1. Highlights

• Quarterly revenues as of March 31, 2006 grew 31.1% to 118,367 million pesos. This increase was due to growth in volume sales of 22.4% and due to a rise in prices for raw materials.
• The Company's operating income increased 25.3%, despite continuous, sustained increases in the costs of principal raw materials, such as copper and aluminum, which were partially offset by price increases and higher unit sales. SG&A expenses increased 7.3% compared to the same quarter last year due to increased business activity.
• Net income for the first quarter of 2006 rose 61.9% to 6,451 million pesos compared to 3,986 million pesos in the first quarter of 2005. This result was mainly the product of an increase in operating income to 1,919 million pesos, a rise in non-operating income to 1,135 million pesos, and an increase in income tax, minority interest and other expenses to 587 million pesos.

2. Consolidated Income Statement Highlights (Exhibits 1 & 2)

Net Income First quarter net income in 2006 was 6,451 million pesos, up 61.8% compared to the 3,986 million pesos profit posted the same period the previous year. This result was the product of an increase in operating income to 1,919 million pesos, an rise in non-operating income to 1,135 million pesos, and increases in income tax, minority interest and other expenses to 587 million pesos.

Revenues Revenues in the first quarter of 2006 totaled 118,367 million pesos, an increase of 31.1% compared to the prior year. This increase in consolidated sales was due mainly to an increase in volume sales and to a rise in the average price of the product mix arising from the increase in copper prices.

Gross Income Gross income in the first quarter of 2006 increased 17.8% to 15,340 million pesos compared to 13,027 million pesos the prior year, due to an increase of 31.1% in sales value and an increase of 33.3% in operating costs. Operating costs were up mainly due to increased volume sales and higher prices for raw materials, such as copper and aluminum. On the London Metal Exchange the price for copper rose 56% (from $3,270/tonne to $5,103/tonne) in March 2006 compared to March 2005, while aluminum increased by 22.5% over the same period.

Operating Income First quarter operating income in 2006 was 9,512 million pesos, an increase of 25.3% compared to the 7,593 million pesos the previous year. This was the product of an increase of 17.8% in gross income to 2,313 million pesos, being partially offset by an increase of 7.3% in SG&A expenses arising from increased business activity.

Non-Operating Income The Company's non-operating losses in the first quarter were 888 million pesos, 56.1% less than the 2,023 million peso loss for the same period in 2005. This was due to a greater income resulting from exchange rate differences (net of hedge costs) of 1,385 million pesos. This was offset by lower non-operating income, due to the fact that in the first quarter of 2005 there was a reversal of provisions related to the accounts receivable of Optel, due to the purchase of 50% of the company. Earnings from exchange rate differences in the first quarter of 2006 were due mainly to the appreciation of the Brazilian real, and the dollar denominated debt of the Brazilian subsidiary Ficap, among others.

Income Tax In the first quarter of 2006, income tax was 1,783 million pesos compared to 1,514 million pesos in the same period the previous year.

Minority Interest Minority interest reflects the portion of profit/loss that corresponds mainly to the interest held in the company by minority shareholders in the Alusa, Indeco and Indalum subsidiaries. First quarter 2006 minority interest amounted to a loss of 396 million pesos compared to a loss of 71 million pesos for the same period 2005. This was due mainly to the higher net income of the Alusa subsidiary.

Brass Mills Revenues for this business unit increased 25.1% in the first quarter to 23,058 million pesos, compared to 18,436 million pesos the previous year. This was due mainly to the increase in copper prices and greater unit sales in Chile and to export destinations.

(in Bolivia).

4. Balance Sheet (Exhibit 7)

Assets Total Company assets as of March 31, 2006 were 379,356 million pesos, up 2.2% compared to the prior year.

Current Assets

Current assets increased to 192,232 million pesos, up 14.3% compared to the first quarter 2005. The increase is due mainly to higher receivables (15,259 million pesos), inventories (9,013 million pesos), as well as increased unit sales, higher raw materials prices, and due to an increase in deferred taxes and credits (5,463 million pesos). These increases were partially offset by a reduction of 2,085 million pesos in issues of diverse financial instruments compared to the previous year.

Fixed Assets

As of March 31 2006, fixed assets were 145,157 million pesos, 10.7% lower than the first quarter 2005, due to the appreciation of the Chilean peso against the dollar, and its effect on dollar denominated assets. Investment in current assets was 2,584 million pesos, equal to 79.3% of depreciation for the period.

Other Assets

Other assets rose 4.1% to 41,966 million pesos, compared to the same period last year. This was due to the inclusion of the Optel subsidiary in the financial statements.

Bank Debt

As of March 31, 2006 bank debt fell to 74,237 million, a 29.8% or 31,446 million pesos compared to the previous year.

Bonds

Bond debt fell 12.1% to 28,719 million pesos in the first quarter of 2006 compared to the same period last year.
