The Grasberg Mine is the world's largest gold mine and the third largest copper mine. The mine is primarily an open pit mine operation. It is located in the province of New Guinea in Indonesia near Puncak Jaya, the highest mountain in Papua. The Grasberg mine has over 19,000 employees.
To house and service the miners, a new town called "Tembagapura" was built. It included roads, a hospital, school, airstrip, power plant and other various needed infrastructure.
A book has been written about the mine: "Grasberg: Mining the Richest and Most Remote Deposit of Copper and Gold in the World, in the Mountains of Irian Jaya, Indonesia" by author George Mealey.
