F3 Uranium Hits 22.9 % U3O8 over 1.5m within 4.20% U3O8 over 11.0m at PLN JR Zone

Kelowna, British Columbia–(Newsfile Corp. – February 6, 2023) – F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUF) (“F3” or “the Company“) is pleased to announce it has received final uranium assay results for the remaining fall 2022 drill holes at the JR Zone on the Patterson Lake North (“PLN”) Property where off-scale radioactivity was previously confirmed as high grade uranium mineralization (see Press Release Dec 22, 2022).

Drill hole PLN22-038 targeted up dip from hole PLS22-035 and returned an 11.0 m interval averaging 4.20% U₃O₈ including a high-grade 4.5 m interval averaging 9.8% U₃O₈, which further includes the ultra-high-grade core which assayed 22.9% over 1.5 m. PLN22-038 was the second of three mineralized holes completed on line 00N, in addition to a fourth mineralized hole on line 015S. Assay results from all mineralized drill holes of the fall 2022 program are disclosed below in Table 1.

Raymond Ashley, Vice President Exploration, commented:

“Assay results from these remaining three mineralized drill holes continue to validate the high grade nature of the JR Zone, situated within the A1 main shear zone. Strong results up dip of the discovery hole, with PLN22-038 and PLN22-041 respectively, as well as along strike to the south with PLN22-040 substantiate the JR Zone which is currently being further defined and expanded during the ongoing winter drill program.”

Drilling Highlights:

PLN22-038 (line 00N): mineralized intervals

• 11.0 m @ 4.20% U₃O₈ (240.5 m to 251.5 m), including:
• 4.5 m @ 9.8% U₃O₈ (244.0 m to 248.5 m), further including:
• 1.5 m @ 22.9% U₃O₈ (245.5 m to 247.0 m)
