South32 Ltd. reported a strong operating performance for the September 2025 quarter, highlighted by a 12% increase in payable copper equivalent production at its Sierra Gorda operation and a 33% rise in manganese volumes, following the successful execution of an operational recovery plan at Australia Manganese. The company continued to invest in growth at its Hermosa project, with critical shaft sinking underway for the Taylor zinc-lead-silver project and exploration decline for the Clark battery-grade manganese deposit on track for completion in the December 2025 quarter. South32's financial position remains robust, supported by US$117 million in net distributions from its Sierra Gorda and manganese equity accounted investments during the quarter.
