WORSLEY MINE DEVELOPMENT PROJECT RECEIVES STATE APPROVAL

South32 Limited (ASX / LSE / JSE: S32; ADR: SOUHY) (South32) advises that the Western Australian Minister for Environment has approved the Worsley Mine Development Project (the Project)[1].

A copy of the Ministerial Statement is available at: https://www.epa.wa.gov.au/all-ministerial-statements.

We welcome this approval after an extensive environmental assessment, consultation and review process, which commenced in 2019.

The Project will enable access to bauxite to sustain production at Worsley Alumina, maintain its competitive position in the global alumina sector, and continue its significant contribution to the South West. Worsley Alumina is one of the largest employers in the region, supporting jobs for thousands of workers and contractors.

The supply of alumina from Worsley Alumina is a vital component in the production of aluminium, a commodity critical for the global energy transition. Worsley Alumina recently achieved certifications against the Aluminium Stewardship Initiative, which reinforces that the alumina produced at Worsley Alumina meets relevant global standards of responsible production.

The conditions of the approval reflect in all material respects the Minister's determination on the appeal outcome for the Project as outlined in our announcement released on 13 December 2024[2].

Overall, the conditions are a positive outcome for Worsley Alumina and represent an improved position compared to the Western Australian Environmental Protection Authority's assessment report published in July 2024.

Receipt of this State approval triggers the Federal approval process. We expect to receive Federal approval for the Project in early calendar year 2025.
