Activities span the world and are strongly represented in Australia and North America with significant businesses in Asia, Europe, Africa and South America.

Forward-looking statements

This announcement includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts included in this announcement, including, without limitation, those regarding Rio Tinto’s financial position, business strategy, plans and objectives of management for future operations (including development plans and objectives relating to Rio Tinto’s products, production forecasts and reserve and resource positions), are forward-looking statements. These statements may generally, but not always, be identified by the use of words such as “anticipates”, “should”, “expects”, “estimates”, “believes”, “intends”, “aims”, “projects”, “will”, “targets”, “set to”, “may”, “plans” or similar expressions. In particular, among other statements, certain statements under the caption “Dividends” and elsewhere in this report with regard to expected levels of growth, profitability, capital expenditure, returns to shareholders (capital or otherwise) and dividends are all forward-looking in nature.

Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance, achievements, strategy, plans or objectives of Rio Tinto, or industry results, to be materially different from any future results, performance, achievements, strategy, plans or objectives expressed or implied by such forward-looking statements. Such forward-looking statements are based on numerous assumptions regarding Rio Tinto’s present and future business strategies and the environment in which Rio Tinto will operate in the future. Among the important factors that could cause Rio Tinto’s actual results, performance or achievements to differ materially from those in the forward-looking statements are levels of actual production during any period, levels of demand and market prices, the ability to produce and transport products profitably, the impact of foreign currency exchange rates on market prices and operating costs, operational problems, political uncertainty and economic conditions in relevant areas of the world, the actions of competitors, activities by governmental authorities such as changes in taxation or regulation and such other risk factors identified in Rio Tinto’s most recent Annual Report and Accounts in the United Kingdom and Australia and the most recent Annual Report on Form 20-F filed with the United States Securities and Exchange Commission (the “SEC”) or Form 6-Ks furnished to, or filed with, the SEC. Forward-looking statements should, therefore, be construed in light of such risk factors and undue reliance should not be placed on forward-looking statements. These forward-looking statements speak only as of the date of this announcement. Rio Tinto expressly disclaims any obligation or undertaking (except as required by applicable law, the UK Listing Rules, the Disclosure and Transparency Rules of the Financial Conduct Authority and the Listing Rules of the Australian Securities Exchange) to release publicly any updates or revisions to any forward-looking statement contained herein to reflect any change in Rio Tinto’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based.

Nothing in this announcement should be interpreted to mean that future earnings per share of Rio Tinto plc or Rio Tinto Limited will necessarily match or exceed its historical published earnings per share.

Results for the six months ended 30 June 2014

Continued performance improvement through cost reductions and production records

–

Sustainable cost reductions have already exceeded the full year 2014 target, with $3.2 billion of operating cost improvements compared with 2012. A further $1 billion of sustainable operating cash cost improvements are now anticipated by the end of 2015. The rate of cost savings is expected to slow to around $250 million in the second half of 2014, due to planned operational activities, in particular the maintenance shut at the Kennecott Utah Copper smelter. In 2015 the pace of cost savings is expected to increase again, to around $750 million in 2015 compared with 2014.

–	Exploration and evaluation costs reduced to $340 million in the first half. The Group expects full year expenditure to be maintained at less than $900 million going forward.

–	Net headcount reduction of 2,200 across the Group’s managed operations during the first half of the year. This includes 750 roles which left the Group from divested assets.

–	Strong operational performance with first half records set for iron ore production and shipments and thermal coal production. Iron ore growth predominantly consists of high quality Pilbara Blend products, the reference point for the 62 per cent index, which continue to command attractive prices.

–	Extending our competitive advantages as the Pilbara’s lowest cost producer with unit cash costs of $20.40 per tonne, excluding royalties and freight, in 2014 first half, and an average realised iron ore price of $99 per wet metric tonne.

–	Higher copper volumes driven by improved grades and concentrator recoveries at Kennecott Utah Copper and the ramp-up at Oyu Tolgoi. Sales exceeded production at Oyu Tolgoi as logistics commissioning issues were resolved, enabling a strong acceleration in shipments.

–	Gove now operating as a bauxite export business following the curtailment of the refinery in May and is expected to ramp up export capacity to 8 million tonnes per annum (Mt/a) by the end of 2015.

Strengthening our balance sheet by increasing operating cash flows and reducing capex

–

Cash flows from operations of $8.7 billion, up eight per cent compared with 2013 first half, reflecting continued cost reductions and strong volume growth. These compensated for lower prices, $0.6 billion of adverse current trade working capital movements and $0.4 billion lower dividends from Escondida.

–	Capital expenditure reduced to $3.6 billion in 2014 first half. 2014 capex is now expected to be around $9 billion, $2 billion below previous guidance, with capex in 2015 expected at around $8 billion. Beyond 2015, capex is expected to be maintained at around $8 billion a year in the medium term.

–

Net debt reduced to $16.1 billion at 30 June 2014, $1.9 billion less than on 31 December 2013 and $6.0 billion less than on 30 June 2013. First half 2014 cash inflows included $1.2 billion from holders of non-controlling interests relating to the Turquoise Hill Resources Ltd (Turquoise Hill) rights issue and $1.0 billion from completion of the Clermont mine divestment. In 2014 first half, the Group repaid $2.7 billion of borrowings.

Delivering results

–	Full ramp-up of the Pilbara iron ore expansion to 290 Mt/a achieved in May, two months ahead of schedule. This marks a major milestone in the delivery of our Pilbara growth plan.

–	The rail duplication and track work required for the 360 Mt/a expansion is now complete. Critical 360 Mt/a port infrastructure on track for anticipated completion by the end of the first half of 2015.

–	The Aluminium group achieved EBITDA of $1.1 billion, up 26 per cent on 2013 first half, despite LME aluminium prices averaging nine per cent lower.

–	Strong performance from the Copper group reflected increased volumes from Kennecott Utah Copper and ramp-up at Oyu Tolgoi, as well as enhanced productivity and improving cost position.

