Drill Results

F3 Hits 2.5m of 18.6% U3O8 within 3.2% over

15.0m at JR Zone

Kelowna, British Columbia--(Newsfile Corp. - July 30, 2024) -

F3 Uranium Corp

(TSXV: FUU)

(OTCQB: FUUFF)

("

F3

" or "

the Company

") is pleased to announce final assay results from the winter

2024 drill program, including PLN24-137 which was cored in the JR Zone (see NR April 16, 2024) and

which returned

15.0m of 3.2% U

, including a

high grade 2.5m interval averaging 18.6% U

,

further including the ultra-high grade core with

1.5m of 30.3% U

.

Exploration geochemistry for the continuing summer drill program has also been received up to hole

PLN24-152 which focused on drill testing both the A1 main shear, as well as a related fault splay termed

the "North Horse" grid south of the cross-cutting Harrison Fault, a significant structure corresponding to a

vertical offset of approximately 130m. Two radioactive intervals (see NR June 12, 2024) corresponding

to the main A1 and North Horse structures respectively yielded the strongest exploration geochemistry

results outside of JR Zone to date, with the main A1 intersect assaying

0.045% U

O

, and the North

Horse intersect assaying

0.014% U

O

over 7 meters

including

0.051% U

over 0.5m

(see Photo

A series of shorter exploration drill holes have been completed on the main A1 shear infilling gaps, and

although there are multiple areas warranting follow up, exploration drilling in the near term will focus on

the areas near Harrison Fault, and to the southeast.

Sam Hartmann, Vice President Exploration, commented:

"We are very pleased with these ongoing results. Drillhole PLN24-152 stands out with the strongest

geochemistry signatures to date outside of the JR Zone and represents one of the highest priority

exploration targets for follow up. This hole targeted the intersect of the Harrison Fault and the A1 Main

shear zone just south of the Harrison Fault. Targeting in this area now includes the Harrison Fault itself,

and the areas of shear intersections with it. We are persistent in our efforts to hone in on potential high-

grade mineralization indicated by encouraging results from our systematic drilling in this area."

Assay composite parameters:

3. Maximum Internal Dilution: 2.0 m

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.

Composited weight % U3O8 mineralized intervals are summarized in Table 1. Samples from the drill

core are split into 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 % U

3

O

8

as

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

3

O

8

as "ultra-high grade".

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:
