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

December 15, 2010

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

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.
