary based
upon the blend of oxide and sulphide ores in their feed. Processing capacity is an estimate of
nominal throughput based on a 70% hard (sulphide) and 30% soft (oxide) blend.
The New Celebration plant was sold during fiscal 2006 for A$3.0 million. This plant was originally
commissioned in 1986 as a CIP plant and later upgraded in 1988 by the addition of a larger parallel
circuit.

Throughput rates in fiscal 2007 were lower than capacity due to tank refurbishments at the Jubilee
plant.
In fiscal 2007, the Jubilee plant recovered approximately 89.3% of the gold contained in the ore
delivered for processing compared to 90% in 2006. Processing volumes exceeded normal capacity at
the Jubilee plant during fiscal 2006 as a result of the large quantity of low grade stockpiles
treated during the year compared to the normal blend of open pit and underground ore in previous
years.
92
Capital Expenditure. Harmony spent $6.7 million in capital expenditures at South Kalgoorlie,
primarily for the HBJ open pit cutback and to a lesser extent pre-production mining at Shirl open
pit and plant refurbishments. Due to the sale of the South Kal operations, we have not budgeted for
capital expenditures for 2008.
Exploration. On-mine exploration success was achieved during fiscal 2007 at South Kalgoorlie with
definition of underground mineralization at the Shirl open pit, bringing the total Shirl
mineralization to 221,000 ounces of gold. The Shirl deposit is a sub-vertical gabbro-hosted lode
bounded by ultramafics, combined with mineralised cross-cutting shears and intersected by late
porphyry intrusions. Exploration activities focused on larger base load targets along the main
Boulder Lefroy Fault and within Location 59 during fiscal 2007. Boulder Lefroy Fault exploration
targets have, in part, been generated by the AMIRA Stress Transfer Modeling project undertaken in
fiscal year 2006. The project involves the application of stress transfer modelling techniques
developed for modern seismogenic earthquake prediction to certain types of ore deposits associated
with major fault systems with the aim of predicting ore location. Location 59 exploration targets
have been developed through interpretation of detailed magnetics and the relationship to known
mineralisation styles.
Exploration activities were scaled back in the second half fiscal 2007 in anticipation of the sale
of the operation with $2.9 million spent.
Papua New Guinea Operations
Overview
Introduction. Harmonys lease holding in PNG is located southwest of Lae in the Morobe Province
and encompasses over 3,480 square kilometers of tenure. The tenements are outlined in the figure
below and fall into three main blocks centered in the Morobe province. These include the Wafi
leases (440 square kilometers), the Morobe Hidden Valley leases (971 square kilometers) and the
Morobe Coast EL (2,069 square kilometers).
93
Harmony PNG tenement locations. In terms of regional geological setting, the tenements cover a
portion of the PNG mobile belt. The mobile belt comprises tract of metamorphosed Lower Jurassic and
Cretaceous sediments and oceanic crust. These rocks have undergone deformation in the collision
zone between the Australian and Pacific Plates and multiple intrusive events including Tertiary
granodiorite and younger mineralized porphyries. The PNG mobile belt hosts a number of major gold
and copper-gold deposits including the Wafi-Golpu and Hidden Valley Projects which are 100% owned
by Harmony.
Exploration expenditure outlook for fiscal 2008 is currently estimated at $19.49 million (A$22.97
million). Results from this work have been highly encouraging, as a number of targets with the
potential for major stand-alone gold and copper/gold deposits have been identified and advanced to
the drill testing phase.
Harmony currently has offices in Lae and Wau, to facilitate the development of the Hidden Valley
project and support the pre-feasibility work on the Wafi Golpu copper gold project. In 2006 a
technical support office was opened in Brisbane to support the construction phase of the Hidden
Valley project as well as the evaluation of the Wafi and Golpu prospects.
Harmony has completed its Golpu copper stand alone pre-feasibility study (PFS) during the June
2007 quarter, on time and within budget. The study has identified a technically and economically
viable project plan, with the highlight being the definition of a probable ore reserve.
Importantly, the mining plan has restricted the overall average arsenic grade to 136ppm, with the
highest grade in any single year restricted below 300ppm, to ensure that a saleable concentrate is
maintained throughout the project life. The Wafi gold component of the pre-feasibility study was
completed during October 2007, which will be technically reviewed during the December 2007 quarter.
94
Hidden Valley Project
Introduction. The Hidden Valley project entails the construction of a significant gold and
silver mine. This mine will process 4.6Mt of ore a year from the two open pits. The Hamata orebody
is one small pit and the Hidden Valley and Kaveroi orebodies are in a much larger open pit. The
mine is located in a highly prospective exploration lease area and it is envisaged that, as active
exploration continues, the life of the process facility may be extended as it is fed from a number
of sources. The Hidden Valley Project is owned by Harmony through our wholly owned PNG subsidiary,
Morobe Consolidated Goldfields Ltd. This project comprises four exploration licenses of 966 square
kilometers in the Wau District of Morobe Province, PNG and is located 210 kilometers
north-northwest of Port Moresby and 90 kilometers south-southwest of Lae, the two largest cities in
PNG. Access to the project is presently by sealed road from the deepwater port of Lae to Bulolo. An
all weather gravel road from Bulolo to the Hidden Valley mine site has been constructed by Harmony
to access the site.
History. Alluvial gold was first discovered at Hidden Valley in 1928 but it was not until the
early 1980s that the area was investigated by CRA Exploration using modern exploration techniques
that resulted in the discovery of the Hidden Valley and Kaveroi gold deposits on EL 677. A number
of feasibility studies have been prepared for the Hidden Valley Project by the various owners,
including one by Abelle in 2003. During fiscal 2006 the Abelle feasibility study was extensively
reviewed and updated by Harmony to: (a) reflect changes in the projects ore body interpretation;
(b) incorporate increases in capital and operating costs as a result of energy prices and scarce
resources in the mining industry as well; and (c) resolve technical aspects that were outstanding
from the previous study. The updated feasibility study was presented to the Harmony board during
June 2006 and they approved construction of the project.
Site Access. The Hidden Valley site is located approximately 90 kilometers south-southwest of
Lae, which is the nearest deepwater port for the project, and the Capital of Morobe Province.
Access to the site from Lae uses an existing 110 kilometers sealed two-lane main road to the town
of Bulolo, continuing to Hidden Valley via an all-weather two-lane access road constructed by
Harmony. Work commenced on the construction of the Hidden Valley access road to the site from
Bulolo town in October 2005. The road reached the mining lease boundary in May 2006 and the
in-filled road network has been extended to the Hidden Valley deposit, Pihema Creek and the Hamata
plant site. Pihema Creek has been diverted and platforms have been established for most of the
project infrastructure, such as the permanent camp and the administration building. Work has
commenced on the Tailings Storage Facility and the Hamata plant site. Harmony contracted a road
construction manager and a core of operators with extensive PNG road-building experience to
undertake this part of the project, utilising equipment bought by Harmony for construction
purposes.
Engineering Procurement and Construction Management Contract. Following board approval, a
small owners team of experienced construction professionals was recruited, including several key
individuals with extensive PNG experience, to ensure that project objectives, scope of work and all
other project requirements are met. In July 2006 an agreement was reached with the engineering
group Ausenco Limited to provide engineering procurement and construction management services for
the project. Ausenco started immediately with the preparation of a project execution plan as well
as the detailed design stage of the project which is set for completion at the end of December
2007. By the end of fiscal 2007 the detailed design was approximately 45% complete and 82 of a
planned 102 procurement/contract packages have been put out to enquiry. To date, 52 packages have
been awarded.
Power supply. The ability to obtain an alternate power supply from PNG Power Limited (PPL
PNGs national power supplier), is of critical importance to the economics of the project. On
May 14, 2007, Harmony announced that it had signed an agreement with PPL to supply the Hidden
Valley mine with electricity. PPL has committed to construct new transmission lines and
infrastructure in order to supply hydro-electricity from the Yonki Dam. Supply is expected to
commence on January 1, 2010.
In addition Harmony acquired diesel generators and will install them for the purpose of
providing 100% backup power supply to the project, if required.
Customs and Excise. In November 2006 the PNG National Executive Committee approved exemptions
to customs and excise on a range of commodities that will be required for the construction of the
project. This still has to be gazetted, however, customs officials at Lae port are already applying
the exemptions, based on the draft gazettal notice.
Mining Fleet. The mining equipment required for the project consists of: four 180t
excavators, a fleet of nine 175t haul trucks and a range of ancillary equipment. Supply and
maintenance agreements for this fleet were signed in September 2006. The delivery of the first
batch of mining equipment for pre-stripping took place in the second quarter of fiscal 2007 and the
delivery of the second batch is expected in the December 2007 quarter.

are 2.868 million ounces at 0.0586 ounces per ton. Silver proven and probable reserves at Hidden
Valley/Kaveroi and Hamata amount to 41.99 million ounces at 0.9928 ounces per ton. Extensive
drilling is currently being undertaken at the Kaveroi prospect adjacent to the Hidden Valley ore
body, with the intention to add additional reserves to the project.
Environment. The Environment Management Plan, which is a requirement of the mining lease, has
been approved by the PNG Department of Environment. The key environmental issue for the project is
the effective management of water quality in the Bulolo and Watut rivers. A range of control
measures will be implemented for acid rock drainage, sediment runoff and tailings facility
discharge water quality. Work continues on baseline studies and monitoring programs required for
both the construction and operational phases of the project. Re-engineered surface designs have led
to the tailings storage facility capacity being increased to 46.3 million tons and the waste dumps
design now complying with acid rock drainage and other environmental commitments.
Community affairs/landowner discussions. Community support and development of the mine in
compliance with the memorandum of agreement with landowner groups is critical to the success of the
project. Meetings are held regularly with these groups and officials from the provincial and
national government to monitor progress and ensure these objectives are met. A range of
opportunities for the commercial participation of landowner groups in the development of the
project are being considered as a priority, and community relations initiatives focused on positive
outcomes for health, education and infrastructure are ongoing.
Project Overview. Once fully developed, the Hidden Valley Mine is expected to process
4.6 million tons of ore per annum from ore mined at two open pits, the Hamata ore body in one small
pit and the Hidden Valley and Kaveroi orebodies in a much larger pit. Expected annual production
will be 285,000 ounces of gold per annum, with a peak production of 317,000 ounces, and
4.05 million ounces of silver. Expected mine life is 9.7 years, with 44.6 million tons treated at
an average grade of 0.057 ounces per ton. The construction period is estimated to be 30 months,
with the mine expected to be commissioned by March 2009.
The resources will be mined in a sequence that sees the low silver, high gold Hamata ore mined
first, with plant and infrastructure development for the project developed in close proximity to
the Hamata deposit. The next ore mined will be the Hidden Valley/Kaveroi oxide/transition ores
(high silver) followed by the Hidden Valley/Kaveroi primary ores.
Plant. As part of the project a treatment plant was brought from Misima Mines Limited and
transported to Lae in April 2005. Parts of the plant that will be utilized in the project have been
identified and refurbished in fiscal 2007 with the remainder to be disposed of. The plant is stored
in Lae and its components will be transported to Hidden Valley for installation as the project
proceeds.
Once completed, the processing plant is expected to process ore at a rate of approximately
4.6 million tons per annum and has been designed with three distinct process routes that complement
the metallurgical characteristics of the three ore types to be mined. The processing plant will
commence as a primary crushing, grinding (with the incorporation of a gravity gold recovery
circuit), CIL, Merrill-Crowe zinc precipitation, goldroom and tailings detox plant for the low
silver Hamata ores, revert to a primary and secondary crushing, grinding, flotation, concentrate
regrind, counter-current decantation circuit with Merrill-Crowe zinc precipitation, flotation
concentrate and tailing CIL, goldroom and tailings detox for the high silver oxide/transition ores
and then a similar circuit without flotation tail CIL for high silver sulphide ores from Hidden
valley/Kaveroi ores. The gravity gold recovered will be processed through an intensive cyanide
leach followed by electrowinning circuit to produce a high quality ore product.
Ore will be delivered by truck to the Hamata and Hidden Valley crusher stations. Crushed
Hamata ore will be delivered by conventional conveyor to the primary stockpile and Hidden Valley
ore will be delivered via an overland pipe conveyor to the same stockpile.
All tailings will be stored in a tailings storage facility, and all water recovered will be
subject to detoxification prior to being re-cycled or released to the environment. The processing
plant and tailings storage facility will be built to meet or exceed the requirement of the
International Cyanide Management Code. Construction completion is planned for the first quarter of
2009 with the first gold expected to be produced in March 2009.
Government royalty and other rights. The gold and silver production from the Hidden Valley
Project will be subject to a 2% royalty, payable on the net return from refined production if
refined in PNG or 2% royalty on the realized price if refined out of PNG.
The government of PNG also has a statutory right to acquire up to a 30% participatory interest
in mining development projects, at sunk cost. However the memorandum of agreement signed between
Harmony and the government reduced the participation right to
96
5%, should the government wish to exercise it. Once an interest is acquired by the government
of PNG, it contributes to the further exploration and development costs on a pro rata basis.
Third Party Royalties. On March 28, 2007 Harmony announced that it had concluded negotiations
with Rio Tinto under which the parties agreed Harmony would purchase the Rio Tinto rights under a
royalty agreement relating to Hidden Valley, which was entered into prior to the acquisition by
Harmony of the Hidden Valley and Kerimenge deposits in Papua New Guinea. Under the royalty
agreement, Rio Tinto has the right to receive a portion of between 2% and 3.5% of future ounces
produced by the Hidden Valley mine in PNG. The consideration to be paid by Harmony to Rio Tinto
will be $22.5 million to be settled with new Harmony ordinary shares to the value of $20 million
and the balance of $2.5 million paid in cash when the closing of the transaction occurs.
The transaction should reduce cash costs per ounce of gold produced at Hidden Valley, and all
further extensions to the project, mine life and reserves will be free of this royalty. The PNG
Mining Advisory Council (MAC) has to approve the transfer of the royalties between the parties
before the transaction becomes effective which is anticipated to be given in the second quarter of
fiscal 2008.
Capital Expenditure. Capital expenditure on the project for fiscal 2007 was $72 million
compared to $16 million spent in fiscal 2006. Capital was mainly spent on completing the access
road to the Hidden Valley and Hamata mine sites, site earthworks and acquisition of construction
fleet and a portion of the mining fleet. Other areas of significant expenditure were for process
equipment and management related costs.
The total project capital cost is estimated to be $364 million (A$455 million), which
represents a 23% increase on the last reported budget. Increases in costs were primarily caused by
market forces resulting from the high demand created by resource development projects in the
region. The only significant change in the scope of work was the move of the Hidden Valley ROM pad
from the west to the eastern side of the pit. This was necessary because geotechnical drilling and
advice received identified an unacceptable level of risk regarding potential slope stability. This
value excludes $37 million for mine fleet repayments post the construction phase as well as
$22.5 million for the Rio Tinto royalty buy-out which is not considered part of the construction
capital.
Morobe Consolidated Goldfields Limited (MCG) Tenements
The MCG tenements encompass the Hidden Valley Project and include all tenements south of the
Bulolo township. The tenements host the Hidden Valley and Hamata mine developments and the
historical Kerimenge deposit. They remain highly prospective for similar deposits and for smaller
high-grade satellite resources.
The aim of the exploration program on the Morobe Consolidated tenements is three-fold:
|
|
|
Major new stand alone discoveries; |
|
|
|
|
High-grade drivers to improve cash flows of the Hidden Valley Project; and |
|
|
|
|
Additional reserves to substantially increase mine life of the Hidden Valley Project. |
Fiscal 2007 programs have focused on the Kerimenge Prospect, and on regional exploration on
the Morobe Coast EL1403. In addition to the existing prospects, project generation such as capture
of historical data and grassroots exploration activities, which include mapping, stream sediment
sampling and integration of results with regional magnetic data, will continue.
On the Hidden Valley Mining Lease ridge and spur and grid based soil sampling is planned for
the first half of fiscal 2008. Furthermore, with mine construction underway new road cuttings and
site preparation for infrastructure has unearthed a number of alteration zones which have never
been sampled or mapped. Mapping of these new zones and integration with geochemical data and
detailed Helimagnetics will provide a powerful tool for identifying new targets on the Hidden
Valley Mining Lease.
Kerimenge and the broader prospect potential
Introduction. The main focus of exploration activities during the year has been on the Kerimenge
deposit which lies approximately seven kilometers east of the proposed Hamata Processing Plant
site. Drilling has targeted gold mineralization on the Kerimenge fault, and its southern strike
extension. A total of 11 holes for 1671m have been completed during fiscal 2007 by Harmony. Results
have been encouraging.
97
Geology. Gold mineralization occurs as disseminated pyrite and arsenopyrite in hydrothermal
breccia, and with quartz veined stockwork in Andesite porphyry. Drilling remains ongoing. Of
particular importance is the drill intercept obtained in QD136. The mineralization occurs in
brecciated metasediments in the footwall of the Kerimenge fault and represents a new style of
high-grade mineralization that was previously unknown at the prospect.
Project Status. Compilation of historical exploration data around the broader Kerimenge
prospect area has shown a number of high grade trench results that have not seen follow-up
drilling. These trench results are broadly coincident with limestone contacts and mapping, and
drill testing is planned for fiscal 2008.
Morobe Coast Exploration License
Introduction. The Morobe Coast exploration license was granted in April 2006 and encompasses
some 2,068 square kilometers. The area lies to the southeast of the Morobe goldfield and Harmony
believes it presents grassroots exploration potential. Historical exploration work has been
limited, but returned anomalous gold assays in rock chip and stream sediment samples from the
Lokaniu volcanics. There has been little follow-up to determine the hardrock source, and no drill
testing has ever been undertaken on the tenement.
Project status. Following access and community liaison, a camp was established in November
2006. Field mapping and surface sampling programs commenced. Recent results from the Giu prospect
are highly encouraging.
Giu Prospect
The Giu prospect falls approximately ten kilometers southwest of the Morobe township on the
east coast of PNG. The prospect represents a district scale anomaly, twenty kilometers in diameter
with elevated gold rock chip and stream sediment geochemistry. The aim of the work programs is to
identify and develop prospect areas with the potential for stand-alone-gold (+/- related metal)
orebodies.
Mapping to date has outlined several areas of structurally controlled epithermal vein
mineralization, hosted in vesicular basalts. Rock chip results have been encouraging with anomalous
values of copper, gold, molybdenum and zinc returned.
Project Status. Field work continues including stream sediment sampling and excavation of
trenches over outcropping mineralized zones. Systematic stream sediment geochemical coverage is
currently scheduled for completion by the second quarter of fiscal 2008. Recommendations for
follow-up will be based on these results.
