3rd Quarter Results

Antofagasta PLC 29 November 2007 Antofagasta plc Unaudited Results for the Third Quarter ended 30 September 2007 London, 29 November 2007 Highlights Nine Nine months months ended ended 30 September 30 September Full year 2007 2006 Change 2006 US$'m US$'m % US$'m Group turnover 2,838.6 2,980.4 -4.8% 3,870.0 ======== ======== ======== Group EBITDA 2,152.0 2,292.8 -6.1% 2,957.3 ======== ======== ======== Turnover Group turnover in the nine months ended 30 September 2007 was US$2,838.6 million compared with US$2,980.4 million in the same period of 2006, reflecting reduced copper sales volumes and lower realised copper prices, partly offset by higher molybdenum volumes and prices, and lower tolling charges. LME copper prices averaged 321.5 cents per pound compared with 299.9 cents per pound in the nine months ended 30 September 2006. Pricing adjustments on provisionally invoiced sales, while remaining positive, were lower than the comparable period in 2006, resulting in an average realised copper price of 348.1 cents per pound compared with 354.2 cents per pound in the nine months ended 30 September 2006. Market molybdenum prices, which did not differ significantly from prices realised by Los Pelambres, averaged US$29.5 per pound in the nine months to 30 September 2007, an increase from the average price of US$24.5 per pound in the comparative nine month period. The volume of copper sold was 298,700 tonnes (nine months ended 30 September 2006 - 339,100 tonnes). The decrease was partly due to lower production of 312,600 tonnes in the period (nine months ended 30 September 2006 - 334,300 tonnes), mainly as a result of reduced ore grades at Los Pelambres. Sales in the 2007 period were also affected by timing differences in shipping and loading schedules which resulted in an increase in inventories at the end of September which were shipped in October. Molybdenum sales and production volumes in the period were 7,400 tonnes (nine months ended 30 September 2006 - sales volume of 6,900 tonnes and production volume of 7,000 tonnes). The transport and water divisions continued to perform well, with both businesses generating increased volumes and revenues. Further details of production and sales volumes and realised prices by mining operation are given in Note 2, and an analysis of turnover by business segment is given in Note 3. Further details of the operating performance of each mine and the rail and water division are also given in the Group's third quarter production report released on 31 October 2007. EBITDA Group EBITDA in the nine months ended 30 September 2007 was US$2,152.0 million, compared with US$2,292.8 million in the nine months ended 30 September 2006. The decrease in EBITDA mainly resulted from the reduction in turnover described above and higher on-site and shipping costs at the Group's mining operations, partly offset by lower costs for the Group's commodity hedging programme compared with the nine months ended 30 September 2006. As reported on 31 October 2007, weighted average cash costs for the Group's mining operations, which are stated net of by-product credits, were 30.2 cents per pound in the nine months ended 30 September 2007. This compared with 41.0 cents per pound in the comparative period in 2006. The decrease was largely due to improved by-product credits and lower tolling charges at Los Pelambres, both of which are included in the financial statements within turnover. By-product credits (expressed in cents per pound of copper produced) improved as a result of the higher molybdenum prices and volumes outlined above, as well as the impact of the reduced copper production in the period. Tolling charges were lower as a result of lower benchmark terms for the 2007 calendar year as compared with 2006 and reduced price participation with smelters. Weighted average on-site and shipping costs (excluding by-product credits and tolling charges) were 88.1 cents per pound (nine months ended 30 September 2006 - 67.7 cents per pound). Further details of the cash costs of each mine are given in the Group's third quarter production report of 31 October 2007. The amount recognised in the income statement during the current period in respect of the Group's commodity hedging programme was a loss of US$11.8 million, recorded within turnover as the Group has applied the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007. This loss recognised during the current period relates to commodity instruments which matured during the period. During the nine months ended 30 September 2006 a charge of US$94.7 million was recognised in respect of commodity hedging, recorded within other operating expenses. Further details of cash costs by mining operation are given in Note 2, and an analysis of EBITDA by business segment is given in Note 3. Details of commodity instruments are given in Note 5. Basis of Information The Group turnover and EBITDA figures included in this release for the nine-month period ended 30 September 2007 are presented on a basis consistent with the accounting policies used in the Group's 2006 Annual Report and Financial Statements (except in relation to the application by the Group of the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007 as set out in Note 5) under International Financial Reporting Standards and Interpretations ('IFRS'). The Group's three mining companies, Los Pelambres, El Tesoro and Michilla, will today also file quarterly financial statements under Chilean GAAP for the nine-month period ended 30 September 2007 with the Chilean securities regulator, the Superintendencia de Valores y Seguros de Chile ('SVS'). These filings are in accordance with mining tax legislation introduced in Chile in 2005 which requires companies that have elected to enter a tax stability regime to publish quarterly financial information from the 2006 financial year onwards. This release includes a summary of the Chilean GAAP income statement, balance sheet and cash flow statement for each of the three mining companies to be filed with the SVS.

