Rio Tinto to place up to 15 million tonnes of iron ore into the
spot market in 2008

18 December 2007

Rio Tinto has announced plans to place up to 15 million tonnes of iron ore into the spot
market in 2008.

Rio Tinto announced at its Investor Seminar on 26 November 2007 that it is planning
substantial expansions of capacity over the next decade in its Western Australia Pilbara
operations. This will allow the Group to place substantially more tonnage on to the
higher-priced spot market while continuing to meet longer-term contractual commitments.
Rio Tinto has been active in the spot market during 2007 and in December sold one
million tonnes at US$190 per tonne. A similar volume has been sold for January shipment
at an average price of US$187 per tonne. This compares with the current equivalent
benchmark price of US$85 per tonne (FY2007 FOB benchmark plus spot freight).

“The iron ore market is changing”, said Tom Albanese, chief executive of Rio Tinto.
“Customers are demanding more transparency in pricing and more tonnes, faster than
ever before. Our industry-leading growth pipeline in iron ore puts us in a strong position
to benefit from stronger prices, now and in the future.”

Sam Walsh, Rio Tinto’s chief executive Iron Ore, said, “The bulk of Rio Tinto’s Pilbara
capacity is committed under long term contracts and Rio Tinto will continue to honour
these contracts. At the same time the gap between the benchmark and spot prices is
huge and we intend to continue to take advantage of those higher prices”.

Mr Walsh said the iron ore market was extremely tight. “We produce more tonnes at
lower cost, from locations closest to the growth iron ore markets. We believe in
competitive and transparent pricing, and our production expansion plans give us the
capacity to supply all of our markets and allow us to agree prices for all durations.”
This announcement follows the 26 November 2007 Investor Seminar outlining Rio Tinto’s
conceptual pathway to iron ore production of more than 600 million tonnes per year,
including 420 million tonnes a year from the Pilbara.

At that time Rio Tinto also announced a US$2.4 billion commitment to develop the Mesa
A and Brockman 4 iron ore deposits in the Pilbara, as well as outlining plans to increase
the potential capacity of its Simandou iron ore project in Guinea (West Africa) to 170
million tonnes per year.

The existing Pilbara rail and port infrastructure secures Rio Tinto’s position as the premier
Australian iron ore supplier, allowing it to reap maximum benefit from a strong pricing
outlook, Mr Walsh said. “We own and operate three ports in two locations, and we have
the capability to expand these facilities well beyond the existing levels.”

Notes to editors:
Rio Tinto believes that efficient short, medium and long term contracts need to
exist in the iron ore industry. At its Investor Seminar on 26 November 2007, Rio Tinto
outlined its intention to operate a mix of three pricing approaches:

. Short-term spot sales;

. Hybrid contracts – which are based around a frequent pricing adjustment to
reflect fair market value. As at November 2007, Rio Tinto had signed some
6.5 million tonnes per annum of hybrid contracts; and

. Long-term contracts with regular re-pricing.
By way of sensitivity, the current difference between the spot iron ore price and the price
of iron ore delivered pursuant to 2007 term contracts is about US$100 per tonne. On
15 million tonnes this would equate to US$1.5 billion of revenue before tax
This announcement is one component of this approach.
