QUARTERLY REPORT
June 2022
c
• Group FY22 copper equivalent production[1] was 99% of current guidance, as the majority of our operations delivered to revised
plans, despite impacts from weather and labour availability caused by the COVID-19 pandemic
• We expect to report FY22 Operating unit costs in-line with our previously updated guidance at the majority of our operations, with
lower than anticipated producer currencies providing a benefit in the June 2022 quarter
• Our stable operating performance allowed us to capitalise on record conditions for a number of our commodities, with strong sales
in the June 2022 quarter capturing the benefit of high prices
• Worsley Alumina achieved record annual production in FY22, exceeding guidance and operating above nameplate capacity, as we realised
the benefit of embedded improvement initiatives
• Cannington beat our previously upgraded FY22 zinc equivalent production[2] guidance by 2%, successfully transitioning to a 100% truck
haulage operation in the June 2022 quarter
• Cerro Matoso achieved a 22% increase in payable nickel production, despite unplanned maintenance and
weather-related disruptions impacting the operation during H2 FY22
• Illawarra Metallurgical Coal successfully completed three longwall moves across Appin and Dendrobium during the year, with strong
price realisations for our premium quality hard coking coal supporting record pricing
• South Africa Manganese delivered record production in the June 2022 quarter as we increased our Manganese production by 22%,
supporting higher sales with customer demand for our premium products delivering strong price realisations
• We grew our share of aluminium production by 5% in the June 2022 quarter as we closed the acquisition of an additional shareholding
in the hydro-powered Mozal Aluminium smelter[3] and achieved first production from the restart of our 100% renewable powered
smelter in Brazil[4]
• We successfully completed the acquisition of Sierra Gorda[5] in H2 FY22, receiving our first US$68M in distributions from the joint venture
in June 2022
South32 Chief Executive Officer, Graham Kerr: “Our teams delivered another strong operating performance in the June quarter, despite
challenges that included extreme weather, supply chain disruptions and reduced labour availability caused by the COVID-19 pandemic. Record
annual production at Worsley Alumina, along with record quarterly production at South Africa Manganese and a strong sales result in June,
capturing the benefit of high prices, capped another year of substantial progress for South32.”
“We achieved further significant milestones as we reshape our portfolio towards the metals critical for a low carbon future. In May, we
completed the acquisition of an additional shareholding in the hydro-powered Mozal Aluminium smelter. We also completed our acquisition
of an additional interest in the MRN bauxite mine and delivered first production from the restart of our Brazil Aluminium smelter, powered
by 100 per cent cost efficient renewable power.
“Our strong financial position and capital management framework, which is designed to reward our shareholders as our financial
performance improves, supported further returns across the year via our on-market share buy-back, bringing total returns under our capital
management program to US$1.9 billion since its inception.”

