by power and raw material inputs, given the operation's high variable cost base. Mozal Aluminium utilises hydroelectric
power that is generated by Hidroeléctrica de Cahora Bassa (HCB). HCB delivers power into the South African grid to Eskom
and Mozal Aluminium sources electricity via the Mozambique Transmission Company (Motraco) under a long term contract. The
price of electricity supplied is South African rand based with the rate of escalation linked to a South Africa domestic
production price index plus margin. 
 
Financial performance 
 
Underlying EBIT increased by 140% (or US$35M) in H1 FY18 to US$60M as a 25% increase in the average realised price of
aluminium (+US$65M) and higher sales volumes (+US$23M) were partially offset by higher alumina, pitch and coke input costs
(-US$20M). 
 
Capital expenditure 
 
Sustaining capital expenditure increased to US$8M in H1 FY18. The US$18M AP3XLE energy efficiency project, which was
approved in August 2017, remains on schedule with first incremental production anticipated in FY20 and the full benefit to
be realised by FY24. The project will deliver a circa 5% (or 10kt pa) increase in annual production with no associated
increase in power consumption.

Brazil ALUMINA (ALUMINA 36% SHARE, ALUMINIUM 40% SHARE) 
 
Volumes 
 
Brazil Alumina saleable production increased by 3kt to 676kt in H1 FY18 as the refinery continued to operate at capacity. 
 
FY18 production guidance remains unchanged at 1.3Mt with Phase I of the refinery de-bottlenecking project nearing
completion. 
 
Operating costs 
 
Operating unit costs at the non-operated refinery increased by 21% to US$234/t in H1 FY18 as the price of caustic soda
increased and consumption rates rose temporarily as lower quality bauxite feed was introduced following a weather related
disruption to supply from MRN. 
 
Financial performance 
 
Alumina Underlying EBIT increased by 392% (or US$47M) in H1 FY18 to US$59M as a 44% increase in the average realised price
of alumina (+US$73M) was partially offset by higher caustic soda (-US$9M) and fuel oil (-US$12M) costs. 
 
Aluminium Underlying EBIT decreased by US$10M to a loss of US$12M as our obligation to purchase electricity from
Eletronorte was fulfilled during the period, following termination of the contract in December 2015. The sale of surplus
electricity generated other income of US$36M, although this was more than offset by the utilisation of the associated
onerous contract provision and the recognition of a US$12M provision to reflect transmission charges that will no longer be
offset by ongoing electricity purchases. 
 
Capital expenditure 
 
Sustaining capital expenditure decreased to US$10M in H1 FY18 with the de-bottlenecking Phase I project nearing
completion.

(a)    H1 FY17 reflects balance as at 30 June 2017. 
 
South Africa Energy Coal (92% SHARE) 
 
Volumes 
 
South Africa Energy Coal saleable production decreased by 9% (or 1.4Mt) to 13.4Mt in H1 FY18. Export coal production
exceeded expectations as productivity lifted at both the Klipspruit mine and the export oriented areas of the WMC. In
contrast, domestic production was impacted by a reduction in demand from the Duvha power station and scheduled maintenance
in the domestically focused areas of the WMC. The continued build of inventory across H1 FY18 reflects ongoing constraint
in the supply chain and weather related delays at the Richards Bay Coal Terminal. 
 
FY18 production guidance remains unchanged at 27.5Mt (11.5Mt export; 16.0Mt domestic). 
 
Operating costs 
 
Operating unit costs increased by 38% to US$36/t in H1 FY18 as the South African rand strengthened, the proportion of
higher margin export tonnes (with associated washing and logistics costs) increased and an area of in-pit inventory at the
WMC was written down to net realisable value. 
 
We have updated FY18 unit cost guidance to US$34/t to reflect revised exchange rate and price assumptions. Exchange rate
and price assumptions for FY18 unit cost guidance are detailed in footnote 20. 
 
