It is mostly owned by Freeport-McMoRan (FCX), which owns 90.64% of PT Freeport Indonesia (PT-FI), the principal operating subsidiary in Indonesia, including 9.36% owned through its wholly owned subsidiary, PT Indocopper Investama. The government of Indonesia owns the remaining 9.36% of PT Freeport Indonesia.

FCX operates under a Contract of Work (CoW) agreement with the government of Indonesia, which allows Freeport to conduct exploration, mining and production activities in a 27,400-acre area (Block A). It also conducts exploration activities in a 413,000-acre area (Block B). All of Freeport's proven and probable mineral reserves and current mining operations are located in Block A. The mine has three mining operations: the open pit, the Deep Ore Zone underground mine, and the Big Gossan underground mine. A fourth, the Deep Mill Level Zone, is being developed.The 2016 production was 1,063,000,000 pounds (482,000,000 kg) of copper, 1,061,000 ounces (30,100,000 g) of gold; and in 2016 sales of 2,900,000 ounces (82,000,000 g) of silver.

In August 2017, FCX announced that it will divest its ownership in PT-FI so that Indonesia owns 51%. In return the CoW will be replaced by a special license (IUPK) with mining rights to 2041 and FCX will build a new smelter by 2022.
