Foremost Clean Energy Announces Upcoming Ground-Based Gravity Survey at its Hatchet Lake Uranium Project, Athabasca Basin, Saskatchewan

Executive Summary

• Foremost Clean Energy will commence a ground‑based gravity survey over its Hatchet Lake Uranium Property in December 2025, covering ~788 stations to refine the geological model along the Richardson Trend.
• The survey results are intended to guide a winter‑2026 drill program targeting priority structural corridors on the southeast extension of the Richardson Trend and the Tuning Fork Target Area.
• Historic drilling by Denison Mines on the trend returned notable uranium intercepts (1.52% U₃O₈ over 0.15 m; 0.45% U₃O₈ over 2.3 m), underscoring the area’s prospective potential.

Key Details

• Survey Scope: ~788 gravity stations, 100‑m station spacing on 200‑m line spacing across priority structural corridors of the southeast Richardson Trend extension.
• Contractor: MWH Geo Survey (MWH), a geophysical contractor with >40 years experience in the Athabasca Basin.
• Objective: Identify gravity lows and gradients linked to hydrothermal alteration halos, fault‑controlled fluid pathways, and graphitic shear zones; integrate results with existing EM, magnetic, and geochemical data.
• Target Prioritization: Anomalies overlapping gravity lows, magnetic structures, and geochemical signatures will be earmarked for drill testing.
• Planned Drill Program: Anticipated start early 2026, focusing on:
• Priority targets along the Richardson Trend’s southeast extension (≈6 km of under‑tested conductor strike length).
• Tuning Fork Target Area.
• Historical Drilling Highlights (Denison Mines):
• Hole RL‑13‑131 – 1.52% U₃O₈ over 0.15 m.
• Hole RL‑13‑161 – 0.45% U₃O₈ over 2.3 m.
• Qualified Person Review: Technical content approved by Cameron MacKay, P.Geo., VP Exploration (NI 43‑101 Qualified Person).
• Forward‑Looking Statements: Survey and drill plans are subject to risks including capital availability, permitting, and execution of the option agreement with Denison Mines.

Notable Quotes

“The Hatchet Lake gravity survey marks an important step in refining our geological model along the Richardson Trend… 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.” – Jason Barnard, President & CEO

Materiality Assessment: Non‑Material – Positive (operational update without immediate financial impact but indicative of continued exploration advancement).
