F3 Hits 2.5m of 18.6% U3O8 within 3.2% over 15.0m at JR Zone

Rhea-AI Summary

F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) has announced final assay results from its winter 2024 drill program at the PLN project. Highlights include:

- PLN24-137 in the JR Zone: 15.0m of 3.2% U3O8, including 2.5m of 18.6% U3O8 and 1.5m of 30.3% U3O8

- PLN24-152 south of Harrison Fault: 2.0m @ 0.024% U3O8 and 7.0m @ 0.014% U3O8, including 0.5m @ 0.051% U3O8

The company is focusing exploration on areas near the Harrison Fault and to the southeast, with PLN24-152 representing one of the highest priority exploration targets for follow-up outside the JR Zone.

Positive

• High-grade uranium mineralization in JR Zone with 15.0m of 3.2% U3O8, including ultra-high grade core of 1.5m at 30.3% U3O8
• Promising exploration results outside JR Zone, with PLN24-152 showing strongest geochemistry signatures to date
• Systematic drilling approach identifying potential high-grade mineralization targets

Negative

• Exploration results outside JR Zone still show significantly lower uranium grades compared to JR Zone

Kelowna, British Columbia--(Newsfile Corp. - July 30, 2024) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce final assay results from the winter 2024 drill program, including PLN24-137 which was cored in the JR Zone (see NR April 16, 2024) and which returned 15.0m of 3.2% U₃O₈, including a high grade 2.5m interval averaging 18.6% U₃O₈, further including the ultra-high grade core with 1.5m of 30.3% U₃O₈.

Exploration geochemistry for the continuing summer drill program has also been received up to hole PLN24-152 which focused on drill testing both the A1 main shear, as well as a related fault splay termed the "North Horse" grid south of the cross-cutting Harrison Fault, a significant structure corresponding to a vertical offset of approximately 130m. Two radioactive intervals (see NR June 12, 2024) corresponding to the main A1 and North Horse structures respectively yielded the strongest exploration geochemistry results outside of JR Zone to date, with the main A1 intersect assaying 0.045% U₃O₈, and the North Horse intersect assaying 0.014% U₃O₈ over 7 meters including 0.051% U₃O₈ over 0.5m (see Photo 1).

A series of shorter exploration drill holes have been completed on the main A1 shear infilling gaps, and although there are multiple areas warranting follow up, exploration drilling in the near term will focus on the areas near Harrison Fault, and to the southeast.

Sam Hartmann, Vice President Exploration, commented:

"We are very pleased with these ongoing results. Drillhole PLN24-152 stands out with the strongest geochemistry signatures to date outside of the JR Zone and represents one of the highest priority exploration targets for follow up. This hole targeted the intersect of the Harrison Fault and the A1 Main shear zone just south of the Harrison Fault. Targeting in this area now includes the Harrison Fault itself, and the areas of shear intersections with it. We are persistent in our efforts to hone in on potential high-grade mineralization indicated by encouraging results from our systematic drilling in this area."

Assay composite parameters:

1: Minimum Thickness of 0.5 m
2: Assay Grade Cut-Off: 0.05% U3O8 (weight %)
3. Maximum Internal Dilution: 2.0 m

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.

FAQ

What were the key uranium assay results from F3 Uranium's winter 2024 drill program at PLN?

The key result was from hole PLN24-137 in the JR Zone, which returned 15.0m of 3.2% U3O8, including a high-grade 2.5m interval averaging 18.6% U3O8, and an ultra-high grade core of 1.5m at 30.3% U3O8.

What were the significant exploration results for F3 Uranium (FUUFF) outside the JR Zone?

The most significant exploration result outside the JR Zone came from hole PLN24-152, which intersected 2.0m @ 0.024% U3O8 and 7.0m @ 0.014% U3O8, including 0.5m @ 0.051% U3O8, representing the strongest geochemistry signatures to date in the exploration area.

Where is F3 Uranium (FUUFF) focusing its exploration efforts following the summer 2024 program?

F3 Uranium is focusing its exploration efforts on areas near the Harrison Fault and to the southeast, with particular attention to the intersections of the Harrison Fault with the A1 Main shear zone and related fault splays.

What is the significance of the Harrison Fault in F3 Uranium's (FUUFF) exploration at PLN?

The Harrison Fault is a significant structure corresponding to a vertical offset of approximately 130m. It intersects with the A1 Main shear zone and is considered a high-priority target area for potential high-grade uranium mineralization.
