FOREMOST CLEAN ENERGY ANNOUNCES 3-YEAR DRILL PERMIT FOR HATCHET URANIUM PROJECT AND PLANS FOR UPCOMING 3,000 METRE WINTER DRILL PROGRAM

Foremost Clean Energy Ltd. has received a three-year exploration permit from the Saskatchewan Ministry of Environment for its Hatchet Lake uranium project, located in the world-renowned Athabasca basin region of Northern Saskatchewan. The permit is valid until Dec. 28, 2028, and authorizes up to 50 drill holes. A phase 2, 3,000-metre drill program is being planned for winter 2025 to 2026. Phase 2 will focus on following up the Tuning Fork discovery (see news release May 15, 2025), and testing high-priority targets that were initially identified and advanced through historic work by Denison Mines Corp.

"Securing this three-year permit is an important milestone, as it provides Foremost with significant runway to explore this highly prospective property and rapidly follow-up positive results," states Jason Barnard, president and chief executive officer of Foremost. "The uranium industry is at a historic inflection point. The recent World Nuclear Association symposium highlighted an 'absolute undeniable' supply-demand deficit, with projections of 700 GW of SMR capacity by 2050 adding to the already urgent need for new uranium discoveries. At the same time, the $100-billion OpenAI-Nvidia deal illustrates the potential for exponential energy demand from the digital economy, where access to clean, reliable power is becoming the ultimate bottleneck. Together, these forces make clear that nuclear energy is the only scalable solution-and investment in uranium exploration now is necessary to meet the projected demands of a growing fleet of nuclear power plants. We believe our aggressive exploration strategies at Hatchet Lake, alongside our ongoing program at Murphy Lake South, positions Foremost at the forefront of this essential search for new source fuel supply. We are committed to potentially deliver the discoveries needed to power the future clean energy economy and generate shareholder value."

Winter 2025 to 2026 drill program: high-priority uranium targets

The company plans to initiate a 3,000-metre drill program this winter, which is expected to test multiple target areas on the property, with the following objectives.

• Expand the New Tuning Fork discovery where drill hole TF-25-16, which intersected 0.10 per cent eU3O8 (radiometric equivalent triuranium octoxide) over 6.5 metres, including 0.22 per cent eU3O8 over 0.9 m (assays pending);
• Drill test high-priority targets on the Richardson trend that were initially identified and advanced through historic work by Denison;
• Drill test the Beta Grid where historic drilling indicated a 35 m unconformity offset.

Foremost is committed to disciplined, high-impact exploration aimed at unlocking the next generation of unconformity-related uranium deposits in the Athabasca basin. By advancing these targets in parallel with its broader project portfolio, Foremost believes that it is well situated to deliver discovery-driven growth and long-term value creation for its shareholders.

About Foremost Clean Energy Ltd.

Foremost Clean Energy is a rapidly growing North American uranium and lithium exploration company. The company holds an option from Denison Mines Corp. to earn up to 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.
