F3 Uranium Hits 5.5 Metres Of 7.56% U3O8 At JR Zone

F3 Uranium (TSXV: FUU) is reporting a significant intersect of U3O8 at its Patterson Lake North project in the Athabasca region, following the receipt of assay results for an ongoing drill program. The company has also highlighted a notable interval of boron mineralization at the A1B area, suggesting uranium may be again found on the property.

Highlights from the results include:

  • PLN23-084: 1.0 metre of 2.22% U3O8 from 237.5 metres
  • PLN23-086: 5.5 metres of 7.56% U3O8 from 229.5 metres
  • PLN23-090: 10.0 metres of 1.29% U3O8 from 232.0 metres
  • PLN23-093: 2.0 metres of 5,557 ppm boron from 354.5 metres in sandstone
  • PLN23-097: 13.0 metres of 1.34% U3O8 from 210.0 metres

The high grade intercepts come from continued drilling at the JR Zone, while the boron discovery comes from the A1B area of the PLN property, which is found 3.5 kilometres away. Hole PLN23-093 marks the first geochemical exploration drill results from A1B, where strong boron values were intersected within sandstone. Notably, F3 has only intersected boron at the PLN property above the JR Zone, where boron is found in the Athabasca Sandstone immediately above the zone.

“It is our view that in comparison to the JR Zone, the A1B system represents an area of widespread structural complexity, with evidence of significant re-activated reverse structures extending into the sandstone. With this complexity also comes opportunity and I see the A1B shear area among the most prospective places to make the next discovery, considering these first geochemistry results. Going forward we will refer to the A1B shear zone as B1 to differentiate it more clearly from the A1 shear zone, as a separate structure,” commented VP of Exploration Sam Hartmann on the results.

F3 Uranium last traded at $0.405 on the TSX Venture.
