Financial Results and Outlook 
Half Year ended 31 December 2018


14 February 2019                                          
                                                                        
"Record production at Australia Manganese, strong operating performance more broadly and higher commodity prices 
delivered a 17 per cent increase in Profit after tax for the half year, while Underlying earnings per share grew by 
20 per cent as we continued to benefit from our on-market share buy-back program.  

"Our strong start to the year means that our production guidance is unchanged for all of our operations with the exception 
of Illawarra Metallurgical Coal where we have upgraded guidance by 7 per cent.  We have also lowered our unit cost guidance 
as we have maintained operating discipline and benefited from a stronger US dollar. 

"We continued to reshape our portfolio by acquiring the high-grade Hermosa resource and a 50% interest in and operatorship 
of the Eagle Downs Metallurgical Coal project during the period.  We are also progressing our early stage exploration projects 
and remain on track to divest South Africa Energy Coal with binding bids expected by 30 June 2019. 

"We are well positioned for the second half of the year, with a net cash balance of US$678M and an improving outlook for production 
and costs. This strong position has allowed us to return US$511M to shareholders in respect of the period with today's declaration of
 a US$258M fully franked interim dividend and an US$86M fully franked special dividend.

"Having established a strong track record, we will continue to return any excess capital to shareholders in a timely and efficient 
manner by monitoring our financial position within the context of the prevailing macro-economic environment and our capital management 
framework. This will involve the continuation of our existing US$1B capital management program with the recommencement of our on-market 
share buy-back following release of our financial results."

Safety
We are working hard to create a workplace where we can guarantee that everyone goes home safe and well at the end of every
shift. In order to make this breakthrough we are creating an inclusive workplace where all work is well-designed and we
continuously improve and learn. Our Total Recordable Injury Frequency (TRIF)(9)(10) declined from 5.1 to 4.8 per million hours
worked in H1 FY19.

Performance summary
The Group's statutory profit after tax increased by 17% to US$635M in H1 FY19, Underlying earnings increased by 18%
(or US$98M) to US$642M and basic Underlying earnings per share increased by 20% to US12.6 cents per share as we benefitted
from our on-market share buy-back program. This significant increase in profitability was driven by strong production, higher
commodity prices and disciplined cost control.

Following our strong start to the year and a favourable movement in currency markets, we have lowered FY19 Operating unit cost
guidance for the majority of operations, while production guidance for Illawarra Metallurgical Coal has been increased by 7% to 6.5Mt.

We have also lowered Capital expenditure(11) guidance, including equity accounted investments (EAI), by 9% to US$762M to 
reflect the reclassification of US$20M of planned exploration expenditure at Hermosa to capitalised exploration, the appreciation
of the US dollar and a lower rate of spend in H1 FY19 (US$349M).

Specific highlights included:
 -  A 106% increase in production at Illawarra Metallurgical Coal as the Appin colliery continued to ramp-up towards historical
    rates;
 -  Record ore production at Australia Manganese as the primary circuit maintained high utilisation rates and the
    Premium Concentrate Ore (PC02) circuit operated at 120% of design capacity;
 -  The commencement of several improvement initiatives at Worsley Alumina that are expected to support a sustainable increase
    in production to nameplate capacity of 4.6Mt (100% basis) ahead of future de-bottlenecking activities;
 -  Mineração Rio do Norte S.A (MRN) partner approval to undertake a pre-feasibility study for a project that has the potential to
    extend the life of the bauxite mine by more than 20 years(12) at a relatively low capital cost;
 -  The acquisition of the remaining 83% interest in Arizona Mining(13) for US$1.4B (including transaction costs), which adds the
 -  Hermosa project's high grade zinc-lead-silver resource(14) and a prospective land package to our portfolio; and
 -  The commencement of a feasibility study at Eagle Downs Metallurgical Coal, following our acquisition of a 50% interest in the
    project and assumption of operating control for US$106M(15).

Subsequent to period end we also elected to maintain our option with Trilogy Metals Inc. (TSX:TMQ) for the third and final year,
which retains our right to earn a 50% interest in the Upper Kobuk Mineral projects in Alaska by committing approximately US$150M
to a 50:50 joint venture by 31 January 2020.

We finished the period with a net cash balance of US$678M having generated free cash flow from operations, including
distributions from our manganese EAI, of US$718M. Our strong financial position and disciplined approach to capital management
has allowed us to return US$511M to shareholders in respect of the period, including:

 -  A US$258M fully franked interim dividend, which we have resolved to pay in April in accordance with our dividend policy
    which seeks to return a minimum 40% of Underlying earnings in each six month period;
 -  An US$86M fully franked special dividend, which we have also resolved to pay in April; and
 -  The continuation of our on-market share buy-back program whereby we purchased 68M shares at an average price of A$3.39
    per share for a cash consideration of US$167M.

With payment of this special dividend we will have completed 87% of our US$1B capital management program with the remaining
US$127M scheduled to be returned to shareholders by 10 April 2019, depending on market liquidity and value. Having
established a strong track record, we will continue to return any excess capital to shareholders in a timely and efficient manner by
monitoring our financial position within the context of the prevailing macroeconomic environment and our capital management
framework.

Earnings
The Group's statutory profit after tax increased by US$92M (or 17%) to US$635M in H1 FY19. Consistent with our accounting
policies, various items are excluded from the Group's statutory profit to derive Underlying earnings including: losses on fair value
movements of non-trading derivative instruments and other investments (US$28M pre-tax); exchange rate gains associated with
the Group's non US dollar denominated net debt (US$21M pre-tax); the tax expense for all pre-tax earnings adjustments and
exchange rate variations on tax balances (US$11M), and profit associated with earnings adjustments included in our EAI
(US$11M). Further information on these earnings adjustments is included further on.

On this basis, the Group generated Underlying EBITDA of US$1.3B for an operating margin of 38% as stronger volumes, primarily
at Illawarra Metallurgical Coal, and higher average realised prices underpinned a US$300M increase in sales revenue, excluding
third party products. The Group's Operating unit costs also benefitted from weaker producer currencies, however total costs rose
with higher production and price-linked royalties, elevated raw material costs across our aluminium value chain and an increase in
maintenance costs at Worsley Alumina. Depreciation and amortisation also increased by a modest US$17M to US$380M, meaning
that Underlying EBIT increased by US$201M (or 28%) to US$925M. This higher level of profitability, a change in our geographic
earnings mix and permanent differences led to a US$103M (or 85%) increase in our Underlying income tax expense to US$224M.
As a result, Underlying earnings increased by US$98M (or 18%) to US$642M.

Net finance cost

The Group's Underlying net finance cost, excluding EAI, was US$59M in H1 FY19, which primarily reflects the unwinding of the
discount applied to our closure and rehabilitation provisions (US$52M), finance lease interest (US$25M) and interest on our net cash
balances (US$22M).

Tax expense
The Group's Underlying income tax expense, which excludes tax associated with EAI, was US$224M for an Underlying effective
tax rate(20) (ETR) of 37.3% in H1 FY19 (H1 FY18: 28.0%). The increase in ETR reflects the differing tax rates that our operations
are exposed to and the change in our geographic earnings mix, and the disproportionate effect of intragroup agreements and other
permanent differences when margins are compressed or losses are incurred in specific jurisdictions. The primary corporate tax
rates applicable to the Group for H1 FY19 include: Australia 30%, South Africa 28%, Colombia 37%(21), Mozambique 0%(21) and
Brazil 34%.

The Underlying income tax expense for our manganese EAI was US$172M, including royalty related taxation of US$42M at
GEMCO (Australia Manganese), for an Underlying ETR of 38.8% (H1 FY18: 36.2%).

