Qrtly Production Report -Pt.1

Rio Tinto PLC 24 October 2001 Rio Tinto Quarterly Production Report For the Quarter ending 30 September 2001 * Rio Tinto's major acquisitions completed in the last year contributed significantly to higher production in the third quarter of 2001. * Iron ore production was 19% higher in the third quarter of 2001 compared with the same period in 2000. Hamersley and Robe River both established new quarterly production records. Third quarter 2001 shipments for both Hamersley and Robe exceeded both first and second quarters of 2001. * Coal production was 7% higher than in the third quarter of 2000. In the US, production was 6% lower than in the third quarter of 2000 due to lower production at Jacobs Ranch, although year to date production was some 5% higher than in the same period of 2000. Australian coal production continues to be significantly higher following the acquisition of the Lemington and Peabody coal assets in the Hunter Valley. * Mined copper production was in line with the same period in 2000. Production at Escondida fell by 17% but this was offset by full quarterly production contributions from Alumbrera and Northparkes. * Gold production increased by 36% compared with the same quarter of 2000 primarily due to higher production at Freeport and the increased capacity acquired with North. * Aluminium production was 1% lower than in the same quarter of 2000 as hydro power constraints in New Zealand, caused by drought conditions, lowered Tiwai Point output. * Diamond production was 99% higher than in the same quarter of 2000 as production at Argyle returned to higher grade areas in the pit coupled with an increased share in ownership following the Ashton acquisition. * Titanium feedstock production was 5% higher and borates production some 12% lower than the same quarter of 2000.

(b) Comalco increased its holding in Queensland Alumina Limited from 30.3% to 38.6%, with effect from 31 August 2001. (c) During March 2001, Rio Tinto increased its stake in Coal & Allied from 70.88% to 72.71%. (d) Coal & Allied has purchased the Australian subsidiaries of the Peabody Group. Production data are shown from 29 January 2001 the effective date of acquisition. Effective on the same date, Coal & Allied acquired an additional 11.8% interest in the Warkworth mine from Ticor Limited. (e) Production from the Lemington mine, acquired by Coal & Allied with effect from 20 December 2000, is included with Hunter Valley Operations. (f) 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. (g) 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. (h) 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. (i) Rio Tinto's initial interests in the Grasberg mine and in the Atlantic Copper smelter were acquired in 1995 by virtue of an acquisition of shares in Freeport-McMoRan Copper & Gold (FCX). As a result of FCX share buy-backs, Rio Tinto's interest in FCX has changed and, as of 30 September 2001, Rio Tinto had,by virtue of its FCX shareholding, a 14.3% share in Grasberg and a 16.6% 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. (j) Rio Tinto increased its holding in Palabora from 46.5% to 48.6% during November 2000; it acquired a further 0.7% in July 2001. (k) On 10 November 2000, Rio Tinto acquired control of Ashton Mining and, as of 17 January 2001, owned 100%. As a result of this purchase, with effect from 10 November 2000, Rio Tinto's effective interest in Argyle Diamonds increased from 59.7% to 99.8%. Shown separately is Rio Tinto's share of production from Ashton's diamond interests apart from Argyle. (l) Effective 14 February 2000, Rio Tinto's interest in Lihir decreased from 17.15% to 16.3% following a merger under a scheme of arrangement with Niugini Mining. (m) Rio Tinto acquired 20.3% of the Labrador Iron Ore Royalty Income Fund during the first half of 2001. 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. (n)Rio Tinto completed the sale of its interest in Norzink on 17 April 2001. 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 of its interest over the relevant periods.

(b) Comalco increased its shareholding in Queensland Alumina Limited from 30.3% to 38.6% with effect from 31 August 2001. Weipa production was affected by limited equipment availability during the third quarter of 2001 and adjustments to meet changed contract commitments. Total alumina production in the third quarter of 2001 improved compared with the second quarter of 2001 with QAL returning to a more normal level of operation. Production restrictions and unscheduled maintenance at the two refineries resulted in lower production in the first nine months of 2001 compared with 2000. In the third quarter of 2001, aluminium production at Tiwai Point was adversely affected by hydro power constraints which were a result of drought conditions; production at Bell Bay and Boyne Island smelters increased compared with the first two quarters of 2001 due to higher cell availability. Aluminium sales in the third quarter were similar to the second quarter of 2001. Comalco continued to market some of its primary aluminium in the US through Metal Exchange Corporation.

(b) Coal & Allied purchased the Australian subsidiaries of the Peabody Group effective 29 January 2001. Effective on the same date Coal & Allied acquired an additional 11.8% interest in the Warkworth mine from Ticor Limited. (c) Hunter Valley Operations consist of the merged Howick and Hunter Valley mines, plus the Lemington mine acquired with effect from 20 December 2000. (d) Sales relate only to coal mined by the operations and exclude traded coal. Coal production for Hunter Valley Operations increased in the third quarter of 2001 compared with the second quarter of 2001 due to improved overburden removal levels and increasing washery availability as a result of moving to seven days a week. Coal production at the Moura mine in the third quarter of 2001 was affected by maintenance and geotechnical issues which have now been resolved. First quarter 2001 figures for Moura, Warkworth, Ravensworth East, Narama and Bengalla are taken from the date of acquisition and do not reflect a full quarter.

