F3 HITS 16.1% U3O8 OVER 3.0M WITHIN 4.6% OVER 12.5M IN 75M STEP-OUT FROM A1 DISCOVERY

F3 Uranium Corp. has released final results from the nine remaining drill holes of the 21-hole winter 2023 program, including drill hole PLN23-061, drilled at the JR zone on the Patterson Lake North (PLN) property. The analysis for PLN23-061, cored 75m grid south from the discovery hole, returned one continuous 12.5m interval averaging 4.6 per cent U3O8, including a high-grade 5.0m interval averaging 10.9 per cent U3O8, which further includes a 3.0m interval which assayed 16.1 per cent U3O8.

Planning is in progress for a $12M summer exploration program, scheduled to commence early June, to continue JR Zone expansion, in addition to exploration along the A1 Main Shear Zone where previous drilling in 2014 and 2019 intersected the same structure as what is interpreted to be hosting the JR Zone. The work permits for the program have been received from the Saskatchewan Ministry of Environment.

Final assay results from 7 mineralized drill holes are disclosed below in Table 1, including drill holes PLN23-053 through PLN23-059, and drill holes PLN23-061 and PLN23-062.

Raymond Ashley, President, commented:

"This final release of assays from the Winter 2023 program at PLN confirms the previously reported scintillometer results that drill holes PLN23-061 and PLN23-062 that were cored furthest to the south from the discovery hole, 75m and 90m respectively, intersected the ultra-high-grade core with individual samples returning in excess of 20.0 per cent U3O8. The JR Zone has now been defined over a total strike length of 105 meters and the upcoming summer program will aim to extend the zone in particular to the south, where assays from drill holes PLN23-060, 061 and 062 have shown that mineralization continues along strike, and up-dip towards the Athabasca Unconformity.

Assay composite parameters:

1: Minimum Thickness of 0.5 m2: Assay Grade Cut-Off: 0.05 per cent U3O8 (weight per cent)3. Maximum Internal Dilution: 2.0 m

Composited weight per cent 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 per cent U3O8 as "high grade" and results greater than 20.0 weight per cent U3O8 as "ultra-high grade".
