Rio Tinto delivers first half underlying earnings of $2.9 billion

6 August 2015

Rio Tinto chief executive Sam Walsh said "This is a robust set of results, given the tough operating environment. Tier one assets and sound operating capability have delivered stable margins with underlying earnings of $2.9 billion during the half. Post-tax operating cash flows of $4.4 billion more than covered our sustaining capital expenditure of $1.2 billion and dividend payments of $2.2 billion.

"A continued focus on financial and operating discipline delivered first half cost savings of $641 million, representing 85 per cent of our original full year target, which we have now increased to $1.0 billion. We continue to invest in growth, and have reached key milestones in three of our growth projects with the expansion of our Pilbara iron ore infrastructure, first production from our expanded Kitimat aluminium smelter and an agreement to progress the development of the Oyu Tolgoi underground copper mine.

"The early and decisive actions we started taking in 2013 provide a strong base for the business. Our low level of absolute net debt and gearing allow us to maintain our commitment to capital returns in 2015, with
$3.2 billion returned to shareholders in the first half through our progressive dividend and ongoing share buy-back programme. I am pleased to announce an increase in our interim dividend of 12 per cent, in line with our established dividend policy. I should like to thank all of my colleagues for their exceptional efforts in achieving these results. Rio Tinto is well placed to succeed in these volatile times, and we will use our competitive advantages for the benefit of all our stakeholders."

The financial results are prepared in accordance with IFRS and are unaudited. To allow production numbers to be compared on a like-for-like basis, production from asset divestments completed in 2014 have been excluded from Rio Tinto share of production data but assets sold in 2015 remain in comparisons.

¹Underlying earnings is the key financial performance indicator which management uses internally to assess performance. It is presented here to provide greater understanding of the underlying business performance of the Group's operations. Net and underlying earnings relate to profit attributable to the owners of Rio Tinto. Underlying earnings is defined and reconciled to net earnings on page 57.

²Capital expenditure is presented gross, before taking into account any disposals of property, plant and equipment.

³Net debt is defined and reconciled to the balance sheet on page 40.

⁴Gearing ratio is defined as net debt divided by the sum of net debt and total equity at each period end.

2015 interim results demonstrate continued discipline and focus on cash

Revenues and earnings

- Consolidated sales revenues of $18.0 billion in the first half, $6.4 billion lower than the same period of last year, reflecting a $7.1 billion reduction due to the decline in commodity prices.

- EBITDA¹ margin of 38 per cent, compared with 41 per cent in 2014 first half.

- Underlying earnings of $2.9 billion, $2.2 billion lower than 2014 first half, with cost improvements, lower energy costs and positive currency movements offsetting nearly 40 per cent of the $3.6 billion (post-tax) impact of lower prices.

- Underlying earnings per share of 159.1 US cents.

- Net earnings of $0.8 billion reflect non-cash exchange rate and derivative losses of $1.3 billion, impairment charges of $0.4 billion, mainly related to Energy Resources of Australia, legacy remediation costs of $0.2 billion and general restructuring and headcount reduction costs of $0.1 billion.

Production

- Delivered strong operational performances in iron ore, bauxite, hard coking coal and aluminium.

Cash flow and balance sheet

- Achieved $0.6 billion of sustainable operating cash cost improvements (including exploration and evaluation savings).

- Generated net cash from operating activities of $4.4 billion, as lower taxes paid and stable working capital in period partly offset the impact of lower prices.

- Tight management of trade working capital generated a $30 million inflow of cash in 2015 first half, compared with a $0.8 billion outflow in 2014 first half.

- Reduced capital expenditure by $1.4 billion to $2.5 billion, including $1.2 billion of sustaining capex, which reflected the completion of major projects and continued capital discipline.

- Maintained a strong balance sheet with net debt increasing by $1.2 billion in the six month period to $13.7 billion at 30 June 2015, resulting in net gearing of 21 per cent.

Capital returns

- Returned $3.2 billion to shareholders in 2015 first half including the 2014 final dividend of $2.2 billion and $1.0 billion of share buy-backs, comprising $0.4 billion off-market in Rio Tinto Limited and
$0.6 billion on-market in Rio Tinto plc. In July, a further $0.2 billion of Rio Tinto plc shares were purchased as part of the ongoing programme.

- Increased interim dividend per share by 12 per cent to 107.5 US cents, in line with our policy of setting the interim dividend at half of the total dividend per share for the prior year.

2015 guidance

- Retain tight capital discipline with a focus on cash generation and sustainable returns.

§ Operating cash cost improvement (including exploration and evaluation savings) for 2015 full year is increased from $750 million to $1.0 billion.

§ Capital expenditure is expected to decline to around $5.5 billion in 2015 and less than
$6.0 billion in 2016. Guidance for 2017 remains at around $7.0 billion. Each year includes around $2.5 billion of sustaining capex.

§ Share buy-back programme is ongoing with $1.0 billion of Rio Tinto plc shares expected to be purchased in the second half of 2015.

§ Production guidance is unchanged from the Second Quarter Operations Review.

¹EBITDA margin is defined as Group underlying EBITDA divided by Product Group total revenues as per the Financial Information by Business Unit on page 10 where it is reconciled to profit on ordinary activities before finance items and taxation.

Economy and commodities

Context

As expected at the start of the year, the macro environment and commodity outlook facing the mining industry has been challenging. Commodity prices are under pressure, in some cases falling to levels not seen since 2009 in the aftermath of the Global Financial Crisis. Moderating Chinese demand, continued supply growth and downward shifts in industry cost curves are all contributing to weaker markets. Global macroeconomic risks have also added to short-term volatility, and China's equity market correction and Greece's debt negotiations have resulted in concerns of financial markets impacting commodity trading.

As with all cycles, we expect the current cyclical weakness will pass as global economic growth picks up and commodity markets rebalance. However, the recovery will be characterised by slower commodity demand growth compared to the past decade and a likely continued focus on productivity and costs over capital project development. This is the industry's "New Normal", in which producers at the lower end of the cost curve will maintain their competitive advantage, but higher cost producers will be exposed.

Global economy

Since 2011, the global economy has been following a stable, but relatively subdued, growth pattern, with GDP expanding at around 3.5 per cent each year. All signs so far show that this is extending to 2015.

The recovery is consolidating in developed economies but is yet to lead to a noticeable strengthening in global trade. This is holding back growth in developing economies, which has faded somewhat recently. Without strong external support, China's growth has also been more exposed to its slowing property and construction sector. We expect reported Chinese growth of around 7 per cent in 2015, down from 7.4 per cent in 2014. China's government has responded to the softer macroeconomic conditions with a range of policies aimed at supporting growth in the near term. This has already resulted in improvements in housing sales, although levels of housing stock remain high in smaller cities. Chinese household consumption has also picked up, supported by healthy income growth.

Resumption of work on public infrastructure construction also appears to be picking up - this should help to further stabilise the economy in the second half of the year. The recent equity correction is clearly negative for sentiment but real economy effects will likely be minimal given the short duration of the rally that began in November 2014.

The strengthening of the US dollar, driven by higher US interest rate expectations, has been at the expense of commodity-related exchange rates such as the Australian and Canadian dollars. This has moderated margin pressures on producers via USD denominated cost reductions.

Commodities

China's crude steel production run-rate has been around 815 million tonnes per annum so far in 2015, a slight decrease from 2014 levels. Domestic consumption of steel in China is maturing, but taking into account rising exports of steel as well as steel-containing goods, we continue to project long term growth in Chinese crude steel production, reaching around 1 billion tonnes towards 2030.

Reductions in high cost iron ore production have continued over the first half of 2015 with exits for the year likely to reach about 120 million tonnes, with a further 45 million tonnes at risk. New iron ore supply totalling 110 million tonnes is expected to enter the market in 2015. Despite efforts across the industry to cut costs, recent low prices will continue to put pressure on marginal supply.

Aluminium prices started the year strongly with regional premiums at record levels. However, premiums corrected sharply during the second quarter, falling back towards long-term historical averages. With London Metal Exchange (LME) prices also sliding slightly through the year about 40 per cent of smelters across the industry had returned to a loss-making position by the middle of 2015.

Indonesia's bauxite ore export ban remains in place and the development of local refining capacity is progressing slowly. Meanwhile, high prices have induced the development of new supply from Malaysia.

