Argentex Provides Update on the Pinguino Mineral Resource Estimate

 Vancouver, BC, Canada -- January 13, 2012 - Argentex Mining Corporation ("Argentex" or the "Company") (TSX-V: ATX, OTCBB: AGXMF) reports on the proposed update to its Pinguino mineral resource report.
The estimated completion of the update -- initially projected for the end of 2011 -- has been pushed back into the second quarter of 2012.

About Pinguino

Argentex's 10,000-hectare advanced silver and gold exploration Pinguino project is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. The Deseado Massif is an active region of mining with four precious metal mines currently in production, and includes multiple active advanced and early stage exploration projects.

Pinguino is easily accessible, situated approximately 400 meters above sea level in low-relief topography. An existing system of all-weather roads provides year-round access to the property. Argentex believes that recent high-grade precious metal discoveries within newly tested structures of the district scale vein system at Pinguino show potential for the development of a significant silver-gold resource. Argentex has drilled approximately one third of the known vein system, comprised of approximately 50 individual veins, with more than 75 line-kilometers of strike length.

Exploration on the Pinguino property is being conducted under the supervision of Mr. Kenneth Hicks, P.Geo. Argentex's President and a "Qualified Person" (QP) as defined by Canada's National Instrument 43-101. Mr. Hicks is not considered "independent" of the issuer as he is part of Company management.
