The financial results are prepared in accordance with IFRS and are unaudited. (1) Underlying 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 attributable to the owners of Rio Tinto. Net earnings and underlying earnings relate to profit attributable to owners of Rio Tinto. Underlying earnings is defined and reconciled to net earnings on page 12. EBITDA is defined on page 11. Underlying EBITDA excludes the same items that are excluded from underlying earnings and is reconciled to the Income Statement in the Financial Information by Business Unit on page 9.

Chairman's comments

Chairman Jan du Plessis said "Lower prices were the main driver of a reduction in underlying earnings in the first half of 2012, but overall we continue to generate strong earnings and cash flows. This demonstrates the strength and resilience of our high quality assets and reaffirms the benefits of our consistent, clear and disciplined strategy of investing in and operating large, long-term, cost-competitive mines and businesses.

"Whilst we are mindful of short-term uncertainties we remain convinced of the strength of the long-term demand outlook. We have taken a considered approach to investment, committing capital only to projects that will deliver value for shareholders under any probable macroeconomic conditions.

"Our interim dividend increased by 34 per cent, in line with our policy and the increase announced six months ago. All capital allocation decisions take into account our aim of maintaining a strong balance sheet and a single A credit rating. We are mindful of balancing the high returns that can be achieved from investing in our superior growth pipeline with the desire for cash returns to shareholders, including our progressive dividend policy."

Chief executive's comments

Chief executive Tom Albanese said "We continue to generate strong margins despite falling prices, reflecting the low cost nature of our businesses and our first-rate operational performance. We are reaping the benefits of investing early in iron ore, which is producing consistently high returns.

"We have been signalling for some time that markets would remain volatile and we have seen challenging conditions in the first half. Although sentiment remains negative in Europe and the US recovery is still fragile, our order books are full and we expect Chinese GDP growth to be around eight per cent in 2012. We expect to see signs of improvements in Chinese economic activity by the end of the year, with growth picking up more strongly as Government stimulus measures announced in the second quarter begin to flow through to infrastructure investment. Around 500 of these investment projects are slated to start later this year and in 2013.

"We have some of the best quality growth projects in the world and the flexibility to phase investment plans. Many of our projects are close to completion and will start generating revenues in the near term. Benga has already made its first coking coal shipment, the Yarwun 2 alumina refinery is complete and ramping up, Oyu Tolgoi starts commercial production next year and we will increase Pilbara iron ore production capacity by more than 50 million tonnes a year by the end of 2013.

"Our Pilbara operations enjoy one of the highest margins in the industry, low relative capital intensity of investment and we have one of the strongest track records in the mining industry of completing projects on time and budget.

"Across the sector, miners are facing increasing costs and we are actively undertaking measures to tackle this challenge. Rio Tinto has a long-established track record of cost control and productivity improvement. While cost increases have abated somewhat, this remains a major area of focus as we continually seek to enhance our operational and financial performance. We are placing a high priority on productivity improvements at our operations, where around 90 per cent of our costs are incurred, and are implementing a programme to improve the efficiency and effectiveness of our support and service functions across the business.

"We have the added advantage of clear leadership in innovation, where we continue to make real progress in implementing step-change technologies. From autonomous trucks and trains to faster underground tunnelling and advanced mineral recovery, all of these initiatives are aimed at reducing costs and improving productivity.

"With our confidence in the long-term outlook, superior assets and high quality growth pipeline, we remain well positioned to deliver shareholder value over the long term."

Prices

The effect of price movements on all major commodities in 2012 first half was to decrease underlying earnings by $1,936 million compared with 2011 first half. Prices declined for nearly all of Rio Tinto's major commodities, with the exception of gold which was up 14 per cent on 2011 first half, minerals (mainly borates and titanium dioxide feedstocks) and thermal coal.

Average thermal coal prices were higher in the 2012 first half compared with 2011 first half, although the 2012/13 Japanese fiscal year contract price, applicable from April 2012, is lower than the previous contract price. Copper prices were down 14 per cent, aluminium prices averaged 15 per cent lower and molybdenum was 17 per cent lower. The average Platts price for 62 per cent Pilbara fines declined by 21 per cent compared with 2011 first half.

Exchange rates

Compared with 2011 first half, on average, the US dollar was unchanged against the Australian dollar but strengthened by three per cent against the Canadian dollar, by seven per cent against the Euro and by 15 per cent against the South African Rand. The effect of all currency movements was to increase underlying earnings relative to 2011 first half by $200 million.

Volumes

Volume increases enhanced earnings by $366 million compared with 2011 first half. These were achieved primarily in iron ore, where sales volumes rose four per cent due to increased capacity at the Pilbara ports, and at Rio Tinto Coal Australia, in line with recently completed thermal coal expansions. Production of iron ore and coal benefited from a reduced impact from severe wet weather compared with 2011 first half. Volume declines lowered earnings by $584 million compared with 2011 first half. These were driven by copper and gold, with lower grades at Kennecott Utah Copper and no metal share from Grasberg.

Energy and other cash costs

Industry-wide cost pressures continued during the first half of 2012, in particular at some of the mining hotspots where Rio Tinto has significant operations, such as the Pilbara region of Western Australia. Rio Tinto has a clear focus on cost control including support and service costs across the organisation.

Higher energy costs across the Group lowered underlying earnings by $12 million compared with 2011 first half. In 2012 first half, many operations were impacted by higher fuel, diesel and power rates.

Higher other cash costs during the first half of 2012 decreased underlying earnings by $388 million compared with 2011 first half due to a combination of fixed production cost inefficiencies associated with lower volumes due to grade, higher maintenance costs and costs associated with operational readiness for the Pilbara expansion of iron ore production.

Exploration and evaluation

In 2012 first half, evaluation work progressed at many of the Group's projects including the Resolution and La Granja copper projects and the Simandou iron ore project. In the period, Rio Tinto divested various exploration properties, including interests in Extract Resources and Kalahari Minerals, resulting in net gains on disposal of $260 million for the Group. The impact from higher exploration and evaluation expenditure net of gains realised from divestments was to lower underlying earnings by $90 million compared with 2011 first half.

Interest/tax

The effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 27.4 per cent compared with 29.6 per cent in 2011 first half. The group interest charge was $68 million lower than in 2011 first half, mainly reflecting an increase in capitalised interest.

Items excluded from underlying earnings

A deferred tax asset of $1,043 million was recognised following the introduction of the Minerals Resource Rent Tax (MRRT) on 1 July 2012. This new legislation, which applies to companies with iron ore and coal operations in Australia, allows a deduction against future MRRT liability based on the market value of past investments in these mining assets as at 1 May 2010.

Accordingly, a deferred tax asset has been recognised to reflect the deductibility for MRRT purposes of the market value of these mining assets to the extent recovery is probable.

In 2012 first half, an impairment charge of $115 million was recognised relating to the Specialty Alumina and Cable businesses based on agreed sales values.

In 2011 first half, an impairment charge of $157 million was recognised relating to the Lynemouth smelter which was subsequently closed in March 2012. Other exclusions in 2011 first half, included in operating costs, related mainly to the write-down of inventory balances at Energy Resources of Australia. Other charges excluded from underlying earnings comprise costs relating to acquisition, disposal and similar corporate projects.