CORPORATE UPDATE
• We expect to report FY22 Group Underlying depreciation and amortisation of US$790M, including US$110M
for our manganese business and US$60M for Sierra Gorda.
• We expect to report FY22 Group Underlying net finance costs of ~US$155M, which includes costs applicable to our ownership of a 45%
interest in Sierra Gorda and one-off costs associated with financing its acquisition.
• We received net distributions[6] of US$321M (South32 share) from our manganese and Sierra Gorda
equity accounted investments (EAI) in FY22. In the June 2022 quarter we received US$115M from our manganese business and our first
distribution of US$68M from Sierra Gorda.
• We spent US$128M purchasing a further 46M shares at an average price of A$3.89 per share via our
on-market share buy-back during FY22. As at 30 June 2022 our currently approved capital management program was 89% complete
with US$233M remaining to be returned to shareholders ahead of its extension or expiry on
2 September 2022[7]. We have now returned US$1.9B since the inception of our flexible capital management program, including
US$1.5B via our on-market share buy-back at an average price of A$2.93 per share, reducing total shares on issue by 13%.
• Our FY22 Group Underlying effective tax rate (ETR) is expected to be approximately 32%, reflecting the corporate tax rates of the
jurisdictions in which we operate[8], including our manganese and Sierra Gorda EAIs which are proportionally consolidated in our
Underlying results. The FY22 Underlying ETR for our manganese business is expected to be in a range of approximately 45 to 48%,
including the royalty related tax for Australia Manganese[9] and the derecognition of certain deferred tax assets.
• Further to the update provided in our March 2022 Quarterly Report on future tax payments following completion of the Sierra Gorda
acquisition, we now expect to make payments totalling ~US$150M in FY23[10].
Of this amount, ~US$130M is expected to be paid to the Dutch tax authorities to settle pre-closing tax liabilities ahead of potential
recovery from the vendors, with allocation of liability for such pre-closing tax liabilities being disputed.
• On 31 May 2022, we completed our acquisition of an additional 16.6% shareholding in Mozal Aluminium for a total cash consideration
of US$200M, increasing our ownership of the hydro-powered smelter to 63.7%[3].
• On 29 April 2022, we completed our acquisition of an additional 18.2% interest in the Mineração Rio do Norte (MRN) bauxite mine,
increasing our ownership to 33%[11], and further aligning our bauxite supply requirements within our aluminium value chain in Brazil.
• Following the end of the period, we completed the sale of four non-core base metals royalties to
Anglo Pacific Group Plc (Anglo Pacific) for a sale price of up to US$200M, including US$103M in cash payments[12], US$82M of Anglo
Pacific shares and contingent payments of up to US$15M[13]. We now hold a 16.9% interest in Anglo Pacific. We expect to recognise a
gain on sale of ~US$193M (~US$135M post-tax) within Other income in FY23, which will be excluded from Underlying earnings as an
earnings adjustment. We also expect to make tax payments associated with the transaction of ~US$58M across FY23.
• While no acceptable offers have been received to date, we continue to seek potential divestment opportunities for our interest in the
Eagle Downs Metallurgical Coal development option (Eagle Downs). Eagle Downs remains on care and maintenance, and we will assess
its carrying value as part of the annual impairment cycle for our FY22 financial results.
• We successfully concluded our release from a guarantee originally provided to support Seriti Resources Holdings Proprietary
Limited’s[14] acquisition of South Africa Energy Coal during the quarter. Following the derecognition of this commitment we expect to
recognise a ~US$12M benefit in Other income within our FY22 financial results.

DEVELOPMENT AND EXPLORATION UPDATE
Exploration plays a critical role within our simple strategy to identify and pursue opportunities to sustainably reshape our business for the
future, and create enduring social, environmental and economic value. We have established options to discover our next generation of
mines, with more than 25 exploration programs across our partnerships and own properties. Our expenditure has continued to increase in
this area as we have added further options and advance multiple, maturing exploration programs. In FY22 we spent US$56M across our
portfolio of greenfield and development options, an amount we expect to increase further to ~US$90M in FY23 as we continue to execute
on our strategy.
Hermosa project
• We continued to progress our feasibility study for the zinc-lead-silver Taylor Deposit at our Hermosa project in Arizona during the
quarter, ahead of a planned final investment decision in mid CY23. Following the decision by the United States Government to invoke
the Defense Production Act, supporting the production of critical minerals including manganese, we are looking at different options to
potentially accelerate the pre-feasibility study for the Clark Deposit.
• Construction of infrastructure to support our critical path dewatering of the Taylor orebody continued to plan during the quarter. Our
FY23 Growth capital expenditure guidance at Hermosa is US$290M as we continue our early works at Taylor ahead of a final investment
decision, and progress study work at Clark.
• We directed US$19M to our exploration programs at Hermosa during FY22, advancing the work to assess targets across a highly
prospective corridor including new exploration drilling at the Peake prospect[15] during the quarter.
Ambler Metals project
• During the quarter the right-of-way permits previously issued to the Alaska Industrial Development and Export Authority for the Ambler
Access Road were temporarily suspended to allow for additional work to be undertaken by United States government departments on
the Final Environmental Impact Statement. Together with our
Ambler Metals Joint Venture partner, we continue to assess the impact of this delay on our own study work for the Arctic Deposit.
• Separately we have commenced exploration activities at Ambler for the CY22 summer field season, including additional infill drilling of
the Arctic Deposit and drill testing of regional exploration targets in the Ambler Belt. The budget for the year is US$13M (South32 50%
share) with the program expected to support ongoing development study work being completed by the Joint Venture partners.
Greenfield exploration
• Consistent with our strategy of targeting prospective base metals regions, we entered into new farm-in agreements with Encounter
Resources Limited covering two copper and zinc exploration projects in the Northern Territory.
We will be the operator and fully fund initial exploration across both projects.
• We invested US$26M in greenfield exploration programs across our partnerships and own properties during FY22, with multiple drilling
and field programs targeting base metals currently underway in Australia, USA, Canada, Argentina, Peru and Ireland.
• Following the end of the period, we entered into a subscription agreement with Aldebaran Resources Inc.
(Aldebaran Resources) (TSX-V: ALDE) to acquire a 9.9% equity interest in the company for up to C$11.1M. Aldebaran Resources is an
exploration company whose key asset is an option to acquire a controlling interest in the Altar copper project in
San Juan, Argentina.
Brownfield exploration
• We directed US$48M (US$35M capitalised) towards exploration programs at our existing operations and development options during
FY22, including US$19M at the Hermosa project (noted above, all capitalised),
US$11M at Ambler Metals (all capitalised), US$2M for our manganese EAI (US$1M capitalised) and US$2M for our Sierra Gorda EAI
(US$1M capitalised).

