Argentex: Silver dominates 2010-2011 exploration program at Pinguino, Santa Cruz, Argentina

Dec 15, 2010, 09:00 ET from Argentex Mining Corporation

VANCOUVER, Dec. 15 /PRNewswire/ - Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) is pleased to announce that its 2010-2011 exploration program has commenced in Santa Cruz province, Patagonia, Argentina.  The proposed US$4.0-million program is scheduled to include 17,000 meters of drilling.

The program will focus on the high-grade silver intersections discovered in reconnaissance drilling completed in 2010 in areas such as Tranquilo, Tranquilo Sur and Luna.  These veins are all wide open and located within Pinguino's Tranquilo Trend, a prominent regional structure that crosscuts the property over 11 kilometers.  Previously published results in these areas include Hole P349-10, which returned a thick intersection of high-grade silver mineralization containing 6.0 meters of 2,428 grams per tonne (g/t) silver and 0.22 g/t gold, Hole P358-10 containing 4.6 meters of 313 g/t silver and 0.16 g/t gold, and Hole 308-10 containing 6.40 meters of 486.6 g/t silver and 1.91 g/t gold.

Drilling will initially target these high-grade silver zones from surface to a depth of approximately 50 meters. Our geological modeling predicts a precious-metal enrichment zone near surface. Previously published metallurgical results show the mineralization in this near-surface oxidized zone to have a simple mineralogy and excellent recovery. Additional drill testing within this program is designed to test the deeper extensions of this mineralization.

More than 50 individual veins have so far been discovered at Pinguino, with a combined strike length in excess of 75 line kilometers.  Only a small percentage of Pinguino's entire system of veins and known targets has been drill tested to date.

"Our goal with this program is to expand the near-surface silver mineralization by approximately 70%," said Ken Hicks, President of Argentex. "As many of the known high-grade silver intersections were only recently discovered, we are excited about the potential to expand these targets."

Pinguino Drilling

Argentex proposes to drill a total of 17,000 meters using a combination of reverse-circulation drilling (13,500 meters) to expand near-surface oxidized silver-gold mineralization and diamond drilling (3,500 meters).  The 2010-2011 program is also scheduled to include 12,000 meters of trenching.

Highlights of the 2009-2010 drill program at Pinguino show a very successful first test of silver-gold mineralization and includes intersections such as:

About Pinguino

Argentex's Pinguino property is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province.  Recent high-grade silver discoveries within newly tested structure of the district scale vein system at Pinguino show potential for the development of a significant silver resource.

The Deseado Massif is an active region of mining with four precious metal mines currently in production. Advanced exploration as well as early-stage projects are also well established in this area.

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.