Cash flow
The Group's free cash flow from operations, excluding EAI, was US$456M in H1 FY19. Working capital increased by US$93M as
we established inventories at Illawarra Metallurgical Coal ahead of two longwall moves in Q3 FY19 and the timing of shipments
impacted sales at Mozal Aluminium. Provisions and other liabilities also declined as we continued to invest in progressive
rehabilitation at South Africa Energy Coal. These impacts were partially offset by movements in receivables and payables, with no
change to our payment terms with customers or suppliers. Our debtor days remained broadly unchanged at 22.

Total capital expenditure(11), excluding EAI, increased by US$104M to US$306M in H1 FY19 as Major project activity ramped up at
the Klipspruit Life Extension (KPSX) project(22) and preliminary work was undertaken to progress the Hermosa project following the
acquisition of Arizona Mining in August 2018. Total capital expenditure included:

 -  Sustaining capital expenditure, comprising Stay-in-business, Minor discretionary and Deferred stripping
    (including underground development) of US$206M (H1 FY18: US$195M); and
 -  Major project capital expenditure of US$90M (H1 FY18: US$4M) relating to the KPSX (US$55M), Hermosa (US$33M) and
    Eagle Downs Metallurgical Coal (US$2M) projects.

The purchase of intangibles and the capitalisation of exploration expenditure accounted for a further US$10M (H1 FY18: US$3M).

Total capital expenditure associated with EAI increased by US$24M to US$53M during H1 FY19 as we invested in additional
tailings storage capacity at Australia Manganese.

Total capital expenditure, including EAI, in H1 FY19 was US$359M (H1 FY18: US$231M).

We also received (net) distributions totalling US$262M from our manganese EAI in H1 FY19, comprising dividends and capital
returns totalling US$286M and a modest drawdown in shareholder loans (-US$24M).

Balance sheet, dividends and capital management

While the Group generated free cash flow from operations, including net distributions from EAI, of US$718M
(H1 FY18: US$290M), our net cash balance decreased by US$1.4B to US$678M at 31 December 2018 (30 June 2018: US$2.0B)
as we funded the Arizona Mining and Eagle Downs Metallurgical Coal transactions out of our cash reserves for a combined
investment of US$1.5B. We also paid our final shareholder dividend in respect of FY18 of US$316M and directed US$167M
towards our on-market share buy-back program as we purchased 68M shares at an average price of A$3.39 per share.

Demonstrating the disciplined and flexible approach we are taking to our capital management program, our Board resolved to pay
a fully franked interim dividend of US$258M, representing 40% of Underlying earnings in H1 FY19, and a fully franked special
dividend of US$86M. With payment of this special dividend we will have completed 87% of our US$1B capital management
program with the remaining US$127M scheduled to be returned to shareholders by 10 April 2019, depending on market liquidity
and value.

Our capital management framework remains unchanged and we continue to believe that a combination of high operating leverage
and undue financial leverage delivers a sub-optimal outcome for shareholders. With the declaration of our interim and special
dividends, this approach will allow us to return US$2.4B to shareholders in respect of the last three year period, equivalent to 20%
of our market capitalisation(23). Having established this strong track record, we will continue to return any excess capital to
shareholders in a timely and efficient manner by monitoring our financial position within the context of the prevailing
macroeconomic environment and our capital management framework.

Consistent with our commitment to maintain an investment grade credit rating, Standard and Poor's and Moody's reaffirmed their
respective BBB+ and Baa1 credit ratings for the Group.

Costs and capital expenditure

Operating unit cost performance

Broad appreciation of the US dollar and robust operating performance ensured that Operating unit costs were well controlled at the
majority of our upstream operations in H1 FY19, however underlying inflationary pressure from raw materials continued to impact
our aluminium value chain with the greatest pressure being felt at our smelters.

      The H1 FY19 results reflect the Group's adoption of AASB 15 Revenue from Contracts with Customers, with revenue recognised net of treatment and refining
      charges (previously recognised on a gross basis with treatment and refining charges included as a separate expense). These changes result in lower realised
      prices and Operating unit costs, with no net impact to earnings. FY19 prior guidance has been adjusted from US$147/t to US$131/t to reflect these changes.
      Prior periods have not been restated to reflect these changes.

Operating unit cost guidance

Updated FY19 Operating unit cost guidance primarily reflects revised currency and price assumptions as production guidance has
been maintained for the majority of our operations. Illawarra Metallurgical Coal is the exception as an improvement in longwall
performance has underpinned a 7% increase to prior production guidance. That being said, the relative skew in production to either
H1 FY19 or H2 FY19 for a number of operations will have a meaningful impact on half-on-half unit cost performance. Separately,
Operating unit costs at our refineries will benefit from lower raw material costs in H2 FY19 as higher priced material that was held in
inventory was consumed in H1 FY19.

      revenue recognised net of treatment and refining charges (previously recognised on a gross basis with treatment and refining charges included as a separate
      expense). These changes result in lower realised prices and Operating unit costs, with no net impact to earnings.

Other expenditure guidance

FY19 guidance for Group and unallocated costs, excluding greenfield exploration, is unchanged at US$80M (H1 FY19: US$40M).
While guidance for greenfield exploration expenditure to progress our early stage projects also remains unchanged at US$41M
(H1 FY19: US$8M), we do expect to capitalise US$20M (H1 FY19: US$7M) of exploration expenditure to increase our knowledge
of the Hermosa resource(14).

Depreciation and amortisation, and tax expense

Depreciation and amortisation guidance for FY19 is unchanged at approximately US$750M (H1 FY19: US$380M), excluding EAI,
and US$85M (H1 FY19: US$44M) for our EAI. From a taxation perspective, our geographic earnings mix will have a significant
bearing on our ETR given differing country tax rates, while the impact of intragroup agreements and other permanent differences
will continue to be magnified when margins are compressed or losses are incurred in specific jurisdictions. Whilst it is therefore
difficult to predict our ETR (excluding EAI), we do expect it to decline in H2 FY19, particularly if the alumina to aluminium price ratio
falls.

Capital expenditure guidance

We have lowered FY19 guidance for Sustaining capital expenditure, including EAI, by US$30M to US$545M. This adjustment primarily
reflects appreciation of the US dollar, the lower rate of underground development at Illawarra Metallurgical Coal in H1 FY19 and
additional expenditure incurred to recover from and mitigate the impact of the Klipspruit dragline incident at South Africa Energy
Coal. This incident has been confirmed as an insurable event and we are working through the claim to assess the quantum and
timing of any recovery.

Major project capital expenditure guidance for FY19 has been lowered by US$48M to US$217M. This reduction primarily reflects
the reclassification of US$20M of expenditure to capitalised exploration at Hermosa, the timing of activity at South Africa Energy Coal's KPSX
project and appreciation of the US dollar. The modest reduction in underlying activity at Hermosa from Arizona Mining's preliminary
estimate is not expected to have a bearing on the development schedule as the deferral of activity to progress the twin exploration
declines does not impact the critical path. Capital expenditure required to progress the Eagle Downs Metallurgical Coal project (US$7M) is
also included within guidance for the first time as the transaction was concluded in the period. Major project capital expenditure
guidance does not account for the potential progression of the Dendrobium next domain project at Illawarra Metallurgical into final
feasibility in H2 FY19.

