Argentex intersects high-grade silver-zinc-lead 400 meters deep at Pinguino's Marta Centro zone



    Marta Este zone returns 6.74 meters of 1.65 g/t gold and 245 g/t silver

    VANCOUVER, Feb. 27 /CNW/ - Argentex Mining Corporation (TSX-V: ATX,
OTCBB: AGXM) is pleased to provide additional results from the 2008 drill
program at its polymetallic Pinguino property in Santa Cruz, Argentina.
    The latest results include assays from the deepest hole ever drilled at
Pinguino, where an intersection of 8.85 meters (29 feet) returned 92 grams per
tonne (g/t) silver and 6.55% combined lead-zinc at a depth of approximately
400 meters (1,312 feet) below the top of the Marta Centro mineralized zone. A
graphic detailing the cross section of this hole is available for viewing on
the Argentex web site:
http://www.argentexmining.com/files/Pinguino_dril_section_P269.pdf. Argentex
believes that this may be the deepest and thickest mineralized intercept
within the entire Deseado Massif of Santa Cruz province.
    "Pinguino appears to represent a strong and well-mineralized system to a
depth of approximately 400 meters (1,312 feet) and we do not see any
indications of a decrease in grades or widths at this level. The long
mineralized intersection, together with the superb silver-zinc-lead results at
this depth, confirms our original impression about the strength of the
mineralizing system and the potential for a world-class polymetallic deposit
at Pinguino," said Ken Hicks, President of Argentex. "We believe that this
deep mineralized interval has tremendous implications for the Pinguino project
and its expanding mineral potential."
    Pinguino's gold-silver Marta Este zone continues to return drill results
displaying significant gold, silver and combined base-metal values. New
results from Marta Este include 6.74 meters (22 feet) of 1.65 g/t gold, 245
g/t silver, 5.55% combined lead-zinc and 19 g/t indium.

    When drilling the deep Pinguino hole (269-08), Argentex positioned the
drill in a topographic low spot adjacent to the resistant-weathering Marta
Centro vein in order to get the best depth penetration.
    To date, Argentex has drilled a total of 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. Included
in these totals are 67 holes drilled at Marta Centro for a total of 10,125.85
meters. The Marta Centro zone has been tested to a depth of approximately 400
meters (1,312 feet) below surface. Marta Este has been drilled to a depth of
200 meters (656 feet) with 77 drill holes totaling 9,713.55 meters. Following
receipt of all remaining analytical results and interpretation, Argentex
anticipates completing its first-ever National Instrument 43-101-compliant
resource calculation for Pinguino by mid 2009.
    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 2006 discovery of
silver-indium-zinc-lead-gold mineralization at Pinguino 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. Argentex has drilled a total of
269 holes at Pinguino for a total of 30,000+ meters (98,000 feet).
    Following receipt of all remaining analytical results and interpretation,
Argentex anticipates completing its first-ever National Instrument
43-101-compliant resource calculation for Pinguino by mid 2009.
    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.
