QUARTERLY REPORT

September 2024

South32 Chief Executive Officer, Graham Kerr: "We were devastated by the loss of Mr José Luis Pérez, who was fatally injured in an incident at Cerro Matoso on 17 September and we express our sincere and deepest sympathies to his family, friends and colleagues.

"We remain committed to improving our safety performance. We continue to implement our Safety Improvement Program, which will help us to achieve a step change in our performance so that everyone goes home safe and well every day.

"We have maintained annual production guidance for all of our operations with a strong start to the year in aluminium and a 20 per cent uplift in copper equivalent volumes from Sierra Gorda.

"Completing the sale of Illawarra Metallurgical Coal is a major milestone in our portfolio transformation which has unlocked significant value and streamlined our business toward commodities critical for a low-carbon future.

"The sale has also lowered our sustaining capital intensity and strengthened our financial position, enabling us to self fund our growth in base metals and deliver returns to shareholders via our on-market share buy-back. 

"At Hermosa, construction of our large-scale, long-life Taylor zinc-lead-silver project is progressing as planned and we are continuing to unlock value across our broader land package.

"During the quarter, Hermosa was selected for a US$166 million award negotiation from the US Department of Energy, which recognises Clark's potential to supply battery-grade manganese for the emerging North American market.

"Our transformed portfolio, focused on copper, zinc and our aluminium value chain, leaves us well placed to capitalise on the global energy transition and stronger market conditions to start the year."              

·	Completed the sale of Illawarra Metallurgical Coal and received upfront cash proceeds of US$964M1.
·	Expanded our capital management program by US$200M and commenced our on-market share buy-back.
·	Maintained FY25 production guidance for all operations.
·	Aluminium production increased by 5% as Hillside Aluminium continued to test its maximum technical capacity, and low-carbon aluminium2 production from Brazil Aluminium and Mozal Aluminium increased by 12%.
·	Worsley Alumina saleable production declined by 7% as planned calciner maintenance was undertaken and we managed constrained bauxite supply. The Western Australian Environment Minister is expected to consider approval of new bauxite mining areas in December 2024, with Federal approvals expected shortly thereafter.
·	Brazil Alumina saleable production was largely unchanged as plant availability continued to improve. A preliminary environmental license for the MRN West Zone mine life extension project was issued during the September 2024 quarter.
·	Sierra Gorda payable copper equivalent production3 increased by 20% due to higher planned copper grades and a significant increase in molybdenum recoveries as a result of improved ore quality.
·	Cannington payable zinc equivalent production4 declined by 34% due to challenging ground conditions, resulting in the deferral of a higher grade stope to the December 2024 quarter.
·	South Africa Manganese production increased by 12% as the operation delivered strong mining performance and continued to sell secondary products to maximise margins.
·	Australia Manganese continued a substantial dewatering program and remains on track to resume production in the December 2024 quarter. Initial external insurance recoveries of US$100M (100% basis) were received during the quarter.
·	Continued construction of Hermosa's Taylor zinc-lead-silver project as planned. Clark was selected for a US$166M award negotiation from the US Department of Energy for a potential commercial-scale battery-grade manganese facility5.
·	Entered into a strategic alliance to explore for copper in the Kalahari copper belt in Namibia and an earn-in agreement for a zinc-lead-silver prospect in Nevada, USA.

WORSLEY ALUMINA (86% SHARE)

South32 share	YTD FY24	YTD FY25	YoY		1Q24	4Q24	1Q25	1Q25 vs 1Q24	1Q25 vs 4Q24
Alumina production (kt)	972	850	(13%)		972	916	850	(13%)	(7%)
Alumina sales (kt)	913	824	(10%)		913	974	824	(10%)	(15%)

Worsley Alumina saleable production decreased by 7% (or 66kt) to 850kt in the September 2024 quarter as planned calciner maintenance was undertaken, and we managed constrained bauxite supply due to delayed approvals for new mining areas. FY25 production guidance remains unchanged at 3,750kt with the refinery to convert excess hydrate stocks to calcined alumina across the remainder of the year.

Sales decreased by 15% in the September 2024 quarter due to lower product availability and the timing of shipments.  We realised a circa 8% discount to the Platts Alumina index¹⁵ on a volume weighted M-1 basis for alumina sales in the September 2024 quarter, which reflected market based prices with the exception of a legacy supply contract with Mozal Aluminium which is linked to the LME aluminium price.

On 8 July 2024, the Western Australian Environmental Protection Authority (WA EPA) published its recommendation that the Worsley Mine Development Project (the Project) be approved, subject to conditions. If imposed in their current form, several conditions would create significant operating challenges. We have lodged an appeal in relation to the WA EPA assessment report.

On 15 October 2024, the Western Australian State Government announced that it would defer regulation of greenhouse gas emissions to the Federal Government's Safeguard Mechanism. The change will remove policy inconsistencies that currently exist between the State and Federal Government with regard to greenhouse gas emissions, and is expected to be addressed as part of the appeals process for the Project.