Copper supply growth has been slower than the market had anticipated. However as several large projects continue to ramp-up, the weaker demand and downward shift in the industry cost curve has kept pressure on prices.

Thermal and metallurgical coal prices have continued along the declining trend they followed through most of 2014. Global supply continues to expand rather than contract as widespread cost reduction initiatives across the industry have resulted in additional tonnes being placed into the market. In both products the influence of Chinese supply has also been key, resulting in reduced net-import levels.

Titanium dioxide prices have remained under pressure, with the industry continuing to absorb feedstock inventories incentivised from the previous period of high prices.

The downward trend in the commodity cycle is highlighted by recent declining trends of exploration and capital expenditure in Australia, down nine and 13 per cent respectively in the first quarter compared with the previous year. First quarter shipments of heavy mobile equipment from the major manufacturers were lower than at any time in the prior ten years.

Prices

The effect of price movements on all major commodities in 2015 first half was to decrease underlying earnings by $3,620 million compared with 2014 first half. A table of prices and exchange rates is included on page 56.

The average Platts price for 62 per cent iron Pilbara fines was 46 per cent lower on average compared with 2014 first half while hard coking coal benchmark prices were 14 per cent lower and thermal coal spot prices averaged 17 per cent lower. Average copper and gold prices were down 14 and seven per cent respectively, while LME aluminium prices averaged two per cent higher.

Exchange rates

Compared with 2014 first half, the US dollar, on average, strengthened by 14 per cent against the Australian dollar and by 11 per cent against both the Canadian dollar and the South African rand. The effect of all currency movements was to increase underlying earnings relative to 2014 first half by $847 million.

Volumes

Volumes enhanced earnings by $79 million compared with 2014 first half. Increased volumes were achieved primarily in iron ore, with the increase in capacity at the Pilbara ports and mines. These offset volume declines in copper, mainly at Rio Tinto Kennecott where the current focus is on de-weighting and de-watering the east wall of Bingham Canyon, and in titanium dioxide feedstocks, where production continued to be aligned with market demand.

Energy

Lower input energy prices during the period improved underlying earnings by $163 million compared with the first half of 2014 as the price of oil fell significantly to an average $58 per barrel during the first half of 2015.

Cash costs, exploration and evaluation

Rio Tinto made further strong progress on its cost reduction programme and has now achieved
$5.4 billion pre-tax ($3.8 billion post-tax) in total operating cash cost improvements and reductions in exploration and evaluation expenditure compared with the 2012 base.

In 2015 first half, the Group realised $0.6 billion pre-tax ($0.5 billion post tax) in operating cash cost savings and reductions in exploration and evaluation spend. This was in addition to the $4.8 billion
pre-tax ($3.3 billion post-tax) achieved in 2013 and 2014.

The Group continued to refine its exploration and evaluation spend, building on the savings achieved in 2014 whilst progressing the highest priority projects. In 2015 first half, approximately 37 per cent of this expenditure was incurred by the Copper & Coal group, five per cent by Iron Ore, 22 per cent by Diamonds & Minerals and 36 per cent by central exploration on greenfield programmes.

Tax / non-cash / interest / other

The 2015 first half effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 28 per cent compared with 30 per cent in 2014 first half. The decreased rate was attributable to the absence of the Australian Minerals Resource Rent Tax (MRRT) which was repealed in the second half of 2014. The Group expects an underlying effective tax rate of approximately 28 to 30 per cent in 2015.

The Group interest charge (net of tax) of $146 million was consistent with 2014 first half.

Items excluded from underlying earnings

Total net impairment charges of $421 million were recognised in 2015 first half.

On 11 June 2015, Rio Tinto announced that it did not support any further study or development of Ranger 3 Deeps, due to the project's economic challenges, and, as indicated at that time, has recognised a non-cash impairment of $262 million (net of non-controlling interests and tax) relating to its shareholding in Energy Resources of Australia.

A charge of $242 million has been recognised for the remediation of the Holden mine in Washington State. This legacy property was acquired through the Alcan acquisition in 2007.

Non-cash exchange and derivative losses of $1,306 million arose primarily on US dollar debt in non-US dollar functional currency Group companies, intragroup balances, and on the revaluation of certain derivatives which do not qualify for hedge accounting. The exchange losses are largely offset by currency translation gains recognised in equity and the quantum of US dollar debt, which will be repaid from US dollar sales receipts and US dollar divestment proceeds, is therefore unaffected.

Cash flow

Net cash generated from operating activities of $4.4 billion was 19 per cent lower than 2014 first half, mainly reflecting the impact of lower prices, partially offset by cash cost improvements, stable current working capital movements and lower tax payments in line with lower profits. First half operating cash flows more than covered the $1.2 billion of sustaining capital expenditure and 2014 final dividend of
$2.2 billion, leaving $1.0 billion to invest in growth capital.

Due to the timing of payments, working capital tends to be weighted more favourably to the second half of the year. Working capital cash inflows of $30 million in the first half of 2015 therefore compare favourably with the cash outflows of $795 million and $678 million in 2014 and 2013, respectively. This inflow arose from continued work reducing inventory and receivables. It was, however, offset by a reduction in payables, mostly from actions taken to reduce capital and operating expenditures. In balance sheet terms, working capital increased by $273 million from the impact of non-cash working capital movements.

Purchase of property, plant and equipment and intangible assets declined by $1.4 billion or 35 per cent to $2.5 billion in 2015 first half. Major capital projects included the completion of the expansion of the Pilbara iron ore infrastructure to 360 Mt/a and the expansion of the Kitimat aluminium smelter in British Columbia, where first metal was poured in June 2015.

Dividends paid in 2015 first half of $2.2 billion reflect the 12 per cent increase in the 2014 total dividend per share paid in April 2015. Share repurchases totalled $1.0 billion in 2015 first half.

In 2015 first half, net proceeds from disposal of subsidiaries, joint ventures and associates related primarily to amounts received following the disposal of the 25.7 per cent interest in SouthGobi Resources by Turquoise Hill Ltd on 23 April 2015.

In 2014 first half, net proceeds from the disposal of subsidiaries, joint ventures and associates of
$1.0 billion reflected the sale of the Group's interests in the Clermont thermal coal mine, while proceeds from the issue of equity to holders of non-controlling interests of $1.2 billion related to the Turquoise Hill Resources rights offering.

Balance sheet

Net debt (see page 40) increased from $12.5 billion at 31 December 2014 to $13.7 billion at 30 June 2015, mainly reflecting the $1.0 billion share buy-back. Net debt to total capital (net gearing) was 21 per cent at 30 June 2015 (31 December 2014: 19 per cent) and interest cover was nine times, down from 12 times coverage in the 2014 first half. The increase in net gearing was partly driven by the $4.0 billion decline in shareholders' equity from 31 December 2014 to 30 June 2015 mainly attributable to weaker Australian and Canadian currencies along with the share buy-back.

Adjusted total borrowings at 30 June 2015 were $24.8 billion. The weighted average cost of total borrowings was approximately three per cent and the weighted average maturity was around eight years. The maximum amount, within non-current borrowings, maturing in any one calendar year was $3.3 billion. At 30 June 2015, approximately two thirds of Rio Tinto's total borrowings were at fixed interest rates.

In 2015 first half, the Group repaid $1.3 billion of borrowings. Cash and cash equivalents at 30 June 2015 were $11.2 billion (31 December 2014: $12.4 billion), which includes the proceeds of the $1.2 billion in 10 year fixed rate notes issued in June 2015 which were used for the early redemption of 2016 notes in July 2015. The Group has a further $0.5 billion of borrowings due to mature in the second half of 2015 which it expects to repay from cash.

Profit for the period

Net earnings and underlying earnings, which are the focus of the commentary in this report, refer to amounts attributable to the owners of Rio Tinto. Net profit attributable to the owners of Rio Tinto in 2015 first half totalled $806 million (2014 first half: $4,402 million). The Group recorded a profit in 2015 first half of $799 million (2014 first half: $4,285 million) of which a loss of $7 million (2014 first half: loss of
$117 million) was attributable to non-controlling interests.

Dividends

The aim of Rio Tinto's progressive dividend policy is to maintain or increase the US dollar value of ordinary dividends per share. The rate of the total dividend, in US dollars per share, is determined taking into account the results for the past year and the outlook. The interim dividend is set at one half of the total dividend per share for the previous year.

