F3 HITS 2.05M OFF SCALE >65,535 CPS IN FIRST HOLE OF WINTER PROGRAM AT JR ZONE

F3 Uranium Corp. has released initial scintillometer results from the first completed drill hole of the current winter drill program on the Patterson Lake North (PLN) property, which includes two high-grade intercepts. Drill hole PLN24-116 tested for mineralization between PLN23-061 (see news release dated May 15, 2023) and PLN23-074 (see news release dated Nov. 13, 2023) on section line 075S and intersected mineralization within a 16.5-metre interval, including 2.05 m of off-scale radioactivity (greater than 65,535 counts per second), 1.80 m of which is continuous. A thin, lower mineralized zone up to 23,600 cps starting at 272 m was also intersected and marks the first intersection of strong radioactivity below the JR zone.

A second diamond drill has also begun coring on the JR zone before moving approximately three kilometres grid south to start exploration in the B1 area where drill holes from last year provided strongly encouraging results, including significant alteration, structures and highly anomalous geochemistry.

As the Dias 3-D resistivity survey is days away from being completed, preparations are under way at site for the next phase of ground geophysics. A stepwise moving-loop time-domain electromagnetics (SWML) survey totalling approximately 60 line km will be conducted over the B1 area, with ideal loop size parameters to properly resolve the basement-hosted B1 conductor. This new survey will update and refine the company's electromagnetic plate model, which will then be integrated with the resistivity data to provide additional drill targets.

Drilling highlight

PLN24-116 (line 075S):

• 16.5 m mineralization from 224 m to 240.5 m, including:
  • 6.05 m composite high-grade radioactivity (greater than 10,000 cps) between 224.85 and 232.40 m, including:
  • 2.05 composite off-scale radioactivity (greater than 65,535 cps) between 227 and 231.25 m;
  • 0.5 m mineralization from 272 m to 272.5 m with up to 23,600 cps.

Natural gamma radiation in the drill core that is reported in this news release was measured in counts per second (cps) 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 thickness are yet to be determined but thecCompany estimates true thickness of the reported intervals in this news release to be close to reported interval widths.

About Patterson Lake North

The company's 4,078-hectare, 100-per-cent-owned Patterson Lake North property (PLN) is located just within the southwestern edge of the Athabasca basin in proximity to Fission Uranium's Triple R and NexGen Energy's Arrow high-grade world-class uranium deposits, which is poised to become the next major area of development for new uranium operations in Northern Saskatchewan. PLN is accessed by Provincial Highway 955, which transects the property, and the new JR zone uranium discovery is located 23 km northwest of Fission Uranium's Triple R deposit.

About F3 Uranium Corp.

F3 Uranium is advancing the newly discovered high grade JR zone on the PLN property in the western Athabasca basin. This area of Saskatchewan is poised to become the next uranium producer and home to large uranium deposits, including Triple R, Arrow and Shea Creek. F3 Uranium currently holds 18 projects across the Athabasca basin.
