Argentex Continues To Expand Tranquilo Zone at Pinguino Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 23, 2011) - Argentex Mining Corporation ("Argentex" or the "Company") (TSX VENTURE:ATX)(OTCBB:AGXM) is pleased to release additional drill results from its recently completed 2011 exploration program at the Pinguino project, located in the Santa Cruz province of Argentina. The program consisted of 19,800 meters of drilling in 206 holes. To date, the Company has released 6,015 meters of drilling results from 67 of these holes, with approximately 70% of results remaining to be released over the next couple months.

Positive analytical results from additional drilling on the regional scale Tranquilo fault continue to expand the near surface silver-enriched mineralized zones. These new results reflect large mineralized intervals enveloping high-grade silver values in the center of the Tranquilo fault system. The Tranquilo is a major regional fault that transects the Pinguino property and is believed to be the strategic geological controlling structure in the region.

Results below are from the most recent 7 holes from the Tranquilo zone (a map of drill hole collars is available on the Company's web site at

"Tranquilo is one of the largest silver-gold mineralized structures on the Pinguino property. RC drilling during 2010 and 2011 has focused on near surface mineralization and continues to identify excellent high-grade silver intersections," commented Ken Hicks, President of Argentex. "We believe these results have significantly expanded the Pinguino resource and we look forward to receiving an updated NI 43-101 compliant resource estimate before the end of 2011."

In addition, on June 20, 2011, one of the Company's investors exercised a share purchase warrant pursuant to which it purchased 142,900 of the Company's common shares at an exercise price of CDN$0.90 per share for aggregate proceeds of approximately $131,500 (CDN$128,610).

About Pinguino

Argentex is currently advancing its highly prospective projects in Santa Cruz province, focusing primarily on its 100%-controlled Pinguino project. An early 2011 drill program of approximately 17,000 meters was increased to 19,800 meters due to positive results, and was comprised of 11,200 meters of RC drilling and 8,600 meters of core drilling. In total, 56,000 meters have been drilled on the project to date.

Argentex's 10,000-hectare Pinguino property 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 silver discoveries within newly tested structures of the district scale vein system at Pinguino show potential for the development of a significant silver resource.

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 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. Argentex's President and a "Qualified Person" (QP) as defined by Canada's National Instrument 43-101.