Dividends are determined in US dollars. Rio Tinto plc dividends are declared and paid in pounds sterling and Rio Tinto Limited dividends are declared and paid in Australian dollars, converted at exchange rates applicable on 4 August 2015 (the latest practicable date prior to the declaration of the dividend).

Ordinary dividend per share	2015 interim	2014 interim	2014 full year
Rio Tinto Group
US cents	107.5	96.00	215.00
Rio Tinto plc
UK pence	68.92	56.90	134.88
Rio Tinto Limited
Australian cents	144.91	103.09	256.07

Rio Tinto Limited shareholders will be paid dividends which are fully franked. The board expects Rio Tinto Limited to be in a position to pay fully franked dividends for the foreseeable future.

Dividends will be paid on 10 September 2015 to holders of ordinary shares and ADRs on the register at the close of business on 14 August 2015. The ex-dividend date for Rio Tinto Limited and Rio Tinto plc ADR holders will be 12 August 2015 and the ex-dividend date for Rio Tinto plc shareholders will be 13 August 2015.

Rio Tinto plc shareholders may elect to receive their dividend in Australian dollars, and Rio Tinto Limited shareholders may elect to receive their dividend in pounds sterling. Currency conversions will be determined by reference to the exchange rates applicable to pounds sterling and Australian dollars five business days prior to the dividend payment date. Currency elections must be registered by 19 August 2015 for Rio Tinto plc shareholders and 20 August 2015 for Rio Tinto Limited shareholders.

ADR holders receive dividends in US dollars, which will be converted from pounds sterling by reference to the exchange rate applicable on 3 September 2015. This is likely to differ from the US dollar determining rate due to currency fluctuations.

As usual, Rio Tinto will operate its Dividend Reinvestment Plans, details of which can be obtained from the Rio Tinto website (www.riotinto.com). The last date for receipt of the election notice for the Dividend Reinvestment Plans for Rio Tinto plc shareholders is 19 August 2015 and for Rio Tinto Limited shareholders is 20 August 2015. Purchases under the Dividend Reinvestment Plan are made on or as soon as practicable after the dividend payment date and at prevailing market prices. There is no discount available.

Capital expenditure (US$ millions)	879	2,069	-58%

The Simandou iron ore project is reported within Diamonds & Minerals, reflecting management responsibility.

Performance

The Iron Ore group's underlying earnings of $2,099 million in 2015 first half were 55 per cent or
$2,584 million down on 2014 first half. This was driven by the impact of lower prices, down 46 per cent, on average, half on half, reducing earnings by $3.2 billion, which were partly offset by higher sales volumes together with a weaker Australian dollar, lower energy costs and the realisation of significant cost savings initiatives.

Pre-tax cash cost improvements in the Iron Ore group were $244 million in 2015 first half and have now delivered $954 million of cumulative savings compared with the 2012 base. This is reflected in a reduction in Pilbara cash unit costs to $16.20 per tonne in 2015 first half, compared with $20.40 per tonne in 2014 first half. Pilbara operations delivered a free on board (FOB) EBITDA margin of 61 per cent in 2015 first half (2014 first half: 70 per cent).

Gross sales revenues for Pilbara operations in 2015 first half of $7,004 million included freight revenue of $372 million (2014 first half: $635 million).

Net cash generated from operating activities of $2,065 million benefited from strong shipments from both the Pilbara and the Iron Ore Company of Canada, combined with lower operating costs through realised cost savings initiatives and improved productivity.

The 58 per cent decline in capital expenditure reflects the completion of the 290 Mt/a mine expansions in 2014 and the recently completed Pilbara infrastructure expansion.

Markets

Approximately 25 per cent of sales in the first half of 2015 were priced with reference to the prior quarter's average index lagged by one month. The remainder was sold either on current quarter average, current month average or on the spot market. Around 55 per cent of 2015 first half Pilbara sales were made on a cost and freight (CFR) basis, with the remainder sold FOB. Achieved average pricing in 2015 first half was $54.40 per wet metric tonne on an FOB basis. This equates to $59.13 per dry metric tonne (assuming an average eight per cent moisture content), which compares with the average Platts price of $56 per dry metric tonne for 62 per cent iron Pilbara fines during the half.

Operations

Global production of 154.3 million tonnes (Rio Tinto share 123.3 million tonnes) was 11 per cent higher than 2014 first half following the successful ramp up to 290 Mt/a in May 2014, and was achieved despite unseasonal weather in the Pilbara throughout the first half, including Tropical Cyclones Olwyn and Quang. Around seven million tonnes of shipping capacity was lost directly at the ports due to the uncharacteristically severe weather.

Iron Ore Company of Canada delivered a very strong first half of production with 8.0 million tonnes of concentrate and pellets (Rio Tinto share 4.7 million tonnes), a 14 per cent increase over 2014 first half. This significant improvement was driven by increased asset reliability and performance and boosted sales by 16 per cent compared with 2014 first half, to 7.4 million tonnes (Rio Tinto share 4.3 million tonnes).

New projects and growth options

The key elements of the 360 Mt/a infrastructure expansion in the Pilbara are complete. The focus is now to ramp up the new equipment to full capacity and generate maximum value from the integrated system. This includes improvements from debottlenecking and productivity enhancements supported by a range of low cost brownfield developments. Around 40 Mt/a of very low-cost brownfield expansions, principally at West Angelas, Nammuldi, Yandicoogina and Brockman mines, were completed in the half, with an average mine production capital intensity of around $9 per tonne.

Steady progress is being made in the testing and verification of AutoHaul, with over 170 journeys covering 25,000 kilometres completed by the end of June 2015.

An investment decision on the development of the Silvergrass mine is expected in 2016.

2015 shipping and production guidance

Due to the weather disruption in the first half of 2015, anticipated shipments were reduced by around seven million tonnes. Accordingly, Rio Tinto revised its expectations for 2015 global shipments to 340 million tonnes (100 per cent basis) from its operations in Australia and Canada.

Aluminium

	First half 2015	First half 2014	Change
Production (Rio Tinto share)
Bauxite (000 tonnes)	21,179	20,188	+5%
Alumina (000 tonnes)	3,821	3,650	+5%
Aluminium (000 tonnes)	1,627	1,627	-

Gross sales revenue (US$ millions)	5,455	5,752	-5%
Underlying EBITDA (US$ millions)	1,688	1,097	+54%
Underlying earnings (US$ millions)	793	373	+113%
Net cash generated from operating activities (US$ millions)	1,556	587	+165%
Capital expenditure (US$ millions)	952	752	+27%

The Gove alumina refinery is on care and maintenance and reported separately from Aluminium within Other Operations.

Performance

The Aluminium group's underlying earnings of $793 million increased 113 per cent compared with 2014 first half, with EBITDA increasing to $1,688 million and integrated operations EBITDA margins improving to 35 per cent. The Aluminium group benefited from continued portfolio optimisation, momentum from cost reduction and productivity improvement initiatives, weaker Australian and Canadian currencies and higher prices, including regional market and product premiums, compared with 2014 first half.

Pre-tax cash cost improvements in the Aluminium group were $145 million in 2015 first half and the group has now delivered $951 million of cumulative savings compared with the 2012 base. This strong performance, combined with reduced working capital levels, helped the group to deliver close to
$1.6 billion of operating cash flow and around $650 million of free cash flow in 2015 first half. Capital expenditure increased by 27 per cent as the expansion of the Kitimat smelter neared completion, with first production taking place in June.

Markets

The 2015 first half cash LME aluminium price averaged $1,783 per tonne, an increase of two per cent on 2014 first half. Market premiums in all regions reached record highs early in 2015 before falling back rapidly during the second quarter. Specifically, in the US, the Mid-West market premium reached
$535 per tonne in the first quarter of 2015, ahead of a dramatic move downward during the second quarter, to complete the first half at $187 per tonne.

Overall, the group achieved an average realised aluminium price of $2,292 per tonne in 2015 first half compared with $2,249 per tonne in 2014 first half. This includes premiums for value-added products (VAP), which represented 59 per cent of primary metal produced in the first half of 2015 and generated attractive product premiums averaging $259 per tonne of VAP sold in 2015 first half on top of physical market premiums.

Bauxite prices remain attractive, underpinned by growing import demand in China. Third party bauxite sales increased 29 per cent in 2015 first half to 13.2 million tonnes (2014 first half: 10.2 million tonnes).

