4QOR 2007

Rio Tinto PLC 16 January 2008 Date: 16 January 2008 Ref: PR596g Fourth quarter 2007 operations review Commenting on the quarter and full year production results, chief executive Tom Albanese said: 'Rio Tinto has pulled out all the stops to boost production in 2007 while our safety record has continued to improve. Investment to expand capacity in recent years is paying off with record volume growth in many commodities. We are driving the business at record pace, as these strong numbers clearly show. 'In 2007, we set annual production records for iron ore, bauxite, alumina, aluminium, refined gold, and refined copper on a like for like basis. With significant expansions in iron ore and aluminium and the contribution of the Alcan acquisition, which created the world's leading aluminium producer, we are set to see an acceleration of this growth in 2008. 'Against a background of record prices for many of our commodities and with a strong outlook for the demand for our products in the developing markets, we look forward with confidence.' • Rio Tinto's iron ore production set a new annual record at 179 million tonnes in 2007. On an attributable basis 2007 iron ore production was 145 million tonnes, a nine per cent increase on the 2006 total. • Fourth quarter attributable iron ore production was also a record, 11 per cent ahead of the fourth quarter of 2006 and seven per cent up on the previous quarter of 2007. • The Pilbara operations continued their rapid expansion with the Hamersley mines raising production by 17 per cent compared with the fourth quarter of 2006. At the end of December 2007 the Pilbara ports were operating at a rate of 190 million tonnes per annum (164 million tonnes on an attributable basis). • Rio Tinto's newest iron ore mine, Hope Downs, commenced production in November 2007, three months ahead of schedule. With the first expansion already approved, it is expected to reach 30 million tonnes annual capacity in 2009 - a rapid and sizeable increment to production in the Pilbara. • Fourth quarter bauxite, alumina and aluminium production were at record levels, increasing by 74 per cent, 133 per cent and 287 per cent respectively compared with the same quarter of 2006. This followed the Alcan acquisition and its subsequent integration with effect from 24 October 2007. On a proforma basis, excluding the Alcan acquisition, quarterly and annual production records were set for bauxite and aluminium. • Mined copper production was five per cent higher than the third quarter of 2007 primarily reflecting increased throughput at Kennecott Utah Copper but decreased by 14 per cent compared with the same quarter of 2006, mainly due to lower grades at Kennecott Utah Copper and Northparkes. • Rio Tinto's position as a significant gold producer was confirmed by its 2007 share of mined gold production of 1.2 million ounces, a 23 per cent increase over 2006. • Fourth quarter production of refined copper and refined gold rose 65 per cent and 98 per cent respectively above the 2006 fourth quarter level, reflecting a full quarter of production at the Kennecott Utah Copper smelter after the scheduled maintenance in the fourth quarter of 2006. • Fourth quarter uranium production was 13 per cent higher than the prior quarter but 14 per cent lower than the 2006 comparative period. The Ranger operation processed higher grade ore following the implementation of dewatering strategies and optimisation of the mine plan, offsetting reduced Rossing production due primarily to lower grades. All currency figures in this report are US dollars unless otherwise stated IRON ORE AND IRON Rio Tinto share of production (000 tonnes) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Hamersley 28,782 +17% +6% 107,828 +16% Robe River 7,529 +3% +18% 27,301 -3% IOC (pellets and concentrate) 2,248 -11% -5% 7,768 -18% In an iron ore market as tight as ever experienced, the success of the Pilbara Blend product was evidenced by sales achieving the benchmark price throughout the year. In December 2007, Rio Tinto announced it would place up to 15 million tonnes of iron ore in the spot market in 2008, recognising both very strong demand for iron ore and the gap between benchmark and spot prices, under which Rio Tinto has made sales at up to $190 per tonne (compared with the current equivalent benchmark price of $85 per tonne). In November 2007, Rio Tinto announced the approval of the $2.4 billion development of two new mines, Brockman 4 and Mesa A (Rio Tinto share $2.0 billion), with eventual annual production expected to reach 22 million tonnes and 25 million tonnes respectively. Both mines will commence production in 2010, and Brockman 4 has potential to be expanded to 36 million tonnes annual capacity. Plans were unveiled in the first half of 2007 to lift iron ore production capacity from the Pilbara to 320 million tonnes per annum by 2012, and a conceptual roadmap was outlined in November 2007 to add a further 100 million tonnes per annum in the Pilbara. A feasibility study to 320 million tonnes per annum is well underway and will be completed in 2009, and the preference is to expand port facilities at Cape Lambert. In addition, a $71 million feasibility study was approved for Hope Downs 4, as part of the project to