Wafi Golpu Project Area
Introduction. The Wafi prospect is owned through a wholly owned Harmony subsidiary, Wafi
Mining Limited. The first exploration at Wafi dates back to the nationwide porphyry copper search
by CRA Exploration Ltd in the late 1960s. Elders Resources farmed-in to the project from 1989-1991
and AGF farmed-in to the project for a short period in 1997 prior to going into administration in
1998. Aurora subsequently acquired the project from Rio Tinto (CRA) in 1999, with ownership passing
to Abelle when they merged with Aurora in 2002. Harmony assumed control of the Wafi project as a
result of its acquisition of Abelle in 2003. The project is held under four contiguous exploration
licenses totalling 996 square kilometers, and comprises two separate ore systems located within
close proximity of each other known as the Wafi Gold Project and the Golpu Copper/Gold Project
respectively. The Wafi gold mineralization is hosted by sedimentary/volcanoclastic rocks of the
Owen Stanley Formation which surrounds the intrusive Wafi Diatreme. Gold mineralization occurs as
extensive high-sulphidation epithermal alteration overprinting porphyry mineralization and
epithermal style vein-hosted and replacement gold mineralization with associated wall-rock
alteration. We spent a total of $15.54 million (A$18.31 million) to conduct pre-feasibility
studies for the Wafi Gold and Golpu Copper/Gold Projects during fiscal years 2006 and 2007.
Geography. The Wafi prospect is located near Mt. Watut in the Morobe Province of PNG, 60
kilometers southwest of Lae and 60 kilometers northwest of Wau. The site is accessed by sealed road
(Lae to Bulolo) which comes within 5 kilometers of the eastern edge of the tenements and 10
kilometers from the Wafi camp. The Wafi camp is located at an elevation of approximately 400 meters
above sea level. The terrain is mountainous and forested in most areas. The Wafi Gold and Golpu
Copper/Gold prospects are serviced by the sealed Lae-Bulolo road to Timini and then by a dirt base
access track to the prospect which is now accessible during most weather conditions. The access
track is approximately 38 kilometers in length. The site is serviced by helicopter when the road
access is cut
98
due to poor weather or minor landslides. Immediately west of the project area, the Watut
Valley has a large area of flat land. The foothills of the Valley are planned to be utilized for
placement of ore processing and accommodation infrastructure.
Mining Reserves. Following completion of the Golpu Copper/Gold pre-feasibility study, a
probable ore reserve has been declared. The ore reserve is summarized in the table below:

The reserve is subject to a number of clarifications which are included in the ore reserve
statement. Major clarifications to be considered are:
The Golpu Ore Reserve is derived from the Golpu Stand Alone Project Pre Feasibility Study.
This study assumes a block cave underground mine with ore processed on site to produced a copper
and gold concentrate for shipping to smelter. Metallurgical Studies indicate that recoveries of 88%
for copper, 54% for gold and 36% for molybdenum can be expected. Metal prices are assumed at
US$2.30/lb for copper, US$520/oz gold and US$20/lb for molybdenum.
In declaring the probable reserve, the following considerations are required:
1. The PFS is completed to industry accepted standards for a PFS (±20-25% accuracy). The
outcome of further more detailed studies may affect the reserve.
2. The location for the tailings storage facility has not been finalised, however two
potential sites proximal to the project have been defined.
3. There are outstanding issues associated with traditional land owners required to be
resolved before the project is able to be constructed.
4. The Harmony Board has not yet committed to completing subsequent phases of study, or to
project construction.
It is not intended to declare a reserve for the Wafi gold ore bodies upon completion of the
respective PFS studies. It is considered that a number of unknowns will exist upon completion of
the current phase of study, and such unknowns will be required to be quantified prior to
declaration of a reserve.
Government Royalty and Other Rights. The metal production from the Wafi Project is subject to
a 2% royalty payable on the net return from refined production if refined in PNG or a 2% royalty
payable on the realized price if refined outside of PNG. The government royalty has been accounted
for in project financial models. PNG also has a statutory right to acquire up to a 30%
participatory interest in mining development projects at sunk cost. Once an interest is acquired by
the government of PNG, it contributes to the further exploration and development costs on a pro
rata basis.
Third Party Royalties. Pursuant to the sale agreement of Wafi Mining Ltd to Abelle (via
wholly owned subsidiary companies) from Rio Tinto, a royalty of 2% on gold production or a 2% NSR
(net smelter return) from copper-gold concentrates is payable to Rio Tinto as a deferred
acquisition cost. The royalty has been accounted for in project financial models.
Additional Prospects and Exploration Potential. The Wafi pre-feasibility study concentrates
on developing the Golpu copper-gold, the high-grade link zone mineralization, and the
non-refractory (oxide) portion of the A and B zone gold mineralization. However, excellent
prospects remain in the immediate vicinity of the existing resource areas on the northern and
western margin of the diatreme. Recent drill intercepts at Western Zone highlight the potential for
deep high grade Link Zone style mineralization off the diatreme margin. With the exception of
some discrete areas of drilling, the bulk of the area off the western and northern quarters of the
diatreme margin remains untested. Other prospect areas peripheral to the Wafi core complex that
require additional exploration include the Nambonga and Malaria zones. There are several
exploration targets within a ten kilometers radius of the Wafi site, including Biamena,
99
Bawaga and Kasiago, which have historical aeromagnetic signatures and anomalous stream
sediment data. The Biamena and Nambonga deposits are the subject of current drilling programs.
Capital Expenditure. No capital expenditure was incurred during fiscal 2007 or 2006 as the
pre-feasibility study was still underway and costs were expensed as a result. The pre-feasibility
study is due for completion in two phases. The Golpu study was completed in the last quarter of
fiscal 2007, and the Wafi study is due for completion in the second quarter of fiscal 2008.
It is expected that review of pre-feasibility studies will be conducted during the Quarters
two and three of fiscal 2008. Depending on the assessment of review teams, it is expected that
Definitive Feasibility studies will commence during Quarter 4 of fiscal 2008.
Wafi Gold Projects
Introduction. The Wafi Gold resource is comprised of three main zones: Zone A; Zone B; and
the Link Zone (high grade lenses within Zone B). Additional to the Wafi resource the Western Zone
is an advanced exploration project.
Geology. The pre-feasibility study undertaken by Harmony has focused on extraction of the
high grade Link Zone material, and on delineation of shallower oxidized mineralization, amenable to
high gold recovery under standard cyanide leach conditions (associated with Zones A and B).
Additional exploration activities have focused on the discovery of additional Link Zone style
mineralization (such as the Western Zone) which may have the potential to improve Wafi gold project
economics.
Pre-feasibility test work for the Link Zone has focused on whole ore pressure oxidation of the
Link Zone ore (which was shown to be technically viable during the AGF test work program detailed
above), and comminution test work. Test work completed during the study further demonstrated the
technical viability of the processing method, with gold recoveries of around 95% achieved. Only 45%
of sulphides present in the ore are required to be oxidized to achieve optimal gold recovery.
Previous studies assumed complete oxidation of sulphides. Work undertaken to complete the study in
Quarter 1 of fiscal 2008 will focus on determining the financial viability of the process, and the
overall project plan for the Link Zone.
Metallurgical test work for the Non-Refractory gold ore (NRG1") has focused on establishment
of cyanide recoveries in both the transitional and fully oxidized ores across the known
mineralization. Test work has shown that the 95% recovery of gold in completely oxidized ores is
consistently achieved, however recovery in the transitional material remains variable. Initial
indications have shown that recoveries averaging 84% to 86% are able to be achieved, however
further definition is still required. The PFS will be completed assuming 84% recovery in the zone.
Should the PFS identify the project to remain economic at that recovery, further work to define
recovery in each area of the ore body will be undertaken. Some planned drilling in the zone was not
completed due to time constraints and delays experienced during the program. Given the cost of
maintaining the site it was decided to complete the PFS based on information at hand, to ensure
that excessive expenditure was not undertaken prior to confirmation that the ore body is economic.
Project Status. Geotechnical, mining, infrastructure, and environmental investigations have
been undertaken as part of the Link Zone and NRG1 study, in parallel with the Golpu studies.
Synergies between the Wafi Gold projects and the Golpu Copper project have been utilized during the
studies to minimize cost as far as possible. The synergies between projects will also be utilized
in the final mine development plan to produce the best economic results for the project. The
finalized economic model will be available during the second quarter of fiscal 2008.
The pre-feasibility study for the NRG1 and Link Zone deposits is due for completion in the
second quarter of fiscal 2008. Scoping studies completed for both projects during fiscal 2007
indicated that both projects may be viable, with the Link Zone appearing particularly positive.
Wafi Leases
Porphyry copper-gold and stand-alone gold targets represent the best potential to crystallize
value from the Wafi tenement group. Biamena, Bawaga, and Kesiago all have the potential to deliver
Wafi-Golpu style mineralization. Regional magnetics also show favorable structural environments
for major gold or copper-gold systems in areas where there has been little or no previous
exploration. First pass exploration by way of stream sediment sampling, mapping and reconnaissance
rock chip sampling is recommended for these areas to identify new prospect areas and maintain the
grassroots end of the project pipeline.
100
Exploration within a one kilometer radius of the existing deposits at Wafi and Golpu remains
focused on adding high-grade underground or surface oxide resources. These targets have the
potential to impact significantly on the economics of the Wafi pre-feasibility study. Most of the
regional exploration within 10km of the Wafi site is focused on delineating additional copper
porphyry resources, or high grade gold ore bodies.
Golpu Copper-Gold Project
Introduction. The Golpu Copper-Gold Project, or Golpu Project, is located approximately one
kilometer northeast of the Wafi gold orebodies.
Geology. The Golpu host lithology is a typical zoned porphyry copper alteration halo, grading
from potassic to phyllic to advanced argillic upwards in the core. Outwards from the core the
alteration grades from the above to argillic potassic to propylitic. The mineralized body is a
porphyry copper-gold pipe with approximately 200 meters by 200 meters plan dimensions, slightly
north plunging and still displaying strong mineralization at grades similar to those in the rest of
the potassic alteration zone at 1.2 kilometers depth, the maximum depth to which it has been
drilled. Recent drilling and reinterpretation have shown that copper and gold mineralization extend
some way into the metasediment host rock immediately adjacent to the porphyry body. The mineralized
metasediment has potential to add up to 75% to the volume of the porphyry stock if additional
exploration defines the mineralization as part of the resource.
