F3 Hits 4.35m Off-Scale Mineralization

(>65,535 cps) at JR Zone

Kelowna, British Columbia--(Newsfile Corp. - September 10, 2024) -

F3 Uranium Corp

(TSV: FUU)

(OTCQB: FUUFF)

("

F3

" or "

the Company

") is pleased to announce scintillometer results from the

current summer drill program, including PLN24-176 which was cored in the JR Zone and which returned

mineralization over 11.0m, including 5.40m of high grade (>10,000 cps) containing

4.35m of

composite off-scale mineralization

(>65,535 cps).

Sam Hartmann, Vice President Exploration, commented:

"PLN24-176 was planned to increase confidence and high-grade continuity in the heart of the JR Zone,

approximately 15m in the up-dip direction of PLN24-137 (see NR April 1, 2024 and July 20, 2024).

Based on total radioactivity and the intercepted width of high grade, we expect this hole to rank near the

top of all drillholes at JR. Exploration remains the focus of the program; previously (see NR August 13,

2024) we announced PLN24-168, which stepped out 700m along strike and encountered the altered

and strongly graphitic B1 shear well below the Athabasca Unconformity. PLN24-175 was a follow up,

testing the same structure 110m up-dip targeting its intersection with the unconformity. This hole

intersected strong alteration in the basement; coupled with intense silicification and brecciation

observed in the lower Athabasca Sandstone and the lack of graphitic structure in the basement,

indications are that the structure dips steeper than presumed. This reveals a new target down-dip from

PLN24-175 and an additional hole is planned to test the structure in this area with these prospective

signs for nearby mineralization."

Handheld spectrometer composite parameters:

1: Minimum Thickness of 0.5m

2: CPS Cut-Off of 300 counts per second

3: Maximum Internal Dilution of 2.

0m

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. Samples from the drill core are split in

half on site and are standardized at 0.5m 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.

About Patterson Lake North:

The Company's 4,078-hectare 100% owned Patterson Lake North property (PLN) is located just within

the south-western edge of the Athabasca Basin in proximity to Fission Uranium's Triple R and NexGen

Energy's Arrow high-grade world class uranium deposits which is poised to become the next major area

of development for new uranium operations in northern Saskatchewan. PLN is accessed by Provincial

Highway 955, which transects the property, and the new JR Zone uranium discovery is located 23km

northwest of Fission Uranium's Triple R deposit.

Qualified Person:

About F3 Uranium Corp.:

F3 Uranium is a uranium exploration company advancing its newly discovered high-grade JR Zone and

exploring for additional mineralized zones on its 100%-owned Patterson Lake North (PLN) Project in the

southwest Athabasca Basin. PLN is accessed by Provincial Highway 955, which transects the property,

and the new JR Zone discovery is located ~25km northwest of Fission Uranium's Triple R and NexGen

development for new uranium operations in northern Saskatchewan. The PLN project is comprised of

the PLN, Minto and Broach properties. The Broach property incorporates the former PW property which

was obtained from CanAlaska as a result of a property swap.