General information and accounting policies These unaudited third quarter results are for the nine-month period ended 30 September 2007. The Group turnover and EBITDA information, including all comparatives, have been prepared on the basis of the accounting policies set out in the Group's statutory accounts for the year to 31 December 2006 (except in relation to the application by the Group of the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007 as set out in Note 5) and in accordance with applicable International Financial Reporting Standards and Interpretations (IFRS) which have been endorsed by the European Union. While the turnover and EBITDA information contained in this nine month results announcement has been computed in accordance with IFRS, this announcement does not itself contain sufficient information to comply with IFRS. The information included in this announcement for the nine month periods ending 30 September 2006 and 30 September 2007 is unaudited. The information contained in this announcement for the year ended 31 December 2006 does not constitute statutory accounts. The statutory accounts for that year have been approved by the Board and reported on by the auditors, and have been delivered to the Registrar of Companies. The auditors' report on those accounts was unqualified and did not contain statements under section 237(2) of the Companies Act 1985 (regarding adequacy of accounting records and returns) or under section 237(3) (regarding provision of necessary information and explanations). The comparative information contained in Note 2 of this announcement is not derived from the statutory accounts for the year ended 31 December 2006 and is accordingly not covered by the auditors' report. 2.

The Group owns 60% of Los Pelambres, 100% of El Tesoro (61% prior to 24 August 2006) and 74.2% of Michilla. (ii) Los Pelambres produces copper and molybdenum concentrates, and the figures for Los Pelambres are expressed in terms of payable metal contained in concentrate. Los Pelambres is also credited for the gold and silver contained in the copper concentrate sold. El Tesoro and Michilla produce cathodes with no by-products. (iii) Cash costs are a measure of the cost of operational production expressed in terms of cents per pound of payable copper produced. Cash costs are stated net of by-product credits and include tolling charges for concentrates at Los Pelambres. Cash costs exclude depreciation, financial income and expenses, hedging gains and losses, exchange gains and losses and corporation tax for all three operations. By-product calculations do not take into account mark-to-market gains for molybdenum at the beginning or end of each period. (iv) Excluding by-product credits (which are reported as part of turnover) and tolling charges for concentrates (which are deducted from turnover), weighted average cash costs for the Group (comprising on-site and shipping costs in the case of Los Pelambres and cash costs in the case of the other two operations) increased from 67.7 cents per pound in the first nine months of 2006 to 88.1 cents per pound in the first nine months of 2007 (68.0 cents per pound in the year ended 31 December 2006). (v) Realised copper prices are determined by comparing turnover from copper sales (grossing up for tolling charges for concentrates) with sales volumes for each mine in the period. Realised molybdenum prices at Los Pelambres are calculated on a similar basis. In the current period realised prices reflect gains and losses on commodity derivatives, which are included within turnover. The classification of these amounts within turnover is due to the application of the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007. Prior to this point, gains and losses on commodity derivatives were included in other operating income or expense, and so are not reflected within the realised price figures for the comparative periods. (vi) The totals in the tables above may include some small apparent differences as the specific individual figures have not been rounded. (vii) The production information in Note 2(a) and the cash cost information in Note 2(b) is derived from the Group's production report for the third quarter of 2007 published on 31 October 2007. 3.

