Radioactivity - 15m Step-Out at Tetra
Kelowna, British Columbia--(Newsfile Corp. - November 10, 2025) -
F3 Uranium Corp
(TSXV: FUU)
(OTCQB: FUUFF)
("
F3
" or "
the Company
") is pleased to announce initial scintillometer results from its
ongoing drill program on the Tetra Zone on the Broach Property, including a
highly radioactive
intercept in PLN25-219A
which tested for mineralization in the down plunge direction of PLN25-217
(see NR August 5, 2025) and
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.
Sam Hartmann, Vice President Exploration, commented:
"This fall drill program is intended to confirm the orientation of the shears hosting the Tetra Zone. These
initial drill intercepts validate a plunge direction of the uranium mineralization to the northwest, with
PLN25-219A successfully intercepting
15m down-plunge from PLN25-217
. In terms of radioactivity,
this is the
strongest result to date at Tetra
— very strong radioactivity up to
30,500 cps
was hosted in
the same altered and sheared gneissic units, exhibiting the usual Tetra Zone alteration features including
strong clay, hematite, sericite and bleaching (Image 3). Graphite and sulphides remain totally absent in
this system, correlating with the very weak conductive response from ground EM surveys. We will
continue drilling this system in both directions — up-plunge and down-plunge. PLN25-218 experienced
excessive dip and azimuth deviation and did not intersect the target zone. We are also providing a long-
section along the plunge direction, to help visualize these results, please see (Images 2&3) along with
the plan map."

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.

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, F3's newest discovery 13km south of the JR Zone. All three properties
comprising the PLN Project are accessed by Provincial Highway 955.

About F3 Uranium Corp.:
F3 is a uranium exploration company, focusing on the high-grade JR Zone and new Tetra Zone
discovery 13km to the south in the PW area on its Patterson Lake North (PLN) Project in the Western
Athabasca Basin. F3 currently has 3 properties in the Athabasca Basin: Patterson Lake North, Minto,
and Broach. The western side of the Athabasca Basin, Saskatchewan, is home to some of the world's
largest high grade uranium deposits including Paladin's Triple R project and NexGen's Arrow project.