Financial performance 
 
Underlying EBIT decreased by 10% (or US$13M) in H1 FY18 to US$115M. Higher average export (+US$77M) and domestic (+US$28M)
realised prices were more than offset by lower sales volumes (-US$30M), an increase in planned maintenance and labour costs
(-US$48M), inflation (-US$22M) and a stronger South African rand (-US$21M). The operation's costs were also impacted by the
net realisable value write-down of an area of in-pit inventory at the WMC (-US$8M). 
 
Capital expenditure 
 
Sustaining capital expenditure increased to US$68M in H1 FY18 as activity previously deferred as a result of adverse
weather was completed. Sustaining capital expenditure will continue to be directed towards the WMC in H2 FY18 given the
requirement to open-up new mining areas. FY18 guidance for Sustaining capital expenditure has been increased by US$20M to
US$132M. 
 
We also invested US$4M in H1 FY18 to progress the 4.3B South African rand KPSX project, which was approved by the Board in
November 2017. The 8Mtpa brownfield project will extend the life of the Klipspruit colliery by more than 20 years.

Illawarra Metallurgical Coal (100%) 
 
Volumes 
 
Illawarra Metallurgical Coal saleable production decreased by 50% (or 1.9Mt) to 1.9Mt in H1 FY18 as the Appin colliery
recovered from an extended outage and the Dendrobium longwall progressed through a faulted zone. 
 
FY18 production guidance of 4.5Mt remains unchanged with a longwall move now scheduled for Dendrobium in the June 2018
quarter. 
 
Operating costs 
 
Operating unit costs increased by 99% to US$149/t in H1 FY18, commensurate with the significant reduction in coal sales. 
 
We have updated FY18 unit cost guidance to US$135/t to reflect revised exchange rate and price assumptions. Exchange rate
and price assumptions for FY18 unit cost guidance in footnote 20. 
 
Financial performance 
 
Underlying EBIT decreased by US$193M in H1 FY18 to a loss of US$84M as lower sales volumes (-US$258M) more than offset
higher average realised coal prices (+US$36M), lower price-linked royalties (+US$15M) and a volume related reduction in
depreciation (+US$14M). 
 
Capital expenditure 
 
Sustaining capital expenditure decreased by 17% to US$40M in H1 FY18 as underground development was impacted by the
extended outage. FY18 guidance for Sustaining capital expenditure has been reduced by a further US$15M to US$105M to
reflect a lower level of underground activity.

Australia Manganese (60% SHARE) 
 
Volumes 
 
Australia Manganese saleable ore production increased by 13% (or 202kwmt) to a record 1.7Mwmt in H1 FY18. Lower than
expected rainfall in the December 2017 quarter underpinned higher throughput in the primary circuit while favourable market
conditions allowed the PC02 circuit to operate at full capacity. The PC02 circuit contributed 8% of total manganese ore
production in H1 FY18 (5% H1 FY17; 6% FY17). 
 
Saleable Manganese alloy production increased by 5%(or 4kt) to 82kt in H1 FY18. 
 
FY18 ore production guidance remains unchanged at 3.1Mwmt with the wet season expected to impact production across H2
FY18. 
 
Operating costs 
 
FOB manganese ore operating unit costs increased by 8% to US$1.55/dmtu in H1 FY18 as a result of a rise in planned
maintenance expenditure, a stronger Australian dollar and higher price-linked royalties. 
 
We have updated FY18 unit cost guidance to US$1.63/dmtu to reflect revised exchange rate and price assumptions. Exchange
rate and price assumptions for FY18 unit cost guidance are in footnote 20. 
 
Financial performance 
 
Underlying EBIT increased by 44% (or US$92M) in H1 FY18 to US$299M. A significant improvement in average realised ore and
alloys prices (+US$106M) and an increase in sales volumes (+US$20M) were only partially offset by a rise in planned
maintenance expenditure (-US$8M), the impact of a stronger Australian dollar and higher price-linked royalties (-US$7M). 
 
Our average realised price for external ore sales in H1 FY18 reflected the high grade 44% manganese lump ore index (CIF
China) on a volume weighted M-1 basis(23), despite the higher contribution of 40% grade PC02 product to the sales mix. 
 
Capital expenditure 
 
Sustaining capital expenditure increased to US$21M in H1 FY18 as we invested in additional tailings storage capacity at
GEMCO.