The surface expression is oxidized and leached to about 150 meters vertical depth, resulting
in a residual gold only mineralization from which the copper has been leached. At the oxidation
interface a strong 20-30 meters thick zone of supergene copper enrichment is developed which
transitions at depth into a lower grade covellite-enargite ore. Beneath this is a zone of more
covellite rich mineralization that contains lesser enargite and consequently less arsenic. From
approximately 300 meters below surface the ore exists in a covellite-rich (arsenic-poor) form
grading into a chalcopyrite-bornite rich zone from approximately 500 meters to its current known
depth of approximately 1.2 kilometers. Harmony completed the pre-feasibility study for Golpu,
during the last quarter of fiscal 2007. The PFS identifies a reserve of 71Mt @ 1.1%Cu, 0.6g/t gold,
and 121 ppm Molybdenum. There is potential to significantly increase the mining inventory if
additional mineralized metasediment material is able to be included in the resource estimate
following further exploration activities.
The metasediment domain comprises mineralization peripheral to the porphyry stock that is
hosted in the metasediments. Mineralization in the metasediment is distributed irregularly around
the porphyry stock with the majority occurring on the western side of the porphyry. Mineralization
occurs in all three alteration types: advanced argillic, phyllic and potassic. Further work during
subsequent phases of study will be planned with a view to converting the mineralized metasediment
to an indicated resource, and subsequently a probable reserve.
Importantly, the current pre-feasibility study test work has established that a coarser grind
size of p80 106 µm can be used to achieve these recoveries. Test work by previous owners
contemplated grinding ore to as fine as p80 50 µm in order to achieve similar or lower recoveries.
This represents a potentially significant reduction in operating costs.
Production of copper metal on site has not been considered during the current phase of study.
The cost of power at the site is presently high, with on site heavy fuel oil generation. It is note
expected that on site metal production will be viable unless power cost can be substantially
reduced.
Project Status. The Golpu pre-feasibility study was undertaken in parallel with the Link Zone
and NRG1 pre-feasibility studies. The Golpu pre-feasibility drilling was completed in September
2006. A full team of mining, processing, and infrastructure personnel (both in-house and consultant
personnel) have completed study. The Golpu pre-feasibility study is planned to be completed in the
first quarter of fiscal 2008.
Findings of the pre-feasibility study indicate that an annual production rate of 9 million
tones is optimal and achievable, utilizing the block cave mining method. Ore is planned to be mined
from the block cave, and conveyed via an underground decline to a processing plant located in the
Eastern foothills of the Watut River Valley, some four kilometers west of the deposit. Concentrate
produced will be either pumped or truck-hauled to the port of Lae for dispatch to Asian smelting
markets, with the transport method to be finalized in the completed PFS report due in the second
quarter of fiscal 2008.

REGULATION
Mineral Rights
South Africa
South African law provides for the separate ownership of surface and mineral rights. Prior to
the promulgation of the MPRDA on May 1, 2004, it was therefore possible for one person to own the
surface of a property, another to own rights to precious metals, and yet another to own rights to
base minerals. In terms of the MPRDA, all mineral rights in South Africa are now vested in the
South African state. The principal objectives of the Act are:
|
|
|
to recognize the internationally accepted right of the state of South Africa to exercise
full and permanent sovereignty over all the mineral and petroleum resources within South
Africa; |
|
|
|
|
to give effect to the principle of South Africas custodianship of its mineral and
petroleum resources; |
|
|
|
|
to promote equitable access to South Africas mineral and petroleum resources to all the
people of South Africa; |
|
|
|
|
to substantially and meaningfully expand opportunities for historically disadvantaged
persons including women, to enter the mineral and petroleum industry and to benefit from the
exploitation of South Africas mineral and petroleum resources; |
|
|
|
|
to promote economic growth and mineral and petroleum resources development in South
Africa; |
|
|
|
|
to promote employment and advance the social and economic welfare of all South Africans; |
|
|
|
|
to provide security of tenure in respect of prospecting, exploration, mining and
production operations; |
|
|
|
|
to give effect to Section 24 of the South African Constitution by ensuring that South
Africas mineral and petroleum resources are developed in an orderly and ecologically
sustainable manner while promoting justifiable social and economic development; and |
|
|
|
|
to ensure that holders of mining and production rights contribute towards socio-economic
development of the areas in which they are operating. |
Under the MPRDA, tenure over established mining operations is secured for up to 30 years (and
renewable for periods not exceeding 30 years each thereafter), provided that mining companies apply
for new order mining rights over existing operations within five years of May 1, 2004, or before
the existing right expires, whichever is the earlier date and fulfill requirements specified in the
MPRDA and the Mining Charter.
The Mining Charter was signed by government and stakeholders in October 2002 and contains
principles relating to the transfer, over a ten-year period, of 26% of South Africas mining assets
(as equity or attributable units of production) to HDSAs, as defined in the Mining Charter. An
interim target of 15% HDSA participation over 5 years has also been set and to this end, the South
African mining industry has committed to securing financing to fund participation of HDSAs in an
amount of R100.0 billion within the first five years of the Mining Charters tenure. The Mining
Charter provides for the review of the participation process after five years to determine what
further steps, if any, are needed to achieve the 26% target participation. In order to measure
progress in meeting the requirements of the Mining Charter, companies are required to complete a
Scorecard, in which the levels of compliance with the Mining Charter can be ticked-off after five
and ten years respectively. The Mining Charter and Scorecard require programs for black economic
empowerment and the promotion of value-added production, such as jewelry-making and other gold
fabrication, in South Africa. In particular, targets are set out for broad-based black economic
empowerment in the areas of human resource and skills development; employment equity; procurement
beneficiation and direct ownership. In addition, the Mining Charter addresses socio-economic issues
such as migrant labor, mine community and rural development, and housing and living conditions.
Currently, the South African Government has given its assurance that the Mining Charter will
take precedence over the more recently promulgated Black Economic Empowerment Act 2003 and, in
particular, the Codes of Good Practice published thereunder, which are of general application to
the South African economy. It is therefore envisaged that the Mining Charter will remain relevant
to securing the conversion of mineral rights.
102
We actively carry out mining and exploration activities in all of our material mineral rights
areas. Accordingly, the MPRDA has not had a significant impact on these mining and exploration
activities because we are eligible to apply for new licenses over our existing operations (some of
which have already been granted), provided that we comply with the Mining Charter. There can be no
assurance, however, that any licenses would be received. However, we have had several discussions
with the National Department of Minerals and Energy and have no reason to believe that the licenses
will not be granted.
We have already complied with the requirements of the Mining Charter, with an equivalent of
34% of production ounces qualifying as empowerment credit ounces. We have been working on our
program of licensing since 2004, which involved the compilation of a mineral assets register and
the identification of all of our economic, mineral and mining rights. We have secured all old
mining rights and validated existing mining authorizations. Our strategy has been to secure all
strategic mining rights on a region-by-region basis. The first application for conversion from old
order to new order mining rights was for the Evander Operations and was lodged on May 21, 2004.
The Evander mining license was the first conversion application in the region and in October 2004
we became the first senior company to convert old order to new order mining rights for our
Evander and Randfontein operations. Although it is not possible to estimate how long it will take
for each application to be processed by the regional offices of the Department of Minerals and
Energy, we have worked closely with the department to help ensure, to the extent we are able, that
the licenses are granted as swiftly as possible. The conversion of licences for all our remaining
operations were granted during November 2007 and will be executed before the end of January 2008.
The MPRDA also makes reference to royalties being payable to the South African state in terms
of the envisaged Mining and Petroleum Royalty Act which has not yet been finalized. However, a
Bill, known as the Royalty Bill, was made available for public comment. It is anticipated that the
Mining and Petroleum Royalty Act will only come into force in 2009. The introduction of the Mining
and Petroleum Royalty Act as law may have an adverse impact on the profits generated by our
operations in South Africa. We are currently evaluating the impact that the proposed Mining and
Petroleum Royalty Act may have with regard to our operations and no assurance can be given as to
whether or when the proposed Mining and Petroleum Royalty Act will be enacted.
The MPRDA:
|
|
|
limits ministerial discretion insofar as applications relating to the conversion of old
order mining rights are concerned, |
|
|
|
|
introduces a first-come first-served principle with respect to the consideration of
applications for new order mining rights, |
|
|
|
|
introduces a mining advisory board to advise the Minister of Minerals and Energy on
matters relating to minerals and mining, consisting of representatives of, inter alia, the
South African state, organized labor, organized business and relevant community based
organizations, |
|
|
|
|
provides for compensation for currently held rights in certain circumstances, and |
|
|
|
|
provides that a party aggrieved by an administration decision made in terms of the MPRDA
has the right of appeal to either the Director General or the Minister and may only take
matters to the courts once that party has exhausted his or her remedies in terms of the
appeal procedures that are to be set forth. |
Australia
In Australia, all minerals are owned by the Australian government except where it has granted
freehold title to the land, in which case ownership of minerals other than gold, silver and other
precious metals vests in the freehold title holder. Mining companies must pay royalties to the
Australian government based on production.
Each Australian state has its own mining legislation and administers mineral exploitation
through the issuance of a variety of exploration and mining tenements.
Mt. Magnet, New Hampton and South Kal hold various mining tenements issued by Western
Australias Department of Industry and Resources in accordance with the provisions of the Mining
Act 1978 (WA). In the conduct of their operations, they must comply with a wide range of statutes,
including the Mining Act, the Mines Safety and Inspection Act 1994 (WA) and various environmental
statutes, as well as the provisions of the tenements themselves and various operating and
abstraction licenses issued by the States Department of Environmental Protection and the Water and
Rivers Commission.
