Foremost Clean Energy Reports Significant Increase in Uranium Grade from Assays Received for Recent Discovery at its Hatchet Lake Project
Executive Summary
- Final geochemical assay results from the 2025 winter drill program at Hatchet Lake Uranium Property significantly upgraded the grade of the flagship hole TF‑25‑16, now reporting 0.87 % U₃O₈ over 0.45 m (previously 0.22 %).
- A total of 6.2 m of mineralization at 0.10 % U₃O₈ was intersected in TF‑25‑16, confirming a high‑grade core within the Tuning Fork target and suggesting proximity to a larger unconformity‑related system.
- Additional drill holes (TF‑25‑13, TF‑25‑14, TF‑25‑15, TF‑25‑17/18/20) identified extensive hydrothermal alteration and pathfinder element anomalies, supporting the potential for expanded mineralized zones.
Key Details
- Hole TF‑25‑16 (Tuning Fork target)

- Sub‑interval 149.75–150.2 m (0.45 m): 0.87 % U₃O₈ (previously estimated 0.22 %).
-
Sub‑interval 144.5–145.0 m (0.5 m): 0.20 % U₃O₈.
-
Hole TF‑25‑13 – 2.5 m of 0.03 % U₃O₈ from 115.0 m at the Athabasca unconformity.
- Hole TF‑25‑14 – Pathfinder anomalies: 1.0 m of 221 ppm Cr, 533 ppm Cu, 399 ppm Ni from 125.23 m.
-
Hole TF‑25‑15 – 0.5 m of 167 ppm Cr at 134.1 m.
-
Follow‑up holes (TF‑25‑17, TF‑25‑18, TF‑25‑20) intersected strong hydrothermal alteration above and below the mineralized interval, extending alteration ≥50 m strike‑wise to the NE.
-
Richardson target – Hole RL‑25‑32

Interval 240.2–240.4 m (0.2 m): 0.05 % U₃O₈.
-
Hole RL‑25‑31 – 2.93 m of 5,215 ppm Boron (key pathfinder for unconformity‑related uranium).
-
Exploration next steps:
- Integration of new geochemical, structural, and clay mineralogy data to refine vector targeting.
- VTEM conductor modelling underway to better define strike/dip of the Tuning Fork conductor.
- Planned winter 2025‑2026 ground gravity survey over SE extension of Richardson trend.
-
Development of a 2026 winter drill program to follow up on 2025 results.
-
Analytical methodology: Core shipped to Saskatchewan Research Council labs; assays performed by ICP‑MS/OES with HF:HNO₃:HClO₄ digestion for total analysis and HNO₃:HCl partial digests; U₃O₈ measured by ICP‑OES against high‑grade standards.

Notable Quotes
“This discovery at the Tuning Fork target on the Hatchet Lake Property is an incredibly exciting milestone for our Company… The assay results have upgraded our expectations for this area, with a 6.2 metre zone of mineralization that is now headlined by a 0.45 metre interval of nearly 1 % U₃O₈.” – Jason Barnard, President & CEO
Materiality Assessment: Material – Positive** (the upgraded grades and expanded mineralized intervals represent a significant positive development for the company’s uranium exploration program).
