F3 - Hits Radioactivity in 32m Step Out -
Extending Zone at Broach Lake
Mobilizes Sonic Drill to Tetra Zone
Kelowna, British Columbia--(Newsfile Corp. - June 24, 2025) -
F3 Uranium Corp
.
(TSXV: FUU)
(OTCQB: FUUFF)
("
F3
" or "
the Company
") is pleased to announce strike growth of the radioactivity at
the PW Area on the Broach Property — now named the Tetra Zone with PLN25-210 which intersected a
total of
21.0m composite radioactivity
in a
32m step-out
along strike to the northwest from discovery
hole PLN25-205 which intersected radioactivity over a total of 33.0m including 0.56m of high
radioactivity (>10,000 cps) with a peak of 37,700 cps at 398.34m (see NR April 15, 2025). The Tetra
Zone remains open in both directions and drilling is continuing.
Geophysical and structural modeling of the Tetra Zone is advancing, and F3 is now mobilizing an LS600
Sonic drill to the Zone; this will improve the pace of overburden casing and increase targeting accuracy
— a technique deployed successfully at the JR Zone during delineation drilling.
2025 Handheld Spectrometer Highlights:
Broach Lake: Tetra Zone
PLN25-210 (line 11280S):
0.5m interval with radioactivity of 700 cps between 165.0 and 165.5m, and
0.5m interval with radioactivity of 450 cps between 308.0 and 308.5m, and
0.5m interval with radioactivity of 690 cps between 332.0 and 332.5m, and
2.0m interval with radioactivity of 340 cps between 349.0 and 351.0m, and
3.0m interval with radioactivity of 1,500 cps between 354.5 and 357.5m, and
0.5m interval with radioactivity of 920 cps between 364.0 and 364.5m, and
3.5m interval with radioactivity of 900 cps between 367.5 and 371.0m, and
3.5m interval with radioactivity of 1,200 cps between 380.0 and 383.5m, and
7.0m interval with radioactivity of 2,600 cps between 388.5 and 395.5m
Sam Hartmann, Vice President Exploration, commented:
"Bringing a Sonic drill back to site will allow us to more efficiently define, delineate and expand the highly
radioactive core seen in PLN25-205. PLN25-210 represents a 32m step out grid west and validated our
geological and structural models, which will be used for further along strike drilling. The sonic drill will
help reduce drill trace deviation as seen in PLN25-207 and allow for intersection of the target areas
exactly where intended. Assays from the discovery hole PLN25-205 are being rushed and the results will
be released once complete and reviewed. Overall, we are very encouraged by the geology in these
initial drill holes at Tetra, which is currently the best exploration target in the F3 portfolio."

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
The natural gamma radiation detected in the drill core, as detailed in this news release, was measured
in counts per second (cps) using a handheld Radiation Solutions RS-125 spectrometer which has been
calibrated by Radiation Solutions Inc. The Company designates readings exceeding 300 cps on the
handheld spectrometer (occasionally referred to as a scintillometer in industry parlance; this colloquial
usage stems from historical naming conventions and the shared functionality of detecting gamma
radiation a scintillometer)-as "anomalous", readings above 10,000 cps as "highly radioactive", and
readings surpassing 65,535 cps as "off-scale". However, readers are cautioned that spectrometer or
scintillometer measurements often do not directly or consistently correlate with the uranium grades of the
rock samples and should be regarded solely as a preliminary indicator of the presence of radioactive
materials.
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 thicknesses are yet to be determined.
About the Patterson Lake North Project:
The Company's 42,961-hectare 100% owned Patterson Lake North Project (PLN) is located just within
the south-western edge of the Athabasca Basin in proximity to Paladin's Triple R and NexGen Energy's
Arrow high-grade uranium deposits, an area poised to become the next major area of development for
new uranium operations in northern Saskatchewan. The PLN Project consists of the 4,074-hectare
Patterson Lake North Property hosting the JR Zone Uranium discovery approximately 23km northwest of
Paladin's Triple R deposit, the 19,864-hectare Minto Property, and the 19,022-hectare Broach Property
hosting the Tetra Zone, F4's newest discovery 13km south of the JR Zone. All three properties
comprising the PLN Project are accessed by Provincial Highway 955.
