F3 Uranium Corp. announced final scintillometer results from its 2025 fall drill program on the Tetra Zone on the Broach Property. The program consisted of five diamond drill holes totaling 2,628m and extended the interpreted mineralized plunge length from 60m to 135m, an increase of 125%.
On the down-plunge (western) side, holes PLN25-220A and PLN25-220AW1 tested continuity but appear to have intersected the structure just above the expected mineralized zone, with radioactivity and broader shearing observed in PLN25-220A. On the up-plunge (eastern) side, PLN25-221 confirmed continuity, stepping out approximately 28m from PLN25-205. Samples from the drill core are split into half sections on site.
Where possible, samples are. standardized at 0.5m down-hole intervals. One-half of the split sample is sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK while the other half remains on site for reference.
Analysis includes a 63 element suite including boron by ICP-OES, uranium by ICP-MS and gold analysis by ICP-OES and/or AAS. The Company considers uranium mineralization with assay results of greater than 1.0 weight % U3O8 as "high grade" and results greater than 20.0 weight % U3 O8 as "ultra-high grade". All depth measurements reported are down-hole and true thicknesses are yet to be determined.
About the Patterson Lake North Project: The Company's 42,961-hectare 100% owned Patterson Lake North Project (PLN) is located just within the south-western edge of the Athabasca Basin in proximity to Paladin's Triple R and NexGen Energy's Arrow high-grade uranium deposits, an area poised to become the next major area of development for new uranium operations in northern Saskatchewan. The PLN Project consists of the 4,074-hectare Patterson Lake North Property hosting the JR Zone Uranium discovery approximately 23km northwest of Paladin's Triple R deposit, the 19,864-hectare Minto Property, and the 19,022-hectare Broach Property hosting the Tetra Zone, F3's newest discovery 13km south of the JR Zone. All three properties comprising the PLN Project are accessed by Provincial Highway 955.