Cash flow

First half cash flows from operations, including dividends from equity accounted units, were $7.8 billion, 39 per cent lower than 2011 first half, primarily as a consequence of lower prices. Corporate taxes paid in 2012 first half increased by four per cent to $3.8 billion in line with higher taxable profits recorded in the second half of 2011.

Purchase of property, plant and equipment and intangible assets accelerated in 2012 first half to $7.6 billion, an increase of $2.4 billion from 2011 first half. This included the continued expansion of the Pilbara iron ore mines and infrastructure to 283 Mt/a in Western Australia, the development of the Oyu Tolgoi copper-gold project in Mongolia, the modernisation of the Kitimat aluminium smelter in British Columbia, the extension and expansion of the Kestrel coking coal mine in Queensland and the underground development of the Argyle diamond mine in Western Australia.

In 2012 first half, the Group received $1.35 billion following completion of the agreement with Chalco to develop and operate Simandou.

The Group completed its $7 billion share buy-back programme, of which $1.5 billion was spent in 2012 first half.

Dividends paid in 2012 first half of $1.7 billion were $0.4 billion higher than 2011 first half reflecting the 34 per cent increase in the 2011 final dividend.

Statement of financial position

Net debt (defined on page 35) increased from $8.5 billion at 31 December 2011 to $13.2 billion at 30 June 2012 as strong operating cash inflows were offset by outflows relating to capital expenditure, acquisitions, the increase in the dividend and the share buy-back programme. Net debt to total capital was 17 per cent at 30 June 2012 and interest cover was 15 times. Rio Tinto aims to maintain its single A credit rating.

Adjusted total borrowings at 30 June 2012 were $20.5 billion. The weighted average maturity of adjusted total borrowings was around nine years with the maximum nominal amount maturing in any one fiscal year currently $2.7 billion. At 30 June 2012, approximately two thirds of Rio Tinto's adjusted total borrowings were at fixed interest rates. In 2012 first half, Rio Tinto issued $2.5 billion of fixed rate bonds, with maturities of 3, 5, 10 and 30 years, a weighted average coupon of just under three per cent and a weighted average maturity of around 12 years. Cash and cash equivalents at 30 June 2012 were $7.3 billion.

Profit for the period

Profit in 2012 first half was $6,092 million (2011 first half $8,078 million) of which $207 million (2011 first half $491 million) was attributable to non-controlling interests, leaving $5,885 million (2011 first half $7,587 million) of net earnings attributable to owners of Rio Tinto. Net earnings and underlying earnings, which are the focus of the commentary in this report, deal with amounts attributable to equity shareholders of Rio Tinto.

Dividends

The aim of Rio Tinto's progressive dividend policy is to increase the US dollar value of ordinary dividends over time. 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. For the purposes of the 2012 interim dividend this will be converted at exchange rates applicable on 6 August 2012.

The interim dividend is set at one half of the total dividends declared for the previous year. Therefore, an interim dividend equivalent to US 72.5 cents per share has been declared by Rio Tinto plc and Rio Tinto Limited, a 34 per cent increase compared with the 2011 interim dividend of US 54 cents per share.

Rio Tinto Limited shareholders will be paid dividends which will be 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 13 September 2012 to Rio Tinto plc and ADR shareholders on the register at the close of business on 17 August 2012 and to Rio Tinto Limited shareholders on the register at the close of business on 21 August 2012. The ex-dividend date for Rio Tinto plc, Rio Tinto Limited and Rio Tinto ADR shareholders will be 15 August 2012.

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 22 August 2012 for Rio Tinto plc shareholders and by 23 August 2012 for Rio Tinto Limited shareholders.

ADR shareholders receive dividends in US dollars, which will be converted from pounds sterling by reference to the exchange rate applicable on 6 September 2012. 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 Company Secretaries' offices and from the Rio Tinto website (www.riotinto.com). The last date for receipt of the election notice for the Dividend Reinvestment Plans is 22 August 2012 for Rio Tinto plc shareholders and 23 August 2012 for Rio Tinto Limited shareholders. Purchases under the Dividend Reinvestment Plan are made on or as soon as practicable after the dividend payment date and at the prevailing market price. There is no discount available.

Capital projects

Rio Tinto has a programme of high quality projects across a broad range of commodities. Capital expenditure for 2012 is expected to total $16 billion based on approved projects and sustaining capital.

Notes to financial information by business unit

Business units have been classified according to the Group's management structure. Generally, business units are allocated to product groups based on their primary product. The Aluminium group excludes Pacific Aluminium, Other Aluminium and the Cable division of Alcan Engineered Products which are included in 'Other Operations'.

(a) Gross sales revenue includes 100 per cent of subsidiaries' sales revenue and the Group's share of the sales revenue of equity accounted units (after adjusting for intra-subsidiary/equity accounted unit sales).

(b) EBITDA of subsidiaries and the Group's share of EBITDA relating to equity accounted units represents profit before: tax, net finance items, depreciation and amortisation. Underlying EBITDA excludes the same items that are excluded from Underlying earnings.

(c) Net earnings represent profit after tax for the period attributable to the owners of the Rio Tinto Group. Earnings of subsidiaries and equity accounted units are stated before finance items but after the amortisation of discount related to provisions. Earnings attributed to business units do not include amounts that are excluded in arriving at Underlying earnings.

(d) The Group holds 65 per cent of Robe River Iron Associates, of which 30 per cent is held through a 60 per cent owned subsidiary. The Group's net beneficial interest is, therefore, 53 per cent, net of amounts attributable to outside equity shareholders.

(e) Aluminium is now presented on an integrated operations basis splitting activities between Bauxite and Alumina, Primary Metal and Other integrated operations (which in total reflect the results of the integrated production of aluminium) and Other product group items which relate to other commercial activities. Comparative information for the 6 months ended 30 June 2011 has been adjusted accordingly.

(f) Under the terms of a joint venture agreement, Rio Tinto is entitled to 40 per cent of additional material mined as a consequence of expansions and developments of the Grasberg facilities since 1998.

(g) Includes Rio Tinto's 80 per cent interest in Coal and Allied (prior to 16 December 2011 Rio Tinto's interest was 75.7%) which is managed by Rio Tinto Coal Australia, a 100 per cent subsidiary of Rio Tinto. Coal and Allied owns a 40 per cent interest in Bengalla and an 80 per cent interest in Mount Thorley, giving the Group a beneficial interest at 30 June of 32 per cent and 64 per cent, respectively.

(h) Rio Tinto Coal Mozambique (RTCM) owns and operates a number of exploration and early development stage projects, specialising in coal opportunities in southern Africa. Its principal interests are the Benga project, a 65:35 joint venture with Tata Steel Limited, which is equity accounted, and the wholly owned Zambeze coal project. These projects are located contiguously in the Tete and Moatize provinces of Mozambique. RTCM also has several prospective exploration tenements in the region.

(i) Diamonds includes Rio Tinto's interests in Argyle (100 per cent), Diavik (60 per cent) and Murowa (77.8 per cent).

(j) Includes Rio Tinto's interests in Rio Tinto Fer et Titane (RTFT) (100 per cent), QMM (80 per cent) and RBM (attributable interest of 37 per cent). On 1 February 2012 the Group announced it would take a majority stake in RBM. Operating assets at 31 December 2011 have been adjusted for amounts reclassified from 'Other items' in respect of shareholder loans at RBM.

