IsoEnergy Intersects Strongly Elevated Radioactivity in Multiple Holes Immediately Along Strike of Hurricane and In Step-Out Target Area D, 2.8 km East

TORONTO, April 23, 2025 /CNW/ - IsoEnergy Ltd. ("IsoEnergy" or the "Company") (TSX:ISO.TO) (OTCQX:ISENF) is pleased to announce the completion of its winter drilling program at the Larocque East Project (the "Project"), located in the eastern Athabasca Basin. The Company successfully completed 17 diamond drill holes, totaling 6,396 m, along the Larocque Trend ("Larocque Trend"), an important regional structure that hosts the Hurricane Deposit ("Hurricane" or the "Deposit") containing a current Indicated Mineral Resource of 48.6 Mlbs at 34.5% U₃O₈ and an Inferred Mineral Resource of 2.7 Mlbs at 2.2% U₃O₈ (See "Qualified Person Statement" below). The Larocque Trend also hosts other notable high-grade occurrences including those on Cameco and Orano's Dawn Lake joint venture. The Company's drilling intersected strongly elevated radioactivity, in five holes, along the eastern extensions of the Hurricane Deposit main and south trends, as well as at Area D, 2.8 km east of Hurricane, highlighting the potential for additional zones of uranium mineralization both immediately on strike of Hurricane and regionally along the 9 km of the Larocque Trend on the Project.
