per pound above 2006 mainly as a result of increasedmachinery hire, maintenance, fuel, oil and labour costs.The higher labour costs were due to the one-off bonuspayments on the conclusion of the mine-port unionand plant union negotiations during the year.At El Tesoro, cash costs increased to US 109.8 centsper pound compared with US 78.6 cents per poundin 2006. The main reasons for these increases werehigher energy costs and, to a lesser extent, increasedsulphuric acid costs (due to higher prices andconsumption levels).Cash costs at Michilla for 2007 were US 143.5 centsper pound, US 17.1 cents per pound higher than 2006.The increase compared to the previous year wasmainly due to increased energy costs, the impact ofthe bonus payment following the early conclusion ofthe labour negotiation during the year, and higher costsof third party services.Review of PerformanceTurnover, EBITDA, depreciation and amortisation,operating profit, capital expenditure and net assetsare analysed on a segmental basis in Note 5 to thefinancial statements.Turnover2007 2006US$m US$mTurnover 3,826.7 3,870.0Turnover from copper concentrate and copper cathodesTurnover from copper concentrate and copper cathodesales from the Group’s three mines decreased by7.3% to US$2,915.9 million, compared withUS$3,144.7 million in 2006. In 2007, sales of copperconcentrate and copper cathodes represented 76.2%of Group turnover and therefore revenues dependsignificantly on LME and realised copper prices.A one cent change in the average copper pricefor the year would affect turnover and profit beforetax by US$9.4 million and earnings per share byUS 0.5 cents, based on production volumes in2007, and without taking into account the effectsof provisional pricing and hedging activity.Tolling charges for copper concentrate at LosPelambres decreased from US$254.0 million in 2006to US$169.4 million in 2007, mainly due to reducedprice participation as a result of the 2007 calendaryear negotiations. Tolling charges are deducted fromconcentrate sales in reporting turnover and hencepartly offset the effect of improved copper prices.In 2007 turnover also included a loss of US$14.0million on commodity derivatives at El Tesoro andMichilla which matured during the year, recognisedunder the hedge accounting provisions of IAS 39“Financial Instruments: Recognition and Measurement”which were applied with effect from 1 January 2007.As explained below, during 2006 losses on thecommodity derivatives were recognised withinother operating expenses.FINANCIAL REVIEWGroup turnover in 2007 was US$3,826.7 million,1.1% below the US$3,870.0 million achieved in 2006.The slight decrease mainly reflected the impact oflower sales volumes and realised prices for copper,partly offset by the effect of higher molybdenumprices and volumes, reduced tolling charges forcopper concentrate and increased sales at thetransport and water divisions. The reasons for theimproved prices and changes in volumes are explainedin this Financial Review on pages 22 to 24 as wellas in the discussion contained in the Chairman’sReview on pages 5 to 21.Turnover from by-productsTurnover from by-products at Los Pelambres increasedby 30.6% to US$726.7 million in 2007 compared withUS$556.3 million in 2006, mainly due to highermolybdenum market prices. Molybdenum revenues(net of roasting charges) were US$676.4 million(2006 – US$513.8 million). A one dollar change in theaverage molybdenum price for the year would affectturnover and profit before tax by US$22.5 million,and earnings per share by US 1.1 cents, based onproduction volumes in 2007, and without taking intoaccount the effects of provisional pricing.Antofagasta plc Annual Report and Financial Statements 2007 25
