The mine life of open pit mining is due to close in few next year. even though the Grasberg mine complex is still available to mining through underground mining. When they underground mine fully operated, it is expected to be the world largest underground mine.
In 2016, the mine produced more than one million ounces of gold, making it the fourth largest gold producer that year. The gold deposits on Mount Carstensz were first discovered by a Dutch geologist in 1936. After a new era in Indonesia, following the implementation of foreign investment laws in 1967, with the Grasberg mine opened officially in 1973.
In February 2017, however, Freeport McMoRan announced that it was temporarily halting mining operations at Grasberg – which is also the third largest copper mine in the world – following a failure to reach an agreement with the Indonesian government on long-term investment plans. Until now they are still negotiating with Indonesian government to take over 51% of share to Indonesian government.
2. South Deep mine near Johannesburg, South Africa

Honourable mention for largest gold mine
We include one honourable mention for Donlin gold mine. The mine located in Western Alaska, in the Yukon Kuskokwim region. This is one of the largest known, undeveloped gold deposits in the world. One from Top 5 gold mine in Alaska region. The probable reserves estimated at 33.8 million ounces of gold on the whole. Donlin gold, the mining company, is 50/50 joint venture between Barrick and Novagold.
Based on exploration results, the Donlin Gold project will be an environmentally sound, open-pit gold mine. Located about 10 miles from Crooked Creek Village. In brief, the project would process approximately 59,000 short tons of ore per day.
The Donlin Gold project would provide thousands of jobs during construction. The construction phase is estimated to take three to four years on the whole. Throughout the estimated overall 27+ year operational phase. There will be a lot of variety of positions and shift work will be available correspondingly.
Infrastructure plans call for a power-generation plant, water-treatment plant, access roads, housing, two ports, a natural-gas pipeline and an airstrip.
In the final analysis, Donlin Gold estimates that the proposed mine could produce an average at least of 1.3 million ounces of gold annually during operation. This production level then would make Donlin Gold one of the largest gold mines not only in Alaska but also in the world.
