SPOKANE, Wash., June 15, 2004 (PRIMEZONE) -- Minera Andes Inc. (TSX Venture Exchange:MAI) (OTCBB:MNEAF) is meeting this week with representatives of their joint venture partner Mauricio Hochschild & Cia. Ltda. (MHC) at the San Jose Project in Argentina to obtain a quarterly update on the progress of the development, infrastructure, and underground construction of the site. The work is being done in preparation to a production decision expected later this year.

According to Allen Ambrose, President of Minera Andes, "It's exciting to see a project discovered by our exploration staff to move to a production decision milestone. We look forward to reporting the continued progress on this project."