(k) Includes Rio Tinto's interests in Rio Tinto Borax (100 per cent). Rio Tinto completed the sale of its 100 per cent interests in its talc operations on 1 August 2011.

(l) Other operations include Rio Tinto's 100 per cent interests in Pacific Aluminium, Other Aluminium and the Cable division of Alcan Engineered Products (other than its operating assets, which are part of net assets held for sale), Rio Tinto Marine and its 39 per cent interest in Constellium (formerly Alcan Engineered Products excluding the Cable division). Rio Tinto completed the sale of its Colowyo coal mine on 1 December 2011.

(m) Following finalisation of the Simandou Joint Development Agreement, and subsequent earn-in by Chalco on 24 April 2012, Rio Tinto's current interest in the Simandou Iron Ore project reduced from 95 per cent to 50.35 per cent.

(n) Rio Tinto's interest in Oyu Tolgoi LLC is held indirectly through its investment in Turquoise Hill Resources (Turquoise Hill). The Group's remaining interests in the assets of Turquoise Hill, unrelated to Oyu Tolgoi LLC, are reported in the Copper group within 'Other'. On 24 January 2012, the Group took a majority stake in Turquoise Hill and has consolidated Turquoise Hill from 1 January 2012 (Refer to 'Acquisitions and disposals' on page 37). Rio Tinto's interest in Oyu Tolgoi LLC is held indirectly through its investment in Turquoise Hill Resources (Turquoise Hill). The Group's remaining interests in the assets of Turquoise Hill, unrelated to Oyu Tolgoi LLC, are reported

(o) Capital expenditure comprises the net cash outflow on purchases less disposals of property, plant and equipment, capitalised evaluation costs and purchases less disposals of other intangible assets. The details provided include 100 per cent of subsidiaries' capital expenditure and Rio Tinto's share of the capital expenditure of equity accounted units. Amounts relating to equity accounted units not specifically funded by Rio Tinto are deducted before arriving at total capital expenditure for the Group. In addition to purchase of property, plant & equipment and intangibles of $7.6bn as reported in the cash flow statement, capital expenditure of $7.5bn also comprises disposals of property, plant and equipment, capitalised evaluation costs and disposals of intangible assets.

(p) Operating assets of subsidiaries comprise net assets excluding post retirement assets and liabilities, net of tax, and are before deducting net debt. Operating assets are stated post deduction of non-controlling interests, which are calculated by reference to the net assets of the relevant companies (i.e. net of such companies' debt).

(q) Net assets held for sale at 30 June 2012 include Specialty Alumina and Cable divisions acquired with Alcan and RTCM's Zululand Anthracite Colliery (ZAC) which was acquired with a view to resale. Net assets held for sale at 30 June 2011 relate to the Group's talc business.

Performance

The Iron Ore group's underlying earnings of $4,753 million in 2012 first half were 20 per cent lower than 2011 first half, reflecting lower iron ore prices partly offset by higher volumes. The increase in capital expenditure reflects the expansion in the Pilbara to 283 Mt/a, the expansion of Iron Ore Company of Canada (IOC) to 23 Mt/a and ongoing early stage investment at the Simandou iron ore project in Guinea.

Markets

First half sales of 109 million tonnes (100 per cent basis) from the Pilbara set a new first half record, rising by four per cent compared with the same period in 2011. Approximately 40 per cent of sales were priced with reference to a quarterly average index set at the prior quarter's average lagged by one month. The remainder was sold either on the current quarter average, current month average or spot index. Prices are adjusted for product characteristics and iron and moisture content.

Operations

The Pilbara mines achieved record production in the first half of 2012 of 114 million tonnes (Rio Tinto share 91 million tonnes), four per cent higher than the corresponding period in 2011.

Production continued to exceed sales as the business prepared itself for the expansion to 283 Mt/a, with a measured build-up of stocks at the mine sites. Rio Tinto's Pilbara ports achieved throughput at their nameplate capacity rate of 230 million tonnes over the past 12 months.

During the first half, a significant scheduled shut-down at the Cape Lambert facilities took place, involving the removal of a 40 year-old overhead conveyor gantry and installation of a fully-commissioned new stacker. The capacity of the Pilbara system increased by a further five million tonnes to 230 Mt/a during the first quarter of 2012, following the completion of the second debottlenecking project at the Dampier port on time and on budget.

At IOC, first half production was four per cent higher than the corresponding period in 2011, owing to improved product mix, lower strip ratios and mine improvements leading to additional concentrate and pellet production.

New projects and growth

The expansions of the Pilbara to 283 Mt/a (now fully approved) by the end of 2013 and 353 Mt/a by the end of the first half of 2015 remain on track, with the following progress during the first half:

-- Dampier incremental expansion to 230 Mt/a now fully operational

-- Cape Lambert dredging for 283 Mt/a and 353 Mt/a expansions complete

-- Cape Lambert piling needed for expansion to 283 Mt/a 75 per cent complete

On 8 February 2012, Rio Tinto approved $2.2 billion (Rio Tinto 100 per cent) to extend the life of the Nammuldi iron ore mine and $700 million (100 per cent basis $1.2 billion) for Cape Lambert port and rail early works for the capacity expansion to 353 Mt/a.

On 20 February 2012, Rio Tinto announced a $478 million (100 per cent basis $518 million) investment in autonomous trains for the Pilbara rail network. The first driverless train will be launched in 2014, with the AutoHaul(TM) automated train programme scheduled for completion a year later.

On 20 June 2012, Rio Tinto announced an investment of $2.0 billion (100 per cent basis $3.5 billion) over the next four years to complete the port and rail elements of the project to expand iron ore production capacity in the Pilbara to 353 Mt/a by the end of the first half of 2015. At the same time, a further $1.7 billion (Rio Tinto share 100 per cent) of largely sustaining capital expenditure was announced to extend the life of the Yandicoogina mine to 2021 and expand its nameplate capacity from 52 Mt/a to 56 Mt/a.

Rio Tinto's integrated operations will be progressively upgraded as follows:

-- 283 Mt/a by end of 2013 - Cape Lambert 53 Mt/a increment (in implementation)

-- 353 Mt/a by end of first half of 2015 - Cape Lambert 70 Mt/a increment (port, rail and power components fully approved)

At IOC, commissioning of the first phase expansion project, lifting capacity to 22 Mt/a, continued. The phase two expansion to 23.3 Mt/a is progressing, with first production expected in late 2012.

On 25 April 2012, Rio Tinto announced the completion of the agreement with Chinalco's listed subsidiary, Chalco, to develop and operate the Simandou iron ore project in Guinea, following the completion of all Chinese regulatory approvals. As a result, a Chalco-led consortium made an earn-in payment of $1.35 billion. All on-going expenditure is now funded by cash calls made of all participants (including the International Finance Corporation). Government of Guinea participation remains subject to the exercise of its various option rights.

On 20 June 2012, Rio Tinto announced an investment of $501 million (100 per cent basis $1.0 billion) for detailed design studies, early works and long-lead items at Simandou. This is primarily for rail and port infrastructure, with first commercial production planned for mid-2015.

Rio Tinto plans staged funding approvals with its partners for a progressive ramp up of the operation which will become a long-life, low-cost operation producing one of the highest grade iron ores on the market. Timing of the ramp up is dependent on receiving necessary approvals from the Government of Guinea and on the Government of Guinea progressing and finalising its financing strategy.

