F3 Expands B1 Shear by 80% with 700m Step-

Out Hole

Hits 0.71m of Off-Scale (>65,535cps) within 12.0m of

Mineralization at JR

Kelowna, British Columbia--(Newsfile Corp. - August 13, 2024) -

F3 Uranium Corp

(TSXV: FUU)

(OTCQB: FUUFF)

("

F3

" or "

the Company

") is pleased to announce recent JR Zone high grade infill

summer drilling highlighted by PLN24-161, which intersected mineralization over 12.0m, including 2.0m

of high grade (>10,000cps) also hosting

0.71m of composite off-scale mineralization

(>65,535 cps).

Drill hole PLN24-163 at JR intersected

0.90m of composite high grade mineralization (>10,000

cps)

within

20.5m of mineralization (>300cps).

JR Zone infill holes targeted areas of low drill hole

density within the high-grade core of the zone. These holes help to improve and define the continuity of

grade within the JR Zone.

F3 engaged Computational Geosciences to provide new geologically constrained inversions of ground

loop time domain electromagnetic (GTEM) and direct current (DC) resistivity data already collected on

the ground. These parametric models of electric conductivity (see Figure 1) defined a clear extension of

the B1 trend which was tested and validated with drillhole PLN24-168, a 700m step-out along strike from

PLN24-126, which was the most southeasterly hole along the B1 shear zone previously and 1,300m from

its northwest end. Drill hole PLN24-168 intersected a 14.2m strongly prospective and wide clay altered

graphitic shear zone approximately 110m below the Athabasca Unconformity in the down-dip direction

(see Photo 1). Additionally, the inversion indicated the B1 conductor trend to continue to the southeast

an additional 700m to the edge of the survey block resulting in an approximate 80% increase in the total

implied strike length of the B1 shear zone to 2.7km.

Sam Hartmann, Vice President Exploration, commented:

"PLN24-168 was collared on line 4245S, approximately 1.2 km along strike from the Harrison Fault and

PLN24-152 area, opening up an additional 700m of prospective strike from previous drilling. This

wildcat hole was collared conservatively, testing the newly defined conductive feature well below the

Athabasca Unconformity; an altered and strongly graphitic shear representing the continuation of B1 was

intersected as predicted from the conductivity model; it also exhibited elevated radioactivity averaging

200 cps peaking up to 240cps; although that doesn't quite meet our reporting threshold of 300 cps, it

adds to the prospectivity and follow-up holes are now being planned for that area. Geochemistry results

from this ongoing drill program are being integrated into our models and drill plans as they arrive which

is assisting us with targeting with greater confidence."

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.

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:

The technical information in this news release has been prepare in accordance with the Canadian

regulatory requirements set out in National Instrument 43-101 and approved on behalf of the company by

Raymond Ashley, P.Geo., President & COO of F3 Uranium Corp, a Qualified Person. Mr. Ashley has

verified the data disclosed.

About F3 Uranium Corp.:

F3 Uranium is a uranium project generator and exploration company, focusing on projects in the

Athabasca Basin, home to some of the world's largest high grade uranium discovery. F3 Uranium

currently has 20 projects in the Athabasca Basin. Several of F3's projects are near large uranium

discoveries including Triple R, Arrow and Hurricane. F3 has announced a transaction pursuant to which it

will transfer 17 of its prospective uranium exploration properties to F4 in exchange for common shares of

F4 which will be distributed to F3 shareholders on the basis of one F4 Share for every common share of

F3 held; the F4 shares will then be rolled back at a rate of 10 to 1. F3 will retain the PLN Project

consisting of the PLN, Misto and Broach properties. The Broach property incorporates the PW property

which it obtained from CanAlaska as the result of a property swap.
