Minera Andes: Excellent Drill Results from Los Azules Copper Project. Marketwire. May 2010.

TORONTO, ONTARIO–(Marketwire – May 6, 2010) – Minera Andes Inc. (the “Corporation” or “Minera Andes”) (TSX:MAI)(OTCBB:MNEAF) is pleased to announce 12 additional, and very encouraging, drill holes from our 100% owned Los Azules copper project in San Juan Province in Argentina. Highlights include a step-out hole 300 meters to the north of any previous drilling which contains 1.12% Cu over 62.5 meters (Hole 51). The other intercepts are from in-fill drilling and confirm the presence of an important high-grade secondary enrichment zone: 1.03% Cu over 101 meters (Hole 53A); 0.84% Cu over 52 meters and 0.83% Cu over 38 meters (Hole 57); 0.99% Cu over 84 meters (Hole 58); 0.90% Cu over 74 meters (Hole 59); and, 1.04% Cu over 168.2 meters (Hole 61A).

Exploration commenced in mid-December 2009, and four diamond drills have been operating on the project. A total of 22 diamond drill holes were completed this season for a total of 10,007 meters. Most of the drilling is infill drilling, although step-out holes drilled at the north end of the existing deposit extend the mineralization further north. The deposit remains open to the north, to the west, and at depth. In addition, we completed 615 meters of RC drilling in three holes that were drilled for geotechnical testing.

The objective of this field season’s drilling program was to expand the known limits of mineralization, delineate the high-grade secondary enrichment zone and to increase the confidence level of the existing Los Azules resource. This resource contains 922 million tonnes grading 0.55 percent copper, equivalent to 11.2 billion pounds of copper, based on drilling completed through 2008. Also included in this resource is a high-grade core of 161 million tonnes grading 0.87 percent copper, which is equivalent to 3.1 billion pounds of copper. The known resource covers an area approximately 4 kilometers by 1 kilometer, and is open at depth and laterally. Please refer to figure 2 for a drill hole map.
