IsoEnergy Commences 8,000 Metre Summer Drill Program at the Larocque East Project, Athabasca Basin

(TSX: ISO) IsoEnergy Ltd. announced the commencement of its 2026 summer exploration program on the Larocque East project, which hosts the high-grade Hurricane deposit in the eastern Athabasca Basin, Canada. The program is planned to comprise approximately 8,000 m of diamond drilling across up to 20 drill holes, focused on the Hurricane South Trend. Hurricane hosts a current Mineral Resource of 48.6 Mlb U3O8 at 34.5% U3O8 Indicated, and 2.7 Mlb U3O8 at 2.2% U3O8 Inferred. Winter 2026 drilling returned 4.21% U₃O₈ over 3.5 m, including 11.61% U₃O₈ over 1.0 m in hole LE26-248, with additional intercepts of 2.75% U₃O₈ over 0.5 m in LE26-234 and 1.75% U₃O₈ over 0.5 m in LE26-243. The deposit is located approximately 40 km northwest of the McClean Lake mill and features relatively shallow mineralization at approximately 325 m depth. Airborne MobileMT surveys and ground field work are planned to develop drill targets on four prospective early-stage projects, as well as the western portion of Larocque East. The company projects that summer 2026 drilling will follow up along the South Trend, focusing on step-outs from LE26-248 and the along-strike extension to the east.
