There is a unique massive quarry in Indonesia too. The Grasberg Mine is one of the largest gold, silver and copper reserves, located near Puncak Jaya mountain range. The mine employes 19500 people and remains the world leader in output of copper, gold and silver.
The Grasberg is the world’s highest quarry, this significantly complicates the process of its development. It is only recently that the production has fully been developed with the assistance of modern technology. Nowadays, ownership belongs to Freeport McMoran corporation.
If the level of expected output remains the same, the large-scale production in Indonesia will certainly not stop in the next 30 years. Using modern technology processes more than 85000 tons of ore daily, and about 30 million tonnes of valuable species within a year. The supplies of precious metals in the Grasberg quarry are really large. At present, the Grasberg mine is the largest gold and the third largest copper mine in the world.