Rio Tinto 2014 Form 6-K 3

Significant potential for growth in free cash flows

–	Strong cash flow generation from a low-cost diversified portfolio of world-class assets, demonstrating considerable resilience to commodity price changes.

–	Industry-leading growth in the highest margin businesses: delivering eight per cent compound annual copper-equivalent growth from 2012 to 2015.

–	A strong foundation is in place for material increases in cash returns to shareholders following a reduction in net debt of $6 billion over the past year and the improved cash flow generation capability of the business.

–	The Group is committed to the progressive dividend policy, with considerable capacity to further enhance this with consistent additional cash returns to shareholders in the future.

Economic outlook

–	Overall, we remain confident of the long-term fundamentals of demand, whilst recognising the changing nature of China’s economic development.

–	Global GDP growth in 2014 is expected to exceed three per cent which will support commodity demand.

–	The Chinese Government is dealing effectively with the rebalancing of its economy, with its desired GDP growth of 7.5 per cent in 2014 on target.

–

Rio Tinto continues to forecast Chinese crude steel production reaching 1 billion tonnes towards 2030 as urbanisation rates approach 70 per cent. Chinese crude steel production currently stands at 830 Mt/a: steel demand in China is expected to grow by between three and four per cent in 2014 compared with 2013.

–

Approximately 125 million tonnes of high-cost iron ore supply is expected to exit the market in 2014, as lower-grade producers from China and less traditional supply countries curtail production. This is expected to offset the impact of new supply to seaborne markets during 2014 from Australian and Brazilian producers.

–	Recent supply increases from new copper mines has moved the copper market into surplus.

–	Chinese demand for alternative sources of bauxite is expected to increase as stocks are depleted and Indonesian material remains unavailable due to the export ban.

–	Aluminium supply curtailments and stronger demand are expected to mitigate the impact of regulatory changes on inventories. The market excluding China is currently in deficit.

Global growth

Overall, we remain confident of the long-term fundamentals of demand, whilst recognising the changing nature of China’s economic development. Volatility in global financial markets is currently low, attributable to clear monetary policy direction from central banks, but geopolitical uncertainties, notably in Ukraine, the Middle East and the South China Sea, and economic risks could give rise to short-term fluctuations in our markets.

In China, we still expect annual growth to end up near the official forecast of 7.5 per cent due to targeted expansionary policies. Endeavouring to address imbalances from its investment-led growth model, Chinese authorities are engaged in a delicate balancing act to control credit expansion while limiting loss of confidence and negative effects spreading across the national economy.

The large stimulus packages of the past have been replaced with a range of tailored measures to prevent adjustments escalating into a negative spiral. Intervention has included directives to banks, a modest depreciation of the Chinese RMB to unwind speculative currency inflows and a symbolic tolerance towards small bond defaults. This intervention has been well managed so far with improvements in export growth and, to a lesser degree, manufacturing contributing to China’s GDP growth.

These measures have contributed to a bearish short-term outlook in China’s property market. Weak sales growth, high inventories and financing difficulties are contributing to weak fundamentals. Offsetting this, in part, the Government is incentivising infrastructure investment.

In the United States, the rebound in second quarter growth, after the negative impacts from weather disruptions earlier in the year, indicates that the backbone of the recovery seems intact. Unemployment has fallen and inflationary pressures are starting to build, once again raising questions over the timing of the first rise in the Federal Reserve rate since the global financial crisis.

The Eurozone continues to flirt with deflation risks, sparking debate over quantitative easing from the European Central Bank. Growth remains unbalanced with Germany leading a stronger core while countries with high debt levels continue to lag despite bond yields being back to pre-crisis levels. While growth is returning to the Eurozone for the first time since 2011, it remains anaemic and with unresolved underlying fragilities.

Rio Tinto 2014 Form 6-K 5

Commodities

In the second half of 2014, China’s crude steel production is expected to remain at the current level of approximately 830 Mt/a, with steel demand expected to grow by between three and four per cent over the previous year. Growth in infrastructure (up around nine per cent), machinery (up around five per cent) and transport (up around 14 per cent) are expected to outweigh the weakness in residential construction activity (down around three per cent). There has also been a strong increase in Chinese finished steel exports in recent months, in particular to Japan, Korea, Taiwan and the ASEAN region with net finished steel exports approximately 40 per cent higher in 2014 first half compared with the same period of 2013. Much of the new non-Rio Tinto iron ore supply has been of lower iron ore content with higher contaminants. This has led to a more marked price differential between the 58 per cent and 62 per cent indices and greater discounting of lower-quality material by some producers. In turn, lower-grade producers from China and less-traditional supply countries have started to curtail production, with approximately 125 million tonnes of high-cost supply expected to exit the market in 2014.

New mine supply has also moved the copper market into surplus over the past year, although the effects on prices have been more muted, with additional supply absorbed by Chinese bonded warehouses. Chinese corporate bond defaults in March raised concerns over a potential hardening of regulation on copper stock financing, resulting in price volatility. While more copper supply is expected to ramp up over the coming year, the long-term fundamentals remain supported by the complexity and high cost of new projects.

Aluminium premiums, excluding China, reached record levels in 2014, in line with increased demand and a lack of physical supply. Regulatory changes that increase the speed with which stocks can exit LME warehouses may result in declining premiums, but supply curtailments and stronger demand should mitigate this impact with the market outside China now in deficit. Meanwhile, the ore export ban has stopped flows of Indonesian bauxite into China. The impact on prices has so far been limited as Chinese refineries had built significant inventory positions. These have begun to deplete, which could result in stronger demand for alternative bauxite supplies if Indonesian exports do not resume in the coming months.

2014 first half		5,116			4,402

Prices

The effect of price movements on all major commodities in 2014 first half was to decrease underlying earnings by $1,392 million compared with 2013 first half.

