Rio Tinto - half year results

Rio Tinto PLC 02 August 2007 Record cash flow from volume growth in strong markets • Cash flow from operations was at record levels for a first half, at $5,641 million, 11 per cent higher than the first half of 2006. • Underlying EBITDA* was a record $6,613 million, seven per cent above the first half 2006 level of $6,174 million. • Underlying earnings* of $3,529 million were six per cent below the corresponding period of 2006, which included $257 million from recognition of additional net tax assets. • Net earnings* were $3,253 million, down 14 per cent on the 2006 level of $3,796 million, mainly as a result of an impairment of Argyle. • Increased volumes from investment in additional capacity, particularly in iron ore, contributed $302 million to earnings. • Rising prices and strong demand for most products increased underlying earnings by $513 million. • Industry wide cost pressures impacted the business in the first half, reducing underlying earnings by $503 million, adjusted for inflation. • The Group's extensive organic growth pipeline led to record first half capital expenditure of $1.9 billion in 2007. The major iron ore expansions in Western Australia are on track, and studies are underway targeting further significant growth. • The approval in July of a two million tonne per annum expansion of the Yarwun alumina refinery in Queensland will strengthen the Group's position in alumina. • The accelerated expansion of the Hope Downs mine development to 30 million tonnes per annum was approved. • Recommended cash offer for Alcan to create a global aluminium industry leader was announced on 12 July 2007. Six months to 30 June 2007 2006 Change (All dollars are US$ millions unless otherwise stated) Cash flow from operations (incl. dividends from equity accounted units) 5,641 5,085 +11% Underlying EBITDA* 6,613 6,174 +7% Underlying earnings* 3,529 3,751 -6% Net earnings* 3,253 3,796 -14% Underlying earnings per share - US cents 272.6 278.7 -2% Earnings per share - US cents 251.3 282.0 -11% * Net earnings and underlying earnings relate to profit attributable to equity shareholders of Rio Tinto. Underlying earnings is defined and reconciled to net earnings on page 4. Underlying EBITDA excludes the same items that are excluded from underlying earnings. Chairman's comments Rio Tinto chairman Paul Skinner said, 'Demand for our products strengthened during the period, supported by a continued positive growth trend in the global economy and favourable demand conditions in China in particular. On the supply side, even though the mining industry is now into the fifth year of a broad cyclical upswing, its ability to meet that demand is still constrained by a scarcity of critical mining inputs and, in some cases, a lack of infrastructure and quality orebodies. These constraints are unlikely to ease in the near term. 'Against this background, the Group's operations performed well, although continuing industry-wide cost pressures impacted our margins and we remain focused on this key area. 'Rio Tinto's underlying earnings of $3,529 million in the first half of 2007 were our second highest first half results ever recorded. They were slightly below the previous half year when we recognised one-off tax benefits in excess of $250 million. The Group generated excellent cash flows of $5.6 billion from operations for the period, an average of almost one billion dollars per month, including dividends from equity accounted units. 'Our financial position is very strong, and our priority remains to use our financial resources for the value enhancing expansion of the business, consistent with our strategy of investing in large, long life resources capable of sustaining competitive advantage over time. 'In line with this strategy, we recently announced a recommended cash offer to acquire Alcan, the leading Canadian aluminium company, with an outstanding competitive smelting position based on hydro-power in the provinces of Quebec and British Columbia. We believe that Alcan's assets and culture fit well with our own, and that our offer, while compelling for Alcan shareholders, will create a global leader and add value for our own shareholders in the years to come. Not only does Alcan bring with it some of the world's lowest cost smelting operations and sizeable bauxite assets complementary to our own, but it also adds considerably to our growth pipeline in aluminium. 'The hydro-power assets of Alcan also complement our existing focus on positioning the Group to compete in a low-carbon environment, which saw the announcement in May of a major decarbonised energy joint venture with BP - Hydrogen Energy. 'Following the Alcan acquisition, which we aim to complete in the fourth quarter of 2007, our balance sheet will be more highly geared than currently, and we have therefore discontinued our existing capital management programme to focus on reinforcing our financial position. Since the start of 2005, we have returned $6.4 billion to shareholders through buybacks and a special dividend. 'We believe that the outlook for aluminium demand, and indeed demand for our other products, will remain positive while global economic growth remains strong. While there are concerns about the state of the credit markets, particularly in the USA, we do not anticipate that these will have a material short term impact on our markets.' Chief Executive's comments Tom Albanese, Rio Tinto's chief executive, said, 'Rio Tinto's long standing strategy, which is founded on the creation of long term shareholder value through the pursuit and operation of the world's best orebodies, remains unchanged. 