Eastern Athabasca Basin. Every major operator has ground here. The same geological structures that host the world's highest-grade uranium deposits run through this corridor.
IsoEnergy's Hurricane Deposit - 48.6 million pounds at 34.5% U3O8. Nothing else on Earth compares to this grade.
Cosa Resources intersected anomalous radioactivity in three drill holes at their Murphy Lake North joint venture with Denison Mines. The Cyclone trend structural corridor is over 100 metres wide, open 600+ metres along strike in both directions, at only 260 metres depth.
Cameco's La Rocque Zone - 29.9% U3O8 over 7.0m in drill hole Q22-040. 4 km south. The regional geological trend that hosts Hurricane extends along the western edge of our property.
609 hectares. Sitting between Hurricane, La Rocque, and Murphy Lake North. The Larocque Lake conductor trend runs along the western margin of our claims.
ML22-006 returned 0.065% U3O8 over 2.5m at the unconformity contact, including 0.242% U3O8 over 0.5m, within a 4.2m wide deformation zone at 322.5m depth.
No mineral resources have been defined on the property. Exploration results are preliminary.
EarthEx Geophysical Solutions refining conductor geometry between two known corridors. Spring 2026 drill program funded. Collar locations being finalized.
Murphy Lake
Property Overview
Murphy Lake is UraniumX's flagship property, covering 609 hectares in the northeast Athabasca Basin. The property is being explored under an option agreement with F4 Uranium Corp, through which UraniumX can earn up to 70% interest.
Geological Context
Intense hematite and limonite alteration in overlying sandstone, with graphitic shear zones in the basement - consistent with the unconformity-hosted uranium deposit model. Multiple conductors identified through airborne and ground geophysical surveys, with favorable basement geology featuring graphitic pelitic gneiss.
Financing
The $1.5M flow-through financing is directed toward Murphy Lake and Zoo Bay exploration programs, ensuring both properties are fully funded through the Spring 2026 field season.
Technical Report
Covered by an NI 43-101 technical report prepared by Terra Modelling Services (Louis F. Fourie, P.Geo.), available on SEDAR+.