South Africa Manganese (ORE 44.4% SHARE, ALLOY 60% SHARE) 
 
Volumes 
 
South Africa Manganese ore production increased by 21% (or 195kwmt) to 1.1Mwmt in H1 FY18 as the continuation of higher
cost trucking and the sale of lower quality fines products enabled us to take advantage of favourable market conditions.
FY18 ore production guidance has been increased by 8% to 2,040kwmt, but remains subject to market demand. 
 
Manganese alloy saleable production decreased by 3% (or 1kt) to 36kt in H1 FY18 as Metalloys continued to operate one of
its four furnaces. 
 
Operating costs 
 
FOB manganese ore operating unit costs increased by 18% to US$2.31/dmtu in H1 FY18 as a result of a stronger South African
rand and higher price-linked royalties. The drawdown of low cost Wessels concentrate and other fines material stockpiles
offset the cost of opportunistically trucking ore to port. 
 
We have updated FY18 unit cost guidance to US$2.41/dmtu to reflect revised exchange rate and price assumptions, and a
continuation of higher cost trucking activity. Exchange rate and price assumptions for FY18 unit cost guidance are in
footnote 20. 
 
Financial performance 
 
Underlying EBIT increased by 87% (or US$40M) in H1 FY18 to US$86M as a significant improvement in ore and alloy prices
(+US$49M) was only partially offset by a stronger South African rand (-US$5M), higher price-linked royalties (-US$4M) and
an increase in trucking costs (-US$6M). 
 
Our average realised price for external ore sales in H1 FY18 reflected the medium grade 37% manganese lump ore index(24) on
a volume weighted M-1 basis. Wessels concentrate and other fines products receive a substantial discount when referenced to
index prices. Favourable negotiated price outcomes for our primary products and a temporary increase in the proportion of
sales priced in the month of shipping (i.e. M, as opposed to M-1) offset the impact of these discounts.

South Africa Manganese (ORE 44.4% SHARE, ALLOY 60% SHARE)
Volumes
South Africa Manganese ore production increased by 21% (or 195kwmt) to 1.1Mwmt
in H1 FY18 as the continuation of higher cost trucking and the sale of lower
quality fines products enabled us to take advantage of favourable market
conditions. FY18 ore production guidance has been increased by 8% to
2,040kwmt, but remains subject to market demand.
Manganese alloy saleable production decreased by 3% (or 1kt) to 36kt in H1
FY18 as Metalloys continued to operate one of its four furnaces.
Operating costs
FOB manganese ore operating unit costs increased by 18% to US$2.31/dmtu in H1
FY18 as a result of a stronger South African rand and higher price-linked
royalties. The drawdown of low cost Wessels concentrate and other fines
material stockpiles offset the cost of opportunistically trucking ore to port.
We have updated FY18 unit cost guidance to US$2.41/dmtu to reflect revised
exchange rate and price assumptions, and a continuation of higher cost
trucking activity. Exchange rate and price assumptions for FY18 unit cost
guidance are in footnote 20.
Financial performance
Underlying EBIT increased by 87% (or US$40M) in H1 FY18 to US$86M as a
significant improvement in ore and alloy prices (+US$49M) was only partially
offset by a stronger South African rand (-US$5M), higher price-linked
royalties (-US$4M) and an increase in trucking costs (-US$6M).
Our average realised price for external ore sales in H1 FY18 reflected the
medium grade 37% manganese lump ore index((24)) on a volume weighted M-1
basis. Wessels concentrate and other fines products receive a substantial
discount when referenced to index prices. Favourable negotiated price outcomes
for our primary products and a temporary increase in the proportion of sales
priced in the month of shipping (i.e. M, as opposed to M-1) offset the impact
of these discounts.
Capital expenditure
Sustaining capital expenditure increased to US$8M in H1 FY18.

