F3 Hits 66.8% U3O8 over 0.5m within 42.4% over 2.0m at JR

Kelowna, British Columbia--(Newsfile Corp. - February 12, 2024) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce final assay results from the fall 2023 drill program, including PLN23-110 (see NR dated December 18, 2023) which returned 2.0m of 42.4% U3O8 from 226.0m to 228.0m, including 1.5m averaging 55.4% U3O8 with a highest grade of 66.8% U3O8 in a single 0.5m sample. PLN23-112, drilled from line 060S returned 11.5m averaging 2.00% U3O8 from 229.0m to 240.5m including 3.5m averaging 4.24% U3O8.

Sam Hartmann, VP Exploration, commented:

"PLN23-110 returned ultra-high grade assays, including the highest assay to date - 66.8% U3O8 on section 015S, which remains open in the up-dip direction. At the B1 area, where we initially targeted the B1 EM conductor, significant alteration in sandstone and basement rocks was encountered (see NR dated December 18, 2023) and we are pleased to receive final geochemistry supporting our decision to drill a wide fence with 4 drill holes across approximately 250m of geology. Anomalous basement uranium values were intersected, notably in PLN23-105 with up to 137 ppm uranium; values of greater than 100 ppm uranium have previously only been encountered in PLN14-019 and immediately surrounding holes, as well as within the JR Zone itself."

The Company is also pleased to announce that it has completed a technical report for its Patterson Lake North (PLN) Project, including the PLN, Broach and Minto properties, pursuant to National Instrument 43-101 "Standards of Disclosure for Mineral Projects" ("NI 43-101"). The report was completed by lead consultant SLR International Corporation ("SLR") with an effective date of November 20, 2023, prepared for F3 Uranium Corp. and dated January 25, 2024. The report will be filed on SEDAR within 45 days.

Assay composite parameters:

  1. Minimum Thickness of 0.5 m
  2. Assay Grade Cut-Off: 0.05% U3O8 (weight %)
  3. Maximum Internal Dilution: 2.0 m

Composited weight % U3O8 mineralized intervals are summarized in Table 1. Samples from the drill core are split in 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 thickness are yet to be determined.
