Toronto Stock Exchange: EDV                                                          
        
George Town, Grand Cayman, September 21, 2010 - Endeavour Mining Corporation ("Endeavour") is pleased to announce that Computershare Investor Services Inc. (the "Depositary") has advised the Company that the share sale on behalf of all former U.S. holders of common shares of Etruscan Resources Inc. ("Etruscan") has been completed.  Accordingly, all former U.S. holders of Etruscan's common shares are encouraged to complete their letters of transmittal (available at Etruscan's profile on www.sedar.com) and return their letters of transmittal along with underlying share certificates to the Depositary in order to receive their consideration pursuant to Endeavour's acquisition of Etruscan (the "Etruscan Acquisition").

Important Notice to U.S. Shareholders

Due to U.S. securities law considerations, Endeavour did not offer or distribute its securities in the United States or to, or for the account or benefit of, U.S. Persons or persons in the United States ("U.S. Holders") in respect of the Etruscan Acquisition, except in very limited circumstances.  U.S. Holders of Etruscan shares are not entitled to receive Endeavour shares and will instead receive the CDN$0.26 in cash plus the pro rata proceeds of the sale by the Depositary of the Endeavour shares that U.S. Holders would have been entitled to receive.  The Depositary has now effected the sale of all such Endeavour shares through the facilities of the Toronto Stock Exchange.  Endeavour will pay the costs and fees of the Depositary and brokers in connection with such sales. Payment to the U.S. Holders will be based on the average sale price received for such sales.

A letter of transmittal was mailed on September 10, 2010 to all registered Etruscan shareholders and is also available at Etruscan's profile at www.sedar.com or by contacting Endeavour directly.  All U.S. Holders should return a completed letter of transmittal and the certificates formerly representing the Etruscan shares together with such other documentation, if any, as provided for in the letter of transmittal to the Depositary at the address specified in the Letter of Transmittal (or give instructions to their broker to do so, if their shares are registered in street form) as soon as possible, in order to receive their cash payment representing their pro rata interest in the proceeds from the sale of such Endeavour shares.
