Discovery Silver Corp. (DSV) released results from its pre-feasibility study metallurgical test program on samples from its Cordero project.
This program represents the most comprehensive test work completed on Cordero to date.
Silver recoveries of 94 per cent to 98 per cent lead, 89 per cent to 97 per cent zinc, and recoveries of 92 per cent to 96 per cent on high-grade samples of all major rock types.
Silver recoveries of 83 per cent to 92 per cent, with lead recoveries of 85 per cent to 92 per cent and zinc recoveries of 81 per cent to 89 per cent on medium grade samples of blended rock types.
Oxide-sulphide blend test work establishes oxide-specific recoveries of roughly 60 per cent for silver, around 40 per cent for lead and about 85 per cent for zinc via flotation; co-processing oxide mineralized material via flotation eliminates the need for heap leach processing at Cordero.
Test work overall confirmed higher recoveries than what was assumed in the 2021 Preliminary Economic Assessment.
Discovery Silver’s Interim CEO, Tony Makuch stated that these test results demonstrate the exceptional metallurgical properties of the Cordero deposit.
“Recoveries typically ranged from 85-95 per cent at an extremely coarse grind size of ~210 micron. On average sulphide recoveries came in higher than what was assumed in our PEA and were achieved at significantly reduced reagent consumption highlighting the potential for reduced operating costs for our study. In addition, our first ever flotation test work of an oxide-sulphide blend returned very positive results with economic recoveries for oxide mineralization for silver, lead and zinc through flotation. These results allow for the elimination of the heap leach circuit in our pre-feasibility study; this will streamline the crushing/grinding circuit, reduce upfront capital expenditures, and simplify the permitting process.”
