IsoEnergy and Purepoint Uncover Stronger Uranium Zone at Dorado, Drill Returns 14-Meter Interval With Peak of 110,800 CPS

IsoEnergy Ltd. (NYSE:ISOU) (TSX:ISO) ("IsoEnergy") and Purepoint Uranium Group Inc. (TSXV:PTU) (OTC:PTUUF) ("Purepoint") are pleased to report continued strong results from drilling at their 50/50 Dorado joint venture project ("Dorado" or the "Project"), located in Saskatchewan's world-class Athabasca Basin (Figure 1). The most recent drill hole, PG25-07A, stepped out approximately 70 metres northeast of the "Nova Discovery" intercepts at the Q48 target area and returned stronger mineralization, with an average of 11,100 counts per second (CPS) measured on a Mount Sopris 2PGA-1000 downhole radiometric probe across a much wider interval of 14.0 metres, including a peak reading of 110,800 CPS.

The recent Nova Discovery results further define the mineralized trend at the Q48 target as a steeply dipping, uranium-bearing structure hosted within the basement rocks, underscoring the potential scale and strength of the system emerging at Dorado. All assays from the current program, including holes PG25-04 and PG25-05, are pending on a rush basis and will be disclosed once available.

Highlights

• PG25-07A intersected a continuation of the Nova Discovery uranium basement hosted mineralization approximately 70 metres northeast of PG25-05 and 60 metres below the unconformity, averaging 11,100 CPS over 14.0 metres with a peak of 110,100 CPS.
• The Nova Discovery mineralization at Q48 remains open to the northeast, the direction of increasing radioactivity, but wet marsh ground conditions currently prevent further drilling in that direction. Follow-up drilling is expected to resume this winter, when frozen ground allows for more efficient land-based access.
• The drill rig has now been mobilized to the Turaco target, located approximately 8 km northeast of the Q48 target within the Dorado project. Up to four holes are planned at Turaco as part of the 5,400-metre drill program approved by the joint venture partners for 2025.
