en.Wedoany.com Reported - On April 22, 2026, Canadian F3 Uranium Corp. completed its winter diamond drilling program at the Tetra Block of the Patterson Lake North Project in the Athabasca Basin, Saskatchewan. This step-out drilling program comprised six drill holes, three of which successfully intersected uranium mineralization, validating the geological structural model for the block and indicating continued exploration potential along strike and down-dip.
Drill hole PLN26-226, located 275 meters along strike from a previous high-grade mineralization zone, returned a 0.5-meter interval with radioactivity up to 1,400 cps. Integrated structural, mineralogical, and geochronological studies suggest a genetic link between the Tetra Block and the company's existing high-grade JR Zone, enhancing the regional discovery potential of the overall PLN Project. Geological interpretation indicates that uranium mineralization in this block is primarily hosted in fracture-controlled breccias and has undergone multiple phases of hydrothermal activity.
The company has secured funding for its 2026 exploration campaign, which plans to apply the refined geological model to broader target areas, including the A1/B1 trend and the Harrison Fault, to search for additional high-grade pods and potential deposits. Concurrently, drill core resistivity data will be utilized to refine the geophysical model, improving target delineation accuracy in non-traditional geological settings.
The Patterson Lake North Project covers a total area of approximately 42,961 hectares in the southwestern Athabasca Basin, proximal to several known high-grade uranium deposits. The recent drilling discovery in the Tetra Block further confirms the potential for uranium mineralization in non-graphitic environments within this region, providing new rationale and direction for the company's ongoing exploration in the Athabasca Basin.
