Minera Andes Welcomes Lawsuit by Hochschild Mining plc

TORONTO, ONTARIO--(Marketwire - March 17, 2010) - Minera Andes Inc. ("Minera Andes") (TSX:MAI)(OTCBB:MNEAF) received this morning a Summons and Complaint in connection with a lawsuit commenced by affiliates of Hochschild Mining plc ("Hochschild") against Minera Andes (and a subsidiary) in the State of New York.

The lawsuit pertains to the project finance loans made by Hochschild to Minera Santa Cruz S.A., the company operating the San José Mine and jointly owned by subsidiaries of Minera Andes (49%) and Hochschild (51%).

Hochschild, among other claims, claims Minera Andes has refused to sign formal project loan documentation and caused undue delay of the same. Neither party can receive any funds from Minera Santa Cruz until such agreements are signed. In addition, no funds are due to Hochschild from Minera Andes under these agreements unless such funds are first provided to Minera Andes by Minera Santa Cruz. Despite claims by Hochschild, Minera Andes has and continues to be willing to execute definitive loan documentation with Hochschild that reflects the commercial agreement of the parties as set out in a letter agreement dated October 10, 2006.

Hochschild has demanded that the Court order Minera Andes to sign formal loan documents for the project finance loans, enjoin Minera Andes from interfering with the making of payments by Minera Santa Cruz in relation to the project finance loans, require Minera Andes to repay to Hochschild the benefits that Minera Andes has received from the project finance loans and establish the priority of other shareholder loans owed by Minera Santa Cruz to Hochschild and Minera Andes.

Said Rob McEwen, Chairman, President and CEO of Minera Andes:

"We look forward to reaching a resolution in respect of these project finance loan documents. Regrettably, despite significant effort on the part of Minera Andes, it appears that the Courts of the State of New York may provide our shareholders with the best venue for ensuring fair treatment by our joint venture partner so that both parties can begin receiving the profits generated by the San José mine".

Minera Andes is reviewing in detail the claim by Hochschild with its legal advisors and will respond accordingly. We believe the details of this case will speak for itself.
