A technique for recovering gold called "heap-leach extraction" entails crushing ore and piling it high on a lined pad.. In order to separate the gold from the ore, a chemical solution, frequently cyanide, is given to the heap.. The gold is recovered by gathering and processing the gold-containing solution.This technique is efficient at extracting gold from low-grade or refractory …

The heap leach pad working inventory is 3mt at 0.72 g/t gold and 8 g/t silver containing 700,000 ounces of gold and 800,000 ounces of silver. The heap leach pad is considered to be a working inventory because the active ore placement lift has a planned 150-day leach cycle to realise of the estimated total recovery.
