F3 Hits 2.0m of 31.4% U3O8 Within 7.6% Over 12.0m at JR

June 12, 2024 5:00 AM EDT | Source: F3 Uranium Corp.

Kelowna, British Columbia--(Newsfile Corp. - June 12, 2024) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce assay results for fifteen drillholes from the winter 2024 drill program, including PLN24-116 which was cored in the JR Zone (see NR January 30, 2024) and which returned 12.0m of 7.6% U3O8, including a high grade 8.0m interval averaging 11.2% U3O8, further including an ultra-high grade core of 2.0m of 31.4% U3O8. The ongoing summer exploration drilling around the southern end of A1 and northern end of B1 continues to yield excellent structure with intermittent anomalous radioactivity, with PLN24-152 intercepting two distinct radioactive intercepts with up to 760 cps.

Exploration is proceeding with two diamond drills, one focused on systematically testing the A1 shear using short holes, infilling along strike in areas with low drillhole density and intercepting intermittent weak radioactivity. The second diamond drill is currently focusing on the area between the southern end of the A1 shear and the B1 shear, an area of structural complexity marked by the cross-cutting Harrison fault, with related A1 shear splays interpreted as fault horses on the footwall side of the Harrison fault. Of particular interest is PLN24-152 (see Photo 1) which intersected two radioactive intervals within graphitic and clay altered shear zones including the main A1 shear.

A large-scale ground gravity survey, including coverage over the A1 and B1 shears is still in progress.

Sam Hartmann, Vice President Exploration, commented:

"We are very pleased with the results of the ongoing exploration program, in particular the area around the southern end of A1 where our geological targeting model is improving. The area between the A1 and B1 shears continues to be rich with the right kind of structures - altered and displaying radioactivity. Our release today includes winter assays up to hole PLN24-131, with an additional fourteen holes still outstanding, including six from B1. Strongly anomalous exploration geochemistry results at B1 with up to 0.022 % U3O8 in PLN24-122 reinforce our belief that the area has the potential to host high grade uranium. This is bolstered by the concurrent release of scintillometer data including PLN24-152, which intersected two radioactive intervals - coupled with very favorable structure and alteration."

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.

Natural gamma radiation in the drill core that is reported in this news release was measured in counts per second (cps) using a handheld Radiation Solutions RS-125 scintillometer. The Company considers greater than 300 cps on the handheld spectrometer as anomalous, >10,000 cps as high grade and greater than 65,535 cps as off-scale. The reader is cautioned that scintillometer readings are not directly or uniformly related to uranium grades of the rock sample measured and should be used only as a preliminary indication of the presence of radioactive materials.

Composited weight % U3O8 mineralized intervals are summarized in Table 1. 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 thickness are yet to be determined.
