F3 Hits 18.0m of 8.8% U3O8 and Discovers Another Shear Zone Parallel to A1

Critical Minerals & Rare Earths, Energy, Oil & Gas + Uranium

August 14, 2023 (Source) – F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) (“F3” or “the Company“) is pleased to announce expedited assay results for PLN23-068 (see NR July 17, 2023) which returned 18.0m of 8.8% U3O8, including a high grade 11.5m interval averaging 13.7% U3O8, further including an ultra-high grade core of 4.5m of 30.1% U3O8. Significant mineralization over a 17.0m interval was intersected in PLN23-079 on line 045S, including 3.0m off-scale radioactivity (>65,535 cps) between 235.50 -239.00, of which 2.50m is continuous.

Drillhole PLN23-078 targeted the A1B EM conductor, which is parallel and laterally offset by approximately 350m to the A1 Main Shear Zone and starts approximately 2.3km grid south of the JR Zone; interpreted to be part of the JR structural system, this 1,100m long geophysical feature was drill tested for the first time and corresponded to a 15.6m wide graphitic and sulphide rich shear zone. Although there was no anomalous radioactivity associated with the single intercept, the structure itself has enough similarities with the A1 main shear zone to warrant follow up drill testing and was coined the A1B shear zone.

JR Zone drilling, as well as exploration drilling continues with two diamond drills and one sonic drill; advances with sonic casing efficiencies have allowed the program to operate with one sonic drill versus the originally budgeted two; these savings are significant enough to add additional drilling to the summer program within the originally planned summer budget and F3 now projects to drill up to 40 holes totaling 16,000m.

Sam Hartmann, Vice President Exploration, commented:

“These first assay results of the season didn’t disappoint, with PLN23-068 from line 60S yielding the best grade thickness intercept at the JR Zone to date, as was indicated from the initial scintillometer results. PLN23-079 stepped out along strike of this hole on line 45S and intersected significant off-scale mineralization. Chasing that further up-dip with PLN23-086 resulted in 23.5m of mineralization – the widest interval intersected to date – and starting at just 6m below the unconformity, which still remains un-tested. Maiden exploration drilling of the A1B EM conductor resulted in the discovery of a parallel shear zone sharing many of the hallmarks that identify the A1 main shear zone. This may indicate the JR structural system to be a more complex package than we initially thought. The potential for the A1B shear to host uranium mineralization is too great to remain untested, and we plan for additional drilling along it; in particular towards the southern end where the conductivity appears to drop off, similar to the northern end of the A1 conductor where the JR Zone is located. Fortunately, we were also able to increase our planned summer meterage due to field cost savings.”

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

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 in 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 but the Company estimates true thickness of the reported intervals in this news release to be close to reported interval widths.
