Vancouver, B.C., May 20, 2008 -- Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) today announced results for another eight holes drilled during the continuing work program at its polymetallic Pinguino property located in Santa Cruz, Argentina.
Analytical results from Pinguino’s Marta Este zone include a 10.8-meter (35.4-foot) intersection that returned 3.1 grams per tonne (g/t) gold and 679 g/t silver. Marta Este is a silver-enriched zone located approximately 800 meters (2,600 feet) northwest and along strike from Marta Centro. In addition, a new drill hole from Marta Centro returned 10.7 meters (35.1 feet) of 34 g/t indium, 68 g/t silver and 7.3% combined lead-zinc.
“Drilling continues to define excellent silver mineralization at Marta Este and indium-enriched base metal values at Marta Centro,” said Ken Hicks, President of Argentex. “In addition, detailed mapping using high-resolution satellite imagery, which has been ongoing simultaneously with drilling, shows an additional 1.5 miles (2.5 kilometers) of veins within Pinguino’s existing mineralized system. Our ongoing work program, including detailed surface exploration and drill testing of numerous zones, continues to expand Pinguino’s potential.”
Results
Marta Este’s hole P154-08 returned 18.7 meters (61.4 feet) of 422 g/t silver and 1.9 g/t gold. Higher grade intervals within hole P154-08 include 10.8 meters (35.4 feet) of 679 g/t silver and 3.1 g/t gold, including a 4.1-meter (13.5-foot) contained interval of 1,561 g/t silver and 5.1 g/t gold. Drilling at Marta Este has been completed to a depth of approximately 230 meters (754 feet). Additional assay results are pending and will be reported after they are received and compiled.
Hole P140-08 at Marta Centro shows continued expansion of the indium-enriched base-metal mineralization along strike and to depth. Hole P140-08 returned 10.7 meters (35.1 feet) of 34 g/t indium, 68 g/t silver and 7.3% lead-zinc as well as two additional mineralized zones within the same hole. Drilling at Marta Centro has been completed to a depth of approximately 250 meters (820 feet). Further results will be reported after assays are received and compiled.
The following table displays selected analytical results for four holes drilled in Marta Este and one hole at Marta Centro:
*True widths are estimated to be 85-90% of the stated core length
Argentex continues to work with two independent drill contractors on its largest phase of drilling to date, which has so far surpassed 17,500 meters (57,414 feet). Initial analytical results, overlimit re-analyses and fire assay gold results continue to be received from Acme Analytical Labs and will be reported upon receipt and compilation.
Surface plan maps and modeled longitudinal sections of the Marta Este and Marta Centro zones, showing diamond drill hole pierce points from previous drilling and the current Phase V program, are available for viewing on the main Pinguino page of the Argentex web site: http://www.argentexmining.com/santacruz-pinguino.php?child=2&id=36&dec=minus. The Marta Centro long section displays zinc distribution.
About Pinguino
Argentex’s Pinguino property is located in Argentina’s Patagonia region, within the Deseado Massif of Santa Cruz province. The zinc-indium-lead-silver-gold-copper discovery at Pinguino in 2006 marked a major exploration milestone for the company. This was the first discovery of its kind in the region, unique in that it contains both silver-gold and indium-enriched base-metal mineralization in multiple zones that remain open-ended along strike and to depth. Since 2006, exploration of base-metal-rich targets has expanded beyond discoveries at Marta Centro and Yvonne and now encompasses eight mineralized veins, including the Yvonne Sur, Yvonne Norte, Sonia, Kasia, Savary and Luna veins, within an area of approximately 8.0 square kilometers (3.0 square miles).
Indium, a significant component of Argentex’s polymetallic discovery at Pinguino, is a high-value metal used in flat-panel (LCD, plasma) displays and in leading-edge solar cell technology.
Pinguino is easily accessible, situated approximately 400 meters (1,312 feet) above sea level in low-relief topography. An existing system of all-weather roads provides year-round access to the property.
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. Drilling is being conducted by Boart Longyear Connors Argentina S.A. and Major Perforaciones SA.
