First quarter 2008 operations review

16 April 2008

Commenting on the first quarter’s production results, chief executive Tom Albanese said: “Our expansion drive continues to pay off with a record-breaking first quarter for the iron ore and aluminium product groups. Markets remain very strong and the prices of many of our products are at record highs, bearing out our view that the US slowdown will have little effect on global metal and mineral supply and demand balances.

“The integration of the Alcan acquisition is going well, and our investment assumptions for this business are already being exceeded. This year we expect to invest at record levels across the group in bringing new production onstream, so we can continue to benefit from economies undergoing rapid, metals intensive phases of development.”

• Record first quarter global production of iron ore, up 16 per cent on the first quarter of 2007.

• Record first quarter iron ore production of 43 million tonnes in the Pilbara, Western Australia, up 15 per cent (100 per cent basis) compared with the first quarter of 2007 as the iron ore operations deliver their rapid expansion programme.

• Strong contribution from Rio Tinto Alcan in the quarter, with a significant uplift in production compared to the first quarter of 2007. Bauxite increased by 106 per cent, alumina by 236 per cent and aluminium by 386 per cent, following a good performance from the Canadian smelters.

• On a proforma basis the respective increases for bauxite, alumina and aluminium were 20 per cent, ten per cent and two per cent.

• Mined copper production declined by six per cent compared with the first quarter of 2007, primarily reflecting lower grades at Kennecott Utah Copper and Northparkes.

• Australian thermal and coking coal production was affected by heavy rains, notably in Queensland where the coal industry generally suffered production and logistics disruption.

• Uranium production was 20 per cent higher than the 2007 comparative period.

• During the quarter Rio Tinto reached agreement on the first two sales under its planned programme to divest around $10 billion of assets in 2008. The sale of the Greens Creek silver, lead and zinc mine in Alaska for $750 million was announced and the sale of the Cortez gold mine in Nevada was completed for $1.695 billion. In addition, Rio Tinto will benefit from a deferred bonus payment in the event of a significant discovery of additional reserves and resources at the Cortez gold mine and will also retain a contingent royalty interest in future production. Funds from these sales will be used to pay down part of the debt raised to finance the Alcan acquisition.

IRON ORE

Rio Tinto share of production (000 tonnes)

	Q1 08		vs Q1 07			vs Q4 07
Hamersley		27,016		+13	%		-6	%
Hope Downs		538		—			+1587	%
Robe River		7,189		+11	%		-5	%
IOC (pellets and concentrate)		2,119		+50	%		-6	%

Conditions in the iron ore market remain extremely tight with demand continuing to grow strongly. Rio Tinto continued to negotiate with customers to establish the 2008 iron ore benchmark prices and obtain a freight premium, reflecting its proximity to major customers in Asia.

During the first quarter Rio Tinto was actively selling iron ore into the spot market, as foreshadowed in its announcement of 18 December 2007.

Production and rail tonnages both increased steadily during the quarter, helped by infrastructure debottlenecking and associated scheduling. Expanded rail yard capacity and the introduction of 40 new generation locos and new rolling stock will deliver increasing benefits during the year.

Expansion projects continued to make strong progress, with the capacity upgrade of the Cape Lambert port from 55 million tonnes to 80 million tonnes per annum proceeding on track, despite challenging conditions from tropical cyclones. The feasibility study into increasing annual capacity in the Pilbara to 320 million tonnes is advancing according to plan.

Hamersley, Hope Downs and Robe River

Production from the Pilbara operations was severely affected by cyclonic activity during the quarter. In addition, a serious failure of gas supply in January led to immediate power shortages throughout Western Australia, which curtailed production and rail operations for several days. Despite these adverse conditions, record first quarter production and sales were achieved. Production for the quarter would have been in line with the fourth quarter 2007, but for these conditions.

Hamersley’s record first quarter production was up 13 per cent on the corresponding quarter of 2007, following the ramp up of the Yandicoogina capacity expansion to 52 million tonnes per annum, and the brownfield expansions at Nammuldi and Tom Price in the West Pilbara.

The Hope Downs mine produced over one million tonnes during the quarter (on a 100 per cent basis) as it started to ramp up towards its 30 million tonnes per annum capacity by early 2009.

Robe River first quarter production was 11 per cent up on the previous corresponding period, reflecting improved production at Mesa J and West Angelas.

HIsmelt

HIsmelt has recorded limited production so far this year (18,073 tonnes) due to downtime for required maintenance. The opportunity to conduct trials has yielded strong signs that benefits from improvements will be realised, particularly to increase time in operation.

Strong interest in the HIsmelt technology has been sustained and licence negotiations with several steelmakers are progressing.

