IsoEnergy Ltd. provided an update on the results of winter 2024 exploration work on its eastern Athabasca Basin uranium properties. A total of 7,227 metres of drilling in 13 diamond drill holes on the Larocque East and Hawk projects confirmed ambient noise tomography (ANT) low velocity anomalies and identified new targets planned for testing during the summer exploration program set to commence in June 2024. Laroque East Project.

Seven drill holes (LE24-157 to LE24-163) tested a prominent ANT low velocity anomaly along the northeast extension of the Hurricane electromagnetic (EM) conductor corridor. Drilling intersected prospective brittle faults and alteration interpreted as the source of the ANT anomaly as well as intersecting the continuity of the Hurricane trend graphitic-pyritic basement lithologies up to 2,200m to the east. The ANT survey and results of the winter program have defined a large hydrothermal system that is typically associated with unconformity uranium deposits in the Athabasca basin.

Summer exploration is expected to fully evaluate this high priority target. Hawk Project. Five drill holes (HK24-09 to HK24-12 including one wedge hole) tested a prominent AN T low velocity anomaly coincident with a conductor corridor.

Drill holes HK24-10 to 12, intersected multiple graphitic basement hosted fault zones with spatially associated strong illite and chlorite alteration, and desilicification in the lower sandstone and upper basement. The presence of prospective faults and associated alteration has now been drill defined over a 1,600m long section of the underexplored 12km long corridor. Results from the winter program have elevated the prospectivity of Hawk to potentially host a large uranium deposit.

Ground geophysical surveys were completed at the Company's Larocque East, Hawk, and East Rim projects to further develop a pipeline of high-quality drill targets intended to be tested during the summer drill program. Winter Exploration Update. Hurricane, Larocque East Project.

Early in the winter program, a single line of stepwise moving loop time domain ground EM was completed at Larocque East to aid in drill targeting in Target Area A.LE24-162 was drilled to test the unconformity offset between drill hole LE24-157 and LE24-162. LE24-162A intersected a broad zone of bleaching below 213m and moderate structural controlled desilicification from 248 to unconformity at 267.2m. Drill hole LE24-162A has confirmed the unconformity elevation change with 17m unconformity offset over 20m between LE24-157 and LE 24-162A on section.

LE24-163, the last drill hole of the winter program, was drilled 200m west of LE24-161 and it successfully intersected the basement hosted graphitic and pyritic brittle fault at 387.5m and 509.7m. Additional ANT surveys and diamond drilling are planned at Larocque East during the summer program. Drilling is being planned to follow-up encouraging winter results in Area A, and will also target areas B, C and D. Drilling plans for Area D are expected to evolve as velocity models are interpreted from newly acquired ANT data.awk Project.

The winter drill program consisted of four drill holes collared from surface and one hole wedged off a parent hole. The 2024 winter drill program at Hawk successfully intersected and extended the structural corridor identified in the 2023 Hawk drill programs, with highly prospective structure and alteration identified along a corridor exceeding two kilometres in length.