We continue to work collaboratively with the Western Australian Government to enable Worsley Alumina to continue to meet the State's robust environmental standards. The Western Australian Environment Minister is expected to consider approval of the Project in December 2024, with required Federal approvals expected shortly thereafter.

BRAZIL ALUMINA (36% SHARE, NON-OPERATED)

South32 share	YTD FY24	YTD FY25	YoY		1Q24	4Q24	1Q25	1Q25 vs 1Q24	1Q25 vs 4Q24

Alumina sales (kt)	272	326	20%		272	358	326	20%	(9%)

Brazil Alumina saleable production was largely unchanged at 334kt in the September 2024 quarter as the refinery continued to benefit from improved plant availability. FY25 production guidance remains unchanged at 1,350kt.

A preliminary environmental license for MRN's West Zone project, which has the potential to extend the life of the bauxite mine by more than 20 years¹⁶, was issued during the September 2024 quarter. A final investment decision for an enabling transmission line to connect MRN to the Brazilian power grid is expected during the December 2024 quarter.

BRAZIL ALUMINIUM (40% SHARE, NON-OPERATED)

South32 share	YTD FY24	YTD FY25	YoY		1Q24	4Q24	1Q25	1Q25 vs 1Q24	1Q25 vs 4Q24
Aluminium production (kt)	24	30	25%		24	28	30	25%	7%
Aluminium sales (kt)	8	25	213%		8	30	25	213%	(17%)

Brazil Aluminium saleable production increased by 7% (or 2kt) to 30kt in the September 2024 quarter as the smelter continued to ramp-up all three potlines. FY25 production guidance remains unchanged at 130kt.

HILLSIDE ALUMINIUM (100% SHARE)

South32 share	YTD FY24	YTD FY25	YoY		1Q24	4Q24	1Q25	1Q25 vs 1Q24	1Q25 vs 4Q24

Aluminium sales (kt)	170	175	3%		170	184	175	3%	(5%)

Hillside Aluminium saleable production was unchanged at 180kt in the September 2024 quarter as the smelter continued to test its maximum technical capacity, despite the impact of load-shedding. FY25 production guidance remains unchanged at 720kt¹³.

MOZAL ALUMINIUM (63.7% SHARE)

South32 share	YTD FY24	YTD FY25	YoY		1Q24	4Q24	1Q25	1Q25 vs 1Q24	1Q25 vs 4Q24
Aluminium production (kt)	84	88	5%		84	77	88	5%	14%
Aluminium sales (kt)	77	86	12%		77	101	86	12%	(15%)

Mozal Aluminium saleable production increased by 14% (or 11kt) to 88kt in the September 2024 quarter as the smelter achieved improved process stability following completion of its operational recovery plan, despite the impact of load-shedding.  FY25 production guidance remains unchanged at 360kt¹³.

The smelter sources all of its alumina from our Worsley Alumina refinery with approximately 50% priced as a percentage of the LME aluminium index under a legacy contract and the remainder linked to the Platts Alumina index on a M-1 basis, with caps and floors that reset every calendar year. As a result, the smelter's cost of alumina was at a discount to the index in the September 2024 quarter.

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 (45% SHARE)

South32 share	YTD FY24	YTD FY25	YoY		1Q24	4Q24	1Q25	1Q25 vs 1Q24	1Q25 vs 4Q24

Payable zinc sales (kt)	13.9	12.6	(9%)		13.9	20.2	12.6	(9%)	(38%)

Cannington payable zinc equivalent production⁴ decreased by 34% (or 26.6kt) to 50.7kt in the September 2024 quarter, as the operation managed increased underground activity and complexity which is expected to continue to drive variability in quarterly performance.

Ore mined decreased by 24% during the September 2024 quarter as additional dewatering and ground rehabilitation was required to access stoping fronts. Average metal grades also declined as the processing of a higher grade stope was deferred to the December 2024 quarter.

FY25 production guidance remains unchanged at 265.4kt payable zinc equivalent (silver 11,300koz, lead 100.0kt, zinc 50.0kt), with dewatering completed in the September 2024 quarter expected to benefit underground performance and access to higher grade stopes across the remainder of the year.

CERRO MATOSO (99.9% SHARE)

Payable nickel sales (kt)	8.5	8.8	4%		8.5	12.1	8.8	4%	(27%)

Cerro Matoso payable nickel production decreased by 25% (or 2.9kt) to 8.6kt in the September 2024 quarter due to lower planned nickel grades. FY25 production guidance remains unchanged at 35.0kt.

Sales decreased by 27% during the September 2024 quarter due to lower product availability. The discount for our ferronickel product narrowed to ~14% to the LME Nickel Index¹⁷ (FY24: ~25% discount) in the September 2024 quarter, reflecting tighter global supply of class two nickel.

We continued to progress our strategic review of Cerro Matoso and expect to provide an update in the June 2025 half year.

AUSTRALIA MANGANESE (60% SHARE)