MARKETING UPDATE
Our FY22 realised prices reflect the strong performance of our exchange traded commodities and notable positive realisations against indices
for our premium manganese and hard coking coal products. With heightened market volatility and supply chain disruptions prevalent across
our industry in H2 FY22, our stable operating performance enabled us to deliver production volumes largely to plan despite COVID-19 labour
and adverse weather-related disruptions in many of the geographies where we operate.
Innovative logistic solutions were established across multiple operations to mitigate the impact of ongoing port congestion, tight freight
markets and the broader disruption of global supply chains, contributing to our strong sales performance in the June 2022 quarter. This
enabled the Group to capitalise on strong markets lowering our inventory position by the end of the financial year with the working capital
benefit of this work expected to be realised in the first quarter of FY23.
The average realised prices achieved for our commodities are summarised below. Outstanding concentrate sales were revalued at 30 June
2022 with the final price of these to be determined in the December 2022 half year.

South32 Quarterly Report June 2022 Page 5 of 15
OPERATING UNIT COST UPDATE
We expect to report FY22 Operating unit costs in-line with our previously updated guidance at the majority of operations with lower than
anticipated producer currencies benefiting costs in the June 2022 quarter. Looking forward, higher volumes at some of our operations and
the tailwind of lower producer currencies are expected to provide partial relief from the ongoing effect of industry wide labour, raw material
and energy cost inflation that impacted our cost base in H2 FY22.
The cost profile of our Southern African aluminium smelters will continue to be heavily influenced by the South African rand, and the price
of raw materials and energy. H2 FY22 Operating unit costs are expected to be 15-20% higher than H1 FY22 (previously 10-15%), as both
smelters remained profitable by maintaining their strong operating performance which saw them continue to test their maximum technical
capacity, despite increased load-shedding.
The future direction of raw material and energy costs will also influence our non-operated Brazil Alumina refinery, where Operating unit
costs in H2 FY22 are expected to be ~15% higher than the first half of the financial year (US$262/t). The below commentary reflects our
expectations for FY22 Operating unit costs for all other operations. We will provide FY23 guidance with our financial results announcement
for the 30 June 2022 year end.

Alumina sales (kt) 4,004 3,974 (1%) 1,086 910 1,118 3% 23%
Worsley Alumina saleable production increased by 1% (or 28kt) to a record of 3,991kt in FY22 as the refinery delivered above its nameplate
capacity (4.6Mtpa, 100% basis), realising the benefit of embedded improvement initiatives and surpassing guidance expectations.
Sales increased by 23% in the June 2022 quarter with a carry-over shipment from the prior quarter supporting the refinery to draw inventory
levels down towards the end of the financial year. We realised an ~8% premium to the
Platts Alumina Index[26] on a volume weighted M-1 basis for alumina sales in FY22 as we continued to capture the impact of elevated global
freight rates in our realised prices (which are also reflected in our Operating unit costs).

Brazil Alumina saleable production decreased by 7% (or 101kt) to 1,297kt in FY22 as the refinery returned to nameplate capacity (3.86Mtpa,
100% basis) from October 2021, following an incident in July 2021 that damaged one of the two bauxite ship unloaders at the operation.
Despite the impact of local weather-related disruptions across H2 FY22, the refinery achieved 100% of FY22 production guidance.
Sales increased by 20% in the June 2022 quarter with a carry-over shipment from the prior quarter supporting the refinery to draw inventory
levels down towards the end of the financial year. We realised a ~5% premium to the
Platts Alumina Index[26] on a volume weighted M-1 basis for alumina sales in FY22 as we continued to capture the impact of elevated global
freight rates in our realised prices (which are also reflected in our Operating unit costs).
The refinery’s De-bottlenecking Phase Two project was approved for execution in the June 2022 quarter. The project is expected to increase
nameplate production rates by approximately 4% to 1.45Mt from H1 FY26, with anticipated capital expenditure of ~US$40M (South32 share)
between FY23 and FY25.

