Quarterly Report: December 2024
QUARTERLY REPORT
December 2024
South32 Chief Executive Officer, Graham Kerr: "We continued our strong start to the year, maintaining production guidance for all of our operations except Mozal Aluminium, as we continue to mitigate the impact of civil unrest in Mozambique.
"We achieved strong results in the December 2024 quarter, delivering higher base metals production and increasing alumina production by 14 per cent, capturing the benefit of strong alumina prices.
"We returned US$169M to shareholders, paying fully-franked ordinary dividends in respect of the prior six months and continuing our on-market share buy-back, leaving US$171M to be returned to shareholders under our capital management program.
"Having successfully divested Illawarra Metallurgical Coal in the September 2024 quarter, we have a strong balance sheet and platform for growth in minerals and metals critical to the world's energy transition.
"At Hermosa, construction of the zinc-lead-silver Taylor deposit reached a significant milestone as we commenced shaft sinking in the quarter. We also progressed development of an exploration decline at the Clark battery-grade manganese deposit and exploration drilling at the Peake copper deposit to unlock further value across our broader land package.
"We also continued to strengthen our growth pipeline, embedding additional copper exploration options in highly prospective regions during the period."

CORPORATE UPDATE
Safety
|
· |
We remain united by our belief that everyone can go home safe and well every day. We continued to implement our multi-year Safety Improvement Program during the December 2024 half year. This includes our investment in safety leadership through our LEAD Safely Every Day program which is being extended to frontline employees, contractors that perform high-risk work at our operations, and functional roles that support them. |
|
· |
On 17 September 2024, Mr José Luis Pérez was fatally injured in an incident at Cerro Matoso. Our deepest sympathies remain with Mr Pérez's family and colleagues to whom we are continuing to provide support. The incident occurred while Mr Pérez was at Cerro Matoso to perform a scaffold maintenance task. An investigation into the incident was completed during the December 2024 quarter and we are engaging with the relevant authorities. Key learnings from the incident have been shared across our organisation, and improvement actions are underway. |
Financial
|
· |
We delivered improved sales performance in our aluminium value chain in the December 2024 quarter, increasing quarterly sales volumes of alumina and aluminium by 16% and 10%, respectively, and drawing down inventory. The timing of sales and higher commodity prices resulted in a temporary increase in trade receivables and contributed to a build in working capital of ~US$120M in the December 2024 quarter (H1 FY25: total build of ~US$270M). |
|
· |
We invested ~US$210M in Group capital expenditure (excluding equity accounted investments (EAI) and Hermosa) in H1 FY25, including US$57M at Illawarra Metallurgical Coal prior to its divestment on 29 August 20247. |
|
· |
We received net distributions8 of US$86M (South32 share) from our Sierra Gorda EAI in H1 FY25, including US$54M in the December 2024 quarter. |
|
· |
No funding was provided to Australia Manganese in the December 2024 quarter (September 2024 quarter: US$63M), as a further US$150M (100% basis) of external insurance claims were approved in the quarter (H1 FY25: US$250M, 100% basis). We are continuing to work with our insurers to assess the timing and value of further recoveries in relation to the impact of Tropical Cyclone Megan. |
|
· |
We incurred idle capacity and remediation related costs at Australia Manganese of ~US$75M (60% basis) in H1 FY25, which will be excluded from Underlying earnings as an earnings adjustment. |
|
· |
We returned US$140M in fully-franked ordinary dividends in respect of H2 FY24 during the December 2024 quarter. |
|
· |
We also returned US$29M via our on-market share buy-back in H1 FY25, purchasing 12M shares at an average price of A$3.64 per share, leaving US$171M remaining to be returned to shareholders ahead of extension or expiry of the program on 12 September 20259. |
|
· |
We made Group tax payments (excluding EAIs) of US$116M in H1 FY25. Our H1 FY25 Group Underlying effective tax rate (ETR) is expected to be ~35%, reflecting our geographical earnings mix and the corporate tax rates10 and royalty related taxes11 of the jurisdictions in which we operate. |
DEVELOPMENT AND EXPLORATION UPDATE
Hermosa project
|
· |
We invested ~US$250M of growth capital expenditure at Hermosa in H1 FY25, as we progressed construction of the Taylor zinc-lead-silver project and an exploration decline for the Clark battery-grade manganese deposit. |
|
· |
Construction of Taylor progressed as planned in the December 2024 quarter, as we commissioned the hoisting system for the ventilation shaft and commenced sinking. Earthworks for the processing plant site were also completed in the quarter, with construction activity for the processing plant scheduled to increase across the second half of FY25. |
|
· |
We directed US$16M to capitalised exploration in H1 FY25 as we continued to test the potential for a continuous copper system connecting the Peake copper deposit and Taylor Deeps. |
Greenfield exploration
|
· |
We invested US$18M in our greenfield exploration opportunities in H1 FY25 as we progressed multiple exploration programs targeting base metals in Australia, USA, Canada, Argentina, Namibia and Ireland. |
|
· |
We acquired a 19.9% interest in American Eagle Gold Corp. (AEG) for US$21M in the December 2024 quarter6. AEG holds an option to acquire a 100% interest in the Nakinilerak exploration prospect, located within the Babine copper-gold porphyry district in British Columbia, Canada. |
Other exploration
|
· |
We invested US$31M (US$26M capitalised) in exploration programs at our existing operations and development options in H1 FY25, including US$16M at the Hermosa project (noted above, all capitalised), US$7M for our Sierra Gorda EAI (all capitalised) and US$3M for our manganese EAI (nil capitalised). |

