South32 Shifts Focus to Copper as Aluminum Divestment Proceeds

Daley, who succeeded long-time chief Graham Kerr this week, emphasized that the company is prioritizing the stability of its existing assets and the complexities of the Alcoa transaction. While the miner remains open to future growth opportunities, any capital allocation will be weighed against the potential for increased shareholder returns. The divestment of bauxite and aluminum operations marks a strategic move to concentrate on high-margin commodities, with copper expected to contribute more than half of the company's earnings once the deal closes in early 2027.

Operations in the Americas will become the firm’s geographic anchor, though the idle Mozal aluminum smelter in Mozambique remains a lingering challenge. After failing to secure a viable electricity supply agreement, South32 is currently negotiating with state-owned partners in South Africa and Mozambique to offload its 64% stake in the facility. If those partners decline, the company intends to test the market for external buyers. Meanwhile, South32 continues to advance projects at the Sierra Gorda copper mine in Chile, positioning itself to capitalize on the supply constraints of critical industrial metals.
