Earnings per share of 36.4 cents (1999 - 8.0 cents). Group copper production of 167,700 tonnes including 141,200 from Los Pelambres (1999 half year - 30,500 tonnes). Los Pelambres completion tests achieved so releasing the Group from completion guarantees and also releasing the US$133 million escrow account. El Tesoro project 40 per cent completed by June remaining on budget with first production scheduled for May 2001. Record Railway results continue with volumes up 7 per cent to 1.6 million tons. Dividend income of US$31.3 million received from Quinenco S.A. in May (1999 half year - US$5.5 million). Interim dividend increased 44 per cent to 3.25 pence per share (1999 interim dividend 2.25 pence per share). The successful commissioning of the Los Pelambres mine combined with improved copper prices enabled the Group to increase profit before tax by 449 per cent to US$100.0 million and earnings per share by 355 per cent to 36.4 cents. Group copper production was 167,700 tonnes (1999 half-year - 30,500 tonnes) including 141,200 tonnes from Los Pelambres and average cash costs down 30 per cent to 39.2 cents per pound. The El Tesoro project is on schedule with first production of cathodes expected in May 2001. The Group also benefited from a strong performance from its transport division and a higher dividend from its 33.6 per cent investment in Quinenco S.A. Jean-Paul Luksic, CEO of the mining division commented, 'The successful development of Los Pelambres has been a great achievement for Antofagasta, and the strength of that project is clearly demonstrated in these results. We are now evaluating the expansion potential for Los Pelambres and taken together with the El Tesoro project now under construction, we consider the Group has excellent opportunities for further growth in low cost copper mining.' Antofagasta is a UK-listed mining group based in Chile. In addition to copper mining, its interests include rail and road transport operations and a 33.6 per cent interest in Quinenco S.A. (LQ - NYSE).

The average copper price also improved to 80 cents per pound compared to 65 cents per pound in the first six months of 1999. Principally as a result of these factors, Group turnover increased from US$70.7 million to US$316.2 million and Group profit before tax increased from US$18.2 million to US$100.0 million. Interim Review of Operations Los Pelambres The development of the Group's 60 per cent owned Los Pelambres mine, which began in November 1997, was completed on schedule in the first quarter of 2000 and within the original US$1.36 billion budget. Production of concentrates started ahead of schedule in November 1999 and first shipments from its new Punta Chungo port facility at Los Vilos started in January 2000. Los Pelambres produced 141,200 tonnes of copper in concentrates and shipped 128,200 tonnes in the six months to June. Low treatment and refining charges this year have contributed to low average cash costs of 35.4 cents per pound, with total costs after depreciation and financial expenses amounting to 60.7 cents per pound. These factors enabled Los Pelambres to contribute US$54.6 million to Group profit before tax. On 10 July, the Group was released from all obligations under the Project Completion Guarantee. This guarantee, to ensure timely construction and start-up of operations, was issued by the Group and its Japanese partners in favour of the banks and institutions which financed the development. Los Pelambres' borrowings are now non-recourse and the Group's US$133 million escrow account and the charge over its 33.6 per cent interest in Quinenco S.A. which were established to secure the Completion Guarantee have been released. In July, a four-year collective bargaining agreement was reached with Los Pelambres' labour unions. Los Pelambres exceeded its planned capacity of 85,000 tonnes per day (tpd) in February and averaged 87,400 tpd in the first six months. Average processing levels in July were 90,000 tpd, and Los Pelambres is seeking to further optimise existing capacity by the end of the year. As a result of these higher processing levels, copper production this year is expected to be approximately 300,000 tonnes compared with an original forecast of 275,000 tonnes. Los Pelambres is also evaluating the advantages of expanding production capacity and a decision on the size of any expansion is expected in the following months. El Tesoro Construction began in November 1999 at the El Tesoro project, immediately following completion of the US$205 million project financing agreements. At the end of June, US$105 million of the total US$296 million budget had been spent and US$70.5 million drawn down from the financing facilities. The project remains on budget with 40 per cent completed by June and first production is expected in May 2001. El Tesoro will be a heap-leach SX-EW operation with an annual production of 75,000 tonnes and average cash costs of 40 cents per pound in the first five years. This will place the El Tesoro mine among the lowest cash cost producers worldwide. El Tesoro is owned 61 per cent by the Group and 39 per cent by Equatorial Mining Ltd, a subsidiary of AMP. Michilla Michilla's new mine plan has extended its operations to 2007. Reserves are now 28.3 million tonnes with an average copper grade of 1.28 per cent. The mine plan involves expanding the existing