Turnover from the water concession is stated after elimination inter-segmental sales to the transport and mining divisions of US$0.3 million (nine months ended 30 September 2006 - US$0.6 million; full year 2006 - US$0.6 million). (ii) Turnover includes the effect of both final pricing and mark-to-market adjustments to provisionally priced sales of copper and molybdenum concentrates and copper cathodes. Further details of such adjustments are given in Note 4. (iii) In the current period turnover includes realised losses on commodity derivatives at Michilla of US$11.9 million, and gains of US$0.1 million at El Tesoro. The classification of these amounts within turnover is due to the application of the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007. Prior to this point, gains and losses on commodity derivatives were included in other operating income or expense. In the comparative periods, other operating expense included losses at El Tesoro of US$46.9 million in the nine months ended 30 September 2006 and US$44.8 million in the 2006 full year, and losses at Michilla of US$47.8 million in the nine months ended 30 September 2006 and US$39.7 million in the 2006 full year. Further details of such gains or losses are given in Note 5. (iv) Los Pelambres produces and sells copper and molybdenum concentrates. It is also credited for the gold and silver content in the copper concentrate it sells. Turnover by type of metal is analysed below to show separately the amounts prior to deduction of tolling charges, the tolling charges involved and the net amounts included in turnover. El Tesoro and Michilla do not generate by-products from their copper cathode operations. (v) EBITDA is calculated by adding back depreciation, amortisation and disposals of plant, property and equipment and any impairment charges to operating profit from subsidiaries. (vi) An adjustment of US$4.2 million has been made to the comparative EBITDA of the water concession for the period ended 30 September 2006 as a result of a classification between depreciation and cash operating costs. The adjustment had no effect on turnover or operating profit for that period and there have been no adjustments required to the comparative amounts for the 2006 full year. 4. Embedded derivatives - provisionally priced sales Copper and molybdenum concentrate sale agreements and copper cathode sale agreements generally provide for provisional pricing of sales at the time of shipment, with final pricing being based on the monthly average London Metal Exchange copper price or monthly average molybdenum price for specified future periods. This normally ranges from 30 to 180 days after delivery to the customer. Under IFRS, both gains and losses from the marking-to-market of open sales are recognised through adjustments to turnover in the income statement and to trade debtors in the balance sheet. The Group determines mark-to-market prices using forward prices at each period end for copper concentrate and cathode sales, and period-end month average prices for molybdenum concentrate sales due to the absence of a futures market for that commodity. The mark-to-market adjustments at the end of each period and the effect on turnover in the income statement for each period are as follows: Balance sheet - ------------------ net mark to market effect on debtors ------------------------------------- At 30.09.07 At 30.09.06 At 31.12.06 US$'m US$'m US$'m Los Pelambres - copper 30.9 (2.7) (110.1) concentrate Los Pelambres - tolling (8.5) (0.9) 7.6 charges for copper concentrate Los Pelambres - molybdenum (0.1) 7.0 (3.9) concentrate El Tesoro - copper cathodes 2.7 0.1 1.3 Michilla - copper cathodes 1.3 (0.1) (0.6) -------- -------- -------- 26.3 3.4 (105.7) ======== ======== ======== (a) Copper sales Nine months ended Nine months ended Full year 2006 30 September 2007 30 September 2006 US$'m US$'m US$'m US$'m US$'m US$'m US$'m US$'m US$'m Los El Michilla Los El Michilla Los El Michilla Pelambres Tesoro Pelambres Tesoro Pelambres Tesoro Copper Copper Copper Copper Copper Copper Copper Copper Copper concentrate cathodes cathodes concentrate cathodes cathodes concentrate cathodes cathodes Provisionally 1,342.2 512.7 255.5 1,529.7 471.8 245.2 2,175.5 653.1 326.0 invoiced gross sales ------- ------ ------ ------ ------ ------ ------ ------ ------ Effects of pricing adjustments to previous period invoices Reversal of 110.1 (1.3) 0.6 (33.2) (0.2) 0.1 (33.2) (0.2) 0.1 mark-to-market adjustments at the end of the previous period Settlement of (88.1) (6.6) (3.2) 169.2 22.1 0.6 169.2 2.0 0.6 copper sales invoiced in the previous period ------- ------ ------ ------ ------ ------ ------ ------ ------ Total effect 22.0 (7.9) (2.6) 136.0 21.9 0.7 136.0 1.8 0.7 of adjustments to previous period invoices in the current period Effects of pricing adjustments to current period invoices ------- ------ ------ ------ ------ ------ ------ ------ ------ Settlement of 129.5 12.6 5.1 234.7 (2.0) 12.5 197.6 8.6 8.8 copper sales invoiced in the current period Mark-to-market 30.9 2.7 1.3 (2.7) 0.1 (0.1) (110.1) 1.3 (0.6) adjustments at the end of the current period ------- ------ ------ ------ ------ ------ ------ ------ ------ Total effect 160.4 15.3 6.4 232.0 (1.9) 12.4 87.5 9.9 8.2 of adjustments to current period invoices Impact of - 0.1 (11.9) - - - - - - commodity derivatives recognised within turnover ------- ------ ------ ------ ------ ------ ------ ------ ------ Turnover 1,524.6 520.2 247.4 1,897.7 491.8 258.3 2,399.0 664.8 334.9 before deducting tolling charges Tolling (120.8) - - (192.5) - - (254.0) - - charges ------- ------ ------ ------ ------ ------ ------ ------ ------ Turnover net 1,403.8 520.2 247.4 1,705.2 491.8 258.3 2,145.0 664.8 334.9 of tolling ======= ====== ====== ====== ====== ====== ====== ====== ====== charges Copper concentrate Copper concentrate sales at Los Pelambres have an average settlement period of approximately four months from shipment date.

Commodity derivatives The Group periodically uses derivative financial instruments to reduce exposure to commodity price movements. The Group does not use such derivative instruments for speculative trading purposes. The Group has applied the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007. From that date, changes in the fair value of derivative financial instruments that are designated and effective as hedges of future cash flows have been recognised directly in equity, with such amounts subsequently recognised in the income statement in the period when the hedged item affects profit or loss. Any ineffective portion is recognised immediately in the income statement. Realised gains and losses on commodity derivatives recognised in the income statement have been recorded within turnover. Prior to 1 January 2007 derivatives were measured at fair value through the income statement, with gains or losses on commodity derivatives being recorded within other operating income or expense. The balance sheet mark-to-market adjustments at the end of each period and the total effect of commodity derivatives on operating profit in the income statement for each period are as follows: Balance sheet Income statement --------------- ------------------ Net financial asset/(liability) Total effect --------------------------------- -------------- At At At 31.12.06 Nine Nine Full year 30.09.07 30.09.06 months months 2006 ended ended 30 30 September September 2007 2006 US$'m US$'m US$'m US$'m US$'m US$'m El Tesoro (21.4) (19.5) - 0.1 (46.9) (44.8) Michilla (7.7) (8.9) 7.3 (11.9) (47.8) (39.7) -------- -------- -------- -------- -------- -------- (29.1) (28.4) 7.3 (11.8) (94.7) (84.5) ======== ======== ======== ======== ======== ======== The balance sheet mark-to-market effect is stated before taking into account any payments on account of margin calls. The US$11.8 million loss recognised within turnover during the nine months ended 30 September 2007 related to amounts realised on derivatives which matured in the period. During the period net mark-to-market losses before tax and minority interests of US$29.1 million were recognised within reserves (US$22.1 million after tax and minority interests). The Group had min/max instruments at 30 September 2007 for 73,200 tonnes of copper production (of which 68,400 tonnes relate to El Tesoro and 4,800 tonnes relate to Michilla), covering a period up to 31 December 2009. The weighted average remaining period covered by these hedges calculated with effect from 1 October 2007 is 12.7 months. The instruments have a weighted average floor of 255.5 cents per pound and a weighted average cap of 387.6 cents per pound. At 30 September 