Toronto, ON,  September 19, 2007 -- Argentex Mining Corporation (OTCBB: AGXM) is pleased to announce results for the 18 drill holes recently completed on six new sulphide targets at its Pinguino property in Santa Cruz, Argentina.  The six targets returned significant intersections of precious and base metals -- including high gold, silver and base-metal values -- from widely spaced holes testing shallow depths.  The results significantly expand Argentex's mineralized footprint at Pinguino and all six targets remain open along strike and to depth.

"The initial discovery in 2006 of base metals, precious metals and indium-rich mineralization at Pinguino was the first discovery of its kind in Argentina's Patagonia region.  Now, our latest drill program has significantly expanded this existing mineralized footprint beyond the Marta Centro and Yvonne veins to include six new areas of the property," said Ken Hicks, President of Argentex.  "We look forward to commencing an extensive property-wide exploration program, which is scheduled to include additional geophysics, trenching and drilling, later this month."

The discovery of parallel, subparallel and conjugate mineralized veins exponentially increases the exploration potential at Pinguino.  A number of holes in the current drill program intersected structures within the near-surface oxidized portion of the mineralized system, showing a general enrichment in gold-silver values.  Deeper intercepts from holes that penetrated below this horizon show significantly higher base metal and sulphide content.

Highlights of the results from the 18 holes include hole P094-07, which intersected 3.5 meters of 268.6 grams per tonne (g/t) silver, 2.22% lead, and 56 g/t indium; hole P101-07, which intersected 4.0 meters of 3.06 g/t gold and 69 g/t indium; and hole P105-07, which hit 1.5 meters of 4.48 g/t gold and 33 g/t indium.  Significant lead and zinc values were also returned from all zones, including hole P113-07 with 1.85 meters of 17% lead-zinc.  Lead is a significant component of the base-metal mineralization discovered at Pinguino. The price per pound of lead has increased from $0.50 per pound one year ago to a recent spot price of approximately $1.44 per pound.

Prior to this latest drill program, drill testing of known base-metal mineralization at Pinguino had been limited to the Marta Centro and Yvonne veins, which represent only 10% of the geophysical anomalies defined to date.  Argentex anticipates commencing an extensive property-wide exploration program later this month.

Details of the analytical results for the major intersections of the18 drill holes are highlighted in the following table:

The latest drill program included 18 HQ diamond drill holes covering 1,357 meters (4,452 feet).  Six new zones were drilled to test near-surface gossanous vein in bedrock within newly completed trenches. Samples were submitted to Acme Analytical Labs for analysis.

About Pinguino

Argentex's Pinguino property is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. Both silver-gold and base-metal discoveries have been made through the completion of approximately 9,350 meters (30,675 feet) of diamond drilling to date.  Mineralization remains open-ended along strike and at depth, and numerous targets remain to be tested by drilling.  Previous exploration in 2006 was focused on zinc-indium-lead-silver-gold-copper discoveries in the Marta Centro and Yvonne areas of the property.  A similar style of mineralization has been recently discovered at the Yvonne Sur, Yvonne Norte, Sonia, Kasia, Savary and Luna veins.

Pinguino is easily accessible, situated approximately 500 meters (1,640 feet) above sea level in low-relief topography.  An existing system of all-weather roads provides year-round access to the property.

Quality Assurance

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.

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.  Drilling was conducted by Connors Drilling, a Canadian company with an office in Mendoza, Argentina.