increase Pilbara annual capacity to 320 million tonnes in 2012. Hamersley and Robe River The record production and sales figures for the quarter and the year were achieved as the cumulative effect of expansions and improvements to the supply chain flowed through the Pilbara system. This result was achieved despite a 30 hour impact on shipping and rail from a cyclone in late December. Fourth quarter rail performance showed a 14 per cent increase on the previous quarter, setting a new record for tonnes moved by rail. Mainline trials of automated train operations underway near Tom Price have so far proved successful and this project remains on track for wider implementation. A long-term lease was established to underpin construction of the purpose-built Remote Operations Centre near Perth's domestic airport, which will eventually see rail operations and other Pilbara-based functions transferred to Perth and is expected to lead to more efficient operations. HIsmelt The HIsmelt plant had a strong fourth quarter with production of 44,789 tonnes. The plant reached operation levels approaching nameplate capacity in December. This brought the annual production total to 114,870 tonnes for 2007 from 88,733 in 2006, as the plant ramps up to 800,000 tonnes per annum nameplate capacity. Iron Ore Company of Canada Production of pellets and concentrates at the Iron Ore Company of Canada was 11 per cent below the fourth quarter of 2006 and five per cent below the third quarter following planned maintenance on loading units. 2007 production was affected by the previously reported seven week strike which occurred in the first and second quarters of the year and concluded with a five year wage agreement. ALUMINIUM Rio Tinto share of production (000 tonnes) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Rio Tinto Alcan Bauxite 7,797 +74% +67% 21,022 +29% Alumina 1,853 +133% +173% 3,877 +19% Aluminium 835.4 +287% +286% 1,479.7 +75% Production records were set across the board in the Aluminium product group. Fourth quarter production of bauxite, alumina and aluminium increased sharply compared with the same quarter of 2006 reflecting the successful completion of the Alcan acquisition. Rio Tinto acquired the operating assets of Alcan with effect from 24 October 2007; production is shown as from that date. Bauxite Excluding the impact of the Alcan acquisition which accounted for 2,813 k tonnes in the fourth quarter, bauxite production at Weipa was 11 per cent above the fourth quarter of 2006 and seven per cent above the previous quarter, reflecting increased capacity from the commissioning of the second shiploader. 2007 Weipa bauxite production was at a record level. Alumina The Alcan acquisition contributed 1,144 k tonnes of alumina production in the fourth quarter. At the time of the acquisition, a 1.8 million tonne per annum expansion of Alcan's Gove refinery was nearing completion, bringing expected total capacity to 3.8 million tonnes per annum. The final months of the year saw continued ramping up of the expansion which is expected to reach full nameplate capacity by the end of 2008. Excluding the impact of the acquisition, alumina production increased by four per cent versus the prior quarter due to higher production at Yarwun which was 13 per cent higher than the third quarter due to maintenance activities in the previous quarter. Aluminium Excluding the Alcan acquisition, aluminium production was relatively stable versus the prior quarter with annual production records achieved at Bell Bay, Boyne Island and Tiwai Point. The Alcan acquisition accounted for 618k tonnes in the fourth quarter. COPPER Rio Tinto share of production Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Kennecott Utah Copper Mined copper (000 tonnes) 53.0 -20% +7% 212.2 -20% Refined copper (000 tonnes) 59.3 +145% -14% 265.6 +22% Molybdenum (000 tonnes) 3.0 -29% -14% 14.9 -11% Mined gold (000 ozs) 91 -25% +3% 407 -24% Refined gold (000 ozs) 133 +98% +3% 523 +13% Escondida Mined copper (000 tonnes) 103.8 +4% +3% 421.6 +7% Refined copper (000 tonnes) 15.8 -7% -2% 71.5 +77% Grasberg JV Mined copper (000 tonnes) 9.4 -40% +26% 28.4 -39% Mined gold (000 ozs) 103 +75% -30% 423 +345% Kennecott Utah Copper Lower metal head grades for both the quarter and the year compared with the respective 2006 periods impacted mined copper and gold production at Kennecott Utah Copper. Fourth quarter mined copper and gold production increased compared with the third quarter, when a five day planned maintenance shutdown at the concentrator took place. Refined copper production in the fourth quarter of 2007 was substantially higher than the 2006 comparative period, when major scheduled maintenance was undertaken on the smelter. Lower molybdenum production in the fourth quarter compared with the same period in 2006 was a result of lower ore grade and high limestone levels in the orebody. Escondida Mined copper for both the quarter and the full year was higher than the corresponding period of 2006, attributable to higher copper grades. Refined copper production in 2007 was 77 per cent higher than the prior year when the sulphide leach project was ramping up to capacity. Grasberg Variances in the metal sharing rates for 2007 were a major factor in lowering