Kelowna, British Columbia--(Newsfile Corp. - November 27, 2023) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce additional assay results for the ongoing drill program, including PLN23-086 (see NR dated August 14, 2023) which returned 5.5m of 7.56 % U₃O₈, including an ultra-high grade 2.0m interval averaging 20.6% U₃O₈. At the A1B area, drill hole PLN23-093 encountered a 2.0m interval averaging 5,557 ppm Boron in highly altered Athabasca Sandstone, approximately 17m from the unconformity along the A1B shear.

Sam Hartmann, VP Exploration commented:

"In addition to high grade assay intercepts reported in the JR Zone, we are pleased to discuss our first geochemical exploration drilling results from the A1B area; drill hole PLN23-093, where intense sandstone and basement alteration was previously reported, returned a 2.0m interval with significant individual boron values between 3,000 and 10,000 ppm. Boron values over 5,000 ppm, associated with dravite veining and breccias, have previously only been intersected on the property within Athabasca Sandstone immediately above the JR Zone, 3.5 km away.

"PLN23-095, which was a deeper target intercept approximately 800m grid north of PLN23-093, previously reported anomalous radioactivity up to 300 cps within a fault system related to the A1B conductor; this returned basement hosted uranium values up to 58 ppm. To put that into context, PLN23-071 (see NR dated July 17, 2023) on line 165S returned a maximum of 51 ppm uranium in the A1 shear, 45m along strike away from high grade mineralization within the JR Zone. It is our view that in comparison to the JR Zone, the A1B system represents an area of widespread structural complexity, with evidence of significant re-activated reverse structures extending into the sandstone. With this complexity also comes opportunity and I see the A1B shear area among the most prospective places to make the next discovery, considering these first geochemistry results. Going forward we will refer to the A1B shear zone as B1 to differentiate it more clearly from the A1 shear zone, as a separate structure."

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 but the Company estimates true thickness of the reported intervals in this news release to be close to reported interval widths.