103
All mining leases in Western Australia are secured by environmental performance bonds which
cannot be relinquished or cancelled without the approval of the Department of Industry and
Resources. The amounts of the bonds are assessed on an annual basis and are audited by a regional
inspector.
Hampton Gold Mining Areas is the freehold owner of the Hampton Lands, which are freehold
estates in Western Australia in respect of which the state has waived its entitlement to royalties
on gold production. These areas are not subject to the Mining Act 1978 (WA) and are instead
governed by the Hampton Regulations, which are administered by Hampton Gold Mining Areas. Both New
Hampton and South Kal conduct mining operations on the Hampton Lands under the auspices of special
leases issued to them by Hampton Gold Mining Areas in accordance with the Hampton Regulations.
Australian law generally requires that all necessary landowner title approval be obtained
before a mining lease can be granted and mining operations can commence. Mt. Magnet, New Hampton
and South Kal have approved mining leases for most of their reserves, including all reserves that
are currently being mined. If these companies wish to initiate mining operations in areas presently
held under exploration tenement, their relevant exploration tenements will need to be converted to
mining leases. This issuance of a mining lease requires the agreement of the affected landowner
title claimants, on terms either directly negotiated with them or otherwise determined in
accordance with the Native Title Act 1993. There can be no assurance that any approval would be
received.
Papua New Guinea
The Mining Act of 1992 (PNG) is based on Australian legislation. Accordingly, mineral rights
in PNG also belong to the government of PNG and they have a statutory right to obtain up to a 30%
participating interest in mining development projects. The government then issues and administers
mining tenements under the relevant mining legislation, and mining companies must pay royalties to
the government based on production.
The key difference in PNG is that citizens have the right to carry out non-mechanized mining
of alluvial minerals on land owned by them. These customary rights do not extend over a mining
lease, unless an alluvial mining lease is obtained.
Almost all land in PNG is owned by a person or group of persons, and is not generally overlaid
by landowner title issues. There is, however, considerable difficulty in identifying landowners of
a particular area of land because land ownership may arise from both contract and inheritance, and
because of the absence of a formal written registration system.
Prior to commencing exploration, compensation for loss or damage must be agreed with the
landowners. Prior to commencing mining, a written agreement must be entered into with landowners
dealing with compensation and other matters.
In PNG, Morobe Consolidated Goldfields Limited (Morobe") holds a mining lease and various
exploration licenses granted by the Department of Mining for the Hidden Valley Project. Morobe has
also entered into a memorandum of agreement with the state, local government and the landowners.
Wafi Mining Limited holds various exploration licenses granted by the Department of Mining for
the Wafi/Golpu Project, and has entered into a compensation agreement with landowners on one of its
exploration licenses.
In PNG there are no applicable exchange control restrictions but the PNG central bank does
have to be informed of all transactions and has to approve lending facilities and interests rates
charged.
Environmental Matters
South Africa
Harmony recognizes that the long-term sustainability of our business is as dependent on good
management of our environment as it is on the optimal extraction of our mineral resources. It is
our duty to assess environmental impacts and, where significant pollution or degradation may occur
as a result of our activities, to take reasonable measures to minimize these and to rectify any
impacts that have already been caused.
The overall objectives of Harmonys environmental management activities are to:
|
|
|
clean the surface environment after mining and ensure certificates of closure are
obtained; |
104
|
|
|
promote clean mining and minerals processing; |
|
|
|
|
support Harmonys social plan requirements, such as required by the MPRDA and Mining
Charter, Black Economic Empowerment (BEE) and local community involvement; |
|
|
|
|
reduce environmental liabilities by 10% per annum by optimising assets; and |
|
|
|
|
self-fund environmental rehabilitation through economic activities/savings, thus
contributing to the bottom line. |
|
|
Our approach to environmental management encompasses the following four broad principles: |
|
|
|
|
All relevant environmental risks should be identified and prioritized; |
|
|
|
|
Environmental issues should be dealt with promptly; |
|
|
|
|
Environmental issues, particularly relating to continuous non-compliance or potentially
serious environmental impacts, should be notified and dealt with at the board level; and |
|
|
|
|
we will adopt the best practicable environmental option; that is, the option that has
most benefit, or causes the least damage to the environment, at a cost acceptable to society
and affordable to us. |
Harmony developed its environmental policy in consultation with various stakeholders such as
mine managers, employees and unions, and which has the approval of the Chairman of the Sustainable
Development Committee and the Chief Executive. It has also been adopted by each mine manager
at signing ceremonies held at each shaft. It commits companies to returning their areas of
operation as close as possible to the pre-mining state, thus creating sustainability and economic
viability for generations to come. The main areas of the policy are:
|
|
|
That environmental management is a corporate priority; |
|
|
|
|
That environmental policies, programs and practices will be integrated into the
activities of Harmony; |
|
|
|
|
That we will strive for continued improvement and efficiency; |
|
|
|
|
That we will work with government departments and the public to come up with the best
sustainable solutions; |
|
|
|
|
That contractors and suppliers will be required to comply with the Harmony policy; and |
|
|
|
|
That employees will be informed and educated regarding their environmental
responsibilities. |
The focus was on implementing an environmental management policy at an operational level
during fiscal 2007. Harmony is in the process of adopting the ISO 14001 specification as the
Environmental Management System (EMS) for the South African operations. Previously the discipline
was managed through the development and implementation of an in-house EMS, based on the
Environmental Management Programme Reports (EMPRs). It was found, however, that this did not meet
the levels of governance required by the group. The EMS is a structured approach for addressing the
triple bottom line (social, economic and environmental) and forms the backbone of environmental
management at an operational level. ISO 14001 is a recognized and widely adopted EMS framework.
During fiscal 2007 a management company was appointed to assist with the implementation phase of
ISO 14001. To date the phased approach to introduce the system on a per site basis has progressed.
Doornkop Mine: the site specific team has been formed under the chairmanship of the General Manager
and a full aspect analysis has been completed and a detailed compliance audit completed. In the
execution of this site it has been established that the complexities of such a programme and the
timing for implementation on the other target sites will have to be extended to ensure the success
of the project Target and Elandsrand Mines: Steering committees have been set up at both mines
again under the leadership of the General Manager. The aspect/impact identification process has
been completed. Both areas are currently developing the Environmnetal Management Programmes (EMP)
for the significant impacts as identified during the above process.
105
In addition to the above sites, the Phakisa Mine has been added as a further first phase site as it
is a major project in the group and as such will form one of the backbones of the company going
forward into the future and will therefore be committed to fully complying with the companys
environmental policy.
The programme for implementation of the above four sites, which represent a cross section of the
companies activities, covering deep level mining and trackless type operations , is late 2008.
Environmental policy and strategy within Harmony, as well as the environmental impact of our
operations on regional communities, is overseen by the Sustainable Development Committee. The
management of environmental issues at operational level is the responsibility of each Chief
Operational Officer, who is supported by line management in the various regions. Structures and
reporting mechanisms have been put in place to ensure that the board is kept fully informed of
environmental matters within the group.
The Environmental Management Forum (EMF) has been structured to support operational goals.
Primarily, this means it will ensure reasonably practicable compliance with legislation, and the
promotion of environmental awareness. At a regional level, environmental management managers
provide advice and support to the relevant operational management teams. Given the diversity of the
environmental issues being dealt with, one of the environmental challenges facing the operations is
to effectively access the diverse range of skills necessary to address environmental issues.
Rehabilitation and mitigation capacity resides within the various operational functions, such as
surface engineering, metallurgy, etc. Where specific capacity is lacking in-house, use is made of
external consultants with appropriate specialist expertise. The process of rehabilitation has been
given a boost with the appointment of a group level Environmental Manager specifically charged with
accelerating the rehabilitation of specific target areas with a view to obtain concurrent closure
instead of the approach of viewing final mine closure at the end of life of mine. Operational
personnel are assisted by the EMF to determine the scope of work and consultants are selected and
employed as the need arises. Their selection is conducted in terms of the Harmony procurement
policy. Regional environmental managers meet on a quarterly basis as part of a process to encourage
networking, information sharing and joint problem-solving. Staff members are encouraged to develop
their skills through on-the-job training and external opportunities such as conferences and short
courses. Current complements provide for further strengthing of the skills base of the EMF in line
with our commitments.
Environmental management at Harmony is guided by the environmental policy, by prevailing
environmental laws and the EMPRs developed by Harmony for each operation and approved by the DME
which are legally binding. We are not aware of any litigation, current or pending, against Harmony
in this regard. During the fiscal year 2005, we were issued with directives from the Department of
Water Affairs and Forestry (DWAF) related to the collection, removal and re-use or disposal of
extraneous groundwater in the Klerksdorp, Orkney, Stilfontein and Hartebeestfontein (KOSH) area.
This follows the liquidation of the DRDGOLD North West operations in this area and the subsequent
liquidation of Stilfontein, which brought an end to their pumping activities and threatened to
flood other mines in the area. We continue to comply with the requirements of these directives and
are working with other mining companies AngloGold Ashanti and Simmer & Jack Mines Limited and
the various government departments the DME, DWAF and the Department of Environment and Tourism
(DEAT) to address the fundamental question of liability for defunct operations. In February
2007, Harmony, AngloGoldAshanti and Simmer Jack Mines Limited entered into an agreement pursuant to
which Margaret Water Company (MWC) has been formed to manage the water emanating from the now
defunct Stilfontein Gold Mine. The company, West Basin Environmental Corporation (WBEC) is
managed by directors appointed by each of the mining houses and is in the process of funding the
necessary infrastructure improvements to ensure the sustainability of the pumping operations. The
Western Utilities Corporation (WUC) has also been established in order to fund the treatment of
the water on a sustainable basis. WUC has secured sufficient offshore funding from offshore
investors and has entered into a management agreement with WBEC to engineer and build a pilot
plant.
