Foremost Clean Energy Reports Results of its Historic Core Sampling Program at its Jean Lake Property

Executive Summary

• Foremost Clean Energy released historic core resampling results from its 100% owned Jean Lake Gold‑Lithium Property, confirming additional gold mineralization in previously unsampled intervals.
• Notable intercepts include 1.10 g/t Au over 8.0 m (22.0–30.0 m) with a higher‑grade sub‑interval of 6.9 g/t Au over 0.5 m, and 0.64 g/t Au over 10 m (106.5–116.9 m).
• The new data extend the known mineralized envelope along the Valkyrie Trend to ~600 m strike length and will guide step‑out and infill drilling in the next exploration phase.

Key Details

• Program Scope: Targeted resampling of unsampled sections from 2023 drillholes (Valkyrie & Midas Gold Trends) following the Dec 2025 diamond drill campaign.
• Key Intercepts – Resample Results
• Hole FM23‑25: 1.10 g/t Au over 8.0 m (22.0–30.0 m); includes 6.9 g/t Au over 0.5 m.
• Hole FM23‑08: 0.64 g/t Au over 10.4 m (106.5–116.9 m).
• Additional Significant Intercepts (Table 1 Highlights)
• FM23‑04A: 0.53 g/t Au over 1.0 m (36.0–37.0 m) – gap‑fill.
• FM23‑04A: 11.30 g/t Au over 2.7 m (73.8–76.5 m) – original 2023 assay.
• FM23‑05: Multiple low‑grade intervals; notable 3.05 g/t Au over 0.3 m (86.2–86.5 m).
• FM23‑08: Weighted‑average 7.85 g/t Au over 7.3 m (94.4–101.6 m) – original 2023 data.
• Interpretation Impact:
• Confirms mineralization extends beyond previously reported intercepts and fills sampling gaps, improving continuity of the geological model.
• Updated model will prioritize higher‑grade zones within broader low‑grade envelopes for upcoming step‑out and infill drilling.
• Next Steps:
• Integrate resample data with 2025 drill results (announced Feb 25 2026).
• Refine structural and geological models; define mineralized envelopes along ~600 m strike length.
• Plan follow‑up drilling to test continuity at depth and laterally.
• QA/QC: Core sampled NQ size, intervals of 0.5–1.5 m; analysis performed by SGS Canada using fire assay (30 g) with AAS finish; QA/QC inserts blanks, standards, duplicates (~11‑12% of samples).
• Qualified Person: Cameron MacKay, P.Geo., VP Exploration, reviewed and approved technical content under NI 43‑101.

Notable Quotes

“This targeted resampling program was designed to address previously unsampled intervals within mineralized sections and improve the representation of gold distribution… These results support refinement of the geological interpretation and will inform step‑out and infill drill targeting in the next phase of exploration at Jean Lake.” – Jason Barnard, President
