Prior to the temporary suspension, four of a planned 20 holes were completed with all holes intersecting mineralization, including 43,160 cps over 0.5 m, confirming the continuity of the newly identified L Fault Zone along the Hurricane South Trend (Table 1). IsoEnergy's summer program is targeting 8,000 m of diamond drilling, in up to 20 drill holes, focused on the highly prospective Hurricane South Trend (Figure 1).

Hurricane hosts a current Mineral Resource of 48.6 Mlb U3O8 at 34.5% U3O8 Indicated, and 2.7 Mlb U3O8 at 2.2% U3O8 Inferred (See "Qualified Person Statement" below). The Project benefits from excellent infrastructure, located approximately 40 km northwest of the McClean Lake mill, and features relatively shallow mineralization at approximately 325 m depth, supporting efficient exploration and future development optionality. The Deposit is located on the Larocque Trend, an important regional structure that also hosts other notable high-grade occurrences including those on Cameco and Orano's Dawn Lake joint venture. 

Highlights

  • Mineralization Confirmed Along Strike on the L Fault Zone: LE26-250, drilled approximately 75 m east of the high-grade winter 2026 intercept in LE26-248 (4.21% U3O8 over 3.5 m, including 11.61% U3O8 over 1.0 m), intersected 11,075 cps over 3.5 m, including 43,160 cps over 0.5 m (all radioactivity reported herein are averages of three points measured over 0.5 m on drill core with an RS-125 spectrometer), extending the continuity of mineralization east of LE26-248 along strike on the L Fault Zone on the Hurricane South Trend.
  • Mineralization Intersected in Every Completed Hole: All four completed drill holes returned elevated radioactivity, reinforcing the continuity and prospectivity of the Hurricane South Trend identified during the 2025 and winter 2026 results along the Hurricane South Trend.
  • Summer Drilling Resumes: Approximately 2,100 m of drilling had been drilled across four completed holes and two in progress prior to the temporary suspension due to nearby wildfire, with two additional holes in progress. The Company remains on track to complete the ~8,000 m, 20-hole summer program as planned.
  • Strategic Land Position Strengthened: 61,830 ha were added through staking in 2026 across the Dorado Joint Venture and IsoEnergy's Larocque West, Hawk, Evergreen, East Rim and Ledge projects, enhancing exposure to prospective uranium targets across the eastern Athabasca Basin (Figure 2).
  • Coverage of Prospective Corridors Expanded: The addition of 31,293 ha under option from GEM Oil Inc. extends the Larocque West project, increasing coverage of highly prospective structural corridors and regional exploration targets.
