The operating cost of a given grinding circuit is basically a function of the ore type. Energy is no longer a cheap commodity. While some British Colombia operations are fortunate to obtain energy at a very low cost (¢ to 2¢/kWh), some of the Southwestern operations are already paying approximately 4¢/kWh.
