GEMCO

On Groote Eylandt there lived a "Gecko" called Ipilya who was 100 yards long. His appearance was much like that of Kulta and he was reputed to live in the Numarika swamp. The Aborigines associated him with thunder and the monsoonal rain because of this fearsome creature's voice.

Our History

North Groote Eylandt Aerial View
Groote Eylandt was first discovered by Dutch explorers in 1624. Manganese was first noted in 1803, then again later in 1907 by a government geologist. In 1962, BHP geologist Bill Smith recognised manganese outcrops as a potentially continuous and major ore bearing structure. BHP launched an extensive four year exploration program, and in 1964, GEMCO was formed with special mining leases negotiated and granted by the Anglican Church Mission Society, the Commonwealth Government, and traditional Aboriginal land owners.

1966 saw the first shipment of ore loaded from Milner Bay, destined for smelting at TEMCO, GEMCO’s sister company in Tasmania. Six months later, in response to growing worldwide demand, the first international export shipment left for Japan.

Continuous improvements throughout GEMCO’s history has enabled increased production, beneficiation and export, introduction of new products, and quality accreditation.

Sustainable management of our resource and the talents of our people will ensure our contined success.
