Kitco ranked the world's biggest gold mines by production in 2020. The ranking below was developed on the basis of 2020 (calendar year) production figures reported by companies and preliminary estimates for Muruntau. Gold output is in thousand ounces (koz).
The Muruntau mining complex, located in Uzbekistan and consisting of open-pit mine and heap leach operations, is estimated to have produced slightly more than 2 million ounces of gold in 2020. Operated by state-owned Navoi company, the mine is more than 3.3km long, 2.5km wide nearly 600m deep. Considering the stunning resource base, estimated in excess of 150 million ounces, Muruntau will likely keep its title as the world's biggest gold mine in the nearest future.