'Rio Tinto has an industry leading pipeline of organic growth opportunities with in excess of $9 billion of committed projects across our portfolio and further significant projects under consideration. Our record programme of investment in organic growth continued in the first half of 2007, with particular emphasis on the expansion of our iron ore business in Australia. We are on target and schedule to reach 220 million tonnes per annum of managed iron ore production in the Pilbara in 2009, and are now undertaking studies into the potential to increase annual production capacity to 320 million tonnes. 'The long term growth trend in Chinese iron ore import demand will require continuing investment by the Group, and will open up further supply opportunities outside Australia, such as our high quality resource at Simandou in Guinea, where we are looking at developing a 70 million tonne per annum operation. 'Our portfolio of copper development projects made progress during the year, with the Oyu Tolgoi project moving a step closer to development approval, when the Mongolian Government announced its completion of a draft investment agreement in June. 'We are pleased that the Alcan board has recommended our cash offer to its shareholders. Our position in the global aluminium industry will be transformed by this transaction, which will make us number one global producer of aluminium and bauxite. We will be a leading alumina producer with the capability to become number one through organic expansion, such as our recently announced two million tonne per annum expansion of the Yarwun alumina refinery in Queensland. Our ongoing investment in common systems across Rio Tinto will accelerate the integration of Alcan into the wider Group. 'Following completion, we will be a bigger group and will be undertaking a strategic review to determine which of our businesses have the long term competitive position to be part of the enlarged Rio Tinto. The proceeds of any disposals, which are expected to exceed $10 billion, will be used to de-leverage our balance sheet. 'Operationally, the first six months of 2007 were demanding, as we again pushed our existing businesses to respond to strong market conditions by maximising production. 'At Argyle we have taken an impairment reflecting the impacts of industry cost pressures in Western Australia and difficult ground conditions. The revised capital budget of the project is now likely to be of the order of $1.5 billion. 'On balance, all our businesses have performed well, but we are alert to continuing industry-wide cost pressures, notably in Western Australia and in Queensland. Our iron ore business has experienced higher contractor and transportation costs particularly following the cyclones earlier this year, whilst infrastructure related costs at Rio Tinto Coal Australia have impacted margins in the Energy group. We are putting in place measures to mitigate the future impact of costs through productivity improvements, the sharing of best practice and a review of our functional and support costs.' Net earnings and underlying earnings To provide insight into the underlying performance of its business, Rio Tinto presents underlying earnings. The differences between underlying earnings and net earnings are set out in the table below. Six months ended 30 June 2007 2006 US$m US$m Underlying earnings 3,529 3,751 Items excluded from underlying earnings Impairment charges (314) - Other 38 45 Net earnings 3,253 3,796 Commentary on the Group financial results Underlying earnings of $3,529 million and net earnings of $3,253 million were $222 million and $543 million below the comparable measures for the first half of 2006. The principal factors explaining the movements are set out in the table below. Six months ended 30 June Underlying Net earnings earnings US$m US$m First half 2006 3,751 3,796 Prices 513 Exchange rates (118) Inflation (85) Volumes 302 Costs (503) Tax (370) Other 39 (222) (222) Impairment charges (314) Other (7) First half 2007 3,529 3,253 Prices and exchange rates Prices for major products were above those experienced in 2006. Compared with the first half of 2006 average copper prices were 13 per cent higher and average aluminium prices ten per cent higher. The strength of the global iron ore market was reflected in the 9.5 per cent increase in the benchmark price, which was mainly effective from 1 April 2007. The seaborne thermal and coking coal markets were also strong. Higher copper prices contributed $32 million to underlying earnings compared with the first half of 2006. This included the impact of changes in the copper price on the amount realised from provisionally priced sales, mostly at Escondida and Northparkes, which resulted in a contribution of $109 million to underlying earnings in the first half of 2007. This compared with a contribution of $291 million for the corresponding period of 2006. Molybdenum prices averaged $28 per pound in the first half of 2007, an increase of 19 per cent compared with the same period of 2006. There was movement in the US dollar in the first half of 2007 relative to the currencies in which Rio Tinto incurs the majority of its costs. The average Australian dollar rate was nine per cent stronger, the South African rand 14 per cent weaker and the Canadian dollar was relatively unchanged. The effect of these currency movements was to decrease underlying earnings relative to the first half of 2006 by $118 million. Volumes Higher sales volumes increased