Iron Ore Company of Canada

Strong production of pellets and concentrates at the Iron Ore Company of Canada reflected record mine performance for a first quarter and debottlenecking efforts at the plant, as well as the absence of labour stoppages in 2007.

In March, Rio Tinto approved a US$475 million project to increase the Iron Ore Company of Canada’s annual production of concentrate to 22 million tonnes. The investment is the first phase of an expansion programme that may see production increase 50 per cent by 2011.

¹ Includes Alcan data from 1 January 2007.

² Excludes Vlissingen smelter (Netherlands,) which was divested in the first half of 2007.

Production records were set across the board in the Aluminium product group. First quarter production of bauxite, alumina and aluminium increased sharply compared with the same quarter of 2007 following the Alcan acquisition. Rio Tinto acquired the operating assets of Alcan with effect from 24 October 2007 and its production is included from that date. Proforma Rio Tinto Alcan production data for 2007 was published on 12 March 2008 and can be found on the Rio Tinto website at www.riotinto.com/media/5157_7363.asp

Bauxite

First quarter bauxite production was 106 per cent higher than the first quarter of 2007 and 20 per cent higher on a proforma basis. First quarter bauxite production at Weipa was 17 per cent above the same quarter of 2007, reflecting increased capacity following the commissioning of the second shiploader.

Alumina

First quarter alumina production was 236 per cent higher than the first quarter of 2007 and ten per cent higher on a proforma basis. The Yarwun alumina refinery operated consistently at its rated capacity of 1.4 million tonnes per annum, increasing production by 17 per cent when compared with the first quarter of 2007 when maintenance shutdowns occurred.

Cont.../

Continues Page 4 of 22

Expansion work on the Yarwun alumina refinery is progressing on budget and on track for its first shipment of alumina in the second half of 2010. The US$1.8 billion project, announced in July 2007, will more than double annual production of the refinery, taking output from 1.4 million tonnes to 3.4 million tonnes by 2011.

Construction of the 1.8 million tonne per annum expansion of the Gove refinery is nearing completion. Production during the first quarter of 2008 reflected stabilisation of the newly commissioned plant. Full capacity is anticipated to be achieved during 2009.

Aluminium

First quarter aluminium production was 386 per cent higher than the first quarter of 2007 and two per cent higher on a like for like basis. All the Rio Tinto Alcan smelters operated well throughout the quarter with the Canadian smelters raising production by four per cent compared with the proforma first quarter 2007 levels.

Kennecott Utah Copper

With the exception of molybdenum, metals’ head grades for the first quarter of 2008 were lower than those of the fourth quarter of 2007 and all metal head grades were lower than the first quarter of 2007. In addition, the processing of harder ore decreased throughput and increased maintenance at the concentrator.

Grades at Bingham Canyon are expected to remain relatively low during the first half of 2008 but are anticipated to return to more normal levels during the second half.

Production decreases at the smelter and refinery, from 2007 to 2008, are attributable to lower head grades and concentrate production, resulting in the depletion of concentrate inventory in late 2007. A 26 day refinery shutdown is scheduled for July 2008 and an 11 day smelter maintenance shutdown is scheduled for August 2008.

Escondida

Mined copper for the quarter improved by five per cent compared with the corresponding period of 2007, attributable to higher copper grades for the leachate material. Refined copper production in the first quarter of 2008 was 21 per cent lower than the prior year due to low oxide leach production.

Grasberg

Lower copper and gold grades were a major factor in lowering Rio Tinto’s share of copper production and reducing its share of gold production to nil in the first quarter of 2008, compared with the fourth quarter of 2007.

Cont.../

Continues Page 5 of 22

Mining is expected to continue in a relatively low-grade section of the Grasberg open pit in the first half of 2008 and a higher-grade section in the second half of 2008. Gold and silver volumes for 2008 are expected to be below the metal strip in 2008.

Other operations

Lower copper and gold production at Northparkes was due to the treatment of lower grade open cut stockpile material. Grade is expected to increase as the underground production from E26 Lift 2 North ramps up to full production, displacing the lower grade open cut material. Northparkes production for 2008 is expected to be more than 40 per cent below 2007.

DIAMONDS

Rio Tinto share of production (000 carats)

	Q1 08		vs Q1 07			vs Q4 07
Argyle		2,172		-37	%		-64	%
Diavik		1,071		-31	%		-39	%

Production at Argyle in the first quarter of 2008 was adversely affected by wet weather and a slip in the main pit access ramp that together restricted access to high grade ore zones. Pit access has been re-established and production is expected to improve as the wet season comes to an end. Variability in feed grades and production rates will continue as the open-pit approaches the end of its life and the mine transitions to an underground operation.

