Minera Andes Inc.: Response to TNR Gold Corp. News Release Regarding Los Azules Litigation

TORONTO, ONTARIO--(Marketwire - Jan. 13, 2012) - Minera Andes Inc. (the "Corporation" or "Minera Andes") (TSX:MAI)(OTCBB:MNEAF) refers to the news release issued by TNR Gold Corp. on January 12, 2012 and wishes to take this opportunity to respond.

In its news release, TNR Gold Corp. has offered to settle its ongoing litigation with Minera Andes over the ownership of certain portions of Minera Andes' Los Azules project in exchange for a payment to TNR Gold of US$125 million. Minera Andes received substantially the same settlement offer from TNR Gold on January 10, 2012, however, with a deadline for acceptance of approximately 24 hours, which period was subsequently extended to approximately 48 hours.

The offer was considered by both the Board of Directors of Minera Andes and by its Special Committee comprised of independent directors and formed for the purpose of reviewing the proposed business combination with US Gold Corporation. After due consideration and having received the input of the Special Committee, the Board of Directors of Minera Andes resolved unanimously to reject the offer from TNR Gold as unreasonable. Minera Andes continues to reject TNR Gold's claims and intends to continue to vigorously defend against those claims and looks forward to resolving this matter in the courts of British Columbia.

Although the litigation has been ongoing for several years and the proposed business combination with US Gold was first announced over six months ago, TNR Gold has chosen to make its offer by press release less than a week in advance of the shareholders meeting to consider the proposed business combination with US Gold. As a result, Minera Andes believes that TNR Gold is simply seeking to take advantage of its last minute timing in an effort to cloak an unreasonable settlement offer for its own benefit.

The Board of Directors of Minera Andes remains firmly of the view that the proposed business combination with US Gold on the terms of the arrangement agreement dated September 22, 2011 is fair to shareholders and in the best interests of Minera Andes and recommends that shareholders vote in favour of the arrangement at the special meeting on January 19, 2012.