earnings by $302 million compared with the first half of 2006. The main contributors were the ramp-up of iron ore from the continued expansion of the Pilbara mines, in particular Yandicoogina, higher volumes of refined copper following the commissioning of the Escondida sulphide leach plant in the latter half of 2006 and higher gold production from higher grades at Grasberg. Costs Excluding the effects of inflation, higher costs reduced earnings by $503 million. Rio Tinto Coal Australia experienced intense cost pressures from infrastructure constraints and increased contractor and equipment hire charges while cyclones in the Pilbara raised contractor and transportation rates at the iron ore operations. Higher non-cash costs reduced earnings by $76 million. This was mostly attributable to the impairment reversal at Kennecott Utah Copper in 2006 which is now being depreciated. Tax The effective tax rate on underlying earnings, excluding equity accounted units, was 32 per cent compared with 22 per cent in the first half of 2006. The tax rate for the first half year of 2006 was reduced by 6.4 percentage points following recognition of $211 million of additional deferred tax assets, reflecting improved projections of long term taxable earnings from the Group's US operations; and following a $46 million reduction in deferred tax provisions as a result of a reduction in Canadian tax rates. Items excluded from underlying earnings A further impairment charge of $314 million after tax has been recognised at Argyle. The deterioration in value is mainly due to large increases in the estimated capital cost of the underground project including the effect of over-heated Western Australian construction industry conditions. In full year 2006, there was a net reversal of impairments of $44 million. Other exclusions from underlying earnings were net gains of $38 million ($45 million for the six months to 30 June 2006: $56 million in full year 2006). Cash flow Cash flow from operations, including dividends from equity accounted units, was a first half record at $5,641 million, 11 per cent higher than the first half of 2006. The Group continued to invest at high levels to grow the business. Net expenditure on property, plant and equipment and intangible assets was a first half record at $1,916 million during the first half of 2007. This included the major port, rail infrastructure and iron ore mine expansions in Western Australia, the ilmenite mine in Madagascar and the Diavik A418 dike construction. Dividends paid in the first half of 2007 of $837 million were $1,187 million lower than dividends paid in the first half of 2006, which included the special dividend totalling $1.5 billion. Capital management activity in the first half of 2007 comprised a $1,417 million buy back of Rio Tinto plc shares from the 2006/07 programme (net of $11 million proceeds from the exercise of options). In the first half of 2006 capital management totalled $1,098 million through the on-market buy back of Rio Tinto plc shares. Balance sheet The balance sheet remained strong during the period, despite record capital expenditure, with net debt increasing from $2,437 million at 31 December 2006 to $2,862 million at 30 June 2007. Debt to total capital remained at 11 per cent and interest cover was 77 times. In the first half of 2007, net assets increased by $2,562 million. The Rio Tinto plc share buy back reduced shareholder equity by $1,361 million. International Financial Reporting Standards (IFRS) IFRS require that the profit for the period reported in the income statement should also include earnings attributable to outside shareholders in subsidiaries. For the first half of 2007, the profit for the period was $3,401 million (2006 first half $3,968 million) of which $148 million (2006 first half $172 million) was attributable to outside shareholders, leaving $3,253 million (2006 first half $3,796 million) of net earnings attributable to Rio Tinto shareholders. Both 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 Dividends are determined in US dollars. The interim dividend is set at one half of the total dividends declared for the previous year excluding any special dividends. Therefore, interim dividends equivalent to 52 US cents per share (2006: 40 US cents per share) have been declared by Rio Tinto plc and Rio Tinto Limited. Rio Tinto plc dividends are declared and paid in pounds sterling and Rio Tinto Limited dividends are declared and paid in Australian dollars, converted at exchange rates applicable on Tuesday 31 July 2007. Rio Tinto plc shareholders will be paid an interim dividend of 25.59 pence per ordinary share (2006: 21.42 pence per share). Rio Tinto Limited shareholders will be paid an interim dividend of 60.69 Australian cents per ordinary share (2006: 52.48 Australian cents per share), which will be fully franked. The Board expects Rio Tinto Limited to be in a position to pay fully franked dividends for the reasonably foreseeable future. The respective dividends will be paid on Thursday 6 September 2007 to Rio Tinto plc shareholders on the register at the close of business on Friday 10 August 2007 and to Rio Tinto Limited shareholders on the register at the close of business on Tuesday 14 August 2007. The ex-dividend date for both Rio Tinto plc and Rio Tinto Limited will be Wednesday 8 August 2007. Dividends will be paid to Rio Tinto ADR holders on Friday 7 September 2007. As usual, Rio Tinto will operate its Dividend Reinvestment Plan, 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 Wednesday 15 August 2007.

