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.

· It has been established that the distribution of gold by size class is uneven. Its content in size classes ranges from 2.2 g/t (−0.045 + 0 mm) to 7.2 g/t (−0.2 + 0.1 mm). This distribution pattern is a sign of the presence of large and medium-sized gold particles in the crushed ore in free form and in rich intergrowths.
