Our operations

Located on the island of Groote Eylandt, in the Gulf of Carpentaria in Australia’s Northern Territory, Groote Eylandt Mining Company (GEMCO) is an open-cut, strip-mining operation that produces high grade manganese ore.

Close to export markets in Asia, the GEMCO mine is one of the largest manganese ore producers in the world.

South32 owns 60 per cent of GEMCO, with the remaining 40 per cent held by Anglo American Plc.

Partnering with communities

Partnering with communities

Groote Eylandt is home to the Anindilyakwa people, who are the Traditional Owners of the land. We have aligned our community investments with the Traditional Owners, working to improve opportunities for local people.

Education is a priority for people on the island so we are partnering with the Graham Polly Farmer Foundation to support school-aged children on Groote Eylandt to improve their literacy and numeracy skills.

The health of local people is also a major concern with Groote Eylandt predicted to have some of the highest rates of people living with Machado Joseph Disease (MJD), a genetic, neurodegenerative disease.

We have supported the MJD Foundation to improve quality of life for Indigenous Australians living with the disease. This has included new equipment and services like physiotherapy delivered ‘On Country’, aimed at slowing the disease’s progression.
