FOREMOST CLEAN ENERGY COMMENCES 2025 DRILLING PROGRAM AT HATCHET URANIUM PROJECT

Foremost Clean Energy Ltd. has begun its 2025 exploration drill program at the Hatchet Lake uranium project, located in the world-renowned Athabasca basin of Northern Saskatchewan. The 2,000-metre, helicopter-supported diamond drill program commenced recently and is being conducted on behalf of Foremost by Dahrouge Geological Consulting Ltd. (DGC). Drill testing during this program is expected to evaluate the project's top exploration prospects at both the Tuning Fork target area and the Richardson target area.

"We are excited to commence this fully funded drill program at Hatchet," said Jason Barnard, Foremost's president and chief executive officer. "This program represents a significant step forward for Foremost, launching our first exploration drill program in the Athabasca basin, designed to evaluate several discovery-ready target areas on a well-situated and advanced exploration project that is part of our unique collaboration with Denison Mines Corp. Our drill targets for this program have been designed to test interpreted structures and conductive breaks identified based on the wealth of historic exploration already completed on this exciting property."

Hatchet is located within 1.5 kilometres of the Athabasca basin margin, which results in shallow sandstone cover (fewer than 220 metres) and corresponding shallow exploration targets, enabling efficient and cost-effective drill testing. The 2025 drill campaign plans to capitalize on this advantage, including multiple drill holes to advance the evaluation of several target areas -- each of which is highly prospective and has the potential for discovery, or which will benefit in future drill programs from additional reconnaissance.

Tuning Fork

The shallow drill targets at Tuning Fork comprise 1,000 m of the planned drilling with an unconformity depth ranging from 120 m to 160 m. Historical drilling and the 2024 drill program have identified prominent structures and alteration along conductive trends identified via ground electromagnetic (EM) surveys that are coincident with previously identified mineralization located near structures at the unconformity. A folded conductive package of graphitic metasediments adjacent to the structure underscores the key elements for uranium mineralization.

Richardson

The balance of drilling at Hatchet during this program (approximately 1,000 m) is planned to consist of follow-up drilling and reconnaissance drilling at the Richardson target area. A series of discrete linear EM conductive anomalies (approximately seven km in total length) comprise the Richardson target area. Historical drilling has confirmed the presence of mineralization along the conductive trend at and immediately below the unconformity. Follow-up drilling is designed to test the continuity of mineralization along strike and obtain structural data on mineralized structures identified in historical holes. Additional drilling is expected to test certain prospective, unexplored conductive trends to evaluate the potential to host uranium mineralization.

About Foremost Clean Energy Ltd.

Foremost Clean Energy is an emerging North American uranium and lithium exploration company with an option to earn up to a 70-per-cent interest in 10 prospective uranium properties (with the exception of 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 clean-energy mix of the future. 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 greater than 55,000 acres in Manitoba and Quebec.