Worsley Alumina (86% share)

Volumes

Worsley Alumina saleable production increased by 2% (or 41kt)
in H1 FY19 to 1,906kt as the refinery benefitted from improved
calciner availability in Q2 FY19 and three shipments of
stockpiled hydrate were sold opportunistically at alumina
equivalent rates. FY19 production guidance remains unchanged
at 3,965kt with calciner maintenance scheduled for Q3 FY19.

Operating costs

Operating unit costs increased by 4% in H1 FY19 to US$233/t
as additional calciner maintenance was undertaken and the cost
of caustic soda increased as higher priced inventory was
consumed (H1 FY19: US$535/t, H1 FY18: US$516/t), which
more than offset the impact of a weaker Australian dollar.

We have lowered FY19 Operating unit cost guidance by US$3/t
to US$227/t with revised exchange rate and raw material price
assumptions partially offset by additional maintenance activity
that is designed to improve calciner performance and
sustainably achieve nameplate capacity. Conversely, caustic
soda costs are expected to decline in H2 FY19 as we benefit
from the recent reduction in market prices and a fall in
consumption rates as the contribution of West Marradong feed
rises. Exchange rate and price assumptions for FY19 Operating
unit cost guidance are detailed in footnote 29.

Financial performance

Underlying EBIT increased by 110% (or US$180M) in H1 FY19
to US$344M. A 29% rise in the average realised price of
alumina (+US$188M) and a weaker Australian dollar
(+US$23M) were partially offset by additional maintenance
costs (-US$10M) and an increase in the price of caustic soda 
(-US$4M).

The average realised price for alumina sales in H1 FY19
reflected a discount of 9% to the Platts Alumina Index (PAX) on
a volume weighted M-1 basis. This discount reflects the
structure of specific legacy supply contracts with our Mozal
Aluminium smelter that are linked to the LME aluminium price
and the elevated alumina to aluminium price ratio in the spot
market. All alumina sales to other customers were at market
based prices.

Capital expenditure

Sustaining capital expenditure increased by US$3M in H1 FY19
to US$25M and is expected to increase to US$60M in FY19 as
we commence several improvement initiatives to support a
sustainable increase in production to nameplate capacity of
4.6Mt (100% basis) and continue to invest in additional bauxite
residue disposal capacity.

Brazil Alumina (Alumina 36% share, Aluminium 40% share)

Volumes

Brazil Alumina saleable production decreased by 6% (or 40kt) in
H1 FY19 to 636kt as unplanned maintenance and power
outages impacted performance. FY19 production is expected to
approach guidance of 1,355kt with the addition of package
boilers designed to support the ramp-up of the De-bottlenecking
Phase One project.

Operating costs

Operating unit costs increased by 24% in H1 FY19 to US$291/t
as additional maintenance costs were incurred, higher priced
caustic soda inventory was consumed and the cost of bauxite
supplied by MRN increased as the price reset to reflect the
movement in alumina and aluminium prices on a trailing basis.

While specific Operating unit cost guidance is not provided as
we are not the operator of the refinery, we do expect some relief
from recent inflationary pressure in H2 FY19 given an expected
reduction in bauxite and caustic soda costs.

Financial performance

Alumina Underlying EBIT increased by 76% (or US$45M) in
H1 FY19 to US$104M as a 36% increase in the average
realised price of alumina (+US$84M) was partially offset by
lower sales volumes (-US$11M), additional maintenance 
(-US$4M) and higher bauxite (-US$12M) and caustic soda (-US$8M) costs.

Aluminium Underlying EBIT increased by US$5M in H1 FY19 to
a loss of US$7M as an indirect legacy tax obligation was settled
and our commitment to purchase electricity from Eletronorte
was fulfilled during the prior period following termination of the
contract in December 2015.

Capital expenditure

Sustaining capital expenditure increased by US$6M in H1 FY19 to
US$16M and is expected to increase to US$32M in FY19 as we
invest in additional bauxite residue disposal capacity.

The partners of MRN also agreed to undertake a pre-feasibility
study for a project that has the potential to extend the life of
the mine by more than 20 years at a relatively low capital
cost. MRN has a substantial 503Mt(12) high grade bauxite
resource.

Hillside Aluminium (100%)

Volumes

Hillside Aluminium saleable production increased by 1% (or 2kt)
in H1 FY19 to 360kt as the smelter continued to test its
maximum technical capacity, despite an increase in the
frequency of load-shedding events. FY19 production guidance remains
unchanged at 720kt, but remains subject to load-shedding.

Operating costs

Operating unit costs increased by 29% in H1 FY19 to
US$2,161/t as a significant rise in raw material costs created
inflationary pressure across the aluminium industry. Alumina,
coke, pitch and aluminium price-linked electricity accounted for
71% of the smelter's cost base in H1 FY19 (H1 FY18: 69%).
108 pots were also relined at a cost of US$233k per pot (H1
FY18: 44 pots at US$196k per pot), while 177 pots are
scheduled to be relined across FY19 as we reach a peak in the
relining cycle.

While Operating unit cost guidance is not provided, the cost
profile of Hillside Aluminium will continue to be heavily
influenced by the price of power and raw material inputs, given
its highly variable cost base. The smelter sources alumina from
our Worsley Alumina refinery with prices linked to the Platts
alumina index on an M-1 basis, while its power is sourced from
Eskom under long-term contracts. The price of electricity
supplied to potlines 1 and 2 is linked to the LME aluminium price
and the South African rand/US dollar exchange rate. The price
of electricity supplied to potline 3 is South African rand based.

Financial performance

Underlying EBIT decreased by 133% (or US$159M) in H1 FY19
to a loss of US$39M as stronger sales volumes (+US$35M) and
lower aluminium price-linked power costs (+US$5M) were more
than offset by higher raw material input costs (-US$136M), an
increase in pot relining costs (-US$16M) and an unfavourable
movement in inventory (-US$50M).

Capital expenditure

Sustaining capital expenditure remained largely unchanged in
H1 FY19 at US$12M and is expected to increase to US$18M in
FY19.

Mozal Aluminium (47.1% share)

Volumes

Mozal Aluminium saleable production decreased by 1% (or 2kt)
in H1 FY19 to 135kt as the smelter's operating performance
was impacted by an increase in the frequency of load-shedding
events. FY19 production guidance remains unchanged at 269kt,
subject to load-shedding, whilst the shortfall in sales volumes in
H1 FY19 simply reflects timing differences.

Operating costs

Operating unit costs increased by 14% in H1 FY19 to
US$1,938/t as a significant rise in raw material input costs
created inflationary pressure across the aluminium industry.
Alumina, coke and pitch accounted for 53% of the smelter's cost
base in H1 FY19 (H1 FY18: 48%). 40(33) pots were also relined 
across H1 FY19 at a cost of US$219k per pot (H1 FY18: 34(33) pots 
at US$191k per pot), with 103(33) pots scheduled to be relined in 
FY19 as we reach a peak in the relining cycle.

While Operating unit cost guidance is not provided, the cost
profile of Mozal Aluminium will continue to be heavily influenced
by the price of power and raw material inputs, given its highly
variable cost base. The smelter sources 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 an M-1
basis, with caps and floors embedded within specific contracts.
Its electricity requirements are largely met by hydroelectric
power that is generated by Hidroeléctrica de Cahora Bassa(HCB).

HCB delivers power into Eskom's South African grid and Mozal
Aluminium sources electricity via the Mozambique Transmission
Company (Motraco) under a long-term contract. The price of
electricity is South African rand based with the rate of escalation
linked to a South Africa domestic producer price index.

Financial performance

Underlying EBIT decreased by 78% (or US$47M) in H1 FY19 to
US$13M as lower sales volumes (-US$40M) and higher raw
material costs (-US$29M) were partially offset by a build in
finished goods (+US$28M).