Cannington (100% SHARE)
Volumes
Cannington silver, lead and zinc payable production decreased by 41%, 33% and
52% respectively in H1 FY18 as lower ore grades and a reduction in mill
throughput impacted performance.
The stress regime within the orebody is evolving with depletion and we are
moving to more challenging areas within the mine plan. In order to deliver
greater predictability and stability in the underground mine as the level of
activity increases (80 stopes to be extracted in FY19, average of 50:
FY12-16), we are lowering the mining rate to 2.45 Mt per annum which is
expected to translate to mill throughput of 2.3Mt and 2.4Mt in FY18 and FY19,
respectively.
Operating costs
Operating unit costs increased by 30% to US$170/t in H1 FY18 as a result of
the reduction in throughput and an adverse movement in finished goods
inventory.
We have updated FY18 unit cost guidance to US$159/t to reflect revised
exchange rate and price assumptions. Exchange rate and price assumptions for
FY18 unit cost guidance are in footnote 20.
Financial performance
Underlying EBIT decreased by 56% (or US$93M) in H1 FY18 to US$72M as lower
sales volumes (-US$148M) were partially offset by higher average realised
prices (+US$32M) and lower treatment and refining charges (+US$27M). The
ramp-up of underground trucking activity successfully replaced shaft haulage
in the period for a modest US$2M increase in costs. Finalisation adjustments
and the provisional pricing of Cannington concentrates increased Underlying
EBIT by US$5.5M in H1 FY18 (US$4.1M FY17; US$0.5M H1 FY17). Outstanding
concentrate sales (containing 1.8Moz of silver, 21.1kt of lead and 3.9kt of
zinc) were revalued at 31 December 2017. The final price of these sales will
be determined in H2 FY18.
Capital expenditure
Sustaining capital expenditure increased to US$23M inH1 FY18. The underground
crusher is now expected to be commissioned in February 2018, ahead of

