Power Metal Resources (AIM:POW) has identified the Rapids Fault Structure on its Perch River uranium property in the Athabasca Basin as mineralogically and geochemically "fertile", citing sudoite, hydrothermal tourmaline and dolomite alongside strong radiogenic lead signatures as vectors toward potential unconformity-related uranium mineralisation.
Supplementary December 2025 sampling from the JV's 2025 drill programme returned a 779 ppm boron peak in PR25-01, 206Pb/204Pb ratios exceeding 100 in PR25-04A, and anomalous lead isotope and pathfinder element trends spread along at least 400m of strike, positioning Perch River as a top priority.
"These supplementary results fundamentally upgrade the prospectivity of the Perch River property," said Sean Wade, Chief Executive Officer of Power Metal Resources.
The Perch River property is held under Power Metal's uranium‑focused joint venture with Fermi Exploration, with Fermi's technical team completing a six‑hole, 1,563m diamond drill programme in June-July 2025 and the JV completing higher‑density core sampling in December 2025 to refine targets.
Fermi's technical interpretation is that the 2025 drilling intersected the distal, upper halo of a hydrothermal system and that the high‑temperature core-and the primary unconformity‑style uranium target-remains untested at greater depths, making Perch River the JV's priority for follow‑up deeper drilling.