MWC and the three mining companies have agreed to enter into a loan agreement for the
provision of a loan of R18.0 million (US$2.56 million) from each mining company to MWC as seed funding for
stabilization of the infrastructure. The three mining companies on behalf of MWC are currently
negotiating the acquisition of the assets necessary for pumping the water and intend to formalize
the existing service relationship with Buffelsfontein Mine who is currently acting as managers in
the water pumping process. Negotiations with the liquidator of Stilfontein Gold Mine are in the
final stages which will secure the necessary assets and staffing for the continued operation.
We also received a DWAF directive pertaining to the water management of the Western Mining
Void water decant. We currently comply with the regulators requirements within the operating
constraints of the water treatment plant. We are in regular contract with DWAF in this regard and
are currently minimizing the water discharge quantity by re-use in our metallurgical facilities.
The water treatment plant is being upgraded to improve the discharge water quality to enable us to
meet the prescribed water quality levels.
106
A further DWAF directive with regard to the apportionment of costs in regard to the Western
Basin decant was issued in December 2006 which was followed shortly after by an inter-mine
agreement between the recipients namely Harmony, Mintails SA and WestWits (DRDgold). This agreement
has led to the formation again of a section 21 company , named The West Basin Environmental
Corporation (WBEC) which in turn spawned the formation of an independently funded and managed
entity named The Western Utilities Corporation, who has secured funding for a pilot plant and
bankable feasibility study for the long term treatment of the decant water. This pilot plant is in
construction and is expected to be commissioned be the end of calendar 2007.In the interim the
parties to WBEC are sharing the costs and facilities to treat the water.
EMS forms the basis for the implementation of the environmental policy and monitoring
compliance. All of the South African operations function within the requirements and conditions of
the EMPRs that have been approved by the DME. These EMPRs contain specific as well as generic
principles relating to environmental management during the operation of the mine. Closure
objectives are set and closure plans formulated within the EMPR. The latter includes investigation
of the potential for re-use of existing infrastructure, preparation of a rehabilitation plan,
rehabilitation and vegetation of the affected area and post-closure monitoring. Conversion to new
order mining rights in line with the MPRDA requires that mining companies report on the extent of
compliance with their approved EMPRs. The EMPRs identify individual impacts, mitigation measures
and rehabilitation requirements. These have been used as the basis for the development of a
proprietary EMS, which is currently being tested, populated with information, and rolled out to the
various operations. This proprietary EMS, which encompasses the principles of ISO 14000, is an
electronic-based system. The proprietary EMS encompasses the following activities:
|
|
|
Environmental inspection: general inspections are performed routinely and systematically
with collected data entered into the system to enable follow-up actions. |
|
|
|
|
Risk assessment: detailed and specific risk assessments are conduced to help identify
deviations that may not have been otherwise anticipated. |
|
|
|
|
Stakeholder communication: all communication is managed and may result in action items
for the organization for which the stakeholder will require follow-up feedback. All such
communication is logged. |
|
|
|
|
Monitoring: impact monitoring is focused on collecting and analyzing environmental data
that may well result in follow-up actions. |
|
|
|
|
Licenses/permits: all details relating to licenses or permits can be registered in the
system. |
|
|
|
|
Major loss, incident and accident notification: when an incident occurs, initial
information about the incident is recorded to trigger a notification process. |
The bulk of the significant impacts at Harmony are historic, and are currently managed in
terms of site-specific procedures or codes of practice. Any major operational changes will, in
future, take cognizance of the Environmental Impact Assessment (EIA) process and adhere to the
outcomes of such studies. Furthermore, the continued development of EMSs, with respect to site
monitoring and risk assessment, will allow for the inclusion of specific evaluation criteria in the
decision-making process. We have conducted internal compliance assessments on all of our EMPRs.
Assessments and non-compliance areas are being addressed. The results of the compliance assessment
have been included in the application for conversion to new order mining rights.
In accordance with legislation, we have established seven independent environmental
rehabilitation trust funds to make adequate financial provision for the expected cost of
environmental rehabilitation at mine closure and for the discharge of our obligations and
contingency liability. Each operation estimates its expected environmental closure liability
annually and this estimated amount is used to calculate the contributions to be made to the
rehabilitation trust funds. The contributions are spread over the operational life-of-mine and
contributions are made by each operation on an annual basis. Even though the various investments in
the rehabilitation trust funds are pooled, each operational unit has its own account. The
accumulated amount in the various South African rehabilitation trust funds as at June 30, 2007 was
$189.1 million, while the total rehabilitation liability was $131.9 million in current monetary
terms.
The assets of each mine within each fund are ring-fenced and may not be used to
cross-subsidize one another. Contributions to the various funds will continue to be made over the
operations life-of-mine and each fund is expected to be fully-funded at the time of closure.
Sudden and accidental pollution is covered under our public liability insurance policy. The Asset
Management Committee formed during the 2006 fiscal year continues to co-ordinate the activities
related to the disposal of assets and subsequent closure of
107
redundant operational sites to an environmentally acceptable standard. The EMF is represented
on the committee at senior management level. An important element of this committees work is to
investigate alternative and appropriate land use, particularly in respect of those assets for which
closure is being planned.
Pursuant to South African law, mine properties must be rehabilitated upon closure. Mining
companies are required by law to submit EMPRs, to the Department of Minerals and Energy. EMPRs
identify the rehabilitation issues for a mine and must also be approved by other South African
government departments including, but not restricted to, the Department of Water Affairs and
Forestry.
EMPRs have been prepared and submitted for all of Harmonys South African operations. All of
Harmonys South African mining operations have permanent mining authorizations as required in terms
of the previous MPRDA. Harmony is currently in the process of converting these mining
authorizations to new order mining rights as required under the MPRDA. The application for the
Evander Operations has been submitted. Harmony has already obtained certain new order mining rights
and does not anticipate any difficulties in this regard. Harmony meets with and intends to continue
to meet on a regular basis with the relevant government departments to continue the information
sharing process that it has with them and to ensure the environmental impact of Harmonys mining
operations are managed in accordance with applicable regulatory requirements and industry
standards.
All water uses are now in the process of being licensed, and Harmony has submitted water-use
registrations required by the National Water Act of 1998. Harmony has also developed water
management plans for all of its South African operations. This process is now extended to a full
review and submission of Water Use Licence applications, which will take into account all
water-related issues as well as planned projects.
In addition, an environmental surveillance system has been implemented at slimes dams at
Harmonys operations to monitor dust generation and fall-out in residential and other areas. This
will assist in future dust suppression and the design and measurement of rehabilitation programs.
In excess of R5 million ($0.7 million) has been spent in contouring the tops of the slimes dams
concerned and to provide wind erosion containment measures and the supply of sewage discharge water
to initiate vegetation growth in the coming season has been completed. In addition, spraying of the
leading edges of the dams and dumps with eco-friendly palliatives to bind the soils in the short
term is ongoing, although the palliatives have had limited success in binding the dust particles,
further tests are ongoing.
Australia
Harmonys Western Australian operations are subject to applicable environmental legislation,
and also specific site conditions attaching to the mining tenements imposed by the Department of
Industry and Resources, to the operating licenses issued by the Department of Environmental
Protection, and also to the water abstraction licenses issued by the Water and Rivers Commission.
As a result, Harmony must make provision for environmental rehabilitation whenever mining
operations are conducted. While Harmony believes that its current provision for compliance with
such requirements is reasonable, any future changes and development in Australian environmental
laws and regulations may adversely affect these Australian operations. The total Australian
rehabilitation liability was $20.8 million (A$24.5 million) at the end of fiscal 2007.
In Western Australia, rehabilitation obligations under the Mining Act are covered by
environmental securities issued by Harmony, or by performance bonds issued by Harmonys bankers.
These bonds cannot be relinquished or cancelled without the approval of the Department of Industry
and Resources. The amount of the bond is established prior to issuance of the tenement and
commencement of operations, and generally is audited by the regional inspector. Thereafter, the
amount is reviewed on an annual basis following the issuance by Harmony of an annual environmental
report. As areas are successfully rehabilitated, the bond requirement is reduced.
Audits are generally conducted on a bi-annual basis by the Australian Department of
Environmental Protection to determine compliance with the relevant operating license(s). There are
currently no outstanding material non-compliance issues against Harmonys licenses.
At each of its mines, Harmony has appointed a person dedicated to environmental matters who,
in addition to organizing the implementation of the environmental management programs, monitors the
impact of mining on the environment and responds to impacts that require specific attention outside
of the normal program of environmental activities.
The primary environmental focus at most of Harmonys operations is water management and the
administration of areas outside the operating plants and shafts. The major objective is to ensure
that water is of a quality fit for use by downstream users.
108
Based on current environmental and regulatory requirements, Harmony accrues for the estimated
rehabilitation expense in full when mining commences and then amortizes these environmental
rehabilitation costs over the operating life of a mine.
Papua New Guinea
Harmonys PNG operations are in exploration, pre-feasibility study and project construction
phases, and mining has not yet commenced. Harmony is subject to applicable environmental
legislation including specific site conditions attaching to the mining tenements imposed by the PNG
Government Department of Environment and Conservation (DEC), to the terms and conditions of
operating licenses issued by the Department of Mines and DEC, and also to the environment permit
for water abstraction and discharge issued by DEC.
The current status of Harmonys PNG projects can be summarized as follows:
The Hidden Valley project is in the construction phase. The project has obtained and is in
compliance with all permits and licenses required for the current stage of the projects
development. The access road to the Hidden Valley project site has been completed with part of the
road sides successfully revegetated. The foundations have been completed for accommodation and
administration buildings for the general mine infrastructure. Excavation is underway for the plant
site, tailings storage facility and the access road to the open pit. Government approval has been
given to amend the environment permit based on an updated feasibility study for the site.
