"Drill results at Marta Sur show a consistent trend of anomalous values within shoots plunging toward the north. We believe that this data indicates a trend of higher grade mineralization towards the north. At Marta Este, drill results display wide intervals of silver and gold mineralization with higher grade material within the core of the mineralized envelope," commented Ken Hicks, President of Argentex.

"The new higher-grade intervals at Marta Este represent some of the best precious metal mineralization received to date at Pinguino. Marta Este is one of the most prolific and consistently mineralized gold-silver veins at Pinguino with mineralization exposed at surface and continuing strongly to depth," said Ken Hicks.

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., 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.
