SPOKANE, WA — (MARKET WIRE) — February 6, 2006 — Minera Andes Inc. (TSX-V: MAI) (OTC: MNEAF) is pleased to announce that drilling will commence this week at the Los Azules porphyry copper system in the San Juan province, central Argentina. Both a core and a reverse circulation drill rig have been mobilized to the property.

A total of 36 holes, totaling approximately 9,000 meters, are planned for the current campaign. The holes will be drilled to a depth of 250 meters. This drilling will test a known area of leachable (chalcocite) copper mineralization currently defined by 8 previous drill holes. In addition, the area is defined by a deep penetrating IP chargeability anomaly and, on its eastern flank, a magnetic low recognized in both airborne and ground surveys. The area to be drilled covers approximately 2,500 by 750 meters. Holes will be drilled at a grid spacing of 200 meters east-west and 400 meters north-south.

The exploration program is designed to define an inferred resource and provide sufficiently detailed information to allow the completion of a Preliminary Assessment (as defined by NI 43-101) of the property. To this end the engineering firm of Roscoe Postle and Associates has been retained to monitor the program and prepare the NI 43-101 resource estimate and Preliminary Assessment report. The field work will be managed by Nivaldo Rojas and Associates under the supervision of Minera Andes’ technical staff.

Drilling at Los Azules encountered features typical of many porphyry copper systems. In the discovery zone, strongly leached cap rock extends from 65 to 161 meters depth followed by an enriched zone of secondary copper mineralization (chalcocite) overlying a zone of mixed secondary and primary (chalcopyrite) copper mineralization. The best hole to date contained a 117-meter interval of 0.61% copper in the enriched zone (for details see News Release dated May 4, 2004).