Capital expenditure

Sustaining capital expenditure was unchanged in
H1 FY19 at US$8M as the US$18M AP3XLE energy efficiency
project commenced the roll out of its pot relining program ahead
of schedule. The project is expected to deliver a circa 5%
(or 10kt pa) increase in annual production with no associated
increase in power consumption. First incremental production is
anticipated in FY20, with the full benefit to be realised by FY24.
Sustaining capital expenditure of US$20M is anticipated in
FY19.

                 (a)   H1 FY18 reflects balance as at 30 June 2018.

South Africa Energy Coal (92% share(25))

Volumes

South Africa Energy Coal saleable production decreased by 9%
(or 1,252kt) in H1 FY19 to 12.2Mt as export production was
impacted by the dragline incident at Klipspruit in August 2018.
Conversely, domestic production benefitted from the
commencement of a contract to sell lower quality stockpiled
product in Q1 FY19.

FY19 production guidance remains unchanged at 29Mt
(17.5Mt domestic, 11.5Mt export), with the recommissioning of
the Klipspruit dragline in January 2019 underpinning an
increase in export volumes in H2 FY19. Domestic volumes are
also expected to benefit from a further increase in the sale of
lower quality stockpiled product and the implementation of a
new shift pattern at Khutala.

Operating costs

Operating unit costs increased by 6% in H1 FY19 to US$38/t as
the impact of the extended dragline outage more than offset a
weaker South African rand.

We have lowered FY19 Operating unit cost guidance by US$3/t
to US$38/t to reflect the dragline's return to service ahead of
schedule and revised exchange rate and price assumptions.
Exchange rate and price assumptions for FY19 Operating unit
cost guidance are detailed in footnote 29.

Financial performance

Underlying EBIT decreased by 88% (or US$101M) in H1 FY19
to US$14M as lower sales volumes (-US$134M), a drawdown in
inventory associated with the extended dragline outage
(-US$10M), higher depreciation (-US$10M) and general inflation
(-US$24M) were only partially offset by higher average realised
prices (+US$39M), a volume related reduction in rail costs
(+US$22M) and a weaker South African rand (+US$18M).

Capital expenditure

Sustaining capital expenditure decreased by US$20M in
H1 FY19 to US$48M. FY19 guidance has been increased by
US$34M to US$100M as additional expenditure has been
incurred to recover from and mitigate the impact of the
Klipspruit dragline incident. This incident has been 
confirmed as an insurable event and we are working through
the claim to assess the quantum and timing of any recovery.

We also invested US$55M in Major project capital expenditure
in H1 FY19 to progress the 4.3B(22) South African rand KPSX
project, which was approved by the Board in November 2017.
The 8Mt per annum brownfield project extends the life of the
colliery by more than 20 years(34). The project is approximately
33% complete and remains on schedule and budget, with first
production expected in H2 FY19. Major project expenditure of
US$140M is expected in FY19.

Illawarra Metallurgical Coal (100% share)

Volumes

Illawarra Metallurgical Coal saleable production increased by
106% (or 1,980kt) in H1 FY19 to 3.8Mt as the Dendrobium 
and Appin longwalls performed strongly. Metallurgical coal
stockpiles were also established during H1 FY19 in advance of
the two longwall moves scheduled in Q3 FY19. FY19 production
guidance has been increased by 7% to 6.5Mt to reflect the
strong start to the year.

We also reached agreement with employees covered by the
Dendrobium Coal Prep Plant Enterprise Agreement in January
2019, having previously reached agreement with the
Dendrobium mine's trades and operators, and Appin deputies
during H1 FY19. We continue to renegotiate the remaining
labour agreements at Illawarra Metallurgical Coal.

Operating costs

Operating unit costs decreased by 42% in H1 FY19 to US$87/t
as the operation benefitted from a substantial increase in sales
volumes.

We have lowered FY19 Operating unit cost guidance by US$8/t
to US$97/t to reflect the increase in production guidance and
revised exchange rate and price assumptions. Notwithstanding
this reduction in FY19 guidance, costs are expected to increase
in H2 FY19 as a result of the planned longwall moves.
Exchange rate and price assumptions for FY19 Operating unit
cost guidance are detailed in footnote 29.

Financial performance

Underlying EBIT increased by US$279M in H1 FY19 to
US$195M as stronger sales volumes (+US$327M) and a
weaker Australian dollar (+US$20M) were partially offset by an
increase in price-linked royalties (-US$22M) and depreciation 
(-US$18M). The volume related impact on costs (-US$41M) was
tempered by the high fixed cost base of the operation.

Capital expenditure

Sustaining capital expenditure increased by US$16M in H1
FY19 to US$56M as underground development progressively
recovered at Appin, albeit at a slower rate than planned.
A substantial uplift in development rates is required to sustain
the operation of two longwalls in parallel from H2 FY20.

Sustaining capital expenditure guidance for FY19 has been
reduced by US$42M to US$128M, including underground
development of US$75M (US$97M previously).

Australia Manganese (60% share)

Volumes

Australia Manganese achieved record ore performance in
H1 FY19, increasing saleable ore production by 6% (or
110kwmt) to 1,811kwmt. The primary circuit continued to
achieve high utilisation rates, while the PC02 circuit operated at
approximately 120% of its design capacity, contributing 9% of
total production. FY19 production guidance remains unchanged
at 3,350kwmt, with the wet season expected to impact
production across H2 FY19.

Saleable manganese alloy production decreased by 7% (or 6kt)
in H1 FY19 to 76kt as a result of an unplanned outage at one of
the four furnaces during Q2 FY19. While the furnace has
subsequently returned to service, additional maintenance is
planned for H2 FY19.

Operating costs

FOB manganese ore Operating unit costs decreased by 3% in
H1 FY19 to US$1.51/dmtu as record performance mitigated a
further increase in strip ratio (H1 FY19: 4.1, H1 FY18: 3.6).

We have lowered FY19 Operating unit cost guidance by
US$0.06/dmtu to US$1.57/dmtu to reflect the continued
improvement in equipment productivity and revised exchange
rate and price assumptions. Exchange rate and price
assumptions for FY19 Operating unit cost guidance are detailed
in footnote 29.

Financial performance

Underlying EBIT increased by 18% (or US$53M) in H1 FY19 to
US$352M as higher realised ore prices (+US$45M), an
increase in ore sales volumes (+US$28M) and a weaker
Australian dollar (+US$9M) were only partially offset by lower
realised alloy prices (-US$9M) and a rise in raw material and
freight costs (-US$10M).

Our average realised price for external ore sales in
H1 FY19 reflected the high grade 44% manganese lump ore
index (CIF China) on a FOB adjusted, volume weighted
M-1 basis(37), despite the higher contribution of 40% grade
PC02 product to the sales mix.

Capital expenditure

Sustaining capital expenditure increased by US$15M in H1
FY19 to US$36M as we invested in additional tailings capacity.
Sustaining capital expenditure of US$65M is anticipated in
FY19.

(a)   H1 FY18 reflects balance as at 30 June 2018.

South Africa Manganese (Ore 44.4% share, Alloy 60% share)

Volumes

South Africa Manganese saleable ore production decreased by
5% (or 54kwmt) in H1 FY19 to 1,075kwmt as an increase in
higher quality premium material was more than offset by a
decline in fine grained secondary products. While FY19
production guidance remains unchanged at 2,050kwmt, we will
continue to monitor market demand and optimise the use of
higher cost trucking.

Saleable manganese alloy production decreased by 8% (or 3kt)
in H1 FY19 to 33kt as a planned furnace shutdown was
completed.