The Wafi Golpu project is presently undertaking pre-feasibility studies. The project has
obtained, and is in compliance with, all permits and licenses for the current stage of the
projects development.
Harmony PNG is committed to working within the framework of corporate EMS in accordance with
the international EMS standard, ISO 14001:2004, adapted for use in Australia and New Zealand as
AS/NZS ISO 14001:2004 and the Equator Principles of the World Bank. These standards provide Harmony
PNG with the elements of an effective EMS, that is, a procedure for implementing, achieving,
reviewing and maintaining Harmonys environmental policy, and also incorporates good industry
environmental management practices, which form the basis of a project-specific EMS.
An EMS is a structured approach to managing an environmental program, and provides a quality
system to guide:
|
|
|
development and implementation of environmental management procedures; |
|
|
|
|
monitoring of environmental impacts and performance; and |
|
|
|
|
review of procedures to ensure continual improvement. |

Health and Safety Matters
South Africa
The Mine Health and Safety Act
For many years, the safety of persons working in South African mines and quarries was
controlled by the Mines and Works Act of 1956 and then by the Minerals Act of 1991 which was
replaced by the Mine Health and Safety Act of 1996. The Minerals Act of 1991 has subsequently been
repealed and the Mineral and Petroleum Resources Development Act of 2002 (MPRDA) promulgated. The
findings of the Leon Commission of Inquiry into Health and Safety in the Mining Industry (held in
April 1994) culminated in the Mine Health and Safety Act of 1996, which was a product of intensive
discussion and debate between government, employers and employee representatives over an extended
period of time. The objectives of the Mine Health and Safety Act are:
|
|
|
to protect the health and safety of employees and other persons at mines; |
|
|
|
|
to promote a culture of health and safety; |
|
|
|
|
to require employers and employees to identify hazards and eliminate, control and
minimize the risks relating to health and safety at mines; |
|
|
|
|
to give effect to the public international law obligations of South Africa that concern
health and safety at mines; |
|
|
|
|
to provide for employee participation in matters of health and safety through health and
safety representatives and health and safety committees at mines; |
|
|
|
|
to provide for the effective monitoring of health and safety conditions at mines; |
|
|
|
|
to provide for the enforcement of health and safety measures at mines; and |
|
|
|
|
to foster and promote co-operation and consultation on health and safety between the
Department of Minerals and Energy, employers, employees and their representatives. |
The Mine Health and Safety Act prescribes general and specific duties for employers and
others, determines penalties and a system of administrative fines, and provides for employee
participation by requiring the appointment of health and safety representatives and the
establishment of health and safety committees. It also entrenches the right of employees to refuse
to work in dangerous conditions. Finally, it describes the powers and functions of the mine health
and safety inspectorate and the process of enforcement.
Government, through the Department of Minerals and Energy, ordered the institution of audit
teams to conduct legal compliance and systems audits on mines across all commodities.
It is anticipated that mining companies will incur additional expenditure in order to comply
with the prescribed legislative requirements. Management anticipates that such additional
expenditure will not have a material adverse effect upon Harmonys operational results or financial
condition.
HIV/AIDS Policy
Harmony is actively pursuing holistic HIV/AIDS awareness campaigns with its South African
workforce and is also providing medical assistance and anti-retroviral treatment. Employees who
decide to leave their place of work and return home for care are cared for at their homes through
the TEBA home based care system, to which Harmony contributes. See Risk Factors Risks Relating
to Our Business and Our Industry HIV/AIDS poses risks to Harmony in terms of productivity and
costs and Risk Factors Risks Relating to Our Business and Our Industry The cost of
occupational healthcare services may increase in the future.
In South Africa, Harmony has an agreement with the relevant stakeholders concerning the
management of HIV/AIDS in the workplace. This agreement, originally signed in 2002 with the
National Union of Mine Workers (NUM) and the United Association of South Africa (UASA) was
amended for the third time in August 2006. While many aspects of the policy have remained
unaltered, the most fundamental change is the inclusion in the policy of a broad spectrum of
chronic manageable diseases other than
110
HIV/AIDS such as diabetes and hypertension. Harmony has done this in the hope of doing more to
take the stigma away from the disease and encouraging people to see it for what it is Harmony
believes AIDS can be managed through the proper use of medication. The agreement is also used as a
marketing tool to encourage employee participation in the Harmony HIV/AIDS Program.
Harmonys HIV/AIDS Program, which is fully supported by management, is overseen by a qualified
medical practitioner, together with the assistance of qualified consultants and experts. In
September 2005, an independent consultant, the Health Monitor Group undertook a business impact
assessment for the group. Based on actuarial information, it appears that the prevalence rates of
HIV/AIDS within Harmony have stabilized at around 30%. The introduction of Highly Active
Anti-Retroviral Therapy has also helped to manage the treatment of HIV/AIDS infected employees. The
effectiveness of these measures will only be determined over time. We are currently negotiating an
agreement on the Traditional Health Practitioners with the NUM and we have a contracted a dually
qualified Western Doctor/Traditional Health Practitioner who attends to patients once weekly at the
clinic in Randfontein and also advises us in view of the pending National Traditional Health
Practitioners Bill.
In the 2007 fiscal year, there were 52 documented AIDS related deaths as compared to 49 in
2006 and 66 in 2005. In addition, 783 employees left as a result of medical repatriation as
compared to 1,572 in 2006 and 1,611 in 2005. Medical repatriations refer to those employees who are
not sufficiently well to continue working and are thus provided with an early and humane exit from
Harmony.
Harmony embarked upon a holistic and integrated campaign in fiscal 2007 in which approximately
R14.0 million ($1.9 million) was spent.
Australia
Australia has a well regulated system of occupational health and safety, comprised of
legislation and regulations in each of its states. Several of these specifically apply to the
mining industry, including extensive codes of practice and guidelines. There is also a well
developed certification and licensing system for employees and the usage of certain items of
equipment. The legislation and regulations governing this area include the Australian Standards
4804, the Safety Management Systems and the Western Australian Mining Regulation Act 1994, the
Occupational Safety and Health Act 1984 (WA), the Occupational Safety and Health Regulations 1996,
the Mines Safety and Inspection Act 1994 (WA) and the Mines Safety and Inspection Regulations 1995.
In the event of injury while at work, employees are protected by a compulsory workers
compensation scheme.
Harmony currently believes that the prevalence of HIV/AIDS-related diseases among its
Australian workforce is not material to its Australian operations.
Papua New Guinea
PNG has a significant mining industry, and a developing system of occupational health and
safety. The Mining (Safety) Act of 1977 (PNG) is the principal legislation that addresses a range
of issues such as working hours, minimum safety and reporting requirements. Other legislation and
regulations also apply.
As Harmony is currently building its first mine in PNG, the occupational health and safety
standards for the mine are undergoing development.
Although reliable statistics with regard to infection rates are not readily available,
preliminary results indicate that Papua New Guinea is in the early stages of an AIDS pandemic. As
part of the development of the Hidden Valley project, and other exploration activities carried out
by Harmony in PNG, Harmony has rolled out a health care strategy for its employees to increase Aids
awareness. See Risk Factors Risks Relating to Our Business and Our Industry HIV/AIDS poses
risks to Harmony in terms of productivity and costs and Risk Factors Risks Relating to Our
Business and Our Industry The cost of occupational healthcare services may increase in the
future".

Item 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS
You should read the following discussion and analysis together with the consolidated financial
statements, including the related notes, appearing elsewhere in this annual report.
Overview
We conduct underground and surface gold mining and related activities, including exploration,
processing, smelting and beneficiation. Our operations have grown significantly since 1995, largely
through acquisitions. Since 1995, Harmony has expanded from a lease-bound mining operation into an
independent world-class gold producer. We are currently the third largest producer of gold in South
Africa, producing some 19.7% of the countrys gold output, and the fifth largest gold producer in
the world. Harmonys gold sales have increased from 650,312 ounces of gold in fiscal 1995 to
approximately 2.3 million ounces of gold in fiscal 2007. As at June 30, 2007, Harmonys mining
operations reported total proven and probable reserves of approximately 53.67 million ounces and in
fiscal 2007, we processed approximately 22.8 million tons of ore.
We manage and evaluate our operations on a shaft-by-shaft basis. The South African underground
operations are treated as three separate reporting segments for management and reporting purposes.
We have found this system to be very effective as, among other things, it allows for different
management styles and capital allocations.
These three segments are:
|
|
|
the Quality Assets, which typically have a larger reserve base and hence a longer life.
These form the core of our operations; |
|
|
|
|
the Leveraged Assets are those that provide significant upside in the event of a rising
gold; and |
|
|
|
|
the Growth Assets, which comprise the expansion projects/new mines currently being
constructed in South Africa. |
In addition, there are a number of surface operations.
Our South African operations are categorized as follows:

Critical Accounting Policies And Estimates
The preparation of our financial statements requires management to make estimates and
assumptions that affect the reported results of our operations. Actual results may differ from
those estimates. Harmony has identified the most critical accounting policies upon which its
financial status depends. Some of Harmonys accounting policies require the application of
significant judgment and estimates by management in selecting the appropriate assumptions for
calculating financial estimates. By their nature, these judgments
112
are subject to an inherent degree of uncertainty and are based on Harmonys historical
experience, terms of existing contracts, managements view on trends in the gold mining industry
and information from outside sources.
Harmonys significant accounting policies are described in more detail in note 2 to the
consolidated financial statements. This discussion and analysis should be read in conjunction with
the consolidated financial statements and related notes included in reporting Item 18. Financial
Statements. Harmonys management has identified the following as critical accounting policies
because estimates used in applying these policies are subject to material risks and uncertainties.
