Rio Tinto - 3QOR 2006
Rio Tinto PLC
18 October 2006
Third quarter 2006 operations review
• Record iron ore production was achieved in the quarter as the Pilbara
expansion programme continued to deliver additional capacity.
• Higher grades and improved recovery rates at Kennecott Utah Copper
delivered record molybdenum production.
• Mined copper production was lower due to industrial action at Escondida and
refined copper production was down due to the commencement of a scheduled
smelter shutdown at Kennecott Utah Copper.
• Production at the Comalco Alumina Refinery was only slightly below the
record second quarter production, despite two planned major maintenance
shutdowns during the quarter.
• Titanium dioxide feedstock production continued to reflect the strength of
current customer demand and the expansion of the UGS plant.
• US coal production was at similar levels to the record production achieved
in the previous quarter.
• Production of hard coking coal continued to recover but year to date output
remained lower than 2005 reflecting customer demand.
• Diavik achieved record diamond production in the quarter.

IRON ORE AND IRON
Rio Tinto share of production (000 tonnes)
Q3 06 vs Q3 05 vs Q2 06 9 mths 06 vs 9 mths 05
Hamersley 25,221 +14% +9% 68,634 +8%
Robe River 7,570 +3% +5% 20,733 +2%
IOC (pellets and concentrate) 2,412 +5% -9% 6,923 +2%
Demand for iron ore remained strong in all markets during the quarter.
Expansion projects in the Pilbara remained largely on schedule and within
budget.
Hamersley and Robe River
Record quarterly iron ore production and sales in the Pilbara were achieved as
the ramp up of mine and port capacity expansions started to take effect.
Despite continued recovery from the impact of cyclone activity experienced
earlier in the year, Hamersley production was up nine per cent on the previous
quarter due to additional capacity coming on stream at the Yandicoogina mine and
the first full quarter of production from the newly commissioned Nammuldi mine.
Additional processing of low grade material at the West Angelas mine was the
main contributor to Robe River's three per cent increase in production compared
with the corresponding period last year.
HIsmelt
HIsmelt produced 25,800 tonnes of pig iron during the quarter as the plant
continued to ramp up to nameplate capacity of 800,000 tonnes a year. During the
quarter the plant achieved around 70 per cent availability, with peak production
at 65 per cent of nameplate capacity.
Iron Ore Company of Canada
Third quarter pellet and concentrate production was below the previous quarter
due to planned maintenance activities. Year to date pellet production was seven
per cent lower than the corresponding period last year as a result of the
extreme weather conditions experienced in the first quarter and a change in
product mix in favour of concentrate production. Concentrate production in the
first nine months of this year was up 60 per cent on the same period last year.
ENERGY
US thermal coal
Rio Tinto share of production (000 tonnes)
Q3 06 vs Q3 05 vs Q2 06 9 mths 06 vs 9 mths 05
Rio Tinto Energy America 31,302 +11% -1% 92,463 +7%
Third quarter production continued to reflect the recovery of rail capacity from
the 2005 maintenance campaign as well as the capacity expansions underway at the
Spring Creek and Antelope mines. The commissioning of a new dragline at Jacobs
Ranch earlier in the year also contributed to a new quarterly production record
at that mine.
Australian coal
Rio Tinto share of production (000 tonnes)
Q3 06 vs Q3 05 vs Q2 06 9 mths 06 vs 9 mths 05
Rio Tinto Coal Australia
Hard coking coal 1,732 -1% +13% 4,393 -22%
Other coal 7,665 -4% -5% 23,376 +0%
Production of hard coking coal was 13 per cent higher than the previous quarter
reflecting a partial recovery in customer demand. Year to date production was
22 per cent below the first nine months of last year reflecting softness in the
hard coking coal market.
Production from the Hunter Valley operations was aligned with the allocation set
under the Port Waratah Coal Services (PWCS) capacity balancing system. However
during the quarter, coal producers in the Hunter Valley voted not to continue
with the capacity balancing system in 2007. This will allow the Port of
Newcastle to operate on a take or pay basis and as a result, PWCS customers will
not have their coal handling requirements reduced to match the capacity of the
coal chain.
