Greenridge Provides Update on 2025 Athabasca Basin Region Exploration Activities

Executive Summary

• Greenridge provided a comprehensive update on 2025 exploration activities across six Athabasca Basin projects, highlighting geophysical surveys, drill programs and notable assay anomalies.
• The company outlined future work plans for 2026, including additional drilling at Hook‑Carter (potential to earn an extra 5% interest) and continued surface and airborne EM work at several properties.
• No financial transactions or earnings were disclosed; the update is primarily operational and forward‑looking.

Key Details

• Hook‑Carter Uranium Project – Completed a six‑line MLTDEM ground EM survey in fall 2025, refining drill targets for a planned 2026 campaign. Greenridge can earn an additional 5% working interest (total 25%) by spending $3 M on exploration before Nov 2026.
• Carpenter Lake Uranium Project – Executed eight diamond holes (1,368 m total) in Sep 2025; intersected anomalous radioactivity and pathfinder geochemistry (U, As, Ni, Cu, Co, Pb, Zn, B). Permit allows up to 30 drill holes, valid until Apr 1 2026.
• Sabre Uranium Project – Conducted a spring‑2025 MobileMT airborne EM survey (1,536 line‑km at 200 m spacing) covering 232 km²; data being integrated into a 3‑D geological model. Drilling permit for up to 10 holes, valid through Nov 30 2027.
• McKenzie Lake Uranium Project – Axiom/NRG performed a 365 line‑km Xcite™ airborne EM survey (200 m spacing) in 2025, mapping a major north‑south fault and discrete conductors. Permit for geophysics and surface work valid to Mar 31 2027.
• Bradley Lake Uranium Project – Acquired via ALX Resources (Dec 2024). 2025 Xcite™ HTDEM airborne survey (201 line‑km at 100 m spacing) identified a conductive zone with coincident radiometric anomalies under evaluation. Permit for surface work valid to May 31 2027.
• Flying Vee Nickel Project – Completed a 726 line‑km Xcite™ airborne EM survey (100 m spacing) in 2025, detecting conductors linked to known nickel and gold showings; radiometrics indicated possible uranium/potassium pathfinders. Permit for up to 100 drill holes, valid to Mar 31 2028.
• Qualified Person Review – Technical information reviewed and approved by Luke van der Meer, B.Sc., P.Geo., qualified under NI 43‑101.