Harmonys management believes the following critical accounting policies, together with the other
significant accounting policies discussed in the notes to the consolidated financial statements,
affect its more significant judgments and estimates used in the preparation of the consolidated
financial statements and could potentially impact Harmonys financial results and future financial
performance.
Depreciation and Amortization of Mining Assets
Depreciation and amortization expense is calculated using the units of production method and
is based on Harmonys current gold production as a percentage of total expected gold production
over the lives of Harmonys mines. A unit is considered to be produced for U.S. GAAP purposes at
the time it is physically removed from the mine. The lives of the mines are estimated by Harmonys
geology department using proven and probable mineral reserves, as determined in accordance with the
SECs Industry Guide Number 7. The resultant depreciation and amortization expense is then
classified as inventory and subject to inventory valuation under U.S. GAAP.
The estimate of the total expected future lives of Harmonys mines could be materially
different from the actual amount of gold mined in the future and the actual lives of the mines due
to changes in the factors used in determining Harmonys mineral reserves, such as the gold price,
foreign currency exchange rates, working costs and working rates (continuous operations mining). We
regularly review the lives of the mines and economic capacity of those assets with reference to any
events or circumstances that may indicate an adjustment is needed. Given the significance of mining
assets to our financial statements, any changes to the life of mine could have a material impact on
the annual amortization charge and materially impact on our results of operations and financial
conditions. See Item 3. Key Information Risk Factors Harmonys gold reserve figures are
estimated based on a number of assumptions, including assumptions as to mining and recovery
factors, future cash costs of production and the price of gold and may yield less gold under actual
production conditions than currently estimated.
Business Combinations
Harmony accounts for its business acquisitions under the purchase method of accounting. The
total value of consideration paid for acquisitions is allocated to the underlying net assets
acquired, based on their respective estimated fair values determined by us using internal or
external valuations. We use a number of valuation methods to determine the fair value of assets and
liabilities acquired including discounted cash flows, external market values, valuations on recent
transactions or a combination thereof and others and believes that it uses the most appropriate
measure or a combination of measures to value each asset or liability. In addition, we believe that
we use the most appropriate valuation assumptions underlying each of those valuation methods based
on current information available including discounted rates, market risk rates, entity risk rates,
cash flow assumptions and others. The accounting policy for valuation of business acquisitions is
considered critical because judgments made in determining the estimated fair value and expected
useful lives assigned to each class of assets and liabilities acquired can significantly impact the
value of the asset or liability, including the impact on deferred taxes, the respective
amortization periods and ultimately net profit. Therefore, the use of other valuation methods, as
well as other assumptions underlying these valuation methods, could significantly impact the
determination of financial position and results of operations.
Carrying Value of Goodwill
Harmony evaluates, on at least an annual basis, the carrying amount of goodwill to determine
whether current events and circumstances indicate that such carrying amount may no longer be
recoverable. To accomplish this, Harmony compares the fair values of its reporting units to their
carrying amounts. If the carrying value of a reporting unit were to exceed its fair value at the
time of the evaluation, Harmony would compare the implied fair value of the reporting units
goodwill to its carrying amount and any shortfall would be charged to statements of operations.
Assumptions underlying fair value estimates are subject to risks and uncertainties. If these
assumptions change in future, we may need to record impairment charges on goodwill not previously
recorded.
113
Impairment of Long-Lived Assets
Harmony reviews and evaluates its long-lived assets for impairment when events or changes in
circumstances indicate the related carrying amounts may not be recoverable. An asset impairment is
considered to exist if the total estimated future cash flows on an undiscounted basis are less than
the carrying amount of the asset, including goodwill, if any. An impairment loss is measured and
recorded based on discounted estimated future cash flows. Future cash flows are estimated based on
estimated quantities of recoverable minerals, expected gold prices (considering current and
historical prices, price trends and related factors), production levels and cash costs of
production, capital and reclamation costs, all based on detailed life-of-mine plans. The
significant assumptions in determining the future cash flows for each individual operating mine at
June 30, 2007, apart from production cost and capitalized expenditure assumptions unique to each
operation, included a long-term gold price of $520 per ounce and South African and Australian
dollar exchange rates of $1 = R6.88 and A$1 = $0.73, respectively. The term recoverable minerals
refers to the estimated amount of gold that will be obtained from proven and probable reserves and
related exploration stage mineral interests, except for other mine-related exploration potential
and greenfields exploration potential discussed separately below, after taking into account losses
during ore processing and treatment. Estimates of recoverable minerals from such exploration stage
mineral interests are risk adjusted based on managements relative confidence in such materials.
With the exception of other mine-related exploration potential and greenfields exploration
potential, estimates of future undiscounted cash flows are included on an area of interest basis,
which generally represents an individual operating mine, even if the mines are included in a larger
mine complex. In the case of mineral interests associated with other mine-related exploration
potential and greenfields exploration potential, cash flows and fair values are individually
evaluated based primarily on recent exploration results and recent transactions involving sales of
similar properties.
As discussed above under Depreciation and amortization of mining assets, various factors
could impact Harmonys ability to achieve its forecasted production schedules from proven and
probable reserves. Additionally, gold prices, capital expenditure requirements and reclamation
costs could differ from the assumptions used in the cash flow models used to assess impairment. The
ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral
interests involves further risks in addition to those factors applicable to mineral interests where
proven and probable reserves have been identified, due to the lower level of confidence that the
identified mineralized material can ultimately be mined economically. Assets classified as other
mine-related exploration potential and greenfields exploration potential have the highest level of
risk that the carrying value of the asset can be ultimately realized, due to the still lower level
of geological confidence and economic modelling.
During the years ended June 30, 2007, 2006 and 2005, write-downs of long-lived assets of the
continuing operations were $10.2 million, $15.9 million and $122.8 million, respectively. Material
changes to any of these factors or assumptions discussed above could result in future impairment
charges.
Hedging and Financial Derivatives
Harmony accounts for its derivative financial instruments in accordance with Statement of
Financial Accounting Standards (SFAS) No. 133. See Item 11. Quantitative and Qualitative
Disclosures About Market Risk General. The determination of the fair value of hedging
instruments and financial derivatives, when marked to market, takes into account estimates such as
projected commodity prices, interest rates and foreign currency exchange rates under prevailing
market conditions, depending on the nature of the hedging and financial derivatives. These
estimates may differ materially from actual commodity prices, interest rates and foreign currency
exchange rates prevailing at the maturity dates of the hedging and financial derivatives and,
therefore, may materially influence the values assigned to the hedging and financial derivatives,
which may result in a charge to or an increase in Harmonys earnings at the maturity dates of the
hedging and financial derivatives.
Remediation Obligations (Asset Retirement Obligations)
Harmonys mining and exploration activities are subject to various laws and regulations
governing the protection of the environment. In August 2001, the FASB issued SFAS No. 143,
Accounting for Asset Retirement Obligations, which established a uniform methodology for
accounting for estimated reclamation and abandonment cost. The reclamation costs are allocated to
expense over the life of the related assets and will be adjusted for changes resulting from the
passage of time and revisions to either the timing or amount of the original present value
estimate.
Prior to adoption of SFAS No. 143, estimated future reclamation costs were based principally
on legal and regulatory requirements. Such costs related to active mines were accrued and charged
over the expected operating lives of the mines using the units of production method based on proven
and probable reserves.
114
Accounting for reclamation and remediation obligations requires management to make estimates
unique to each mining operation of the future costs we will incur to complete the reclamation and
remediation work required to comply with existing laws and regulations. Actual costs incurred in
future periods could differ from amounts estimated. Additionally, future changes to environmental
laws and regulations could increase the extent of reclamation and remediation work required to be
performed by us. Any such increases in future costs could materially impact the amounts charged to
operations for reclamation and remediation.
For more information regarding the environmental regulations applicable to Harmonys
operations, see Item 3. Key Information Risk Factors Harmonys operations are subject to
extensive government regulations, and Item 3. Key Information Regulation Environmental
Matters.
Deferred Tax Asset
We recognize a valuation allowance against our deferred tax assets when it is more likely than
not that the asset will not be utilized. Assessing recoverability of deferred tax assets requires
management to make significant estimates related to expectation of future taxable income. Estimates
of future taxable income are based on forecasted cash flows from operations, reversals of deferred
tax liabilities and the application of existing tax laws in each jurisdiction. To the extent that
future taxable income differs significantly from estimates, our ability to realize the net deferred
tax assets recorded at the balance date could be impacted. Additionally, future charges in tax laws
in the jurisdictions in which we operate could limit our ability to obtain the future tax benefits
represented by deferred tax assets recorded at the balance date.
Revenue
Substantially all of Harmonys revenues are derived from the sale of gold. As a result,
Harmonys operating results are directly related to the price of gold. Historically, the price of
gold has fluctuated widely. The gold price is affected by numerous factors over which Harmony does
not have control. See Item 3. Key Information Risk Factors The profitability of Harmonys
operations, and the cash flows generated by those operations, are affected by changes in the market
price for gold, which in the past has fluctuated widely.
As a general rule, Harmony sells the gold it produces at market prices to obtain the maximum
benefit from prevailing gold prices and does not enter into hedging arrangements such as forward
sales or derivatives that establish a price in advance for the sale of its future gold production.
A substantial proportion of the production at each of New Hampton and Hill 50 was already
hedged when acquired by Harmony. In fiscal 2002, in line with Harmonys strategy of being generally
unhedged, Harmony reduced New Hamptons hedge book by over 900,000 ounces. In fiscal 2002, Harmony
also combined and restructured the overall hedge portfolio of Harmonys Australian operations
(which include New Hampton and Hill 50), after which
