Foremost Clean Energy Commences 2026 Winter Diamond Drill Program at Hatchet Lake Uranium Project

Executive Summary

• Foremost Clean Energy Ltd. has begun its ~5,000‑metre winter diamond drill program at the Hatchet Lake Uranium Project in Saskatchewan.
• Initial drilling targets the Tuning Fork area, following a 2025 discovery (TF-25-16) that intersected 0.87% U₃O₈ over 0.45 m within a broader 6.2‑m interval averaging 0.10% U₃O₈ at the Athabasca unconformity.
• The program will test along‑strike and down‑dip continuity, refine structural controls, and evaluate additional high‑priority targets across Hatchet Lake South and North.

Key Details

• Program Scope: Approximately 5,000 metres of diamond drilling planned for the winter season.
• Initial Target – Tuning Fork (Hatchet Lake South):
• Follows 2025 discovery hole TF‑25‑16 (0.87% U₃O₈ over 0.45 m; 6.2 m @ 0.10% U₃O₈).
• Objectives: test continuity of mineralization, refine structural controls at the Athabasca unconformity, and evaluate a newly identified EM conductor west of the discovery.
• Additional Targets (contingent on Tuning Fork progress):
• Beta Grid (Hatchet Lake South): Structurally controlled target linked to displacement of the Athabasca unconformity and a conductive corridor.
• Richardson SE (Hatchet Lake North): >5 km of untested EM conductor strike length; ground gravity data being integrated to focus on structural complexity and hydrothermal alteration zones.
• Target Selection Methodology: Utilized Denison Mines’ historical drilling and geophysical datasets, refined with Foremost’s updated interpretation and conductor modelling to tighten target geometry.
• Qualified Person Review: Technical content approved by Cameron MacKay, P.Geo., Vice President of Exploration (NI 43‑101 Qualified Person).
• Forward‑Looking Statements: The release contains forward‑looking statements regarding the program’s objectives, expected results, and future drilling plans; risks and uncertainties are disclosed in the standard disclaimer.
