QUARTERLY REPORT
September 2023
• FY24 production guidance remains unchanged across all operations.
• Manganese ore production increased by 4%, with a quarterly record at South Africa Manganese
and a strong start to the year at Australia Manganese.
• Alumina production increased by 3%, as Brazil Alumina recovered from temporary port infrastructure outages,
while Worsley Alumina completed planned calciner maintenance.
• Hillside Aluminium continued to test its maximum technical capacity and low-carbon aluminium1 production
from Brazil Aluminium and Mozal Aluminium increased by 2%.
• Illawarra Metallurgical Coal production decreased by 33%, as the operation commenced an extended planned longwall move at the
Dendrobium mine. A new industrial agreement covering deputies at the Appin mine was finalised subsequent to the end of the quarter.
• Sierra Gorda payable copper production decreased by 8%, as higher throughput delivered by the plant
de-bottlenecking project was offset by lower planned copper grades.
• Cannington payable zinc equivalent production decreased by 6%, due to lower planned zinc grades in the quarter,
with the operation remaining on-track to deliver 11% production growth in FY24.
• Cerro Matoso payable nickel production decreased by 19%, as the operation was impacted by planned plant maintenance and a
temporary disruption to gas supply.
• We commenced federal permitting at our Hermosa project under FAST-41 and remain on-track to complete the feasibility study
for the Taylor zinc-lead-silver deposit in Q2 FY24.
South32 Chief Executive Officer, Graham Kerr: “We have maintained annual production guidance for all of our operations with a strong start
to the year at our manganese operations, a 34 per cent increase in production at
Brazil Alumina and continued growth in low-carbon aluminium volumes.
“With macroeconomic conditions creating headwinds for many of our commodities, we remain focused on driving operating performance
and cost efficiencies. This focus, along with our production growth in commodities critical for
a low-carbon future, positions us well to capture higher margins as market conditions improve.
“Our disciplined approach to capital management allowed us to return a further US$22 million with the continuation of our US$2.4 billion
capital management program, and following the end of the period, pay our US$145 million
fully-franked ordinary dividend in respect of the prior six months.
“During the quarter, we continued to advance our portfolio of high-quality growth options in critical commodities.
At our Hermosa project, we commenced federal permitting for the Taylor and Clark deposits under FAST-41 and remain on-track to complete
Taylor’s feasibility study in the December 2023 quarter.”

CORPORATE UPDATE
• Supporting our commitment to deliver improved safety performance, we continued to implement
our multi-year Safety Improvement Program, including significant investment in safety leadership through our
‘Lead Safely Every Day’ training.
• We remain focused on driving cost performance to mitigate industry-wide inflationary pressure. During the quarter, we initiated a
Group-wide review that is expected to deliver a reduction in expenditure across our operations and functions in FY24 and FY25.
• Net debt2 increased by US$299M to US$782M during the September 2023 quarter with lower commodity prices,
and a temporary build in working capital of ~US$250M as we made payments accrued in the prior period
and our high value aluminium inventory increased by ~US$100M. We expect to lower our aluminium inventory position to normalised
levels during the December 2023 quarter, as Brazil Aluminium makes its first planned export sales and we drawdown inventory in our
Southern African value chain.
• We invested in productivity and improvement activities across our portfolio, allocating US$180M to
safe and reliable, and improvement and life extension, capital expenditure3. 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 20394.
• We received net distributions5 of US$33M (South32 share) from our equity accounted investments (EAI) during the September 2023
quarter, including US$15M from our manganese business and US$18M from Sierra Gorda.
• We allocated US$22M to our on-market share buy-back during the September 2023 quarter, purchasing a further 10M shares at an
average price of A$3.34 per share. Our US$2.4B capital management program is 95% complete with US$112M remaining to be returned
ahead of its extension or expiry on 1 March 20246.
• Subsequent to the end of the quarter, we paid a fully-franked ordinary dividend of US$145M in respect of the
June 2023 half year.
• Our FY24 Underlying effective tax rate (ETR) is expected to reflect the corporate tax rates and earnings of the jurisdictions in which we
operate7, including our manganese business and Sierra Gorda on a proportional consolidated basis (including royalty related taxes for
Australia Manganese and Sierra Gorda).
The impact of permanent differences can have a disproportionate effect on our Underlying ETR when profit margins are compressed.
• Separately, the Group made tax payments of US$39M (excluding EAIs) during the September 2023 quarter,
as cash tax normalised following one-off portfolio related tax payments in the prior period.
DEVELOPMENT AND EXPLORATION UPDATE
Hermosa project
• We invested US$71M of growth capital expenditure as we progressed construction of key infrastructure and commenced federal
permitting for our Taylor zinc-lead-silver and Clark battery-grade manganese deposits.
• We expect to complete the feasibility study and an independent peer review for the Taylor deposit in the
December 2023 quarter and announce the study results and a final investment decision in the March 2024 quarter.
• We commissioned the second water treatment plant, a key milestone in our critical path dewatering activity,
and are on-track to commence construction of the Clark exploration decline in the December 2023 quarter.
• We submitted a mine plan of operations for both the Taylor and Clark deposits with the US Forest Service, commencing the federal
permitting process under FAST-418.
• We directed US$6M to capitalised exploration during the September 2023 quarter, as we continued exploration drilling at our copper-
lead-zinc-silver Peake prospect, to follow-up recent high-grade copper exploration results9.
Greenfield exploration
• We invested US$9M in our greenfield exploration opportunities during the September 2023 quarter, including a
first time exploration drilling program at our 100% owned Roosevelt project in Alaska.
• Consistent with our focus on adding prospective base metals options, we acquired an additional 4.9% equity interest in Aldebaran
Resources Inc. (Aldebaran Resources) for approximately US$8M, taking our ownership 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
South32 Quarterly Report September 2023 Page 2 of 13
• We invested US$15M (US$11M capitalised) in exploration programs at our existing operations and development options during the
September 2023 quarter, including US$6M at the Hermosa project (noted above, all capitalised), US$1M at Ambler Metals (all
capitalised) and US$2M for our Sierra Gorda EAI (all capitalised).

copper. FY23 realised prices for copper (US$3.51/lb), molybdenum (US$21.28/lb), gold (US$1,821/oz) and silver (US$21.9/oz) have been used for FY23, Q1 FY24 and FY24e.
12. Payable zinc equivalent production (kt) was calculated by aggregating revenues from payable silver, lead and zinc, and dividing the total Revenue by the price of zinc. FY23
realised prices for zinc (US$2,151/t), lead (US$1,919/t) and silver (US$21.1/oz) have been used for FY23, Q1 FY24 and FY24e.
13. The first boiler conversion is expected to reduce the refinery’s operational greenhouse gas emissions by up to ~205,000 tonnes per annum
or ~6% from FY23 levels.
14. Our realised price for nickel sales during the September 2023 quarter was US$6.19/lb, which represented a ~33% discount to the average
LME Nickel index price of US$9.23/lb.
15. Illawarra Metallurgical Coal sales are adjusted for moisture and will not reconcile directly to Illawarra Metallurgical Coal production.
16. The sales volume weighted average of the Metal Bulletin 44% manganese lump ore index (CIF Tianjin, China) on the basis of a one-month lag to published pricing (Month