At Diavik, the quantities of ore processed and carats recovered in the first quarter of 2008 were 31 per cent lower than 2007. Extreme cold temperatures experienced between January and the first half of March negatively impacted equipment reliability resulting in lower ore recovered and processed. A decrease in grade which commenced in the fourth quarter of 2007 continued throughout the first quarter of 2008.

ENERGY

US thermal coal

Rio Tinto share of production (000 tonnes)

	Q1 08		vs Q1 07	vs Q4 07
Rio Tinto Energy America		30,632	+1%	-8%

First quarter production was lower than the preceding quarter, but rose slightly above the same quarter of 2007, as expansion projects at the Spring Creek and Antelope mines neared completion, offsetting lower production at Jacobs Ranch and Colowyo.

Australian coal

Rio Tinto share of production (000 tonnes)

Creek. Shipping opportunities were maximised at Blair Athol, which was not directly affected by the Queensland floods, with an eight per cent increase in production. Overall, the Rio Tinto coal operations in Queensland were able to maximise opportunities from the recent floods by buying and swapping rail and port allotments from other, worse impacted producers.

In New South Wales, reduced port throughput from coal chain infrastructure limitations continued to restrict output from Rio Tinto subsidiary Coal & Allied’s mines.

An investment programme by the owners and operators of the coal ports at Newcastle and Dalrymple Bay on the eastern seaboard of Australia is expected to increase capacity in the second half of 2008 and into 2009.

Rio Tinto sold its 100 per cent share in the Tarong Coal mine in Queensland with an effective date of 31 January 2008 and production data are shown up to that date.

Uranium

Rio Tinto share of production (000 lbs)

	Q1 08		vs Q1 07			vs Q4 07
Energy Resources of Australia		2,011		+33	%		-12	%
Rössing		1,335		+3	%		+10	%

First quarter 2008 production at ERA’s Ranger mine was 33 per cent higher than the comparative quarter of 2007 when exceptionally high rainfall was experienced. This rainfall event also impacted 2007 throughput, and ERA entered the 2008 wet season with lower than normal high grade stockpiles. This gave rise to a 12 per cent reduction in production in the first quarter of 2008 compared with the fourth quarter of 2007.

Higher grades at Rössing led to a three per cent improvement in production in the first quarter of 2008 compared with the same quarter of 2007.

MINERALS

Rio Tinto share of production (000 tonnes)

	Q1 08		vs Q1 07			vs Q4 07
Borates		153		+18	%		+1	%
Titanium dioxide feedstocks		356		+1	%		-7	%

First quarter borates production rose by 18 percent compared with the same quarter of 2007, driven by strong demand in Asia Pacific and Europe.

EXPLORATION AND EVALUATION

Pre-tax expenditure on exploration and evaluation charged to the profit and loss account in the first quarter of 2008 was $159 million compared with $72 million in same period of 2007.

Pre-feasibility or feasibility work progressed on a number of important projects including Resolution (copper/gold, US), La Granja (copper, Peru), Eagle (nickel/copper, US), Potasio Rio Colorado (potash, Argentina), Simandou (iron ore, Guinea) and several Pilbara iron ore deposits.

Production data notes

(a)	Rio Tinto acquired the operating assets of Alcan with effect from 24 October 2007; production is shown as from that date. The Rio Tinto assets and the Alcan assets have been combined under the Rio Tinto Alcan name.
(b)	Rio Tinto held a 38.6% share in QAL until 24 October 2007; this increased to 80.0% following the Alcan acquisition
(c)	Following a review of the basis for reporting aluminium smelter production tonnes, the data reported now reflects hot metal production rather than saleable product tonnes.
(d)	Rio Tinto Alcan has an 80% interest in the Awaso mine but purchases the additional 20% of production
(e)	Rio Tinto has a 22.9% shareholding in the Sangaredi mine but receives 45% of production under the partnership agreement.
(f)	Includes beneficiated and calcined bauxite production.
(g)	Rio Tinto sold its 100% share in Tarong with an effective date of 31 January 2008 and production data are shown up to that date.
(h)	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.
(i)	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. Rio Tinto’s share of production reflects actual production for the first quarter of 2008.
(j)	In February 2008 Rio Tinto reached agreement for the sale of Greens Creek and on 5 March 2008 the Group completed the sale of its interest in the Cortez joint venture to its partner. Cortez production data are shown up to that date.
(k)	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.
(l)	Hope Downs started production in the fourth quarter of 2007
(m)	Rio Tinto increased its shareholding in Rio Tinto Minerals — salt to 68.4% at the beginning of July 2007.

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 31 March 2008.
