Rio Tinto 4QPR 2003

Rio Tinto PLC 21 January 2004 Fourth Quarter 2003 Production Report • Iron ore - Demand for all products remained strong. Hamersley achieved record production and shipments in the fourth quarter bringing full year shipments to 74.3 million tonnes. West Angelas ramp-up continued ahead of schedule and reached an annualised rate of 18 million tonnes in December. • Copper - mined copper was 17 per cent below the previous quarter and 25 per cent below the final quarter of 2002 largely due to the material slippage at the Grasberg mine. • Diamonds - the ramp-up process at Diavik continued. Production was lower than in the preceding quarter due to the processing of stockpiled lower grade ore and ore from the top of the A154N pipe. Production from Argyle was also lower, reflecting lower grade material mined in line with the mining schedules. • Australian and Indonesian coal - excluding the effect of the new Hail Creek coking coal mine, Australian coal production was in line with the previous quarter but five per cent below the fourth quarter of 2002 reflecting market conditions. Port and rail congestion in New South Wales remain an issue. • US Coal - production was similar to the fourth quarter of 2002. Higher volumes from both Antelope and Jacobs Ranch were offset by lower production from Cordero Rojo where resources continue to be diverted to managing the high wall and spoil piles. • Aluminium - production was three per cent above the third quarter as Tiwai Point returned to full production following power shortages earlier in the year and improved process stability at the Boyne Island smelter. • Gold - mined gold production was 26 per cent below the preceding quarter due to the slippage at Grasberg. In addition, the disposal of Peak and Alumbrera plus lower by-product grades at Kennecott Utah Copper resulted in mined gold volumes 37 per cent below the fourth quarter of 2002. • Industrial minerals - production of titanium dioxide feedstock was eight per cent below the fourth quarter of 2002. The seasonal pick up in the second half has not been seen to the extent that would normally be expected. Borates production was in line with 2002 but lower than the previous quarter due to a planned shutdown.

(d) In December 2003 Pacific Coal was renamed Rio Tinto Coal Australia. (e) Rio Tinto had a 50% share in Kaltim Prima and, under the terms of its Coal Agreement, the Indonesian Government was entitled to a 13.5% share of Kaltim Prima's production. Rio Tinto's share of production shown is before deduction of the Government share. Rio Tinto completed the sale of its interest in PT Kaltim Prima Coal on 10 October 2003. Production data are shown up to the date of sale. (f) Kennecott Energy has a partnership interest in the Colowyo mine but, as it is responsible under a management agreement for the operation of the mine, all of Colowyo's output is included in Rio Tinto's share of production. (g) Rio Tinto completed the sale of its 25% interest in Minera Alumbrera together with its wholly owned Peak Gold Mine on 17 March 2003. Production data are shown up to the date of sale. (h) Through its interest in Freeport-McMoRan-Copper & Gold (FCX), Rio Tinto had, as of 31 December 2003, an 11.8% share in the Grasberg mine and a 13.1% share in Atlantic Copper. Rio Tinto's holding in FCX reduced from 14.0% to 13.1% during the fourth quarter of 2003 due to the conversion of convertible preferred stock into common stock. Through a joint venture agreement with FCX, Rio Tinto is entitled, as shown separately in the above tables, to 40% of additional material mined as a consequence of expansions of the Grasberg facilities since 1998. (i) Rio Tinto's interest in the Argyle Diamond mine increased from 99.8% to 100% on 29 April 2002, following the purchase of the outstanding units in the Western Australian Diamond Trust. (j) Following a placement of shares on the 13 November 2003 Rio Tinto's interest in Lihir moved from 16.3% to 14.5%. (k) Rio Tinto owns 20.3% of the Labrador Iron Ore Royalty Income Fund. The Fund has a shareholding in Iron Ore Company of Canada but this has not been included in the calculation of tonnage attributable to Rio Tinto. (l) Rio Tinto increased its shareholding in Iron Ore Company of Canada from 56.1% to 58.7% on 20 December 2002. (m) Rio Tinto completed the sale of its 100 % interest in the Fortaleza nickel mine on 16 January 2004.

(b) Net of smelter deductions. In the fourth quarter of 2003, copper and gold production and sales decreased compared with the third quarter of 2003 and the fourth quarter of 2002 because of a decrease in ore treated; this was due to the impact on mining operations at the Grasberg open pit mine of a material slippage on 9 October 2003 and a debris flow in the same section of the open pit on 12 December 2003. For the full year 2003, copper production and sales were lower compared with 2002 because of lower copper ore grades and the impact of the material slippage. Gold production and sales for full year 2003 were higher compared with 2002 because the higher gold ore grades more than offset the impact of the material slippage. Near-term mine sequencing operations are being directed to accelerating removal of waste material from the south wall, where the material slippage occurred, to ensure the restoration of safe access to the higher grades areas.

By-product grades for silver and molybdenum improved in the fourth quarter of 2003 but full year grades for by-products are still significantly lower than in 2002. As previously announced, lower by-product grades are expected to continue until 2005. High arsenic levels have adversely affected recovery of molybdenum. Higher gold recovery increased gold output in the fourth quarter, the copper grade decreased due to mining sequence. Anode production in both the first and second quarters of 2003 was affected by the failure of the final absorption tower of the acid plant in March 2003, which interrupted smelter production for three weeks. Refined copper production in the fourth quarter of 2003 was lower than in the third quarter due to delays in scrap remelting and ramp-up of a new production schedule.

Production from the underground mine improved by 20% to an average of 21,983 tonnes of ore per day during the fourth quarter of 2003, compared with an average of 18,355 tonnes of ore per day in the third quarter. During the fourth quarter, a production rate of 31,187 tonnes in one day, and a weekly rate of 26,528 tonnes per day were achieved. Tonnage of ore treated during the fourth quarter of 2003 was in line with the underground output. The ramp scavanging was completed in November. Copper in concentrate increased with the improved head grades and recoveries. Total concentrate smelted comprised run-of-mine production, smelter secondaries and imported concentrate. Anode stocks available to the tankhouse increased to an acceptable level. Refurbishment of the batch plant resulted in increased nickel production. Vermiculite production was stable and the reconfigured plant continues to meet market demand. Production during the third and fourth quarters of 2003 was reduced in order to lower supply chain inventory levels.

The seaborne market for both pellets and concentrates remains tight on the back of strong growth in Chinese iron ore imports. Pellet shipments for both the fourth quarter of 2003 and for the full year were significantly higher than in 2002, driven by stronger seaborne demand and higher production. Concentrate demand was also strong with fourth quarter 2003 shipments higher than in the fourth quarter of 2002; full year 2003 shipments were lower than in 2002 due to concentrate diversion to pellet production and production constraints in the first quarter of 2003. All excess saleable product inventory was drawn down. Saleable concentrate production was higher in the fourth quarter of 2003 compared with the fourth quarter of 2002, driven by higher crude ore production resulting from improved mining and automatic train operations, better recovery and on-going concentrator improvements. Pellet production in the fourth quarter of 2003 was also higher than in the fourth quarter of 2002, mainly due to productivity improvements and no furnace shutdowns. Total pellet production was higher in 2003 than 2002 due to operational improvements and a very much shorter plant maintenance shutdown (three days versus five weeks).

Sales were lower than in the previous quarter due to deferral of some shipments into 2004 as a result of congestion at receiving ports. Production at West Angelas reached a rate of 18 million tonnes per year in December, and the mine is on schedule to reach its design rate of 20 million tonnes per year by the end of the first quarter of 2004. Sales growth for West Angelas product focused primarily on Japan, where all customers exercised their tonnage options, and on further penetration of the Chinese market.
