Minera Andes San Jose project drilling hits 1.86 ounces per ton gold and 163 ounces per ton silver at the Frea vein



    TSX: MAI
    NASD-OTCBB: MNEAF

    SPOKANE, WA, Sept. 6 /CNW/ - Minera Andes Inc. (TSX: MAI and US OTC:
MNEAF) is pleased to announce the initial results of the ongoing 2007
exploration program at its San José mine in the start-up of production in
southern Argentina. The highest grade intercept from this drilling campaign is
in hole SJD-341 that encountered 58.66 g/t (1.86 ounces per tonne - opt) gold
and 5,081 g/t (163 opt) silver over 0.68 meters.
    Phase one of the planned 38,000 meter exploration drilling program
announced earlier in 2007 at San José was completed in July. A total of
8,310 meters were drilled in 31 core holes with assays received for the first
fourteen drill holes listed in the table below. Assays are pending on the
remaining drill holes. The next phase of drilling has started and will focus
on the open ended Frea vein and the targets to the west in the Odin and Ayelen
areas.
    The Frea vein is located 2 kilometers northwest of the Huevos Verdes
vein, and both veins are being mined on several levels. Reserves at the Frea
vein are currently delineated over a strike length of about 575 meters and to
a depth of approximately 350 meters below the surface. The new drilling in
2007 extends the known mineralization another 200 meters along strike - a 35%
increase.
    The initial exploration drilling concentrated on the northwest and
southeast extensions of the Frea vein outside of the area currently being
mined. Significant drilling results include SJD-333 that encountered 4.57 g/t
gold and 744 g/t silver over 0.70 meters of high grade mineralization
225 meters southeast of the defined reserves at the Frea vein. Drill hole
SJD-341 encountered 2.13 meters containing 20.84 g/t gold and 1,729 g/t silver
about 125 meters southeast of the Frea reserves and hole SJD-336 encountered
4.99 meters containing 8.92 g/t gold and 821 g/t silver about 25 meters
southeast of the current Frea reserves. Hole SJD-346 encountered 1.35 meters
containing 5.80 g/t gold and 563 g/t silver 75 meters northwest of the current
reserves. The mineral reserves indicate the Frea vein is an open-ended
mineralized silver/gold vein that averages about 2.7 meters in width. All of
the new results from the drilling are listed in the table below.
    Allen Ambrose, president of Minera Andes, said: "The exploration drilling
at the San José project continues to expand the project. The Frea vein is
revealing significant potential to expand the reserves and mine life of the
project."
    Minera Santa Cruz S. A., the joint venture corporation co-owned by Minera
Andes (49%) and Hochschild Mining plc. (51%) owns the producing San José
property. The discovery of new high-grade silver/gold extensions to veins such
as Frea represents additional mineralization that may add to the current
reserves under production at the project. These discoveries also indicate the
large mineral potential of the San José property where more than 40 kilometers
of vein trend target is currently known to exist, of which less than
15 percent has been explored in detail.

    (*) All of the drill holes are drilled at minus 50 degrees. Drill holes
    SJD-331, 332, 337 and 360 failed to reach the targeted depth and were
    abandoned. True thickness of the vein is undetermined.
    

    Assay results for the drilling were reviewed by Brian Gavin, Minera
Andes' vice president of exploration, who is an appropriately qualified person
as defined by National Instrument 43-101. All samples were collected in
accordance with industry standards. Splits from the drill core samples were
submitted to Alex Stewart Assayers, Argentina, S.A., in Mendoza, Argentina,
for fire assay and ICP analysis. Accuracy of results is tested through the
systematic inclusion of standards, blanks and check assays.

    Minera Andes is a gold, silver and copper exploration company working in
Argentina. The Corporation holds about 410,000 acres of mineral exploration
land in Argentina including the co-owned San José silver/gold mine that has
started initial production. Minera Andes is also exploring the Los Azules
copper project in San Juan province, where an exploration program is underway
to define a resource. Other exploration properties, primarily silver and gold,
are being evaluated in southern Argentina. The Corporation presently has
166,700,767 shares issued and outstanding.

José mine will be successfully increased, that resources and reserves at the
San José mine will be increased or that Minera Andes will successfully raise
the funds necessary to maintain its interest in the San José mine. Risks and
uncertainties that could cause results or future events to differ materially
from current expectations expressed or implied by the forward-looking
statements include, but are not limited to, factors associated with
fluctuations in the market price of precious metals, mining industry risks,
risks associated with foreign operations, the state of the capital markets,
environmental risks and hazards, uncertainty as to calculation of mineral
reserves and other risks. Reference is made to the risk factors and

project data or the adequacy or accuracy of this release.

    Cautionary Note to U.S. Investors:

    The United States Securities and Exchange Commission (the "SEC") permits
mining companies, in their filings with the SEC, to disclose only those
mineral deposits with "mineral reserves" that a company can economically and
legally extract or produce. We use certain terms in this press release, such
as "mineral resources", that the SEC guidelines strictly prohibit us from
including in our filings with the SEC.