IRON ORE First half First half Change Full year 2007 2006 2006 Production (million tonnes) 69.4 62.0 +12% 132.8 Gross sales revenue ($ millions) 3,736 2,975 +26% 6,938 Underlying earnings ($ millions) 1,099 944 +16% 2,251 EBITDA ($ millions) 1,941 1,652 +17% 3,936 Capital expenditure ($ millions) 973 874 +11% 1,981 Market conditions Global iron ore demand remained extremely strong in all markets during the first half of 2007, with the Chinese market very robust. In light of this continued strong demand, Rio Tinto announced its intention to undertake studies into a further expansion of its Pilbara operations' annual production capacity to around 320 million tonnes. Hamersley First half 2007 earnings of $861 million were $163 million above the first half of 2006. Production in the first half of 2007 was at record levels as Yandicoogina and other brownfield expansions continued to deliver additional tonnage. Increased production rates were achieved during the first half, despite scheduled shutdowns associated with the integration of major capacity upgrades. These recently completed major upgrades at Tom Price, Paraburdoo and Dampier Port performed well. Hamersley's first half earnings included a net loss of $24 million for HIsmelt (first half 2006 $13 million net loss) due to scheduled pre-production and marketing costs. Robe River First half earnings of $233 million were $36 million above the first half of 2006. Higher prices and volumes were partially offset by higher costs from increased demurrage and contractor rates. Iron Ore Company of Canada Earnings of $28 million were $26 million below the first half of 2006. Production of concentrates and pellets was 30 per cent below the first half of 2006 as a result of industrial disruption which lasted for approximately 52 days, and ended on 25 April. Rio Tinto Brasil Rio Tinto Brasil reported a loss of $1 million in the first half of 2007 compared with earnings of $6 million in the first half of 2006, as sales volumes were affected by low availability of third party transport. Other Iron ore projects are now reported within the product group. Higher expenditure was reported at the Simandou project in Guinea as the pre-feasibility study advanced. ENERGY First half First half Change Full year 2007 2006 2006 Production Coal (million tonnes) US 60.7 61.2 -1% 125.3 Hard coking coal 3.1 2.7 +15% 5.9 Other Australian 12.9 15.7 -18% 31.2 Uranium (000 lbs) 6,006 5,525 +9% 12,561 Gross sales revenue ($ millions) 2,161 2,051 +5% 4,240 Underlying earnings ($ millions) 245 374 -34% 707 EBITDA ($ millions) 546 705 -23% 1,366 Capital expenditure ($ millions) 223 316 -29% 582 US Coal - Rio Tinto Energy America (RTEA) RTEA's first half 2007 earnings of $46 million were $44 million below the first half of 2006. Improved prices were offset by higher cash costs, notably higher stripping costs, increased haul profiles and higher maintenance costs. In the first half of 2006 a $14 million tax credit was recognised as a deferred tax asset. There was no such credit recognised in 2007. US coal production during the first half of 2007 was consistent with the first half of 2006, with unusually wet spring weather slowing rail shipments and coal production. Asia Pacific seaborne coal markets Following severe wet weather in the Hunter Valley region of New South Wales in June 2007, Asian seaborne thermal coal prices rose sharply to peak at $70 per tonne in the first half of 2007. Issues relating to infrastructure controlled by external parties are likely to maintain market tightness for the foreseeable future. Rio Tinto Coal Australia Earnings of $177 million were $95 million below the first half of 2006, with higher coking coal volumes unable to compensate for lower thermal coal volumes, which were constrained by infrastructure issues and wet weather. Production of hard coking coal benefited from an improvement in the coking coal market but was restricted due to external infrastructure problems in Queensland. The New South Wales operations were impacted by heavy rains in June which resulted in the declaration of force majeure by Rio Tinto's subsidiary Coal & Allied. Reduced port throughput from infrastructure limitations led to continued delays in shipping and a resultant decrease in production as the effects were felt along the Hunter Valley coal chain. Uranium markets The uranium market has softened from its recent price highs of $135 per pound. Market sentiment continues to be positive, with supply disruptions likely to persist for longer than previously expected. Rossing Earnings of $44 million were $37 million above the first half of 2006, reflecting the benefit of higher realised prices. These more than compensated for reduced production volumes due to lower grades. Energy Resources of Australia The Rio Tinto share of ERA reported earnings of $2 million in the first half of 2007 was $6 million below the first half of 2006, due to lower sales volumes and higher costs associated with the heavy rains during the first quarter of 2007. The subsequent flooding