Operating costs

FOB manganese ore Operating unit costs increased by 14% in
H1 FY19 to US$2.63/dmtu as we continued to utilise higher cost
trucking as an additional route to market and the contribution of
premium ore from our underground Wessels mine increased.

FY19 Operating unit cost guidance is unchanged at
US$2.56/dmtu. Exchange rate and price assumptions for
FY19 Operating unit cost guidance are detailed in footnote 29.

Financial performance

Underlying EBIT increased by 16% (or US$14M) in H1 FY19 to
US$100M as higher realised ore prices (+US$43M) and a
weaker South African rand (+US$6M) were partially offset by
lower realised alloy prices (-US$8M), a reduction in other
income (-US$11M) and general inflation (-US$5M).

Our lower quality fine grained material, which accounted for
10% of sales across H1 FY19 (15% H1 FY18; 13% FY18),
receives a product discount when referenced to index prices.
Notwithstanding the contribution of this secondary material to
our sales mix, our average realised price for external sales of
South African ore achieved the medium grade 37%
manganese lump ore index price (FOB Port Elizabeth, South
Africa) on a volume weighted M-1 basis(42).

Capital expenditure

Sustaining capital expenditure increased by US$9M in H1 FY19
to US$17M and is expected to increase to US$30M in FY19.

Cerro Matoso (99.9% share)

Volumes

Cerro Matoso payable nickel production decreased by 3%
(or 0.7kt) in H1 FY19 to 21.1kt following a planned increase in
the contribution of lower grade stockpiled ore feed. FY19
production guidance remains unchanged at 40.5kt.

Operating costs

Operating unit costs increased by 19% in H1 FY19 to
US$4.05/lb, primarily as a result of higher price-linked royalties
and energy costs.

We have lowered FY19 Operating unit cost guidance by
US$0.09/lb to US$4.12/lb to primarily reflect the benefit of
revised exchange rate and price assumptions, which are
partially offset by costs arising from the Constitutional Court of
Colombia ruling(30). Exchange rate and price assumptions for
FY19 Operating unit cost guidance are detailed in footnote 29.

Financial performance

Underlying EBIT decreased by US$31M in H1 FY19 to US$10M
as higher price-linked royalties (-US$8M), energy costs
(-US$8M), general inflation (-US$4M) and throughput
(-US$3M) were partially offset by a weaker Colombian peso
(+US$3M).

Finalisation adjustments and the provisional pricing of Nickel
sales decreased Underlying EBIT by US$16M in H1 FY19
(+US$19M FY18; +US$5M H1 FY18). Outstanding Nickel sales
(3.3kt of nickel) were revalued at 31 December 2018. The final
price of these sales will be determined in H2 FY19.

Capital expenditure

Sustaining capital expenditure increased marginally to US$13M
in H1 FY19 and is expected to increase to US$37M in FY19 as we
prepare for the planned furnace refurbishment in FY20.

(a)   H1 FY18 reflects balance as at 30 June 2018.

Cannington (100% share)

Volumes

Cannington payable zinc equivalent(26) production increased
by 11% (or 9.8kt) in H1 FY19 to 95.2kt as silver and zinc
grades improved and mill throughput tracked to plan. FY19
zinc equivalent production guidance is unchanged at 188.1kt
(silver 11,750koz, lead 98.0kt and zinc 51.0kt), but remains
subject to review pending our assessment of the impact to
logistics infrastructure resulting from the floods in North
Queensland.

Operating costs

Operating unit costs decreased by 29% to US$120/t in H1 FY19
as the adoption of AASB 15 Revenue from Contracts with
Customers(19), which affects the accounting classification of
treatment and refining charges, reduced costs by US$21/t.
A temporary build in finished goods inventory and stronger
throughput rates provided a further benefit.

We have lowered FY19 Operating unit cost guidance by US$2/t
to US$129/t(a) to reflect the benefit of revised exchange rate and
price assumptions, which are partially offset by an increase in
mining and rehabilitation activity. Exchange rate and price
assumptions for FY19 Operating unit cost guidance are detailed
in footnote 29.

Financial performance

Underlying EBIT decreased by 35% (or US$25M) in H1 FY19 to
US$47M as lower average realised prices (-US$61M)(b) were
partially offset by inventory movements (+US$13M), a weaker
Australian dollar (+US$10M) and higher sales volumes
(+US$8M).

Finalisation adjustments and the provisional pricing of
Cannington concentrates decreased Underlying EBIT by
US$9.8M in H1 FY19 (US$0.1M FY18; US$5.5M H1 FY18).
Outstanding concentrate sales (containing 2Moz of silver,
25.3kt of lead and 6.2kt of zinc) were revalued at 31
December 2018. The final price of these sales will be
determined in H2 FY19.

Capital expenditure

Sustaining capital expenditure increased by US$5M in H1 FY19
to US$28M and is expected to increase to US$55M in FY19.

(a)   FY19 Prior guidance has been adjusted from US$147/t to US$131/t to
      reflect the Group's adoption of AASB 15 Revenue from Contracts with
      Customers, with revenue recognised net of treatment and refining
      charges (previously recognised on a gross basis with treatment and
      refining charges included as a separate expense). These changes result
      in lower realised prices and Operating unit costs, with no net impact to
      earnings. Prior periods have not been restated to reflect the changes.
(b)   Excludes the impact of the change in accounting treatment for treatment
      and refining charges on revenue (-US$20M). This impact is equally
      offset by a reduction in costs (+US$20M).
(c)   H1 FY18 reflects balance as at 30 June 2018.

Notes

(1)   Revenue includes revenue from third party products and services.

(2)   H1 FY19 basic earnings per share is calculated as Profit/(loss) after tax divided by the weighted average number of shares for H1 FY19 (5,079 million).
      H1 FY19 basic Underlying earnings per share is calculated as Underlying earnings divided by the weighted average number of shares for H1 FY19.
      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.

(3)   H1 FY19 ordinary dividends per share is calculated as H1 FY19 ordinary dividend announced (US$258M) divided by the number of shares on issue at
      31 December 2018 (5,051 million).

(4)   H1 FY19 special dividends per share is calculated as H1 FY19 special dividend announced (US$86M) divided by the number of shares on issue at
      31 December 2018 (5,051 million). Paragraph 16.26(i) of the Johannesburg Stock Exchange (JSE) listing rules states that the requisite exchange control authority
      from the Financial Surveillance Department of the South African Reserve Bank (SARB) is required to be provided to the JSE before the JSE can approve payment
      of special dividends to South African shareholders.

(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 (gains)/losses on disposal and consolidation of interests in businesses;
       -   Fair value (gains)/losses on non-trading derivative instruments and other investments;
       -   Major corporate restructures; and
       -   Earnings adjustments included in profit/(loss) of equity accounted investments.
    
      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 unproductive capital spent on Major projects) 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)  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.

(12)  The information in this report that relates to Mineral Resource estimates for MRN was declared as part of South32's Annual Resource and Reserve declaration in
      the Annual Report 2018 (www.south32.net) issued on 7 September 2018 and prepared by M A H Monteiro 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 announcement. All material
      assumptions and technical parameters underpinning the estimates in the relevant market announcement continue to apply and have not materially changed.
      South32 confirms that the form and context in which the Competent Person's findings are presented have not been materially modified from the original market
      announcement.

(13)  Refer to exchange release on 13 August 2018 "South32 completes acquisition of Arizona Mining".

