Quarterly Report: September 2025
Summary by AI BETAClose X
QUARTERLY REPORT
September 2025
South32 Chief Executive Officer, Graham Kerr: "We delivered another period of strong operating performance as we continued our focus on safe and reliable operations.
"Production highlights included a 12 per cent increase in payable copper equivalent production at Sierra Gorda and a 33 per cent uplift in manganese volumes, as we successfully executed the operational recovery plan at Australia Manganese.
"Our financial position remains strong as we continued our investment in growth at Hermosa, supported by US$117 million in net distributions from our Sierra Gorda and manganese equity accounted investments during the quarter.
"At Hermosa, we continued critical path shaft sinking for our Taylor zinc-lead-silver project, while the exploration decline for the Clark battery-grade manganese deposit remains on track to be completed in the December 2025 quarter.
"In addition to Hermosa, we continue to advance a pipeline of high-quality base metals development and exploration options.
"We welcome the decision of the US Government to support the establishment of the Ambler Access Road. This is a key step in unlocking the potential of the Ambler Mining District, where we hold high-grade copper and zinc options.
"Looking ahead, we remain focused on maintaining our operating momentum and capitalising on strengthening market conditions in base metals."

CORPORATE UPDATE
|
· |
We continue to implement our global Safety Improvement Program, including investment in safety leadership through our LEAD Safely Every Day program, together with further simplification of our systems and improved effectiveness of controls. |
|
· |
In August 2025, we published our second Climate Change Action Plan (CCAP 2025), building on our inaugural Climate Change Action Plan 2022. Our CCAP 2025 outlines how we are positioning our portfolio for the energy transition, reducing our operational emissions, supporting emissions reduction across our value chain, and strengthening physical climate resilience. Our CCAP 2025 will be the subject of a non-binding advisory shareholder vote at our 2025 Annual General Meeting. |
|
· |
Net cash5 declined by US$59M to US$64M in the September 2025 quarter, as we continued our investment in growth at Hermosa, and experienced a temporary build in working capital of ~US$100M. The increase in working capital reflected higher finished goods inventories due to the timing of shipments, as well as payments accrued in the prior period. |
|
· |
We received net distributions6 of US$117M (South32 share) from our equity accounted investments (EAI) in the September 2025 quarter, with US$81M from Sierra Gorda and US$36M from our manganese business. We expect further distributions from both Sierra Gorda and our manganese business to add to cash generation in the December 2025 quarter. |
|
· |
Australia Manganese completed the insurance settlement related to the impacts of Tropical Cyclone Megan, with an additional US$153M (100% basis) in external insurance recoveries agreed during the September 2025 quarter. This brings the final approved external insurance recoveries to a total of US$503M (100% basis). |
|
· |
We invested US$82M in Group capital expenditure (excluding EAIs and Hermosa) during the September 2025 quarter. |
|
· |
We made Group tax payments (excluding EAIs) of US$50M during the September 2025 quarter. |
|
· |
We returned US$7M to shareholders via our on-market share buy-back in September 2025, purchasing 4M shares at an average price of A$2.63 per share. Our US$2.5B capital management program is 94% complete, with US$136M to be returned to shareholders ahead of its extension or expiry on 11 September 20267. |
|
· |
Following the end of the September 2025 quarter, we paid a fully-franked ordinary dividend of US$117M in respect of the June 2025 half year. |
DEVELOPMENT AND EXPLORATION UPDATE
Hermosa project
|
· |
We invested US$160M8 of growth capital expenditure at Hermosa during the September 2025 quarter, as we progressed construction of the Taylor zinc-lead-silver project and an exploration decline for the Clark battery-grade manganese deposit. In addition, lease payments for self generated power assets were US$12M during the September 2025 quarter. |
|
· |
At Taylor, we continued critical path shaft sinking for both the ventilation and main shafts. The ventilation shaft is expected to reach the first underground mining level during the December 2025 quarter, at which point we will commence lateral development and shaft station construction before resuming sinking. |
|
· |
Surface infrastructure construction also progressed, with initial foundation works for the primary mill in the process plant completed during the September 2025 quarter. Construction activity for the process plant is on track to increase across FY26. |
|
· |
Construction of the exploration decline for Clark remains on track to be completed in the December 2025 quarter. |
|
· |
We invested US$6M in capitalised exploration during the September 2025 quarter as we continued exploration drilling at the Peake copper deposit. Concept studies are progressing on the potential to develop Peake, leveraging the infrastructure established for Taylor. |
Ambler Metals project
|
· |
On 6 October 2025, the President of the United States approved the appeal by the Alaska Industrial Development and Export Authority directing his Administration to issue authorisations necessary for the establishment of the Ambler Access Road9. The Ambler Access Road is a key enabler in unlocking the value of the Ambler Mining District, where we hold high-grade copper and zinc options through our 50% interest in the Ambler Metals joint venture and our 100% interest in the Roosevelt exploration project. |
|
· |
Separately, the US Government has agreed to acquire an initial ~10% equity interest in Trilogy Metals Inc. (Trilogy) 10, our 50% joint venture partner in Ambler Metals, to support exploration and development activities. As part of this investment, we have agreed to sell ~8.2M shares in Trilogy for cash consideration of ~US$17.8M and to issue a 10-year call option for an additional ~6.2M Trilogy shares held by South32, exercisable only following construction of the Ambler Access Road. Proceeds from the initial share sale will be reinvested into exploration and development at Ambler Metals. On completion of the initial investment, we will retain ~10.4M shares in Trilogy, representing a ~6% equity interest. |
Greenfield exploration
|
· |
We invested US$7M in our greenfield exploration opportunities during the September 2025 quarter as we progressed multiple exploration programs targeting base metals in highly prospective regions. |
|
· |
We expanded our pipeline of base metals exploration options through strategic alliances with Orogen Royalties Inc. targeting projects in western North America, and Aurum Discovery Limited, focusing on early stage prospects in Norway and Ireland. |
Other exploration
|
· |
We invested US$13M (US$9M capitalised) in exploration programs at our existing operations and development options during the September 2025 quarter, including US$6M at the Hermosa project (noted above, all capitalised), US$3M for our Sierra Gorda EAI (US$2M capitalised) and US$2M for our manganese EAI (nil capitalised). |

Mozal Aluminium saleable production increased by 3% (or 3kt) to 93kt in the September 2025 quarter, as the smelter operated near its maximum technical capacity, prior to our decision in August 2025 to stop pot relining due to the uncertainty of future electricity supply beyond March 20261. FY26 production guidance remains unchanged at 240kt4, based on operations continuing to March 2026, when the current electricity supply agreement expires.
We are continuing to actively engage with the Government of the Republic of Mozambique, Hidroeléctrica de Cahora Bassa (HCB) and Eskom on securing sufficient and affordable electricity for Mozal Aluminium. Despite our efforts, negotiations have not progressed to provide confidence that Mozal Aluminium will secure sufficient and affordable electricity supply beyond March 2026. Without the required electricity supply, we expect that Mozal Aluminium will be placed on care and maintenance at the end of the current agreement.
