Mining Milling

The mill was originally designed with a capacity to process 4.8 million tonnes of ore per year but the actual mill throughput in 2011 was approximately 5.7 million tonnes per year The ore to be milled is managed through a number of stockpiles that receive ore of different metallurgical character and of different grade ranges and thus allow blending of the mill feed.
