Power Metallic Reports Lion Zone Recoveries of 98.9% Copper, 93.9% Palladium, 96.8% Platinum, 85% Gold and 88.9% Silver from Initial Metallurgical Results as Reported by SGS Canada Inc.

Core Insights - Power Metallic Mines Inc. has announced preliminary metallurgical results from SGS Canada Ltd, indicating high metal recoveries from the Lion zone mineralization, with copper recovery at 98.9% and a concentrate grading 25.8% copper, surpassing previous estimates [1][5][9] Metallurgical Testing Results - The initial Lock Cycle Test (LCT) showed exceptional recoveries for various metals: Copper (98.9%), Palladium (93.9%), Platinum (96.8%), Gold (85.0%), and Silver (88.9%) [1][6][9] - The mineralization at the Lion deposit is primarily composed of coarse-grained chalcopyrite and cubanite, which are expected to respond well to conventional sulphide concentration methods [2][3] Composite Samples and Testing - Three composite samples were prepared for testing: High-Grade (HG) with 103 samples, Low-Grade (LG) with 99 samples, and a Blended composite representing a 50/50 ratio [3][4] - The LCT was conducted on the Blended Composite, which is considered representative of the run-of-mine feed for conventional sulphide flotation [4][5] Recovery Performance - The LCT results indicated a high-grade concentrate containing 25.8% Cu, 1.2% Ni, 4.83 g/t Au, 41.4 g/t Pd, 23.4 g/t Pt, and 159 g/t Ag, with robust recoveries across all tested metals [6][9] - The results suggest that the previous recovery estimates of 80% for all metals were significantly underestimated, indicating a potential for higher returns from the Lion zone mineralization [9][13] Future Prospects - Power Metallic is considering a Phase 2 study to explore the creation of value-added products based on the promising metallurgical results [14] - The company aims to leverage the high recovery rates for future copper equivalent calculations, which will enhance the economic viability of the Lion project [13]
