Exploring the Tuning Fork Uranium Zone: Updates from Foremost Clean Energy's 2026 Drill Program
Foremost Clean Energy Ltd. is excited to share updates from its ongoing 2026 drill program at the Hatchet Lake South Uranium Project in northern Saskatchewan. The drilling has revealed significant uranium mineralization in five drillholes, with notable results including 0.34% eU₃O₈ over 4.6 meters, including a high-grade interval of 1.0% eU₃O₈ over 1.4 meters. The discovery has expanded the mineralized footprint to over 150 meters of strike length, now known as the "Tuning Fork Uranium Zone," characterized by continuous uranium mineralization and hydrothermal alteration along brittle reactivated structures at the Athabasca unconformity.
The President and CEO of Foremost, Jason Barnard, expressed enthusiasm about the preliminary results from the 2026 drill program, building on the 2025 Tuning Fork discovery. The company plans to continue expanding the area through further drilling to define the full scale and significance of the Tuning Fork Uranium Zone within the Hatchet Lake Project.
The ongoing 2026 drill program at the Tuning Fork Uranium Zone has seen ten diamond drill holes completed, with five intersecting uranium mineralization meeting or exceeding the reporting threshold. The mineralization has been confirmed along strike from the discovery hole TF-25-16, with all completed drill holes encountering anomalous radioactivity and hydrothermal alteration at the Athabasca unconformity. The current footprint of uranium mineralization and associated hydrothermal alteration extends over 150 meters of strike length.
As drilling continues, Foremost's focus will be on expanding the Tuning Fork Uranium Zone, which remains open along strike to the north. The company plans to test for further extensions of uranium mineralization and define the geometry and controls of the system to target higher-grade zones. Additionally, Foremost intends to advance other high-priority targets across the Hatchet Lake Project, including the Tuning Fork West and Tuning Fork East target areas, the Beta Grid at Hatchet Lake South, and the Richardson SE target area at Hatchet Lake North.
The Company employs a data-driven exploration strategy supported by extensive historic drilling and geophysical data across its portfolio, including programs completed by Denison Mines Corp. The combination of continued success at the Tuning Fork Uranium Zone and a strong pipeline of untested, drill-ready targets positions Hatchet Lake as a highly prospective project for further uranium discoveries.
