Each metallogenic epoch introduced its own deposit type(s), of which porphyry copper (and related skarn), followed by sediment-hosted stratiform copper and then iron oxide copper-gold (IOCG), are globally preeminent. Nonetheless, genesis of the copper provinces remains somewhat enigmatic and a topic of ongoing debate.
The Grasberg porphyry copper-gold deposit is located in the Ertsberg-Grasberg mineral district in the province of Papua, Indonesia and lies within the New Guinea fold-and-thrust belt (Fig. 1a).Grasberg is the world's largest gold-rich porphyry copper deposit and its mineral district also contains a number of large mineralized copper-gold skarns (Cooke et al. 2005).

Grasberg Mine: Gold Mine in the Clouds: With Mark Hamill. At 14,000 feet, in the remote jungles of New Guinea is the largest gold and copper deposit in the world. Getting to that deposit and building a profitable mine was one of the biggest engineering challenges ever.

The Grasberg ore bodies contain very high combined copper-gold grades, especially when considering the size of production. As ore ex-traction from the open pit will be soon uneconomic due to the increased strip, production will continue to move underground with block caved ore from the Grasberg Block Cave (GBC), and
Chalcopyrite-bornite veins account for the bulk of the copper and gold in the Grasberg deposit. The spatial distribution of the ore metals is shown in detail in Fig. 4 of Leys et al. (2012) . Pollard et al. (2005) group the major episode of chalcopyrite-bornite mineralisation at Grasberg with the anhydrite-quartz veins and molybdenite veins ...
The Grasberg mine operated by Freeport McMoRan and jointly owned by Freeport and Rio Tinto is one of the largest mining clusters on the globe. The mine is located in the very remote highlands of the Sudirman mountain range in the province of Papua, Indonesia.

Gold abundances in porphyry copper deposits vary greatly, complicating efforts to define gold-rich porphyry copper deposits. The original definition was based on the Au/Mo ratios of porphyry copper deposits with no reference to their copper content, and resulted in the suggestion that gold-rich deposits were found largely in island arc regions (Kesler, 1973).
Grasberg mine has the single largest known gold reserve and the second largest copper reserves in the world. It is located 96km north of Timika, at Tembagapura in Irian Jaya – the most easterly of Indonesia's provinces – on the western half of …
PT-FI began open-pit mining of the Grasberg ore body in 1990. The final phase of the Grasberg open pit was mined during 2019, including the removal of the open pit ramps. In aggregate, the Grasberg open pit produced over 27 billion pounds of copper and 46 million ounces of gold in the 30-year period from 1990 through 2019.