The average Platts price for 62 per cent iron Pilbara fines was 20 per cent lower on average compared with 2013 first half while hard coking coal benchmark prices were 22 per cent lower and thermal coal spot prices averaged 16 per cent lower. Average copper prices were down nine per cent and LME prices for gold and aluminium averaged 15 and nine per cent lower, respectively.

Rio Tinto 2014 Form 6-K 7

Exchange rates

Compared with 2013 first half, the US dollar, on average, rose by ten per cent against the Australian dollar, by seven per cent against the Canadian dollar and by 14 per cent against the South African rand. The effect of all currency movements was to increase underlying earnings relative to 2013 first half by $505 million.

Volumes

Volumes enhanced earnings by $911 million compared with 2013 first half. These were achieved primarily in iron ore, where a new annual sales volume record was achieved, due to increased capacity at the Pilbara ports and productivity improvements. Volumes also rose in copper, from the recovery at Kennecott Utah Copper, in line with higher ore grades and increased throughput.

Cash costs, exploration and evaluation

Rio Tinto made further strong progress on its cost reduction programme and has now exceeded its $3 billion target compared with the 2012 base. In 2014 first half, the Group realised $929 million pre-tax ($661 million post tax) in operating cash cost savings. This was in addition to the $2,279 million pre-tax ($1,559 million post-tax) achieved in 2013.

Exploration and evaluation spend was reduced by $187 million (on a consolidated, pre-tax basis) in the first half. Evaluation spend has been prioritised on those projects with the greatest potential to deliver value in the medium term, with spend on certain longer dated options reduced.

In 2014 first half, the Group reduced headcount by 2,200, of which 750 roles left the Group through divested assets.

Tax

The 2014 first half effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 30 per cent compared with 38 per cent in 2013 first half. The decreased charge was primarily attributable to lower Minerals Resource Rent Tax (MRRT) in line with lower iron ore prices and the absence of prior year tax provisions. The Group expects an effective tax rate in the range of 30 to 33 per cent in 2014.

Non-cash / interest / other

The Group interest charge was $17 million higher than in 2013 first half, mainly reflecting lower capitalised interest following completion of capital projects in 2013.

In 2013 first half there was a $128 million earnings impact from an iron ore royalty payable to joint venture partners following a court decision. There was no such charge in 2014 first half.

Items excluded from underlying earnings

Total impairment charges of $843 million were recognised in 2014 first half. 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 Kitimat assets were impaired by $800 million (net of tax). First production from the Kitimat Modernisation Project is expected during the first half of 2015. Other impairment charges relate to a site closure and an anticipated disposal in the aluminium portfolio.

Net losses on disposal of interests in businesses of $157 million arose mainly from 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 the sale of the Clermont mine on 29 May 2014.

Non cash exchange and derivative gains of $589 million arose primarily on US dollar debt in non-US dollar functional currency Group companies, and on intragroup balances, in addition to revaluation of certain derivatives which do not qualify for hedge accounting. The exchange gains are largely offset by currency translation losses 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.

Rio Tinto 2014 Form 6-K 8

In 2013 first half, impairment charges of $119 million mainly related to a reduction in the carrying value of the Eagle nickel-copper project following the signing of a binding sales agreement. Non cash exchange losses of $1,854 million in 2013 first half arose primarily on US dollar debt in non US dollar functional currency companies. In April 2013, the Kennecott Utah Copper mine experienced a slide along a geological fault line of its north-eastern wall. Charges of $340 million were excluded from underlying earnings in 2013 first half, primarily comprising the write-off of certain deferred stripping assets and damaged equipment.

Cash flow

Cash flows from operations, including dividends from equity accounted units, were $8.7 billion, eight per cent higher than 2013 first half, reflecting the positive impact of higher volumes and the cost reduction initiatives. The variance was lower than the earnings momentum due to $0.6 billion of adverse current trade working capital movements and $0.5 billion lower dividends from equity accounted units, mainly related to Escondida. Tax payments in 2014 first half of $2.5 billion were $0.6 billion or 31 per cent higher than in 2013 first half driven by the move to monthly tax payments in Australia.

Purchase of property, plant and equipment and intangible assets (net of proceeds of sales of property, plant and equipment) declined by $3.4 billion or 48 per cent to $3.6 billion in 2014 first half, following the completion of five major capital projects in 2013 (Pilbara iron ore infrastructure expansion to 290 Mt/a, Oyu Tolgoi copper/gold mine, AP60 aluminium smelter, Kestrel coking coal mine and Argyle underground diamonds mine). Ongoing capital projects include the second phase expansion of the Pilbara iron ore infrastructure to 360 Mt/a, due to come on-stream at the end of the first half of 2015, and the modernisation of the Kitimat aluminium smelter in British Columbia which is due to be commissioned in the first half of 2015.

Disposal of businesses of $1.0 billion in 2014 first half reflect the sale of the Group’s interests in the Clermont thermal coal mine which completed on 29 May 2014.

Dividends paid in 2014 first half of $2.0 billion reflected the 15 per cent increase in the 2013 final dividend paid in April 2014.

In January 2014, $1.2 billion from the Turquoise Hill rights offering was recognised as proceeds from issue of equity to holders of non-controlling interests.

Statement of financial position

Net debt (see page F-7) decreased from $18.1 billion at 31 December 2013 to $16.1 billion at 30 June 2014 as operating cash inflows and proceeds from divestments and the Turquoise Hill rights offering more than compensated for the outflows relating to capital expenditure and the increase in the dividend. Net debt to total capital was 22 per cent at 30 June 2014 (31 December 2013: 25 per cent) and interest cover was 12 times, unchanged from 2013 first half.

Adjusted total borrowings at 30 June 2014 were $25.7 billion. The weighted average cost of total borrowings was approximately four per cent and the weighted average maturity was around nine years. The maximum amount, within non-current borrowings, maturing in any one calendar year was $3.3 billion. At 30 June 2014, approximately three quarters of Rio Tinto’s total borrowings were at fixed interest rates.