Brazil Aluminium saleable production was 0.3kt in FY22 with first production achieved in the June 2022 quarter following the successful
restart of the smelter. First sales to domestic customers were made in July 2022. With a slower than anticipated ramp-up associated with
the need to stabilise the electrolytic bath, we expect to provide updated FY23 production guidance with our FY22 results announcement,
including revised timing to achieve nameplate production (179ktpa, our 40% share).

Hillside Aluminium saleable production was largely unchanged at 714kt in FY22 as the smelter achieved 99% of guidance, despite the impact
of increased load-shedding. Our first pots utilising the AP3XLE energy efficiency technology were relined during the June 2022 quarter, with
the project expected to deliver both volume and energy efficiency benefits, reducing the smelter’s carbon intensity.
Sales increased by 11% in the June 2022 quarter with inventory returning to normalised levels as we realised the benefit of initiatives
undertaken to establish alternative discharge and cargo shipping options, mitigating poor third-party port performance and ongoing shipping
congestion.

Mozal Aluminium saleable production increased by 5% (or 13kt) to 278kt in FY22 with the smelter benefitting from our roll-out of the AP3XLE
energy efficiency technology, which partially offset the impact of increased load-shedding to achieve 99% of guidance. Our equity share of
production reflects the completion of our acquisition of an additional
16.6% shareholding in the smelter on 31 May 2022, taking our ownership to 63.7%. Prior period production and sales numbers have not
been restated for this change in ownership (presented on a 47.1% basis).
Aluminium sales increased by 33% in the June 2022 quarter supported by the improvement in quarterly production volumes and the

Payable copper sales (kt) – 27.7 N/A – 11.1 16.6 N/A 50%
Sierra Gorda payable copper equivalent production[17] was 29.5kt in FY22, following the completion of our acquisition on 22 February 2022,
achieving 95% of guidance due to lower than planned copper grades in the June 2022 quarter.
Looking forward, the plant de-bottlenecking project remains on-track to sustainably lift throughput by 6% to ~50Mtpa
(100% basis) by the December 2022 quarter. Accordingly, our FY23 production guidance (South32 share) of copper 71.8kt, molybdenum
1.5kt, gold 29.9koz and silver 582koz reflects the benefit of the higher expected plant throughput.

Cannington payable zinc equivalent production[2] decreased by 6% (or 19.7kt) to 299.3kt as we completed planned maintenance and built
run of mine stocks in the June 2022 quarter to support the operation’s transition to
100% truck haulage. Notwithstanding our prioritisation of activities to support the transition to trucking and the ongoing impact of COVID-
19 on workforce availability, the operation exceeded our previously upgraded zinc equivalent production guidance by 2% and our original
FY22 guidance by 8%.
Payable silver and lead sales increased by 19% and 11% respectively in the June 2022 quarter as we drew inventory down to normalised
levels by the end of the financial year, capturing the benefit of strong pricing.
The operation transitioned to 100% truck haulage in the June 2022 quarter. While the new configuration is expected to bring higher-grade
material forward in the mine plan at current throughput rates, FY23 volumes are expected to be skewed towards H2 FY23 as crushing
operations relocate from underground to surface.

Payable nickel sales (kt) 33.5 41.8 25% 10.3 9.8 11.9 16% 21%
Cerro Matoso payable nickel production increased by 22% (or 7.6kt) to 41.7kt in FY22 following a major furnace refurbishment completed in
FY21 and the addition of higher-grade ore from the Q&P pit, increasing average nickel grades by 6% (FY22: 1.73%; FY21: 1.63%). While the
operation only achieved 95% of our FY22 guidance as a result of unplanned maintenance and weather-related disruptions during H2 FY22,
we expect plant availability and performance to return to normalised levels in FY23 as these temporary impacts ease.
Our payable nickel sales increased by 21% in the June 2022 quarter with inventories returning to normalised levels as shipping performance
improved and the ferronickel market recovered from the disruption that was caused by a temporary spike in LME Nickel prices to previously
unseen levels. Our ferronickel product typically attracts a discount to the LME Nickel price index on a volume weighted M or M+1 basis,
widening to approximately 15% in the
June 2022 quarter (FY22: 7%; FY21: 10%). Looking forward, we expect discounts to remain elevated due to weakening global steel demand,
and the current relationship between ferronickel and nickel pig-iron pricing conditions.