Rio Tinto's share of copper production and increasing its share of gold production in the fourth quarter and full year 2007, compared with the same periods of 2006. Other operations Lower copper production at Northparkes was attributable to an anticipated decline in grades in the E26 block cave, as the mine transitions towards production at E48. Lower grades at Palabora were partly compensated by higher throughput in the fourth quarter. In December 2007, Rio Tinto announced the approval of the development of the $300 million Eagle mine, a high grade nickel and copper deposit with first production expected to begin in late 2009. ENERGY US thermal coal Rio Tinto share of production (000 tonnes) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Rio Tinto Energy America 33,384 +2% +8% 125,083 0% Fourth quarter production was consistent with the same quarter of 2006 and eight per cent higher than the third quarter. Production records were set at the Spring Creek and Antelope mines as expansion projects near completion, offsetting lower production at Jacob's Ranch and Colowyo. Australian coal Rio Tinto share of production (000 tonnes) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Rio Tinto Coal Australia Hard coking coal 1,544 +2% -1% 6,179 +5% Other coal 5,642 -28% -4% 24,388 -22% In general, production at the Australian coal mines continued to be constrained by ongoing rail and port constraints in Queensland and New South Wales and reduced tonnage allotments in Queensland, which curtailed mined production, despite generally favourable market conditions. Production of hard coking coal was generally in line with the corresponding quarter of 2006 and the prior quarter, notwithstanding lower production at Kestrel as a result of mining through a known fault area. Full year production was five per cent higher than 2006. In New South Wales, reduced port throughput from coal chain infrastructure limitations continued to restrict output from all sites at Rio Tinto subsidiary Coal & Allied. An investment programme by the owners and operators of the coal ports at Newcastle and Dalrymple Bay on the eastern seaboard of Australia is expected to increase capacity in the second half of 2008 and into 2009. In December 2007, Rio Tinto announced the approval of the $991 million investment in the extension and expansion of the Kestrel Mine (Rio Tinto share $793 million). This is expected to extend the life of the mine and increase production to an average of 5.7 million tonnes per annum until 2031. Uranium Rio Tinto share of production (000 lbs) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Energy Resources of Australia 2,288 -10% +16% 8,011 +13% Rossing 1,216 -21% +8% 4,605 -16% Production at the Ranger mine was ten per cent lower compared with the same quarter of 2006, attributable to reduced access to higher grade ores. The successful implementation of various water disposal strategies, along with the optimisation of the mine plan throughout the year made higher grade ore available for processing. This resulted in 13 per cent higher production overall for 2007. Although there was an improvement of eight per cent on the previous quarter, lower grades at Rossing reduced fourth quarter and full year production compared with the same periods of 2006. DIAMONDS AND MINERALS Diamonds Rio Tinto share of production (000 carats) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Argyle 5,995 -25% +23% 18,744 -36% Diavik 1,766 +18% -6% 7,166 +22% Argyle's production improved on the previous quarter but was lower than the corresponding quarter of 2006 due to continued low feed grade associated with current mining locations. Variability in feed grade and production rates is expected to continue as the open-pit operation approaches the end of its life and the mine transitions to an underground operation. Production at Diavik was 18 per cent higher than the fourth quarter of 2006 as mining was almost exclusively from the higher grade A154S pipe in 2007 compared with a blend of A154S and A154N pipes in 2006. Production was six per cent lower than the third quarter due to the impact of winter weather. In November 2007, Rio Tinto approved additional funding of $563 million (Rio Tinto share $338 million) for the construction of the underground mining phase of the high margin Diavik mine, bringing the total approved to $787 million (Rio Tinto share $472 million). Diamond production from underground is due to commence in 2009 and continue beyond 2020. Minerals Rio Tinto share of production (000 tonnes) Q4 07 vs Q4 06 vs Q3 07 FY 07 vs FY 06 Borates 151 +5% +13% 560 +1% Titanium dioxide feedstocks 384 +1% +8% 1,458 +3% Fourth quarter production of borates and titanium dioxide feedstocks was broadly similar to the same quarter of the prior year as firm demand in Asia Pacific and Europe offset weakness in the US housing market. EXPLORATION AND EVALUATION There was a significant step up in exploration and evaluation expenditure with gross pre-tax cash costs in the twelve months of 2007 of $570 million, compared with $283 million in 2006. As part of Rio Tinto's continuing focus on optimising its portfolio, $253 million (pre-tax earnings) was realised from exploration divestments in 2007 compared with $46 million in 2006.
