The Mining Process

The Mining Process

Gold bearing ore is transported to stockpiles ready for processing. The lowgrade ore found at Macraes has driven investment in new and innovative technology and engineering, making the operation more efficient. The low unit costs remain essential for the Macraes Operation as the ratio between the amount of ore dug to the amount of waste rock dug is 1:10 (also known as the stripping ratio). So ...