(14)  The information that relates to estimates of Mineral Resources for the Hermosa Project are qualifying foreign estimates under ASX Listing Rules and reference
      should be had to the clarifying statement on Mineral Resources in the market announcement 'South32 to acquire Arizona Mining in agreed all cash offer' dated 18
      June 2018, in accordance with ASX Listing Rule 5.12. South32 is not in possession of any new information or data relating to the foreign estimate that materially
      impacts on the reliability of the estimates. South32 confirms that the information contained in the clarifying statement in the 18 June 2018 market announcement
      continues to apply and has not materially changed. The estimates of Mineral Resources are not reported in accordance with the JORC Code. Competent persons
      have not done sufficient work to classify the foreign estimates as Mineral Resources in accordance with JORC Code. It is uncertain that following evaluation and
      further exploration that the foreign estimates will be able to be reported as Mineral Resources or Ore Reserves in accordance with the JORC Code.

(15)  Refer to media release on 14 September 2018 "South32 completes acquisition of 50% interest in Eagle Downs and assumes operatorship".

(16)  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.

(17)  Underlying net finance cost and Underlying income tax expense are actual H1 FY19 results, not half-on-half variances.

(18)  South32's ownership share of operations are presented as follows: Worsley Alumina (86% share), Hillside Aluminium (100%), Mozal Aluminium (47.1% share),
      Brazil Alumina (Alumina 36% share, Aluminium 40% share), South Africa Energy Coal (100% share until Broad-Based Black Economic Empowerment (B-BBEE)
      vendor loans are repaid), Illawarra Metallurgical Coal (100%), Australia Manganese (60% share), South Africa Manganese (60% share), Cerro Matoso (99.9%
      share), and Cannington (100%).

(19)  The H1 FY19 results reflect the Group's adoption of AASB 15 Revenue from Contracts with Customers, with revenue recognised net of treatment and refining
      charges (previously recognised on a gross basis with treatment and refining charges included as a separate expense). These changes result in lower realised
      prices and Operating unit costs, with no net impact to earnings. Prior periods have not been restated to reflect these changes.

(20)  Underlying 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.

(21)  The Colombian corporate tax rate was 40% during CY17, 37% during CY18 and is 33% in CY19. The corporate tax rate will decrease on an annual basis by a
      percent each year, stabilising at 30% from 1 January 2022. The Mozambique operations are subject to a royalty on revenues instead of income tax.

(22)  Refer to the market announcement "South32 approves Klipspruit Life Extension Project" dated 27 November 2017.

(23)  Market capitalisation as at 31 December 2018. Calculated as the number of shares on issue (5,051 million), the South32 closing share price A$3.35, and an
      AUD:USD exchange rate of 0.71.

(24)  Based on revenue equivalent sales or production (where applicable) which assumes average realised prices remain unchanged from FY18. Figures are converted
      to per share basis by dividing FY18 and FY19e revenue equivalent sales or production (where applicable) by the weighted average number of shares for
      FY18 (5,159 million) and H1 FY19 (5,079 million) respectively.

(25)  South32's interest in South Africa Energy Coal is accounted at 100% until Broad-Based Black Economic Empowerment (B-BBEE) vendor loans are repaid.

(26)  Payable zinc equivalent (kt) was calculated by aggregating revenues from payable silver, lead and zinc, and dividing the total Revenue by the price of zinc. FY18
      realised prices for zinc (US$3,185/t), lead (US$2,463/t) and silver (US$16.6/oz) have been used for FY18, FY19e and FY20e. Zinc equivalent is used to compare
      Cannington with the recently acquired Hermosa project which is currently reported in zinc equivalent terms.

(27)  Operating unit cost is Revenue less Underlying EBITDA, excluding third party sales, divided by sales volumes. Operating cost is Revenue less Underlying EBITDA
      excluding third party sales. Additional manganese disclosures are included in footnotes 39 and 44.

(28)  FY19 prior Operating unit cost guidance included royalties (where appropriate) and the influence of exchange rate assumptions, and were predicated on various
      assumptions for FY19, including: an alumina price of US$411/t; an average blended coal price of US$149/t for Illawarra Metallurgical Coal; a manganese ore price
      of US$6.20/dmtu for 44% manganese product; a nickel price of US$6.92/lb; a thermal coal price of US$93/t (API4) for South Africa Energy Coal; a silver price of
      US$17.58/troy oz; a lead price of US$2,406/t; a zinc price of US$3,066/t; an AUD:USD exchange rate of 0.76; a USD:ZAR exchange rate of 13.43; a USD:COP
      exchange rate of 2,927; and a reference price for caustic soda; all of which reflected forward markets as at June 2018 or our internal expectations.

(29)  FY19 new Operating unit cost guidance includes royalties (where appropriate) and the influence of exchange rates, and includes various assumptions for FY19,
      including: an alumina price of US$443/t; an average blended coal price of US$173/t for Illawarra Metallurgical Coal; a manganese ore price of US$6.58/dmtu for
      44% manganese product; a nickel price of US$5.47/lb; a thermal coal price of US$92/t (API4) for South Africa Energy Coal; a silver price of US$15.06/troy oz; a
      lead price of US$2,023/t (gross of treatment and refining charges); a zinc price of US$2,587/t (gross of treatment and refining charges); an AUD:USD exchange
      rate of 0.72; a USD:ZAR exchange rate of 14.02; a USD:COP exchange rate of 3,096; and a reference price for caustic soda; all of which reflected forward
      markets as at January 2019 or our internal expectations.

(30)  On 24 September 2018, we announced that the Constitutional Court of Colombia had issued its final ruling on our application to annul its decision regarding the
      alleged health and environmental impacts of our Cerro Matoso operation on the surrounding communities. The Court annulled those orders requiring Cerro Matoso
      to pay direct financial compensatory damages to community members and establish an ethnic development fund. The orders requiring Cerro Matoso to provide
      ongoing health care to community members alleging health impacts, and to submit to a new consultative environmental licensing process, were not annulled.

(31)  Third party products and services sold comprise US$33M for aluminium, US$16M for alumina, US$241M for coal, US$129M for freight services, US$61M for
      aluminium raw materials and US$7M for manganese. Underlying EBIT on third party products comprise nil for aluminium, US$3M for alumina, US$27M for coal,
      (-US$3M) for freight services, US$1M for aluminium raw materials and nil for manganese.

(32)  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.

      announcement.

(35)  South Africa Energy Coal Revenue includes domestic and export sales Revenue.

(36)  Illawarra Metallurgical Coal Revenue includes metallurgical coal and energy coal sales Revenue.

(37)  The quarterly 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 minus one or "M-1") was US$6.98/dmtu in H1 FY19.

(38)  Volumes and realised prices do not include any third party trading that may be undertaken independently of equity production. Realised ore prices are calculated
      as external sales Revenue less freight and marketing costs, divided by external sales volume. Realised alloy prices are calculated as sales Revenue, including
      sinter Revenue, divided by alloy sales volume. Ore converted to sinter and alloy, and sold externally, is eliminated as an intracompany transaction.

(39)  Manganese Australia H1 FY19 average manganese content of external ore sales was 45.8% on a dry basis (H1 FY18: 46.1%). 95% of H1 FY19 external
      manganese ore sales (H1 FY18: 94%) were completed on a CIF basis. H1 FY19 realised FOB ore prices and Operating unit costs have been adjusted for freight
      and marketing costs of US$25M (H1 FY18: US$21M), consistent with our FOB cost guidance.

(40)  FOB ore operating unit cost is Revenue less Underlying EBITDA, freight and marketing costs, divided by ore sales volume. Alloy operating unit cost is Revenue
      less Underlying EBITDA divided by alloy sales volumes and includes costs associated with sinter sold externally.