2007, the Group also had futures at Michilla for 4,200 tonnes of copper production, covering a period up to 31 December 2007. The weighted average remaining period covered by these hedges was 2.0 months and the weighted average price was 305.9 cents. It also had futures to both buy and sell copper production at El Tesoro, with the effect of swapping COMEX prices for LME prices without eliminating underlying market price exposure, covering a period to 31 January 2008. The remaining weighted average period covered by these instruments was 2.5 months and the weighted average price was 312.0 cents. Between 30 September 2007 and the date of this report the Group has entered into additional min/max instruments for 3,600 tonnes of copper production at Michilla, covering a period up to 31 December 2008. The weighted average period covered by these instruments calculated with effect from 1 October 2007 is 9.5 months. The instruments have a weighted average floor of 250.0 cents per pound and a weighted average cap of 500.0 cents per pound. 6.

Certain detailed lines in the individual statements have been combined for convenience. (ii) The balance sheets, income statements and cash flow statements above have been prepared under Chilean GAAP and therefore do not necessarily equate to the amounts that would be included in the Group's consolidated financial statements for a corresponding period either as to measurement or classification. (iii) The amounts disclosed above represent the full amount for each company and not the Group's attributable share. The Group owns 60% of Los Pelambres, 100% of El Tesoro (61% prior to 24 August 2006) and 74.2% of Michilla.

This normally ranges from 30 to 180 days after delivery to the customer. Under Chilean GAAP, the Group's accounting treatment is to value sales, which remain open as to final pricing at the period end, in aggregate at the lower of provisional invoice prices and mark-to-market prices at the balance sheet date. The Group determines mark-to-market prices using forward prices at each period end for copper concentrate and cathode sales, and period-end month average prices for molybdenum concentrate sales due to the absence of a futures market for that commodity. Under IFRS, both gains and losses from the marking-to-market of open sales are recognised through adjustments to turnover in the income statement and to trade debtors in the balance sheet. Under IFRS, the Group determines mark-to-market prices in the same way as under Chilean GAAP. This results in a GAAP adjustment in cases where the mark-to-market prices are higher than the provisional invoice prices. For Los Pelambres this results in a credit of US$23.4 million in respect of copper concentrate sales. The adjustment in respect of El Tesoro is a credit of US$2.6 million, and the adjustment in respect of Michilla is a credit of US$1.4 million. (ii) The Group uses derivative financial instruments to reduce exposure to commodity price movements. The Group does not use such derivative instruments for trading purposes. Under Chilean GAAP, such derivatives are held off the balance sheet. Gains or losses on derivative instruments are matched in the income statement against the item intended to be hedged. Such gains or losses are reflected by way of adjustment to turnover. The Group has applied the hedge accounting provisions of IAS 39 'Financial Instruments: Recognition and Measurement' with effect from 1 January 2007. From that date, changes in the fair value of derivative financial instruments that are designated and effective as hedges of future cash flows have been recognised directly in equity, with any ineffective portion recognised immediately in the income statement. Realised gains and losses on commodity derivatives recognised in the income statement have been recorded within turnover. Prior to 1 January 2007 derivatives were measured at fair value through the income statement, with gains or losses on commodity derivatives being recorded within other operating income or expense. For the comparative periods, any amounts included in turnover under Chilean GAAP were reclassified accordingly. (iii) Other IFRS and consolidation adjustments are not material either individually or in aggregate. This information is provided by RNS The company news service from the London Stock Exchange