2012 production guidance

In 2012, Rio Tinto expects to produce approximately 250 million tonnes (100 per cent basis) from its global operations in Australia and Canada, subject to weather constraints.

The numbers in the above table exclude the production and financial results of 13 non-core assets that have been transferred to 'Other Operations' following the Group's streamlining announcement on 17 October 2011. These assets are now managed and reported separately from Rio Tinto Alcan while the Group progresses divestment options.

Performance

Rio Tinto Alcan's underlying earnings of $24 million were 93 per cent lower than 2011 first half, mainly from significantly lower prices across the business, which decreased earnings by $406 million compared with 2011 first half. Favourable currency movements mainly from the weakening Canadian dollar against the US dollar were offset by unfavourable market movements in raw material costs, mainly coke, pitch and caustic. The recovery following abnormal flooding in 2011 in Queensland, Australia was more than offset by one-off events, mainly start-up costs at Yarwun 2 and the impact of reduced operations from the lockout at Alma and the transformer incident at Shawinigan.

Rio Tinto Alcan remains committed to deliver strong margin improvements (40 per cent) through targeting a sustainable incremental EBITDA improvement of $1 billion. This will be achieved through a reduced cost structure, disciplined portfolio management, business improvement initiatives and investment and expansion of tier one assets. A run rate of $250 million of annual EBITDA improvements have been achieved to date.

Markets

The 2012 first half cash LME aluminium price averaged $2,081 per tonne, a decrease of 15 per cent on 2011 first half. A significant portion of aluminium stocks remain locked in attractive financing deals. As a result, regional premia for physical delivery of aluminium are at record levels.

Operations

Bauxite production during the first half was nine per cent higher than 2011 first half, notably at Weipa, driven by increased internal and third party demand.

Alumina production was 12 per cent higher than the first half of 2011, due to a strong performance at all refineries, notably at Queensland Alumina, where abnormal flooding in early 2011 affected coal quality, impacting production and equipment reliability.

Aluminium production was 12 per cent lower than 2011 first half, primarily reflecting the lockout at Alma (now resolved through signing of a new labour agreement) where two thirds of the smelter's capacity had been curtailed throughout the first half of the year.

On 5 July 2012, Rio Tinto Alcan announced that Alma Works employees ratified a new collective labour agreement for the Alma smelter. This initiated the return to work process for the employees, followed by the progressive restart of the smelter's production cells.

New projects and growth

Construction of the Yarwun 2 alumina refinery expansion was completed during the first half of 2012 and first bauxite was processed on 5 July 2012. First commercial production is expected in the third quarter of 2012 and the expansion is expected to ramp up to full capacity by the third quarter of 2013.

2012 production guidance

In 2012, Rio Tinto Alcan's share of bauxite, alumina and aluminium production is expected to be 30.5 million tonnes, 7.0 million tonnes and 2.3 million tonnes, respectively. These numbers exclude the 13 assets that have been identified for divestment or closure.

Performance

The Copper group's underlying earnings of $556 million were 55 per cent lower than 2011 first half. This reflected the impact of lower prices and lower volumes from a temporary reduction in copper and gold grades at Kennecott Utah Copper and no metal share from Grasberg, lower prices and an increase in evaluation expenditure.

Markets

Prices in 2012 first half were generally lower than 2011 first half. Copper declined 14 per cent to 367 cents per pound, gold increased 14 per cent to $1,652 per ounce and molybdenum declined 17 per cent to $14.8 per pound.

The total impact of price changes on the Copper product group, including the effects of provisional pricing movements, was to decrease underlying earnings by $279 million compared with 2011 first half.

At 30 June 2012, the Group had an estimated 235 million pounds of copper sales that were provisionally priced at US 348 cents per pound. The final price of these sales will be determined during the second half of 2012. This compared with 181 million pounds of open shipments at 31 December 2011, provisionally priced at US 344 cents per pound.

Operations

As previously guided, production of copper and gold in concentrates at Kennecott Utah Copper was lower during the first half of 2012 as mining progressed through lower grade areas of the open pit. A number of activities were scheduled to coincide with the period of lower ore grades and were successfully completed during the first half, including relocation of the in-pit conveyor at the mine and a 26 day maintenance shutdown at the smelter. Higher copper ore grades are expected to return during the second half of 2012.

At Escondida, mine production of copper increased 29 per cent compared with 2011 first half, due to higher copper grades and an increase in ore delivered to the concentrator attributable to improved material handling.

Based on the latest available Freeport estimates, 2012 production from Grasberg is not expected to reach the amount set in the metal sharing agreement because of planned mine sequencing in areas with lower metal grades. Accordingly, Rio Tinto's share of joint venture production is expected to be zero for the year 2012.

New projects and growth

On 14 February 2012, Rio Tinto announced that it had approved $1.4 billion (Rio Tinto share) for two projects to support higher production at Escondida. Rio Tinto's investment is expected to be funded through the company's share of Escondida's operating cash flows.

On 19 June 2012, Rio Tinto approved an investment of $660 million to extend the life of the Kennecott Utah Copper mine from 2018 to 2029. The investment includes the construction of mine infrastructure and new equipment to support pushing back the south wall of the mine.

On 24 January 2012, Rio Tinto increased its stake in Turquoise Hill to 51 per cent. Turquoise Hill owns 66 per cent of Oyu Tolgoi.

On 18 April 2012 Rio Tinto and Turquoise Hill signed an agreement under which Rio Tinto agreed to support and provide certain elements of a comprehensive funding package for Turquoise Hill that will underpin the development of the Oyu Tolgoi project. As part of the package, Rio Tinto replaced a number of the directors on the Turquoise Hill Board with Rio Tinto-nominated directors and also nominated a new management team, including the CEO and CFO.

Construction of the Oyu Tolgoi copper gold project was 90 per cent complete at the end of June. Mining and stockpiling of first ore began in April 2012, and the project remains on track to begin initial production in the second half of 2012 with commercial production of copper concentrate expected in the first half of 2013. The Phase 2 feasibility study is expected to be completed in the second half of 2012.

Ongoing progress has been made towards ensuring that electrical power from China will be available for the start of initial production at Oyu Tolgoi. Physical construction of all transmission infrastructure is complete and has been tested on both sides of the border.

On 20 July 2012, Turquoise Hill announced that the rights offering had completed, with 100 per cent of available shares subscribed, generating $1.8 billion in gross proceeds. Rio Tinto exercised all of its respective rights issued to it in the rights offering to maintain its 51 per cent interest.

2012 production guidance

In 2012, Rio Tinto share of mined and refined copper production is expected to be approximately 580,000 tonnes and 300,000 tonnes, respectively.

(1) EBITDA and underlying earnings in first half 2012 included $353 million and $249 million gain from the sale of interests in exploration properties.

Performance

The Energy group's underlying earnings of $307 million were 18 per cent lower than 2011 first half. This was primarily due to cost inflation and lower prices for coking coal and uranium, which were partially offset by higher volumes and the sale of the Group's interests in exploration properties, including Extract Resources and Kalahari Minerals, which delivered a $249 million pre and post-tax gain.

Markets

Metallurgical coal supply from Australia normalised early in the year after flood impacts in 2011, however Australian supply disruptions for premium hard coking coal in the second quarter provided some short term support. Thermal coal demand in the traditional markets of Japan, Korea and Taiwan remains strong. Longer term we expect demand to improve, with Asian demand for both thermal and metallurgical coal continuing to grow, particularly in India and China, along with both countries' preparedness to accept more imported coals in conjunction with domestic coal.

