F3 GROWS JR BY 50% AND HITS STRONGEST RADIOACTIVITY TO DATE WITH 6.0M OFF-SCALE (>65,535 CPS)

F3 Uranium Corp. has released scintillometer results from the initial eight holes of the continuing 30-hole summer drill program at the JR zone on the Patterson Lake North (PLN) property, including four high-grade intercepts. Drill hole PLN23-068 tested for mineralization 22 metres up dip of the high-grade intercept reported in PLN23-060 (see news release dated April 17, 2023) on line 060S and intersected mineralization over a 19 m interval, including six m off-scale radioactivity (greater than 65,535 counts per second) between 234 m and 245 m, five m of which are continuous. The JR zone was extended south to line 135S, a 50-per-cent increase in the JR zone strike length to 156 m, after stepping out 30 m from line 105S, where PLN23-66 hit 16.5 metres of composite mineralization between 219 m and 260.5 m.

Sam Hartmann, vice-president of exploration, commented: "We are pleased with the rapid progression of this summer drill program and the results generated so far. In particular, PLN23-068 returned exceedingly strong results on line 60S, with mineralization starting only approximately 17 metres vertically below the Athabasca unconformity, which remains a target for this drill program. So far, we are sticking to the script and growing the mineralized footprint along strike and up dip towards the unconformity as planned. PLN23-067 stepped out to line 135S, and although the radioactivity is less intense, there is mineralization over a 16.5-metre interval, which sets us up for further stepouts towards the south. A second sonic drill, in addition to a second diamond drill later this month, will see the inclusion of some exploration drilling along the A1 main shear, as well as contribute to JR zone expansion drilling."

Natural gamma radiation in the drill core that is reported in this news release was measured in counts per second, using a hand-held Radiation Solutions RS-125 scintillometer. The company considers greater than 300 cps on the hand-held spectrometer as anomalous, greater than 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. Samples from the drill core are split in half on site and are standardized at 0.5 m lengths. One-half of the split sample will be submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025:2005-accredited facility) in Saskatoon, Sask., for lithogeochemical analysis using its "uranium package."

All depth measurements reported are down hole, and true thicknesses are yet to be determined, but the company estimates true thicknesses of the reported intervals in this news release to be close to reported interval widths.
