VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 3, 2011) - Argentex Mining Corporation ("Argentex" or the "Company") (TSX VENTURE:ATX)(OTCBB:AGXMF) is pleased to release additional drill results from its 2011 exploration program at the Pinguino project, located in Santa Cruz province, Argentina. In addition, Argentex desires to comment on the recent spike in the trading volume of its stock on both the OTC BB and the TSX Venture Exchange.

Market Comment

The Company knows of no reason for the recent spike in trading volume of its common shares. As a result of its August 19, 2011 financing, the company has in excess of $10 million in cash and short-term investments and is not aware of any unannounced information that may have caused this spike.

Corporate Update

Argentex continues to actively explore its Pinguino, Contreras and Condor properties. In addition, it continues to look forward to the update of its 2009 NI 43-101 compliant resource estimate during the current quarter. Argentex expects this update to include 25,924 meters of drilling results from its 2010 and 2011 exploration programs. The Company intends to use this updated report as a guide for future exploration.

"These Marta Centro and Marta Noroeste holes were targeted to test the limits of mineralized shoots along the veins. At Marta Centro, drilling data indicates the main shoot is extended to 340 meters deep with silver equivalent grade times width levels of >500 g/t Ag Eq. This shoot still remains open at depth. At Marta Noroeste, the last five RC holes were located in marginal areas, and defined the shape of the outer limits of the shoots," commented Ken Hicks, President of Argentex.

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.

To date the Company has completed over 56,000 meters of drilling in over 500 holes on 19 veins. More than 50 individual vein segments have been identified to date, comprising more than 75 line-kilometers of strike length.

Quality Assurance

Samples selected for analysis are sent to Acme Analytical Laboratories' sample preparation lab in Mendoza, Argentina. From there, sample pulps are sent to Santiago, Chile for fire assay gold analysis and to Vancouver, Canada for Group 1DX multi-element MS-ICP analysis. Samples with over-limit zinc, lead, silver and/or copper are reanalyzed using an ore-grade high detection limit 7AR analysis, also conducted in Vancouver. Acme Analytical Laboratories is an accredited ISO 9000:2001 full-service commercial laboratory with its head office located in Vancouver. Referee analyses will be carried out by Alex Stewart (assayers) Argentina S.A. in Mendoza, Argentina. Argentex, Acme and Alex Stewart all maintain comprehensive and independent Quality Control/Quality Assurance programs.

Exploration on the Pinguino property is being conducted under the supervision of Mr. Kenneth Hicks, P.Geo.
