Our Groote Eylandt Mining Company operation (GEMCO), located on an island in the Gulf of Carpentaria off the Australian coast, produces high-grade manganese ore.
Few other mines have a location quite like our Northern Territory manganese mine, on the island of Groote Eylandt, next to the pristine waters of the Gulf of Carpentaria in Australia’s north.
We have a long history on Groote Eylandt, with mining starting here more than half a century ago and a processing plant commissioned on the island not long after. Since then the plant has gone through several expansions, with the most recent one completed in 2013.
GEMCO is an open-cut mining operation, producing high-grade manganese ore that is shipped to our Tasmanian manganese alloy plant and around the world.
It is currently the largest and lowest-cost manganese ore producer in the world, which we hold a 60 per cent share in, with Anglo America Plc holding the remaining 40 per cent.

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 the genetic, neurodegerative disease Machado Joseph Disease (MJD) predicted to have some of the highest rates of people living with the disease on Groote Eylandt, than anywhere else in the world.
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.
We’re working with Traditional Owners to build a sustainable future.Read more