of the operational pit 3 led to the declaration of force majeure on ERA's sales contracts. The full impact of rising uranium prices will only flow through to sales as new contracts come into effect. Other Energy projects are now reported within the product group. The increased charge in the first half of 2007 includes Rio Tinto's share of expenditure for the Hydrogen Energy joint venture. ALUMINIUM First half First half Change Full year 2007 2006 2006 Production Bauxite (000 tonnes) 8,462 7,658 +10% 16,139 Alumina (000 tonnes) 1,346 1,632 -18% 3,247 Aluminium (000 tonnes) 428.2 413.7 +3% 844.7 Gross sales revenue ($ millions) 1,749 1,658 +5% 3,493 Underlying earnings ($ millions) 406 369 +10% 746 EBITDA ($ millions) 739 673 +10% 1,365 Capital expenditure ($ millions) 120 114 +5% 236 Prices The average aluminium price of 126 cents per pound was ten per cent above the first half 2006 average price. The alumina market remained tight with spot prices trading at around $365 per tonne. Recent supply disruptions have not had any strong impact on the spot alumina market. The rate of Chinese alumina imports has decreased, as domestic production continues to grow rapidly. These effects, together with the impacts of other price movements, increased earnings by $79 million. Bauxite Half year bauxite production was ten per cent above the first half of 2006 reflecting severe weather conditions that occurred in the prior year and the commissioning of the second shiploader in late 2006. Alumina Alumina production at the Yarwun alumina refinery in the first half of 2007 was seven per cent higher than the corresponding period of 2006 due to improved process stability. Rio Tinto's overall share of alumina production in the first half of 2007 was 18 per cent lower than the same quarter of 2006 following the sale of its interest in the Eurallumina refinery in October 2006. Aluminium Production at the aluminium smelters during the first half of 2007 was three per cent above the corresponding half of 2006. Much of this improvement was attributable to the Tiwai Point smelter where production was eight per cent higher than the first half of 2006 when low rainfall in the hydropower catchment area resulted in cells being taken out of circuit. Production costs were adversely affected by higher input prices. COPPER First half First half Change Full year 2007 2006 2006 Production Mined copper (000 tonnes) 384.5 410.8 -6% 803.5 Refined copper (000 tonnes) 202.3 169.5 +19% 299.2 Mined molybdenum (000 tonnes) 8.5 7.9 +7% 16.8 Mined gold (000 oz) 606 461 +32% 1,003 Gross sales revenue ($ millions) 4,324 3,644 +19% 7,079 Underlying earnings ($ millions) 1,818 1,998 -9% 3,538 EBITDA ($ millions) 3,043 2,781 +9% 5,118 Capital expenditure ($ millions) 282 307 -8% 697 Prices The average copper price of 307 cents per pound was 13 per cent above the first half 2006 average price. This increased earnings by $32 million, net of the effects of provisional pricing movements, which were a credit to earnings of $109 million in the first half of 2007 compared with a credit of $291 million in the corresponding period of 2006. Kennecott Utah Copper First half earnings of $785 million were $248 million lower than the first half of 2006 due to lower volumes of molybdenum sales, higher non-cash costs and the absence of tax credits. In 2006 the operation benefited from a tax credit of $215 million, following recognition of deferred tax assets. Lower grades of copper and gold at Bingham Canyon, which were in line with the operation's expectations, resulted in mined copper production declining by 16 per cent compared with the first half of 2006. Molybdenum production increased by seven per cent compared with the corresponding half of 2006 as a result of higher recoveries, with molybdenum inventories replenished following a draw down in 2006. The smelter continued to operate at targeted levels with refined production of copper and gold consistent with the first half of 2006. Escondida Earnings of $835 million were $135 million above the first half of 2006. Refined copper production increased by 180 per cent compared with the first half of 2006 due to the ramp up of sulphide leach production in the latter half of 2006. Grasberg joint venture Earnings of $63 million were $2 million below the first half of 2006. Changes in the metal sharing rate for 2007 were a major factor in lowering Rio Tinto's share of copper production and increasing its share of gold production in the first half of 2007, compared with the same half of 2006. Higher gold grades also contributed to this positive variance. Kennecott Minerals Earnings of $56 million were $11 million above the first half of 2006. Higher volumes and higher prices were partly offset by the absence of a $10 million deferred tax asset recognised in 2006. Palabora Earnings of $32 million were $6 million below the first half of 2006, with improved volumes offset by higher cash costs. Northparkes Earnings of $93 million were $31 million below the first half of 2006. Copper production was 27 