3 QOR 2007

Rio Tinto PLC 17 October 2007 Third quarter 2007 operations review • Near record iron ore production and shipments were achieved in the quarter, and Australian production was 11 per cent ahead of 2006 for the first nine months of the year, despite two derailments which impacted production for the third quarter. • Yandicoogina's capacity of 52 million tonnes per annum was reached during the third quarter, making it the largest single iron ore mine in Australia. The Hope Downs development of a 22 million tonne per annum mine and related infrastructure neared completion. • Margins in the Pilbara remain under pressure due to continuing increases in contractor and other mining input costs. Further measures have been put in place to ensure tighter control of manageable costs. • Mined copper production fell by six per cent compared with the same quarter of 2006, mainly attributable to lower grades, as expected, at Northparkes and Kennecott Utah Copper. • Production of refined copper was 30 per cent above the level of the third quarter of 2006 when the Kennecott Utah Copper smelter was shut down for scheduled maintenance. • Higher gold grades at Grasberg contributed to a 35 per cent increase in Rio Tinto's share of mined gold production compared with the third quarter of 2006. • Infrastructure challenges of congested ports and railways in Queensland and New South Wales continued to impact hard coking and thermal coal production in Australia in the third quarter, resulting in a decline of ten and 24 per cent, respectively, compared with the same quarter of the prior year. • Third quarter uranium production was five per cent higher than the 2006 comparative period, with the Ranger operation able to process higher grade ore following the successful implementation of dewatering strategies and optimisation of the mine plan. This offset a reduction in Rossing production from 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) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Hamersley 27,105 +7% -3% 79,046 +15% Robe River 6,381 -16% -8% 19,773 -5% IOC (pellets and concentrate) 2,376 -1% +37% 5,520 -20% In a very tight iron ore market, the Pilbara Blend product was successfully launched and is delivering improved product consistency to customers. The investment programme to increase production in the Pilbara region of Australia to 220 million tonnes per annum in 2009 remains on track, and early planning for a further increase to 320 million tonnes per annum capacity around 2012 to 2014 is under way, with a decision expected in 2008. Near record production and shipments were achieved in the quarter, and Australian production was 11 per cent ahead of 2006 for the first nine months of the year. Hamersley and Robe River Completion of the Junction South East expansion has boosted Yandicoogina's capacity to 52 million tonnes per annum, making it the largest single iron ore mine in Australia. The Hope Downs development of a 22 million tonne per annum mine and related infrastructure, including the Lang Hancock rail spur, neared completion and first ore is expected by early 2008. Increased production rates from completed brownfield expansions were achieved at Tom Price and Paraburdoo. The Dampier Upgrade B at Parker Point has been successfully completed and the expansion of Cape Lambert port to 80 million tonnes per annum capacity is under way. Robe River throughput was reduced by a planned 14 day maintenance shutdown of a car dumper at Cape Lambert. Two derailments in August impacted Hamersley's operations. The increase in shipments from the Pilbara in recent years has put the rail infrastructure under strain, resulting in a need to upgrade older sections of track. Planned maintenance was brought forward and completed for 12 sections of track with similar characteristics to reduce any risk of further derailments, and the purchase of replacement consists has also been expedited. HIsmelt The HIsmelt plant achieved its best quarter of production on record, following the major refurbishment and vessel reline of the previous quarter. The plant operated at up to 80 per cent of nameplate capacity and the three year ramp-up towards achieving 800,000 tonne per annum nameplate capacity in 2008 remains on target. Iron Ore Company of Canada Production of concentrates and pellets at the Iron Ore Company of Canada recovered further from the seven week strike which impacted the first and second quarters of the year. Pellet production was 42 per cent higher than the second quarter while third quarter concentrate production was 18 per cent higher despite catch-up maintenance following the strike. ENERGY US thermal coal Rio Tinto share of production (000 tonnes) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Rio Tinto Energy America 31,184 0% +3% 91,860 -1% Third quarter production was consistent with the same quarter of 2006. Coal inventories at power utilities have increased following lower demand for power combined with stronger shipments at the end of 2006. Spring Creek production set a new quarterly record following the successful implementation of the expansion project. Australian coal Rio Tinto share of production (000 tonnes) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Rio Tinto Coal Australia Hard coking coal 1,564 -10% -4% 4,635 +6% Other coal 5,855 -24% 0% 18,746 -20% Production of hard coking coal was severely impacted by ongoing port constraints and reduced tonnage allotments in Queensland, which curtailed mined production, despite generally favourable market conditions. In New South Wales, reduced port throughput from coal chain infrastructure limitations continued to impact all sites, offsetting a recovery in production at Rio Tinto subsidiary Coal & Allied, following heavy rains and the declaration of force majeure in June. 