Illawarra Metallurgical Coal saleable production decreased by 15% (or 1,136kt) to 6,509kt in FY22 as we completed
three longwall moves across Appin and Dendrobium during the year. We also stopped our opportunistic energy coal sales of low-margin coal
wash material.
Production volumes declined by 11% in the June 2022 quarter following adverse weather and COVID-19 related labour restrictions that also
impacted the operation’s ability to maintain budgeted development rates. Notwithstanding these disruptions and the volatility witnessed
across seaborne coal markets, our geographically diverse customer base supported a 29% increase in sales volumes in the quarter as we
drew down inventory, capturing the benefit of very strong index prices.

Manganese ore sales (kwmt) 3,621 3,372 (7%) 891 775 860 (3%) 11%
Australia Manganese saleable production decreased by 5% (or 166kwmt) to 3,363kwmt in FY22 as weather disruptions and COVID-19
workplace restrictions prevented the re-build of stockpiles ahead of the wet season, and contributed to adverse ore handling characteristics
that resulted in a lower yield at the primary concentrator during the year.
Notwithstanding these challenges in H1 FY22, saleable production increased by 4% in the June 2022 quarter and we exceeded our revised
FY22 guidance by 5% as the operation benefitted from improved weather conditions.
Our FY22 price realisations improved year-on-year as we took advantage of favourable market conditions, achieving the high grade 44%
manganese lump ore index[28] on a volume weighted M-1 basis, despite our low-cost PC02 circuit operating above its design capacity,
contributing 11% of total production (FY21: 10%).

South Africa Manganese saleable production was largely unchanged at 2,069kwmt in FY22 as we produced higher volumes of premium
material from our Mamatwan mine during the year, more than offsetting the impact of scheduled maintenance in the March 2022 quarter.
The operation delivered a strong finish to the year, with saleable production increasing by 60% to a record 625kwmt in the June 2022 quarter
following the prior period’s maintenance shut, beating our FY22 guidance by 3%.
Record production was matched by a 17% increase in sales for the June 2022 quarter following the partial improvement in third party rail
and port performance from the prior quarter. We continue to optimise our product mix to take advantage of favourable market conditions,
realising a premium of ~18% to the medium grade 37% manganese lump ore index[29] on a volume weighted M-1 basis across FY22.

