New Argentex silver-indium-zinc-lead drill results and overlimits further expand mineralization in four zones at Pinguino



    VANCOUVER, Feb. 19 /CNW/ - Argentex Mining Corporation (TSX-V: ATX,
OTCBB: AGXM) is pleased to announce additional drill results from the 2008
program at Pinguino, the company's polymetallic property in Santa Cruz,
Argentina. The latest findings include overlimit analytical results, which
significantly expand previously published intervals. New intervals include an
8.6-meter (28.2-foot) intersection at Marta Este that returned 164.7 grams per
tonne (g/t) silver, 6.23% combined lead-zinc and 3.9 g/t indium. Hole P163 at
Marta Centro returned 13.52 meters (44.36 feet) of 50.6 g/t silver, 9.52%
combined lead-zinc and 46.4 g/t indium.
    Both the overlimits and the new results expand intervals of
mineralization in their respective zones.

    Results

    Table 1 shows the expansion of mineralization in two previously published
drill holes (see press release dated September 25, 2008) at Marta Norte and
Yvonne Sur. Overlimit analytical results have been incorporated.

    Argentex has drilled 269 holes at Pinguino, testing 15 epithermal veins
in the process, for a total of 30,000+ meters (98,000 feet). The robust
mineralized system remains open in all directions. Following receipt of all
remaining analytical results and interpretation, Argentex anticipates
completing its first-ever National Instrument 43-101-compliant resource
calculation for Pinguino during the current year.
    During the 2007-2008 exploration program, Argentex completed
approximately 20,782.9 meters (68,185 feet) of HQ diamond drilling at Pinguino
using two independent drill contractors. A total of 15 base-metal and
precious-metal veins were tested in 151 new HQ diamond drill holes.
Approximately 7,000 core samples have been collected and submitted to Acme
Analytical Laboratories for analysis. Overlimit analyses of zinc, lead and
silver are pending. Additional results will be reported upon receipt and
compilation.

    About Pinguino

    Argentex's Pinguino property is located in Argentina's Patagonia region,
within the Deseado Massif of Santa Cruz province. The
silver-indium-zinc-lead-gold 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. This mineralization is contained 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 15 drill-tested veins from more
than 35 veins mapped on the property to date.
    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 thin-film 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 in 2008 was conducted by Boart Longyear Connors
Argentina S.A. and Major Perforaciones SA.