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. Uranium Rio Tinto share of production (000 lbs) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Energy Resources of Australia 1,980 +20% -11% 5,723 +26% Rossing 1,126 -14% +16% 3,389 -14% Production at the Ranger mine was 20 per cent higher in the third quarter, compared with the same quarter of 2006. The successful implementation of various water disposal strategies along with the optimisation of the mine plan made high grade ore available for processing. Lower grades at Rossing impacted third quarter production compared with the same period of 2006, although there was an improvement compared with the previous quarter. DIAMONDS AND MINERALS Diamonds Rio Tinto share of production (000 carats) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Argyle 4,865 -42% +10% 12,749 -39% Diavik 1,874 +10% -5% 5,399 +23% Argyle's production remained low in Q3 2007 due to continued low feed grade associated with current mining locations. Variability in feed grade and production rates will continue as the open-pit operation approaches the end of its life and the mine transitions to an underground operation. Production at Diavik was ten per cent higher than the third quarter of 2006 as mining continued to be predominately from the higher grade A154S pipe in 2007 compared with a blend of A154S and A154N pipes in 2006. Third quarter production was five per cent lower than the second quarter when record levels were achieved. Minerals Rio Tinto share of production (000 tonnes) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Borates 134 -2% -8% 408 0% Titanium dioxide feedstocks 356 +5% -3% 1,075 +4% Third 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. ALUMINIUM Rio Tinto share of production (000 tonnes) Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Rio Tinto Aluminium Bauxite 4,651 +15% +10% 13,113 +12% Alumina 679 -17% -1% 2,024 -17% Aluminium 216.2 0% 0% 644.4 +2% Third quarter bauxite production was 15 per cent above the third quarter of 2006 and ten per cent above the previous quarter, reflecting increased capacity from the commissioning of the second shiploader. Alumina production at Yarwun was consistent with the level of the third quarter of 2006. Rio Tinto's overall share of alumina production in the third quarter of 2007 was slightly ahead of the previous year on a comparable basis, but 17 per cent lower taking into account the sale of Eurallumina in October 2006. Production at the aluminium smelters was comparable with the third quarter of 2006 and the previous quarter of 2007. Year to date production was two per cent higher than 2006. COPPER Rio Tinto share of production Q3 07 vs Q3 06 vs Q2 07 9 mths 07 vs 9 mths 06 Kennecott Utah Copper Mined copper (000 tonnes) 49.5 -28% -11% 159.2 -20% Refined copper (000 tonnes) 68.7 +25% +1% 206.3 +7% Molybdenum (000 tonnes) 3.5 -26% -9% 11.9 -5% Mined gold (000 ozs) 88 -35% -27% 317 -24% Refined gold (000 ozs) 128 -6% -12% 390 -1% Escondida Mined copper (000 tonnes) 101.2 +25% -4% 317.9 +8% Refined copper (000 tonnes) 16.1 +77% -18% 55.7 +140% Grasberg JV Mined copper (000 tonnes) 7.5 -10% +34% 18.9 -38% Mined gold (000 ozs) 149 +1777% +54% 320 +787% Kennecott Utah Copper A five day planned maintenance shutdown at the concentrator in the third quarter impacted the quantity of ore treated, resulting in lower mined copper and gold production. Metal head grades for the quarter and the first nine months of 2007 were lower than their respective 2006 comparative periods. Lower molybdenum production in the third quarter compared with the same period in 2006 was a result of lower ore grade and high limestone levels in the orebody. Refined copper production in the third quarter of 2007 was higher than the 2006 comparative period attributable to the shutdown of the smelter for major maintenance having commenced in the third quarter of 2006. Escondida Third quarter mined copper production was 25 per cent above the corresponding quarter of 2006, reflecting higher grades and higher throughput in 2007 and the strike in 2006. Refined copper production increased by 77 per cent compared with the third quarter of 2006 when sulphide leach production was ramping up to capacity. Grasberg 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 third quarter of 2007, compared with the same quarter of 2006. Other copper operations Lower copper production at Northparkes was attributable to a significant decline in grades in the E26 block cave, as anticipated, as this resource nears the end of its life ahead of bringing E48 into production. EXPLORATION AND EVALUATION Pre-tax expenditure on exploration and evaluation charged to the profit and loss account in the first nine months of 2007 was $348 million compared with $175 million in same period of 2006. $76 million of this expenditure was charged against business unit earnings.

RIO TINTO SHARE OF PRODUCTION (continued) Production data notes (a) Rio Tinto sold its 56.2% share in Eurallumina with an effective date of 31 October 2006 and production data are shown up to that date. (b) Yarwun was previously known as Comalco Alumina Refinery. (c) In view of Rio Tinto Energy America's responsibilities under a management agreement for the operation of the Colowyo mine, all of Colowyo's output is included in Rio Tinto's share of production. (d) Through a joint venture agreement with Freeport-McMoRan Copper & Gold (FCX), Rio Tinto is entitled to 40% of additional material mined as a consequence of expansions and developments of the Grasberg facilities since 1998. Rio Tinto's share of production reflects actual production for the first nine months of 2007. (e) Rio Tinto's shareholding in Palabora varied during 2006 due to the progressive conversion of debentures into ordinary shares. (f) Rio Tinto's share of production includes 100% of the production from the Eastern Range mine. Under the terms of the joint venture agreement, Hamersley Iron manages the operation and is obliged to purchase all mine production from the joint venture. (g) Rio Tinto increased its shareholding in Rio Tinto Minerals - salt to 68.4% at the beginning of July 2007. (h) With effect from the second quarter of 2007 Rio Tinto is reporting uranium production as '000 lbs U3O8 rather than tonnes. Where Rio Tinto's beneficial interest in an operation has changed, as indicated above, the share of production has been calculated using the weighted average interest over the relevant periods.
