11:00 Uhr | Newsfile
F3 Uranium Corp. (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce final assay results of the 2025 Tetra Zone drill program on the Broach Property including PLN25-219A (See NR November 10, 2025 and January 13, 2026) which returned a main mineralized interval of 13.0m of 0.28% U3O8, including three high grade sections with 3.0 m of 1.19% U3O8 from 396.5 to 399.5m, 0.5m of 1.07% U3O8 from 404.0 to 404.5m and 1.0m of 1.60% U3O8 from 406.5 to 407.5 m.
Sam Hartmann, Vice President Exploration Comment:
"We are pleased to release the final assays for Tetra Zone from the Fall 2025 program. PLN25-219A returned a broad 13.0-metre interval grading 0.28% U₃O₈ that includes several higher-grade sub-intervals, totaling 4.5m of composite high-grade mineralization. These results, together with the confirmation of continuity in PLN25-221, provide important geological information that will help refine our understanding of the Tetra Zone's controls and geometry. A follow-up drill program is currently in progress at the Tetra Zone utilizing one diamond drill."

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 % U3O8 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.
