F3 Intersects Radioactivity Across Multiple Zones

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

Uncovers Significant and Favorable Reverse Faulting at B1

April 16, 2024 (Source) — F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) (“F3” or “the Company“) is pleased to announce the completion of the first 30 drill holes (totaling 12,100 meters) of its 2024 winter drill program. JR Zone has continued to yield high grade intercepts, such as PLN23-137 which intersected mineralization within a 18.5m interval including 1.25m of composite off-scale mineralization (>65,535 cps), while the Company’s focus has expanded to the discovery of additional mineralized zones along the A1 and B1 structures, with numerous radioactive intercepts along both shears, generating additional drill targets.

Ray Ashley, President, commented: “We are very pleased with the results from this winter’s drill program, and the number of new targets generated along both the A1 and B1 systems. The scale of reverse faulting in conjunction with related massive graphitic fault structures at B1 was unexpected and supports our theory that the majority of B1 drilling south of line 2850 may have been in the footwall of this fault, where intense alteration and frequent radioactive intercepts suggest the presence of a nearby source. At A1, considerable undrilled gaps remain open for exploration, such as the 800m gap where hole PLN24-140 was drilled, returning over 11,000 cps on the gamma probe within the shear. With a large-scale gravity survey underway, in addition to a joint inversion of ground EM and resistivity geophysics, we continue to develop new targets for the drill program slated to resume in May after a short pause for seasonal breakup.”

A1 Shear Zone

A1, which is host to the high-grade JR Zone, contains several significant undrilled sections: PLN24-140 was collared on line 2325S, within a 800m long area along the A1 with no previous drilling, and intersected up to 560 cps on the handheld spectrometer, and up to 11,000 cps on the QL40 GRA gamma probe. Prior to PLN24-140, gamma probe readings greater than 10,000 cps had not been encountered outside of the JR Zone, resulting in a priority target for the program resumption in May.

B1 Shear Zone

At B1, a total of nine drill holes targeted the intense alteration and structure intersected during the 2023 drill campaign, as these features often occur in close proximity to high grade uranium mineralization. Five drill holes intersected anomalous radiation over a total strike length of 600m. Drill hole PLN24-133 targeted an area near the northern end of the B1 shear zone where a significant change in Athabasca Sandstone depth was expected and encountered a basement wedge in excess of 120m downhole thickness within the sandstone exhibiting strong alteration and deformation (see Cross Section for line 2850S below). Figure 1 shows the lower structural Athabasca Unconformity at a depth of 291.2m, with significantly structurally disturbed sandstone beneath. An extremely graphitic structure was intersected within this wedge (see Figure 2), and in all follow up drilling on section and along strike. Drilling on line 2850S with PLN24-138 and PLN24-142 and step out drilling on line 2820S with PLN24-144 confirmed that the strike of this very significant offsetting reverse structure appears to be discordant to the B1 main shear, and likely related to the Harrison fault, a significant regional structure which played an important role in the development of the Athabasca basin.

This magnitude of displacement along wide and strongly graphitic basement faults is highly favorable, and structurally comparable to what is seen at some of the largest uranium deposits in the basin. This now provides a number of drill targets for high grade uranium mineralization including the unconformity contacts, as well as the basement “nose” at the terminus of the wedge within the sandstone, with a focus on where the A1 and B1 structures intercept this offsetting reverse fault.

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 thicknesses are yet to be determined.

The Company contracted Patterson Geophysics Inc. (“Patterson“) to complete 65 line-km of fixed loop SQUID electromagnetic survey coverage (FL-SQUID-EM) over the B1 target area, to measure the induced electromagnetic (“EM“) fields associated with sandstone alteration effects as well as the response to dipping basement conductors. A trace of this conductor model projected to surface is shown on Map 1, and notably deviated in strike from the original B1 conductor model. The data collected by Patterson was used to target and successfully drill the large graphitic structure associated with the basement wedge intersected in PLN24-133.

Dias Geophysical Ltd. completed the 3D DC resistivity and induced polarization (DCIP) over the northern A1 area hosting the JR Zone, and the B1 area, using their DIAS32 system. F3 has engaged a contractor to process and perform 3D inversion modeling of resistivity and EM geophysical data jointly and in conjunction with all the drilling data to better resolve thin basement hosted conductors.

Initial Exploration Services Inc. has been contracted to conduct a ground gravity survey over the southwest section of the PLN and Broach properties. The survey is currently focusing on surveying the lakes and waterbodies using ice cover, with the remainder of the survey area to be infilled in late spring, and F3 aims to disclose those results once all the data has been collected and interpreted.
