Grasberg gold mine, Indonesia
Production: 1.061 million ounces
Located in Indonesia, the Grasberg gold mine is one of the largest gold mine in the world and the third largest copper mine, with a total of 19,500 workers. In addition, it is an open-pit mine, which is the largest known single gold deposit in the world.
Grasberg has three operating mines-Grasberg open-pit mine, deep mine zone (DOZ) underground mine and Big Gossan underground mine.
Copper was first discovered in 1936, and gold in 1988. As one of the top 10 biggest gold mines in the world, the open-pit mine is 2.5 miles (approximately 4 kilometers) wide, and there are also large-scale underground mining activities in the area.
The open-pit mine has been mined since 1990, but it is also currently facing difficulties. Freeport currently has a dispute with the Indonesian government over the terms of the mining contract. This has also led to thousands of employees facing layoffs and departures. Glasberg is making every effort to ease the tension, but it is still facing cost reductions and slowing down in its future development.
Cortez gold mine
Production: 1.06 million ounces
The Cortez Gold Mine is also part of the Barrick Gold Company and is located in Nevada.

Lihir Gold Mine, Papua New Guinea
Production: 991,000 ounces
Lihir, one of the biggest gold mines in the world, is located on a tropical island in Papua New Guinea, in an extinct volcanic crater. It was put into production in 1997, with a total output of more than 10 million ounces.