open pit by successive Phases as well as continuing the operation of the underground mine. During this period total capital expenditures will amount to US$36 million in mine expansion and plant upgrading. Michilla is continuing its exploration programme to identify additional reserves. Cathode production to June was 25,400 tonnes compared with 25,700 tonnes in 1999. The concentrator produced a final 1,100 tonnes prior to being mothballed in February 2000 (1999 half-year - 4,800 tonnes). Today, sulphide as well as oxide ores are being treated by leaching rather than using the traditional flotation method for sulphides. Cash costs at Michilla increased to 59.4 cents per pound compared with 55.9 cents per pound in the same period last year, due to a higher waste to ore ratio during the present expansion of the open pit. Total costs were 78.8 cents per pound compared with 68.6 cents in 1999 due to the adoption of more conservative depreciation policies in 2000. A hedging programme involving 12,500 tonnes of copper until May 2000 was implemented in March 1999 at an average price of 71.8 cents per pound. This was done during a period of copper price weakness, which contributed to an operating loss of US$1.6 million. Michilla is cash positive, having low debt levels and low on-going capital expenditure requirements and made a distribution of US$18.3 million to its shareholders in May. Future production is currently unhedged and reflects the stronger outlook for copper prices. Exploration The Group continued with its exploration programmes in Peru and Chile,spending US$2.4 million in the first six months of the year. The two main targets were the Magistral prospect in Peru and the area surrounding the El Tesoro properties near Calama in Chile. At Magistral, the Phase 2 drilling programme was completed in August and a mineral resource calculation is now in progress. The Group is financing the drilling programme over three years in order to acquire a 51 per cent interest in the project. This will increase to a 65 per cent interest on completion of a feasibility study. In Chile, further exploration also demonstrated the presence of a copper-gold porphyry resource at Esperanza which is located south of the Tesoro-NE deposit, containing 10 million tonnes of copper oxides with an average copper grade of 0.62 per cent and 150 million tonnes of copper sulphides, with an average copper grade of 0.81 per cent and 0.46 grammes of gold per ton. Transport and other services Tonnage carried in the first six months this year increased by 7 per cent to 1.6 million tons compared to 1.5 million tons in 1999 while ton-kilometres increased 11 per cent. Turnover from the Group's transport operations based in northern Chile increased from US$25.6 million to US$28.1 million and operating profits from US$9.6 million to US$10.7 million. Planned production increases at existing mines such as El Abra and Escondida indicate that current tonnage levels can be maintained for the next few years. The Group restructured its investment in the Bolivian Railway network by exchanging its 12 per cent interest in the Oriental Railway for an increased stake in the Andino Railway, which connects directly to the FCAB network in Chile. The Group now controls 50% of the Andino, the results of which have been consolidated from the beginning of the year. The Andino contributed US$5.8 million to turnover and US$1.1 million to operating profit in the first six months of the year. Investments The Group holds a 33.6 per cent interest in Quinenco S.A., a diversified industrial and financial group listed in Santiago and New York with interests in the Southern Cone and Brazil. Income from Quinenco is accounted for on a dividends-received basis and in May 2000 the Group received US$31.3 million (1999 - US$5.5 million). This represents a distribution of 30 per cent of Quinenco's previous year's profits after tax and minorities, which included the profit on the sale of its banking and cable television interests. Difficult economic conditions throughout the region persisted longer into 2000 than anticipated and resulted in Quinenco reporting a loss after tax and minorities of US$12.6 million to June 2000. Nevertheless, underlying operating performance by its subsidiaries has begun to improve as the Chilean economy begins to emerge from recession. Operating profit was US$11.7 million compared with a loss of US$17.3 million in the same period in 1999. The market value of the Group's holding in Quinenco was US$353.8 million at 30 June 2000 and US$342.5 million at 28 August 2000. Interim Financial Review Results Profit before tax rose from US$18.2 million in the first six months of 1999 to US$100.0 million in 2000, an increase of 449 per cent and earnings per share rose from 8.0 cents to 36.4 cents, an increase of 355 per cent. The significant improvement came mainly from the production at Los Pelambres helped by higher copper prices and an increased dividend from Quinenco. Turnover increased from US$70.7 million to US$316.2 million, of which US$282.3 million was from the mining division and US$33.9 million from the transport division. Mining revenues included US$238.9 million from Los Pelambres and transport revenues included US$28.1 million from existing operations in Chile. Operating profits increased from US$3.2 million to US$92.1 million, including