A generic mining cost structure There are two main types of costs for mining projects operating and capital costs Figure 1 is a schematic representation of the generic cost breakdown for mines A brief overview of what these costs entail is discussed in the following sections
• U/G mining cost = $ 28 per tonne of ore • Open pit mining cost = $ per tonne of ore • Stripping cost $ per m3 of waste • MASR 28 / = waste 1 ore • O/P mining is more economical up to the value of of stripping ratio • For SR U/G mining is more economical for that part of the ore body
Global costs varied significantly with regions like Kazakhstan Peru Mexico and the Democratic Republic of the Congo DRC emerging as particularly cost efficient Production costs per pound ranged from as low as $ at KAZ Minerals Bozshakol mine in Kazakhstan to over $ per pound at operations run by companies like BHP and Lundin
