South32 has agreed to sell most of its aluminium assets to Alcoa for an implied enterprise value of up to US$5.6 billion, as the company shifts its focus toward copper and higher-margin base metals. Separately, its Sierra Gorda copper joint venture in Chile approved a US$725 million fourth grinding line expansion, expected to lift processing capacity by around 25% from 2027 to 2030.