per cent below the first half of 2006, in line with an expected decline in grades in the E26 block cave as this resource nears the end of life ahead of bringing the new E48 block cave into production. Other Copper projects are now reported within the product group. Higher costs associated with projects including La Granja and Resolution reduced earnings by $39 million compared with the first half of 2006. The Oyu Tolgoi copper-gold project moved a step closer to development approval with the Mongolian Government's announcement that it had completed the draft Investment Agreement on 26 June 2007. The Agreement has been submitted to the Mongolian National Parliament. This is expected to be the final step in the Government's approval process. Approval will also be needed from the boards of Rio Tinto and Ivanhoe Mines, the Canadian joint venture partner. The agreement provides for the Mongolian Government to own a 34 per cent stake in the project. DIAMONDS AND MINERALS First half First half Change Full year 2007 2006 2006 Production Diamonds (000 carats) 11,446 15,530 -26% 35,162 Titanium dioxide (000 tonnes) 718 697 +3% 1,415 Borates (000 tonnes) 274 271 +1% 553 Salt (000 tonnes) 2,075 2,650 -22% 5,405 Talc (000 tonnes) 679 727 -7% 1,392 Gross sales revenue ($ millions) 1,823 1,663 +10% 3,461 Underlying earnings ($ millions) 212 233 -9% 407 EBITDA ($ millions) 584 524 +11% 1,062 Capital expenditure ($ millions) 415 253 +64% 617 This restructures the previous Diamonds and Industrial Minerals product groups from May 2007. Diamond markets Stocks accumulated by cutting centres in 2006 continued to be drawn down and some shortages of higher quality rough diamonds are starting to emerge. This is driving increasingly positive sentiment in the rough market, although expectations for the lower quality product are more subdued. Argyle Earnings of $29 million were $12 million below the first half of 2006. Lower prices for rough diamonds were only partly compensated by higher sales volumes and lower non-cash costs. Diavik Earnings of $64 million were $6 million below the first half of 2006. Record production at Diavik was achieved during the first half with strong throughput and continued higher grades contributing to the 30 per cent increase in production compared with the first half of 2006. 2006 earnings included a $21 million release of deferred tax provisions following a reduction in the Canadian corporate tax rate. Murowa Murowa broke even in the first half of 2007, compared with earnings of $2 million for the same period of 2006. Iron & Titanium Earnings of $79 million were $4 million below the first half of 2006. Global demand for titanium dioxide feedstocks remained firm in the first half of 2007 due to domestic shortages and heightened demand for use in the pigment industry. In 2006, a reduction in the Canadian corporate tax rate resulted in an $18 million release of deferred tax provisions. This did not recur in 2007. Rio Tinto Minerals Earnings of $60 million were $6 million above the first half of 2006 with higher prices and property sales offsetting the impact of a stronger Euro, lower volumes and increased costs. Other Diamonds and Minerals projects are now reported within the product group. This includes the potash project in Argentina which is in the final stages of feasibility study. OTHER OPERATIONS First half First half Change Full year 2007 2006 2006 Underlying earnings ($ millions) (4) 16 -125% 33 The sale of the last remaining gold inventories at Kelian generated earnings of $15 million in the first half of 2006, accounting for much of the above variance. At Kennecott Land's Project Daybreak, land sales remained constant. During the first half of 2007, over 300 residential lots were sold, in line with the corresponding period of 2006. OTHER ITEMS First half First half Change Full year 2007 2006 2006 Underlying earnings ($ millions) (260) (116) -124% (243) The increase in other items can be attributed to a higher technology spend, a higher settlement of claims by the captive insurer and the absence of accounting policy changes in 2007, compared with a positive impact on the first half of 2006. EXPLORATION AND EVALUATION First half First half Change Full year 2007 2006 2006 Post-tax credit / (charge) ($ millions) 25 (53) +147% (84) Central exploration and evaluation credits of $25 million, on a post-tax basis, were 147 per cent lower than the first half of 2006. Higher greenfield expenditure was offset by increased divestments including the sale of the Penasquito royalty rights.

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 cause 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 due to the revaluation of foreign currency working capital. They should therefore be used with care.

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 Australian IFRS include the residue of such goodwill, which amounted to US$736 million at 30 June 2007 (half year 2006: US$744 million; full year 2006: US$740 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 Australian IFRS.

