The largest gold mine in the world is the Grasberg mine, located in the province of Papua in Indonesia. Operated by PT Freeport Indonesia, a subsidiary of the American mining company Freeport-McMoRan, the Grasberg mine is one of the largest copper and gold mines in terms of reserves and production.
The Grasberg mine complex consists of the Grasberg open-pit mine and the Deep Ore Zone (DOZ) underground mine. The open-pit mine, which began operations in 1990, is one of the largest man-made craters in the world, measuring approximately 4 kilometers in diameter and 1,200 meters deep. The underground mine, located beneath the open pit, accesses deeper ore reserves.
The Grasberg mine has estimated gold reserves of around 30 million ounces and is known for its high-grade gold and copper deposits. In addition to gold and copper, the mine also produces silver and other metals.
The Grasberg mine has been the subject of controversy due to environmental concerns, social issues, and conflicts over land rights with indigenous communities. Despite these challenges, the mine continues to operate as one of the world’s largest and most productive gold mines, contributing significantly to Indonesia’s economy and global gold production.
