2 QOR 2006

Rio Tinto PLC
19 July 2006

Second quarter 2006 operations review

•  The Group's share of iron ore production was a record for the quarter,
   increasing by four per cent compared with the second quarter of 2005, and by 
   16 per cent compared with the previous quarter, as the expansion programme
   delivered additional capacity. The operations in Western Australia recovered
   from the severe weather conditions experienced during the first quarter,
   although the impact on iron ore production continued into the second quarter.

•  HIsmelt made its first shipment to customers in the US.

•  Mined copper production rose by two per cent compared with the
   previous quarter, and by nine per cent compared with the second quarter of 
   2005, in line with increased grades at Kennecott Utah Copper and higher 
   production at Escondida from the Norte pit.

•  Production from the Comalco Alumina Refinery increased by 25 per cent
   in the second quarter compared with the first quarter, with operating levels
   showing increasing stability and at times exceeding 90 per cent of original
   design capacity.

•  Titanium dioxide feedstock production was three per cent higher than
   the previous quarter, and eight per cent above the same quarter of 2005,
   reflecting the strength of current customer demand and the further expansion 
   of the Upgraded Slag (UGS) plant.

•  US coal production reached record levels for the quarter, increasing
   by seven per cent compared with the first quarter, and by ten per cent 
   compared with the second quarter of 2005. This was in line with the recovery 
   of rail capacity and the expansions of the Spring Creek and Antelope mines.

•  Australian thermal coal production rose by six per cent compared with
   the previous quarter consistent with the availability of port and rail 
   capacity. Australian hard coking coal production recovered from the first 
   quarter but was below the second quarter of 2005, reflecting lower customer 
   demand.

IRON ORE AND IRON

Rio Tinto share of production (000 tonnes)

                                            Q2 06      vs Q2 05      vs Q1 06       H1  06      vs H1 05
Hamersley                                  23,042           +1%          +13%       43,414           +5%
Robe River                                  7,178          +11%          +20%       13,163           +1%
IOC (pellets and concentrate)               2,641           +7%          +41%        4,513           +1%


Global iron ore demand remained strong in all markets during the quarter. During
May and June, Hamersley and Robe agreed a 19 per cent increase in the benchmark
price for their products, for the 2006 contract year. In June, the Iron Ore
Company of Canada agreed a 17.3 per cent increase in the price of its iron ore
concentrate and a 3.5 per cent decrease in the price of pellets.

Construction of the $1 billion Hope Downs iron ore project in Western Australia
(Rio Tinto share $685 million) began in April, following Western Australian
Government approval and the ratification of the Hope Downs Joint Venture.

Hamersley and Robe River

The effects of the very severe cyclone season experienced in the first quarter
continued into the second quarter at both Hamersley and Robe, albeit to a lesser
extent.

Notwithstanding this, Hamersley's second quarter production was 13 per cent
higher than the previous quarter and half year production was five per cent
higher than the corresponding period of 2005. This was due, in part, to the
commencement of production at the Nammuldi mine.

HIsmelt

HIsmelt made its first shipment of almost 40,000 tonnes of pig iron to the US in
June.

Iron Ore Company of Canada

Pellet and concentrate production increased by 41 per cent compared with the
first quarter, when extreme winter conditions were experienced. Concentrate
production levels were higher than the previous quarter and the corresponding
quarter of 2005.

ENERGY

US thermal coal

Rio Tinto share of production (000 tonnes)

Rio Tinto Energy America                   31,680          +10%           +7%       61,161           +5%

Production in 2006 has increased following the recovery of rail capacity from
the 2005 maintenance campaign. The Antelope mine set a new quarterly and half
year record with the expansion project continuing ahead of schedule. The $46
million expansion that is underway at the Spring Creek mine, which will raise
capacity from 12 to 16 million tonnes per annum, contributed to a new quarterly
production record.

Australian coal

Rio Tinto share of production (000 tonnes)

Rio Tinto Coal Australia
    Hard coking coal                        1,535          -21%          +36%        2,661          -31%
    Other coal                              8,093          +11%           +6%       15,711           +3%

Production of hard coking coal at Hail Creek reflected lower vessel
presentation. Production from the Hunter Valley operations was in line with the
allocation set under the Port Waratah Coal Services capacity balancing system,
contributing to a six per cent increase in thermal coal production during the
quarter.

Uranium

Second quarter uranium production declined by just over one third compared with
the first quarter, due to heavy rainfalls from a cyclone which prevented access
to high grade ore at the Ranger mine. Production was further impacted by a
reduction in the volume of ore treated due to difficulties experienced in
bringing the acid plant back to full production after a planned maintenance
shutdown.

