Antofagasta PLC03 May 2007 Antofagasta plc 3 May 2007 Quarterly Production Report - Q1 2007 Highlights • Group copper production in Q1 was 105,900 tonnes, in line with forecast but 9.0% below the quarterly average for 2006. • Molybdenum production at Los Pelambres in Q1 was 2,100 tonnes compared with the quarterly average of 2,500 tonnes in 2006, mainly due to inventory movements and lower recoveries in the quarter. • Group cash costs for Q1 were 35.8 cents per pound compared with 40.2 cents per pound in the 2006 full year, due to improved by-product credits and lower tolling charges.

Thisreduction was mainly due to the expected decrease in grades and also to thelower plant throughput resulting from the higher proportion of hard ore thisquarter. This was partly offset by the improved recoveries due to the increasein plant capacity. Molybdenum production in the first quarter was 2,100 tonnes, compared with thequarterly average in 2006 of 2,500 tonnes. The decrease resulted mainly frominventory movements. Lower recoveries and the lower plant throughput were offsetby higher molybdenum grades. Cash costs during the first quarter of the year decreased to 4.2 cents perpound, compared with 16.4 cents per pound in the 2006 full year. This resultedfrom a combination of lower tolling charges and higher by-product credits,partly offset by higher on-site costs. Tolling charges decreased by 14.0 centsper pound, due to improved annual terms and lower price participation.By-product credits (expressed in cents per pound of copper produced) improved by6.6 cents as a result of lower copper production in the quarter and highermolybdenum prices. On-site costs increased by 8.3 cents mainly due to the impactof lower ore grades and plant throughput. As explained in the Group's 2006 preliminary results announcement of 13 March2007, there are a number of claims currently at first instance or on appeal inthe Chilean courts against third parties (either governmental authorities orformer owners of land in the El Mauro area) which relate to the Mauro tailingsdam project. None of these cases are directly against Los Pelambres, but in somecases the company has participated in proceedings in case an eventual judgementaffects the Mauro tailings dam project. The Group is confident that these claimswill not have any material impact on the project. Construction of the dam iscontinuing in accordance with the original schedule and the project is expectedto be completed as planned by the end of 2007. El Tesoro Cathode production at El Tesoro in the first quarter was 23,600 tonnes,marginally above the quarterly average for 2006. This reflected the increase inore grades, partly offset by the decrease in plant throughput and slightly lowerrecoveries. Cash costs in the first quarter were 87.4 cents per pound, 8.8 cents above theprevious full year but below forecast levels. The increase resulted from thehigher waste to ore ratio, and also from the higher prices and consumption ofsulphuric acid. Michilla Michilla produced 11,600 tonnes of copper cathodes in the first quarter of theyear, in line with forecast but slightly below the quarterly average of 2006.This was due to minor reductions in throughput and ore grades, offset byimproved recoveries due to the higher proportion of sulphide ore processed. Cash costs in Q1 were 123.1 cents per pound, 2.6% lower than the 2006 full year.This was mainly due to lower transportation costs. Transport The transport division continued to perform strongly. Rail tonnages in the firstquarter were 1,253,000 tons, 11.7% higher than the quarterly average for 2006.This compensated for a reduction in road tonnages. Water The water division also performed well with volumes up by 6.6% over thequarterly average for 2006 mainly due to increased sales to industrialcustomers.
