IsoEnergy (ISOU): Drilling hits up to 15.4% U3O8 east of Hurricane deposit
Step-out drilling at Hurricane hits up to 15.4% U3O8 500 m east of deposit; LE26-250 returns 3.86% U3O8 over 3.5 m.
What this filing says
IsoEnergy reported assay results from its 2026 summer drilling at the Larocque East project, confirming high-grade uranium in several holes along the Hurricane South Trend, including one about 500 m east of the deposit. For a shareholder, the results extend mineralization beyond the existing deposit footprint, which may support future exploration, though the release describes these as early drill results rather than a resource update.
Key figures
- Best step-out intercept grade
- 15.4% U3O8 over 0.5 m
- Distance east of Hurricane
- 500 m
- Current Indicated resource
- 48.6 Mlb U3O8 at 34.5% U3O8
- Current Inferred resource
- 2.7 Mlb U3O8 at 2.2% U3O8
- Deposit depth
- approximately 325 m
- Distance to McClean Lake mill
- approximately 40 km
Positive for shareholders
- Step-out drilling intersected high-grade uranium beyond the existing Deposit footprint on the L and K fault zones.
- Mineralization is relatively shallow at about 325 m depth, which the company says supports efficient exploration and future development options.
- Project benefits from infrastructure located roughly 40 km from the McClean Lake mill.
Negative for shareholders
- Several of the highest-grade results come from very short intervals of 0.5 m or 1.0 m.
- Results are assay results from exploration drilling and do not themselves constitute a new resource estimate.

Key terms
- U3O8:
- Triuoxide of uranium, the standard form in which uranium concentrate is measured and sold.
- Step-out drilling:
- Drilling placed outside the known edge of a deposit to test whether mineralization continues.
- Indicated and Inferred resources:
- Mineral resource categories reflecting decreasing levels of geological confidence, with Indicated more certain than Inferred.
- Unconformity:
- A geological boundary where younger rock layers sit on older eroded rock, often a host zone for Athabasca uranium deposits.
FAQ
Where were the highest-grade intersections reported by IsoEnergy?
The release reports up to 15.4% U3O8 over 0.5 m in hole LE26-254, about 500 m east of the Hurricane deposit on the L fault zone.
Does the release update IsoEnergy's resource estimate for Hurricane?
No, the release restates the existing Mineral Resource of 48.6 Mlb U3O8 at 34.5% Indicated and 2.7 Mlb at 2.2% Inferred and reports new assay results from the drilling program.