In 2014 first half, the group repaid a net $2.7 billion of borrowings including the maturity of $2.5 billion of bonds and $0.2 billion of commercial paper.

Cash and cash equivalents at 30 June 2014 were $9.6 billion (31 December 2013: $10.2 billion).

Profit for the period

Net earnings and underlying earnings, which are the focus of the commentary in this report, refer to amounts attributable to owners of Rio Tinto. Net earnings attributable to the owners of Rio Tinto in 2014 first half totalled $4,402 million (2013 first half: $1,720 million). The Group recorded a profit in 2014 first half of $4,285 million (2013 first half: $1,685 million) of which a loss of $117 million (2013 first half: loss of $35 million) was attributable to non-controlling interests.

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

Performance

The Iron Ore group’s underlying earnings of $4,683 million in 2014 first half were ten per cent higher than 2013 first half. This uplift was attributable to record sales volumes in the Pilbara, cost savings initiatives (which enhanced earnings by $181 million or $254 million pre-tax), a weaker Australian dollar and the absence of a $128 million one-off iron ore royalty payable following a court decision in the first half of 2013. This positive momentum was achieved despite the impact of lower prices which deflated earnings by $974 million.

The 38 per cent decline in capital expenditure reflects the completion of the port and rail element of the 290 Mt/a Pilbara expansion in 2013 and near-completion of the 290 Mt/a mine expansions.

Markets

2014 first half global sales of 142 million tonnes (100 per cent basis) set a new record and were 20 per cent higher than 2013 first half, as the Group reached a 290 Mt/a run rate in the Pilbara two months ahead of schedule. Sales exceeded production due to the drawdown of stockpiled iron ore inventory built at Pilbara mine sites in previous years to facilitate a ramp-up of the expanded port and rail facilities to 290 Mt/a.

Operations

2014 first half global iron ore production of 139.5 million tonnes (Rio Tinto share 109.9 million tonnes) also set a new record. A significant proportion of the additional tonnes have gone directly into Pilbara Blends, the largest traded iron ore products by volume and the industry reference iron ores in Asian steel markets.

At Iron Ore Company of Canada (IOC), saleable production was five per cent lower than in 2013 first half due to an unusually cold winter. Sales were constrained by frozen material: as a result, pellet sales were ten per cent lower and concentrate sales were 20 per cent lower than in 2013 first half.

Rio Tinto 2014 Form 6-K 14

New projects and growth options

On 13 May 2014, Rio Tinto announced that its Pilbara iron ore system of mines, rail and ports had reached a run rate of 290 Mt/a, two months ahead of schedule.

The rail duplication and track work required for the 360 Mt/a expansion is now complete. Critical 360 Mt/a port infrastructure remains on track for completion by the end of the first half of 2015.

In November 2013, Rio Tinto set out its breakthrough pathway to optimise the growth of mine capacity towards 360 Mt/a at a target all-in capital intensity of between $120-130 per tonne (100 per cent basis or low-US$100s a tonne Rio Tinto share), significantly lower than originally planned. A series of low-cost brownfield expansions will bring on additional tonnes to feed the expanded infrastructure. From a base run rate of 290 Mt/a in May 2014, annual mine production capacity is planned to increase by more than 60 million tonnes between 2014 and 2017. The majority of the low-cost growth will be delivered in the next two years, with mine production of more than 330 million tonnes (100 per cent basis) expected from the Pilbara in 2015.

In May 2014, the full incremental capacity of the second phase of the Concentrator Expansion Project at IOC was delivered with the commissioning of the additional ball mill.

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 $373 million were 74 per cent higher than in 2013 first half, and EBITDA margins improved further. The main drivers were growing momentum from the cost reduction initiatives, a weaker Australian and Canadian dollar and a further rise in market and product premiums, with 61 per cent of the Group’s primary metal sales sold as value added product generating a superior price. This was achieved despite a nine per cent decline in LME prices over the period which lowered earnings by $265 million.

Cash cost improvements lifted earnings by $162 million ($228 million pre-tax). The savings included greater production efficiencies and lower prices of raw materials, lower functional costs and increased production from Queensland Alumina (QAL), Yarwun, AP60 and Alma which lowered the unit cash cost of production.

Rio Tinto 2014 Form 6-K 15

Markets

The 2014 first half cash LME aluminium price averaged $1,753 per tonne, a decrease of nine per cent on 2013 first half.

Market premiums for aluminium are at record levels in all regions, and are expected to remain strong in the near term. With growing demand and tight physical markets, LME inventories have begun to decline. Much of the remaining inventory continues to be tied up in financing deals due to higher forward prices and low interest rates.

Bauxite prices remain strong, underpinned by growing demand and the Indonesian bauxite ban that remains in place.

Operations

The Gove bauxite mine has been operating as an export business since the curtailment of the alumina refinery in May 2014. Bauxite production and export capacity at Gove are expected to ramp up from current capacity of 6 Mt/a to 8 Mt/a by the end of 2015, following upgrades to export infrastructure. Group bauxite production was two per cent lower than in 2013 first half as Gove adjusted production to reflect the staged curtailment of the refinery.

First half alumina production was up nine per cent, reflecting stronger production at Yarwun and QAL which had both been impacted by ex-tropical cyclone Oswald in the first half of 2013. Production at Yarwun is expected to reach full capacity during the second half of 2015 as refinery design and construction challenges are progressively addressed.

Aluminium production for 2014 first half was in line with the same period of 2013. Productivity gains across the portfolio, coupled with production from the new AP60 smelter, offset the loss of production from Shawinigan which closed in November 2013.

Further actions were taken to streamline the portfolio with the announcement on 3 July 2014 that Hydro Aluminium ASA would acquire the Aluminium group’s 50 per cent interest in the SØRAL smelter in Norway.