Operations

Bauxite underlying earnings increased by 40 per cent to $273 million in 2015 first half, with FOB EBITDA margins of 51 per cent, driven by the sustained increase in third party sales and stronger pricing. Bauxite production was five per cent higher than the first half of 2014 and set a new first half record, primarily driven by a strong performance at Weipa and Gove's continued ramp up towards an eight million tonne annual run-rate by the fourth quarter of 2015.

Gross sales revenues for bauxite in 2015 first half of $1,013 million included freight revenues of
$93 million (2014 first half: $115 million).

The alumina division recorded a loss of $52 million, which represented a 69 per cent improvement on 2014 first half, attributable to an improvement in volumes, productivity gains, higher pricing and favourable currency movements. Alumina production was up by five per cent compared with the first half of 2014 (excluding production from the Gove refinery which was curtailed in May 2014), reflecting improved productivity at Queensland Alumina and Yarwun.

Primary Metal increased earnings by 70 per cent to $305 million, while earnings from the Pacific Aluminium smelters rose by 61 per cent to $150 million. All operations continued to realise significant cost savings and benefited from favourable prices and currency movements. First half aluminium production was in line with the same period of 2014, despite lower production from Kitimat as it prepared for commissioning of the modernised and expanded low cost smelter.

New projects and growth options

The expanded Kitimat smelter commenced production in June 2015. Kitimat will ramp up towards nameplate capacity of 420 thousand tonnes (a 48 per cent increase over previous nameplate capacity), by early 2016. Once Kitimat is at full production, 80 per cent of the Aluminium group's smelting capacity will be in the lowest cost quartile.

Feasibility studies are progressing as planned for the South of Embley bauxite project, a 22.8 Mt/a, tier one investment opportunity in Cape York, Queensland, with mining costs expected to be in the first quartile. Required regulatory permits are in place and the project is expected to be presented to the board for final approval by the end of 2015.

2015 production guidance

Rio Tinto's share of bauxite, alumina and aluminium production for 2015 is expected to be 43 million tonnes, 8.0 million tonnes and 3.3 million tonnes, respectively.

Copper & Coal

	First half 2015	First half 2014	Change
Production (Rio Tinto share)
Mined copper (000 tonnes)	278.4	323.0	-14%
Refined copper (000 tonnes)	128.0	170.4	-25%

Capital expenditure - excluding EAUs (US$ millions)	399	591	-32%

¹Net cash generated from operating activities excludes the operating cash flows from equity accounted units (Escondida)

but includes dividends from equity accounted units.

Performance

The Copper & Coal group's underlying earnings of $393 million were 40 per cent lower than 2014 first half, but 13 per cent higher when adjusted for movements in prices, exchange rates, energy costs and inflation. This solid performance reflected increased sales volumes from Oyu Tolgoi and the ramp-up of Kestrel, and the delivery of further cash cost savings at Oyu Tolgoi, Escondida and Rio Tinto Coal Australia, partly offset by lower copper and gold volumes at Rio Tinto Kennecott (RTK) where efforts were focused on de-weighting and de-watering the east wall of Bingham Canyon.

Pre-tax cash cost improvements in the Copper & Coal group were $150 million in 2015 first half and have now delivered $1,870 million of cumulative savings compared with the 2012 base.

Despite the challenging market environment, all Copper & Coal operations were free cash flow positive during the period, contributing close to $800 million to the Group. Net cash generated from operating activities of $1.2 billion was $360 million higher than 2014 first half as a result of the higher volumes from Oyu Tolgoi and Kestrel, lower operating costs, higher dividends from Escondida, along with the release of working capital by drawing down inventories. This was partly offset by the adverse impact of prices, along with lower volumes from RTK.

Markets

Average prices in 2015 first half were generally lower than 2014 first half. Copper declined 14 per cent to 268 cents per pound and gold decreased seven per cent to $1,206 per ounce. Thermal and coking coal prices declined further, averaging $63 and $113 per tonne during 2015 first half, respectively.

The total impact of price changes on the Copper & Coal group, including the effects of provisional pricing movements, resulted in a decrease in underlying earnings of $437 million compared with 2014 first half.

At 30 June 2015, the Copper group had an estimated 333 million pounds of copper sales that were provisionally priced at 268 cents per pound. The final price of these sales will be determined during the second half of 2015. This compares with 331 million pounds of open shipments at 31 December 2014, provisionally priced at 288 cents per pound.

Operations - Copper

Mined copper production was 14 per cent lower than 2014 first half, driven by RTK, partly offset by higher production at Escondida and Oyu Tolgoi.

RTK cash flows remain positive despite remediation activities continuing following the pit wall slide in April 2013. This result is supported by the tolling of 166,000 tonnes of third party concentrate through the smelter in 2015 (excluded from reported production figures) and the reduction of unit costs across the business. De-weighting and de-watering of the east wall will continue in the second half of 2015.

Mined copper production at Escondida in the first half was 22 per cent higher than 2014 first half, primarily due to higher grades and throughput. The second half is expected to be impacted by a decline in grades and water availability.

At Oyu Tolgoi, mined copper production was 44 per cent higher than 2014 first half, attributable to higher grades and throughput. Mining has started moving to areas of higher grade ore in the open pit. Oyu Tolgoi's copper production in the second half of 2015 is expected to be higher than the first half.

Operations - Coal

Hard coking coal production was 13 per cent higher than 2014 first half, as a result of improved production rates at Kestrel which continues to ramp up towards nameplate long-wall capacity of around six million tonnes.

Semi-soft coking coal production was five per cent higher than 2014 first half, reflecting mine production sequencing at the Hunter Valley Operations. Thermal coal production was in line with 2014 first half, with increased tonnage at Hail Creek, through a processing plant by-product stream and a strong operational performance, offset by the impact of wet weather in the Hunter Valley. A long-wall changeover at Kestrel is planned for the second half of 2015.

New projects and growth options

On 18 May 2015, the Government of Mongolia, Turquoise Hill Resources and Rio Tinto signed the Underground Mine Development and Financing Plan (UDP) which provides a pathway forward in addressing shareholder matters to restart underground development. Next steps include approval of the underground feasibility study and project financing, as well as securing all necessary permits for operating the underground mine.

At Escondida, the new 152ktpd Organic Growth Project 1 (OGP1) concentrator achieved mechanical completion in the June 2015 quarter and is now in the commissioning phase. The project remains on schedule and within revised budget and approvals.

2015 production guidance

Rio Tinto expects its share of mined copper production to be between 500,000 and 535,000 tonnes and refined copper production to be between 190,000 and 220,000 tonnes.

For coal, Rio Tinto's share of production is expected to be 18 to 19 million tonnes of thermal coal, 3.0 to 3.4 million tonnes of semi-soft coking coal and 7.1 to 8.1 million tonnes of hard coking coal.

The Simandou iron ore project is reported within Diamonds & Minerals, reflecting management responsibility.

Performance

The Diamonds & Minerals group's underlying earnings of $75 million were one per cent lower than 2014 first half, or seven per cent lower excluding the Simandou exploration and evaluation expenditure. Weaker exchange rates boosted earnings by $104 million, which compensated for lower pricing across most products. Softer markets drove down volumes, most notably in titanium dioxide feedstocks following the decision to optimise production to align with market demand. This in turn impacted cash costs, calculated on a unit cash cost of production, despite the fact that in absolute terms, 2015 first half cash operating costs were $228 million lower than 2014 first half, including a $136 million benefit from exchange rate movements.

Net cash generated from operating activities of $306 million was 29 per cent lower than 2014 first half due to lower prices and sales volumes and higher net tax payments.

Capital expenditure declined by $26 million, or ten per cent, to $245 million, following the completion of the modified direct dissolving of kernite (MDDK) process plant at Boron in 2014 and lower spend on the Argyle underground project.

Markets

Titanium dioxide feedstock demand remained weak in the first half of 2015 and prices continue to be under pressure with the industry continuing to absorb feedstock inventories that were incentivised during the previous periods of high prices. The market for zircon continues to stabilise.

Demand for borates has been stable, globally, with increased demand in Asia offset by reduced demand in Europe.

Industry rough diamond prices are also going through a period of market weakness driven by lower demand from India and China, high rough and polished diamond pipeline inventory, and very low trade manufacturing margins.

