Ounces of Gold Produced

The Gosowong processing plant comprises a primary jaw crusher followed by a SAG and ball mill circuit and a recently completed Vertimill circuit. The ore then undergoes a conventional cyanide leaching process.

Gold and silver is then recovered from the cyanide solution using the Merrill-Crowe zinc precipitation process and is smelted to produce gold doré. Gold and silver doré produced at Gosowong is refined in Jakarta.

Sustainability and community

Newcrest creates economic value for Indonesia and local communities in a number of ways, including direct revenues from PTNHM’s operations, investment in public infrastructure and services, support of local suppliers and a range of indirect economic benefits. 

Gosowong is a major contributor to the local economy with a workforce of around 2,000. More than 98 per cent of Gosowong’s total workforce are Indonesian.

PTNHM invests extensively in community initiatives through its Corporate Social Responsibility program to share the benefits of mining, support community needs and strengthen socio-economic development in the region.

PTNHM’s commitment to the local economy is further demonstrated by implementing a policy of preferring locally based suppliers, where possible.
