Argentex high-grade silver-gold drill results advance Pinguino towards 43-101 resource report, continue to expand property's overall mineral potential



    VANCOUVER, April 6 /CNW/ - Argentex Mining Corporation (TSX-V: ATX,
OTCBB: AGXM) is pleased to announce additional results from the 2008 drill
program at its polymetallic Pinguino property in Santa Cruz, Argentina. The
latest findings include assays from 13 new drill holes testing four separate
mineralized zones, including a 2.5-meter (8.2-foot) intersection that contains
5.32 grams per tonne (g/t) gold, 29 g/t silver and 1.5% combined lead-zinc. A
deeper hole drilled in the same vein returned 4.96 meters (16.2 feet) grading
2.17 g/t gold, 314 g/t silver, 2.13% lead and 4.76% zinc. A relatively
untested vein, Marta Noroeste, returned 1.35 meters (4.41 feet) grading 6.99
g/t gold and 773.5 g/t silver.
    Additional findings include overlimit zinc results and previously
reported high-grade gold samples that have been re-assayed using a metallic
screen technique to confirm the presence of native gold.
    "There are a number of intersections with significant silver and gold
values within the 15 mineralized zones drill tested to date at Pinguino," said
Ken Hicks, President of Argentex. "Several intersections returned significant
gold values that have since been reanalyzed using a metallic screen, which
provides a more accurate determination of gold values when there is native
gold present. The two distinct styles of mineralization at Pinguino, which
contain precious metals and base metals enriched with indium, continue to
expand the overall mineral potential at Pinguino."
    Argentex has now received and compiled the majority of its analytical
results from the 2008 program at Pinguino. According to Acme Labs, the last
set of results for the Pinguino project should be ready within approximately
two weeks. At that time, the company intends to transfer its complete dataset
of analytical results, drill hole logs, surface geochemistry, geophysics,
core-specific gravity measurements and preliminary mineralogical studies to an
independent engineering firm for the purpose of beginning Argentex's
first-ever National Instrument 43-101-compliant resource calculation, which is
scheduled for completion during Q2 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 were collected and submitted to Acme Analytical Laboratories for
analysis. Some overlimit analyses of zinc, lead and silver are still 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 the initial
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). 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 (31,868 feet).
    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.

    ABOUT ARGENTEX:

    Argentex Mining Corporation is a junior mining exploration company with
significant holdings in the Patagonia region of Argentina. It holds an
undivided 100% interest in the mineral rights to the Pinguino property. In
total, the company owns 100% mineral rights to more than 40 properties with
approximately 405,987 acres (163,477 hectares) of prospective land located in
the Santa Cruz and Rio Negro provinces of Argentina. Shares of Argentex common
stock trade under the symbol AGXM on the OTCBB and on the TSX Venture Exchange
under the symbol ATX.
    Exploration on the Pinguino property is being conducted under the
supervision of Mr. Kenneth Hicks, P.Geo., Argentex's President and a
"qualified person" as defined by Canada's National Instrument 43-101. Mr.
Hicks has read and approved the contents of this release.

forward-looking statements. Forward-looking statements are based on current
facts and analysis and on forecasts of future results, estimates of amounts
not yet determined and assumptions of management. Forward-looking statements
in this news release include statements about the company's belief that the
two distinct styles of mineralization at Pinguino continue to expand the
overall mineral potential at Pinguino and that Argentex will transfer its
complete dataset to an independent engineering firm for the purpose of
beginning a National Instrument 43-101-compliant resource calculation for
Pinguino which is scheduled for completion during Q2 2009. Actual results may
differ materially from those currently anticipated due to a number of factors
beyond the Company's control. These risks and uncertainties include, among
other things, competition for qualified personnel and risks that are inherent
in Argentex's operations including the risk that the Company may not find any
minerals in commercially feasible quantity or raise funds sufficient to
prosecute its exploration plans. These and other risks are described in the
Company's Annual Report on Form 10-K and other filings with the Securities and
Exchange Commission.