US$88.4 million in respect of Los Pelambres. The operating profit from the transport division was US$11.8 million which included a contribution of US$10.7 million from Chile. Operating profit is stated after depreciation and amortisation costs of US$54.6 million (1999 half-year - US$10.5 million). Income from fixed asset investments increased from US$5.6 million to US$31.4 million, due to the higher dividend received from Quinenco. During the year, the Group sold surplus assets from its El Chacay mine, resulting in a profit of US$3.9 million (US$3.3 million after tax). This amount has been separately disclosed as an exceptional item. Net interest expense was US$27.4 million, compared with net interest income of US$8.4 million in the 1999 half-year. This included interest costs of US$36.5 million relating to Los Pelambres. During 1999, these costs were capitalised while the project remained under development. Interest costs in El Tesoro will continue to be capitalised until a commercial level of operations has been achieved during 2001. Tax amounted to US$10.4 million, representing an effective tax rate (including deferred tax) of 10.4 per cent, compared with the statutory Chilean tax rate of 15 per cent. The lower tax rate arises mainly because the dividend from Quinenco is paid out of its post-tax profits and is not subject to further tax on receipt. Excluding this dividend, the effective tax rate would have been 15.2 per cent. Cash Flows Net cash inflow from operating activities increased to US$91.4 million in the first six months of 2000 from US$15.2 million in 1999. Net cash inflow was affected by the build-up of stocks and debtors as part of the Los Pelambres start-up, and excluding working capital movements, cash inflow would have been US$149.6 million (1999 half-year - US$14.2 million). Net capital expenditures in the period were US$165.8 million, compared with US$301.1 million in 1999 half-year when Los Pelambres remained under development. Amounts spent in 2000 relate mainly to the El Tesoro project and final construction costs in the first quarter, at Los Pelambres. Cash and debt At 30 June 2000, the Group had cash and deposits of US$344.4 million (1999 - US$292.0 million). This includes US$79.5 million held by El Tesoro to fund its development costs and US$131.9 million belonging to Antofagasta plc and held in escrow under the Los Pelambres project financing arrangements released on 10 July. Accrued interest on the escrow account was US$1.0 million. On 23 August 2000, US$56.5 million was paid to AMP for funding the Group's share of El Tesoro's development costs. The Group had total borrowings at 30 June of US$1,162.7 million (1999 - US$692.9 million). This included US$946.0 million provided to Los Pelambres under its project financing arrangements, of which 40 per cent is attributable to minority shareholders. These Los Pelambres borrowings are now non-recourse. Group borrowings also included US$70.5 million drawn down to date by El Tesoro under its project financing arrangements, of which 39 per cent is attributable to minority shareholders. These borrowings will become non-recourse when the El Tesoro project satisfies its completion test, expected 2002. Group borrowings also included US$130.1 million provided to Los Pelambres and El Tesoro in the form of subordinated loans and, as explained above, part of this has since been paid to AMP. In addition to interest already being serviced, Los Pelambres will start repaying the principal amount of its project debt in semi-annual instalments. The first repayment of US$44.8 million is due in December this year. After this, the Group's total borrowings are expected to reduce progressively. Balance Sheet Shareholders' funds increased from US$887.3 million at the beginning of the year to US$947.0 million, reflecting mainly profit after tax and minorities for the period. Minority interests increased from US$216.3 million at the beginning of the year to US$250.4 million. This resulted from the acquisition and consolidation of the Andino, further contributions from minority shareholders to complete the Los Pelambres project and share of profit after tax. Dividends An interim dividend of 3.25p (1999 interim - 2.25p) will be paid on 13 October 2000 to ordinary shareholders on the Register at the close of business on 15 September 2000. Current trading prospects The outlook for the world economy remains favourable with continued growth in the United States, improving industrial production in Europe and Japan and further recovery in the largest emerging Asian economies. Copper prices have continued to improve and LME inventory levels have declined steadily from a high of 843,000 tonnes in March 2000 to 453,000 tonnes on 28 August. Copper prices averaged 80 cents in the first six months of this year (1999 first six months 65 cents), and are now approximately 84 cents. There is a growing consensus among commodity analysts that the copper market is now in deficit and that copper prices should continue to improve. With the start-up of operations at Los Pelambres, Group copper production is expected to be 350,000 tonnes this year and to exceed 400,000 tonnes next year when El Tesoro enters production. Following its transformation into a major low-cost producer, the Group is well placed to benefit from any further improvement in copper prices.

