QUARTERLY REPORT December 2023
? | FY24 Group copper equivalent production guidance reduced by 3%1, reflecting revised guidance for Brazil Alumina, Mozal Aluminium and molybdenum output from Sierra Gorda. |
? | H1 FY24 Operating unit costs expected to be in line or below FY24 guidance for the majority of our operations. |
? | We are well positioned to capture the benefit of improved market conditions through expected production growth of 7%2 in H2 FY24 and our ongoing focus on cost efficiencies. |
? | Achieved record half year aluminium production, as Hillside Aluminium maintained its strong performance and Brazil Aluminium delivered an 8% increase in quarterly production. |
? | Cannington payable zinc equivalent production3 increased by 13% in the December 2023 half year, as we mined a higher-grade sequence of stopes during the quarter. |
? | Cerro Matoso payable nickel production improved by 20% in the quarter, following the completion of planned maintenance and a temporary reduction in third-party gas supply in the prior quarter. |
? | Sierra Gorda payable copper equivalent4 production decreased by 14% in the December 2023 half year, due to lower planned copper grades, and a temporary outage of the molybdenum plant. |
? | Illawarra Metallurgical Coal production decreased by 39% in the December 2023 half year, as we completed two planned longwall moves. FY24 guidance is unchanged with volumes remaining weighted to the second half. |
? | Manganese production decreased by 5% in the December 2023 half year, as lower yields impacted secondary production at Australia Manganese, and South Africa Manganese completed planned maintenance. |
? | Alumina production was largely unchanged as Worsley Alumina completed planned calciner maintenance, while we have lowered FY24 production guidance for Brazil Alumina by 7% due to third-party power outages and maintenance. |
? | FY24 production guidance for Mozal Aluminium lowered by 12%, as we reduced pots in operation to enable the smelter's recovery plan to be safely executed and deliver a sustained improvement in process stability. |
? | We continued our investment in critical path infrastructure for the Hermosa project and remain on track to make a final investment decision for the Taylor zinc-lead-silver deposit in the March 2024 quarter. |
South32 Chief Executive Officer, Graham Kerr: "In the December 2023 quarter, our production results were mixed. Highlights for the quarter included a 20 per cent increase in zinc and nickel and a 7 per cent increase in silver. We also delivered record aluminium production for the half, as Hillside Aluminium maintained its strong performance and Brazil Aluminium continued to ramp up. However, production from Brazil Alumina, Mozal Aluminium and molybdenum output from Sierra Gorda was below plan, with flow on impacts to annual production guidance.
"With some of our commodities facing headwinds in the half, we continued to focus on delivering cost efficiencies and expect first half Operating unit costs to be below or in line with guidance for the majority of our operations.
"As we enter the second half, strengthening market conditions for many of our commodities, our planned 7 per cent production growth and ongoing cost management focus, position us well to capture higher margins.
"We continued to invest to increase our exposure to commodities critical to a low-carbon future. At our Hermosa project, we progressed critical path infrastructure and remain on track to make a final investment decision for the Taylor zinc-lead-silver deposit in the March 2024 quarter. Sierra Gorda also continued work on the fourth grinding line expansion project, which has the potential to sustainably increase copper production."

