Vancouver, B.C., January 28, 2009 -- Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) is pleased to provide an update on reconnaissance fieldwork completed at its Plata Leon property, which adjoins our Pinguino property to the northwest.  Recently completed fieldwork has identified multiple gossanous outcrops at Plata Leon that appear to be similar to outcrops located at Pinguino which, when drilled to depth, were found to be deep-penetrating sulphide-rich polymetallic veins. 

“Argentex continues to use effective, low-cost methods to expand the drill-defined polymetallic mineralization at the Pinguino deposit into adjacent areas along the Tranquilo Trend,” said Ken Hicks, President of Argentex.  “Our early-stage exploration model at Pinguino suggested there might be a close association between the northwest-trending Tranquilo fault and local epithermal mineralization.  This led us to acquire the 24,710-acre (10,000-hectare) Plata Leon property through staking.  Our discovery of gossans and vein outcrops at Plata Leon supports our original exploration model and expands the overall potential.  We believe that this gives us an even greater foothold in what is turning out to be a very prospective area.”

Follow-up exploration is currently being planned for the new veins discovered at Plata Leon.  A total of 14 veins have been discovered in three areas.  Two of those areas are located along the Tranquilo Trend and are associated with possible intrusions at depth.  Both Plata Leon and Pinguino are located on the Tranquilo Trend, a major regional structural break that Argentex believes is an important factor in the formation of epithermal mineralization in the area.  Argentex is the largest holder of mineral rights along the Tranquilo Trend. 

Selected grab samples from Plata Leon have been collected and submitted for analysis.  Analytical results are pending and further investigation is anticipated.

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.
