Minera Andes Announces Exploration Drilling Results at the San Jose Mine

TORONTO, ONTARIO--(Marketwire - June 10, 2011) -Minera Andes Inc. (the "Corporation" or "Minera Andes") (TSX:MAI)(OTCBB:MNEAF) announces the results of exploration drilling at its 49% owned San José mine in Santa Cruz Province, Argentina during the first quarter of 2011. A total of 24 diamond core holes totaling 5,411 meters were drilled during the quarter. The drilling consisted of infill and of step-out drilling on known veins in and around the mine area. Five of the infill holes contained high-grade intercepts. Details of the drilling, which include several high-grade holes, is provided in Exhibit 1. The location of the principal veins is shown in Exhibit 2. Further drilling will be required to estimate the resources intercepted by the drilling.

The vein system at San José continues to be open at depth and laterally. As a result of the discovery of the east-west trending Micaela-Sofia vein system last year, previous drill results are being reinterpreted to define new drilling targets in and near the mine area in conjunction with new surface magnetic data and existing induced polarization geophysics data.

During the first half of 2011, 800 line-kilometers of surface magnetic coverage is being run over the area southeast of the mine area. This will be followed up with an additional 2,200 line-kilometers of surface magnetic coverage in the southeast portion of the joint venture property during the second half of the year. The geophysical data will be used to define new drilling targets outside of the main mine area for drilling during the second half of the year.
