South32 Limited has reported a net cash generation of US$121 million during the March 2026 quarter, demonstrating solid operational performance despite a tragic fatality at Worsley Alumina and significant weather disruptions across multiple operations. The cash generation was achieved while the company invested US$158 million in growth capital expenditure at its Hermosa project, underscoring management’s confidence in both current operations and future development opportunities.
The quarter delivered mixed operational results across South32’s portfolio. Brazil Alumina achieved record year-to-date production with alumina output increasing 1 percent year-to-date, while Hillside Aluminium continued testing its maximum technical capacity to capitalise on higher aluminium prices. Sierra Gorda maintained production guidance despite wet weather impacts and delivered a record quarterly distribution of US$135 million to South32. Brazil Aluminium also finished the quarter with improved pot stability and output, tracking ahead of current guidance. These highlights were partially offset by revised guidance downward of 6 percent for Australia Manganese FY26 production due to elevated site water levels and impacts from wet season rainfall and Tropical Cyclone Narelle.
The company’s balance sheet position strengthened during the quarter, with net cash increasing to US$96 million from the prior period. This improvement came on the back of continued strength in aluminium and base metals markets. Management returned capital to shareholders with a fully-franked interim ordinary dividend of US$175 million paid after quarter-end, reflecting confidence in the company’s financial position and cash generation capability. The combination of operational cash generation and disciplined capital allocation demonstrates South32’s ability to simultaneously fund growth investments and deliver shareholder returns.
The Hermosa project reached a significant regulatory milestone with the issuance of the Final Environmental Impact Statement and Draft Record of Decision under the FAST-41 federal permitting process. This progression brings the Taylor zinc-lead-silver project closer to construction commencement. Management indicated it remains on track to complete an assessment of project milestones and capital expenditure during the upcoming June 2026 half year as additional underground and surface infrastructure packages are awarded. The project’s advancement is particularly relevant given South32’s stated strategic focus on increasing production of copper, zinc and silver.
Weather-related operational challenges remain a key management focus, particularly at Australia Manganese where water management continues to require active intervention. Cannington demonstrated resilience by mitigating impacts from significant floods in northwest Queensland and remaining on track to deliver production guidance with third-party rail access restored late in the quarter. Investors should monitor quarterly updates on water level management at Australia Manganese and progress on Hermosa’s regulatory approvals and capital planning assessment.
