Kelowna, British Columbia--(Newsfile Corp. - October 8, 2025) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce a fall drill program at its 100% owned Broach Lake Property, on the recently discovered high-grade Tetra Zone (see NR August 5, 2025).
This 3,000m diamond drilling fall program is designed to test the extent of the uranium mineralization which is currently highlighted by PLN25-205, which returned a 1.0m high grade interval with 2.50% U3O8 within a 22.5m mineralized main interval averaging 0.26% U3O8 and PLN25-217, which intersected a total of 67.0m composite anomalous radioactivity including 49.0m of continuous radioactivity (see Map 1).
Ground EM surveying has also been completed, and 3D inversions are in progress; these results will be incorporated into the targeting model for regional drill targeting along strike.
Sam Hartmann, Vice President Exploration, commented:
"We are excited to resume drilling at Tetra now that ground geophysics has been completed, and plan to focus this fall drill program at a deposit scale on the Tetra Zone, initially stepping out from high grade mineralization as in PLN25-205 and the significant intervals of radioactivity in PLN25-217. The unique geological setting of the Tetra Zone with differs from many basement hosted uranium deposits in the area, is also reflected in the geophysical responses, where weaker conductivity is associated with less resistive rocks associated with a structural damage zone hosting the Tetra Zone."

The natural gamma radiation detected in the drill core, as detailed in this news release, was measured in counts per second (cps) using a handheld Radiation Solutions RS-125 spectrometer which has been calibrated by Radiation Solutions Inc. The Company designates readings exceeding 300 cps on the handheld spectrometer (occasionally referred to as a scintillometer in industry parlance; this colloquial usage stems from historical naming conventions and the shared functionality of detecting gamma radiation between a spectrometer and a scintillometer)-as "anomalous", readings above 10,000 cps as "highly radioactive", and readings surpassing 65,535 cps as "off-scale". However, readers are cautioned that spectrometer or scintillometer measurements often do not directly or consistently correlate with the uranium grades of the rock samples and should be regarded solely as a preliminary indicator of the presence of radioactive materials.
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. 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.