INDUSTRIAL MINERALS

Rio Tinto share of production (000 tonnes)
                                            Q2 06      vs Q2 05      vs Q1 06       H1  06      vs H1 05

Second quarter borates production was nine per cent higher than the previous
quarter during which a number of maintenance shutdowns took place. Production in
the first half was consistent with the first six months of 2005.

Increased production of titanium dioxide feedstocks reflected the strength of
current demand and QIT's recently completed UGS expansion to 325,000 tonnes per
annum. The UGS expansion to 375,000 tonnes per annum is proceeding as scheduled.

ALUMINIUM

Rio Tinto share of production (000 tonnes)

Half year bauxite production was eight per cent higher than the comparative
period in 2005 due to the successful commissioning of the Andoom mine and
processing plant which form part of the NeWeipa project.

Second quarter production from the Comalco Alumina Refinery, at 322,000 tonnes,
was 25 per cent above the previous record quarter, with increased digestion pump
availability resulting in good production rates. There are two major shutdowns
planned for the Comalco Alumina Refinery for the third quarter. Production at
Queensland Alumina and Eurallumina was in line with the previous quarter.

Production at the aluminium smelters was slightly behind the first quarter of
2006, primarily due to cells being taken out of circuit at Tiwai Point, because
of low rainfall in the hydropower catchment area.

Kennecott Utah Copper

The optimisation of mine production in favour of molybdenum continued, although
lower grades during the quarter accounted for lower molybdenum production. Mined
copper production and gold contained in copper concentrate were higher compared
with the previous quarter and the same quarter in 2005, in line with higher
grades.

Refined copper and gold production was significantly higher in the second
quarter compared with the same period of 2005 due to strong operational
performance at the smelter and a 17 day planned maintenance shutdown in May
2005. The smelter will undergo a 45 day planned maintenance shutdown in
September and October 2006.

Escondida

Second quarter mined copper production was 12 per cent higher than the second
quarter of 2005 as a result of the commissioning of the Norte pit in September
2005 and the commencement of sulphide leaching in 2006.

Grasberg

Lower grades for copper, gold and silver as a result of mine sequencing led to
significantly lower production for all three metals compared with the same
quarter of 2005.

Other copper operations

Total mill throughput remained in line with the previous quarter at Palabora
with a significant improvement in daily ore production. Levels of concentrate
smelted and anodes produced increased from the first quarter following the
completion of the scheduled shutdown. Increased production at Northparkes
reflected the continued mining of higher grade ore from the Lift 2 area,
operational performance exceeded design capacity and mill recoveries averaged in
excess of 90 per cent.

DIAMONDS

Rio Tinto share of production (000 carats)

Argyle

Carat production recovered in the second quarter following adverse weather
conditions earlier in the year. Continuing variability in production levels can
be expected as the mine reaches the end of the open-pit life, and transitions to
an underground operation.

Diavik

Throughput at Diavik recovered from the previous quarter, in line with the
seasonally expected profile. Grades were higher than the previous quarter with a
relatively constant mix from higher grade A154S ore and lower grade A154N ore.

EXPLORATION AND EVALUATION

Pre-tax expenditure on exploration and evaluation charged to the profit and loss
account in the first half of 2006 was $113 million compared with $93 million in
the first half of 2005. $26 million of this expenditure was charged against
business unit earnings.

Exploration drilling was sustained on copper targets in Chile, Argentina, Mexico
and the US. Exploration in Russia ramps up 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 in
west Africa.  Exploration for thermal and coking coal opportunities continued in
southern Africa, North America, South America and Mongolia.

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
has taken a 9.9 per cent equity position in Northern Dynasty Minerals which
controls the Pebble copper-gold-molybdenum deposit in Alaska. Contract of Work
negotiations continue at La Sampala nickel in Indonesia.

CAPITAL MANAGEMENT PROGRAMME

During the first half of 2006, the Group bought back $1,027 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 $2,527 million.

RIO TINTO SHARE OF PRODUCTION (continued)

Production data notes

(a)     Rio Tinto Coal Australia manages all the operations below; including the
mines which were previously reported separately under the Coal & Allied name.

(b)     Rio Tinto Energy America was previously known as Kennecott Energy.

(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.

(e)     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 half of 2006 and
the Rio Tinto shareholding on 30 June 2006 was 46.4%.

(f)     Kelian ceased processing ore on 7 February 2005 and the final gold
pour was on 27 May 2005.

(g)     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.

(h)     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.

(i)     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.

(j)     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 June 2006.
