- South32 Limited is a globally diversified mining and metals company headquartered in Perth, Australia, founded in 2000. The company operates a broad portfolio of assets producing bauxite; alumina; aluminium; copper; silver; lead; zinc; nickel; metallurgical coal; manganese; and ferronickel products. Its operations span multiple countries, including Australia, Brazil, South Africa, Colombia, and the United States, as well as several joint ventures and exploration projects across regions such as Africa, North America, and South America.
South32's core operations include the production of alumina and aluminium through assets such as Worsley Alumina, Brazil Alumina, Hillside Aluminium, and Mozal Aluminium; copper mining and processing notably at its Sierra Gorda operation in Chile; manganese production in South Africa; and metallurgical coal mining. The company also has an active exploration portfolio with projects and joint ventures targeting copper, zinc, lead, silver, gold, and molybdenum across Alaska, Australia, the USA, Argentina, Namibia, Botswana, and other locations.
Recent major developments include the strategic divestment of its nickel refinery Cerro Matoso S.A. in Colombia to CoreX Holding BV, completed in late 2025, reflecting South32’s ongoing portfolio transformation amid changes in the nickel market. The company has also been in the process of selling its Illawarra Metallurgical Coal asset in Australia to a consortium led by Golden Energy and Resources and M Resources for approximately $1.65 billion, marking South32’s exit from the coal sector to focus on base metals critical to the low-carbon transition. Operationally, the company has reported increased production efficiency and growth at several key sites, including a 12% rise in copper equivalent output at Sierra Gorda and a 33% increase in manganese volumes in Australia.
Strategic partnerships include a digital transformation alliance with General Electric to enhance operational safety and productivity via advanced technology platforms. Additionally, South32 has formed exploration partnerships with companies like Noronex Ltd. to target large-scale copper deposits in Africa, further expanding its resource base in key commodities aligned with global energy transition demands.
Overall, South32 Limited focuses on mining and metals critical for a low-carbon future, leveraging a diversified asset portfolio and executing portfolio realignment through strategic divestments and targeted exploration initiatives across multiple continents.
