On New Trend – 12km South of JR Zone
Kelowna, British Columbia–(Newsfile Corp. – April 15, 2025) – F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) (“F3” or “the Company“) is pleased to announce a new discovery with drillhole PLN25-205 which intersected radioactivity over a total of 33.0m including 0.56m of high radioactivity (>10,000 cps) with a peak of 37,700 cps at 398.34m. The drillhole is still currently in progress, however additional mineralization is not expected.
2025 Handheld Spectrometer Highlights:
Broach Lake: PW Area
PLN25-205 (line 11310S):
- 0.5m interval with radioactivity of 340 cps between 340.0 and 340.5m, and
- 0.5m interval with radioactivity of 440 cps between 347.5 and 348.0m, and
- 0.5m interval with radioactivity of 370 cps between 366.0 and 366.5m, and
- 8.0m interval with radioactivity peaking 2,500 cps between 373.0m and 381.0m, and
- 23.5m interval with radioactivity peaking 37,700 cps between 384.0m and 407.5m, including
- 0.56m composite mineralization >10,000 cps between 389.75m and 398.56m
Sam Hartmann, Vice President Exploration, commented:
“On March 18th we announced anomalous radioactivity at a newly emerging area 12km south of the JR Zone, showing great initial potential with drillhole PLN25-202, peaking at 720cps. This was followed up with an aggressive step back with PLN25-203, which aimed to locate a MLTDEM ground conductor. Encouraging alteration was encountered at depth corresponding with the approximate down-dip projection of the radioactive intervals in PLN25-202, but no anomalous radioactivity was noted. PLN25-204 then tested 60m up-dip of PLN25-202, successfully intersecting the targeted rock units but again with no anomalous radioactivity. Despite these results we decided on one more follow-up to PLN25-202 targeting approximately 50m down-dip (see Image 1 for cross section), this time successfully intersecting high-grade pitchblende mineralization hosted within competent but strongly chloritic and clay altered orthogneisses (see Image 2), in the hanging wall of an unmineralized fault with mineralization starting at a vertical depth of 325 meters from surface. This discovery is particularly meaningful as it is within the Clearwater Domain – a geological package predominantly thought to consist of intrusive rocks and historically considered less prospective for uranium mineralization. These drillholes contain significant intercepts of dioritic rocks – but also the strained and structurally disturbed orthogneisses we target. This strong initial intercept in PLN25-205 is the perfect analog to the approach of the technical team at F3 Uranium; to think out of the box and be persistent. After we finish drilling this hole, we plan to continue drilling on section to improve our understanding of the controls on the mineralization, before moving laterally along strike, which is open in both directions”.

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 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 % 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.
