F3 - Extends Mineralization with 67.0m of Radioactivity at Tetra Zone Largest Radioactive Intervals to Date on Project
F3 - Extends Mineralization with 67.0m of
Radioactivity at Tetra Zone
Largest Radioactive Intervals to Date on Project
Kelowna, British Columbia--(Newsfile Corp. - August 5, 2025) -
F3 Uranium Corp
(TSXV: FUU)
(OTCQB: FUUFF)
("
F3
" or "
the Company
") is pleased to announce hand-held scintillometer results at
Tetra Zone, where the
widest intervals of radioactivity to date
on the Patterson Lake North Project
have been intersected with
PLN25-217
, which intersected a total of
67.0m composite radioactivity
between 299.5m and 414.5m, including
49.0m of continuous radioactivity
between 347.5m and
396.5m. Additionally,
PLN25-212
, approximately 23m up-dip of PLN25-217 and 31m along strike from
the discovery hole PLN25-205, intersected the second widest interval to date with
39.5m composite
radioactivity
between 330.0m and 409.5m,
including 27.5m of continuous radioactivity
between
360.5m and 396.5m.
2025 Handheld Spectrometer Highlights:
Tetra Zone
PLN25-217
(line 11280S):
0.5m interval with radioactivity between 299.5m and 300.0m, and
0.5m interval with radioactivity between 315.5m and 316.0m, and
7.5m interval
with radioactivity between 336.5m and 344.0m, and
49.0m interval
with radioactivity between 347.5m and 396.5m, and
9.0m interval
with radioactivity between 399.5m and 408.5m, and
0.5m interval with radioactivity between 414.0m and 414.5m.
PLN25-212
(line 11310S):
2.5m interval
with radioactivity between 330.0m and 332.5m, and
0.5m interval with radioactivity between 346.5m and 347.0m, and
0.5m interval with radioactivity between 354.0m and 354.5m, and
27.5m interval
with radioactivity between 360.5m and 388.0m, and
6.0m interval
with radioactivity between 394.0m and 400.0m, and
2.5m interval
with radioactivity between 407.0m and 409.5m.
Sam Hartmann, Vice President Exploration, commented:
"The substantial radioactive widths intersected in these drill holes were truly unexpected and highlight the
significant potential we see at the Tetra Zone. Despite challenging drilling conditions and the non-
traditional style of mineralization, each hole provides valuable insights into deposit model generation and
drill plan adaptations. Notably, PLN25-217 confirms a theorized strike direction deviating from the
current conductor model, and we will continue to explore this trend. To improve our conductor modeling
around the Tetra Zone area, we are planning a ground geophysical program based on a tighter grid to
support larger step-outs along the Tetra Zone, which stands to reduce the number of drill holes required
for targeting. Additionally, we cored two drill holes at the JR Zone using casings set last winter with
PLN25-215 and -216, which tested for crosscutting structures; those assays will be included in our
maiden resource estimate, expected in Q4. We are very excited and look forward to further uncovering
this unique system hosting the Tetra Zone."

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 between a spectrometer and 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.
All depth measurements reported are down-hole and true thicknesses are yet to be determined.
