Iron Ore Price Settlement

Rio Tinto PLC 29 March 2000 IRON ORE PRICE SETTLEMENT Rio Tinto's wholly owned Hamersley Iron has today reached agreement with Nippon Steel Corporation on prices for Hamersley fine, lump and Yandi iron ore deliveries for the contract year commencing 1st April, 2000. The price of fine ore will increase by 4.35% to US cents 27.79 per dry long ton unit. The price of lump ore will increase by 5.77% to US cents 36.84 per dry long ton unit. The price of Yandi ore will increase by 4.35% to US cents 26.12 per dry long ton unit (see accompanying note). Delivery tonnage for the year has been agreed at a similar level to FY99. A comparison with 1999 prices, in US cents per dry long ton unit, is as follows:- FY99 FY00 % change Fine ore 26.63 27.79 +4.35% Lump ore 34.83 36.84 +5.77% Lump premium 8.20 9.05 Yandi ore 25.03 26.12 +4.35% For further information contact: Media Relations Investor Relations John Hughes Peter Jarvis + 44 207 753 2331 + 44 207 753 2401 Website: www.riotinto.com Notes:- * Iron ore is predominantly traded on the world market under long term contract. * Japan, Korea and Taiwan operate on a fiscal year basis commencing on 1st April each year. Europe and China are on a calendar year basis. * The global reference price settlement is expressed as a percentage increase or decrease from the previous year. * The reference price is usually established for fines ore first because this represents 60% of the traded market. Prices for lump and pellets are then usually determined as a premium to the fines ore price. * Once the annual percentage change is negotiated, Japanese iron ore prices are denominated in US cents per dry long ton unit, reflecting a common base per unit of iron content. * In 1999, Hamersley exported 59.6 million wet metric tonnes of ore * Comparing prices is a somewhat complex process based on 'iron units' (not tonnes), often requiring lengthy conversions: * To determine the US$ price per tonne, the conversion is:- US cents per dry long ton unit x Iron Content Iron content for Hamersley fine and lump ore is 64% and for HI Yandi 58% * 'Dry long ton unit' is the imperial form of measurement - and can be converted to metric units and adjusted for moisture content of the ore when normally reporting tonnages; * To convert quantities from dry long tonnes to dry metric tonnes, multiply dry long tons by 1.016; * The moisture content of ores differ
