Foremost Clean Energy Successfully Completes 2,695 m Drill Program at its Murphy Lake South Uranium Property

Executive Summary

• Foremost Clean Energy completed a seven‑hole, 2,695 m diamond drill program at the Murphy Lake South Uranium Property, the first since 2017.
• All holes intersected the targeted graphitic structural corridor with strong hydrothermal alteration, elevated radioactivity and shallow unconformity depths (200–350 m), confirming the classic setting for Athabasca‑style unconformity uranium systems.
• Core samples have been sent to the Saskatchewan Research Council for assay; results are pending.

Key Details

• Program Scope: 7 holes, total depth 2,695 m; first systematic drilling at Murphy since 2017, designed to follow up historic Denison targets (MP‑17‑19, MP‑15‑03, MP‑16‑11, MP‑16‑17).
• Geological Highlights:
• Broad zones of hydrothermal alteration extending ~600 m along the Athabasca unconformity.
• Multiple intervals of elevated gamma radiation (2–3× background; 205–208 cps) within graphitic basement and sandstone above the unconformity.
• Shallow unconformity depth (200‑350 m) reduces drilling costs for future programs.
• Drill Hole Summaries:
• MP25‑001B: 17.5 m fault zone at 258.5 m; unconformity at 275.4 m; second hematite‑altered zone 4.5 m (289.6‑294.1 m).
• MP25‑002: 2.3 m clay‑altered gouge at 253.3 m; 9.8 m fault zone with hematite/clay starting 270.6 m; finished at 344.3 m.
• MP25‑003: Strong clay alteration 200‑350 m; hematite zone 2 m at 258‑260 m; graphitic shear zone 273.2‑286 m with 208 cps radioactivity over 1 m (274.6‑275.6 m).
• MP25‑004: Moderate bleaching to 105 m; fracturing/clay alteration 263‑276.6 m; hematite zone 4 m just above unconformity.
• MP25‑005: Two clay‑altered fault zones (3.7 m & 3.5 m) at 47‑57 m; extensive clay alteration wrapping unconformity 245‑269 m; finished at 428.1 m.
• MP25‑006: Multiple small clay fracture zones; elevated radioactivity 206 cps over 1.2 m in sandstone (251.7‑252.9 m); unconformity at 259.3 m; finished at 404.8 m.
• MP25‑007: Two altered fracture zones (2.3 m & 3.1 m) starting 248 m; unconformity at 255.4 m; graphitic shear zone with 205 cps over 2 m (282‑284 m).
• Assay Status: All core submitted to SRC for ICP‑MS/OES analysis; results expected in coming weeks.
• Next Steps: Integration of assay data into a comprehensive geological model; planning of follow‑up drilling to advance the ~400 m mineralized corridor.
• Investor Webinar: Red Cloud Financial Services will host a live webinar on 2025‑11‑18 (2:00 PM ET) with Foremost’s President & CEO Jason Barnard and VP Exploration Cameron MacKay to discuss results and future catalysts. Registration link provided in release.
