Grasberg mine in Papua contributed 15.96 percent to Freeport McMoran Inc.'s sales. The company's first-quarter 2017 financial report (traded on the FXC exchange) shows Grasberg mine revenue of US$534 million out of total sales of US$3.34 billion.
The largest portion of the US mining company's sales came from Rod & Refining, amounting to US$1.1 billion, or approximately one-third of total sales. The second largest contribution came from its South African mines, at US$752 million (Note: This figure likely contains a typographical error; it should probably be US$752 million, not billion).
Freeport operates three mining concessions: South Africa, Papua, and North America. Copper and gold mining in Grasberg is Freeport's second-largest operation after South Africa. Freeport's gold sales from Papua reached 177,000 troy ounces (ozs) out of a total of 182,000 ozs.
