Vancouver, B.C., August 25, 2008 -- Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) is pleased to announce that it plans to exhibit core samples from its polymetallic Pinguino property at Argentina Mining 2008.  The conference is one of the country’s premier mining events and takes place in Mendoza, Argentina from August 26-28, 2008.

Argentex recently completed the fieldwork portion of the company’s largest-ever exploration program, which included more than 20,000 meters (65,616 feet) of new HQ diamond drilling completed during the 2007-2008 season.  Pinguino is one of the most prominent advanced exploration projects in Patagonia and contains a unique discovery of base metal, precious metal and indium within a single property.

A high-value strategic metal, indium is a significant component of thin-film flat panel displays and CIGS (copper-indium-gallium-deselenide) solar cells, an increasingly popular application within the potentially huge green-energy market.  CIGS solar cells are substantially cheaper than those made using silicon, and can be produced in light-weight, physically flexible formats – making them suitable for a wide range of applications.

Argentina Mining 2008 is a biennial event that showcases the latest advancements of major and junior mining and exploration companies working in Argentina.  Additional information about the conference is available at

About Pinguino
Argentex’s Pinguino property is located in Argentina’s Patagonia region, within the Deseado Massif of Santa Cruz province. The zinc-indium-lead-silver-gold-copper discovery at Pinguino in 2006 marked a major exploration milestone for the company.  This was the first discovery of its kind in the region, unique in that it contains both silver-gold and indium-enriched base-metal mineralization in multiple zones that remain open-ended along strike and to depth.  Since 2006, exploration of base-metal-rich targets has expanded beyond discoveries at Marta Centro and Yvonne and now encompasses more than eight mineralized veins, including the Yvonne Sur, Yvonne Norte, Sonia, Kasia, Savary and Luna veins, within an area of approximately 8.0 square kilometers (3.0 square miles).

Pinguino is easily accessible, situated approximately 400 meters (1,312 feet) above sea level in low-relief topography.  An existing system of all-weather roads provides year-round access to the property.

Argentex Mining Corporation is a junior mining exploration company with significant holdings in the Patagonia region of Argentina. It recently fulfilled the terms of its option agreement on the property and now owns 100% of the mineral rights to the Pinguino property.  Argentex also owns 100% mineral rights to more than 30 other mineral properties with over 377,490 acres (152,766 hectares) of prospective land located in the Santa Cruz and Rio Negro provinces of Argentina.  Shares of Argentex common stock trade on the TSX Venture Exchange under the symbol ATX and under the symbol AGXM on the OTCBB.

Exploration on the Pinguino property is being conducted under the supervision of Mr. Kenneth Hicks, P.Geo., Argentex's President and a "qualified person" as defined by Canada’s National Instrument 43-101.  Mr. Hicks has read and approved the contents of this release.
