April 22, 2024 – Outcrop Silver & Gold Corporation (TSXV:OCG, OTCQX:OCGSF, DE:MRG) ("Outcrop Silver") is pleased to announce breakthrough results from the initial gravimetric concentration test work as part of the program to enhance the already high-recoveries at Santa Ana. This phase of testing has proven the effective recovery of silver and gold through mechanical gravimetric processes before conventional flotation.
Highlights
Gravimetric concentration test successfully confirmed the recovery of silver from mineralized material at Santa Ana before the conventional flotation processing.
The resulting silver and gold gravimetric concentrate yielded 2,883 grams per tonne of silver and 164.12 grams per tonne of gold.
"We are thrilled about the latest gravimetric concentration tests having not only achieved concentrate grades well exceeding 150 gold equivalent grams per tonne — a key marker for highly marketable concentrates — but have also demonstrated significant potential for enhancing our overall recovery rates. With a 7% recovery via gravimetric methods complementing our 93% flotation recoveries, and without the use of cyanide, we are setting new benchmarks for economic viability and reducing our environmental footprint in precious metals mining," comments Ian Harris, President and CEO. "This positions the Santa Ana project as one of the world's highest-grade primary silver endeavors, promising exceptional recoveries and highly marketable concentrates. We have already initiated the next phase of test work to integrate gravimetric and flotation methods and look forward to sharing these promising results as soon as they are available."
