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% U

including

an ultra-high-grade 5.0m interval averaging 26.7% U

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 % U

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 % U

as "high grade" and results greater than 20.0 weight % U
