FOREMOST CLEAN ENERGY ANNOUNCES 2,500 METRE DRILL PROGRAM AT ITS JEAN LAKE GOLD-LITHIUM PROPERTY

Foremost Clean Energy Ltd. will commence an up-to-20-hole 2,500-metre diamond drill program this month at its 100-per-cent-owned Jean Lake gold-lithium property, located near the historic mining centre of Snow Lake in Manitoba. This program is strategically designed to capitalize on record-high gold prices by expanding known high-grade gold and lithium mineralization identified in the 2022-2023 drill campaign. The drill program will run concurrently with the company's continuing drilling at its Murphy Lake South uranium property. The company believes this multipronged operational strategy provides shareholders with leveraged exposure to the exciting gold market, maximized operational efficiency and potential value creation.

Foremost's president and chief executive officer, Jason Barnard, comments:

"With gold achieving historic highs by surpassing $3,680 (U.S.) per ounce, we made a strategic decision to maximize shareholder value by capitalizing on an extraordinary market opportunity. We are mobilizing a drill program at our 100-per-cent-owned Jean Lake asset to expand its known high-grade gold and lithium mineralization. This initiative runs concurrently with an ongoing drill program on proven uranium mineralization at our Murphy Lake South project in the Athabasca basin.

"Our multiasset model is designed for exactly this scenario. While uranium continues to anchor our long-term vision in the face of transformative global demand, these parallel drill programs provide exceptional, capital-efficient leverage. We are not diverting focus; we are amplifying it. We are going to commence actively drilling on not one, but two highly prospective properties. With Jean Lake now fully owned and requiring minimal sustaining capital, it provides Foremost with significant optionality and value for our shareholders, aligning with our steadfast commitment to nuclear fuels and other critical energy minerals."

The Jean Lake property is situated within the prolific Flin Flon-Snow Lake greenstone belt, a geological terrain renowned for its significant gold endowment and emerging lithium potential. The previous program successfully intersected gold mineralization in eight drill holes, with intercepts extending from surface to a depth of 110 metres. Notable results include an intercept of 7.5 grams per tonne (g/t) gold (Au) over 7.66 metres (m), which contains a spectacular high-grade zone of 102 g/t Au over 0.48 metre, located approximately 65 metres below surface (see news release dated June 6, 2023).

Key highlights:

• Drill program will commence later this month concurrently with the company's continuing Murphy Lake uranium drill program in Saskatchewan;
• Company optioned the Jean Lake property in July, 2021, and earned a 100-per-cent interest announced on July 16, 2025;
• Located in proven gold jurisdiction in Snow Lake, Man., which includes Hudbay Minerals' core operating area, which has produced more than one million ounces of gold at its Lalor mine (1);
• Previous drilling includes high-grade gold and lithium intercepts, including 7.50 g/t Au over 7.66 metres (including 102.0 g/t Au over 0.48 metre) in drill hole FM23-8 and 1.26 per cent Li2O over 3.35 metres in drill hole FM23-04A.

Foremost's 2022-2023 drill campaign

The company completed a 3,002-metre initial diamond drill program, designed to drill test targets based on integrated prospecting, UAV-borne (unmanned aerial vehicle) magnetic survey results, MMI (mobile metal ion) soil geochemical surveys and outcrop rock chip analyses (see news release dated June 6, 2023). The program intersected numerous gold mineralized intervals at vertical depths up to 110 metres below surface, as well lithium at the B1 spodumene-bearing pegmatite. Details of the lithium and gold intersections are provided in the attached table.

Highlights include the following.

Gold:

• In drill hole FM23-8: 7.50 g/t Au over 7.66 metres from 94.35 to 102.01 metres (including 102.0 g/t Au over 0.48 metre from 94.77 to 95.25 metres);
• In drill hole FM23-04A: 11.27 g/t Au over 2.75 metres from 73.75 to 76.50 metres (including 91.8 g/t Au over 0.32 metre from 74.74 to 75.06 metres);
• In drill hole FM23-01A: 2.46 g/t Au over 3.70 metres from 41.30 to 45.00 metres.

Lithium:

• 1.26 per cent Li2O over 3.35 metres from surface in drill hole FM23-01A.

Foremost's 2025 Jean Lake diamond drill program

The company anticipates the drill program to commence before the end of September, 2025, with the goal to expand both the lithium and gold mineralized systems. Drill target locations are currently being finalized by Foremost's technical team.

About Foremost Clean Energy Ltd.

Foremost is a rapidly growing North American uranium and lithium exploration company. The company holds an option to earn up to a 70-per-cent interest in 10 prospective uranium properties (with the exception of the Hatchet Lake, where Foremost is able to earn up to 51 per cent), spanning over 330,000 acres in the prolific, uranium-rich Athabasca basin region of Northern Saskatchewan. As the demand for carbon-free energy continues to accelerate, domestically mined uranium and lithium are poised for dynamic growth, playing an important role in the future of clean energy. Foremost's uranium projects are at different stages of exploration, from grassroots to those with significant historical exploration and drill-ready targets. The company's mission is to make significant discoveries alongside and in collaboration with Denison through systematic and disciplined exploration programs.

Foremost also has a portfolio of lithium projects at varying stages of development, which are located across 55,000-plus acres in Manitoba and Quebec.
