IsoEnergy Reports Promising Results from Winter Drilling at Hurricane Deposit, Highlighting Enhanced Radioactivity in New Fault Zone
IsoEnergy Ltd. has recently concluded a successful winter drilling campaign at its Larocque East project, known for hosting the high-grade Hurricane deposit situated in the eastern Athabasca Basin, Canada. The 2026 drilling program proved to be a significant extension from the initial plan, increasing from 13 to 17 diamond drill holes, totaling 6,804 meters in length due to positive preliminary results. This expansion allowed for an exploration of potential resource growth and some greenfield targets along the Larocque Trend.
Among the standout results, drill hole LE26-248 intersected an extraordinary 30,050 counts per second (cps) over an interval of 1.0 meter, with localized readings surpassing 65,500 cps, all located within the newly identified L Fault Zone. This finding is a critical indicator of the high prospectivity within the South Trend of the Hurricane deposit. Furthermore, mineralization has been detected through multiple holes extending as much as 540 meters east of the known deposit footprint, showcasing the expanding potential of this trend.
IsoEnergy’s current estimates place the Hurricane deposit at 48.6 million pounds of U3O8 at an average grade of 34.5% U3O8 indicated and 2.7 million pounds at 2.2% U3O8 inferred. This mineral resource, combined with the successful positioning of drill holes, highlights the efficient exploration and future development possibilities facilitated by the region's well-established infrastructure, located just 40 kilometers from the McClean Lake mill and featuring relatively shallow deposits found at approximately 325 meters.
Dan Brisbin, the Vice President of Exploration for IsoEnergy, expressed optimism about the results from LE26-248 and the confirmed elevated radioactivity in adjacent holes, stating that they underscore the burgeoning potential of the Hurricane South Trend. These results will guide the team in reinterpreting the geological structures responsible for uranium mineralization and suggest that underexplored regions may hold even more resources.
As the project progresses, assay results from the winter drilling campaign are anticipated shortly, which will further inform ongoing exploration plans. The company is gearing up for continued drilling efforts in the summer, aimed at testing both the North and South trends of the Hurricane deposit.
The exploration program particularly focuses on identifying additional mineralized fault strands across the Hurricane South Trend, which appears to represent a broader, more promising corridor than previously understood. Notable drill intersections included:
The strategic approach employed during the exploration drilling solidly positions IsoEnergy to contribute to the growing confidence in the mineral prospects of the Hurricane deposit and its surrounding areas. With a well-defined operational framework, including overcoming geological challenges and enhancing exploratory accuracy and mining efficiencies, the company is committed to realizing and capitalizing on the area’s rich potential.
As such, continued drilling in summer 2026 will facilitate a deeper examination and follow-up on the encouraging results, with the overarching aim of expanding resource estimates at the Hurricane deposit significantly. Looking ahead, the exploration team anticipates a proactive exploration agenda to capitalize on these findings, allowing IsoEnergy to enhance its standing within the uranium sector significantly.

- - LE26-241 (100 meters east of LE26-248) achieved notable radioactivity in the lower 8 meters of sandstone above the unconformity, returning values of up to 3,712 cps over a 0.5-meter interval.
- - LE26-243 (180 meters east of LE26-248) also registered significant readings of 10,000 cps over a 0.5-meter interval from within the lower 6 meters of sandstone above the unconformity.
- - LE26-234 (560 meters east of LE26-248) recorded two significant intervals of elevated radioactivity, including 6,450 cps over 0.5 meters within altered sandstone, showcasing substantial uranium potential.
