Foremost Clean drills 0.8 m of 34.2 g/t Au at Jean Lake

Executive Summary

• Foremost Clean Energy Ltd. reports assay results from drill holes JL25-003 and JL25-004 at its 100%-owned Jean Lake gold-lithium property in Manitoba, confirming a shallow, high-grade gold system along the Valkyrie trend.
• Significant intercepts include a high-grade interval of 34.2 g/t Au over 0.8 m within 9.0 g/t Au over 3.5 m in hole JL25-003, with all reported mineralization occurring within 100 meters of surface.
• The results validate the 2025 exploration model, demonstrating consistent near-surface mineralization and expanding the footprint of the discovery made in 2023, with further drilling planned to test stepouts and lithium-bearing pegmatite targets.

Key Details

• Drill Hole JL25-003:
  • 34.2 g/t Au over 0.8 m included within 9.0 g/t Au over 3.5 m starting at 127.8 m.
  • 9.7 g/t Au over 0.5 m included within 2.7 g/t Au over 2.6 m starting at 89.1 m.
  • 6.2 g/t Au over 1.0 m included within 1.81 g/t Au over 7.0 m starting at 104.5 m.
• Drill Hole JL25-004:
  • 6.6 g/t Au over 0.7 m within 2.7 g/t Au over 1.6 m starting at 101.7 m.
  • 5.4 g/t Au over 0.5 m within 3.2 g/t Au over 1.5 m starting at 90.0 m.
  • 3.3 g/t Au over 0.5 m included within 1.3 g/t Au over 1.5 m starting at 87.0 m.
• Historical Context & Continuity:
  • Previous hole JL25-001 returned 40 g/t Au over 0.6 m within 12.7 g/t Au over 2.07 m.
  • Previous hole JL25-002 returned 82 g/t Au over 0.7 m within 10.7 g/t Au over 5.6 m.
  • Historical hole FM23-08 returned 102 g/t Au over 0.48 m within 7.50 g/t Au over 7.66 m.
  • All these intercepts occur within 100 meters of surface.
• Project Status:
  • The 2025 drill program aims to test the scale and continuity of the gold discovery and delineate the near-surface, spodumene-bearing B1 pegmatite.
  • Next steps include further stepouts along the Valkyrie trend and initial testing of lithium-bearing pegmatite targets.
• Technical Methodology:
  • Samples collected as NQ-sized core; sampled at 50cm intervals in veined zones and 1.5m intervals outside.
  • Analysis performed by SGS Canada Inc. using 30g fire assay with atomic absorption spectrometry finish (detection 5-10,000 ppb) and gravimetric finish for high grades.
  • Qualified Person: Cameron MacKay, PGeo, VP of Exploration.

Notable Quotes

• "We are increasingly encouraged by what we are seeing at Jean Lake. Each stage of drilling... continues to confirm a shallow, high-grade gold system along the Valkyrie trend." — Jason Barnard, President and CEO.
• "What really sets these results apart is the consistently shallow depths. Discovering this calibre of gold mineralization less than 100 metres from surface is highly advantageous for ongoing exploration..." — Jason Barnard, President and CEO.
• "With gold markets remaining exceptionally strong, we believe Jean Lake is emerging at exactly the right moment. The combination of shallow high-grade results and a supportive macro environment positions the project as a compelling value driver for our shareholders." — Jason Barnard, President and CEO.