The uranium market continues to suffer from high inventory levels throughout the supply chain, keeping uranium prices under pressure during the first half of the year.

Operations

Titanium dioxide slag production was 18 per cent lower than in 2014 first half as production continued to be optimised to align with market demand. Two out of nine furnaces are currently idled at Rio Tinto Fer et Titane (RTFT) in Quebec.

Borates production was slightly lower than in 2014 first half which included additional production to build inventory in preparation for the commissioning of the MDDK plant.

Diamonds production increased 18 per cent half on half, with higher volumes at Argyle from the continued ramp up of production from the underground mine offsetting lower carats recovered at Diavik, reflecting lower ore availability as mining progressed through an area of higher dilution in the first quarter and the absence of stockpiled ore which was processed in 2014 first half.

On 26 June 2015, Rio Tinto announced the sale of its interest in the Murowa diamond mine in Zimbabwe.

Salt production was lower than the comparative period in 2014 as a result of weaker demand and optimising production in line with market demand.

Uranium production was 95 per cent higher than 2014 first half when Energy Resources of Australia (ERA) was not processing ore following a leach tank failure in December 2013. On 11 June 2015, Rio Tinto announced that it did not support any further study on the future development of Ranger 3 Deeps due to the project's economic challenges. Production at Rössing was lower than 2014 first half, largely as a result of lower grades and recoveries, partially offset by higher throughput.

New projects and growth options

Work continues on the feasibility study for the Zulti South development at Richards Bay Minerals (RBM), which is expected to maintain the low cost RBM smelter capacity once completed. Due to market conditions, an investment decision is now expected in mid-2016.

The Argyle underground mine development was completed in June and the operation will continue to ramp up production through 2015.

The development of the A21 pipe at Diavik is advancing as planned, with first production still expected in 2018, as crushing of material for dike construction, a critical path, is going very well. This development will provide an important source of incremental supply to maintain existing production levels and leverage spare processing capacity. A21 is estimated to cost $350 million (Rio Tinto share $210 million).

The Simandou project partners are continuing to work towards the completion of a bankable feasibility study, which has been delayed due to the Ebola epidemic in West Africa. Rio Tinto has given notice to the Government of Guinea of a Force Majeure event which under the terms of the Investment Framework would automatically extend the target date for completion of the bankable feasibility study and formation of a consortium of infrastructure investors. The Government of Guinea has not yet recognised the Force Majeure and discussions are continuing.

2015 production guidance

In 2015, Rio Tinto's share of production is expected to be 1.2 million tonnes of titanium dioxide slag, 0.5 million tonnes of boric oxide equivalent and 20 million carats of diamonds.

Rio Tinto's share of uranium production is expected to be approximately five million pounds.

Central exploration expenditure in 2015 first half (post divestments and tax) resulted in a charge to underlying earnings of $56 million and was 19 per cent lower than in 2014, principally driven by divestment inflows.

Price & exchange rate sensitivities

The following sensitivities give the estimated effect on underlying earnings assuming that each individual price or exchange rate moved in isolation. The relationship between currencies and commodity prices is a complex one and movements in exchange rates can affect movements in commodity prices and vice versa. The exchange rate sensitivities quoted below include the effect on operating costs of movements in exchange rates but exclude the effect of the revaluation of foreign currency working capital. They should therefore be used with care.

DIRECTORS' REPORT
for the half year ended 30 June 2015

Review of operations and important events

A detailed review of the Group's operations, the results of those operations during the half year ended 30 June 2015 and likely future developments are given on pages 1 to 21. Important events that have occurred during the period and up until the date of this report are set out below.

On 12 February 2015, the Group announced a proposed US$2 billion capital return programme, comprising the repurchase of a targeted A$500 million of Rio Tinto Limited shares by way of an off-market buy-back tender, and the balance of approximately US$1.6 billion by way of an on-market buy-back of Rio Tinto plc shares.

On 27 February 2015, the Group announced that it would streamline its product groups and corporate functions as part of the continued focus on efficiency and costs. Under the new arrangements, Rio Tinto's world-class portfolio of assets was condensed into four product groups: Aluminium, Copper & Coal, Diamonds & Minerals, and Iron Ore. The new Copper & Coal product group brings Rio Tinto's coal operations alongside the existing Copper portfolio. Copper chief executive Jean-Sébastien Jacques leads the combined product group. Uranium has been added to the Diamonds & Minerals product group, under the leadership of product group chief executive Alan Davies. As a consequence of the restructuring, Energy chief executive Harry Kenyon-Slaney left the Group.

On 24 March 2015, Rio Tinto and joint venture partner Alcoa agreed to terminate a historic State Agreement Act intended to facilitate the mining of bauxite and the development of an alumina refinery in the north Kimberley region, clearing the way for the area to be included in the Kimberley National Park.

On 7 April 2015, Rio Tinto successfully completed its off-market buy-back tender of Rio Tinto Limited shares, which was increased to A$560 million from the indicative A$500 million announced due to strong demand. The buy-back price was A$48.44 per share which represented a discount of 14 per cent to the market price for Rio Tinto Limited shares. Rio Tinto Limited bought back around 11.6 million shares, at an aggregate cost of approximately A$0.6 billion (US$0.4 billion). This represented 2.65 per cent of Rio Tinto Limited's issued capital (0.63 per cent of the Rio Tinto Group's issued capital) at the time. The on-market buy-back of Rio Tinto plc shares, which will continue until the end of the year, will now total approximately US$1.6 billion.

On 11 June 2015, Rio Tinto acknowledged Energy Resources of Australia Ltd's (ERA) release to the Australian Securities Exchange on 11 June 2015, in which ERA announced it had decided it would not proceed with the Final Feasibility Study of the Ranger 3 Deeps project in the current operating environment. Rio Tinto agrees with the decision not to progress the study. After careful consideration, Rio Tinto has determined that it does not support any further study or the future development of Ranger 3 Deeps due to the project's economic challenges. Rio Tinto recognises the importance of ongoing rehabilitation work at the Ranger mine site, which is surrounded by the Kakadu National Park. Rio Tinto is engaged with ERA on a conditional credit facility to assist ERA to fund its rehabilitation program, should additional funding be required beyond ERA's existing cash reserves and the future earnings from processing ore stockpiles.

On 12 June 2015, Rio Tinto announced that it had priced US$1.2 billion of 10-year fixed rate SEC-registered debt securities. The bonds were issued by Rio Tinto Finance (USA) Limited and are fully and unconditionally guaranteed by Rio Tinto plc and Rio Tinto Limited. The notes will pay a coupon of 3.75 per cent and will mature on 15 June 2025.

On 26 June 2015, Rio Tinto announced that it had completed the sale of its 78 per cent interest in Murowa Diamonds and 50 per cent interest in Sengwa Colliery Ltd (Sengwa) to RZ Murowa Holdings Limited. RioZim Limited, an independent Zimbabwean mining company listed on the Zimbabwean Stock Exchange, already holds a 22 per cent interest in Murowa Diamonds and a 50 per cent interest in Sengwa and will assume the overall management of both entities.

Principal risks and uncertainties

The principal risks and uncertainties that could materially affect Rio Tinto's results and operations are set out on pages 14 to 17 of the 2014 Annual report and are listed under the risk factor headings below. The Group's view of its principal risks and uncertainties for the remaining six months of the financial year remains substantially unchanged. There may be additional risks unknown to Rio Tinto and other risks, currently believed to be immaterial, which could turn out to be material. These risks, whether they materialise individually or simultaneously, could significantly affect the Group's business and financial results.

(i) External risks

Commodity prices and global demand for the Group's products are expected to remain uncertain.

Past strong demand for the Group's products in China could be affected by future developments in that country.

Rio Tinto is exposed to fluctuations in exchange rates.

Political, legal and commercial changes in the places where the Group operates.

Community disputes in the countries and territories in which the Group operates.

Increased regulation of greenhouse gas emissions could adversely affect the Group's cost of operations.

Regulations, standards and stakeholder expectations regarding health, safety, environment and community evolve over time and unforeseen changes could have an adverse effect on the Group's social licence to operate, business viability and reputation.

(ii) Strategic risks

The Group's exploration and development of new projects might be unsuccessful.

Rio Tinto may fail to successfully execute divestments and acquisitions.

Large outsourcing programmes may result in exposure to third-party failure, or loss of intellectual property.