NOTES
(1)    Revenue includes revenue from third party products.
(2)    H1 FY18 basic earnings per share is calculated as Profit/(loss)
after tax divided by the weighted average number of shares for H1 FY18 (5,191
million). H1 FY18 basic Underlying earnings per share is calculated as
Underlying earnings divided by the weighted average number of shares for H1
FY18. H1 FY17 basic earnings per share is calculated as Profit/(loss) after
tax divided by the weighted average number of shares for H1 FY17 (5,319
million). H1 FY17 basic Underlying earnings per share is calculated as
Underlying earnings divided by the weighted average number of shares for H1
FY17.
(3)    H1 FY18 ordinary dividend per share is calculated as H1 FY18 interim
dividend announced (US$223M) divided by the number of shares on issue at 31
December 2017 (5,181 million).
(4)    H1 FY18 special dividend per share is calculated as H1 FY18 special
dividend announced (US$155M) divided by the number of shares on issue at 31
December 2017 (5,181 million).
(5)    Underlying EBIT is profit before net finance costs, tax and any
earnings adjustment items, including impairments. Underlying EBIT is reported
inclusive of South32's share of net finance costs and tax of equity accounted
investments. Underlying EBITDA is Underlying EBIT, before depreciation and
amortisation. Underlying earnings is Profit/(loss) after tax and earnings
adjustment items. Underlying earnings is the key measure that South32 uses to
assess the performance of the South32 Group, make decisions on the allocation
of resources and assess senior management's performance. In addition, the
performance of each of the South32 operations and operational management are
assessed based on Underlying EBIT. In order to calculate Underlying earnings,
Underlying EBIT and Underlying EBITDA, the following items are adjusted as
applicable each period, irrespective of materiality:
·          Exchange rate gains/losses on restatement of monetary
items;
·          Impairment losses/reversals;
·          Net gain/loss on disposal and consolidation of interests
in businesses;
·          Fair value gain/loss on non-trading derivative
instruments;
·          Major corporate restructures; and
·          The income tax impact of the above items.
In addition, items that do not reflect the underlying operations of South32,
and are individually significant to the financial statements, are excluded to
determine Underlying earnings. Significant items are detailed in the Financial
Information.
(6)    Comprises Underlying EBITDA excluding third party product EBITDA,
divided by revenue excluding third party product revenue.
(7)    Comprises Underlying EBIT excluding third party product EBIT,
divided by revenue excluding third party product revenue.
(8)    Return on invested capital (ROIC) is a key measure that South32 uses
to assess performance. ROIC is calculated as annualised Underlying EBIT less
the discount on rehabilitation provisions included in net finance cost, tax
effected by the Group's Underlying effective tax rate (ETR), divided by the
sum of fixed assets (excluding any rehabilitation asset and impairments) and
inventories. Manganese is included in the calculation on a proportional
consolidation basis.
(9)    To ensure that incident classification definitions are applied
uniformly across our workforce, we have adopted the United States Government
Occupational Safety and Health Assessment (OSHA) guidelines for the recording
and reporting of occupational injuries and illnesses.
(10)   Total Recordable Injury Frequency (TRIF): The sum of (fatalities +
lost-time cases + restricted work cases + medical treatment cases) x 1,000,000
÷ actual hours worked, for employees and contractors. Stated in units of per
million hours worked.
(11)   Sales price variance reflects the revenue impact of changes in
commodity prices, based on the current period's sales volume. Price-linked
costs variance reflects the change in royalties together with the change in
input costs driven by changes in commodity prices or market traded
consumables. Foreign exchange reflects the impact of exchange rate movements
on local currency denominated costs and sales. Volume variance reflects the
revenue impact of sales volume changes, based on the comparative period's
sales prices. Controllable costs variance represents the impact from changes
in the Group's controllable local currency cost base, including the variable
cost impact of production volume changes on expenditure, and period-on-period
movements in inventories. The controllable cost variance excludes earnings
adjustments including significant items.
(12)   Underlying net finance cost and Underlying tax expense are actual H1
FY18 results, not half-on-half variances.
(13)   South32's ownership share of operations are presented as follows:
Worsley Alumina (86%), South Africa Aluminium (100%), Mozal Aluminium (47.1%
share), Brazil Alumina (Alumina 36% share, Aluminium 40% share), South Africa
Energy Coal (92% share), Illawarra Metallurgical Coal (100%), Australia
Manganese (60% share), South Africa Manganese (60% share), Cerro Matoso (99.9%
share), and Cannington (100%).
(14)   Underlying effective tax rate (ETR) is Underlying income tax expense,
excluding royalty related tax, divided by Underlying profit before tax; both
the numerator and denominator exclude equity accounted investments.
(15)   The Mozambique operations are subject to a royalty on revenues
instead of income tax.
(16)   Total capital expenditure comprises Capital expenditure, the purchase
of intangibles and capitalised exploration expenditure. Capital expenditure
comprises Sustaining capital expenditure and Major projects capital
expenditure. Sustaining capital expenditure comprises Stay-in-business (SIB),
Minor discretionary and Deferred stripping (including underground development)
capital expenditure.
(17)   South32's interest in South Africa Energy Coal is accounted at 100%
until Broad-Based Black Economic Empowerment (B-BBEE) vendor loans are repaid.
(18)   Operating unit cost is Revenue less Underlying EBITDA, excluding
third party sales, divided by sales volumeer annum which is
expected to translate to mill throughput of 2.3Mt and 2.4Mt in FY18 and FY19, respectively. 
 
Operating costs 
 
Operating unit costs increased by 30% to US$170/t in H1 FY18 as a result of the reduction in throughput and an adverse
movement in finished goods inventory. 
 
We have updated FY18 unit cost guidance to US$159/t to reflect revised exchange rate and price assumptions. Exchange rate
and price assumptions for FY18 unit cost guidance are in footnote 20. 
 
Financial performance 
 
Underlying EBIT decreased by 56% (or US$93M) in H1 FY18 to US$72M as lower sales volumes (-US$148M) were partially offset
by higher average realised prices (+US$32M) and lower treatment and refining charges (+US$27M). The ramp-up of underground
trucking activity successfully replaced shaft haulage in the period for a modest US$2M increase in costs. Finalisation
adjustments and the provisional pricing of Cannington concentrates increased Underlying EBIT by US$5.5M in H1 FY18 (US$4.1M
FY17; US$0.5M H1 FY17). Outstanding concentrate sales (containing 1.8Moz of silver, 21.1kt of lead and 3.9kt of zinc) were
revalued at 31 December 2017. The final price of these sales will be determined in H2 FY18. 
 
