F3 Uranium (TSX‑V:FUU) has intersected ‘strong’ alteration and structure in a 950m step‑out from its Tetra zone discovery at the Patterson Lake North Project in the Athabasca Basin in Saskatchewan, Canada.
The company completed two drill holes as part of its 2026 summer exploration program.
PLN26‑229 cut strong bleaching at the top of the basement, a style comparable with alteration seen at the Tetra zone, and returned hand‑held scintillometer readings exceeding 300 counts per second (cps) over two 0.5m intervals: 688–688.5m (peak 480cps) and 809.5–810m (peak 380cps).
“PLN26-229 represents a significant 950m stepout from Tetra, and the presence of very similar basement bleaching of that intensity this far out demonstrates that the alteration system is considerably more extensive than the area immediately surrounding the Tetra discovery,” VP for Exploration Sam Hartmann says.
The company plans at least one follow‑up hole at Target Area 1 during the current program, incorporating geological and structural information from PLN26‑229.
F3 Uranium’s 42,960‑hectare Patterson Lake North Project sits within the southwestern edge of the Athabasca Basin near Paladin Energy’s (ASX:PDN) Triple R and NexGen Energy’s (ASX:NXG) Arrow ‘high‑grade’ uranium deposits.
Patterson Lake North comprises three properties: the 4,074‑hectare PLN property, the 19,864‑hectare Minto property, and the 19,022‑hectare Broach property hosting the Tetra zone discovery.
