Grasberg Grasberg >

FCX is engaged in exploration and development, mining and milling of ore containing copper, gold and silver in the Grasberg minerals district in Indonesia. The Grasberg minerals district contains one of the world's largest copper and gold deposits, and is at the heart of a highly prospective minerals district, where ongoing exploration is providing opportunities to continue to add to our long-lived reserves.

PT Freeport Indonesia (PT-FI) operates under a Contract of Work (COW) with the Government of Indonesia, which allows us to conduct exploration, mining and production activities in the 24,700-acre Block A area, which is where all of PT-FI’s proven and probable mineral reserves and current mining operations are located. Under the COW, PT-FI also conducts exploration activities in the Block B area currently covering 502,000 acres.

The Grasberg minerals district has three operating mines: the open pit, the Deep Ore Zone underground mine and the Big Gossan underground mine.
PT-FI also has several projects in progress in the Grasberg minerals district related to the development of largescale, long-lived, high-grade underground ore bodies, including the Common Infrastructure project, the Grasberg Block Cave underground mine and the Deep Mill Level Zone ore body. In aggregate, these underground ore bodies are expected to ramp up over several years to process 240,000 metric tons of ore per day following the transition from the open pit.
