IsoEnergy Commences 2025 U.S. Exploration Program

TORONTO, Sept. 17, 2025 /CNW/ - IsoEnergy Ltd. ("IsoEnergy" or the "Company") (NYSEAmerican:ISOU) (TSX:ISO.TO) is pleased to announce the launch of its 2025 U.S. exploration program, focused on advancing its uranium projects in southeast Utah. The program will begin with completion of ten surface rotary holes with core tails, totaling 15,000 feet on the Flatiron claims, located in the Henry Mountains uranium district, approximately seven miles northwest of the Company's past-producing Tony M uranium mine (Figure 1). This initial drill program is designed to follow-up on historical, regional exploration conducted by Plateau Resources in the early 1980s and represents IsoEnergy's first phase of testing at Flatiron. In addition to drilling at Flatiron, IsoEnergy will continue fieldwork at its Daneros and Sage Plain projects (Figure 2). This work is aimed at better defining the sedimentary framework that controls mineralization at both regional and mine scales. This geological work is expected to guide future exploration.