The product mix is customer dependent. Blair Athol production was higher for the first nine months of 2001 when compared with the same period of 2000 due to minimal disruption from mining through old underground workings. These workings restricted production in 2000. Sales have decreased in the third quarter of 2001 when compared with the second quarter of 2001 due to train derailments on the Goonyella line, combined with port and rail capacity restrictions. The third quarter production at Kestrel was the highest since the mine was acquired by Pacific Coal in 1999. A contributory factor was the increase in reliability of the longwall equipment. Tarong production and sales were down this quarter due to a planned unit stop for maintenance at Tarong Energy Corporation. When compared with the first nine months of 2000, total coal production for the first nine months of 2001 was 11% higher and total sales were 4% higher.

Third quarter 2001 production of all metals, compared with the second quarter, was lower largely due to lower ore grade and the suspension of the North concentrator operation. In the third quarter of 2001, production of molybdenum was lower than in the third quarter of 2000 primarily due to lower ore grade and recovery. Smelter copper anode output was lower in the third quarter of 2001 compared with both the third quarter of 2000 and the second quarter of 2001 primarily due to lower plant availability associated with the scheduled flash converter maintenance shutdown. In the third quarter of 2001, refined copper, gold and silver production was lower than the third quarter of 2000 principally due to lower anode production. Compared with the second quarter of 2001, refined copper and silver production was lower as a result of lower smelter availability.

Production data are shown from 11 August 2000, the effective date of the acquisition. (b) Rio Tinto's 80% share of material from the Joint Venture. Modified draw strategy, implemented in April 2001, improved underground copper grade compared with last year. Gold grades, during the first nine months of 2001, remained higher than in the corresponding period of 2000 as sourcing of mill feed from open cut pits was increased. Palabora Total production at the Palabora mine, smelter and refinery (Rio Tinto 49.3%(a)) in South Africa. (100% basis) Palabora mine Ore treated ('000 tonnes) 6,814 6,514 4,167 2,745 4,056 19,223 10,967 Average ore grade copper (%) 0.59 0.59 0.60 0.59 0.70 0.59 0.63 Copper concentrates produced ('000 tonnes) 101.6 80.9 51.9 42.6 72.8 277.8 167.2 Average concentrate grade copper (%) 32.0 32.8 31.0 31.0 35.0 32.6 32.7 Copper in concentrates ('000 tonnes) 32.6 26.5 16.1 13.2 25.5 90.5 54.8 Palabora smelter/refinery New concentrate smelted on site ('000 tonnes) 87.8 83.9 75.5 77.0 81.7 198.0 234.1 New copper anodes produced ('000 tonnes)(b) 27.7 30.3 25.8 19.7 22.9 59.9 68.3 Refined new copper produced ('000 tonnes) 26.3 29.2 25.6 18.9 20.1 58.5 64.7 By-products: Magnetite concentrate ('000 tonnes) 60 49 44 43 55 190 142 Uranium oxide (tonnes) 34 28 13 10 8 67 31 Baddeleyite (several grades) ('000 tonnes) 1.6 2.2 1.7 1.3 1.0 5.7 4.0 Refined nickel sulphate (tonnes) 46 82 74 59 38 181 171 Vermiculite Plant Vermiculite produced ('000 tonnes) 56.9 64.1 36.1 34.9 47.2 144.3 118.1 (a) Rio Tinto increased its holding in Palabora from 46.5% to 48.6% during the fourth quarter of 2000; it acquired a further 0.7% in July 2001. (b) Contained copper in anodes; anode production includes a small amount produced from purchased material. Copper production improved steadily during the third quarter of 2001 as the operational difficulties experienced during, and in the aftermath of the strike, were overcome. Ore supply was affected by low crusher and shovel availability. Reduced ore feed limited concentrate production. Smelter production improved during the quarter following high levels of equipment availability and increased converter operating hours. Refined copper production remained low for the quarter although this mainly reflects the restocking of the refinery following low utilisation after the strike. Low concentrator and refinery throughput affected magnetite, nickel sulphate and precious metal production. Uranium and baddeleyite production ceased during the quarter following closure of the heavy minerals plant in August. Vermiculite production increased due to improved mining conditions during the dry season. Production was affected by a 14 day planned plant shutdown for essential refurbishment.

AK1 and alluvial ore processed was in line with previous quarters. Increased AK1 carat production in the third quarter of 2001 reflects the return to higher-grade areas in the pit, in line with the progress made on the AK1 pit development. Ashton Mining Rio Tinto share of production from the Ashton Mining (Rio Tinto 100% (a)) diamond interests apart from Argyle. (Rio Tinto share) Ore processed ('000 tonnes) - 95 95 61 141 - 296 Diamonds recovered ('000 carats) - 37 15 7 13 - 35 (a) Production data are shown from 10 November 2000, the effective date of acquisition of Ashton Mining. Although ore throughput at the Merlin mine improved in the third quarter of 2001, compared with the two previous quarters which were affected by weather, production was below expectations due to process plant constraints associated with the clayey nature of the ore. Carat production reflected ore throughput.