Post Fukushima, there has been little activity in uranium markets with prices showing a floor of around $50 a pound. In the medium term prices are expected to rebound as Japanese reactors gradually start up, and as new reactors continue to be built and are brought on line in China.

Operations

Production of hard coking coal and semi-soft coking coal were 9 per cent and 17 per cent above impacted first half of 2011. Wet weather events in the first half of 2012 have again impacted production although to a lesser extent than was experienced in the first half of 2011.

Australian thermal coal production was two per cent higher than the 2011 first half. The combination of increased production at Clermont and the increase in ownership of Coal & Allied more than offset the negative impacts of wet weather events in Queensland and the knock-on effect of reduced explosives supplies experienced during the fourth quarter of 2011. After three decades of operation, Rio Tinto is currently planning its final production from the Blair Athol Mine which is expected before December 2012.

Uranium production was 54 per cent higher than 2011 first half. This was driven by the resumption of normal operations at the Ranger mine following extreme wet weather in 2011, together with improved crushing performance and slightly higher mill head grade at Rossing.

New projects and growth

On 25 June 2012, Rio Tinto announced that it had exported its first shipment of premium hard coking coal from its Benga Mine in the Moatize Basin in Mozambique. During the first half, Rio Tinto Coal Mozambique produced 123,000 tonnes of thermal coal (80,000 tonnes attributable) and 130,000 tonnes of hard coking coal (85,000 tonnes attributable) at Benga. As the mine is in the commissioning phase, costs net of revenues have been capitalised. Benga is expected to move to commercial production during the third quarter of 2012.

In the Bowen Basin in Queensland, Australia, drilling programmes to support Order of Magnitude studies near Hail Creek are nearing completion.

A review of the Mount Pleasant project in New South Wales, Australia, to identify ways to reduce costs is expected to run into 2013, after which an investment decision would be made.

At Rossing, in Namibia, preparations have been made for a third phase of drilling at the Z20 project.

2012 production guidance

In 2012, Rio Tinto's share of Australian hard coking, semi soft coking and thermal coal production is expected to be 8.5 million tonnes, 3.5 million tonnes and 19.5 million tonnes, respectively. Rio Tinto's share of uranium production in 2012 is expected to be 9.6 million pounds.

Performance

The Diamonds & Minerals group's underlying earnings of $203 million were 107 per cent higher than 2011 first half. The group benefited from higher prices across the industrial minerals business and increased diamonds production. Strong earnings were partially offset by higher study costs related to expanding titanium dioxide mining and refining capacity, and divestment of the talc business in mid-2011.

Markets

Demand for refined borates softened in the first half of 2012 due primarily to economic slowdown in Europe and Asia. Titanium dioxide markets softened in the first half of 2012 as a result of pigment inventory build-up and weaker economic growth. China now represents 30 per cent of global titanium dioxide feedstock demand.

Prices and demand outlook remain strong for industrial minerals in the medium and long term, driven primarily by urbanisation in emerging economies.

Demand for rough diamonds saw a modest slowdown in the first half of 2012 across established and emerging markets. The long term outlook for diamonds remains robust; short term fluctuations will continue in line with economy cycles and global conditions.

Operations

Titanium dioxide feedstocks production was nine per cent higher than the first half of 2011, when a furnace shutdown in Canada constrained production. The increase also reflected growth in ilmenite production at QIT Madagascar Minerals, following the implementation of dry mining and other improvement initiatives.

Borates production was four per cent lower than the first half of 2011, in response to market conditions.

Diamond production at Argyle was 24 per cent higher than the first half of 2011, due primarily to the impact of heavy rains and flooding in March 2011. Construction of the underground mine at Argyle is proceeding and production is scheduled to commence in the first half of 2013. Diavik production was eight per cent higher than 2011 first half, due to higher open pit volumes and improved grades.

On 27 March 2012, Rio Tinto announced a strategic review of its diamond business that will include exploring a range of options for potential divestment of its diamonds interests.

New projects and growth

On 1 February 2012, Rio Tinto announced that it will increase its stake in Richards Bay Minerals to 74 per cent through the acquisition of BHP Billiton's 37 per cent interest. The final consideration for the acquisition will be determined through a previously agreed valuation process. Completion is subject to regulatory approvals.

2012 production guidance

In 2012, Rio Tinto's share of production is expected to be as follows:

-- Borates - 0.5 million tonnes boric oxide equivalent.

-- Titanium dioxide feedstocks - 1.6 million tonnes

-- Diamonds - 14.6 million carats

Other operations

Rio Tinto's other operations incurred a first half loss after tax of $228 million compared with earnings of $91 million in 2011 first half. This primarily related to the 13 non-core aluminium assets which were transferred out of the Aluminium group following the 17 October 2011 streamlining announcement. These assets are now managed and reported separately from Rio Tinto Alcan while the Group progresses divestment options.

On 28 March 2012, Rio Tinto announced that it had received a binding offer for its specialty aluminas business from H.I.G. The terms of the binding offer are confidential. The transaction completed on 1 August 2012.

On 21 May 2012, Rio Tinto announced that it had reached an agreement to sell Alcan Cable to General Cable Corporation for $185 million. The sale is expected to close later this year after the transaction receives all necessary regulatory clearances.

Central exploration expenditure in 2012 (post divestments and post-tax) resulted in a charge to underlying earnings of $79 million compared with a credit of $21 million in 2011 first half, as the result of an increased spend on greenfield exploration. During 2012 first half, the Group realised $11 million (post tax) from the divestment of central exploration properties compared with $85 million in 2011 first half.

The Hathor acquisition was completed in the first half of 2012. A drilling programme is underway at Roughrider and has confirmed that extensions to known uranium resources are present. Exploration for additional mineralised bodies is also being planned.

Drilling programmes to define potential resources at two projects in the region around the Amargosa bauxite resource in Brazil are continuing to intercept encouraging bauxite intervals.

Further assays received to date have confirmed encouraging potash grade and thickness from the drilling completed last quarter on the Saskatchewan potash project (Canada), a joint venture with North Atlantic Potash Inc., a subsidiary of JSC Acron. Access agreements were secured ahead of a 3D-seismic survey to aid resource definition planned for the second half of 2012.

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 2012

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 2012 and likely future developments are given on pages 1 to 20. Important events that have occurred during the period and up until the date of this report are set out below. Further information in connection with acquisitions and disposals and the impact of these on the financial statements are set out on pages 37 to 39.

Principal risks and uncertainties

The principal risks and uncertainties that could materially affect Rio Tinto's results and operations are set out on pages 10 to 12 of the 2011 Annual report and are summarised in 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.

(ii) Strategic risks

The Group may be unable to maintain the planned rate of growth due to possible constraints on the rate of capital expenditure.

The Group's exploration and development of new projects might be unsuccessful, expenditures may not be fully recovered and depleted ore reserves may not be replaced.

Rio Tinto may fail to make or successfully integrate acquisitions, or to complete divestment agreements.

(iii) Financial risks

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

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

General cost inflation in the resources sector is affecting both operations and projects, resulting in significant pressure on capital and operating costs.

(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 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.