New projects and growth options

In February 2014, the Group announced that a review of major capital projects had identified a project overrun in relation to the Kitimat Modernisation Project. The overrun evaluation is now complete and has identified the requirement for additional capital of $1.5 billion to complete the project. This was approved by the Board in August 2014, taking the total approved capital cost of the project to $4.8 billion. First production from the Kitimat Modernisation Project is expected during the first half of 2015.

Aligned to the Aluminium group’s bauxite growth strategy, the South of Embley project, a 22.5 Mt/a, tier one investment opportunity in Cape York, Queensland, with mining costs expected to be in the first quartile, continues under evaluation. Required regulatory permits are in place and the project is in advanced stage of study.

Performance

The Copper group’s underlying earnings of $594 million were 71 per cent higher than 2013 first half. This strong performance reflected increased volumes at Kennecott Utah Copper (KUC) following the recovery from the pit wall slide in April 2013, delivery of further cash cost savings and lower exploration and evaluation spend. This momentum more than offset the impact of lower prices and a $22 million loss on disposal of the Pebble project in Alaska. Cash cost savings enhanced earnings by $206 million, or $289 million pre-tax, and were in addition to the $514 million of pre-tax savings achieved in 2013.

Cash flows from operations of $554 million were 67 per cent higher than 2013 first half due to recovery at KUC and the ramp-up of operations and sales at Oyu Tolgoi, which have more than offset the impact of divestments in 2013. The rate of customer collections at Oyu Tolgoi accelerated in 2014 first half and monthly sales exceeded production which supports inventory returning to appropriate levels by the end of 2014.

The Copper group remains focused on delivering its clear strategy with the immediate objective of improving the quality of its current earnings. During the half the focus continued in three key areas: enhancing productivity at all operations, improving cost performance and simplifying the portfolio around four tier one assets while building a pipeline of growth options to make the most of the attractive long term industry fundamentals.

Good progress has been made on simplifying the portfolio. In addition to the $1.8 billion of divestments in 2013, the Copper group announced:

•

In April 2014, a gifting of its 19.1 per cent shareholding in Northern Dynasty Minerals Ltd owner of the Pebble Project, to two local Alaskan charitable foundations.

•

In July 2014, the divestment of its interest in the Sulawesi nickel project in Indonesia.

•

In July 2014, that Turquoise Hill entered a share purchase agreement with National United Resources Holdings Limited for the sale of a 29.95 per cent interest in South Gobi Resources Ltd.

Markets

Average prices in 2014 first half were lower than 2013 first half. Copper declined nine per cent to 312 cents per pound, gold decreased 15 per cent to $1,290 per ounce and molybdenum declined two per cent to $12.10 per pound.

The total impact of price changes on the Copper group, including the effects of provisional pricing movements, resulted in a decrease in underlying earnings of $91 million compared with 2013 first half.

At 30 June 2014, the Group had an estimated 266 million pounds of copper sales that were provisionally priced at US 317 cents per pound. The final price of these sales will be determined during the second half of 2014. This compared with 254 million pounds of open shipments at 31 December 2013, provisionally priced at US 333 cents per pound.

Rio Tinto 2014 Form 6-K 17

Operations

Mined copper production increased 23 per cent on a like-for-like basis, driven by higher grades and concentrator recoveries at KUC and the ramp-up at Oyu Tolgoi.

At KUC, first half production of copper and gold contained in concentrates improved significantly on the same period in 2013. This reflected the recovery from the pit wall slide in April 2013, sustained improvements in grades at the mine, higher throughput, and improved recoveries at the concentrator following completion of the flotation expansion. Molybdenum production was 27 per cent higher compared with 2013 first half due to higher grades and throughput. Production of refined copper at KUC was brought forward in anticipation of the 65-day smelter shutdown planned to start in September, which is expected to lead to lower cathode production in the second half of 2014.

Mined copper production at Escondida decreased two per cent on the first half of 2013, driven by lower ore grades, which was partially offset by higher mill throughput.

First half production at Oyu Tolgoi was 61.5 thousand tonnes of copper and 179 thousand ounces of gold in concentrates (Rio Tinto share 20.6 thousand tonnes and 60 thousand ounces, respectively). Customer collections from the Chinese bonded warehouse accelerated, with the sale of 64.7 thousand tonnes of copper and 154 thousand ounces of gold in concentrates (100 per cent basis) recognised in the first half of 2014.

New projects and growth options

Growth opportunities in the portfolio are centred on development options at Resolution and La Granja and the second stage of development at Oyu Tolgoi. This requires the resolution of all outstanding shareholder issues, the finalisation and approval of the feasibility study by all shareholders including the Government of Mongolia, the agreement of a comprehensive funding plan including project finance and the receipt of all relevant permits before further investment will be undertaken. The outstanding shareholder issues include the satisfactory resolution of the recent tax claims and the potential breach of the Investment Agreement. Delays to the restart of the development of the underground project could have an adverse impact on the carrying value of Oyu Tolgoi and result in impairment.

On 23 June 2014, Oyu Tolgoi LLC received an audit report from the Mongolian Tax Authority claiming unpaid taxes, penalties and disallowed entitlements associated with the initial development of the Oyu Tolgoi mine. On 25 June, Turquoise Hill, a 50.8 per cent owned subsidiary of Rio Tinto, notified shareholders that a notice of dispute had been filed with the Government of Mongolia. All parties continue to work together to reach a common understanding of these issues.

Project finance commitments have been extended to 30 September 2014.

Cash flows from operations (US$ millions)		193			278			-31	%
Capital expenditure (US$ millions)		106			510			-79	%

Performance

The Energy group’s underlying loss of $19 million compared with 2013 first half loss of $52 million. A programme of aggressive cost and productivity improvements, which saw record half year thermal coal production, boosted earnings by $91 million ($128 million pre-tax) while benefits associated with weaker local currencies added a further $130 million. This was offset by significantly lower prices, which reduced earnings by $205 million, and a reduced contribution following suspension of uranium processing operations at Energy Resources of Australia (ERA). Operating cash flows were driven by lower EBITDA.

