Largest gold deposit

The world’s largest single gold deposit is located around 60 km north of Timika on the western half of the island of New Guinea. It contains around 202,172 kg (6.5 million troy ounces) of provable and probable reserves of gold. Copper is the main resource at Grasberg with additional large reserves of silver. The deposit is being mined by both open-pit and underground operations, with the open-pit mine situated in the mountains at 4,300 m above sea level. The richness of the Grasberg deposit is due to its location on the boundary of the Indo-Australian and Pacific tectonic plates, which stimulated several metal-rich plutonic intrusions over geological history.
