Kelowna, British Columbia--(Newsfile Corp. - July 17, 2023) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUF) ("F3" or "the Company") is pleased to announce scintillometer results from four holes of the ongoing 30-hole summer drill program at the JR Zone on the Patterson Lake North ("PLN") Property, including 2 high grade intercepts in mineralized intervals that are both within 11m of the Athabasca Unconformity. Drill hole PLN23-073 tested for mineralization 15 meters up-dip of the high grade intercept reported in PLN23-068 on line 060S (see NR July 4, 2023) and intersected mineralization over an 11.5m interval starting 8m below the unconformity, including 0.70m of high grade (>10,000 cps), of which 0.50m was off-scale radioactivity (>65,535 cps) between 225.00m and 225.50m. Drill hole PLN23-074 on line 075S intersected 15.0m of mineralization starting 11m below the unconformity, including 0.20m of high grade (>10,000 cps) between 228.15 and 228.35m.
Raymond Ashley, President, commented:
"We are excited that basement mineralization has been intersected even closer to the Athabasca Unconformity, now within 8m, as this reinforces the potential for an unconformity or sandstone component to the JR Zone mineralization. The discovery of mineralization at the unconformity or in the sandstone would provide a compelling new target for JR Zone expansion drilling. Tests up dip from the JR Zone mineralization are ongoing to define the best possible target at the unconformity for this drill program. The Shea Creek deposit 46km to the north of PLN and the Key Lake deposit on the east side of the basin are examples where basement hosted uranium mineralization extends through the unconformity and into the sandstone. The first step out hole on line 165S did not intersect mineralization but additional drill holes are being planned on that section to continue to expand the footprint along strike of the JR Zone basement mineralization. In addition, exploration drilling along the A1 main shear zone has commenced, and prospective targets will be tested."
Drilling Highlights:
PLN23-073 (line 060S):
- 11.5m mineralization from 215.5m - 232.0m, including
- 0.70m mineralization of >10,000 cps radioactivity between 225.00m - 225.70m including 0.50m off-scale radioactivity (> 65,535 cps) between 225.00m and 225.50m
PLN23-074 (line 075S):
- 15.0m mineralization from 225.0m - 240.0m, including
- 0.20m of mineralization >10,000 cps between 228.15 and 228.35m
Drilling Intercepts:
PLN23-071 (line 165S):
- No mineralization >300 cps
PLN23-072 (line 690S): Exploration Hole
- No mineralization >300 cps
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. Samples from the drill core are split in half on site and are standardized at 0.5m lengths. One half of the split sample will be submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK. for lithogeochemical analysis using their "Uranium Package".
All depth measurements reported are down-hole and true thickness are yet to be determined but the Company estimates true thickness of the reported intervals in this news release to be close to reported interval widths.
