IsoEnergy 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 following up high-grade winter 2026 results. 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% UO over 3.5 m, including 11.61% UO over 1.0 m, with additional intercepts of 2.75% UO over 0.5 m and 1.75% UO over 0.5 m, approximately 525 m east of the resource envelope. Summer drilling is designed to test the South Trend which intersected high grade mineralization along the J-L fault corridor. In addition to Larocque East, IsoEnergy has 14 prospective early-stage projects in the eastern Athabasca Basin on which a pipeline of drill targets is being developed.

IsoEnergy is pleased to announce that it has entered into an equity distribution agreement with Virtu Canada Corp. and Virtu Americas LLC. Pursuant to the Distribution Agreement, the company may distribute up to C$50M of common shares in the capital of the company, from time to time through the Agents. This ATM Program replaces the company's previous at-the-market equity program announced on June 2, 2025, which has since been terminated.
