Foremost Clean Energy Reports Final Results of 2025 Jean Lake Drill Program Including High Grade Gold Intercepts

Executive Summary

• Foremost Clean Energy reports high‑grade near‑surface gold intercepts from its 15‑hole, 2,266 m 2025 drill program, expanding the known mineralized corridor to ~600 m of strike along the Valkyrie Trend.
• Notable intercepts include 9.4 g/t Au over 2.2 m (incl. 27.9 g/t Au over 0.7 m) in hole JL25‑010 and 6.2 g/t Au over 2.6 m (incl. 31.1 g/t Au over 0.5 m) in hole JL25‑009, confirming robust, shallow‑depth shear‑zone gold mineralization.
• Company plans step‑out and infill drilling to further extend the corridor and target higher‑grade zones, indicating continued exploration upside.

Key Details

• Program Overview: 15 drill holes, total depth 2,266 m (see prior release Dec 8 2025).
• Significant Intercepts
• JL25‑010: 9.4 g/t Au over 2.2 m from 48.0 m (incl. 27.9 g/t Au over 0.7 m).
• JL25‑009: 6.2 g/t Au over 2.6 m from 52.5 m (incl. 31.1 g/t Au over 0.5 m); also 1.5 g/t Au over 9.1 m (incl. 9.1 g/t Au over 0.9 m) and 1.6 g/t Au over 6.7 m (incl. 9.2 g/t Au over 1.0 m).
• JL25‑006: 2.9 g/t Au over 6.7 m from 169.5 m (incl. 32.6 g/t Au over 0.5 m); plus 2.6 g/t Au over 2.5 m from 36.0 m (incl. 6.2 g/t Au over 0.5 m).
• JL25‑007: 2.6 g/t Au over 5.4 m from 43.4 m (incl. 6.8 g/t Au over 1.8 m).
• Strike Length: Gold mineralization now intersected across ~600 m of strike along the Valkyrie Trend, a substantial increase in system scale.
• Geology: Intercepts hosted in a steeply dipping shear zone with quartz veining and sericite alteration; broad 5‑7 m envelopes of 1–3 g/t Au containing higher‑grade zones (20‑80 g/t Au).
• Historical Context: Discovery hole JL23‑008 (2023) returned 7.5 g/t Au over 7.66 m (incl. 102 g/t Au over 0.48 m); earlier 2025 holes (JL25‑001 to JL25‑004) reported up to 12.7 g/t Au over 2.07 m.
• Next Steps: Planned step‑out and infill drilling to test strike extensions, target higher‑grade zones, and refine structural controls.
• QA/QC: Core sampled at 0.5–1.5 m intervals; analyses performed by SGS Canada using fire assay (30 g) with AAS finish; QA/QC insertion of blanks, standards, duplicates (~11‑12% of samples).
• Qualified Person: Cameron MacKay, P.Geo., VP Exploration, reviewed technical content per NI 43‑101.

Notable Quotes

“These final results complete a successful 2025 drill campaign and significantly advance our understanding of the Jean Lake property… Our 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.” – Jason Barnard, President & CEO

Materiality Assessment: Material – Positive (the results materially enhance the company's gold resource potential and support continued exploration investment).
