In addition, the Corporation has agreed to grant the Underwriters an option (the "Over-Allotment Option") to purchase additional units of Minera Andes to raise additional gross proceeds of up to 15% of the Offering, on the same terms and conditions as the Offering, exercisable any time, in whole or in part, up to 48 hours prior to the closing date of the Offering.  If the Over-Allotment Option is exercised in full, the total gross proceeds to Minera Andes will be Cdn$23,028,750.  For additional detail, please refer to the Corporation’s news release dated July 24, 2009.

The Offering is expected to close on or about August 19, 2009 and is subject to normal regulatory approvals, including the approval of the Toronto Stock Exchange.
