F3 Hits More Anomalous Radioactivity on A1B Shear 3.4km South of JR Zone

Kelowna, British Columbia--(Newsfile Corp. - October 16, 2023) - F3 Uranium Corp. (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce results from five holes of the ongoing extended fall drill program on the Patterson Lake North ("PLN") Property, including PLN23-102 located 3.4km south of the JR Zone which is now the second hole to intersect anomalous radioactivity along the recently discovered and highly prospective A1B Shear Zone ("A1B"). Hole PLN23-102 was drilled 840m along strike to the south of PLN23-095 which was the first hole to hit anomalous radioactivity at A1B, which runs parallel to the A1 Main Shear Zone that hosts the JR Zone (see NR dated September 14, 2023).

Concurrently at the JR Zone, PLN23-101 has intersected mineralization over a 10.50m interval, including 1.42m of high grade (>10,000 cps), of which 0.50m was up to 54,400 cps radioactivity between 228.50 and 229.00m, extending mineralization up dip on line 015S from PLN23-044 (see NR dated April 17, 2023).

Raymond Ashley, President, commented:

"Drill hole PLN23-102 at A1B exhibited very intense alteration and dissolution of the sandstone together with 96m of core loss over a 162m interval, followed by extreme basement alteration including bleaching and clay alteration (see Photo 1 below). These features, in addition to anomalous radioactivity in 2 holes located 840 meters apart along strike, are characteristic of favourable conditions for the discovery of proximal mineralization. The team continues to be excited about the potential for discovery of a second mineralized zone on A1B."

"We have one drill focused at the JR Zone and a second drill focused on exploration drilling to characterize targets for 2024. The pace of drilling has slowed as we are drilling deeper exploration holes to learn more about the parallel A1B shear zone; we want to be methodical in characterizing areas for drilling in 2024 and are now using a single diamond drill crew who move between the two drills. This understanding will be integrated with the results of ground geophysics to be carried out later this fall and in the early winter, to develop the best drill targets possible for 2024. The Company is fully funded to continue its aggressive exploration approach."

JR Zone Drilling Highlights:

PLN23-101 (line 015S)

  • 10.50m composite mineralization from 216.50m - 230.50m, including
    • 1.42m composite mineralization of >10,000 cps radioactivity between 222.85m - 229.00m including 0.50m radioactivity up to 54,400 cps between 228.50m and 229.00m

Exploration Drilling Highlights:

PLN23-102 (line 3450S), A1B Shear Zone

  • 96.00m cumulative core loss in Athabasca sandstone between 176.00m and 338.00m
    • Indicative of large-scale sandstone dissolution due to intense alteration above the A1B shear zone
  • 0.50m radioactivity of 1,000 cps from 411.50m to 412.00m
    • Second occurrence of anomalous radioactivity, within the main A1B shear zone

Handheld spectrometer composite parameters:
1: Minimum Thickness of 0.5m
2: CPS Cut-Off of 300 counts per second
3: Maximum Internal Dilution of 2.

Natural gamma radiation in the drill core that is reported in this news release was measured in counts per second (cps) using a handheld Radiation Solutions RS-125 scintillometer. The Company considers greater than 300 cps on the handheld spectrometer as anomalous, >10,000 cps as high-grade and greater than 65,535 cps as off-scale. The reader is cautioned that scintillometer readings are not directly or uniformly related to uranium grades of the rock sample measured and should be used only as a preliminary indication of the presence of radioactive materials.

All depth measurements reported are down-hole and true thicknesses are yet to be determined, but the Company estimates true thickness of the reported intervals in this news release to be close to reported interval widths.