(iii) Financial risks

The Group's reported results could be adversely affected by the impairment of assets including goodwill.

Discount rates used in determining provisions and asset valuations may change, causing changes to provisions, asset carrying values and capital allocation.

The Group's liquidity and cash flow expectations may not be realised, inhibiting planned expenditure.

Failure to reduce costs may result in reduced margins.

(iv) Operational risks

Estimates of ore reserves are based on uncertain assumptions that, if changed, could result in the need to restate ore reserves.

Labour disputes could lead to lost production and/or increased costs.

Some of the Group's technologies are unproven and failures could adversely impact costs and/or productivity.

The Group may be exposed to major failures in the supply chain for specialist services, equipment and materials.

Joint ventures, strategic partnerships or non-managed operations may not be successful and may not comply with the Group's standards.

The Group's operations are vulnerable to a range of interruptions, not all of which are covered fully by insurance. One such risk is that of a sustained pandemic. We have experienced this in Guinea in 2014 and in 2015 with Ebola, which has impacted our projects and operations in-country.

The Group depends on the continued services of key personnel.

The Group's costs of close-down, reclamation and rehabilitation could be higher than expected.

Corporate governance

The directors of Rio Tinto believe that highest standards of corporate governance are essential to its pursuit of greater shareholder value and have continued to apply the standards discussed under 'Corporate governance' on pages 53 to 63 of the 2014 Annual report which is available on the Rio Tinto Group website www.riotinto.com.

Publication of half year results

In accordance with the UK Financial Conduct Authority's Disclosure & Transparency Rules and the Australian Securities Exchange Listing Rules, the half year results will be made public and are available on the Rio Tinto Group website.

Auditor's independence declaration

PricewaterhouseCoopers, the auditors of Rio Tinto Limited, have provided the auditor's independence declaration as required under section 307C of the Corporations Act 2001 in Australia. This has been reproduced on page 52 and forms part of this report.

The Directors' report is made in accordance with a resolution of the board.

Basic earnings per share from continuing operations (d)	43.8c	238.2c
Diluted earnings per share from continuing operations (d)	43.5c	237.0c

(a) The impairment charge in the period related primarily to the decrease in carrying value of Energy Resources of Australia Ltd (ERA), following a Rio Tinto Board decision not to support any future study or development of Ranger 3 Deeps. The cash inflows from processing low grade stockpile ore are not expected to be sufficient to meet the cost of rehabilitation and therefore the property, plant and equipment and intangible assets of ERA have been fully impaired, resulting in a US$260 million pre-tax charge.

Other impairment charges during the period reflect challenging economic conditions at Carbone Savoie and an anticipated disposal in the Aluminium portfolio.

In 2014 the pre-tax impairment charge of US$1,142 million related to the Group's aluminium business. As a result of further revisions to future capital required to complete the modernisation project at Kitimat in British Columbia, and related impacts on the project, the recoverable value of the Kitimat cash-generating unit diminished. The consequent fall in fair value less costs of disposal ('FVLCD') below carrying value resulted in a pre-tax impairment charge to property, plant and equipment of US$1,092 million.

Group income statement (continued)

(b) The 2015 gain related mainly to the sale by Turquoise Hill Resources Ltd (TRQ) of 25.7 per cent of its holdings in SouthGobi Resources (SGR) on 23 April 2015. Rio Tinto also sold its 77.8 per cent interest in Murowa Diamonds and 50 per cent interest in Sengwa Colliery Ltd (Sengwa) to RZ Murowa Holdings Limited on 17 June 2015.

In 2014 pre-tax losses of US$362 million arose mainly from further adjustments in respect of contractual obligations for product sales and delivery which remained with the Group following sale of the Group's interest in the Clermont mine on 29 May 2014, and indemnities provided in respect of prior disposals.

(c) Finance costs in the income statement include hedging adjustments and are net of amounts capitalised of US$171 million (30 June 2014: US$263 million).

(d) For the purpose of calculating basic earnings per share, the weighted average number of Rio Tinto plc and Rio Tinto Limited shares outstanding during the period was 1,838.9 million (30 June 2014: 1,848.2 million), being the average number of Rio Tinto plc shares outstanding of 1,409.3 million (30 June 2014: 1,412.9 million), plus the average number of Rio Tinto Limited shares outstanding of 429.6 million (30 June 2014: 435.3 million). The profit figures used in the calculation of basic and diluted earnings per share are the profits attributable to owners of Rio Tinto.

For the purpose of calculating diluted earnings per share, the effect of dilutive securities is added to the weighted average number of shares. This effect is calculated under the treasury stock method.

Reconciliation with Australian Accounting Standards

The Group's financial statements have been prepared in accordance with IFRS as defined on page 50, which differs in certain respects from the version of IFRS that is applicable in Australia, referred to as Australian Accounting Standards ('AAS').

Prior to 1 January 2004, the Group's financial statements were prepared in accordance with UK GAAP. Under IFRS, goodwill on acquisitions prior to 1998, which was eliminated directly against equity in the Group's UK GAAP financial statements, has not been reinstated. This was permitted under the rules governing the transition to IFRS set out in IFRS 1. The equivalent Australian Standard, AASB 1, does not provide for the netting of goodwill against equity. As a consequence, shareholders' funds under AAS include the residue of such goodwill, which amounted to US$558 million at 30 June 2015 (31 December 2014: US$553 million).

Save for the exception described above, the Group's financial statements drawn up in accordance with IFRS are consistent with the requirements of AAS.

Cash and cash equivalents	11,163	12,423
Consolidated net debt	(13,683)	(12,495)

(a) Consolidated net debt is stated net of the impact of certain funding arrangements between EAUs and partially owned subsidiaries (EAU funded balances). This adjustment is required in order to avoid showing borrowings twice in the net debt disclosure, where funding has been provided to an EAU by the Group and subsequently lent by the EAU to a consolidated Group subsidiary.

(b) Total borrowings are combined with other current financial liabilities of US$270 million (31 December 2014: US$20 million) and non-current financial liabilities of US$271 million (31 December 2014: US$124 million) in the balance sheet.

(c) Equity accounted units funded balances are defined as amounts owed by partially owned subsidiaries to equity accounted units, where such funding was provided to the equity accounted unit by the Group.

Fair value disclosure for financial instruments

Except where stated, the information given below relates to the financial instruments of the parent companies and their subsidiaries and joint operations, and excludes those of equity accounted units.

Fair values of financial instruments

The carrying amounts and fair values of all of the Group's financial instruments which are not carried at an amount which approximates their fair value at 30 June 2015 and 31 December 2014 are shown in the following table. The fair values of the Group's cash and loans to equity accounted units approximate their carrying values as a result of their short maturity or because they carry floating rates of interest.

	30 June 2015		31 December 2014
	Carrying value US$m	Fair value US$m	Carrying value US$m	Fair value US$m
Short term borrowings	(4,152)	(4,183)	(2,664)	(2,711)

Derivatives related to net debt (g)	146	-		146		-		-
	3,329	174		228		282		2,645

(a) Valuation is based on unadjusted quoted prices in active markets for identical financial instruments. This category includes listed equity shares and other quoted funds.

(b) Valuation is based on inputs that are observable for the financial instruments; these include quoted prices for similar instruments or identical instruments in markets which are not considered to be active, or inputs, either directly or indirectly based on observable market data.

(c) Valuation is based on inputs for the asset or liability that are not based on observable market data (unobservable inputs).

(d) Other investments, including loans, comprise: cash deposits in rehabilitation funds, government bonds and royalty amounts receivable. The royalty receivables are valued based on an estimate of forward sales subject to the royalty agreement.

(e) Trade receivables includes provisionally priced receivables relating to sales contracts where selling price is determined after delivery to the customer, based on the market price at the relevant quotation point stipulated in the contract. Revenue is recognised on provisionally priced sales based on the forward selling price for the period stipulated in the contract.

(f) Level 3 derivatives consist of derivatives embedded in electricity purchase contracts linked to the LME with terms expiring between 2015 and 2030. The embedded derivatives are measured using discounted cash flows and option model valuation techniques. Long-term embedded derivatives with a fair value of US$263 million at 30 June 2015 are valued using significant unobservable inputs as the term of the derivative extends beyond the forward curve for aluminium.

Aluminium prices are flat lined beyond the market forward curve and increased by projected inflation up to the date of expiry of the contract.

