F3 Intersects Radioactivity Across Multiple

Zones

Uncovers Significant and Favorable Reverse Faulting at B1

Kelowna, British Columbia--(Newsfile Corp. - April 16, 2024) -

F3 Uranium Corp

(TSV: FUU)

(OTCQB: FUUFF)

("

F3

" or "

the Company

") is pleased to announce the completion of the first 30 drill

holes (totaling 12,100 meters) of its 2024 winter drill program. JR Zone has continued to yield high grade

intercepts, such as PLN23-137 which intersected mineralization within a 18.5m interval including

1.25m

of composite off-scale mineralization

(>65,535 cps),

while the Company's focus has expanded to

the discovery of additional mineralized zones along the A1 and B1 structures, with

numerous

radioactive intercepts

along both shears, generating additional drill targets.

Ray Ashley, President, commented: "We are very pleased with the results from this winter's drill

program, and the number of new targets generated along both the A1 and B1 systems. The scale of

reverse faulting in conjunction with related massive graphitic fault structures at B1 was unexpected and

supports our theory that the majority of B1 drilling south of line 2850 may have been in the footwall of this

fault, where intense alteration and frequent radioactive intercepts suggest the presence of a nearby

source. At A1, considerable undrilled gaps remain open for exploration, such as the 800m gap where

hole PLN24-140 was drilled, returning over 11,000 cps on the gamma probe within the shear. With a

large-scale gravity survey underway, in addition to a joint inversion of ground EM and resistivity

geophysics, we continue to develop new targets for the drill program slated to resume in May after a

short pause for seasonal breakup."

A1 Shear Zone

A1, which is host to the high-grade JR Zone, contains several significant undrilled sections: PLN24-140

was collared on line 2325S, within a 800m long area along the A1 with no previous drilling, and

intersected up to 560 cps on the handheld spectrometer, and up to 11,000 cps on the QL40 GRA

gamma probe. Prior to PLN24-140, gamma probe readings greater than 10,000 cps had not been

encountered outside of the JR Zone, resulting in a priority target for the program resumption in May.

B1 Shear Zone

At B1, a total of nine drill holes targeted the intense alteration and structure intersected during the 2023

drill campaign, as these features often occur in close proximity to high grade uranium mineralization.

Five drill holes intersected anomalous radiation over a total strike length of 600m.

Drill hole PLN24-133

targeted an area near the northern end of the B1 shear zone where a significant change in Athabasca

Sandstone depth was expected and encountered a basement wedge in excess of 120m downhole

thickness within the sandstone exhibiting strong alteration and deformation (see Cross Section for line

2850S below). Figure 1 shows the lower structural Athabasca Unconformity at a depth of 291.2m, with

significantly structurally disturbed sandstone beneath. An extremely graphitic structure was intersected

within this wedge (see Figure 2), and in all follow up drilling on section and along strike. Drilling on line

2850S with PLN24-138 and PLN24-142 and step out drilling on line 2820S with PLN24-144 confirmed

that the strike of this very significant offsetting reverse structure appears to be discordant to the B1 main

shear, and likely related to the Harrison fault, a significant regional structure which played an important

role in the development of the Athabasca basin.

This magnitude of displacement along wide and strongly graphitic basement faults is highly favorable,

and structurally comparable to what is seen at some of the largest uranium deposits in the basin. This

now provides a number of drill targets for high grade uranium mineralization including the unconformity

contacts, as well as the basement "nose" at the terminus of the wedge within the sandstone, with a focus

on where the A1 and B1 structures intercept this offsetting reverse fault.

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 thicknesses are yet to be determined.

The Company contracted Patterson Geophysics Inc. ("

Patterson

") to complete 65 line-km of fixed loop

SQUID electromagnetic survey coverage (FL-SQUID-EM) over the B1 target area, to measure the

induced electromagnetic ("

EM

") fields associated with sandstone alteration effects as well as the

response to dipping basement conductors. A trace of this conductor model projected to surface is

shown on Map 1, and notably deviated in strike from the original B1 conductor model. The data collected

by Patterson was used to target and successfully drill the large graphitic structure associated with the

basement wedge intersected in PLN24-133.

Dias Geophysical Ltd. completed the 3D DC resistivity and induced polarization (DCIP) over the

northern A1 area hosting the JR Zone, and the B1 area, using their DIAS32 system. F3 has engaged a

contractor to process and perform 3D inversion modeling of resistivity and EM geophysical data jointly

and in conjunction with all the drilling data to better resolve thin basement hosted conductors.

Initial Exploration Services Inc. has been contracted to conduct a ground gravity survey over the

southwest section of the PLN and Broach properties. The survey is currently focusing on surveying the

lakes and waterbodies using ice cover, with the remainder of the survey area to be infilled in late spring,

and F3 aims to disclose those results once all the data has been collected and interpreted.

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. The PLN property is part of the PLN Project which also

includes the Minto and Broach properties.
