Foremost Clean Energy Announces Successful Completion of 2025 Drill Program and Commencement of Historic Core Sampling Program at its Jean Lake Gold-Lithium Project

VANCOUVER, British Columbia, Dec. 08, 2025 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ:FMST) (CSE:FAT) ("Foremost" or the "Company"), is pleased to announce the successful completion of its 2025 diamond drill program at the 100%-owned Jean Lake Gold–Lithium Property ("Jean Lake") located near Snow Lake, Manitoba. The program comprised 15 holes totaling 2,266 metres, with assay results from four holes already reported and results from the remaining 11 holes currently pending. Concurrently, the Company announces the commencement of a strategic core re-sampling program that will focus on high-priority drill core from its previous completed 2023 drill program. The focus of this program is to obtain a more comprehensive dataset to enhance the geological model due to the potential of improved results and expand the understanding of known mineralization.

Jason Barnard, Foremost's President and CEO, commented: "The completion of our 2025 drill program successfully adds another 2,266 metres of data to the Jean Lake story. While we await these new assays, we are taking the proactive step of re-sampling high-priority 2023 core from intervals adjacent to known high-grade intercepts, like the 102 g/t gold in FM23-08. This cost-effective program is designed to fill in geological gaps and has the potential to positively impact our understanding of the mineralized system's scale and continuity. Integrating this new data with all past and pending results will allow us to build the most robust geological model possible as we plan for future drilling."

Post-Program Sampling Underway

To support ongoing geological interpretation, a dedicated sampling crew has remained on site. Re-sampling will focus on unsampled intervals that may further clarify gold continuity and grade distribution along the Valkyrie Trend. A total of six high-priority 2023 drillholes along the Valkyrie Trend have been selected for re-sampling in 2025 (Figure 1). These include hole FM23-08, which previously returned 102 g/t Au over 0.5 m, within 7.50 g/t Au over 7.66 m. (See news release June 06, 2023). In addition, one drillhole from the Midas Trend, FM23-25, is being re-sampled (Figure 1). Historical highlights from FM23-25 include 6.86 g/t Au over 0.54 m, within 2.07 g/t Au over 3.49 m. (See news release (June 06, 2023).

2025 Drill Program and Next Steps

The Company's 2025 diamond drill program, comprising 15 holes (JL25-001 to JL25-015), was designed to follow up on the 2023 drill program, to expand the Company's understanding of the emerging near-surface gold system along the Valkyrie Trend and test the spodumene-bearing B1 Pegmatite. Assay results for holes JL25-005 to JL25-015 are pending.

Upon receipt of all outstanding assays and the new re-sampling data, Foremost will begin a comprehensive update of its geologic and structural model for Jean Lake. This integrated model will combine the 2023 discovery holes, all 2025 assay results, and the new re-sampling data from the 2023 holes.   This work will refine priority targets along both the Valkyrie and Midas Trends where mineralization remains untested. The updated model will guide the design for drill targets of an expanded drill program anticipated for 2026.

About Foremost

Foremost Clean Energy Ltd. (NASDAQ:FMST) (CSE:FAT) (WKN: A3DCC8) is a rapidly growing North American uranium and lithium exploration company. . The Company holds an option from Denison Mines Corp. ("Denison") to earn up to 70% interest in 10 prospective uranium properties (except for the Hatchet Lake, where Foremost can earn up to 51%), 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+ acres in Manitoba and Quebec. For further information, please visit the Company's website at www.foremostcleanenergy.com.
