F3 Uranium Hits 57,100 cps in Widest Mineralized Interval to Date

Steps Out 60m From Discovery Hole and Extends Strike Length to 75m.

Kelowna, British Columbia–(Newsfile Corp. – February 21, 2023) – F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) (“F3” or “the Company“) is pleased to announce scintillometer results from four additional holes of the ongoing 20-hole winter drill program at the JR Zone on the Patterson Lake North (“PLN”) Property, including three high grade intercepts. Drill hole PLN23-050 was collared as a step out on line 045S and intersected the widest mineralized interval to date over 21.0m, including 3.19m of composite radioactivity with >10,000 cps and a peak of 57,100 cps at a downhole depth of 255.0m. PLN23-052 stepped out further to line 060S and resulted in 11.0m of mineralization, including 1.70m of continuous radioactivity with >10,000 cps and a peak of 53,600 cps. Infill drillhole PLN23-053 on line 030S intersected radioactivity over a 9.5m interval between 245.5m and 255.0m including 2.10m of composite radioactivity with >10,000 cps and a peak of 48,100 cps.

Raymond Ashley, Vice President Exploration, commented:

“The technical team is delighted to announce scintillometer results of step out hole PLN23-050 on line 045S where mineralization was encountered over a 21.0m interval within the A1 main shear zone, including the high grade core. We are continuing with disciplined step out drilling and growing the JR Zone further along strike to the south, which has now been defined over a total length of 75 meters to section line 060S where PLS23-052 intersected high grade mineralization with up to 53,600 cps. Although PLS23-051 on section line 00SN tested the MSZ closer to the Athabasca Unconformity and did encounter radioactivity, we anticipate focusing the remaining winter program on basement hosted mineralization. The JR Zone continues to impress with high grade intercepts as we define it along strike while also building some width with infill drill holes.”

Drilling Highlight:

PLN23-050 (line 045S):

• 21.0m mineralization from 248.5m – 269.5m, including
  • 3.19m composite mineralization of >10,000 cps radioactivity between 252.10m – 256.00m with a peak of 57,100 cps over 0.50m from 255.0m – 255.5 m (see Photo 1.)

Main Intercepts:

PLN23-051 (line 00N):

• 1.0m mineralization from 204.5m – 205.5m

PLN23-052 (line 060S):

• 11.0m mineralization from 245.0m – 256.0m, including
  • 1.70m continuous mineralization of >10,000 cps radioactivity between 253.00m – 254.70m with a peak of 53,600 cps over 0.50m from 254.0m – 254.5m

PLN23-053 (line 030S):

• 9.5m mineralization from 245.5m – 255.0 m, including
  • 2.10m composite mineralization of >10,000 cps radioactivity between 251.10m – 254.30m with a peak of 48,100 cps over 0.50m from 252.00m – 252.50m

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. All depth measurements reported are down-hole and true thickness are yet to be determined. 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 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.
