Mining & Processing
Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.