Corporate Update
? | Supporting our commitment to deliver improved safety performance, we continued to implement our multi-year Safety Improvement Program. This program includes significant investment in safety leadership through our 'Lead Safely Every Day' training, which continued to be deployed across our frontline leadership during the quarter. |
? | We progressed a Group-wide review focused on delivering a reduction in expenditure in FY24 and FY25 through cost efficiencies and capital prioritisation. We expect to provide further detail on this as part of our updated Operating unit cost and capital expenditure guidance with our H1 FY24 financial results announcement. |
? | We expect to record a build in working capital of ~US$275M in H1 FY24. Trade receivables increased due to the timing of sales, and our high value aluminium inventory remained temporarily elevated as port congestion at Richards Bay impacted the timing of shipments from Hillside Aluminium. We expect to complete additional shipments from Hillside Aluminium and drawdown our aluminium inventory to normalised levels during the March 2024 quarter. |
? | We received net distributions5 of US$60M (South32 share) from our equity accounted investments (EAI) in H1 FY24 (US$42M from our manganese business and US$18M from Sierra Gorda), which reflected lower commodity prices and investment in projects to improve productivity and grow future production volumes. |
? | We allocated US$375M to safe and reliable, and improvement and life extension, capital expenditure6 (excluding EAIs) in H1 FY24. This included our planned investment to support Illawarra Metallurgical Coal's transition to a more efficient single longwall configuration at the Appin mine from FY25 and additional ventilation capacity to enable mining in Appin's Area 7 until at least 20397. |
? | We returned US$145M in fully-franked ordinary dividends in respect of H2 FY23 during the December 2023 quarter. |
? | We also returned US$35M via our on-market share buy-back in H1 FY24, purchasing a further 16M shares at an average price of A$3.37. To 31 December 2023, our US$2.4B capital management program was 96% complete with US$98M remaining to be returned ahead of its extension or expiry on 1 March 20248. |
? | We made Group tax payments of US$96M (excluding EAIs) in H1 FY24 as cash tax normalised following one-off portfolio related tax payments in the prior period. |
? | During the December 2023 quarter, we received an indemnity payment of US$48M from the vendors of our Sierra Gorda acquisition, following Chilean Mining Tax reforms that were enacted in August 2023. This amount was recognised as a receivable in our FY23 financial accounts. |
? | Our Underlying effective tax rate (ETR) largely reflects the corporate tax rates and royalty related taxes of the jurisdictions in which we operate operate9 and our geographical earnings mix, including our manganese and Sierra Gorda EAIs on a proportional consolidated basis (including royalty related taxes for Australia Manganese10 and Sierra Gorda11). The impact of permanent differences can have a disproportionate effect on our Underlying ETR when profit margins are compressed, or losses are incurred in specific jurisdictions. For this reason, an Underlying ETR of approximately 60% to 65% is now expected for H1 FY24. |
? | We expect to report H1 FY24 Group Underlying net finance costs of ~US$120M, reflecting the Group's balance sheet position during the period. |
Development and Exploration Update
Hermosa project
? | We invested US$188M of growth capital expenditure in H1 FY24 as we progressed construction of key infrastructure for our Taylor zinc-lead-silver and Clark battery-grade manganese deposits. |
? | The second water treatment plant was commissioned and made operational and a further two dewatering wells were completed. Dewatering is a critical path item that will enable access to both the Taylor and Clark deposits. |
? | We progressed the feasibility study and independent peer review for the Taylor deposit which remain on track to support a final investment decision in the March 2024 quarter. |
? | The FAST-4112 federal permitting process progressed to the next stage, with the US Forest Service issuing a completeness determination for our mine plan of operations for both the Taylor and Clark deposits. |
? | We directed US$14M to capitalised exploration in H1 FY24, commencing a first time exploration drilling program at the Flux prospect13, a priority target in our highly prospective regional land package. |
Greenfield exploration
? | We invested US$19M in our greenfield exploration opportunities in H1 FY24 with multiple exploration programs targeting base metals currently underway in Australia, USA, Canada, Argentina, and Ireland. |
? | We also invested US$8M to increase our interest in Aldebaran Resources Inc. (Aldebaran Resources) to 14.8%. Aldebaran Resources has an earn-in to acquire an 80% interest in the Altar copper project in San Juan, Argentina. |
Other exploration
? | We invested US$34M (US$27M capitalised) in exploration programs at our existing operations and development options in H1 FY24, including US$14M at the Hermosa project (noted above, all capitalised), and US$6M for our Sierra Gorda EAI (all capitalised). |

OPERATING UNIT COST UPDATE
We expect to report H1 FY24 Operating unit costs in line or below current FY24 guidance for the majority of our operations, with the benefit of cost efficiencies and lower raw material input prices. Looking forward, we remain focused on driving operating performance and further efficiencies to mitigate cost pressures. Further, Operating unit costs in H2 FY24 are expected to benefit from a planned 7% increase in Group production volumes2.
The below commentary reflects our current expectations for H1 FY24 Operating unit costs. We will report H1 FY24 Operating unit costs and provide updated FY24 guidance with our H1 FY24 financial results announcement.

Brazil Alumina saleable production decreased by 7% (or 51kt) to 640kt in the December 2023 half year. Following the recovery from the prior period's port infrastructure outages, the refinery was impacted by third-party power outages and unplanned maintenance. Due to these impacts and additional required maintenance, we have reduced FY24 production guidance by 7% to 1,300kt and FY25 production guidance by 5% to 1,350kt.
Sales increased by 38% in the December 2023 quarter with a carry-over shipment from the prior quarter supporting a drawdown in inventory.

Aluminium sales (kt) | 177 | 167 | (6%) | 90 | 77 | 90 | 0% | 17% |
Mozal Aluminium saleable production decreased by 9% (or 16kt) to 166kt in the December 2023 half year, as the smelter continued to implement its recovery plan following the fatal safety incident in the prior period, while managing the impact of elevated load-shedding.
The smelter progressed upgrades to the girder infrastructure during the December 2023 quarter, which resulted in an unplanned reduction in crane availability. We took the decision to reduce the number of pots in operation to enable the recovery plan to be safely executed and complete work designed to deliver a sustained improvement in process stability. As a result, approximately 73 pots (~13% of the total) were out of operation at the end of quarter, with these pots expected to be progressively returned to operation during the 2024 calendar year. FY24 production guidance has been reduced by 12% to 320kt14 to reflect the lower number of pots in operation. FY25 production guidance is currently unchanged at 372kt14.
During the December 2023 quarter, approximately 60% of production was below specification material, which attracts product discounts compared to our other LME-linked aluminium sales. Metal quality is expected to progressively improve to LME-grade quality during the June 2024 half year.

Sierra Gorda payable copper production decreased by 17% (or 6.3kt) to 31.6kt in the December 2023 half year as higher throughput delivered by the plant de-bottlenecking project, was more than offset by lower planned grades.
Payable molybdenum production decreased by 0.3kt to 0.1kt in the December 2023 quarter due to an unplanned outage of the molybdenum plant and low recoveries. The operation has commenced work to restore production, with higher output expected in the June 2024 quarter. As a result, FY24 molybdenum production guidance has been reduced to 0.8kt (from 2.5kt).
Sierra Gorda progressed the feasibility study for the fourth grinding line expansion during the December 2023 quarter. The feasibility study remains on track to support a planned final investment decision in the June 2024 half year.
