QUARTERLY REPORT
June 2024
•   Achieved 98% of current Group FY24 copper equivalent production guidance [note 1], and remain on track to deliver FY24
    Operating unit costs in line with current guidance.

•   Delivered strong sales in the June 2024 quarter, capturing higher commodity prices and releasing working capital to finish the year.

•   Advanced our portfolio transformation, completing key milestones for the sale of Illawarra Metallurgical Coal [note 2], and
    progressing construction at Hermosa's Taylor zinc-lead-silver deposit as planned.

•   Aluminium production was largely unchanged year-on-year, as Hillside Aluminium achieved record production, Brazil Aluminium
    continued to ramp up, and Mozal Aluminium progressed its recovery plan.

•   Alumina production was largely unchanged year-on-year, with improved plant availability at Brazil Alumina partially offsetting a
    temporary bauxite conveyor outage at Worsley Alumina in the quarter.

•   Cannington payable zinc equivalent production [note 3] increased by 10% in FY24, despite adverse weather impacts, as the operation
    realised higher average metal grades.

•   Sierra Gorda payable copper equivalent production [note 4] declined by 15% in FY24, as higher plant throughput was offset by lower
    than planned copper grades and molybdenum recoveries in the current phase of the mine plan.

•   Cerro Matoso nickel production was largely unchanged year-on-year, with higher plant throughput and nickel grades supporting a 6%
    increase in quarterly production.

•   Consistent with guidance, Illawarra Metallurgical Coal saleable production decreased by 24% in FY24, as the operation completed
    planned longwall moves.

•   Australia Manganese progressed recovery plans following Tropical Cyclone Megan, while South Africa Manganese responded to
    stronger manganese prices, achieving record annual production.

•   FY25 production guidance revised lower for alumina (5%), Sierra Gorda payable copper equivalent (7%) and Cannington payable zinc
    equivalent (9%).

•   Impairment expenses for Worsley Alumina (~US$554M pre-tax) and Cerro Matoso (~US$264M pre-tax) will be recognised in our FY24
    financial results.


South32 Chief Executive Officer, Graham Kerr: "We delivered another quarter of improved operating performance, achieving sequentially
higher volumes across the majority of our operations, and remaining on track to achieve FY24 operating unit cost guidance.

"Our performance enabled us to capitalise on stronger commodity prices, lift sales volumes and release working capital, boosting cash
generation in the quarter.
"The sale of Illawarra Metallurgical Coal is expected to be completed later this quarter, further strengthening our balance sheet, simplifying
our business, reducing our capital intensity and unlocking capital to invest in our high-quality development projects in zinc and copper.

"Construction and permitting are tracking to plan at the Taylor zinc-lead-silver deposit at Hermosa, the first phase of a regional-scale
opportunity to supply commodities critical for the global energy transition."

CORPORATE UPDATE
Sustainability

•      We completed planned milestones in our multi-year Safety Improvement Program, deploying our 'Lead Safely Every Day' program
       across our leadership and frontline workforce.

•      We advanced decarbonisation programs to support our target [note 5] to halve our operational greenhouse gas (GHG) emissions by
       2035. In FY24, Worsley Alumina converted two coal-fired boilers to natural gas, expected to reduce the refinery's operational GHG
       emissions by over 10% from FY21 levels. Hillside Aluminium has now converted 36% of its pots to AP3XLE energy efficiency technology.

Portfolio

•      The sale of Illawarra Metallurgical Coal to an entity owned by Golden Energy and Resources Pte Ltd and M Resources Pty Ltd, for up to
       US$1,650M [note 6], received Australian Foreign Investment Review Board approval on 5 July 2024 [note 2]. The transaction is
       expected to complete in late Q1 FY25, subject to receipt of the remaining foreign merger clearances. As a result of the transaction, we
       will record an impairment reversal of ~US$200M (~US$140M post-tax) in our FY24 financial results, which will be excluded from FY24
       Underlying earnings.

