3Qtr Production Report-Pt 1

Rio Tinto PLC 25 October 2000 Part 1 Rio Tinto Quarterly Production Report For the Quarter ending 30 September 2000 Rio Tinto's production of most commodities in the third quarter of 2000 was up substantially on the previous quarter helped by the full ownership of Comalco Limited and the acquisition of North Limited midway through the quarter. *Iron ore production for the quarter was up 39% on the previous quarter. Much of this increase came from the first contribution from the iron ore assets of North but Hamersley Iron's production at 17.4 million tonnes was up 13% compared with the previous quarter. Hamersley Iron shipped a record 17.3 million tonnes during the quarter. *Aluminium production was up 20% on the previous quarter and was also up 20% for the year to date compared with the same period in 1999 reflecting full ownership of Comalco and continuing strong performance at all the smelters. *Copper mined production was 9% higher than the previous quarter, helped by higher production at Escondida, Chile and Grasberg, Indonesia. *Coal production was 11% higher than the previous quarter, mainly due to higher production in the US. However, coal production for the first nine months of 2000 was 7% lower than the same period in 1999. *Gold production increased by 13% compared with the previous quarter due to higher grades at Kennecott Utah Copper, US and higher production at Kelian, Indonesia. *Borate production increased by 19% in the quarter, primarily reflecting the timing of maintenance and resulting in a 3% increase year to date compared with 1999. Titanium dioxide feedstock production increased by 10% during the quarter after the reinstatement of full production capability following completion of repairs to the furnace at QIT, Canada which was damaged in 1999, although the year to date production is 7% lower than the same period in 1999.

As a result of FCX share buy-backs, Rio Tinto's interest in FCX has changed and, as of 30 September 2000, Rio Tinto had, by virtue of its FCX shareholding, a 13.8% share in Grasberg and a 16.1% share in Atlantic Copper. Under the Joint Venture agreement with FCX, Rio Tinto is entitled to 40% of additional material mined as a consequence of the expansion of the Grasberg facilities. The additional entitlement is shown separately in the above tables. (b) Rio Tinto's share of production from the assets owned by North Limited is shown with effect from 11 August 2000, the effective date of the acquisition. (c) Effective 14 February 2000, Rio Tinto's interest in Lihir decreased from 17.15% to 16.3% following a placement of shares by Lihir Gold. (d) Up until 31 December 1999, the above table included Rio Tinto's share of production from its one third interest in Minera S.A. This was sold at the end of 1999. (e) 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. (f) On 10 January 1999, Rio Tinto increased its beneficial interest in the Blair Athol mine from 57.2% to 71.2%. (g) Rio Tinto acquired Kestrel Coal, formerly Gordonstone, in February 1999 and production commenced in June 1999. (h) With effect from 1 July 1999, Coal & Allied purchased the Rio Tinto coal interests in New South Wales that were previously held under the Novacoal name. Coal & Allied also purchased Mitsubishi Development Pty Ltd's 40% interest in the Howick mine. The restructuring of Coal & Allied's shareholdings left Rio Tinto with a 70.9% interest. Rio Tinto's share of production for quarters prior to 1 July 1999 is reported in line with the pre-merger shareholdings. (i) Rio Tinto has a 50% share in Kaltim Prima and, under the terms of its Coal Agreement, the Indonesian Government is 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. (j) Rio Tinto disposed of its interest in Carbones del Cerrejon in early January 2000. (k) Rio Tinto progressively increased its interest in Comalco from 70.4% to 72.4% during the first half of 1999. During the first half of 2000, Rio Tinto offered to acquire all the shares in Comalco and now holds 100%. Rio Tinto's share of production has been calculated using the weighted average of Rio Tinto's interest over the relevant periods.

In the third quarter of 2000, production of all metals in concentrate exceeded the third quarter of 1999, primarily due to higher ore grade. Compared with the second quarter of 2000, gold and silver production was greater mainly due to higher ore grade, conversely, copper and molybdenum output was lower largely as a result of lower ore grade and harder ore. Smelter copper output was lower in the third quarter of 2000 compared with the third quarter of 1999 primarily due to acid plant availability. Compared with the second quarter of 2000, production was slightly higher. In the third quarter of 2000, refined gold production compared with the third quarter of 1999, was higher mainly due to higher ore grade. Refined silver in the third quarter of 2000 was lower than the third quarter of 1999 primarily due to lower smelter anode copper production and timing of production from intermediate products. Compared with the second quarter 2000, refined silver output was better largely due to timing of production from intermediate products.

(b) Net of smelter deductions. In the third quarter of 2000,production of copper and gold in concentrates increased compared with the second quarter of 2000 due largely to an increase in ore throughput and higher ore grades. Gold production in the third quarter was below that achieved in the corresponding period of 1999 due to significantly lower gold ore grades.

Contained gold and silver were also down. The decline in oxide ore processed in the first nine months of 2000 reflected a slow first quarter where buffer stocks or crushed ore on the pads exceeded leach requirements. The oxide plant continued to produce consistently at 140,000 tonnes per annum capacity. Somincor Total production at the Neves Corvo mine (Rio Tinto 49%) in Portugal.

High head-grades associated with the revised mining strategy have improved concentrate production well above 1999 levels. Operational problems in the converter and anode sections combined with the smelter shutdown during June reduced anode output and hence refined copper production. Nickel sulphate production for the year to date was higher reflecting the high electrolyte inventory level carried over from December 1999. Magnetite production was higher for the nine month period in order to meet market demand. The drop in baddeleyite feed from the Heavy Minerals Plant due to the revised copper pit mining strategy and lower feed grades received from Foskor had a negative effect on gross baddeleyite production during the third quarter. This flowed through to the other grades of baddeleyite. This situation is expected to continue for the rest of the year. Vermiculite production during the third quarter improved substantially, following the negative effects of excessive rain during the first and second quarters.

(b) Rio Tinto acquired Kestrel Coal, formerly Gordonstone, in February 1999 and production commenced in June 1999. (c) Semi-hard coking coal is a mixture of thermal coal and coking coal. The product mix is customer dependant. Year to date 2000 production at Blair Athol is below comparative 1999 levels due to problems associated with mining through areas that contain old underground workings. This has had a flow-on effect on sales. Kestrel continued to build up its production rate since recommencing operation in June 1999.

The restructuring of Coal & Allied's shareholding left Rio Tinto with a 70.9% interest. (b) Hunter Valley Operations consist of the now merged Howick and Hunter Valley mines. (c) Sales relate only to coal mined by the operation and exclude traded coal. Coal production for Hunter Valley Operations in the third quarter of 2000, when compared with the second quarter of 2000, was limited by major maintenance on the coal preparation plant and by industrial action. Coal production, year to date, was lower than in the comparable period of 1999 due to a dispute with a significant domestic customer. Coal production at Mount Thorley in the third quarter 2000 was higher compared than in the second quarter 2000, which was affected by industrial action, wet weather and a planned shutdown of the dragline for 28 days.
