F3 Uranium Hits >65535 CPS in 30m Stepout and Expands JR Zone North and South

This news release is not for distribution to U.S. newswire services for dissemination in the United States.

Kelowna, BC – February 8, 2023 – F3 Uranium Corp. (“F3 Uranium” or the “Company”) (TSXV: FUU – OTCQB: FUUF – FRA:2F3A) is pleased to announce results from the first eight drill holes of the 20-hole winter drill program at the JR Zone on the Patterson Lake North (“PLN”) Property. Most significantly, continuity of high grade mineralization has been established along strike towards the south with hole PLN23-048 on line 030S, which hit 14.0m total composite mineralization with 4.0m of >40,000 cps, including 0.5m of “offscale” or >65,535 cps, a 30m stepout from the discovery hole. Out of the eight reported drill holes, seven are mineralized and five have high grade mineralization with radioactivity >10,000 cps.

Mineralization was further defined on section 00N up dip and towards the Athabasca Unconformity of hole PLN22-041 (see news release Feb 6, 2023) with hole PLN23-047

Raymond Ashley, Vice President Exploration, commented:

“The drill program started by testing the depth extent of the zone, while also testing it along strike from the discovery area on line 00N. The team is becoming familiar with the geology and controls on mineralization on the JR Zone which is currently defined over an area measuring approximately 45m by 50m and have identified strong continuity of high grade mineralization along strike towards the south as the program continues to explore that direction to increase the total mineralized strike length. Additionally, we are continuing to drill test further towards the unconformity, with the objective to test the intersection of the A1 main shear zone at the unconformity.”

Drilling Highlight:

PLN23-048 (line 30S):

- 14.0m total composite mineralization from 246.5m – 260.5m, including

4.0m mineralization of >40,000 cps radioactivity from 249.0m – 253.0 m with 0.5m of >65,535 cps from 252.0m – 252.5 m

Main Intercepts:

PLN23-044 (line 015S):

- 6.0m total composite mineralization over a 10.m section from 226.0m – 236.0m, including

0.5m mineralization of >10,000 cps radioactivity

PLN23-046 (line 015S):

- 3.5m mineralization from 261.5m – 265.0m, including

0.77m mineralization of >10,000 cps radioactivity

PLN23-047 (line 00N):

- 7.5m total composite mineralization over a 10.5m section from 199.0m – 209.5m, including

1.1m total composite mineralization of >10,000 cps radioactivity

PLN23-049 (line 015N):

- 7.5m mineralization from 245.0m – 252.5m, including

0.2m mineralization of >10,000 cps radioactivity

Mineralization remains open in all directions.

Natural gamma radiation in the drill core that is reported in this news release was measured in counts per second (cps) using a handheld Radiation Solutions RS-125 scintillometer. The Company considers greater than 300 cps on the handheld spectrometer as anomalous, >10,000 cps as high grade and greater than 65,535 cps as off-scale. The reader is cautioned that scintillometer readings are not directly or uniformly related to uranium grades of the rock sample measured and should be used only as a preliminary indication of the presence of radioactive materials. All depth measurements reported are down-hole and true thickness are yet to be determined. Samples from the drill core are split in half on site and are standardized at 0.5 m lengths. One half of the split sample will be submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK. for lithogeochemical analysis using their "Uranium Package".

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.