NOTES
1. Group FY22 and current FY22e payable copper equivalent production for all operations. Payable copper equivalent production was calculated using FY22 realised prices for all
operations except for Brazil Aluminium which is based on FY22 average index price for aluminium.
2. 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. FY21
realised prices for zinc (US$2,357/t), lead (US$1,862/t) and silver (US$25.4/oz) have been used for FY21, FY22 and FY22e.
3. Refer to market release “South32 completes acquisition of additional shareholding in Mozal Aluminium” dated 31 May 2022.
4. Refer to market release “Restart of Brazil Aluminium using renewable power” dated 6 January 2022.
5. Refer to market release “South32 completes acquisition of 45% interest in Sierra Gorda copper mine” dated 22 February 2022.
6. Net distributions from our material equity accounted joint ventures (manganese and Sierra Gorda) includes net debt movements and dividends, which are unaudited and
should not be considered as an indication of or alternative to an IFRS measure of profitability, financial performance or liquidity.
7. Since inception, US$1.5B has been allocated to the on-market share buy-back (695M shares at an average price of A$2.93 per share)
and US$386M returned in the form of special dividends.
8. The corporate tax rates of the geographies where the Group operates include: Australia 30%, South Africa 28%, Colombia 35%, M ozambique 0%,
Brazil 34% and Chile 27%. The Colombian corporate tax rate increased to 35% from 1 January 2022. The South African corporate tax rate reduced to 27% from 1 July 2022.
The Mozambique operations are subject to a royalty on revenues instead of income tax. Sierra Gorda is subject to a mining 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.
9. Australia Manganese is subject to a royalty related tax equal to 20% of adjusted EBIT which is included in Underlying tax expense.
10. Approximately US$123M and US$28M is expected to be paid in H1 FY23 and H2 FY23 respectively. We expect to recognise this amount as a tax liability in our FY22 financial
results. There is no impact on the Income Statement.
11. The increase in ownership in MRN has triggered a change in accounting treatment with the investment accounted for using the equity method (formerly classified as an
investment in an equity instrument designated as fair value through other comprehensive income).
12. Refer to market release “South32 unlocks up to US$200M in value from non-core royalty sale” dated 12 July 2022. The cash payment comprises US$48M payable on
completion, and US$55M payable in six equal quarterly instalments over the next 18 months.
13. The contingent payment is triggered if the West Musgrave project achieves commercial production, and throughput and commodity price-related conditions are met prior to
an agreed expiry date.
14. Refer to the market announcement “South Africa Energy Coal divestment update” dated 1 April 2021. Purchaser includes Thabong Coal Proprietary Limited, a wholly-owned
subsidiary of Seriti and two trusts for the benefit of employees and communities.
15. Peake Prospect Exploration Target: The information in this announcement that relates to the Exploration Target for Peake Prospect is extracted from “Hermosa Project Update”
published on 17 January 2022 and is available to view on www.south32.net. The information was prepared by a Competent Person in accordance with the requirements of
the JORC Code. South32 confirms that it is not aware of any new information or data that materially affects the information included in the original market announcement.
South32 confirms that the form and context in which the Competent Person’s findings are presented have not been materially mo dified from the original market
announcement.
16. Production guidance for Hillside Aluminium and Mozal Aluminium does not assume any load-shedding impact on production.
17. FY22 and FY22e 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. FY21 index prices for copper (US$4.23/lb), molybdenum (US$15.7/lb), gold (US$1,796/oz) and silver (US$25.2/oz) have been used for FY22 and FY22e.
18. South Africa Manganese ore has been reported as a 54.6% interest (previously 60%) to reflect our 60% interest in the Metalloys manganese alloy smelter which is currently
on care and maintenance and aligning with our interest in Hotazel Manganese Mines (HMM). South32 has a 44.4% ownership interest in HMM. 26% of HMM is owned by a B-
BBEE consortium comprising Ntsimbintle Mining (9%), NCAB Resources (7%), Iziko Mining (5%) and HMM Education Trust (5%). The interests owned by NCAB Resources, Iziko
Mining and HMM Education Trust were acquired using vendor finance with the loans repayable via distributions attributable to these parties, pro rata to their share in HMM.
Until these loans are repaid, South32’s interest in HMM is accounted at 54.6%.
19. Realised prices are unaudited. Volumes and prices do not include any third party trading that may be undertaken independently of equity production. Realised sales price is
calculated as sales Revenue divided by sales volume unless otherwise stated.
20. Realised prices for Sierra Gorda are unaudited and net of treatment and refining charges.
21. Realised prices for Cannington are unaudited and net of treatment and refining charges.
22. Realised nickel sales prices are unaudited and inclusive of by-products.
23. Realised ore prices are unaudited and calculated as external sales Revenue less freight and marketing costs, divided by external sales volume.
24. Realised ore prices are unaudited and calculated as external sales Revenue less freight and marketing costs, divided by external sales volume. Manganese ore sales are
grossed-up to reflect a 54.6% accounting effective interest.
25. FY22 Operating unit cost guidance includes royalties (where appropriate) and the influence of exchange rates, and includes various assumptions for FY22, including: an alumina
price of US$399/t; an average blended coal price of US$382/t for Illawarra Metallurgical Coal; a manganese ore price of US$6.07/dmtu for 44% manganese product; a nickel
price of US$10.60/lb; a silver price of US$24.22/troy oz; a lead price of US$2,308/t
(gross of treatment and refining charges); a zinc price of US$3,461/t (gross of treatment and refining charges); an AUD:USD exchange rate of 0.73; a USD:ZAR exchange rate
of 15.06; a USD:COP exchange rate of 3,843; and a reference price for caustic soda; all of which reflected forward markets as at March 2022 or our internal expectations.
26. The sales volume weighted average of the Platts Alumina Index (FOB Australia) on the basis of a one month lag to published pricing (Month minus one or “M-1”) for Worsley
Alumina was US$379/t and Brazil Alumina was US$384/t in FY22.
27. Illawarra Metallurgical Coal sales are adjusted for moisture and will not reconcile directly to Illawarra Metallurgical Coal production.
28. The sales volume weighted average of the Metal Bulletin 44% manganese lump ore index (CIF Tianjin, China) on the basis of M-1 was US$6.00/dmtu in FY22.
29. The sales volume weighted average of the Metal Bulletin 37% manganese lump ore index (FOB Port Elizabeth, South Africa) on the basis of M-1 was US$3.33/dmtu in FY22.
