TORONTO, CANADA (By Power Metallics, 19.2026, Words: 274) — Power Metallic Mines Inc. provided preliminary metallurgical results performed by SGS Canada Ltd at its laboratories based in Quebec City, QC, and Lakefield, ON, from representative samples of Lion zone mineralization.
An initial lock cycle test returned a sulphide concentrate grading 25.8% copper containing very high metal recoveries of copper (98.9%), palladium (93.9%), platinum (96.8%), gold (85.0%) and silver (88.9%), exceeding Power Metallics most optimistic estimates for recovery prior to this test work. Â
As previously reported the Cu mineralization at Lion is contained within coarse grained chalcopyrite and cubanite and Cu was expected to respond well to conventional sulphide concentration methods. These initial metallurgical tests were designed to determine the recovery potential of the PGEs, Au, Ag, and Ni.
The Lion deposit has two zones of mineralization defined by drilling, consisting of a High-Grade zone (HG) and a Low-grade Zone (LG). As reported on 16 Oct. 2025, Power Metallic compiled a series of drill core reject material from the Lion deposit spatially representative of the known mineralization across strike and down plunge within the deposit. Three composites were prepared, HG (103 samples from 15 drill holes); LG (99 samples from 10 drill holes); and a Blended composite based on modeled volumes for Lion (approx. 50/50 ratio).
Initial sulphide flotation concentration tests by SGS showed similar recovery characteristics for all 3 composites, and a decision was made by SGS to carry out a locked cycle test (LCT) on the blended composite as representative of run-of-mine feed for conventional sulphide flotation. The LCT test is a laboratory scale flowsheet of a potential future mill circuit for the Lion deposit.
