Kelowna, British Columbia--(Newsfile Corp. - December 15, 2025) -
F3 Uranium Corp. (TSXV: FUU)
(OTCQB: FUUFF)
("
F3
" or "
the Company
") is pleased to announce final assay results of the 2025 JR
Zone drill program on the PLN Property including PLN25-200 (See NR March 18, 2025) which returned
8.5m of 3.4% U
3
O
8
, including a high grade core with
2.5m of 10.2% U
3
O
8
. At the Tetra Zone, assays
confirm the presence of high grade uranium mineralization 55m along strike from discovery hole PLN25-
205 with PLN25-217 returning a
0.5m high grade interval with 1.04% U
3
O
8
within a
3.50m
mineralized interval averaging 0.30% U
3
O
8
from 400.0m to 403.5m. Total composite mineralization
of
26.5m was intersected between 340.5 to 406.5m
.
Exploration focused mainly on the area around Tetra Zone with PLN25-207 intersecting
0.06% U
3
O
8
between 621.0 to 621.5m. This deep intersect is interpreted to be associated with the same shear
system which hosts the Tetra Zone over 200m to the west.
Sam Hartmann, Vice President Exploration, Comment:
"We are pleased to release the final assays for JR Zone, where the last two holes for inclusion into the
upcoming maiden resource estimate were completed earlier this spring. At the Tetra Zone, we are
releasing the second batch of assays since the initial high grade discovery hole (PLN25-205) assays,
including an interval with high grade mineralization with 1.04% over 0.5m, confirmation of additional high-
grade uranium mineralization at the Tetra Zone, 55m along strike from the discovery hole. Exploration
geochemistry around the Tetra Zone continues to return strongly anomalous uranium values with 0.06%
U
3
O
8
at depth in PLN25-217, approximately 200m away from Tetra Zone highlighting the prospectivity
and size potential of the mineralized system."

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 % U3O8 as
"high grade" and results greater than 20.0 weight % U3O8 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 44,613-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 20,675-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.
Qualified Person:
The technical information in this news release has been prepared in accordance with the Canadian
regulatory requirements set out in National Instrument 43-101 and approved on behalf of the company by

This news release may refer to neighboring properties in which F3 Uranium has no interest, and the
Qualified Person has been unable to verify the information from those properties. Mineralization on those
neighboring properties is not necessarily indicative of mineralization on the PLN Project. For additional
information on the PLN Project, please refer to the report titled "Technical Report on the Patterson Lake
North Project, Northern Saskatchewan, Canada" prepared by SLR International Corporation with a
signing date of January 25, 2023and an effective date of November 20, 2023 available at

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.