Uranium
Production at the Ranger mine recovered from the heavy rainfall and throughput
issues experienced in the second quarter of 2006, contributing to a 35 per cent
increase in uranium production in the quarter. Production at Rossing was in
line with the previous quarter.
INDUSTRIAL MINERALS
Rio Tinto share of production (000 tonnes)
Q3 06 vs Q3 05 vs Q2 06 9 mths 06 vs 9 mths 05
Borates 136 -3% -4% 408 -0%
Titanium dioxide feedstocks 338 +3% -4% 1,035 +6%
Borates production was at similar levels to the previous quarter and the
corresponding quarter of 2005. Year to date production was in line with the
corresponding period last year.
Titanium dioxide feedstock production in the first nine months of the year was
six per cent higher than 2005 reflecting continued strength in market demand.
The UGS expansion from 325,000 to 375,000 tonnes per annum is proceeding as
scheduled and is due for completion at the end of the year.
ALUMINIUM
Rio Tinto share of production (000 tonnes)
Q3 06 vs Q3 05 vs Q2 06 9 mths 06 vs 9 mths 05
Rio Tinto Aluminium
Bauxite 4,036 +7% +6% 11,695 +7%
Alumina 821 +13% -4% 2,452 +11%
Aluminium 215.2 -1% +4% 629.0 -1%
Third quarter bauxite production was seven per cent higher than the
corresponding period last year due to increased capacity resulting from the
NeWeipa project.
Production at the Comalco Alumina Refinery was only slightly below the record
production achieved in the second quarter, despite two planned major shutdowns
during the quarter. The Comalco Alumina Refinery is on schedule to reach
nameplate capacity by the end of the year as planned.
Production at Queensland Alumina and Eurallumina was in line with previous
quarters. During the quarter, Rio Tinto announced the sale of its 56.2 per cent
interest in the Eurallumina SpA refinery. The completion of the sale is
conditional on customary joint venture partner rights.
Production from all aluminium smelters was ahead of the previous quarter and,
with the exception of NZAS, the corresponding quarter last year. Aluminium
production from the Tiwai Point smelter was lower due to the gradual return of
some cells which were out of circuit as a result of power reductions caused by
low rainfall in the hydropower catchment area.
COPPER
Rio Tinto share of production (000 tonnes)

Mined gold (000 ozs) 8 -94% -58% 36 -91%
Kennecott Utah Copper
Mined production of copper, molybdenum and gold benefited from higher grades
compared with the corresponding period last year. Despite lower grades than in
the previous quarter, mined copper production was unchanged due to higher
throughput at the concentrator. Record molybdenum production in the third
quarter was due to higher grades and improved recovery rates.
Refined copper production was significantly lower than the same period last year
due to a major smelter shutdown which started in early September and is expected
to be completed shortly. Refined gold production was in line with the previous
quarter and higher than the comparative period last year due to a reduction in
inventories.
Escondida
Third quarter mined copper production was 23 per cent lower than the previous
quarter due to strike action over wage negotiations for most of August. The
strike action ended on 2 September.
Grasberg
Lower grades for copper, gold and silver as a result of mine sequencing led to
lower production for all three metals compared with the same quarter of 2005.
Rio Tinto's share of production is also affected by the metal strip, which
determines the allocation of volumes between the joint venture partners. The
structure of the agreement means that Rio Tinto's share of production is geared
to fluctuations in total production volumes. Rio Tinto's share of production
from the Grasberg mine is expected to be lower in 2006 and 2007 relative to
previous years, before increasing in 2008 and beyond.
Other copper operations
At Palabora total mill throughput, levels of concentrate smelted and anodes
produced were in line with the previous quarter. Increased production at
Northparkes reflected the continued mining of higher grade ore from the Lift 2
area.
DIAMONDS
Rio Tinto share of production (000 carats)
Q3 06 vs Q3 05 vs Q2 06 9 mths 06 vs 9 mths 05
Argyle 8,330 +39% +11% 21,052 -12%
Diavik 1,697 +30% +4% 4,402 +14%
Argyle
Increased carat production was achieved in the third quarter due to higher
grades. However continued variability in production levels is expected as the
mine approaches the end of the open-pit life and transitions to an underground
operation.
