Dividends

Details of dividends proposed in relation to the year are given in the Directors’ Report and in Note 12 to the financial statements.

Dividends are declared in US dollars but may be paid in either dollars or sterling. Shareholders on the register of members with an address in the United Kingdom receive dividend payments in sterling, unless they elect to be paid in dollars. All other shareholders are paid by cheque in dollars, unless they have previously instructed the Company’s registrar to pay dividends by bank transfer to a sterling bank account, or they elect for payment by cheque in sterling. The Company’s registrar must receive any such election before the close of business on the record date of 7 May 2010.

Dividends are paid gross without deduction of United Kingdom income tax. Antofagasta plc is not resident in the United Kingdom for tax purposes and dividends paid by Antofagasta are treated the same way as dividends received from any other foreign company.

If approved at the Annual General Meeting, the final dividend of US 20 cents per ordinary share will be paid on 10 June 2010 to shareholders on the register at the close of business on 7 May 2010.

The conversion rate for final dividends to be paid in sterling will be set on 12 May 2010.
