VANCOUVER, British Columbia, July 08, 2025 — West Red Lake Gold Mines Ltd. (“West Red Lake Gold” or the “Company”) (TSXV:WRLG) (OTCQB:WRLGF) is pleased to announce the positive results of a Preliminary Economic Assessment (“PEA”) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) for a toll milling mine operation at its 100%-owned Rowan project in the Red Lake Gold District of northwestern Ontario, Canada (“the Rowan Project”).

All dollar amounts in this news release are in Canadian dollars unless otherwise indicated.

The effective date of the PEA is June 30^th, 2025, and a technical report relating to the PEA (the “Technical Report”) will be filed on SEDAR+ within 45 days of this news release.

Rowan PEA Highlights:

• High-Grade Efficient Mine: Underground mine via long hole retreat method, delivering an average diluted head grade of 8.0 grams per tonne (“g/t”) gold (“Au”), accentuated by 10.4 g/t Au average grade in Year 1.
• Notable Production: 35,230 oz. average annual Au production over the 5-year mine life from an average mining rate of 385 tonnes per day (“tpd”).
• Strong Value: $125.3M post-tax Net Present Value (“NPV”) at US$2,500 per oz Au. Post-tax NPV rises to $239M at US$3,250 per oz Au.
• Low Costs and Strong Returns: US$1,408/oz all-in sustaining cost (“AISC”) and 41.9% post-tax internal rate of return (“IRR”), underscoring the viability of the Company’s second potential mine in the region. IRR increases to 81.7% at a US$3,250/oz gold price.
• Modest Initial Capital: Multiple mills in the area with excess capacity create the opportunity to develop Rowan as a toll milling operation with initial capital of just over $70 million.
• High Confidence Inventory: PEA mine design includes 63% of mined tonnes and 72% of mined ounces from the Indicated category – provides solid base for transition into prefeasibility study (“PFS”) level assessment.
• Simple Metallurgy: Free gold-dominant mineralization resulting in 75.8% to 94.9% gold recovery through gravity processing during metallurgical test work, which also supports toll milling potential.
• Development and Permitting Timeline: The Company plans to complete a Pre Feasibility Study (“PFS”) on the Rowan Project by Q3 2026, to continue advancing this valuable opportunity. The final year of 3-year baseline environmental data collection period is underway and the Company has been engaging with the regulators to support an expedited permitting process.  New Bill 5 legislation in Ontario is intended to speed up the mine approval process.  The WRLG team will work with the regulators and its Indigenous partners to permit and construct the Rowan Mine.
• Significant Exploration and Growth Potential: There are multiple opportunities to define additional mineralization at Rowan by (1) expansion drilling on the two main veins of the deposit included in this PEA mine plan (v001 and v004) especially at depth, (2) infill and expansion drilling on parallel veins adjacent to the PEA mine plan with data gaps stemming from selective historic drill sampling, (3) drill testing expansion targets along strike from the Rowan vein system, and (4) testing high potential new targets at the property including Apex and Big Bend.

“Rowan is a high grade, relatively wide, nearly vertical deposit that starts at surface and this PEA captures how such designed-for-mining characteristics lead to strong economics,” said Shane Williams, President and CEO. “There is ample opportunity to grow the resource further at Rowan along strike, at depth, and via discovery at new nearby targets, but we ideally want to do that work while turning this asset into a mine sending high-grade mineralization to an operating mill in the area and potentially generating significant revenue for the Company.

“A NPV of $239 million at close-to-spot gold pricing provides a compelling case to advance Rowan swiftly from here. We plan to advance engineering work while completing a drill program to infill gaps that prevented parts of the resource from being considered in the mine plan and upgrade roughly 37% of the mine plan tonnes that currently sits within the inferred resource category. That work will inform and maximize the value outlined in a PFS that we target issuing within 12 months that would be completed in tandem with permitting efforts at Rowan. It is also positive that the recent enactment of Bill 5 in Ontario creates potential for a simplified, collaborative, and expedited permitting process.”

The PEA was prepared by independent consultants Fuse Advisors, with input from Sims Resource LLC (resource estimate and modeling), Knight Piesold (tailings and waste rock), Integrated Sustainability Inc (water treatment), and PHC Inc (underground geotechnical).

Upside Potential

There are multiple opportunities to potentially expand and upgrade the resource and mine plan at Rowan.

