VANCOUVER, British Columbia — February 25, 2026 — Leads & Copy — Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) has reported final assay results from its 2025 diamond drill program at its 100%-owned Jean Lake Gold-Lithium Property near Snow Lake in Manitoba.
The program included 15 drill holes totaling 2,266 meters. Final assays revealed high-grade, near-surface intercepts, including 9.4 g/t Au over 2.2 meters from 48.0 meters (including 27.9 g/t Au over 0.7 meters) in JL25-010 and 6.2 g/t Au over 2.6 meters from 52.5 meters (including 31.1 g/t Au over 0.5 meters) in JL25-009.
These results continue to define and expand the near-surface gold system along the Valkyrie Trend. Gold mineralization has now been intersected along approximately 600 meters of strike length on and adjacent to the Valkyrie Trend, increasing the scale of the emerging gold system.
Highlights from the drilling program include:
JL25-006:
- 2.9 g/t Au over 6.7 m starting at 169.5 m, including 32.6 g/t Au over 0.5 m
- 2.6 g/t Au over 2.5 m starting at 36.0 m, including 6.2 g/t Au over 0.5 m
JL25-007:
- 2.6 g/t Au over 5.4 m starting at 43.4 m, including 6.8 g/t Au over 1.8 m
JL25-009:
- 6.2 g/t Au over 2.6 m starting at 52.5 m, including 31.1 g/t Au over 0.5 m
- 1.5 g/t Au over 9.1 m starting at 15.4 m, including 9.1 g/t Au over 0.9 m
- 1.6 g/t Au over 6.7 m starting at 30.0 m, including 9.2 g/t Au over 1.0 m
JL25-010:
- 9.4 g/t Au over 2.2 m starting at 48.0 m, including 27.9 g/t Au over 0.7 m
According to Jason Barnard, Foremost’s President and CEO, the final results complete a successful 2025 drill campaign and significantly advance the understanding of the Jean Lake property. Barnard said that what began as a high-grade discovery in 2023 has now evolved into a ~600-meter mineralized gold corridor along the Valkyrie Gold Trend, characterized by consistent higher-grade zones within broader mineralized envelopes. Mineralization occurs at shallow depths in several holes and remains open along strike and at depth, reinforcing the company’s confidence that this represents a robust shear zone gold system rather than isolated occurrences.
The next phase will focus on step-out and infill drilling to expand the corridor and further define and target the higher-grade components of this structurally controlled system, Barnard said.
Gold mineralization at Jean Lake was first identified in discovery hole JL23-008 in 2023, which returned 7.5 g/t Au over 7.66 meters including 102.0 g/t Au over 0.48 meters. Drill holes JL25-001 through JL25-004 expanded the mineralized footprint and confirmed continuity along the Valkyrie Trend, including:
- JL25-001: 12.7 g/t Au over 2.07 m (including 40 g/t Au over 0.6 m)
- JL25-002: 10.7 g/t Au over 5.6 m (including 82 g/t Au over 0.7 m)
- JL25-003: 9.0 g/t Au over 3.5 m (including 34.2 g/t Au over 0.8 m)
The results from holes JL25-006 through JL25-015 further extend and define gold mineralization along the Valkyrie Trend. Gold mineralization has now been identified over approximately 600 meters of strike length. Gold mineralization is interpreted to be primarily hosted within a steeply dipping shear zone characterized by quartz veining and sericite alteration. Mineralized intercepts are characterized by broad (~5-7m) 1–3 g/t Au mineralized envelopes hosting higher-grade zones exceeding 20–80 g/t Au. Multiple drill fences between 2023 and 2025 on and adjacent to the Valkyrie Trend illustrate a robust gold system that remains open along strike and at depth.
Following the identification of mineralization across roughly 600 metres of strike length along the Valkyrie Trend, the Company intends to advance a focused follow-up program. This program will include step-out and infill drilling to test strike extensions beyond the currently defined limits and to target higher-grade zones within the broader mineralized corridor. Work will also continue to evaluate structural controls and lithological influences on gold distribution in order to refine drill targeting and guide the next phase of exploration.
