Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.

The three primary and secondary crushing stations each crush 5000 tons of ore an hour (t/h) into particles smaller than 150 mm. This material is then conveyed to a 250,000 t surge stockpile prior to being fed into the processing plant. When the ore is fed into the processing plant it first enters the scrubbers, before being sent to wet screening.