OPERATING UNIT COST UPDATE
While we achieved a number of strong production results and realised improved commodity prices in H1 FY25 that are expected to increase Group operating margins, compared to the prior period, our Operating unit costs in H1 FY25 are expected to reflect the impact of higher raw material input costs in our aluminium value chain. Looking forward, our Operating unit costs in H2 FY25 are expected to benefit from weaker producer currencies.
The below commentary reflects our current expectations for H1 FY25 Operating unit costs. We will report H1 FY25 Operating unit costs and provide updated FY25 guidance with our H1 FY25 results announcement.

Worsley Alumina saleable production decreased by 4% (or 84kt) to 1,850kt in the December 2024 half year, primarily due to constrained bauxite supply as a result of delayed approvals for new mining areas. Production improved by 18% (or 150kt) in the December 2024 quarter following the completion of planned calciner maintenance in the September 2024 quarter. FY25 production guidance remains unchanged at 3,750kt. Further planned calciner maintenance is scheduled for the March 2025 quarter.
Sales increased by 17% in the December 2024 quarter due to improved product availability. We realised a ~11% discount to the Platts Alumina index19 for alumina sales in the December 2024 half year, which reflected market based prices except for a legacy supply contract with Mozal Aluminium which is linked to the LME aluminium price.
On 20 December 2024, the Western Australian Minister for Environment approved the Worsley Mine Development Project3 (the Project), subject to conditions. We remain on track to receive Federal approval for the Project in the March 2025 quarter.

During the December 2024 quarter, the joint venture partners of MRN made a final investment decision to construct a transmission line to connect the MRN bauxite mine to the Brazilian power grid. The transmission line will enable MRN to reduce operating costs by replacing its diesel-powered generation with cost efficient renewable energy sources, and support the future development of the West Zone mine life extension project. Our share of capital expenditure for the transmission line is expected to be ~US$70M (33% share) over FY25 to FY27.

Mozal Aluminium saleable production increased by 7% (or 12kt) to 178kt in the December 2024 half year as the smelter approached nameplate capacity following completion of its operational recovery plan, despite the impact of load-shedding.
In December 2024, the transport of raw materials to the smelter was disrupted by road blockages due to civil unrest in Mozambique1. We subsequently reduced amperage to the potlines20, reducing aluminium production capacity by approximately 3%, to preserve raw materials and maintain operational stability.
In recent weeks, we have re-built alumina stocks at the smelter as we successfully implemented contingency plans and road blockages eased. While Mozal Aluminium has continued to operate and export aluminium to customers during this period, any escalation in civil unrest has the potential to impact our critical trucking activity and operations. Accordingly, production guidance remains withdrawn as we monitor and respond to the evolving situation.
As previously disclosed, we continue to work with Eskom and the Government of the Republic of Mozambique to extend the smelter's hydro-electric power supply beyond March 2026, as there are currently no viable alternative suppliers of renewable energy at the required scale.

Sierra Gorda payable copper equivalent production4 increased by 21% (or 8.0kt) to 46.4kt in the December 2024 half year, with higher planned copper grades and a significant increase in molybdenum recoveries due to improved ore quality. FY25 production guidance remains unchanged at 84.8kt payable copper equivalent (copper 70.0kt, molybdenum 1.3kt, gold 25.0koz and silver 550koz).
Sierra Gorda continued additional engineering and study work for the fourth grinding line expansion during the December 2024 quarter. A feasibility study and final investment decision by the joint venture partners is expected in the second half of calendar year 2025.

Cannington payable zinc equivalent production5 decreased by 17% (or 26.4kt) to 129.9kt in the December 2024 half year as the operation continued to manage increased underground activity and complexity. Ore mined and plant throughput increased by 28% and 23%, respectively, in the December 2024 quarter, following the completion of additional dewatering in the prior quarter. This improved plant throughput, together with higher planned lead and silver grades, supported a 56% increase in payable zinc equivalent production in the December 2024 quarter.
FY25 production guidance remains unchanged at 265.4kt payable zinc equivalent (silver 11,300koz, lead 100.0kt and zinc 50.0kt).

Australia Manganese continued to implement its operational recovery plan following the impacts of Tropical Cyclone Megan in the March 2024 quarter.
We continued a substantial dewatering program which has enabled access to certain mining pits and a phased restart of mining activities. We resumed production from the primary concentrator as planned in the December 2024 quarter with saleable production of 639kwmt. FY25 production guidance remains unchanged at 1,000kwmt, with production expected to continue at limited rates in the second half of FY25 as we progress the recovery plan and complete further dewatering.
Construction of a critical bridge that connects the northern pits of the Western Leases mining area and the processing plant progressed as planned in the December 2024 quarter and remains on track to be completed in the March 2025 quarter.
During the December 2024 quarter, we progressed the demolition of undersea structures, and commenced installing the pilings for the new wharf. While we have experienced some weather related delays, a second jack-up barge has arrived on site and is expected to improve the productivity of the pilings installation.
Subject to further potential impacts from the wet season, export sales are expected to progressively increase over the June 2025 quarter.
