IsoEnergy Ltd. announced the initial independent Mineral Resource Estimate for the Hurricane uranium deposit on its 100% owned Larocque East project in the eastern Athabasca Basin of Saskatchewan. Indicated Mineral Resources of 48.61 million lbs of U3O8 based on 63,800 tonnes grading 34.5% U3O8, including 43.89 million lbs U3O8 at an average grade of 52.1% U3O8 within the high-grade domain Inferred Mineral Resources of 2.66 million lbs of U3O8 based on 54,300 tonnes grading 2.2% U3O8 Indicated Mineral Resources are highly insensitive to cut-off grade due to the high-grade and compact nature of the Hurricane Deposit. The Hurricane zone measures 375 metres along strike, up to 125 metres wide, and up to 12 metres thick.

The high-grade domain, which contains 43.89 million pounds of U3O8 at an average grade of 52.1% U3O8, occupies an area 125 metres long and is up to 63 metres wide and up to 4.5 metres thick. Mineralization at Hurricane occurs at the sub-Athabasca unconformity approximately 325 metres vertically below surface and is essentially horizontal. East-west trending, steeply north-dipping basement rocks underlying Hurricane host centimetre- to metre-scale fault zones preferentially occurring at contacts between graphitic and non-graphitic units.

Mineralization is controlled by the intersection of these fault zones with the sub-Athabasca unconformity resulting mineralization elongated in its east-west dimension. Mineralization ranges from disseminated to massive and includes very high-grade intersections, including 38.8% over 7.5 metres in LE20-76 between 322.5 and 330 metres which includes a subinterval averaging 74.0% U3O8 over 3.5 metres from 324.0 to 327.5 metres. Additional Hurricane drilling highlights are presented in Table 3, including intercepts from high-grade domain.

The Mineral Resource Estimate was defined using 52 diamond drill holes totaling 20,387 metres and using 785 samples. Uranium grade data comprises chemical assays of half split drill core samples collected on site by IsoEnergy staff. All samples were assayed at the independent Saskatchewan Research Council (SRC) Geoanalytical Laboratory of Saskatoon, an ISO/IEC 17025 accredited facility.

Samples were analysed using a combination of inductively coupled plasma - mass spectrometry (ICP-MS), inductively coupled plasma - optical emission spectrometry (ICP-OES), and partial or total acid digestion of one aliquot of representative sample pulp per analysis. Mineralized samples were analysed for U3O8 by ICP-OES. Quality Assurance and Quality Control (QA/QC) measures include the field insertion of Certified Reference Material (CRM) standards, CRM blanks, and duplicate samples.

The Mineral Resource Estimate grade data was obtained only from chemical assays; no radiometric data were utilized.
