F3 Hits 2.5m of 18.6% U3O8 within 3.2% over 15.0m at 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."
