Surface mining operations involve high levels of complexity and uncertainty that last for many years and require huge capital investment and risk. Each openpit mine is unique, based on the physical characteristics of the ore deposit and on the operational parameters of the
"In the broader mining industry, the opportunity cost of not producing a unit of production during this high price period meant that most miners took a "volume over cost" approach; the benefits of being able to produce more outweighed the increased costs that resulted" Marius Kloppers, CEO BHP Billiton Presentation to Brisbane Mining Club, 17 October 2012 "We are right at the bottom ...
Mining cost per tonne of ore Processing cost per tonne of ore Overhead cost per tonne of ore Processing costs and recoveries can vary based on geological characteristics such as mineralogy, hardness, clay content, and degree of oxidation, depending on the loion of the deposit . Mine (external) Cutoff NSR. The mine cutoff NSR is described as material that does not need to be mined .
· If you try to reduce explosive costs alone you may raise drilling cost per ton, secondary breakage costs, digging costs, hauling costs, and crushing costs. If explosives cost would increase but produce better breakage and cost reductions could made in the other production costs then total production cost may radically decrease.

Generally, operating costs are expressed in total 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 openpit mines. It can be. Prepared for: MeMO 2016 Reducing Mining Costs and Value