(41)  Revenues associated with sales from GEMCO to TEMCO are eliminated as part of the consolidation. Internal sales occur on a commercial basis.

(42)  The quarterly sales volume weighted average of the Metal Bulletin 37% manganese lump ore index (FOB Port Elizabeth, South Africa) on the basis of a one month
      lag to published pricing (Month minus one or "M-1") was US$5.91/dmtu in H1 FY19.

(43)  Volumes and prices do not include any third party trading that may be undertaken independently of equity production. Realised ore prices are calculated as
      external sales Revenue less freight and marketing costs, divided by external sales volume. Realised alloy prices are calculated as sales Revenue, divided by 
      alloy sales volume. Ore converted to sinter and alloy, and sold externally, is eliminated as an intracompany transaction. Manganese ore sales are 
      grossed-up to reflect a 60% accounting effective interest.

(44)  Manganese South Africa H1 FY19 average manganese content of external ore sales was 40.3% on a dry basis (H1 FY18: 40.3%). 71% of H1 FY19 external
      manganese ore sales (H1 FY18: 68%) were completed on a CIF basis. H1 FY19 realised FOB ore prices and operating costs have been adjusted for freight and
      marketing costs of US$20M (H1 FY18: US$16M), consistent with our FOB cost guidance.

(45)  FOB ore operating unit cost is Revenue less Underlying EBITDA, freight and marketing costs, divided by ore sales volume. Alloy operating unit cost is Revenue
      less Underlying EBITDA divided by alloy sales volumes.

(46)  Revenues associated with sales from Hotazel Manganese Mines (HMM) to Metalloys are eliminated as part of the consolidation. Internal sales occur on a
      commercial basis.

(47)  Consistent with the presentation of South32's segment information, South Africa Manganese ore production and sales have been reported at 60%. 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 interest 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%.

(48)  Volumes and prices do not include any third party trading that may be undertaken independently of equity production. Cerro Matoso realised nickel sales price is
      inclusive of by-products. Realised sales price is calculated as sales Revenue divided by sales volume.

(49)  Cannington Operating unit cost is Revenue less Underlying EBITDA divided by ore processed. Periodic movements in finished product inventory may impact
      operating unit costs as related marketing costs may change.

Figures in Italics indicate that an adjustment has been made since the figures were previously reported.

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 2018 were authorised for issue in accordance with a resolution of the
Directors on 14 February 2019.

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 4 Segment information.

2. Basis of preparation
   The half year consolidated financial statements are a general purpose condensed financial report which:

  -  Have been prepared in accordance with AASB 134 Interim Financial Reporting, IAS 34 Interim Financial Reporting and the
     Corporations Act
  -  Have been prepared on a historical cost basis, except for derivative financial instruments and certain other financial assets and
     liabilities which are required to be measured at fair value
  -  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 2018 annual consolidated financial statements, except for the change in accounting standards set out in note 3 New
     standards and interpretations which became effective on 1 July 2018 without restatement of prior years
   
   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 2018.

   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 2018. 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.

   The following exchange rates relative to the US dollar have been applied in the half year consolidated financial statements.

3. New standards and interpretations
   New accounting standards and interpretations effective from 1 July 2018
   The Group has changed some of its accounting policies as a result of new or revised accounting standards which became effective
   for the annual reporting period commencing on 1 July 2018. New policies and standards are:
   
   AASB 9 Financial Instruments

   The Group has adopted AASB 9 Financial Instruments with a date of initial application of 1 July 2018. The nature and impact of the
   key changes to the Group's accounting policies resulting from the adoption of AASB 9 are summarised below.

   (i) Classification and measurement of financial assets and financial liabilities

   AASB 9 contains three principal classification categories for financial assets: measured at amortised cost, fair value through Other
   Comprehensive Income (FVOCI) and fair value through profit or loss (FVTPL). The classification of a financial asset is based on
   the cash flow characteristics and the business model used for the management of the financial asset. AASB 9 eliminates the
   previous AASB 139 Financial Instruments: Recognition and Measurement financial asset classification of held to maturity, loans
   and receivables and available for sale.

   The adoption of AASB 9 has not had a significant impact on the Group's accounting policies for financial liabilities as
   AASB 9 largely retains the existing requirements in AASB 139 for the classification and measurement of financial liabilities.

   (ii) Impairment of financial assets

   AASB 9 replaces the 'incurred loss' model in AASB 139 with an expected credit loss model. The new impairment model applies to
   financial assets measured at amortised cost, contract assets and debt investments classified as FVOCI, but not to investments in
   equity instruments. Under AASB 9, credit losses are recognised earlier than under AASB 139.

   (iii) Transition

   For transition, the Group has elected to apply the limited exemption in AASB 9 relating to the classification, measurement and
   impairment requirements for financial assets and accordingly has not restated comparative periods. Any resulting adjustments to
   carrying values in the opening balance sheet have been recognised in opening retained earnings as at 1 July 2018.
   
   The following table summarises the impact, net of tax, of transition to AASB 9 on retained earnings at 1 July 2018.

   US$M                                                                             Impact from adopting AASB 9 on 1 July 2018

   (1) The investment in unit trusts held by the South32 South Africa Energy Coal Rehabilitation Trust Fund does not meet the definition of 
       an equity instrument under AASB 9. These investments are therefore classified as investments held at FVTPL (FY18: Available for sale).

   (1) Trade and other receivables and loans to equity accounted investments are reduced by the recognition of an impairment provision as a result of applying the
       expected credit loss model under AASB 9, US$1 million each. The impact was recognised in opening retained earnings at 1 July 2018 on transition to AASB 9.
   (2) Investments in equity instruments designated as FVOCI represent investments that the Group intends to hold for long-term strategic purposes. As permitted by
       AASB 9, on an instrument by instrument basis, the Group has elected to designate these investments as held at FVOCI at the date of initial application.
   (3) Other investments held at FVTPL which were previously classified as available for sale, are not equity instruments and are therefore unable to be designated as
       investments held at FVOCI.

   AASB 15 Revenue from Contracts with Customers
   The Group adopted AASB 15 Revenue from Contracts with Customers from 1 July 2018 using the modified retrospective approach
   where transitional adjustments are recognised in retained earnings. Therefore, the comparative information has not been restated
   and continues to be reported under AASB 118 Revenue.
   
   The impact of the change in accounting policy did not have a material impact on the amount of revenue recognised as the transfer
   of risk and rewards under AASB 118 is equivalent with the fulfilment of the performance obligation to deliver commodities. Any
   differences arising from freight services for Cost, Insurance and Freight (CIF) contracts are immaterial in the current and
   comparative periods.
   
   Revenue will be recognised net of treatment and refining charges (previously recognised on a gross basis with treatment and
   refining charges included as a separate expense).

4. 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.

   Certain 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:

   All operations are operated or jointly operated by the Group except Brazil Alumina, which is operated by Alcoa.

   (b) Segment results
   Segment performance is measured by Underlying EBIT and Underlying EBITDA. Underlying EBIT is profit before net finance cost,
   tax and other earnings adjustment items including impairments. Underlying EBITDA is Underlying EBIT, before depreciation and
   amortisation. A reconciliation of Underlying EBIT, Underlying EBITDA and the Group's consolidated profit after tax is set out on the
   following pages. Segment revenue is measured on the same basis as in the Consolidated Income Statement.

   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.

