F3 Begins Summer Drilling at PLN Project After Completing 3D DCIP and Resistivity Survey Over Tetra Zone

F3 Uranium Corp. has launched its 2026 summer exploration program at the 100%-owned Patterson Lake North (PLN) Project in the Western Athabasca Basin. The initial phase of drilling will comprise approximately 4,000 metres, focusing on newly defined, drill-ready target areas on the Minto and Broach properties.

Drilling on the Minto property will advance the A4 trend near historic hole PLN14-021, which showed anomalous uranium and boron intersections. On the Broach property, 3D-DCIP and resistivity surveys have been completed over the Tetra Zone. Targeting is concentrated in the Patterson West Area and the Broach Lake South (BRS) Area.

Four prioritized targets surround the Tetra Zone, defined by EM conductors and gravity low anomalies. Historic core sampling in this area returned 423 ppm U with intense bleaching. The BRS Area hosts multiple drill-ready targets, including a newly reinterpreted steeply dipping conductor interpreted as the continuation of the Carter Trend. Management emphasizes a systematic, land-package-wide approach that previously delivered the JR and Tetra discoveries, now being applied to advance the most prospective targets in the field.

F3 Uranium Corp. (FUU) announced the execution of its previously outlined summer exploration program, initially detailed on June 2, 2026. The release confirms that the company is proceeding with its planned exploration pipeline and geophysical surveys.

The announcement does not disclose any new material discoveries, financial results, or strategic shifts. Market reaction is expected to be neutral to slightly positive, as the update validates management’s exploration strategy without introducing immediate market-moving catalysts. The market had already priced in the summer drilling plans.

F3 Uranium Corp. is a uranium exploration company focused on the Athabasca Basin in Saskatchewan, Canada. Its flagship Patterson Lake North (PLN) Project comprises a 42,961-hectare land package that includes the Patterson Lake North Property (JR Zone), the Minto Property, and the Broach Property (Tetra Zone).

The JR Zone hosts an initial Indicated Mineral Resource of 11.8 million lbs U3O8 at an average grade of 4.39%, which includes a high-grade domain of 10.8 million lbs at 12.23% U3O8. The Tetra Zone, located on the Broach Property, is a high-grade discovery showing strong radioactivity intercepts and genetic links to the JR Zone through shared hydrothermal regimes and alteration minerals. The company is in the exploration stage, with no revenue or proven ore reserves.