Underlying earnings and Net earnings both represent amounts attributable to Rio Tinto shareholders. Items (a) to (f) below are excluded from Net earnings in arriving at Underlying earnings. (a) Gains and losses arising on the disposal of interests in businesses. (b) Charges and credits relating to impairment of non-current assets other than undeveloped properties. (c) Exchange gains and losses on US dollar debt and intragroup balances.

(f) Other credits and charges that, individually, or in aggregate if of a similar type, are of a nature or size to require exclusion in order to provide additional insight into underlying business performance. The impairment charge for the six months to 30 June 2007 relates to Argyle Diamonds and is based on an assessment of fair value less costs to sell. The deterioration in value is mainly due to large increases in the estimated capital cost of the underground project.

The analysis deals with: the sales revenue, profit before finance costs and taxation for subsidiary companies and proportionally consolidated units. The amounts presented for each product group exclude equity accounted units, but include the amounts attributable to outside equity shareholders. The product groups are consistent with those identified in the financial information by business unit data included on pages 7 and 8 of this news release. However, that information includes the results of equity accounted units and presents different financial measures. (b) The analysis of profit before finance costs and taxation includes the profit on disposal of interests in businesses (including investments), and impairment charges/reversals, which are excluded from Underlying earnings.

Contingent liabilities There were no material changes in contingent liabilities or contingent assets during the period. The disagreement with the Australian tax office relating to certain transactions undertaken in 1997 to acquire franking credits was settled on 14 June 2007, resulting in an additional tax charge of US$46 million for the six months to 30 June 2007.

Related party matters Transactions and balances with equity accounted units are summarised below. Purchases relate largely to amounts charged by equity accounted units for toll processing of bauxite and alumina. Sales relate largely to charges for supply of coal to jointly controlled marketing entities for onsale to third party customers.

The EU IFRS financial information has been drawn up on the basis of accounting policies consistent with those applied in the financial statements for the year to 31 December 2006. Certain prior year information has been reclassified to conform with the current year presentation. Exploration and evaluation costs charged against income were previously included in 'Cash used in investing activities' but are now included within 'Cash flow from operating activities'. As a result, exploration and evaluation costs expensed of US$117 million and US$273 million have been reclassified in the comparative figures for half year 2006 and full year 2006 respectively, within the Cash flow statement. Status of financial information These interim financial results do not have the status of statutory accounts within the meaning of Section 240 of the Companies Act 1985. Financial information for the year to 31 December 2006 has been extracted from the full financial statements prepared under the historical cost convention, as modified by the revaluation of certain derivative contracts and financial assets, as filed with the Registrar of Companies. The Auditors' report on the full financial statements for the year to 31 December 2006 was unqualified and did not contain statements under section 237(2) of the United Kingdom Companies Act 1985 (regarding adequacy of accounting records and returns), or under 237(3) (regarding provision of necessary information and explanations). Directors' declaration In the directors' opinion: The financial statements and notes have been prepared in accordance with the Listing Rules 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 dated 27 January 2006) (as amended on 22 December 2006) using the most appropriate accounting policies for Rio Tinto's business and supported by reasonable and prudent judgements. The financial statements and notes give a true and fair view of the Rio Tinto Group's financial position as at 30 June 2007 and of its performance, as represented by the results of its operations, recognised income and expense and its cash flows for the half year then ended. There are reasonable grounds to believe that each of the Rio Tinto Group, Rio Tinto Limited and Rio Tinto plc, has adequate financial resources to continue in operational existence for the foreseeable future and to pay its debts as and when they become due and payable. By order of the board G R Elliott Finance Director 2 August 2007 Auditors' Independence Declaration As lead auditor for the review of Rio Tinto Limited for the half year ended 30 June 2007, I declare that to the best of my knowledge and belief, there have been: a) no contraventions of the auditor independence requirements of the Corporations Act 2001 in relation to the review; and b) no contraventions of any applicable code of professional conduct in relation to the review. This declaration is in respect of Rio Tinto Limited and the entities it controlled during the period. Rob Hubbard Brisbane Partner 2 August 2007 PricewaterhouseCoopers Independent review report to Rio Tinto plc and Rio Tinto Limited ('the Companies') Introduction We have been instructed by the Companies to review the financial information of the Rio Tinto Group (comprising the Companies and their subsidiaries, associates and joint ventures) for the six months ended 30 June 2007 which comprises the Group interim balance sheet as at 30 June 2007, the Group interim statements of income, cash flows and