The heap leach pad working inventory of 3 Mt at 0.72 g/t gold and 8 g/t silver containing 0.07 Moz of gold and 0.8 Moz 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 100% of the estimated total recovery.

Heap Leaching of Gold and Silver Ores - ScienceDirect

A heap leach typically achieves ∼25% less gold recovery than a mill. The operating cost plus debt service for a medium-sized mill 3000 t/d is typically $39/t of ore treated whereas the comparable cost for the heap is $19/t equating to a differential operating cost plus debt service of $20/t for milling compared with heap leaching.


Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions. Modern day heap leaching which has a relatively low level of energy consumption is for example
