2Q 2005 operations review

Rio Tinto PLC
20 July 2005

Second quarter 2005 operations review





•   Most operations continued to produce at, or near, capacity in response
    to strong demand.



•   Hamersley produced and shipped record volumes of iron ore in the second 
    quarter as commissioning of the major infrastructure expansion progressed.  
    Production of both copper and gold from the Grasberg mine was also
    significantly higher than in the comparative period of 2004 when the 
    focus was on recovery from the 2003 material slippage.



•   Mining at Kennecott Utah Copper favoured higher molybdenum grade ore to take 
    advantage of the strong market for that product.  First half molybdenum
    production was in excess of full year production for 2004.  The scheduled
    smelter maintenance shut down, which impacted refined copper and gold
    production, was completed as planned.



•   First half alumina production was 45 per cent higher than the first half 
    of 2004 due to the ramp-up of the new Comalco Alumina Refinery and continued 
    process stability at QAL and Eurallumina.  All the aluminium smelters
    continued to operate at, or close to, capacity.



•   Australian coal production remained constrained by port and rail capacity.  
    The approval of a queue management system at Dalrymple Bay resulted in 
    shorter vessel queues, but only towards the end of the period.



•   An agreement to form a joint venture to develop the Hope Downs iron ore 
    deposits in Western Australia was announced in July 2005.  The development
    of the project will further strengthen Rio Tinto's position as Australia's 
    prime supplier of iron ore.

Demand was strong from all markets throughout the first half of the year and
production was at record levels.  Brownfield mine expansions at Tom Price,
Marandoo and Nammuldi were announced in April 2005 to add to the extensive mine,
rail and port expansion, construction of which is now well advanced.  In July
2005 an agreement to form a joint venture with Hancock Prospecting for the
development of the Hope Downs project was announced.  This will further
strengthen Rio Tinto's position as the prime supplier of iron ore from
Australia.  The new HIsmelt (R) direct iron smelting plant entered its
commissioning phase in the second quarter of 2005.  First hot metal was produced
in mid-June.



Hamersley

Hamersley achieved record production and shipments in both the second quarter
and the first half of the year.  Commissioning of the major port and rail
infrastructure expansion has commenced and will continue progressively through
the second half of the year.



Robe River

First half production was a record although May shipments were affected by heavy
rain at Cape Lambert, and West Angelas production was affected by a planned two
week shutdown as part of the expansion of capacity to 25 million tonnes per
annum.



Iron Ore Company of Canada

Improved employee productivity under the new collective agreement and improved
plant availability resulted in record first half pellet production, nine per
cent above the first half of 2004.  Concentrate production increased due to mill
infrastructure upgrades.



ENERGY



US thermal coal

Rio Tinto share of production (000 tonnes)
                                          Q2 05       vs Q2 04       vs Q1 05          H1 05      vs H1 04
Kennecott Energy                         28,916            +0%            -1%         58,156           +3%



Second quarter production was marginally below the first quarter of the year as
shipments were disrupted by two train derailments on the main line in May and
ongoing railroad maintenance.  Increased railroad maintenance is expected to
continue through the summer, and possibly later into the year, which will
adversely affect Powder River Basin coal shipments.



Approval was given for the expansion of Antelope mine and development of the
West Antelope reserves which were recently purchased.  At a capital cost of
US$87 million, this will facilitate the optimisation of the current facilities
and enable production to be increased in line with market demand.



Australian coal

Rio Tinto share of production (000 tonnes)
                                         Q2 05       vs Q2 04       vs Q1 05          H1 05       vs H1 04
Rio Tinto Coal Australia
  Hard coking coal                       1,952            -7%            +3%          3,855           +17%
  Other coal                             7,298           -15%            -9%         15,290            -4%



Available port and rail capacity continued to constrain export shipments from
the Australian coal operations.  A queue management system was successfully
implemented at Dalrymple Bay from late April although it was only in the latter
part of the period that the vessel queue reduced significantly.



At the port of Newcastle, where a capacity balancing system has been in place
for over a year, June sales were affected by longer vessel queues due to
producers scheduling of vessels to meet second quarter shipment allocations.



Production volumes reflect both the effects of shipping constraints and the
normal variation in line with the mining sequence.



INDUSTRIAL MINERALS



Rio Tinto share of production (000 tonnes)
                                         Q2 05       vs Q2 04       vs Q1 05          H1 05       vs H1 04

As in the first quarter of the year, demand in end use markets continued to be
robust although Rio Tinto Iron & Titanium's iron and steel co-product markets
softened somewhat in the second quarter.  Titanium dioxide feedstock production
at QIT and RBM was similar to the first quarter but well above the first half of
2004.  QIT's Upgraded Slag (UGS) expansion continued to ramp up from 250,000
tonnes towards 325,000 tonnes in line with the commissioning schedule.
Production of borates returned to normal following unusually wet weather in the
first quarter.



ALUMINIUM



Rio Tinto share of production (000 tonnes)

Bauxite production continued to increase following the completion of the NeWeipa
mine expansion and the ramp-up of the new Comalco Alumina Refinery which
produced 228,000 tonnes in the quarter.



Good process stability at QAL resulted in quarterly production of over one
million tonnes for the first time.  Production from Eurallumina was in line with
the first quarter but marginally below the record levels achieved in the second
half of 2004.



