F3 Uranium Corp. (TSX-V: FUU)(OTC: FUUFF) — currently trading undiscovered around C$0.25 per share in a robust uranium market — is continuing to build momentum across its flagship, 100%-owned Patterson Lake North (PLN) project in Saskatchewan’s prolific Athabasca Basin.
With multiple zones now returning strong assay results, a maiden resource estimate (MRE) is also on the near-term horizon.
Strategically located on the southwestern edge of the basin, F3 Uranium’s (“FUU”) PLN project spans 42,961 hectares. The property is anchored by the JR Zone discovery just 23 km northwest of Paladin’s Triple R deposit and 30 km northwest of NexGen’s Arrow deposit — placing it squarely within one of the most promising new uranium development corridors in the world.
FUU has announced that geological re-logging and maiden geochemical sampling of historical holes at the Broach property [PLN Project] — located 1.2 km southeast of the newly discovered Tetra Zone — returned a standout uranium interval of 423 ppm over 0.5 meters.
That result, from a previously unassayed 2016 hole, marks the highest uranium value ever recorded at PLN outside of the JR and Tetra Zones. It also significantly extends the interpreted mineralized corridor now being actively drilled at Tetra.
The Tetra Zone, first revealed in April 2025 with discovery hole PLN25-205, returned a peak radioactivity of 37,700 cps over 0.56 meters — one of the highest ever recorded in the Clearwater Domain.
Assays have now confirmed the discovery with 2.50% U₃O₈ over 1.0 meter within a broader 22.5-meter interval averaging 0.26% U₃O₈, marking a major high-grade breakthrough in a historically overlooked area.
A 32-meter step-out hole (PLN25-210) to the northwest returned 21 meters of composite radioactivity, validating both geological models and the potential scale of this emerging high-grade system.
Drilling is ongoing with one diamond rig and one sonic drill focused on delineating the zone’s orientation and expanding the footprint.
Meanwhile, final assay results from the 2024 JR Zone drill campaign — located ~12 km to the north — include PLN24-184, which returned 13.0 meters of 3.2% U₃O₈, including a high-grade interval of 2.5 meters at 13.7% U₃O₈.
Those results will directly inform the project’s maiden mineral resource estimate (MRE) now underway with SLR International and on track for delivery in Q4 2025.
The JR Zone, discovered in late 2022, has been steadily advanced through infill and step-out drilling, and the upcoming MRE will represent a major milestone in its evolution.
Exploration efforts also continue across the broader PLN property, including the A1 Extension and B1 Shear Zones where geochemical and structural indicators continue to highlight high-priority untested targets.
Notably, hole PLN24-187 intersected 70 ppm uranium over 8.5 meters along the A1 Extension — viewed as a potential continuation of the JR Zone’s controlling structure.
To support this dual focus on expansion and resource definition, F3 recently closed a bought-deal private placement of 29.2 million flow-through shares for gross proceeds of ~C$7 million.
With uranium prices holding firm amid surging global demand — and with the macro backdrop strengthening further via Small Modular Reactor (SMR) development, AI data center demand growth, and utility contracting pressures — F3 Uranium is advancing on multiple fronts.
Speculators can look forward to ongoing drill results from the Tetra Zone, potential follow-up at the A1-B1 Zones, and the delivery of a high-impact maiden resource estimate at the JR Zone — all pointing to a catalyst-rich second half of 2025.
For a closer look, our own Gerardo Del Real of Junior Resource Monthly caught up with F3 Uranium president Ray Ashley to discuss the significance of the Tetra Zone discovery, progress toward the JR Zone resource estimate, and what investors can expect in the second half of 2025. Please enjoy!
