Appr Escondida Norte Copper

BHP Billiton Limited 16 June 2003 BHP Billiton Limited is issuing this announcement to fulfil disclosure obligations arising from its secondary listing on the London Stock Exchange. The text of this release is identical to that issued by BHP Billiton Plc earlier. Date 16 June 2003 Number 21/03 BHP BILLITON APPROVES ESCONDIDA NORTE COPPER PROJECT BHP Billiton and its partners have approved the development of the Escondida Norte copper project in northern Chile, as part of Escondida's operating strategy to maintain copper production capacity in future years. Brad Mills, President and CEO of BHP Billiton Base Metals said that the Escondida Norte open pit would be located 5 km from the existing Escondida mining operations. Escondida Norte will mine a satellite ore body that will be able to provide higher-grade copper ore to the two existing Escondida concentrators, which will also continue to receive ore from the Escondida mine. 'Due to the proximity of the Norte open pit to the Escondida operations, we can develop this property in a manner that maximizes the synergies with the existing Escondida infrastructure. Norte will provide the necessary feed to maintain capacity at Escondida above 1.2 million tonnes per annum of copper in concentrate and cathode through the end of 2008,' Mr Mills said. Ore grades at the existing Escondida mine are forecast to continue to decline over the next several years. Norte will enable Escondida to maintain existing capacity. The development of the Norte open pit will increase production flexibility and reduce operational risks associated with a single mine source, as well as further reduce the cost of production from an already low base. First copper production from the Norte open pit is scheduled for the fourth quarter of CY2005. Development costs are estimated at US$400 million (BHP Billiton share US$230 million). These costs include installation of a primary crusher, construction of an overland conveyor, maintenance and operating support facilities, some new mining equipment, the transition of a portion of the current Escondida mobile equipment fleet to the Norte open pit and waste pre-stripping of the new pit. Escondida Norte's combined proved and probable ore reserves are estimated at 526 million tonnes of sulphide ore at an average copper grade of 1.42% and a cut-off grade of 0.7%, giving an ore reserve life of approximately 17 years. The information in this report that relates to Ore Reserves is based on information compiled by Dr Jonathan M. Gilligan Ph.D., B.Sc.