recognised income and expense for the six months then ended and the related notes (including the financial information by Business Unit). We have read the other information contained in the interim report and considered whether it contains any apparent misstatements or material inconsistencies with the financial information. Directors' responsibilities The interim report, including the financial information contained therein, is the responsibility of, and has been approved by the directors of the Companies. The directors are responsible for preparing the interim report in accordance with the Listing Rules of the Financial Services Authority in the United Kingdom and the Australian Corporations Act 2001 as amended by the Australian Securities and Investments Commission Order dated 27 January 2006 (as amended on 22 December 2006). The Listing Rules of the London Stock Exchange require that the accounting policies and presentation applied to the interim figures should be consistent with those applied in preparing the preceding annual accounts except where any changes, and the reasons for them, are disclosed. This interim report has been prepared in accordance with International Accounting Standard 34, 'Interim financial reporting' as adopted by the European Union. Review work performed We conducted our review in accordance with guidance contained in Bulletin 1999/4 issued by the Auditing Practices Board for use in the United Kingdom. A review consists principally of making enquiries of Group management and applying analytical procedures to the financial information and underlying financial data and, based thereon, assessing whether the accounting policies and presentation have been consistently applied unless otherwise disclosed. A review excludes audit procedures such as tests of controls and verification of assets, liabilities and transactions. It is substantially less in scope than an audit performed in accordance with auditing standards and therefore provides a lower level of assurance than an audit. Accordingly we do not express an audit opinion on the financial information. This report, including the conclusion, has been prepared for and only for Rio Tinto plc for the purpose of the Listing Rules of the Financial Services Authority in the United Kingdom and for Rio Tinto Limited for the purpose of the Australian Corporations Act 2001 as amended by the Australian Securities and Investments Commission Order dated 27 January 2006 (as amended on 22 December 2006) 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. Review conclusion On the basis of our review we are not aware of any material modifications that should be made to the financial information as presented for the six months ended 30 June 2007. PricewaterhouseCoopers LLP PricewaterhouseCoopers Chartered Accountants Chartered Accountants London Brisbane 2 August 2007 2 August 2007 in respect of Rio Tinto plc in respect of Rio Tinto Limited Notes to financial information by business unit (Pages 7 and 8) The following changes have been made to the presentation of this information. Half year 2006 results have been reclassified accordingly. Product groups/business segments During 2007, Industrial Minerals and Diamonds were combined to form the Diamonds and Minerals product group. Other Project evaluation and other costs specifically attributable to product groups are now reported as part of product group earnings. Previously, these were reported centrally in 'Exploration and evaluation and Other items', respectively. Capitalised evaluation costs Capital expenditure by product group now includes capitalised evaluation costs. Business units have been classified according to the Group's management structure. Generally, this structure has regard to the primary product of each business unit but there are exceptions. For example, the Copper group includes certain gold 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. (b) EBITDA of subsidiaries and the Group's share of equity accounted units represents profit before: tax, net finance items, depreciation and amortisation. (c) Net earnings represent profit after tax for the period attributable to the Rio Tinto Group. Earnings of subsidiaries are stated before finance items but after the amortisation of the discount related to provisions. Earnings attributable to equity accounted units include interest charges and amortisation of discount. Earnings attributed to business units exclude amounts that are excluded in arriving at Underlying earnings. (d) Includes Rio Tinto's 75.7 per cent interest in Coal and Allied, which is managed by Rio Tinto Coal Australia, a 100 per cent subsidiary of Rio Tinto. (e) Includes Rio Tinto's interests in Rio Tinto Aluminum (100 per cent) and Anglesey Aluminium (51 per cent). (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) Diamonds includes Rio Tinto's interests in Argyle (100 per cent), Diavik (60 per cent) and Murowa (77.8 per cent). (h) Includes Rio Tinto's interests in Rio Tinto Borax (100 per cent), Dampier Salt (64.9 per cent) and Talc (100 per cent). (i) 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. (j) Depreciation figures include 100 per cent of subsidiaries' depreciation and amortisation and include Rio Tinto's share of the depreciation and amortisation of equity accounted units. Amounts relating to equity accounted units are deducted before arriving at the total depreciation and amortisation charge. Depreciation and amortisation includes US$15 million (2006 half year: US$15 million; 2006 full year: US$40 million) relating to deferred stripping costs. (k) Operating assets of subsidiaries comprise net assets before deducting net debt, less outside shareholders' interests which are calculated by reference to the net assets of the relevant companies (i.e. net of such companies' debt). For equity accounted units, Rio Tinto's net investment is shown.
