Ore Mining and Processing
The ore is mined from various different pits. This is ideal for selective mining and in-pit blending to provide ore to meet customer specifications. 

A crushing, washing and screening plant processes the run-of-mine product. A plant has been installed to beneficiate off grade ore, which has extended the life of the mine.

At the mine, a computerised geological database is used for planning, scheduling and grade control. The analytical results of all blast holes are continuously reconciled with the computer-generated grade models to ensure that the correct grade is blasted before being transported to the treatment plant. A continuous sampling process at various points in the treatment and loading plants ensures the production of a consistent grade of ore that meets customer requirements.
