TSX: MAI   

NASD-OTCBB: MNEAF    

SPOKANE, WASHINGTON – October 25, 2007 – Minera Andes Inc. (TSX: MAI and US OTC: MNEAF) has accepted an offer letter from Macquarie Bank Limited (“Macquarie Bank”, Australian Stock Exchange, ASX: MBL) to provide a loan facility of US$10 million.  The main purpose of the facility will be to provide additional funding to Minera Andes for its 49% portion of the costs of the exploration, sustaining capital, cost overruns and expansion related costs of the San Jos� silver/gold project that entered its production commissioning phase in the third quarter of 2007.

The US$10 million debt facility provided by Macquarie Bank is subject to completion of documentation. The funds from the facility have been delivered and Toronto Stock Exchange approval received. The debt financing is for part of Minera Andes’ share of the October cash call for costs of mine construction, expansion of the exploration program which will include drilling new targets, expanding the reserves and resources, and for general working capital. In addition, since this facility is an extension of a previously used debt facility with Macquarie Bank, we realize a significant savings in cost to document and complete the loan.

Allen Ambrose, president of Minera Andes, said: "As the San Jos� project is continuing to grow in size and scope, making adjustments in the mine plan now allows us to make significant cost savings of the operations down the road.  The Macquarie Bank bridge facility provides us with additional funds to complete our objectives."

The commercial terms of the loan include a facility fee of 1.75% of the principal amount of the loan and interest of Libor plus 2.75% p.a., currently totaling approximately 7.79% p.a.  In addition, Minera Andes has issued share purchase warrants acquiring 4,066,390 Common Shares of Minera Andes at an exercise price of C$2.41 per share. The warrant exercise price was calculated at a 20 percent premium to the volume weighted average of Minera Andes’ common stock determined from the ten business days prior to October 22, 2007. The warrants issued are exercisable until September 30, 2009 the same term as the loan.  The warrants and the underlying common shares will have a hold period until February 25, 2008.  A success fee of US$100,000, being one percent of the principal amount of the facility, is payable to Xystus Limited for assisting with the structuring and negotiation of the loan facility.
