production at any cost. During the height of the mining boom, record-breaking commodity prices notionally supported the development of marginal high-cost, low-productivity mineral deposits. As commodity prices dropped, companies responded by slashing costs – a traditional response to a shifting market cycle. Which begs the question:
The cost of sorting 1 ton of $68.64 ore from the run-of-mine product is $1.95. Expressed in another way, the sorting cost per ton of run-of-mine ore is 1.95/6.51 or $0.30. The cost of mining 1 ton of run-of-mine ore is $2.34. The cost of transporting ore from the mine to the mill on contract .

consequences of undertaking this option. Traditionally, contract mining has come at a cost premium of about 15% to 20% compared to an owner mining scenario. However, due to the large number of junior mining companies entering the mining arena in South Africa contract mining rates have increased, with cost premiums as high as 50% being reported.
A negative spin-off of poor mining conditions is an increase in accident damage on mechanized machines. Therefore an increase in severity impacts on the machine cost per hour (affecting the dealer) and productivity decreases and increase in accident damage (affecting the customer) result in a lose-lose situation for both parties.