Markets

At the end of the first half of 2014 thermal coal prices had declined to the lowest level since October 2009 with downward price pressure the result of global oversupply. Despite this, demand for Rio Tinto’s products from the major markets of Japan, Korea and Taiwan remained strong.

The coking coal market has also been impacted by oversupply in 2014 first half, with prices now stable but low relative to prior years. Demand from India continues to grow in line with its increasing steel demand.

Uranium spot prices are at levels not experienced since June 2005. As existing long term contracts expire, further curtailments and closures are expected to occur. Any recovery is likely to be dampened by record inventory levels.

Operations

Hard coking coal production in Australia was ten per cent higher than the first half of 2013. This was largely driven by increased production at the Kestrel mine, where the coal handling preparation plant had been shut for upgrade works in the first half of 2013 as part of the extension project completed later that year.

Semi-soft coking coal production was 16 per cent lower than the first half of 2013. This reflects changes in the production mix to maximise higher margin thermal coal.

Australian thermal coal production increased by six per cent compared with 2013 first half due to productivity gains in the Hunter Valley and additional volumes produced from a processing plant by-product stream at Hail Creek.

First half production in Mozambique was affected by rail and port constraints, as well as stoppages and operational changes in response to security considerations in the first quarter. On 30 July 2014, Rio Tinto announced that it reached an agreement to sell the Benga coal mine and other projects in the Tete province of Mozambique, to International Coal Ventures Private Limited for $50 million.

First half uranium production declined 77 per cent on the same period of 2013 with both ERA and Rössing experiencing leach tank failures in December 2013. Processing operations were suspended at ERA and were progressively restarted from 5 June following receipt of regulatory approvals. At Rössing, processing operations were reduced in the first quarter due to the December leach tank failure and in the second quarter following a planned maintenance shutdown.

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

Performance

The Diamonds & Minerals group’s underlying earnings of $160 million were 17 per cent lower than 2013 first half. 2014 first half earnings include the impact of tax settlements in Rio Tinto Diamonds of $25 million relating largely to prior years. Excluding this, and the impact of other tax changes, earnings were nine per cent higher than 2013 first half. This reflected favourable exchange rates, higher diamond prices, lower exploration and evaluation costs, a moderate increase in titanium dioxide feedstock volumes and $43 million of cash cost improvements ($60 million pre-tax), partly offset by lower prices for zircon, titanium dioxide feedstocks, borates and metallics. In absolute terms, cash operating costs were $188 million lower than 2013 first half including a $100 million benefit from exchange rate movements. Cash flows from operations of $424 million were 27 per cent higher than 2013 first half, reflecting higher EBITDA and improved working capital management.

Markets

The market for titanium dioxide and zircon has shown signs of stabilisation as industry-wide inventories have continued their return towards historical levels.

Demand for borates has been stable, with a modest increase in 2014 first half primarily due to higher demand from agriculture and from the US housing industry.

During 2014 first half, industry diamond prices moved up by eight per cent. In the medium to long run, strong demand growth is expected, especially from India and China, as disposable incomes rise, leading to higher consumer luxury demand.

Operations

Titanium dioxide feedstock production was 14 per cent lower than the first half of 2013 reflecting soft market demand. Production continues to be optimised to align with market demand and, as a result, the planned rebuild of one of nine furnaces at Rio Tinto Fer et Titane remains postponed.

Borates production was four per cent higher than in 2013 first half in response to higher sales demand and in preparation for commissioning of the new modified direct dissolving of kernite process plant in the third quarter of 2014.

Rio Tinto 2014 Form 6-K 20

First half diamond production was two per cent higher than the same period of 2013 with a strong operational performance at Diavik offsetting marginally lower carats at Argyle, reflecting the move from open pit to underground mining and the processing of lower grade tailings in the first quarter of 2014 as underground production ramped up.

New projects and growth options

The feasibility study for the Zulti South extension at Richards Bay Minerals in South Africa is expected to be completed towards the end of 2014. If approved, commissioning is scheduled for 2017 with an anticipated capital cost of around $400 million.

The Argyle underground mine remains on track to reach full capacity in 2015, with the second crusher commissioned in July 2014. This is designed to extend the mine life of Argyle until at least 2020.

The feasibility study to develop the A21 kimberlite pipe at Diavik Diamond Mine is expected to be complete in 2014. If approved, production will commence in the fourth quarter of 2018.

On 26 May 2014, Rio Tinto and its partners, Chinalco and the International Finance Corporation, signed the Investment Framework with the Government of Guinea for blocks 3 and 4 of the Simandou iron ore project. This provides the legal and commercial foundation for the project. The Investment Framework was ratified by the Guinean National Assembly in June 2014, followed by Supreme Court review and the Presidential promulgation. The project partners are continuing to work towards the completion of a feasibility study and the establishment of a funding consortium to build the infrastructure. These two elements will provide the basis for disciplined capital allocation decisions.

DIRECTORS’ REPORT

for the half year ended 30 June 2014

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 2014 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 13 January 2014, Rio Tinto acquired 510,983,220 common shares of Turquoise Hill under Turquoise Hill’s rights offering at a total cost of C$1,292,787,546.60 or C$2.53 per share. The purchase represented approximately 50.8 per cent of the common shares offered under the rights offering. The rights offering was fully subscribed. Turquoise Hill used a portion of the funds it received under the rights offering to repay all amounts outstanding under the US$1.8 billion interim funding facility and the US$600 million secured bridge funding facility each provided to Turquoise Hill by Rio Tinto.

On 28 January 2014, Rio Tinto Mining and Exploration Limited (RTMEL) received 44,126,780 common shares of Minera IRL Limited (IRL), representing approximately 19.44 per cent of the issued and outstanding common shares of IRL. The shares formed part of the consideration agreed to in the 2006 option agreement on the Ollachea Gold Project between RTMEL and IRL. The consideration for each share was C$0.1790. The shares were issued from IRL’s treasury and were not purchased by RTMEL via a market transaction. RTMEL may increase or decrease the investment in shares depending on its evaluation of the business, prospects and financial condition of IRL, the market for IRL’s securities, general economic and tax conditions and other factors. Additionally, should RTMEL not sell any of the shares for a period of one year, RTMEL shall be entitled to a cash incentive payment.

