American Creek's JV Partner Tudor Gold Announces Filing of NI 43-101 Technical Report on the Updated Mineral Resource Estimate for the Goldstorm Deposit at the Treaty Creek Joint Venture Project, Located in the Golden Triangle of British Columbia

Cardston, Alberta--(Newsfile Corp. - May 2, 2023) - American Creek Resources Ltd. (TSXV: AMK) (OTCQB: ACKRF) ("the Corporation" or "American Creek") is pleased to report that project operator and JV partner Tudor Gold announced the filing of the technical report (the "Report") for the updated Mineral Resource Estimate on the Goldstorm Deposit (the "MRE" or "2023 Treaty Creek MRE") at their flagship Treaty Creek Project (the "Project") located in the Golden Triangle region of British Columbia. The Report is entitled "NI-43-101 Technical Report for the Treaty Creek Project", with an effective date of April 28, 2023 and was prepared for Tudor Gold by Garth Kirkham Geosystems and JDS Energy & Mining Inc.

• The Goldstorm Deposit remains open to the south, north, northeast and at depth.

Table 1: Summary of Indicated and Inferred Mineral Resource as of March 15, 2023^1-5

1. Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
2. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
3. The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.
4. The Mineral Resource Estimate was prepared for a potential open pit scenario using a constrained pit shell (with 50-degree slopes) at a 0.5 g/t gold equivalent cut-off grade and an underground mining scenario using a 0.7 g/t gold equivalent cut-off grade. Cut-off grades were derived from US$ 1,800/oz gold, US$ 20/oz silver, US$ 3.50/lb copper, CAD:USD of 0.77, C$ 2.50/tonne open pit and C$7.50 underground mining cost, C$ 38.50/tonne milled processing costs, C$ 1.50/tonne G&A cost, and process recoveries of 90 % for gold, 80 % for copper, and 80 % for silver.
5. AuEQ g/t = Au g/t + (Ag g/t*0.0098765) + (Cu ppm*0.0001185)

The Goldstorm sensitivity tables (Tables 2 and 3) report the variation of resource grade and tonnage with respect to the change in cut-off grades for the Indicated and Inferred Mineral Resources.

Table 2: Indicated Mineral Resource Cut-off Sensitivity - Combined Pit and Underground¹

1. Refer to footnotes to the Mineral Resource Estimate in Table 1 of this News Release.
2. The MRE utilizes 0.5 g/t AuEQ for the pit-constrained Mineral Resource and 0.7 g/t AuEQ for the underground Mineral Resource.

Table 3: Inferred Mineral Resource Cut-off Sensitivity - Combined Pit and Underground¹

1. Refer to footnotes to the Mineral Resource Estimate in Table 1 of this News Release.
2. The MRE utilizes 0.5 g/t AuEQ for the pit-constrained Mineral Resource and 0.7 g/t AuEQ for the underground Mineral Resource.

The Goldstorm Deposit consists of six mineral domains with unique geological characteristics. Five of the domains are gold-dominant with lesser proportions of silver and copper. Domain CS-600 is dominantly gold and copper rich, with lesser silver. The CS-600 hosts the majority of the copper at the Goldstorm Deposit and consists of a well-defined intrusive porphyry system. Table 4 summarizes the Indicated and Inferred Mineral Resources for each mineral domain.

Table 4: Mineral Resource by Domain - Combined Pit and Underground¹

1. Refer to footnotes to the Mineral Resource Estimate in Table 1 of this News Release.
2. A mineral estimate of the material within the defined pit that exists outside of the outlined mineral domains was completed and is included within the Inferred Mineral Resource, and listed "In Pit, External".

About Treaty Creek

The Treaty Creek Project hosts the Goldstorm Deposit, a large gold-copper porphyry system, as well as several other mineralized zones. As disclosed in the March News Release, the Goldstorm Deposit has an Indicated Mineral Resource (as defined in NI 43-101) of 23.37 Moz of AuEQ grading 1.13 g/t AuEQ (18.75 Moz gold grading 0.91 g/t, 2.18 Blbs copper grading 0.15 %, 112.4 Moz silver grading 5.45 g/t) and an Inferred Mineral Resource (as defined in NI 43-101) of 7.35 Moz of AuEQ grading 0.98 g/t AuEQ (5.54 Moz gold grading 0.74 g/t, 0.85 Blb copper grading 0.16 %, 45.08 Moz silver grading 5.99 g/t), with a pit constrained cut-off of 0.5 g/t AuEQ and an underground cut-off of 0.7 g/t AuEQ. The Goldstorm Deposit has been categorized into three dominant mineral domains and several smaller mineral domains. The CS-600 domain largely consists of an intermediate intrusive stock and hosts the majority of the copper mineralization within the Goldstorm Deposit. CS-600 has an Indicated Mineral Resource of 9.86 Moz AuEQ grading 1.10 g/t AuEQ (6.22 Moz gold grading 0.70 g/t, 1.98 Blbs copper grading 0.32 %, 51.1 Moz silver grading 5.71 g/t) and an Inferred Mineral Resource of 3.71 Moz AuEQ grading 1.19 g/t AuEQ (2.32 Moz gold grading 0.75 g/t, 0.76 Blb copper grading 0.36 %, 18.71 Moz silver grading 6.01 g/t). The Goldstorm Deposit remains open in all directions and requires further exploration drilling to determine the size and extent of the deposit.

Treaty Creek JV Partnership

American Creek is a proud partner in the Treaty Creek Project.

The project is a Joint Venture with Tudor Gold owning 3/5th and acting as operator. American Creek and Teuton Resources each have a 1/5th interest in the project creating a 3:1 ownership relationship between Tudor Gold and American Creek.

American Creek and Teuton hold fully carried 20% interests, which means no development costs are incurred by these companies until a production notice is issued. This gives shareholders a unique opportunity, to avoid the dilutive effects of exploration while maintaining their full 20% exposure to one of the world's most exciting mega deposits.
