The brokerage expressed concerns over ongoing production issues, particularly citing lower grades at the Worsley Alumina and Sierra Gorda mines, which it expects to persist into fiscal year 2026.
Similarly, Macquarie Securities reduced its price target for South32 from AU$4.50 to AU$4.00 per share, citing heightened costs associated with the Worsley Alumina project. The brokerage also raised concerns about the environmental rehabilitation risks associated with Worsley's extensive "open" land holdings, which it views as less favorable compared to industry peers.
South32 has experienced a cumulative decline of 10.2% year-to-date as of the last close, reflecting broader market concerns and specific challenges within the mining sector. The company operates globally, with diversified interests in base metals, alumina, and coal, contributing to its exposure to various economic and regulatory factors influencing commodity markets.