•      The sale of our 50% interest in the Eagle Downs metallurgical coal project to a subsidiary of Stanmore Resources Limited is expected to
       complete in Q1 FY25. The consideration for the transaction comprises US$15M in cash, a contingent payment of US$20M [note 7] and
       a price-linked royalty of up to US$100M [note 8].

•      On 13 June 2024, Samancor Manganese entered into a binding agreement to divest the Metalloys manganese alloy smelter, subject to
       the satisfaction of conditions [note 9].

Income statement

•      We will record impairment expenses in our FY24 financial results, as set out below, which will be excluded from FY24 Underlying
       earnings.

        -     Worsley Alumina: ~US$554M (~US$389M post-tax) to a carrying value of ~US$2,027M, reflecting increased uncertainty created by
              the Western Australian Environmental Protection Authority's recommended conditions for the Worsley Mine Development
              Project approval and associated challenging operating conditions [note 10]; and

        -     Cerro Matoso: ~US$264M (~US$248M post-tax) to a carrying value of ~US$54M, reflecting structural changes in the nickel market
              which are expected to continue to place pressure on nickel prices and discounts for our ferronickel product.

•      Australia Manganese incurred ~US$90M of idle capacity and other remediation related costs as a result of Tropical Cyclone Megan.
       These costs will be excluded from FY24 Underlying earnings as an earnings adjustment.

•     FY24 Group Underlying depreciation and amortisation is expected to be ~US$915M, including ~US$140M for our manganese business
      and ~US$130M for Sierra Gorda.

•     FY24 Group Underlying net finance costs are expected to be ~US$250M, primarily comprising the unwinding of the discount applied to
      our closure and rehabilitation provisions and interest on lease liabilities and long-dated debt.

Cash flow and balance sheet

•     We delivered a strong sales result in the June 2024 quarter, drawing down inventory and capturing the benefit of higher commodity
      prices. This is expected to support an unwind of working capital of ~US$180M in H2 FY24 (H1 FY24: US$276M build).

•     We received net distributions [note 11] of US$26M from our manganese equity accounted investments (EAI) in FY24, as we provided
      US$30M of initial funding to Australia Manganese in the June 2024 quarter to support recovery plans.

•     We received net distributions [note 11] of US$27M from our Sierra Gorda EAI in FY24, including US$9M in the June 2024 quarter, as
      the operation invested in deferred stripping and study work for the fourth grinding line expansion.

•     FY24 Group capital expenditure (excluding EAIs and Hermosa) is expected to be ~US$670M, reflecting our planned investment in
      productivity and improvement projects across our portfolio, including ~US$340M at Illawarra Metallurgical Coal. Our share of capital
      expenditure for our manganese and Sierra Gorda EAIs is expected to be ~US$315M in FY24.

•     We returned US$198M to shareholders during FY24, including US$163M [note 12] in fully-franked ordinary dividends and US$35M via
      the on-market share buy-back [note 13].

Tax

•     Our FY24 Group Underlying effective tax rate (ETR) is expected to be in a range of approximately 40% to 42%, reflecting our
      geographical earnings mix and the corporate tax rates [note 14] and royalty related taxes [note 15] of the jurisdictions in which we
      operate.

•     We made Group tax payments of US$223M (excluding EAIs) in FY24 as cash tax normalised following one-off portfolio related tax
      payments in the prior period.

DEVELOPMENT AND EXPLORATION UPDATE
Hermosa project

•     We invested US$372M of growth capital expenditure at Hermosa in FY24, as we progressed construction of key infrastructure and
      permitting for the Taylor zinc-lead-silver and Clark battery-grade manganese deposits.

•     Following final investment approval for Taylor in Q3 FY24 [note 16], we completed pre-sink shaft activity and construction of the main
      shaft headframe during the quarter. Shaft construction is on track to commence in Q1 FY25.

•     We completed construction of the final two surface dewatering wells during the quarter, to support critical path dewatering activity for
      both the Taylor and Clark deposits.

