20.0m Composite Mineralization at JR Zone with 2.25m high grade Radioactivity
Kelowna, British Columbia–(Newsfile Corp. – March 18, 2025) – F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) (“F3” or “the Company”) is pleased to release initial scintillometer results from the ongoing winter drill programs at the PLN and Broach Properties including drilling at JR Zone, B1, and the PW Area. At Broach Lake a new prospective area “PW” is emerging, where exploration drillhole PLN25-202 encountered six distinct zones of anomalous radioactivity, with readings ranging between 300 cps and 720 cps over a 90m downhole interval. At JR Zone, PLN25-200 returned mineralization over 20.0m, including 2.25m of high grade (>10,000 cps) containing 0.68m of off-scale mineralization (>65,535 cps).

Sam Hartmann, Vice President Exploration, commented:
“The ‘PW’ area, situated on the Broach Property approximately 12 kilometers south of the JR Zone, lies just within the Athabasca Basin and represents a region with minimal historical exploration and drilling activity. No previously defined conductors had been identified in this area, largely due to the presence of a thick layer of conductive Cretaceous mudstone from the Manville Group, which locally reaches thicknesses of nearly 100 meters. Recognizing the potential of this challenging but underexplored region, we conducted a specifically designed MLTDEM ground survey (see NR February 11) which has just been completed by Abitibi Geophysics. This approach successfully delineated a number of basement-hosted conductors on the survey lines interpreted so far with lines L3200N to L4400N still outstanding (see Map 2), overcoming the interference posed by the conductive mudstones. Drillhole PLN25-202 was collared based on an initial interpretation and conductor model on L1600N, and intersected strongly altered basement lithologies, encountering six distinct radioactive intercepts across a 90-meter downhole interval. Data from this drillhole was subsequently re-integrated back into the electromagnetic (EM) model – which resulted in a lateral shift of the conductor model by approximately 100 meters. This adjustment suggests that PLN25-202 overshot the intended target yet – still encountered significant alteration and structures along with radioactivity. A follow-up drillhole is scheduled and planned to step back by approximately 100 meters to better intersect the refined target, which lies in a distinct circular gravity anomaly. While the PW Area is still in its early stages of exploration, we are highly encouraged by these strong initial results, and intend to conduct further drilling in the area before shifting focus back to the JR Zone toward the conclusion of the winter season.”

Handheld spectrometer composite parameters:
1: Minimum Thickness of 0.5m
2: CPS Cut-Off of 300 counts per second
3: Maximum Internal Dilution of 2.0m
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. 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 with a scintillometer)—as “anomalous”, readings above 10,000 cps as “high-grade”, 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.
