The Australia Region comprises operations within Australia and South America. These operations mine or produce alumina, bauxite, metallurgical and energy coal, manganese, silver, lead, zinc and nickel.

In north-west Queensland we operate one of the world’s largest producing silver mines.

Our metallurgical coal operations in the southern coalfields of New South Wales, near the city of Wollongong, have been producing premium quality, hard coking coal for steelmaking, for 80 years.

Manganese operations include an open-cut mine in the Northern Territory, ranked as one of the world’s lowest-cost manganese ore producers, and a manganese alloy plant in Tasmania.

Our alumina operations in Western Australia include one of the largest and lowest-cost alumina refineries in the world and have been mining, refining and exporting alumina since 1984.

Our Colombian nickel mine and smelter is one of the largest nickel producers in the world and has been operating for more than 30 years.

Worsley Alumina (86 per cent interest) is an integrated bauxite mining and alumina refining operation located in Western Australia. Worsley Alumina’s export customers include South32’s Hillside and Mozal Aluminium smelters in southern Africa. Worsley Alumina is one of the largest and lowest-cost alumina refineries in the world.

Metallurgical Coal
Illawarra Metallurgical Coal (100 per cent interest) operates two underground metallurgical coal mines near Wollongong in New South Wales, Australia. Metallurgical coal is trucked to Port Kembla for distribution to domestic and international customers. 
Australia Manganese (60 per cent interest) comprises the GEMCO open-cut manganese mine and the TEMCO manganese alloy plant. GEMCO, which is located in the Northern Territory, is one of the world’s lowest-cost manganese ore producers. GEMCO exports its ore product through port facilities located only 16km from mining operations at Milner Bay. Using ore shipped from GEMCO, TEMCO produces high carbon ferromanganese (HCFeMn), silicomanganese (SiMn) and sinter. The majority of TEMCO’s alloy production is exported to customers in Asia and North America, with the balance of TEMCO’s production being sold to steel customers in Australia and New Zealand.
Cannington (100 per cent interest) is a silver, lead and zinc underground mine and concentrator operation located in north-west Queensland, about 200km south-east of Mount Isa, and is one of the world’s largest silver producing mines. Concentrate produced at Cannington is trucked to the Yurbi rail loading facility and then railed about 800km to the Port of Townsville for export.
Cerro Matoso (99.94 per cent interest) is an open-cut lateritic nickel mine and ferronickel smelter, located near Montelibano, in the Córdoba Department in northern Colombia, which produces high-purity, low-carbon ferronickel granules. Cerro Motoso is one of the largest nickel producers in the world. The product is transported approximately 260km by road to Cartagena.