(v) Sustainable development risks

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

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.

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

Corporate governance

The directors of Rio Tinto believe that highest standards of corporate governance are essential to its vision of global leadership in the mining and metals sector and have continued to apply the standards discussed under 'Corporate governance' on pages 67 to 76 of the 2011 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 Services 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. This has been reproduced on page 42 and forms part of this report.

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

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.

Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Rio Tinto, or industry results, to be materially different from any future results, performance or achievements 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 include, among others, 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 Australia and the United Kingdom 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 Services 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.

(a) Net impairment charges of US$94 million in 2012 relate mainly to the Specialty Alumina and Cable divisions which are treated as disposal groups held for sale in the statement of financial position. Divestment of the Specialty Alumina division was completed on 1 August 2012.

Impairment charges of US$9,766 million (including US$592 million after tax relating to the Group's investments in equity accounted units) for the year ended 31 December 2011 related mainly to the Group's aluminium business: US$9,182 million, the Group's diamond business: US$467 million (net of impairment reversals of US$176 million) and US$117 million in other impairments less reversals.

All impairments were measured based upon an assessment of fair value.

In measuring the amount of impairment on the aluminium business, the Group compared the carrying value with its fair value less costs to sell ('FVLCS'), assessed using discounted cash flow techniques. This was in accordance with the requirements of IAS 36 'Impairment of Assets' since, in the Group's view, the aluminium business' value in use was lower than its FVLCS. The FVLCS of the aluminium business was lower than its carrying value, which resulted in impairment of US$9,182 million; including to investments in equity accounted units of US$579 million. A portion of the goodwill impairment arose on goodwill allocated to aluminium assets, now reported within Other Operations, following the change in managing structure for these businesses announced on 17 October 2011.

Of the net impairments to the Group's diamond businesses, US$456 million relates to Argyle and was caused by changes in assumptions about future capital costs required to complete the Argyle underground project. In addition, recovery in prices resulted in a US$112 million reversal of impairment relating to Diavik.

(b) Losses arising on the consolidation and disposal of interests in businesses for the six months ended 30 June 2012 include a US$38 million loss on consolidation of Ivanhoe Mines Limited ('Ivanhoe') on 24 January 2012. On 2 August 2012, Ivanhoe was renamed Turquoise Hill Resources Ltd. ('Turquoise Hill').

The loss represents the excess of the historic cost of acquiring the Group's share of the assets and liabilities of Turquoise Hill excluding Oyu Tolgoi LLC (OT) ('the non OT assets') over the provisional fair value ascribed to those assets. The Group's interest in the non OT assets is held through its investment in Turquoise Hill.

Profits arising on the disposal of interests in businesses for the year ended 31 December 2011 relate principally to the divestment of the Group's talc business and of its Colowyo mine. Refer to 'Acquisitions and disposals' on page 37.

(c) Profits on disposal of interests in undeveloped projects in 2012 relate principally to the disposal of the Group's investments in Extract Resources Limited and Kalahari Minerals plc.

(d) Taxation is net of a credit of US$1,114 million arising from recognition of a deferred tax asset following introduction of the Minerals Resource Rent Tax ('MRRT') on 1 July 2012. Refer to prima facie tax reconciliation on page 36.

(e) 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 1,851.9 million (30 June 2011: 1,948.8 million; 31 December 2011: 1,923.1 million), being the average number of Rio Tinto plc shares outstanding of 1,416.1 million (30 June 2011: 1,513 million; 31 December 2011: 1,487.3 million), plus the average number of Rio Tinto Limited shares outstanding not held by Rio Tinto plc of 435.8 million (30 June 2011: 435.8 million; 31 December 2011: 435.8 million). The profit and loss figures used in the calculation of basic and diluted earnings per share are based on profits and losses attributable to owners of Rio Tinto.

For the purposes of calculating diluted earnings/(loss) 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.

(a) Refer to Statement of comprehensive income for further details.

(b) Rio Tinto gained control of the non OT assets on 24 January 2012 ('the acquisition date') when its share in Ivanhoe Mines Limited ('Ivanhoe') reached 51 per cent. The Group had gained control of OT in December 2010 by virtue of its contractual rights which permit it to exercise control over certain policies and activities of OT. On 2 August 2012, Ivanhoe was renamed Turquoise Hill Resources Ltd. ('Turquoise Hill').

The $2,883 million relating to newly consolidated companies represents non-controlling interests in the non OT assets, of which US$1,439 million relates to the 49 per cent share of Turquoise Hill's non Rio Tinto Shareholders in net loans receivable from Rio Tinto group companies.

Refer to 'Acquisitions and disposals' on page 37 for further information.

(c) The majority of the adjustments to equity held by Rio Tinto arrive from Chalco's acquisitions of shares in Simfer Jersey Ltd. ('Simfer'), as set out in the Simandou Joint Development Agreement ('SJDA'). Chalco made a payment of US$1.35 billion on 24 April 2012 in exchange for an equity interest of 47 per cent in Simfer, with a subsequent cash call of US$200 million, which resulted in Chalco being issued shares in Simfer equal to its equity interest. The transaction resulted in an adjustment to retained earnings attributable to owners of Rio Tinto of US$1.01 billion, relating to the excess of consideration received over the carrying value of Rio Tinto's interest transferred.

(b) The purchase of Riversdale was treated as a step acquisition. Non-controlling interests of US$1,498 million arose at the acquisition date, when Rio Tinto's share in Riversdale reached 52.6 per cent. Subsequent to the acquisition date, non-controlling interests reduced by US$1,487 million as Rio Tinto increased its interests in Riversdale to 99.8 per cent. An amount of US$479 million was recognised directly in equity in relation to Rio Tinto's interests purchased after the acquisition date, representing the excess of consideration paid to acquire these additional shareholdings, over non-controlling interests acquired. Refer to 'Acquisitions and disposals' on page 37 to 39 for further information.

(c) A reduction of US$254 million in non-controlling interests arose as Rio Tinto increased its economic share in Oyu Tolgoi through the acquisition of additional interests in Ivanhoe Mines Limited. Adjustments to retained earnings attributable to owners of Rio Tinto of US$59 million related to the aggregate excess of consideration paid for the additional investments in Ivanhoe, over the value of the additional economic share acquired in Oyu Tolgoi.

(b) The purchase of Riversdale was treated as a step acquisition. Non-controlling interests of US$1,498 million arose at the acquisition date, when Rio Tinto's share in Riversdale reached 52.6 per cent. These non-controlling interests were reversed as Rio Tinto increased its interests in Riversdale to 100 per cent. An amount of US$479 million was recognised directly in equity in relation to Rio Tinto's interests purchased after the acquisition date, representing the excess of consideration paid to acquire these additional shareholdings, over non-controlling interests acquired. Refer to 'Acquisitions and disposals' on page 37 to 39 for further information.

(c) A reduction of US$339 million in non-controlling interests arose as Rio Tinto increased its economic share in Oyu Tolgoi through the acquisition of additional interests in Ivanhoe Mines Limited. Adjustments to retained earnings attributable to owners of Rio Tinto of US$129 million related to the aggregate excess of consideration paid for the additional investments in Ivanhoe, over the value of the additional economic share acquired in Oyu Tolgoi. Refer to 'Acquisitions and disposals' on pages 37 to 39 for further information.

