(the 'Company' or 'Minera Andes') (TSX: MAI)(OTCBB: MNEAF) announces that it has received proceeds of $19.1 million from the exercise of 15.3 million share purchase warrants (the 'Warrants'). The Warrants were issued pursuant to a 'bought deal' underwritten financing completed in August 2009 and had an original expiry date of August 19, 2014. As a result of the Company issuing a notice of accelerated expiry on December 30, 2010, based on Minera Andes' stock trading above $2.50 Canadian for 20 consecutive days, the expiry date was accelerated to January 31, 2011. Each Warrant was exercisable to purchase one common share of the Company at a price of $1.25 Canadian per common share.

   'We are very pleased that our share price performance has been strong
   enough to allow us to accelerate the expiry of the Warrants. With our
   treasury full and positive cash flow from our San Jose Mine Joint
   Venture, we are now well funded to advance our exploration programs and
   pre-feasibility work.' stated Rob McEwen, Chairman and CEO.
