F3 Uranium Corp. announced initial scintillometer results from the last eleven drill holes of the fall drill program on the Patterson Lake North ("PLN") Property, including multiple high grade intercepts. In particular drill hole PLN23-110 tested for mineralization up dip of PLN23-101 and intersected mineralization within a 11.5m interval including 1.50m of continuous off scale radioactivity (>65,535 cps).

Drill hole PLN23-112 tested mineralization down dip of PLN23-068 and intersected mineralization within a 11.5m interval including 1.35m of composite off-scale radioactivity (65,535 cps). The southern end of the A1 trend features significant vertical displacement; drill holes PLN23-078 and PLN23-093 were cored into bedrock with no Athabasca Sandstone present. Drill holes grid south including PLN23-115 and PLN23-111 have approximately 230m of sandstone cover; this indicated the presence of a vertically offsetting and likely cross cutting structure.

At the B1 area, exploration drilling is encountering increasingly prospective geology. PLN23-111 was drilled approximately 200m grid north of PLN23-093 where significant boron values were reported and cored a significant section of intensely brecciated, faulted and clay altered Athabasca Sandstone. The strongly graphitic and clay altered basement hosted B1 shear zone was intersected below.

This is indicative of significant reactivated structures favorable for hosting uranium mineralization. A total of 53 drill holes totaling 19,800 meters have been completed since the summer drill program began in June, and an additional 5 targets have casing already set in anticipation of the upcoming winter 2024 drill campaign slated to begin in early January 2024. 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. 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.