On 12 February 2014, Rio Tinto entered into an option agreement with LNG Canada, a joint venture comprising Shell Canada Energy, Phoenix Energy Holdings Limited (an affiliate of Petro-China Investment (Hong Kong) Limited), Kogas Canada LNG Ltd. (an affiliate of Korea Gas Corporation) and Diamond LNG Canada Ltd. (an affiliate of Mitsubishi Corporation) to acquire or lease a wharf and associated land at its port facility at Kitimat, British Columbia, Canada. LNG Canada is proposing to construct and operate a natural gas liquefaction plant and marine terminal export facility at Kitimat. The agreement provides LNG Canada with a staged series of options payable against project milestones. The financial arrangements are commercially confidential.

On 7 April 2014, Rio Tinto announced its intention to gift its 19.1 per cent shareholding in Northern Dynasty Minerals Ltd (Northern Dynasty), owner of the Pebble Project, to two local Alaskan charitable foundations. The decision followed the strategic review announced last year of Rio Tinto’s interest in Northern Dynasty which concluded the Pebble Project did not fit with Rio Tinto’s strategy. The shares in Northern Dynasty were divided equally between the Alaska Community Foundation to fund educational and vocational training and the Bristol Bay Native Corporation Education Foundation, which supports educational and cultural programmes in the region.

On 30 April 2014, Rio Tinto filed a complaint in the United States District Court for the Southern District of New York against the following defendants: Vale, S.A., Beny Steinmetz, BSG Resources Limited, BSG Resources (Guinea) Ltd. aka BSG Resources Guinée Ltd, BSGR Guinea Ltd. BVI, BSG Resources Guinée SARL aka BSG Resources (Guinea) SARL aka VBG-Vale BSGR Guinea, Frederic Cilins, Michael Noy, Avraham Lev Ran, Mamadie Touré, and Mahmoud Thiam. The Complaint relates to the loss of half of Rio Tinto’s mining concession in the Simandou region of south-east Guinea in 2008. Rio Tinto is asking the Court to award compensatory, consequential, exemplary and punitive damages to Rio Tinto in an amount to be determined at trial.

On 13 May 2014, Rio Tinto announced that its Pilbara iron ore system of mines, rail and ports had reached a run rate of 290 million tonnes a year (Mt/a), two months ahead of schedule.

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 (e) 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$843 million net of tax relate 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 value of the Kitimat assets diminished. Other impairment charges relate to site closure and an anticipated disposal in the Aluminium portfolio.

In 2013, the post-tax impairment charge of US$119 million represented adjustments to reduce the carrying value of the Eagle nickel-copper project to fair value less cost of disposal (‘FVLCD’) after the signing of a binding sales agreement, and the impact of commodity prices on certain short-lived copper-gold assets.

(b)

Net post-tax losses on disposal of interests in businesses of US$157 million arise mainly from 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.

Gains on disposal of interests in businesses in 2013 mainly relate to the Group’s disposal of part of its remaining interest in Constellium (formerly Alcan Engineered Products).

(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.

(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)	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.

Other exclusions include, in addition to corporate project expenditure and restructuring costs, a charge of US$230 million before non-controlling interests, calculated in accordance with IFRS 2 ‘Share-based Payment’, which 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. Refer to other disclosures on page F-12.

Other exclusions in 2013 included the estimate at 30 June 2013 of charges relating to a pit-wall slide at Kennecott Utah Copper, in addition to the adjustments relating to inventory sold by Richards Bay Minerals (‘RBM’) during the period which had been revalued on initial consolidation in 2012, and corporate project expenditure incurred in order to achieve cost and headcount reductions.

(a)

The pre-tax impairment charge of US$1,142 million relates 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.

The recoverable amount for the Kitimat cash-generating unit is US$2,184 million. This recoverable amount is classified as level 3 under the fair value hierarchy. In arriving at FVLCD, post-tax cash flows expressed in real terms have been estimated over the useful economic life of the modernised smelter, which is the principal asset of the cash-generating unit, and discounted using a post-tax discount rate of 7.3 per cent (2013: 7.3 per cent).

Other impairment charges during 2014 relate to site closure and an anticipated disposal in the Aluminium portfolio.

In 2013, the pre-tax impairment charge of US$242 million represents adjustments to reduce the carrying value of the Eagle nickel-copper project to FVLCD after the signing of a binding sales agreement on 12 June 2013, and the impact of commodity prices on certain short-lived copper-gold assets.

(b)	Pre-tax losses of US$362 million arise mainly from further adjustments in respect of contractual obligations for product sales and delivery which remain 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.

Net gains on disposal of interests in businesses in 2013 mainly related to the Group’s disposal of part of its remaining interest in Constellium (formerly Alcan Engineered Products).

(c)	Finance costs in the income statement include hedging adjustments and are net of amounts capitalised of US$263 million (30 June 2013: US$393 million).

(d)

For the purposes of calculating basic earnings per share, the weighted average number of Rio Tinto plc and Rio Tinto Limited shares outstanding during the period was 1,848.2 million (30 June 2013: 1,847.3 million), being the average number of Rio Tinto plc shares outstanding of 1,412.9 million (30 June 2013: 1,411.5 million), plus the average number of Rio Tinto Limited shares outstanding of 435.3 million (30 June 2013: 435.8 million). The profit figures used in the calculation of basic and diluted earnings per share are based on profits attributable to owners of Rio Tinto.

For the purposes 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.

1 Basis of preparation

The condensed consolidated interim financial statements included in this 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 22 December 2010 (as amended on 17 February 2012).

