costs per ton of ore mined; for example, South African coal mining costs are quoted as rands per ton of coal produced. Figure 3 shows typical operating cost splits for relevant activities in the production cycle in open-pit mines. It can be seen that that hauling typically accounts for a significant proportion of the operating costs.