(d) In relation to the Group's purchase of an additional stake in Coal & Allied, adjustments to retained earnings of US$185 million were made for the excess of consideration paid to acquire shareholdings of US$45 million from non-controlling interests.

Reconciliation with Australian Accounting Standards

The Group's financial statements have been prepared in accordance with IFRS as adopted by the European Union ('EU IFRS'), 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 EU 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 EU 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$537 million at 30 June 2012 (31 December 2011: US$537million; 30 June 2011: US$581 million).

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

(a) The Group updated its definition of net debt in 2011, such that it is stated net of the impact of certain funding arrangements relating to EAUs and partially owned subsidiaries (EAU funded balances). This modification 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. Following consolidation of Turquoise Hill Resources Ltd. ('Turquoise Hill', formerly Ivanhoe Mines Limited) on 24 January 2012, EAU funded balances in respect of Turquoise Hill and Oyu Tolgoi have been eliminated.

(b) Relates to the consolidation of Turquoise Hill on 24 January 2012. Refer to 'Acquisitions and disposals' note on page 37.

(c) Total borrowings are combined with other current financial liabilities of US$164 million (31 December 2011: US$184 million; 30 June 2011: US$302 million) and non-current financial liabilities of US$139 million (31 December 2011: US$172 million; 30 June 2011: US$346 million) in the statement of financial position.

(a) Impairment in investments in equity accounted units is net of tax credits of US$349 million for the year ended 31 December 2011.

(b) Minerals Resource Rent Tax ('MRRT') is an additional tax on profits from the mining of iron ore and coal in Australia, which came into effect on 1 July 2012. In computing MRRT liabilities, a deduction is given in respect of the market value of the mining assets as at 1 May 2010. A deferred tax asset is recognised on the temporary difference between the amount that is deductible for tax purposes and the carrying value of the assets in the accounts, to the extent that its recovery is probable. This temporary difference will reverse over the life of the mines.

(c) This tax reconciliation relates to the Group's parent companies, subsidiaries and proportionally consolidated units. The Group's share of profit of equity accounted units is net of tax charges of US$308 million (30 June 2011: US$320 million; 31 December 2011: US$507 million).

Acquisitions and disposals

30 June 2012

Acquisitions

Consolidation of Turquoise Hill Resources Ltd. (formerly Ivanhoe Mines Limited) excluding Oyu Tolgoi LLC

On 17 January 2012, Rio Tinto exercised its subscription right for anti-dilution. The subscription right entitled Rio Tinto to be issued 439,216 new shares in Ivanhoe Mines Limited ('Ivanhoe') at a price of approximately US$19.38 per share, for total consideration of US$8 million, increasing the Group's share in Ivanhoe to 48.97 per cent (from the 48.94 per cent ownership at 31 December 2011 after dilutive activity).

On 24 January 2012 ('the acquisition date'), Rio Tinto purchased 15,100,000 shares of Ivanhoe from the market (two sellers in a privately negotiated share purchase transaction), to increase its holding in Ivanhoe from 48.97 per cent to 51.01 per cent. The shares were purchased for an aggregate of US$299 million (C$302 million) at a price per share of US$19.79 (C$20.00). After completion of the share purchase, Rio Tinto owned 377,397,658 common shares in Ivanhoe.

The 24 January 2012 acquisition gave Rio Tinto control of the assets in Ivanhoe other than those relating to Oyu Tolgoi LLC ('OT'), which are primarily copper, gold and coal mining properties along with other exploration properties. The Group had gained control of OT in December 2010 by virtue of its contractual rights which permit it to exercise control over certain policies and activities of OT.

Rio Tinto's move to a majority stake in Ivanhoe reinforced its commitment to developing OT as a low cost, long life asset in a sustainable and mutually beneficial manner with the Government and people of Mongolia. On 2 August Ivanhoe was renamed Turquoise Hill Resources Ltd. ('Turquoise Hill').

100 per cent of the identifiable assets and liabilities of Turquoise Hill not related to OT ('non OT assets') were consolidated on 24 January 2012.

Due to the complexity of the valuation process, fair values on consolidation are provisional and will be subject to further review during the 12 months from the date on which the Group gained control of the non OT assets of Turquoise Hill.

Fair values on consolidation of the identifiable non OT assets and liabilities were provisionally estimated as follows.

Acquisitions and disposals (continued)

As required by IFRS 3, the identifiable assets and liabilities exclude balances receivable by Turquoise Hill from OT and balances payable to Rio Tinto by Turquoise Hill. Under IFRS 3, such balances are deemed to be 'settled' at acquisition as they eliminate on consolidation. There was, however, no actual settlement of the balances and they remain due and payable. The element of the US$299 million cost of the additional two per cent interest in Turquoise Hill acquired which is deemed to relate to these balances is included in the US$394 million inflow on the acquisition of subsidiaries line of the cash flow. Shareholder loans of US$3.3 billion due from OT to Turquoise Hill were included in the Group's external borrowings at 31 December 2011 and there were other immaterial balances between the non OT assets and Rio Tinto subsidiaries which were included in the Group's receivables and payables. At the date of gaining control these amounts totalled US$2.9 billion and eliminated with the newly consolidated balances of Turquoise Hill. Where applicable, the interest rate payable on these balances was deemed to be a market rate and there was therefore no gain or loss on deemed settlement.

Non-controlling interests arise from the 49 per cent of the non OT assets of Turquoise Hill not owned by Rio Tinto and from the portions of the assets and liabiIities of Turquoise Hill subsidiaries not owned 100 per cent by Turquoise Hill. Non-controlling interests are recognised at their proportionate share of the fair value of the identifiable assets and liabilities of the companies in which they hold an interest.

Goodwill arising on consolidation of US$156 million comprises control premium of US$124 million and US$32 million calculated in accordance with the requirement in IFRS to recognise a deferred tax liability on the difference between the provisional fair value of newly consolidated assets and liabilities and their tax base. This goodwill is not deductible for tax purposes.

For the period since acquisition, sales revenue and results for the non OT assets were not material to the consolidated income statement, and accordingly the impact of consolidating the non OT assets on 1 January 2012 rather than 24 January 2012 would also not have been material.

30 June and 31 December 2011

Acquisitions

Rio Tinto Coal Mozambique (formerly Riversdale Mining Limited)

On 8 April 2011, ('the acquisition date'), Rio Tinto acquired a controlling 52.6 per cent interest in Riversdale Mining Limited ('Riversdale'). Subsequent to the acquisition date, Rio Tinto continued to increase its interest in Riversdale and on 7 July 2011, its interest increased to 100 per cent; consideration paid for the remaining 47.4 per cent was US$1,977 million. Riversdale was delisted on 7 July 2011 and subsequently renamed Rio Tinto Coal Mozambique ('RTCM'). Due to the mutual proximity of the dates of individual increases in Rio Tinto's shareholding prior to the acquisition date, the transactions were accounted for as an acquisition taking place in only two stages, first the acquisition of a controlling interest on 8 April 2011, and secondly the purchase of additional interests after the acquisition date.

Provisional fair values on consolidation were determined for RTCM at 30 June 2011. The fair values were finalised by 8 April 2012, 12 months after the acquisition date.

