F3 More Than Doubles Tetra Zone Length to 135m
F3 More Than Doubles Tetra Zone Length to
135m
Kelowna, British Columbia--(Newsfile Corp. - January 13, 2026) -
F3 Uranium Corp
(TSXV: FUU)
(OTCQB: FUUFF)
("
F3
" or "
the Company
") is pleased to announce final scintillometer results from its
2025 fall drill program on the Tetra Zone on the Broach Property. The program consisted of five diamond
drill holes totaling 2,628m and
extended the interpreted mineralized plunge length
from
60m to
135m, an increase of 125%.
Sam Hartmann, Vice President Exploration, commented:
"The fall 2025 program was designed to test the plunge continuity of uranium mineralization in the Tetra
Zone shear. Drilling extended the known mineralized plunge length from 60m to 135m. On the down-
plunge (western) side, holes PLN25-220A and PLN25-220AW1 tested continuity but appear to have
intersected the structure just above the expected mineralized zone, with radioactivity and broader
shearing observed in PLN25-220A. On the up-plunge (eastern) side, PLN25-221 confirmed continuity,
stepping out approximately 28m from PLN25-205 (see news release, July 16, 2025). The roughly 300m
of shear zone remaining in the up-plunge direction toward the Athabasca Unconformity, along with the
down-plunge extent, represent first order priority areas for follow-up drilling, which we are planning to
start later this month. Assays from the fall program, including PLN25-217, which intersected
mineralization over a total of 29.5m, 27.5m of which is continuous and includes 2.30m of >10,000 cps
between 396.70m and 407.30m, are currently at SRC and will be released as they become available."
Fall 2025 Handheld Spectrometer Highlights:
Tetra Zone
PLN25-221
(line 11310S):
2.0m radioactivity between 333.5m and 335.5m, and
8.5m radioactivity between 338.0m and 346.5m with a peak of 4,500 cps, and
0.5m radioactivity between 351.0m and 351.5m

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 terminology; this 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.
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.