All smelters continued to produce at, or close to, capacity.

Kennecott Utah Copper

In order to take advantage of the current strong market for molybdenum, mine
production was optimised to maximise molybdenum production and so copper
concentrate production was lower than in the previous quarters.  Both gold and
molybdenum grades were significantly above the first half of 2004.  Molybdenum
production also increased as a result of modifications to the molybdenum circuit
at the concentrator.  An expansion of the molybdenum plant, which is designed to
increase recoveries, was completed in June 2005.



The May smelter maintenance shutdown proceeded as planned with no major issues.



Escondida

Mined copper production was below the second quarter of 2004, but above the
first quarter of 2005 reflecting variations in grade due to mine sequencing.
Mill throughput continued to be optimised, resulting in improved daily
production rates.



Grasberg

Production of both copper and gold was below the first quarter of 2005 as a
result of scheduled mine sequencing.  Harder ore adversely affected mill rates.
Production in the first half of 2005 was significantly above the first half of
2004 when resources were dedicated to recovery from the 2003 material slippage.
Rio Tinto's share of production has been calculated using the adjusted joint
venture allocation, known as the metal strip, which was described in the 2004
fourth quarter operations review.

Other

Production at Palabora reached nameplate capacity in the quarter, averaging in
excess of 30ktpd for both May and June.  Nameplate capacity was also achieved at
Northparkes in June.


DIAMONDS

Diavik                                      1,509           +11%           +44%         2,558           +12%



Argyle

Production at Argyle continued at normal levels in the second quarter of 2005,
substantially above the comparable period of 2004, when lower grade ore was
processed as a result of tight mining conditions.



Diavik

Production from Diavik was a quarterly record with higher volumes of ore
processed offsetting the effects of lower grades.



EXPLORATION AND EVALUATION



Pre-tax expenditure on exploration and evaluation charged to the profit and loss
account in the first half of 2005 was $93 million compared with $72 million in
the first half of 2004.  Following the presentational changes announced in May
2005, some of this expenditure will be charged against business unit earnings.



Exploration drilling continued on copper targets in Chile, Turkey, Mexico and in
the US.  Diamond exploration continued in Canada, Botswana, Mauritania, India
and Brazil.  Iron ore exploration continued in the Hamersley Basin (Western
Australia) and in west Africa.  Exploration for thermal and coking coal
opportunities continued in southern Africa, Australia and Canada.  At La Sampala
(nickel, Indonesia), scoping studies are underway.



Brownfield exploration is under way at a number of Rio Tinto businesses, with
notable efforts to expand resources being made in the Pilbara, at KUC, on the
Freeport and Cortez joint ventures, at Greens Creek, and at Northparkes.



Evaluation work continued at Eagle (nickel/copper, US), Sari Gunay (gold, Iran),
Resolution (copper/gold, US), Potasio Rio Colorado (potash, Argentina) and
Simandou (iron ore, Guinea).  Reflecting the positive progress so far in its
evaluation and pilot work at Potasio Rio Colorado, Rio Tinto exercised its
option over the Potasio Rio Colorado project in July 2005 to take full ownership
of the project.

Production data notes



(a)     Comalco Alumina Refinery started production in the fourth quarter of
2004.

(b)     Rio Tinto completed the sale of its 4.0% interest in the Boke mine on 25
June 2004. Production data are shown up to the date of sale.

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

(d)     Rio Tinto reduced its shareholding in Hail Creek from 92.0% to 82.0% on
15 November 2004.

(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)       From mid 1995 until 30 March 2004, Rio Tinto held 23.93 million shares
of Freeport-McMoRan-Copper & Gold (FCX) common stock from which it derived a
share of production. This interest was sold to FCX on 30 March 2004. Also,
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 and developments of the Grasberg facilities since
1998.

(g)     Rio Tinto completed the sale of its 49% interest in Somincor on 18 June
2004. Production data are shown up to the date of sale.

(h)     Ore mining and processing at Murowa commenced during the third quarter
of 2004.

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

(j)       Rio Tinto's share of gold production includes an estimate of the
production from the Lihir gold mine for the second quarter of 2005. The actual
second quarter production, which may be different from the figure in this
report, will be announced by Lihir Gold on 28 July 2005. The estimate in this
report is based on the indicative second quarter 2005 production as previously
disclosed in the Lihir Gold Limited First Quarter Mining and Exploration Report
(published 26 April 2005).

(k)     Rio Tinto sold its interest in Morro do Ouro on the 31 December 2004.
Production data are shown up to the date of sale.

(l)       As a result of the corporate restructuring completed on 8 July 2004,
Rio Tinto has ceased to be an ordinary shareholder in the renamed RioZim but
will retain a reduced cash participation in its gold and nickel assets for a
period of ten years.

(m)   Rio Tinto's share of production includes 100% of the production from the
Eastern Range mine, which commenced production in March 2004. 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.

(n)     Rio Tinto sold its 19% of the Labrador Iron Ore Royalty Income Fund on
23 March 2005. 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.

(o)     Rio Tinto completed the sale of its 100% interest in the Zinkgruvan mine
on 2 June 2004. Production data are shown up to the date of sale.



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 2005.