Cash flows relating to the Group's purchase of its interest in RTCM during 2011 are allocated between investing and financing activities in accordance with the presentation requirements for staged acquisitions under IAS 7 'Cash flow statements'. In the interim Financial Statements for the six months ended 30 June 2011, all cash flows relating to the purchase of interests in RTCM were included within investing activities. Comparative figures for the six months ended 30 June 2012 have been restated accordingly. Goodwill arising on acquisition comprises US$530 million, being Rio Tinto's 52.6 per cent share at the acquisition date, of the amount calculated in accordance with IFRS to recognise a deferred tax liability on the difference between the provisional fair value of newly consolidated assets and liabilities and their tax base.

Hathor Exploration Limited

During 2011, between April and October, Rio Tinto built up a 5.8 per cent interest in Hathor Exploration Limited ('Hathor'), a uranium exploration company listed on the Toronto Stock Exchange. In October, an all cash offer was made for the remaining shares. On 30 November 2011 the conditions of the offer were satisfied and Rio Tinto acquired a controlling interest of 70.2 per cent of Hathor. By 31 December 2011 the Group's ownership had reached 88.0 per cent; by 12 January 2012 the remaining 12.0 per cent was acquired and Hathor has since been delisted from the Toronto Stock Exchange. Due to the mutual proximity of the dates of individual increases in Rio Tinto's shareholding subsequent to the acquisition date, and before the end of the year, these transactions were accounted for as taking place in one stage, at 30 November ('the acquisition date'), resulting in an ownership interest of 88 per cent being recognised at the acquisition date.

Fair values recognised on acquisition were provisional and remain subject to finalisation within 12 months of the acquisition date.

Goodwill arising on acquisition comprises US$150 million, being Rio Tinto's 88 per cent share of the amount calculated in accordance with IFRS to recognise a deferred tax liability on the difference between the provisional fair value of newly consolidated assets and liabilities with their tax base.

Ivanhoe Mines Limited

During the year ended 31 December 2011, Rio Tinto increased its ownership of shares in Ivanhoe Mines Limited ('Ivanhoe') as follows:

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, 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, and a guarantee from British Alcan Aluminium plc to the British Alcan Pension Plan, covering the contributions due from participating employers up to a PPF funding level of 105 per cent.

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 statement of financial position date

Refer to the note on acquisitions and disposals on pages 37 to 39 for events after the statement of financial position date in relation to acquisitions and disposals.

On 20 July 2012, Turquoise Hill Resources Ltd ('Turquoise Hill', formerly Ivanhoe Mines Limited) announced the successful completion of a US$1.8 billion rights offering for common shares, which was fully subscribed by both Rio Tinto and non-controlling shareholders. As a result, proceeds from issue of shares to non-controlling interests of US$0.9 billion will be recognised as a financing item in the Group statement of cash flows. As a result of the offering Rio Tinto's ownership in common Turquoise Hill shares increased to 510,968,850, maintaining its ownership of approximately 51 per cent of outstanding common shares.

Divestment of the Specialty Alumina division was completed on 1 August 2012.

Other than the items relating to acquisitions and disposals referenced above, no events were identified after the statement of financial position date which could be expected to have a material impact on the consolidated interim financial statement included in this report.

Basis of preparation

The consolidated interim financial statements included in this report are unaudited and have been prepared in accordance with IAS 34 'Interim financial reporting' as adopted by the European Union ('EU'), the Disclosure and Transparency Rules of the Financial Services Authority 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).

Accounting policies

The EU IFRS 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 to 31 December 2011.

The financial information by business unit and the geographic analysis of sales by destination provided on pages 9 and 35 of this press release, respectively, satisfy the disclosure requirements of IFRS 8 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, the directors have a reasonable expectation that the Group has adequate resources to continue in operational existence for the forseeable future. The Group therefore continues to adopt the going concern basis in preparing its consolidated interim financial statements.

Status of financial information

These consolidated interim financial statements do not comprise statutory accounts within the meaning of Section 434 of the Companies Act 2006.

Financial information for the year to 31 December 2011 has been extracted from the full financial statements prepared under the historical cost convention, as modified by the revaluation of certain derivative contracts, financial assets and post retirement assets and liabilities, as filed with the Registrar of Companies. The Auditors' report on the full financial statements for the year to 31 December 2011 was unqualified and did not contain statements under section 498 (1) (regarding adequacy of accounting records and returns), or under section 498 (3) (regarding provision of necessary information and explanations) of the United Kingdom Companies Act 2006.

Directors' declaration of responsibility

In the directors' opinion:

The consolidated interim financial statements and 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 Services 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 22 December 2010 (as amended on 17 February 2012), using the most appropriate accounting policies for Rio Tinto's business and supported by reasonable and prudent judgements.

The consolidated interim financial statements and notes give a true and fair view of the Rio Tinto Group's financial position as at 30 June 2012 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 report includes a fair review of the information required by DTR 4.2.7R and DTR 4.2.8R, namely:

- an indication of important events that have occurred during the first six months and their impact on the condensed set of 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 to Rio Tinto plc and Rio Tinto Limited ('the Companies')

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 the Companies to review the condensed set of consolidated interim financial statements in the half-yearly report of the Rio Tinto Group (comprising the Companies and their subsidiaries, associates and joint ventures) for the six months ended 30 June 2012, which comprises the Group income statement, Group statement of comprehensive income, Group statement of cash flows, Group statement of financial position, 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 half-yearly report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial information.

Directors' responsibilities

The half-yearly financial report, is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the half-yearly financial report in accordance with the Disclosure and Transparency Rules of the United Kingdom's Financial Services Authority and the Australian Corporations Act 2001 as amended by the Australian Securities and Investments Commission Order dated 22 December 2010 (as amended on 17 February 2012).

As disclosed in Note 1 'Principal Accounting Policies' of the 2011 Annual report, the financial statements of the Group are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of consolidated interim financial statements included in this half-yearly financial report has been prepared in accordance with International Accounting Standard 34, 'Interim Financial Reporting', as adopted by the European Union.

Our responsibility

Our responsibility is to express to the Companies a conclusion on the interim financial information in the half-yearly financial report based on our review. PricewaterhouseCoopers LLP have prepared this report, including the conclusion, for and only for Rio Tinto plc for the purpose of the Disclosure and Transparency Rules of the Financial Services Authority and PricewaterhouseCoopers have prepared this report, including the conclusion, for and only for Rio Tinto Limited for the purpose of the Australian Corporations Act 2001 as amended by the Australian Securities and Investments Commission Order dated 22 December 2010 (as amended on 17 February 2012) 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) 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 ASRE 2410 "Review of a Financial Report Performed by the Independent Auditor of the Entity". 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.

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 condensed set of consolidated interim financial statements in the half-yearly financial report for the six months ended 30 June 2012 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Services 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 half-yearly financial report of Rio Tinto Limited is not in accordance with the Australian Corporations Act 2011 including:

a) giving a true and fair view of the consolidated entity's financial position as at 30 June 2012 and of its performance for the half year ended on that date; and

b) complying with International Accounting Standard 34 as adopted by the European Union and the Australian Corporations Act 2011 as amended by the Australian Securities and Investments Commission Order dated 22 December 2010 (as amended on 17 February 2012).

Notes:

a) The maintenance and integrity of the Rio Tinto Group website is the responsibility of the directors; the work carried out by the auditors does not involve consideration of these matters and, accordingly, the auditors accept no responsibility for any changes that may have occurred to the financial statements since they were initially presented on the website.

b) Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.
