[{"type":"text","content":"F3 - Hits 2.5m of 10.2% U3O8 Within 3.4% over 8.5m at JR ZoneTetra Assays: 26.5m of mineralization including 1.04% over 0.5mKelowna, British Columbia--(Newsfile Corp. - December 15, 2025) - F3 Uranium Corp. (TSXV: FUU) (OTCQB: FUUFF) (\"F3\" or \"the Company\") is pleased to announce final assay results of the 2025 JR Zone drill program on the PLN Property including PLN25-200 (See NR March 18, 2025) which returned 8.5m of 3.4% U3O8, including a high grade core with 2.5m of 10.2% U3O8. At the Tetra Zone, assays confirm the presence of high grade uranium mineralization 55m along strike from discovery hole PLN25-205 with PLN25-217 returning a 0.5m high grade interval with 1.04% U3O8 within a 3.50m mineralized interval averaging 0.30% U3O8 from 400.0m to 403.5m. Total composite mineralization of 26.5m was intersected between 340.5 to 406.5m.Exploration focused mainly on the area around Tetra Zone with PLN25-207 intersecting 0.06% U3O8 between 621.0 to 621.5m. This deep intersect is interpreted to be associated with the same shear system which hosts the Tetra Zone over 200m to the west. Sam Hartmann, Vice President Exploration, Comment:\"We are pleased to release the final assays for JR Zone, where the last two holes for inclusion into the upcoming maiden resource estimate were completed earlier this spring. At the Tetra Zone, we are releasing the second batch of assays since the initial high grade discovery hole (PLN25-205) assays, including an interval with high grade mineralization with 1.04% over 0.5m, confirmation of additional high-grade uranium mineralization at the Tetra Zone, 55m along strike from the discovery hole. Exploration geochemistry around the Tetra Zone continues to return strongly anomalous uranium values with 0.06% U3O8 at depth in PLN25-217, approximately 200m away from Tetra Zone highlighting the prospectivity and size potential of the mineralized system.\"PLN Property JR Zone Assay Highlights:PLN25-200 (line 045S):8.5m @ 3.4% U3O8 (234.0m to 242.5m), including2.5m @ 10.2% U3O8 (236.0m to 238.5m), further including1.0m @ 20.7% U3O8 (237.5m to 238.5m), and5.5m @ 0.05% U3O8 (246.5m to 252.0m)Broach Property Tetra Zone Assay Highlights: PLN25-217 (line 11280S):0.5m @ 0.06% U3O8 (340.5m to 341.0m), and3.5m @ 0.07% U3O8 (355.0m to 358.5m), and1.5m @ 0.05% U3O8 (361.5m to 363.0m), and1.0m @ 0.07% U3O8 (365.0m to 366....
