F3 Hits 57.6% U3O8 Over 1.0m within 9.4% over 14.5m in 60m Step-out from A1 Discovery

Kelowna, British Columbia–(Newsfile Corp. – April 17, 2023) – F3 Uranium Corp (TSV: FUU) (OTCQB: FUUFF) (“F3” or “the Company“) is pleased to announce initial assay results from 12 drill holes, including drill hole PLN23-060 at Patterson Lake North (PLN) where the strongest radioactivity to date was previously reported (see Press Release March 27, 2023).

The analysis for PLN23-060 returned one continuous 14.5m interval averaging 9.4% U₃O₈including an ultra-high-grade 5.0m interval averaging 26.7% U₃O₈, which further includes a 2.5m interval which assayed 45.6% U₃O₈.

Assay results from a total of 12 drill holes from the Winter 2023 drill program are disclosed below in Table 1, including drill holes PLN23-042 through PLN23-052.

Raymond Ashley, President, commented:

“This first release of assays from the Winter 2023 program at PLN adds confidence to the previously released scintillometer results, and we are pleased to report on 12 drill holes, 8 of which contain high grade uranium mineralization. The JR Zone has now been defined over a total strike length of 105m and remains open particularly along strike to the south and at depth, and up-dip towards the Athabasca unconformity. PLN23-060, cored 60m grid south from the discovery hole intercepted truly impressive grades within the A1 main shear zone, with a peak sample grade of 65.2 % U₃O₈ over 0.5m at a downhole depth of 244.5m.”

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. All depth measurements reported are down-hole and true thickness 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. 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”.
