Minera Andes Inc. Announces Third Quarter 2011 Financial Results

(all figures in US dollars)

TORONTO, ONTARIO -- (Marketwire) -- 11/10/11 -- Minera Andes Inc. (the 'Company' or 'Minera Andes') (TSX: MAI)(OTCBB: MNEAF) is pleased to announce net income of $6.8 million ($0.02 per share basic and diluted) for the quarter ended September 30, 2011, an increase of $12.4 million compared to a net loss of $5.6 million ($0.02 loss per share basic and diluted), for the same period in 2010.

The increase is primarily attributable to the strong performance of silver and gold prices and its impact on the San Jose Mine where our 49% ownership interest is reflected in our income from investment in Minera Santa Cruz S.A. ('MSC'). Income from this investment increased from $5.0 million in Q3 2010 to $11.2 million in Q3 2011. The average weighted gross sale price for silver increased from $21.31 per oz in Q3 2010 to $35.82 per oz in Q3 2011, a 68% increase; the average weighted gross sale price for gold increased from $1,270 per oz to $1,726 per oz over the same period, a 36% increase. Comparing Q3 2010 to Q3 2011, silver ounces sold at MSC increased from 1,220,000 oz to 1,410,000 oz reflecting an increase of 16% while gold oz sold decreased slightly from 20,000 oz to 18,000 oz, a decrease of 10%.

Other factors contributing to the increase in net income in 2011 compared to 2010 include a $9.2 million unrealized loss on the fair value of our warrant liability recorded during Q3 2010 which did not recur in 2011 as the Company no longer has any warrants outstanding; this was partially offset by a $2.0 million increase in professional fees relating to the proposed combination with US Gold Corporation. At September 30, 2011, the Company had $45.0 million in cash and cash equivalents and short-term investments and is debt free.


Update to Minera Andes Press Release on October 27, 2011

Decree No. 1722 was issued by the Executive Branch of Argentinean government on October 25, 2011, and published in the Official Gazette on October 26, 2011, which re-establishes the obligation for mining companies, including MSC, to repatriate to Argentina all foreign currency revenues obtained from mining exports. Considering that Argentine exporters in general are subject to the obligation of repatriating their export revenues into the country, and alleging fairness and equity reasons, the Executive Branch has re-established the obligation to settle in the Single and Free Foreign Exchange Market, all revenues arising from exports performed by companies engaged in the development of mining projects. The special exceptions for mining industries previously granted in 2003 and 2004 have been eliminated.

The Company has been advised by MSC that their preliminary estimates indicate an additional $2 million in their annual pre-tax operating expenses (on a 100% basis) as a result of the increased foreign exchange and bank transaction costs caused by the issuance of this decree.

Our financial statements and management's discussion and analysis are available under the Company's profile at www.sedar.com and www.sec.gov.
