In 1939, a Dutch geologist filed a report on the Ertsberg, Dutch for ‘ore mountain’, in Indonesia, which later prompted Freeport mining company to develop what is today the world’s largest gold mine and the third-largest copper mine, near Papua’s highest Puncak Jaya mountain. The picture shows dump trucks winding their way through hairpin bends in the expansive Grasberg copper and gold opencast mine near Timika, where 19 500 people work at an operation owned 90.64% by Freeport-McMoRan of the US and 9.36% by the Indonesian government. Four crushers and two semi-autogenous mills produce a copper-gold slurry that is piped 112 km to the port of Amamapare, where it is filtered and dried for shipping to smelters around the world.
