If drill and blast costs need to be increased to improve the quality of fragmentation, these costs are far outweighed by the reduction in mill operating costs – typically 7 to 10 times any increase in mine costs. At the same time, the concentrator must be prepared to take advantage of the much improved, higher quality feed material.