The range of market prices is US$2,243 per metric tonne in 2025 to US$2,540 in 2030.

The other contracts with a fair value of US$14 million at 30 June 2015 are categorised as level three as the market premium assumptions used represent unobservable inputs.

(g) Interest rate and currency interest rate swaps are valued using applicable market quoted swap yield curves adjusted for relevant basis and credit default spreads. Currency interest rate swap valuations also use market quoted foreign exchange rates. A discounted cash flow approach is applied to the cash flows derived from the inputs to determine fair value.

(h) There were no transfers between Level 1 and Level 2 or between Level 2 and Level 3 for the six months to 30 June 2015 or the six months to 30 June 2014.

Fair value disclosure for financial instruments (continued)

Level 3 Financial instruments

The table below shows the summary of changes in the fair value of the Group's Level 3 financial assets and financial liabilities for the six months to 30 June 2015 and the year ended 31 December 2014.

Level 3 Financial assets and liabilities	30 June 2015	31 December 2014
Opening balance	282	461
Currency translation adjustments	(26)	(17)
Losses realised included in:
- Net operating costs	(5)	(8)
Gains unrealised included in:
- Net operating costs	81	18
Total unrealised gains or (losses) transferred to other comprehensive income	11	(5)
Additions	-	8
Disposals/maturity of financial instruments	-	(175)
Closing balance	343	282
Total losses included in the income statement for assets and liabilities	(9)	(11)

Sensitivity analysis in respect of level 3 derivatives

Forward contracts and options whose carrying value are valued using unobservable inputs are calculated using appropriate discounted cash flow and option model valuation techniques.

The most significant of these assumptions relate to long term pricing wherein internal pricing assumptions are used after the 10 year LME curve. A 10 per cent increase in long term metal pricing assumptions would result in a US$75 million (31 December 2014: US$39 million) decrease in carrying value. A 10 per cent decrease in long term metal pricing assumptions would result in a US$19 million (31 December 2014: US$71 million) increase in carrying value.

Other disclosures

Capital commitments at 30 June 2015

Capital commitments, excluding the Group's share of joint venture capital commitments, were US$1,277 million (31 December 2014: US$1,987 million).

The Group's share of joint venture capital commitments was US$649 million (31 December 2014: US$1,113 million).

For Minera Escondida Limitada and Sohar Aluminium Company L.L.C., the Group, along with the other joint venturers, has made various commitments to provide shareholder funding as required, subject to approved thresholds. In particular, Minera Escondida Limitada holds a shareholder line of credit for US$225 million (Rio Tinto share) which is currently undrawn. This line of credit was also available in 2014.

The Group has a commitment to purchase and market a portion (which may be different to the Group's ownership interest) of the output of Sohar Aluminium Company L.L.C., an aluminium smelter in which the Group is a joint venturer. The Group subsequently sells the purchased products to third parties.

Contingent liabilities (subsidiaries and joint operations)

Contingent liabilities, indemnities and other performance guarantees were US$256 million at 30 June 2015 (31 December 2014: US$239 million).

Indemnities and other performance guarantees represent the potential outflow of funds from the Group for the satisfaction of obligations including those under contractual arrangements (for example undertakings related to rehabilitation activities and supplier agreements) not provided for in the balance sheet, where the likelihood of the guarantees or indemnities being called is assessed as possible rather than probable or remote. There were no material contingent liabilities arising in relation to the Group's joint ventures and associates.

There are a number of legal claims currently outstanding against the Group. No material loss to the Group is expected to result from these claims.

Other disclosures (continued)

Contingent assets

The Group has various insurance claims outstanding with reinsurers including claims relating to the Manefay slide at Rio Tinto Kennecott in April 2013. An interim progress payment was received on this claim in 2013. Further receipts are considered probable but the amount cannot currently be reliably estimated.

Related party matters

Purchases relate largely to amounts charged by equity accounted units for toll processing of alumina and purchases of bauxite and aluminium. Sales relate largely to charges for supply of coal to jointly controlled marketing entities for onward sale to third party customers. Details of the Group's principal equity accounted units are given in the 2014 Annual report.

Rio Tinto plc guarantees to pay the Rio Tinto Pension Fund (UK) any contributions due from Group companies participating in that fund, pro rata to its ownership of those companies and subject to certain conditions, in the event that the companies fail to meet their contribution requirements. Furthermore, Rio Tinto plc has in place a guarantee for the Rio Tinto Pension Fund, in the standard form required by the Pension Protection Fund ('PPF'), to cover 105 per cent of the Fund's liabilities measured on the PPF's prescribed assumptions. Other similar guarantees in place include a Rio Tinto plc guarantee to the Rio Tinto 2009 pension fund, with no limit on liabilities.

In February 2011 an agreement between Alcan Holdings Switzerland and the Alcan Schweiz pension fund was executed whereby the funding deficit as at 31 December 2010 in relation to the pensioner population will be funded by Alcan Holdings Switzerland over a six year period.

Events after the balance sheet date

Share buy-back programme

In July, a further US$0.2 billion of Rio Tinto plc shares were purchased as part of the ongoing share buy-back programme. The programme is ongoing in the second half of 2015.

Rio Tinto corporate bonds repurchase

On 11 July Rio Tinto Finance (USA) Limited repurchased US$1.2 billion of own issued corporate bonds, which had original maturity dates of May and September 2016.

Other than the items noted above, no events were identified after the balance sheet date which could be expected to have a material impact on the consolidated financial statements.

Basis of preparation

The condensed consolidated interim financial statements included in this interim report have been prepared in accordance with International Accounting Standard ('IAS') 34 'Interim financial reporting' as adopted by the European Union ('EU'), the Disclosure and Transparency Rules ('DTR') of the Financial Conduct Authority ('FCA') applicable to interim financial reporting and an Order under section 340 of the Australian Corporations Act 2001 issued by the Australian Securities and Investments Commission on 15 May 2015.

These condensed interim financial statements represent a 'condensed set of financial statements' as referred to in the DTR issued by the FCA. Accordingly, they do not include all of the information required for a full annual financial report and are to be read in conjunction with the Group's annual financial statements for the year ended 31 December 2014. These annual financial statements were prepared on a going concern basis in accordance with the Companies Act 2006 applicable to companies reporting under International Financial Reporting Standards and in accordance with applicable UK law, applicable Australian law as amended by the Australian Securities and Investments Commission Order dated 9 January 2015 and Article 4 of the European Union IAS regulation and with:

- International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB) and interpretations issued from time to time by the IFRS Interpretations Committee (IFRIC) both as adopted by the European Union and which were mandatory for EU reporting as at 31 December 2014;

- IFRIC 21 "Levies" which had been adopted by the EU and is mandatory as at 31 December 2015 for EU reporting and is available for early adoption; and

- International Financial Reporting Standards as issued by the IASB and interpretations issued from time to time by the IFRIC which were mandatory as at 31 December 2014.

The condensed financial statements are unaudited and do not constitute statutory accounts as defined in Section 434 of the United Kingdom Companies Act 2006. The financial information for the year to 31 December 2014 included in this report has been extracted from the full financial statements filed with the Registrar of Companies and does not constitute statutory accounts as defined in section 434 of the Companies Act 2006. The Auditors' report on these full financial statements was unqualified, did not include a reference to any matters to which the auditor drew attention by way of emphasis of matter and did not contain statements under section 498 (2) (regarding adequacy of accounting records and returns), or under section 498 (3) (regarding provision of necessary information and explanations) of the Companies Act 2006.

Accounting policies

The condensed consolidated interim financial statements have been drawn up on the basis of accounting policies, methods of computation and presentation consistent with those applied in the financial statements for the year ended 31 December 2014 except for the adoption of a number of amendments issued by the International Accounting Standards Board ('IASB') and endorsed by the EU which apply for the first time in 2015. This basis of accounting is referred to as 'IFRS' in this report. The new pronouncements do not have a significant impact on the accounting policies, methods of computation or presentation applied by the Group and therefore the prior period consolidated financial statements have not been restated. The Group has not early adopted any amendments, standards or interpretations that have been issued but are not yet effective.

The critical accounting judgements and key sources of estimation uncertainty for the half year are the same as those disclosed in the Group's consolidated financial statements for the year ended 31 December 2014.