Diavik
Despite the challenges of the early closure of the ice road, Diavik achieved
record carat production in the quarter. Production was four per cent higher
than the previous quarter and 30 per cent higher than the same period last year,
largely as a result of improvements in throughput.
EXPLORATION AND EVALUATION
Pre-tax expenditure on exploration and evaluation charged to the profit and loss
account in the first nine months of 2006 was $175 million compared with $168
million in the first nine months of 2005. $38 million of this expenditure was
charged against business unit earnings.
Exploration drilling was sustained on copper targets in Chile, Argentina,
Kazakhstan, and the US. Exploration in Russia continued as part of the RioNor
Joint Venture. Diamond exploration remained focused on targets in Canada,
Botswana, Mauritania, India and Brazil. Iron ore exploration continued in
Western Australia and west Africa. Exploration for thermal and coking coal
continued in southern Africa, North America, South America and Mongolia. At
Chapudi coal in South Africa progress continued on drilling and securing land
tenements. Exploration for bauxite is ongoing in Brazil.
Brownfield exploration is underway at a number of Rio Tinto businesses,
including the Pilbara, Kennecott Utah Copper, the Freeport and Cortez Joint
Ventures, Greens Creek and Northparkes.
Evaluation work continued on a number of projects including Eagle (nickel/
copper, US), Resolution (copper/gold, US), Potasio Rio Colorado (potash,
Argentina), La Granja (copper, Peru) and Simandou (iron ore, Guinea). Rio Tinto
is monitoring the work by Northern Dynasty Minerals at the Pebble
copper-gold-molybdenum deposit in Alaska. Contract of Work negotiations continue
at La Sampala nickel in Indonesia.
CORPORATE ACTIVITY
During the quarter Rio Tinto's shares in Ashton Mining of Canada were taken up
by Stornoway Diamonds under its takeover bid for Ashton. In exchange for the
shares in Ashton, Rio Tinto will receive cash totaling approximately C$29.6
million and 25.6 million Stornoway common shares.
CAPITAL MANAGEMENT PROGRAMME
During the first nine months of 2006, the Group bought back $1,750 million of
Rio Tinto plc shares under the 2006/2007 $2.5 billion share buyback programme
announced on 2 February 2006. In addition, a special dividend of $1.5 billion
was paid on 6 April, bringing the total returned to shareholders to date under
the 2006/07 programme to $3,250 million.

RIO TINTO SHARE OF PRODUCTION (continued)
Production data notes
(a) Rio Tinto announced the sale of its 56.2% share in Eurallumina on 17
August 2006. The sale is conditional on customary joint venture partner rights
and the numbers above reflect a full quarter's production.
(b) Rio Tinto Coal Australia manages all the operations below; including the
mines which were previously reported separately under the Coal & Allied name.
(c) Rio Tinto Energy America was previously known as Kennecott Energy.
(d) 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.
(e) 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.
(f) During the second half of 2005, the conversion of debentures into
ordinary shares resulted in a dilution of Rio Tinto's shareholding in Palabora
from 49.2% to 47.2%. The conversions continued during the first nine months of
2006 and during the third quarter Rio Tinto also participated in the conversion
of debentures. The Rio Tinto shareholding on 30 September 2006 was 57.67%.
(g) Kelian ceased processing ore on 7 February 2005 and the final gold pour
was on 27 May 2005.
(h) On 30 November 2005, Rio Tinto sold its interest in Lihir Gold; it had
agreed in September 2005 to relinquish the management agreement for Lihir. The
production data are shown up to 30 September 2005, from which date the Rio Tinto
interest in Lihir was held as an investment rather than being equity accounted.
(i) 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.
(j) Rio Tinto sold its 19% interest in the Labrador Iron Ore Royalty
Income Fund on 23 March 2005. The Fund has a shareholding in Iron Ore Company of
Canada but this was not included in the calculation of tonnage attributable to
Rio Tinto.
(k) HIsmelt(R) commenced production during September 2005.
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. Rio Tinto percentage interest shown above is
at 30 September 2006.
