F3 Hits Anomalous Radioactivity on A1B Shear 2.6km South of JR Zone

Off-Scale Mineralization at JR Zone Extended 25m Southward

September 14, 2023 (Source) — F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUF) (“F3” or “the Company“) is pleased to announce results from thirteen holes of the ongoing summer drill program on the Patterson Lake North (“PLN”) Property, including PLN23-095 2.6km south of the JR Zone testing the recently discovered A1B Shear Zone, which intersected anomalous radioactivity. Additionally, PLN23-093 was drilled 840m further to the south along strike and intersected intense alteration and dissolution in the sandstone and strongly deformed and clay altered basement rocks.

Concurrently at the JR Zone, PLN23-090 extended off-scale mineralization by 25m towards the south from PLN23-062 (see NR May 15, 2023). Drill hole PLN23-090 on line 120S intersected mineralization over a 14.0m interval, including 1.65m of high grade (>10,000 cps), of which0.50m was off-scale radioactivity (>65,535 cps) between 240.00 and 240.50m. PLN23-097 on line 045S intersected mineralization over an 11.0m interval, including 2.69m of high grade (>10,000 cps), of which0.25m was off-scale radioactivity (>65,535 cps) between 219.75m and 220.00m, resulting in a high grade dip extent of 52m on line 045S.

JR Zone drilling, as well as exploration drilling, continues with two diamond drills and one sonic drill. As a result of the recently over-subscribed private placement, grossing aggregate proceeds of C$20 Million in flow through funds (see NR September 12, 2023), and strong drilling results, the summer drill program will be further extended into late fall and consist of up to 54 drill holes totaling approximately 20,000m.

Raymond Ashley, President, commented:

“As the summer drilling program transitions into an expanded fall program, we are starting to focus on exploration drilling, with the goal of characterizing areas for more detailed follow-up drilling during 2024. The A1B EM conductor was first confirmed to correspond to a major shear zone with PLN23-078 (see NR August 14, 2023); PLN23-095 was drilled as a follow up, testing both the A1 and A1B shear zones on section. This resulted in the intersection of several additional shears ranging in thickness from 5 to 10 meters both between the A1 and A1B main shear zones, as well as beyond the main A1B shear where PLN23-095 intersected anomalous radioactivity at depth within the approximately 400m wide structural corridor. Drilling at the JR Zone continues as well, with some drill holes exploring the peripheral regions to the high grade mineralization, as well as expanding the high grade domains on lines 045S and 120S.

“PLN23-093 targeted the A1B main shear near the projected Athabasca Unconformity; due to significantly more sandstone than expected, the structure was overshot by approximately 100m. The intense sandstone alteration and dissolution was coupled with drill core loss encountered over a 140m interval, in line with the projection of the A1B shear, followed by strongly deformed and clay altered basement rocks. These are features associated with JR Zone mineralization on the A1 main shear zone that, coupled with the radioactivity intersected in PLN23-095, reinforce the potential for A1B to host uranium mineralization.”

JR Zone Drilling Highlights:

PLN23-090 (line 120S):

14.0m composite mineralization from 231.5m – 248.50m, including
- 1.65m compositemineralization of >10,000 cps radioactivity between 239.20m – 245.20m including 0.50m off-scale radioactivity (> 65,535 cps) between 240.00m and 240.50m

PLN23-097 (line 045S):

11.0m mineralization from 212.5m – 223.5m, including
- 2.69m compositemineralization of >10,000 cps radioactivity between 215.65m – 224.24m including 0.25m off-scale radioactivity (> 65,535 cps) between 219.75m and 220.00m

Exploration Drilling Highlights:

PLN23-093 (line 3450S), A1B Shear Zone

75.0m cumulativecore loss in Athabasca Sandstone between 140.0m and 287.0m
- Approximately 100m up-dip of the A1B Main Shear projection to the unconformity
- Indicative of large scale sandstone dissolution due to intense alteration above the projected A1B shear zone

PLN23-095 (line 2610S), A1B Shear Zone

0.5m radioactivity of 300 cps from 610.00m to 610.50m
- First occurrence of anomalous radioactivity, approximately 100m past the main A1B shear zone within the 50m wide A1B shear zone complex

Table 1. Drill Hole Summary and Handheld Spectrometer Results

Handheld spectrometer composite parameters:
1: Minimum Thickness of 0.5m
2: CPS Cut-Off of 300 counts per second
3: Maximum Internal Dilution of 2.0m

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 but the Company estimates true thickness of the reported intervals in this news release to be close to reported interval widths.