The lower effective tax rate arises principally because the dividend of US$31.3 million (£19.9 million) received from Quinenco is paid out of Quinenco's post-tax profits and is not subject to further tax on receipt. 7 Earnings per share Earnings per share is calculated on profit after tax, minority interest and preference dividends giving adjusted earnings of US$71.8 million (£45.8 million; 1999 half year - US$15.1 million ; £9.2 million) and based on 197,171,399 (1999 half year - 190,171,399) ordinary shares in issue throughout the period. Earnings per share excluding exceptional items is calculated on the same basis but excluding a gain on exceptional items of US$3.3 million (£2.1 million; 1999 half year - nil). 8 Dividends The Board has declared an interim dividend of 3.25p (1999 half year - 2.25p) per ordinary share for payment on 13 October 2000 to shareholders on the Register at the close of business on 15 September 2000. Dividends are declared gross, but dividends payable to United Kingdom shareholders will be paid net of witholding tax. 9 Tangible fixed assets US Dollars Rolling stock, Freehold Permanent plant, Mining Total land and way and machinery buildings works and water distribution US$'m US$'m US$'m US$'m US$'m Net book value 1 January 2000 30.6 33.3 39.4 1,532.5 1,635.8 Acquisition - 9.5 16.8 - 26.3 Additions - 0.4 2.0 192.9 195.3 Disposals - - (0.1) (3.3) (3.4) Depreciation (0.2) (0.9) (2.1) (51.4) (54.6) Exchange 0.1 - - - 0.1 30 June 2000 30.5 42.3 56.0 1,670.7 1,799.5 (unaudited) Sterling Freehold Permanent plant, Mining Total land and way and machinery buildings works and water distribution £'m £'m £'m £'m £'m Net book value 1 January 2000 19.2 21.5 24.1 951.8 1,016.6 Acquisition - 5.9 10.4 - 16.3 Additions - 0.2 1.3 123.2 124.7 Disposals - - (0.1) (2.1) (2.2) Depreciation (0.1) (0.6) (1.4) (32.8) (34.9) Exchange 0.7 0.4 0.9 63.5 65.5 30 June 2000 19.8 27.4 35.2 1,103.6 1,186.0 (unaudited) 10 Disposal of associate and acquisition of subsidiary Investments in associates US$'m £'m 1 January 2000 Transferred to investments in subsidiaries 20.6 13.2 and consolidated (20.6) (13.2) 30 June 2000 (unaudited) - - At 31 December 1999, the Group held a 36.5% interest in Empresa Ferroviaria Andina S.A. ('Andino') and a 12 per cent interest in Empresa Ferroviaria Oriental S.A. ('Oriental'), rail networks operating in Bolivia. These investments were jointly controlled by the Group and its strategic partner, the Cruz Blanca group, which held 13.5 per cent of the Andino and 38 per cent of the Oriental. At the beginning of 2000, the Group exchanged its interest in the Oriental for Cruz Blanca's interest in the Andino. The Group now holds 50 per cent of the Andino and no longer has an interest in the Oriental. The Group exercises management control over the Andino and has the right to appoint the majority of the company's board. Accordingly this investment has been treated as a subsidiary and consolidated from 1 January 2000. Turnover and operating profit for the Andino have been disclosed as acquisitions in the profit and loss account. 11 Other investments US$'m £'m 1 January 2000 and 30 June 2000 (unaudited) 185.8 108.3 The book value of quoted investments at 30 June 2000 included above was US$185.5 million, and the corresponding market value was US$357.3 million (1999 half year - US$ 344.4 million).

Earnings per share of 36.4 cents (1999 - 8.0 cents). Group copper production of 167,700 tonnes including 141,200 from Los Pelambres (1999 half year - 30,500 tonnes). Los Pelambres completion tests achieved so releasing the Group from completion guarantees and also releasing the US$133 million escrow account. El Tesoro project 40 per cent completed by June remaining on budget with first production scheduled for May 2001. Record Railway results continue with volumes up 7 per cent to 1.6 million tons. Dividend income of US$31.3 million received from Quinenco S.A. in May (1999 half year - US$5.5 million). Interim dividend increased 44 per cent to 3.25 pence per share (1999 interim dividend 2.25 pence per share). The successful commissioning of the Los Pelambres mine combined with improved copper prices enabled the Group to increase profit before tax by 449 per cent to US$100.0 million and earnings per share by 355 per cent to 36.4 cents. Group copper production was 167,700 tonnes (1999 half-year - 30,500 tonnes) including 141,200 tonnes from Los Pelambres and average cash costs down 30 per cent to 39.2 cents per pound. The El Tesoro project is on schedule with first production of cathodes expected in May 2001. The Group also benefited from a strong performance from its transport division and a higher dividend from its 33.6 per cent investment in Quinenco S.A. Jean-Paul Luksic, CEO of the mining division commented, 'The successful development of Los Pelambres has been a great achievement for Antofagasta, and the strength of that project is clearly demonstrated in these results. We are now evaluating the expansion potential for Los Pelambres and taken together with the El Tesoro project now under construction, we consider the Group has excellent opportunities for further growth in low cost copper mining.' Antofagasta is a UK-listed mining group based in Chile. In addition to copper mining, its interests include rail and road transport operations and a 33.6 per cent interest in Quinenco S.A.
