F3 Uranium Corp. (TSXV: FUU) has completed a $20 million financing to fund a year-long drilling campaign at its Tetra Zone discovery in Saskatchewan's Athabasca Basin. The financing, which included $15 million in flow-through funds, brings the company's treasury to $30 million and eliminates near-term dilution pressure as the exploration program advances.

CEO Dev Randhawa explained the strategic shift toward Tetra Zone, which has emerged as the company's primary focus after the JR Zone failed to grow as anticipated. Despite JR's promising initial indicators, including peak grades of 4.5 meters at 50% uranium along a large conductor, the system has not delivered the expansion investors expected. Tetra Zone, by contrast, shows significantly greater potential with 60 meters of mineralization-three times what JR produced-sits just 12 kilometers from the Arrow and Triple R deposits along an apparent productive geological trend.

Recent drilling results support management's confidence in the discovery. The most recent hole intersected mineralization in a 15-meter step-out, with scintillometer readings exceeding 10,000 counts per second across 30+ meters. Chief Geologist Sam Hartmann estimates a 2.3-meter high-grade interval "will be well over a percent" when laboratory assays are returned. This successful step-out confirms both continuity and the geological model's predictive capability.

The technical understanding of Tetra has evolved considerably from initial interpretations. Unlike typical Athabasca deposits controlled by graphitic conductors, Tetra appears to be shear-zone-controlled, with mineralization in micaceous structures that generate weaker geophysical signatures. This realization explains why early drilling repeatedly intersected mineralization at unexpected depths and has enabled more confident targeting going forward.

F3's systematic approach involves methodical 25-50-100 meter step-outs to balance resource definition with expansion testing. With an experienced discovery team that previously found Waterbury and contributed to the Triple R discovery (sold for approximately $1 billion), the company is positioned to methodically test whether Tetra can join the ranks of significant Athabasca Basin uranium deposits. Regular drilling results are expected throughout 2026 as the delineation program progresses.