•     Permitting activity continued to plan. During the quarter, we received an air permit from the Arizona Department of Environmental
      Quality, the last required state permit to enable full construction of Taylor.

•     FAST-41 federal permitting for both Taylor and Clark progressed to the next stage, with the US Forest Service publishing a Notice of
      Intent to prepare an Environmental Impact Statement during the quarter.

•     We advanced study and product qualification work for Clark. Construction of an exploration decline to provide access to ore to
      facilitate demonstration scale production remains on track to be completed by the end of CY25.

•     During the quarter, we were awarded a US$20M grant from the US Department of Defense under the Defense Production Act battery
      grant program to support development activity at Clark.

•     We directed US$24M to capitalised exploration during FY24 as we progressed drilling programs at our polymetallic Peake and Flux
      prospects [note 17]. Exploration results are expected across the 2024 calendar year.

Greenfield exploration

•     We invested US$27M in our greenfield exploration opportunities during FY24, as we progressed multiple exploration programs
      targeting base metals in Australia, USA, Canada, Argentina and Ireland.

Other exploration

•    We invested US$62M (US$48M capitalised) in exploration programs at our existing operations and development options during FY24,
     including US$24M at the Hermosa project (noted above, all capitalised) and US$13M for our Sierra Gorda EAI (all capitalised).

Worsley Alumina saleable production decreased by 2% (or 62kt) to 3,777kt in FY24, achieving 94% of guidance, as a temporary outage of
the bauxite conveyor impacted bauxite supply to the refinery during the June 2024 quarter. FY25 production guidance has been revised
lower by 6% to 3,750kt, as we complete additional conveyor maintenance, and manage bauxite inventories due to delays experienced with
regulatory approvals for new mining areas.

On 8 July 2024, the Western Australian Environmental Protection Authority (WA EPA) published its recommendation that the proposal for
the Worsley Mine Development Project may be implemented, subject to conditions. If imposed in their current form, several conditions
recommended by the WA EPA create significant operating challenges for Worsley Alumina and impact its long-term viability. Following what
has been a long and protracted process, Worsley Alumina intends to lodge an appeal in relation to the WA EPA assessment report, and to
work collaboratively with the Western Australian Government to enable Worsley Alumina to continue to meet the State's robust

Mozal Aluminium saleable production decreased by 9% (or 31kt) to 314kt in FY24, achieving 98% of guidance, with production increasing
by 8% during the June 2024 quarter as the smelter progressed its recovery plan, despite the impact of load-shedding. Production is
expected to increase by ~15% to 360kt [note 18] in FY25 (previously 372kt) as the smelter returns toward nameplate capacity.

Sales increased by 74% during the June 2024 quarter as we drew down inventory to normalised levels by the end of the financial year,
capitalising on strengthened market conditions.

As previously disclosed, we continue to work with the Government of the Republic of Mozambique and Eskom to secure the smelter's
hydro-electric power supply beyond Q3 FY26, as there are currently no viable alternative suppliers of renewable energy at the required
scale.

Sierra Gorda payable copper equivalent production [note 4] decreased by 15% (or 12.7kt) to 73.8kt in FY24, achieving 94% of guidance, due
to lower than planned copper grades in the June 2024 quarter.

Looking forward, higher clay content in the current phase of the mine plan is expected to continue to impact molybdenum production in
FY25, with FY25 payable copper equivalent production guidance revised lower by 7% to 85.3kt (copper 70.0kt, molybdenum 1.3kt, gold
25.0koz and silver 550koz).

Sierra Gorda continued to progress the feasibility study for the fourth grinding line expansion, which remains on track to support a final
investment decision in H1 FY25.

Cannington payable zinc equivalent production [note 3] increased by 10% (or 25.6kt) to 285.2kt in FY24 as the operation managed the
impact of widespread flooding following Tropical Cyclone Kirrily, and processed a sequence of higher grade stopes in the June 2024 quarter,
achieving 99% of guidance.

