WORSLEY ALUMINA APPROVALS UPDATE
South32 Limited (ASX / LSE / JSE: S32; ADR: SOUHY) (South32) provides the following update regarding approvals for the Worsley
Mine Development Project (Project), our mine life extension project at Worsley Alumina.
As previously announced, the Western Australian Environmental Protection Authority (WA EPA) recommended the Project be
approved, subject to conditions1.
Worsley Alumina subsequently lodged an appeal in relation to the WA EPA assessment report, as several proposed conditions would
create significant operating challenges, and went beyond reasonable measures for managing environmental risks based on scientific
assessment and decades of operating experience.
On 12 December 2024, the Western Australian Minister for Environment determined the appeal outcome for the Project.
We are pleased to advise that the Minister has determined after considering available information, that the EPA's assessment and
overall conclusion that the Project may be implemented, subject to conditions, is reasonable.
Further, the Minister has agreed with the Appeals Committee's recommendations to amend specific conditions based on the
arguments presented during the appeals process, including by Worsley Alumina.
A copy of the Minister's determination and the Appeals Committee report to the Minister is available at:
https://www.wa.gov.au/organisation/office-of-the-appeals-convenor.
The Minister's determination is a positive outcome for Worsley Alumina.
In particular, it is consistent with the Western Australian Government's Greenhouse Gas Emissions Policy for Major Projects2, with
greenhouse gas emissions to be regulated in accordance with the Commonwealth Government Safeguard Mechanism and
unnecessary duplication between Commonwealth and State regulation removed.
A detailed assessment of other conditions referred to in the Minister's determination is underway.
State approval of the Project through a Ministerial Statement from the Western Australian Minister for Environment is expected later
this month.
Federal approval is expected in early calendar year 2025.
