John Miniotis, President and CEO of AbraSilver Resource Corp (TSX.V:ABRA – OTC:ABBRF), joins us to outline the substantial improvements to the silver and gold recovery rates through recent metallurgical optimization work on the Oculto Deposit at its wholly-owned Diablillos property in Salta Province, Argentina.


Recovery rates at the Oculto deposit are expected to range between 82% – 86% for silver and 84% – 89% for gold.These results represent a significant increase over the average recovery rates of 73.5% for silver and 86% for gold used in the 2022 Preliminary Economic Assessment. 


The latest program involved metallurgical testing of four composites from the Oculto deposit, including gravity separation testing and cyanidation of the gravity tailings for the recovery of gold and silver. The ability to recover a substantial amount of gold and silver through the use of simple gravity separation offers major advantages, by increasing recovery rates and also lowering the overall processing costs.


The Company will be incorporating these results into their updated Mineral Resource estimate later this year and the Pre-Feasibility Study slated for the beginning of next year as key milestones.