The financial information by business unit and the geographic analysis of sales by destination provided on pages 10 to 12 and 41 of this press release respectively, satisfy the disclosure requirements of IFRS 8 'Operating Segments' for interim financial statements and also provide additional voluntary disclosure which the Group considers is useful to the users of the financial statements.

Going concern

After making enquiries and having reassessed the principal risks, the directors considered it appropriate to adopt the going concern basis of accounting in preparing the interim financial information.

Non-GAAP measures

The Group presents certain non-GAAP financial measures, including underlying earnings, which are reconciled to directly comparable IFRS financial measures on page 57 of this report. These non-GAAP measures are used internally by management to assess the performance of the business. They are not a substitute for the IFRS measures and should be considered alongside those measures.

Directors' statement of responsibility

In the directors' opinion:

The condensed consolidated interim financial statements on pages 30 to 50 including the notes have been prepared in accordance with IAS 34 'Interim Financial Reporting' as adopted by the European Union, the Disclosure and Transparency Rules ('DTR') of the Financial Conduct Authority in the United Kingdom, applicable accounting standards and the Australian Corporations Act 2001 as modified by an order of the Australian Securities and Investments Commission issued on 15 May 2015, using the most appropriate accounting policies for Rio Tinto's business and supported by reasonable and prudent judgements.

The condensed consolidated interim financial statements give a true and fair view of the Rio Tinto Group's financial position as at 30 June 2015 and of its performance, as represented by the results of its operations, comprehensive income and expense and its cash flows for the six months then ended.

There are reasonable grounds to believe that each of the Rio Tinto Group, Rio Tinto Limited and Rio Tinto plc will be able to pay its debts as and when they become due and payable.

The interim management report includes a fair review of the information required by DTR 4.2.7 and DTR 4.2.8, namely:

- an indication of important events that have occurred during the first six months and their impact on the condensed set of consolidated financial statements, and a description of the principal risks and uncertainties for the remaining six months of the financial year; and

- material related-party transactions in the first six months and any material changes in the related-party transactions described in the last annual report.

Signed in accordance with a resolution of the Board of Directors.

Independent review report of PricewaterhouseCoopers LLP to the members of Rio Tinto plc and PricewaterhouseCoopers to the members of Rio Tinto Limited

Introduction

For the purpose of this report, the terms 'we' and 'our' denote PricewaterhouseCoopers LLP in relation to UK legal, professional and regulatory responsibilities and reporting obligations to Rio Tinto plc and PricewaterhouseCoopers in relation to Australian legal, professional and regulatory responsibilities and reporting obligations to Rio Tinto Limited.

We have been engaged by Rio Tinto plc and Rio Tinto Limited (the 'Companies') to review the interim financial information in the interim report of the Rio Tinto Group comprising the Companies and their subsidiaries, associates and joint ventures (the 'Group') for the six months ended 30 June 2015, which comprises the Group income statement, Group statement of comprehensive income, Group cash flow statement, Group balance sheet, Group statement of changes in equity and related notes (including the financial information by business unit). We have read the other information contained in the interim report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial information.

PricewaterhouseCoopers has also reviewed the directors' declaration set out on page 51 in relation to Australian regulatory requirements.

Directors' responsibilities

The interim report is the responsibility of, and has been approved by, the directors of the Companies. The directors are responsible for preparing the interim report in accordance with the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority and the Corporations Act 2001 in Australia as amended by the Australian Securities and Investments Commission Order dated 15 May 2015 (the 'ASIC Order' described in the Australian Corporations Act - Summary of ASIC relief) and for such internal control as the directors determine necessary to enable the preparation of the interim report that gives a true and fair view and is free from material misstatement, whether due to fraud or error.

As disclosed in Note 1 Principal Accounting Policies of the 2014 Annual Report, the financial statements of the Group are prepared in accordance with International Financial Reporting Standards ('IFRS') as adopted by the European Union. The interim financial information included in this interim report has been prepared in accordance with International Accounting Standard IAS 34, Interim Financial Reporting, as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

Our responsibility

Our responsibility is to express a conclusion on the interim financial information in the interim report based on our review. PricewaterhouseCoopers LLP have prepared this review report, including the conclusion, for and only for Rio Tinto plc for the purpose of the Disclosure and Transparency Rules of the Financial Conduct Authority and PricewaterhouseCoopers have prepared this review report, including the conclusion, for and only for Rio Tinto Limited for the purpose of the Corporations Act 2001 in Australia as amended by the ASIC Order and for no other purpose. We do not, in producing this report, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.

Scope of review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) ISRE 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity issued by the Auditing Practices Board for use in the United Kingdom and the Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity. As the auditor of the Group, ISRE 2410 and ASRE 2410 require that we comply with the ethical requirements relevant to the audit of the annual financial report.

A review of interim financial information 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 International Standards on Auditing (UK and Ireland) or 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.

Independence

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

Conclusion of PricewaterhouseCoopers LLP for Rio Tinto plc

Based on our review, nothing has come to our attention that causes us to believe that the interim financial information in the interim report of the Group for the six months ended 30 June 2015 is not prepared, in all material respects, in accordance with International Accounting Standard IAS 34 Interim Financial Reporting as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

Conclusion of PricewaterhouseCoopers for Rio Tinto Limited

Based on our review, which is not an audit, we have not become aware of any matter that makes us believe that the interim report of Rio Tinto Limited is not in accordance with the Corporations Act 2001 in Australia as amended by the ASIC Order, including:

a) giving a true and fair view of the Group's financial position as at 30 June 2015 and of its performance for the half-year ended on that date; and

b) complying with International Accounting Standard IAS 34 Interim Financial Reporting as adopted by the European Union and the Corporations Regulations 2001 in Australia.

Underlying earnings is reported by Rio Tinto to provide greater understanding of the underlying business performance of its operations. Underlying earnings and Net earnings both represent amounts attributable to owners of Rio Tinto. Exclusions from Underlying earnings relating to equity accounted units ('EAUs') are stated after tax and included in the column 'Pre-tax'. Items (a) to (f) below are excluded from Net earnings in arriving at Underlying earnings.

(a) Charges relating to impairment of non-current assets other than undeveloped projects.

Impairment charges of US$421 million net of tax related to the Group's aluminium and uranium businesses. As a result of the Rio Tinto Board approval not to progress the Ranger 3 Deeps work to a feasibility study, the value of the Group's subsidiary Energy Resources of Australia assets diminished. This resulted in a pre-tax write down to property, plant and equipment and intangible assets of US$260 million and the write off of deferred tax assets of US$123 million. Other impairment charges during 2015 related to challenging economic conditions at Carbone Savoie and an anticipated disposal in the Aluminium portfolio.

In 2014, the post-tax impairment charge of US$843 million represents adjustments to reduce the carrying value of assets in the Aluminium portfolio. This includes the impairment of Kitimat in British Columbia as a result of further revisions to future capital required to complete the modernisation project.

(b) The 2015 gain related mainly to the sale by Turquoise Hill Resources (TRQ) of 25.7 per cent of its holdings in SouthGobi Resources (SGR) on 23 April 2015. Rio Tinto also sold its 77.8 per cent interest in Murowa Diamonds and 50 per cent interest in Sengwa Colliery Ltd (Sengwa) to RZ Murowa Holdings Limited on 17 June 2015.

In 2014 net post-tax losses on disposal of interests in businesses of US$157 million relate mainly to indemnities provided in respect of prior disposals, and further adjustments in respect of contractual obligations for product sales and delivery which remain with the Group following sale of the Clermont mine on 29 May 2014.

(c) Valuation changes on currency and interest rate derivatives, which are ineligible for hedge accounting, other than those embedded in commercial contracts, and the currency revaluation of embedded US dollar derivatives contained in contracts held by entities whose functional currency is not the US dollar.

Reconciliation of Net earnings to Underlying earnings (continued)

(d) Valuation changes on commodity derivatives, including those embedded in commercial contracts, that are ineligible for hedge accounting, but for which there will be an offsetting change in future Group earnings.

(e) In 2014, the charge of US$116 million (after non-controlling interests and tax), calculated in accordance with IFRS 2 'Share-based Payment', reflects the discount to an estimate of fair value at which shares are transferrable to the Government of Guinea under the Investment Framework ratified on 26 May 2014.

(f) Other credits and charges that individually or in aggregate, if of a similar type, are of a nature or size to require exclusion in order to provide additional insight into business performance.
