F3 COMMENCES 2025 DRILL PROGRAM AT PLN

F3 Uranium Corp. has started drilling as part of the $6-million 2025 winter exploration program on the Patterson Lake North (PLN) project, with the initial focus on the JR zone, where drill hole PLN24-176 returned 7.5 metres of 30.9 per cent triuranium octoxide, including 4.5 m of 50.1 per cent U3O8 (see news release dated Dec. 3, 2024). Initially, exploration drilling for a new zone of mineralization will begin on the continuation of the A1 structure around PLN24-152 -- an exploration hole with the best geochemistry to date -- where a seven m mineralized interval assayed up to 0.051 per cent U3O8 (see news released dated July 30, 2024), approximately 2,800 m south of the JR zone.

Sam Hartmann, vice-president of exploration, commented: "We are excited to get back to work and continue drill exploration at the PLN property; this will consist of JR zone drilling in high-reward areas where we stand to add value, starting with the exceptional high grade cored in PLN24-176. Exploration drilling will start by following up on high-priority areas defined during the 2024 program based on radioactivity and geochemistry results. Due to our unique methodology of drilling by precasing drill holes with a sonic rig and the diamond drill following, the drilling sequence will be variable and go back-and-forth between zone drilling and exploration. Meanwhile, we are still waiting for assay results from 25 drill holes from the 2024 season, including both JR zone and exploration holes, and will release those as they come available. These results will also be used for the planning of further exploration drilling."

Samples from the drill core are split into half sections on site. Where possible, samples are standardized at 0.5 m 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, Sask., 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 per cent U3O8 as "high grade" and results greater than 20 weight per cent U3O8 as "ultrahigh grade."

All depth measurements reported are down hole, and true thicknesses are yet to be determined.

About F3 Uranium Corp.

F3 Uranium is a uranium exploration company, focusing on the recently discovered, high-grade JR zone on its Patterson Lake North project in the western Athabasca basin. F3 Uranium currently has three properties in the Athabasca basin: Patterson Lake North, Minto and Broach. The western side of the Athabasca basin, Saskatchewan, is home to some of the world's largest high-grade uranium deposits, including Triple R and Arrow, and poised to become the next major area of high-grade uranium operations in the world.