Capital expenditure 
 
Sustaining capital expenditure increased to US$23M inH1 FY18. The underground crusher is now expected to be commissioned in
February 2018, ahead of schedule.

NOTES TO FINANCIAL STATEMENTS - BASIS OF PREPARATION 
 
The consolidated financial statements of South32 Limited (referred to as the Company) and its subsidiaries and joint
arrangements (collectively, the Group) for the half year ended 31 December 2017 were authorised for issue in accordance
with a resolution of the Directors on 15 February 2018. 
 
1.    Reporting entity 
 
South32 Limited is a for-profit company limited by shares incorporated in Australia with a primary listing on the
Australian Securities Exchange (ASX), a standard listing on the London Stock Exchange and a secondary listing on the
Johannesburg Stock Exchange. The nature of the operations and principal activities of the Group are described in note 3
Segment information. 
 
2.    Basis of preparation 
 
The half year consolidated financial statements are a general purpose condensed financial report which:

the Corporations Act 
 
·      Have 

- More to follow, for following part double click  ID:nRSO9698Ec       Are presented in US dollars, which is the functional currency of
the majority of the Group's operations, and all values are rounded to the
nearest million dollars (US$M or US$ million) unless otherwise stated, in
accordance with ASIC Corporations Instrument 2016/191
·      Present reclassified comparative information where required for
consistency with the current period's presentation
·      Have been prepared on the basis of accounting policies and
methods of computation consistent with those applied in the 30 June 2017
annual consolidated financial statements
In preparing these half year consolidated financial statements, management has
made judgements, estimates and assumptions that affect the application of
accounting policies and the reported amounts of assets and liabilities, income
and expense. Actual results may differ from these estimates. The significant
judgements made by management in applying the Group's accounting policies and
the key sources of estimation uncertainty were the same as those that applied
to the consolidated financial statements as at and for the year ended 30 June
2017.
For a full understanding of the financial performance and financial position
of the Group it is recommended that the half year consolidated financial
statements be read in conjunction with the annual consolidated financial
statements for the year ended 30 June 2017. Consideration should also be given
to any public announcements made by the Company in accordance with the
continuous disclosure obligations of the ASX Listing Rules.

3.    Segment information
(a)   Description of segments
The operating segments (also referred to as operations), are organised and
managed separately according to the nature of products produced.
The members of the Lead Team (the chief operating decision makers) and the
Board of Directors monitor the segment results regularly for the purpose of
making decisions about resource allocation and performance assessment. The
segment information for the manganese operations are presented on a
proportional consolidation basis, which is the measure used by the Group's
management to assess their performance.
The principal activities of each operating segment as the Group is currently
structured are summarised as follows:
 Operating segment             Principal activities
 Worsley Alumina               Integrated bauxite mine and alumina refinery in Western Australia, Australia
 South Africa Aluminium        Aluminium smelter in Richards Bay, South Africa
 Mozal Aluminium               Aluminium smelter in Mozambique
 Brazil Alumina                Alumina refinery in Brazil
 South Africa Energy Coal      Open-cut and underground energy coal mines and processing operations in South
                               Africa
 Illawarra Metallurgical Coal  Underground metallurgical coal mines in New South Wales, Australia
 Australia Manganese           Integrated producer of manganese ore in the Northern Territory and manganese
                               alloys in Tasmania, Australia
 South Africa Manganese        Integrated producer of manganese ore and alloy in South Africa
 Cerro Matoso                  Integrated laterite ferronickel mining and smelting complex in Colombia
 Cannington                    Silver, lead and zinc mine in Queensland, Australia
 
All operations are operated or jointly operated by the Group except Brazil
Alumina, which is operated by Alcoa.
(b)   Segment results
The Group separately discloses sales of group production from sales of third
party products because of the significant difference in profit margin earned
on these sales.
It is the Group's policy that inter-segment transactions are made on a
commercial basis.
Group and unallocated items/eliminations represent group centre functions and
consolidation adjustments. Group financing (including finance expense and
finance income) and income taxes are managed on a Group basis and are not
allocated to operating segments.
