Antofagasta PLC03 May 2006 3 May 2006 Antofagasta plc Quarterly Production Report - Q1 2006 Highlights • Group copper production in Q1 of 107,000 tonnes is in line with forecast but 8.4% below the quarterly average for 2005. • Molybdenum production at Los Pelambres in Q1 was 2,000 tonnes, compared with 8,700 tonnes for the 2005 full year. • Group cash costs for Q1 were 49.7 c/lb compared with 13.9 c/lb in 2005, mainly due to lower molybdenum prices in Q1 compared with 2005.

The decreasewas mainly due to lower throughput which resulted from a higher proportion ofharder primary ore under the current phase of the mine plan. The decrease inproduction was also due to lower recoveries, partly compensated by the higherore grade. Molybdenum production in the first quarter was 2,000 tonnes, 7.7% below thequarterly average for 2005. The decrease was mainly due to the lower throughputof ore and lower recoveries, offset by the higher molybdenum grade. Cash costs in the quarter increased to 29.8 c/lb, compared with negative 17.1 c/lb for 2005. The increase was mainly due to the lower by-product credit whichdecreased by 32.3 c/lb, resulting from lower market molybdenum prices (whichaveraged US$23.0/lb in the first quarter against US$32.0/lb in 2005). Molybdenumproduction was also lower this quarter. Treatment and refining charges increasedby 7.2 c/lb, mainly due to price participation by smelters as the LME copperprice increased in the first quarter of 2006. On site and shipping costs rose by7.4 c/lb compared with 2005 but remained in line with the fourth quarter of lastyear. The increase was due mainly to the lower production level, together withhigher shipping costs, fuel prices and a stronger Chilean peso. El Tesoro Cathode production at El Tesoro was 20,800 tonnes in the first quarter, 3,800tonnes below the quarterly average for 2005. This was mainly due to the expectedlower ore grade combined with lower recoveries, compensated in part by thehigher processing level following the completion of the 10.5 million tonnes peryear throughput expansion at the beginning of this year. Cash costs at El Tesoro were 79.6 c/lb this quarter, 13.5 cents higher than theaverage for 2005, due to the lower production level and higher movement ofmaterial at the mine (which increased 19.3% compared with 2005). Higher inputcosts included fuel and explosives prices and copper price-linked payments. Michilla Michilla produced 12,100 tonnes of copper cathodes in the first quarter, anincrease of 4.5% over the quarterly average for 2005. This was due to higher oregrades and improved recoveries, partly offset by the lower expected treatmentlevel. Cash costs were 120.2 c/lb, marginally above the average for 2005 but lower thanthe current forecast for the year. The cash costs at Michilla mainly reflecttransport and loading costs, as well as higher input costs and the strongerChilean peso. These factors were mostly offset by the higher production level. Transport The transport division continued to perform strongly, with total rail tonnagesup 5.3% and road tonnages up 0.6% over the quarterly average for 2005. Water The water division had a strong first quarter, with volumes rising to 9.3million cubic metres. This represented an increase of 12.5% compared with thequarterly average of 2005 and 11.9% with the first quarter of 2005. Thisreflected both higher domestic consumption and increased sales to miningcustomers.