   Total assets and liabilities for each operating segment represent operating assets and liabilities which predominantly exclude the
   carrying amount of equity accounted investments, cash, interest bearing liabilities and tax balances. The carrying amount of
   investments accounted for using the equity method represents the balance of the Group's investment in equity accounted
   investments, with no adjustment for cash, interest bearing liabilities and tax balances of the equity accounted investment.

   Revenue recognition policy applicable from 1 July 2018

   The Group has applied AASB 15 using the modified retrospective method. The impact of changes in accounting standards are
   disclosed in note 3 New standards and interpretations.

   Revenue is measured based on the consideration specified in the contract with a customer and excludes amounts collected on
   behalf of third parties. Revenue is not reduced for royalties and other taxes payable from group production.

   The following is a description of the principal activities from which the Group generates its revenue.

   Revenue from the sale of commodities
   The Group primarily sells the following commodities: alumina, aluminium, energy coal, metallurgical coal, manganese ore,
   manganese alloy, ferronickel, silver, lead and zinc. The sales of these commodities are considered to be performance obligations
   as they are the contractual promises by the Group, to transfer distinct goods to customers.

   The transaction price allocated to each performance obligation is recognised as the performance obligation is satisfied. Satisfaction
   occurs when control of the promised commodity is transferred to the customer.

   For the sale of commodities, revenue is therefore recognised at a point in time, net of treatment and refining charges (where
   applicable). The majority of the Group's sales agreements specify that title passes on the bill of lading date, which is the date the
   commodity is delivered to the shipping agent, and the Group no longer has control over the commodity. For these sales, revenue is
   recognised on the bill of lading date. For certain sales (principally energy coal sales to adjoining power stations), title passes, and
   revenue is recognised when the goods have been delivered.

   For certain commodities, the sales price is determined on a provisional basis at the date of sale and adjustments to the sales price
   subsequently occur based on movements in quoted market or contractual prices up to the date of final pricing. The period between
   provisional invoicing and final pricing is up to 180 days. Revenue on provisionally priced sales is recognised based on the
   estimated fair value of the total consideration receivable. The revenue adjustment mechanism embedded within provisionally priced
   sales arrangements has the characteristics of a commodity derivative. Accordingly, the fair value of the final sales price adjustment
   is re-estimated continuously and changes in fair value are disclosed separately as 'Other' revenue. In all cases, fair value is
   estimated by reference to forward market prices.

   Revenue from the provision of freight services
   The Group sells most of its commodities on either Free On Board (FOB) or CIF Incoterms. In the case of CIF Incoterms, the Group
   is responsible for shipping services after the date at which control of the commodities passes to the customer at the port of loading.
   The provision of shipping services in these types of arrangements are a distinct service (and therefore a separate performance
   obligation) to which a portion of the transaction price should be allocated and recognised over time as the shipping services are
   provided. The Group also provides third party freight services which are recognised as the shipping service is provided.

   The Group does not disclose sales revenue from freight services separately as it does not consider this necessary in order to
   understand the impact of economic factors on the Group.

(1) The segment information reflects the Group's interest in the manganese operations and is presented on a proportional consolidation basis, which is the measure used by the Group's management to 
    assess their performance. The manganese operations are equity accounted in the half year consolidated financial statements. The statutory adjustment column reconciles the proportional consolidation
    to the equity accounting position.

(1) The segment information reflects the Group's interest in the manganese operations and is presented on a proportional consolidation basis, which is the measure used by the Group's management to assess 
    their performance. The manganese operations are equity accounted in the half year consolidated financial statements. The statutory adjustment column reconciles the proportional consolidation to the equity 
    accounting position.
(2) A portion of Group production may be provisionally priced at the date revenue is recognised. For the half year ended 31 December 2017 there was no requirement under AASB 118 to separate out and disclose 
    provisional price movements. Presentation of revenue is gross of treatment and refining charges.
(3) Third party products and services sold comprise US$148 million for aluminium, US$48 million for alumina, US$128 million for coal, US$85 million for freight services and US$54 million for aluminium raw 
    materials. Underlying EBIT on third party products and services comprise US$6 million for aluminium, nil for alumina, nil for coal, (US$1) million for freight services and nil for aluminium raw materials.

Investments in equity instruments - designated as FVOCI
At 1 July 2018, on an instrument by instrument basis, the Group has elected under AASB 9 to designate investments in equity
instruments as FVOCI as they represent investments that the Group intends to hold for long-term strategic purposes. In FY18 these
investments were classified as available for sale (refer to note 3 New standards and interpretations).

Other investments - held at FVTPL
The investment in unit trusts held by the South32 South Africa Energy Coal Rehabilitation Trust Fund does not meet the definition
of an equity instrument under AASB 9. These investments are therefore classified as investments held at FVTPL (FY18: Available
for sale). On transition to AASB 9 (1 July 2018), a net gain of US$12 million was transferred from the financial asset reserve to
retained earnings.

Measurement of fair value
The following table shows the Group's financial assets and liabilities carried at fair value with reference to the nature of valuation
inputs used:

Level 1 Valuation is based on unadjusted quoted prices in active markets for identical financial assets and liabilities.
Level 2 Valuation is based on inputs (other than quoted prices included in Level 1) that are observable for the financial asset or
        liability, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices).
Level 3 Valuation includes inputs that are not based on observable market data.

Sensitivity analysis
The carrying amount of financial assets and liabilities that are valued using inputs other than observable market data are calculated
using appropriate valuation models, including discounted cash flow modelling, with inputs such as commodity prices, foreign
exchange rates and inflation. The potential effect of using reasonably possible alternative assumptions in these models, based on
changes in the most significant inputs by 10 per cent while holding all other variables constant, is shown in the following table.

believe that the Half-year Financial Statements of         Statement of Comprehensive Income,

- complying with Australian Accounting Standard          - The Directors' Declaration
  AASB 134 Interim Financial Reporting and the         
  Corporations Regulations 2001.                         The Group comprises South32 Limited (the Company)
                                                         and the entities it controlled at the half-year's end or
                                                         from time to time during the half-year.

Responsibilities of the Directors for the Half-year Financial State ents 

The Directors of the Company are responsible for:

-   the preparation of the Half-year Financial Statements that give a true and fair view in accordance with 
    Australian Accounting Standards and the Corporations Act 2001
-   such internal control as the Directors determine is necessary to enable the preparation of the Half-year 
    Financial Statements that is free from material misstatement, whether due to fraud or error.

Auditor's responsibility for the review of the Half-year Financial Statements     

Our responsibility is to express a conclusion on the Half-year Financial Statements based on our review. 
We conducted our review in accordance with Auditing Standard on Review Engagements ASRE 2410 Review of a 
Financial Report Performed by the Independent Auditor of the Entity, in order to state whether, on the basis 
of the procedures described, we have become aware of any matter that makes us believe that the Half-year 
Financial Statements are not in accordance with the Corporations Act 2001 including: giving a true
fair view of the Group's financial position as at 31 December 2018 and its performance for the half-year 
ended on that date; and complying with Australian Accounting Standard AASB 134 Interim Financial Reporting and 
the Corporations Regulations 2001. As auditor of South32 Limited, ASHE 2410 requires that we comply with the 
ethical requirements relevant to the audit of the annual Financial Report. 

A review of Half-year Financial Statements consists of making enquiries, primarily of persons responsible for 
financial and accounting matters, and applying analytical and other review procedures. A review is 
substantially less in scope than an audit conducted in accordance with Australian Auditing Standards and 
consequently does not enable us to obtain assurance that we would become aware of all significant matters 
that might be identified in an audit. Accordingly, we do not express an audit opinion. 

In conducting our review, we have complied with the independence requirements of the Corporations Act 2001.