The Rowan resource comprises 26 domains that capture multiple parallel veins. Three of those veins – v001, v003 and v004 – are mined in the PEA. A fourth vein with strong gold grades, called v006b, is the third largest contributor of tonnes and ounces in the current mineral resource estimate (“MRE”) but was not included in the PEA mine plan because its data stems largely from historic drilling, which suffers from unsampled intervals. Historic operators often only sampled and assayed drill core with visible quartz veining. Surrounding rock, including vein margins, narrow gaps between veins, and adjacent wall rock, was not sampled. In the MRE estimation process those unsampled intervals were assigned a value of half detection limit (0.0025 gpt Au).

During the 2023 drill campaign, West Red Lake Gold demonstrated that gold mineralization regularly persists into the altered wall rock adjacent to high-grade gold veins. Selective sampling would have missed mineralization of this type.

Lack of assay coverage outside of narrow sampled vein intervals resulted in a heavily diluted v006b resource with insufficient continuity for mining. The Company believes there is good potential to upgrade and expand v006b with approximately 2,000 metres of new drilling to re-drill some historic holes while also testing some strong targets for expansion and is keen to complete this work and potentially bring v006b into mine plan consideration. The position of v006b is also fortuitous as this area is closer to the mine portal and access decline and could potentially bring earlier tonnes and ounces into the mine plan within the first 6 months of development.

The planned drill program also includes holes to upgrade the 37% of the resource tonnes in the PEA mine plan that are currently categorized as inferred. It is notable that 63% of the resource tonnes and 72% of the ounces mined in the PEA plan are already at indicated confidence. Together, the drill program to upgrade portions v001 and v004 from inferred to indicated and upgrade v006b continuity totals 3,500 metres.

The next layer of opportunity at Rowan is based on expanding the deposit. Notably, the highest-grade intercept ever drilled at Rowan was achieved during the 2023 drill campaign when hole RLG-23-163B returned 70.8 g/t gold over 8.3 metres. This intercept came from the deeper portion of v001 and indicates potential for mineralization to continue, and perhaps strengthen, at depth. The Rowan vein system has only been defined down to approximately 400 metres and remains wide open for expansion at depth (Figure 2). The Rowan deposit also remains open along strike to the east and west.

Additionally, West Red Lake Gold defined two new till anomalies at Rowan in 2024 that align spatially with deflections and folding in the main regional shear that hosts gold mineralization. These targets have seen very little previous drilling (Figure 3).

Mining and Infrastructure

Rowan is planned as an underground operation mined by longhole stoping methods, tapping a deposit that is near vertical and averages 2 metres width.

The site requires 1.4 kilometres of capital development (including remucks, sumps, and level access points) before first ore is accessed. The mine plan starts in a high-grade portion of the deposit close to surface, resulting in a 10.4 g/t gold average head grade in Year 1. Head grade ranges from 6.7 to 7.4 g/t gold in Years 2, 3, and 4 as mining progresses through different parts of the three veins – v001, v003 and v004 – that make up the mine plan.

In Year 5 the mine reaches the deepest part of the mine plan and the grade rises to 9.9 g/t gold. Annual gold production ranges from 26,090 oz. to 41,410 oz. based primarily on the variance in head grade.

Material is moved out of the mine by truck.

A sampling tower will be used to measure the head grade before mined material is trucked off site for processing at a local mill.

Initial, Operating and Sustaining Capital

Initial capital needs are relatively evenly spread across three requirements: underground development to access mining areas, surface infrastructure, and equipment procurement. Capital spend estimates include a 30% contingency.

Surface infrastructure needs include a crusher, a sampling tower, polishing pond and water treatment plant, a waste rock facility, a mine dry facility, a small camp, a maintenance shop, and electrical infrastructure.

Operating costs were informed using the operating costs at mines in the area and include a 10% contingency.

A toll milling cost of $67.44 per tonne was assumed, based on first principle estimates as applied to toll milling agreements and knowledge of processing costs at mills in the vicinity.

Financial Analysis

The Rowan mine’s flagship characteristics are low capital costs and high gold grades. These attributes generate a toll milling mine plan with a 41.9% after-tax IRR and $42 million in expected average annual free cash flow.

Table 3: Key Operating, Cost, and Revenue Metrics at US$2,500 per oz. gold

The financial outcomes of the Rowan mine plan are highly sensitive to the price of gold. A 15% increase in the gold price to US$2,875 per oz. lifts the post-tax NPV and IRR to $176 million and 50.5%, respectively. A 30% increase in the gold price to US$3,250 per oz. (close to current spot pricing) leads to a $232 million NPV and a 66.6% IRR.

Technical Information

The PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. The Company has not defined any mineral reserves for the Rowan Project. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
