Owned by Freeport McMoRan with a large sharing arrangement with Rio Tinto , this gold mine contains a deposit of over 106.2mn ounces of gold .

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 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 .
