Foremost Clean Energy Intersects High-Grade Unconformity Mineralization at Hatchet Lake South Project with 1.4m of 1.0% eU3O8 within 4.6m of 0.34% eU3O8

VANCOUVER, British Columbia, April 15, 2026 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost” or the “Company”) is pleased to provide an update from its ongoing 2026 drill program at the Hatchet Lake South Uranium Project (“Hatchet Lake”), located in the eastern Athabasca Basin region of northern Saskatchewan (Figure 1). Drilling has intersected unconformity-related uranium mineralization in five drillholes, highlighted by 0.34% eU₃O₈ over 4.6 metres, including a high-grade interval of 1.0% eU₃O₈ over 1.4 metres. Three drill fences stepping out from discovery hole TF-25-16 (6.2 metres of 0.10% U₃O₈; see news release dated October 29, 2025) have expanded the mineralized footprint of the system to over 150 metres of strike length (Figure 2) now designated the “Tuning Fork Uranium Zone”. The zone is defined by continuous uranium mineralization and hydrothermal alteration along brittle reactivated structures at the Athabasca unconformity.
