F3 Uranium Corp. has intersected strong basement bleaching and prospective structures in the first two drill holes of its 2026 summer exploration program at the 100% owned Patterson Lake North Project in the Western Athabasca Basin, Saskatchewan.

Drill hole PLN26-229, positioned as a 950-metre step-out east of the Tetra Zone discovery on the Broach Property, cut strong bleaching at the top of the basement. The hole reached a total depth of 695 metres with an unconformity depth of 161.8 metres and exhibited no radioactivity exceeding 300 cps.

Paladin Energy Ltd. reported a new high-grade uranium discovery at its Patterson Lake South project within the surrounding district in June 2026, intercepting 8.0 metres averaging 1.75% U3O8 at the Atlas discovery.

“PLN26-229 represents a significant 950 m step-out from Tetra, and the presence of very similar basement bleaching of that intensity this far out demonstrates that the alteration system is considerably more extensive than the area immediately surrounding the Tetra discovery. This is precisely the outcome we hoped our targeting would deliver. Target Area 1 has long been one of our priority targets, and we plan to follow it up with at least one additional hole this summer that incorporates all the new data from this intercept.”

“A combination of geophysics has outlined at least four prioritized targets across the Tetra zone area of Broach, and the alteration observed in this PLN26-229 almost a kilometer away is visually very similar to that seen at Tetra, suggesting a comparable process may extend well beyond the original discovery itself.”

Meanwhile, drill hole PLN26-228 tested the A4 conductor on the Minto Property, reaching a total depth of 845 metres with an unconformity depth of 396.4 metres. The hole returned handheld scintillometer readings exceeding 300 cps across two 0.5-metre intervals: 688.0 to 688.5 metres with a peak of 480 cps, and 809.5 to 810.0 metres with a peak of 380 cps.

The 42,960-hectare Patterson Lake North Project comprises three properties: the Patterson Lake North Property hosting the JR Zone, the Minto Property, and the Broach Property hosting the Tetra Zone. F3 Uranium plans summer drilling to advance the target area around historic drill hole PLN14-021 on the A4 trend within the Minto Property, as part of an initial 4,000-metre drill program.
