Foremost to begin gravity survey over Hatchet Lake

Executive Summary

• Foremost Clean Energy Ltd. announced the commencement of a ground-based gravity survey in December at its Hatchet Lake uranium project in the Athabasca Basin, Saskatchewan.
• The survey aims to refine the geological model along the Richardson trend, specifically targeting the southern extent where drilling has been limited, to identify structural targets for a planned winter 2026 drill program.
• The company highlighted the prospective nature of the southeastern extension of the Richardson trend, citing historic drilling results from Denison Mines Corp. and analogies to major uranium systems like ISO Energy's Hurricane deposit.

Key Details

• Survey Scope: Ground-based gravity survey to be conducted by MWH Geo Survey.
• Technical Parameters: Approximately 788 gravity stations collected at 100-metre station intervals on 200-metre line spacing.
• Target Area: Southeast extension of the Richardson trend, extending beyond the Athabasca basin margin.
• Objective: Map density contrasts, identify potential zones of hydrothermal alteration, and prioritize gravity anomalies overlapping with graphitic shear zones and magnetic structures for future drill testing.
• Future Drilling: Anticipated drill program scheduled to commence in early 2026, focusing on the Richardson trend and the Tuning Fork target area.
• Historic Context: Reference to historic drilling by Denison Mines Corp. on the Richardson trend, including:
  • Hole RL-13-131: 1.52% U3O8 over 0.15m.
  • Hole RL-13-16: 0.45% U3O8 over 2.3m.
• Geological Analogy: The area is described as analogous to the La Rocque corridor, hosting ISO Energy's Hurricane deposit and Cameco's La Rocque Lake uranium zone.
• Qualified Person: Cameron MacKay, PGeo, VP of Exploration, reviewed and approved the technical content.

Notable Quotes

• Jason Barnard, President and CEO: "The Hatchet Lake gravity survey marks an important step in refining our geological model along the Richardson trend. By integrating gravity, electromagnetic, magnetic and geochemical data, we are building a more complete picture of the subsurface architecture that controls uranium mineralization in this area. The results are expected to directly influence our winter 2026 drill program, ensuring that our next round of drilling is focused, data-driven and aligned with the most prospective structural targets."
