The 500th Cummins engine will enter service at the massive Grasberg mining operations in Papua, Indonesia, in 2013.
No one mine in the world has as much mobile machinery as Grasberg. At the beginning of 2013, over 450 Cummins engines were in service at Freeport-McMoRan’s mine and port operations.
Built at an oxygen-depleted altitude of 4,285 metres (14,000 ft), Grasberg is a spectacular feat of engineering. It is the world’s largest copper and gold mine in terms of reserves, and its operations are on a scale unique even by the standards of modern mega-mining.
While the spectacular open pit dominates the landscape, one of the world’s largest underground mining operations is also part of the Grasberg complex. Production from the underground ore bodies, which are beneath and adjacent to the Grasberg open pit, are expected to ramp up over several years to around 240,000 tonnes a day.
