Sam Hartmann, Vice President Exploration Comment:
"We are pleased to release the final assays for Tetra Zone from the Fall 2025 program. PLN25-219A
returned a broad 13.0-metre interval grading 0.28% U

that includes several higher-grade sub-
intervals, totaling 4.5m of composite high-grade mineralization. These results, together with the
confirmation of continuity in PLN25-221, provide important geological information that will help refine our
understanding of the Tetra Zone's controls and geometry. A follow-up drill program is currently in
progress at the Tetra Zone utilizing one diamond drill."

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