Looking forward, a significant increase in underground activity and complexity is expected to drive greater variability in mine performance
as the underground mine progresses towards the end of its life. Due to these factors and the need to re-establish run of mine stocks
following adverse weather impacts in H2 FY24, we have lowered FY25 guidance for mill throughput to 2,100kdmt and payable zinc
equivalent production by 9% to 250.1kt (silver 11,300koz, lead 100.0kt and zinc 50.0kt).

Higher sales volumes in the June 2024 quarter reflected timing differences following widespread flooding in the prior quarter that caused a
temporary outage of a third-party rail line.

Cerro Matoso payable nickel production was largely unchanged at 40.6kt in FY24, achieving 100% of guidance, with higher planned
throughput and nickel grades supporting a 6% increase in production during the June 2024 quarter. FY25 production guidance remains
unchanged at 35.0kt, reflecting lower planned nickel grades.

We continue to progress our strategic review of Cerro Matoso and expect to provide information on the outcomes of this review in H2
FY25.

NOTES
1.    Group payable copper equivalent production based on current FY24 production guidance, calculated by applying FY23 realised prices for all operations.

2.    Refer to market release "Illawarra Metallurgical Coal Sale Update" dated 5 July 2024.

3.    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, FY24 and FY24e.
4.    Payable copper equivalent production (kt) was calculated by aggregating revenues from copper, molybdenum, gold and silver, and dividing the total Revenue by the price of 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, FY24 and FY24e.
5.    Target is defined as an intended outcome in relation to which we have identified one or more pathways for delivery of that outcome, subject to certain assumptions or conditions. Our medium-
      term target is to halve our operational greenhouse gas (GHG) emissions by 2035 compared to our FY21 baseline. FY21 baseline adjusted to exclude GHG emissions from South Africa Energy Coal
      and TEMCO, which were divested in FY21.
6.    Refer to market release "Sale of Illawarra Metallurgical Coal" dated 29 February 2024.
7.    Subject to the Eagle Downs project reaching metallurgical coal production of 100,000 tonnes.

8.    Price-linked royalty calculated based on potential future metallurgical coal production and a metallurgical coal index price of at least US$170/t.

9.    Refer to media release "Agreement to divest Metalloys manganese alloy smelter" dated 13 June 2024.
10.   Refer to market release "Worsley Alumina Approvals Update" dated 22 July 2024.

11.   Net distributions from our material equity accounted investments (EAI) (manganese and Sierra Gorda) includes dividends, capital contributions and net repayments/drawdowns of shareholder
      loans, which are unaudited and should not be considered as an indication of or alternative to an IFRS measure of profitability, financial performance or liquidity.
12.   Comprised of US$145M in respect of the June 2023 half year paid in the December 2023 quarter and US$18M in respect of the December 2023 half year paid in the June 2024 quarter.

13.   We returned US$35M via the on-market share buy-back in FY24, purchasing 16M shares at an average price of A$3.37. Since inception, US$1.7B has been returned via the on-market share buy-
      back (795M shares at an average price of A$3.05 per share).
14.   The corporate tax rates of the geographies where the Group operates include: Australia 30%, South Africa 27%, Colombia 35%, Mozambique 0%, Brazil 34%, and Chile 27%. The Mozambique
      operations are subject to a royalty on revenues instead of income tax.
15.   Australia Manganese is subject to a royalty related tax equal to 20% of adjusted EBIT. Sierra Gorda is subject to a royalty related tax based on the amount of copper sold and the mining operating
      margin, the rate is between 5% and 14% for annual sales over 50kt of refined copper. These royalties are included in Underlying tax expense.
16.   Refer to market release "Final investment approval to develop Hermosa's Taylor deposit" dated 15 February 2024.

17.   Exploration Results and Exploration Targets: The information in this announcement that relates to the Exploration Results and Targets for Taylor, Clark, Peake and Flux is extracted from the market
      release "Final investment approval to develop Hermosa's Taylor deposit" dated 15 February 2024. The information was prepared by D Bertuch, Competent Person in accordance with the
