F3 Hits Strongest Hole to Date 3.82m of Off-scale (>65,535 cps)

Extends JR Zone to 105m in Length
Kelowna, British Columbia–(Newsfile Corp. – March 27, 2023) – F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) (“F3” or “the Company”) is pleased to announce scintillometer results from the final nine holes of the winter drill program at the JR Zone on the Patterson Lake North (“PLN”) Property, including five high grade intercepts. Drill hole PLN23-060 collared on line 060S has intersected the strongest radioactivity to date at the JR Zone. It was collared up dip of hole PLN23-052 (see news release February 21, 2023) and intersected radioactivity over 17.5m, including 3.82m of continuous off-scale radioactivity >65,535 cps between 244.0m and 247.82m. PLN23-061 stepped out further to line 075S and resulted in 14.0m of mineralization, including 2.81m of composite off-scale (>65,535 cps) radioactivity within 5.08m of composite radioactivity >10,000 cps. An additional drill hole was added to the program stepping out further along strike on line 090S, where PLN23-062 intersected 6.0 m of composite radioactivity including 1.0m of continuous off-scale (>65,535 cps) radioactivity. These holes expanded the strike length of the JR Zone by another 30m, to a current length of 105m.Raymond Ashley, Vice President Exploration, commented:”With the final nine holes of the winter 2023 drill program the technical team is delighted to announce the strongest off-scale radioactivity drilled so far at the JR Zone with infill hole PLN23-060 on line 060S, making it the best hole to date. Moreover, the two holes which have expanded the JR Zone to a current length of 105m both intersected off-scale radioactivity >65,535 cps, hole PLN23-061 which stepped out to line 075S and hole PLN23-62 which stepped out further to line 090S. Additional holes will be planned for the summer program on section 30N as the single hole drilled on that section, PLN23-055, did not intersect mineralization. This is a fantastic ending to a very successful winter program of growing the JR Zone along strike towards the south within the A1 main shear zone, following the direction in which strong continuity of high grade mineralization had been established earlier in the drill program.”Drilling Highlight:PLN23-06017.5m composite mineralization from 231.5m – 253.5m, including4.98m composite mineralization of >10,000 cps between 243.17m – 252.83m, further including 3.82m of continuous off-scale (>65,535 cps) radioactivity from 244.00m – 247.82m (see Photo 1.)Main Intercepts:PLN23-054 (line 075S):14.5m composite mineralization from 244.0m – 269.0m with a peak radioactivity of 6,600 cps from 248.5m – 249.0mPLN23-056 (line 030S):11.5m composite mineralization from 237.5m – 249.0m, including1.34m continuous mineralization of >10,000 cps radioactivity between 247.16m – 248.50m with a peak of 32,300 cps PLN23-057 (line 045S):7.0m composite mineralization from 246.0m – 268.5m with a peak radioactivity of 1,400 cps from 252.0m – 252.5mPLN23-058 (line 060S):1.0 m continuous mineralization from 253.0m – 254.0m with a peak radioactivity of 360 cpsPLN23-059 (line 045S):17.0m composite mineralization from 238.5m – 255.5m, including1.32m composite mineralization of >10,000 cps radioactivity between 243.18m – 254.00m with a peak radioactivity of 31,100 cps PLN23-061 (line 075S):14.0m composite mineralization from 246.0m – 260.0m, including5.08m composite mineralization of >10,000 cps radioactivity between 246.71m – 254.93m, further including 2.81m of composite off-scale (>65,535 cps) radioactivity PLN23-062 (line 090S):6.0m composite mineralization from 240.5m – 256.5m, including1.0m continuous off-scale (>65,535 cps) radioactivity between 246.5m – 247.5m 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.  Photo 1: PLN23-060 Drill Core Photo  To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8110/159913_ac1b5691e49bdb6e_002full.jpgTable 1.