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 2013. These annual financial statements were prepared in accordance with International Financial Reporting Standards (‘IFRS’) and interpretations issued from time to time by the IFRS Interpretations Committee and adopted by the EU that were mandatory for calendar year 2013 or, in certain cases permitted to be early adopted.

Accounting policies

The IFRS 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 2013 except that the Group has early adopted IFRIC 21 ‘Levies’ which has been endorsed by the EU and a number of amendments issued by the International Accounting Standards Board (‘IASB’) which apply for the first time in 2014. These 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 other 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 2013.

In the interim financial statements for the six months ended 30 June 2013, a balance of US$1,080 million was included in Trade and other receivables which should have been offset against an amount of US$1,080 million included in Trade and other payables to comply with the group’s accounting policies.

The financial information by business unit and the geographic analysis of sales by destination provided on pages 11 to 13 and F-7 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.

(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 on lent by the EAU to a consolidated Group subsidiary.

(b)	Total borrowings are combined with other current financial liabilities of US$12 million (31 December 2013: US$10 million) and non-current financial liabilities of US$67 million (31 December 2013: US$81 million) in the statement of financial position.

5 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 2014 and 31 December 2013 are shown in the following table. The fair values of the Group’s cash and cash equivalents 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.

Rio Tinto 2014 Form 6-K F-9

(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, contingent consideration receivable from divested businesses, 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. Not included within the balance above are provisionally priced trade payables of US$11 million, wherein the fair value of the expected final price has fallen below the initial consideration received.

(f)

Level 3 derivatives consist of derivatives embedded in electricity purchase contracts linked to the LME with terms expiring between 2014 and 2040. The embedded derivatives are measured using discounted cash flows and option model valuation techniques. Long-term embedded derivatives with a fair value of US$299 million at 30 June 2014 are valued using significant unobservable inputs as the term of the derivative extends beyond the forward curve for aluminium.

Aluminium prices are flatlined 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 between US$2,356 per metric tonne in 2024 to US$3,156 in 2040.

The other contracts with a fair value of US$30 million at 30 June 2014 are categorised as level 3 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 during the six months to 30 June 2014 or the year ended 31 December 2013.

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 2014 (year ended 31 December 2013).

Gains (unrealised) included in:
– Consolidated sales revenue		—			2
– Net operating costs		106			127

Additions		4			—

Closing balance		565			461

Total (losses)/gains included in the income statement for assets and liabilities		(10	)		130

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 relates to long term pricing wherein internal pricing assumptions are used after the ten year LME curve. A ten per cent increase in long term metal pricing assumptions would result in a US$124 million (31 December 2013: US$165 million) decrease in carrying value. A ten per cent decrease in long term metal pricing assumptions would result in a US$69 million (31 December 2013: US$94 million) increase in carrying value.

6 Acquisitions and disposals

Simandou Investment Framework

On 26 May 2014, Rio Tinto and its Simandou project partners signed an Investment Framework with the Government of Guinea and agreed to transfer an equity interest in Simfer S.A., to the state. The arrangement allows the Government of Guinea to acquire equity interests of up to 25 per cent of Simfer S.A. at a discount to fair value and a further ten per cent at full fair value. Arrangements to transfer an interest in a subsidiary undertaking at a discount to fair value are considered to be a share-based payment. The discount provided or value given on the 25 per cent interest in Simfer S.A. has been calculated in accordance with IFRS 2 ‘Share-based payment’ as a charge of US$230 million.

The first tranche of shares comprising 7.5 per cent Non-Contributory Shares was transferred free of charge to the Government of Guinea on 26 May 2014. A second tranche comprising ten per cent Ordinary Contributory Shares may be acquired at any time for a pro rata share of historical mining cost. The third tranche of shares comprising 7.5 per cent Non-Contributory Shares may be transferred at any time after 22 April 2016 free of charge. The remaining two tranches of five per cent Ordinary Contributing Shares may be acquired by the Government of Guinea at market value at any time after 22 April 2026 and 22 April 2031 respectively.

Oyu Tolgoi cash generating unit

An impairment review of the Oyu Tolgoi cash-generating unit at 31 December 2013 resulted in a pre-tax impairment of US$1,149 million to goodwill and US$3,567 million to property, plant and equipment, primarily as a result of the delay in developing the underground mine. No goodwill remains in the Group’s statement of financial position following the 2013 impairment, however in accordance with IAS 36 ‘Impairment of Assets’, the Group is required at each reporting date to assess whether there are any indicators that an asset may be impaired.

A consideration of external and internal sources of information impacting the valuation of the Oyu Tolgoi cash-generating unit at 30 June 2014 did not indicate that Oyu Tolgoi was impaired.

The restart of the underground development is dependent upon approval by the shareholders of Oyu Tolgoi LLC of the feasibility study. Rio Tinto continues to engage with the Government of Mongolia with the aim of resolving a number of outstanding shareholder issues which have delayed the distribution of the feasibility study. Lender commitments for project financing are currently scheduled to expire on 30 September 2014. Delays to the relative timing of cash flows for restart of the development of the underground could have an adverse impact on the recoverable amount of the Oyu Tolgoi cash-generating unit and result in impairment.

Capital commitments

Capital commitments, excluding the Group’s share of joint venture capital commitments, were US$4,411 million (31 December 2013: US$5,499 million).

The Group’s share of joint venture capital commitments contracted for at 30 June 2014 but not yet incurred were US$1,302 million (31 December 2013: US$1,747 million).

Contingent liabilities (subsidiaries and joint operations)

Contingent liabilities, indemnities and other performance guarantees were US$354 million at 30 June 2014 (31 December 2013: US$489 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 statement of financial position, where the likelihood of the guarantees or indemnities being called is assessed as possible rather than probable or remote. There were no 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.

GContingent assets

The Group has various insurance claims outstanding with reinsurers including claims relating to the Manefay slide at Kennecott Utah Copper in April 2013. An interim progress payment was received on this claim in 2013 and engagement with insurers continues.

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 2013 Annual report.
