Foremost Clean Energy Intersects High-Grade Uranium Mineralization at Hatchet Lake South Project
VANCOUVER, British Columbia – Foremost Clean Energy Ltd. has announced promising results from its 2026 drill program at the Hatchet Lake South Uranium Project, located in the eastern Athabasca Basin region of northern Saskatchewan. The company reported intersecting unconformity-related uranium mineralization in five drillholes, with highlights including 0.34% eU₃O₈ over 4.6 meters, featuring a high-grade interval of 1.0% eU₃O₈ over 1.4 meters.
Expanding Mineralization Footprint
Three drill fences stepping out from the 2025 discovery hole TF-25-16 have expanded the mineralized footprint to over 150 meters of strike length. This area is now designated as the Tuning Fork Uranium Zone, characterized by continuous uranium mineralization and hydrothermal alteration along brittle reactivated structures at the Athabasca unconformity.
Jason Barnard, President and CEO of Foremost Clean Energy, commented on the findings: "These preliminary results from our 2026 drill program at Hatchet Lake continue to build on the 2025 Tuning Fork discovery and on the strong geological foundation established by previous drilling completed by our largest shareholder and strategic ally, Denison Mines Corp."
Barnard added, "Step-out drilling from drill hole TF-25-16 has now intersected uranium mineralization across three drill fences, expanding the mineralized footprint to over 150 metres of strike length, demonstrating the growing scale of the system."
Key Drill Results
The company provided specific highlights from the drilling program:
- 0.34% eU3O8 over 4.6m from 138.1m (includes 1.0% eU3O8 over 1.4m) in drill hole TF-26-30
- 0.06% eU3O8 over 6.9m from 134.0m in drill hole TF-26-24
- 0.13% eU3O8 over 0.7m from 140.0m in drill hole TF-26-27A
To date, a total of ten diamond drill holes (2,113 meters) have been completed as part of the ongoing 2026 drill program at the Tuning Fork Uranium Zone. Five of these holes intersected unconformity-related uranium mineralization meeting or exceeding the company's reporting threshold of 0.05% eU₃O₈.
Geological Significance
Uranium mineralization was intersected across three drill fences stepping out from the discovery hole TF-25-16, confirming continuity of the system along strike. All completed drill holes encountered anomalous radioactivity (greater than 2x background) and hydrothermal alteration at the Athabasca unconformity, expressed in both the overlying sandstone and underlying basement rocks.
"The consistent presence of uranium mineralization and hydrothermal alteration at the unconformity across all drill fences is also highly encouraging," Barnard noted. "We are well positioned to keep expanding this area through continued drilling. We look forward to further advancing this exciting Tuning Fork Uranium Zone as we work to define its full scale and significance within the Hatchet Lake Project."
The current interpreted footprint of uranium mineralization and associated hydrothermal alteration at the Tuning Fork Uranium Zone now extends over 150 meters of strike length, with drill collar locations for the 2026 program documented in company records.
