IsoEnergy Ltd. provided an update on the results of summer 2023 exploration work on its eastern Athabasca Basin uranium properties. Summer Program Highlights: 5,270 metres of drilling were completed in 11 drill holes on the Larocque East, Hawk and Ranger projects. Mineralization was intersected in the west end of the Hurricane deposit at Larocque East, and prospective intervals of strong structural disruption, clay alteration and desilicification were intersected on conductive corridors with significant untested strike length at Hawk and Ranger.

At Laroque East, Drill hole LE23-155, drilled in the southwest portion of the Hurricane deposit to upgrade confidence in continuity of mineralization to the western border of the property, intersected 8.5 meters averaging 4.1% U3O8 between 325.0 and 333.5m downhole. This interval includes an intercept of 6.8% U3O8 over a 1.0 m interval from 327.0 to 328.0m and a higher-grade interval of 23% U3O8 over 1.0 m from 331.5 to 332.5m. Innovative Ambient Noise Tomography (ANT) surveys were completed on thearocque East, Hawk and East Rim projects in collaboration with FLEET.

A compelling 1-kilometre-long ANT target has been defined along strike of the Hurricane deposit with the same footprint as the feature associated with Hurricane. Drill hole HK23-08 at Hawk, intersected a significant fault zone that offsets the unconformity by 16.5 metres and is spatially associated with strong illite and chlorite alteration, and desilicification in the lower sandstone and upper basement. HK23-08 was drilled 850 metres south of a 2- kilometre-long ANT velocity anomaly that is situated within a north-northeast trending regional corridor defined by a magnetic low and coincident ZTEM conductivity.

Drilling highlights include mineralization intersected in LE23-155 in the southwestern portion of the Hurricane deposit, which suggests that section of the orebody extends to the western border of the Property. Overall, the summer program has continued IsoEnergy's systematic approach to advancing its high-quality portfolio of properties in the Eastern Athabasca Basin and has provided the Company with an exciting set of targets with significant discovery potential to focus on in 2024, starting with upcoming winter program, for which planning is already underway.
