Minera Andes Exploration program increases the size of the Los Azules porphyry copper target

    TSX: MAI

    SPOKANE, WA June 27 /CNW/ - Minera Andes Inc. (TSX: MAI; US OTC: MNEAF)
is pleased to report that the final results from core holes drilled during the
2007-2008 exploration field season at the Los Azules porphyry copper project
confirm that the copper target is open to the north. Several positive
indicators including hole AZ-08-37A drilled at the northern limit of this
seasons drilling, geologic mapping, and historic drilling indicate that the
copper target at Los Azules extends another 3 kilometers to the north of the
drilling completed this field season (see URL for map:
    As previously reported, hole AZ-08-37A encountered 112 meters of 0.98 %
copper within a larger zone of 217 meters of 0.77 % copper. This hole
represents the largest interval of primary copper mineralization identified on
the property to date. It extends the known mineralization an additional
400 meters to the north and is the deepest hole drilled to date on the
property by Minera Andes, suggesting that the limits of the copper system have
not yet been defined. Also, additional check assay work preformed as part of
the geologic studies underway showed hole AZ-08-41 to contain 152 meters of
0.81 percent copper within a zone of 236 meters of 0.62 percent copper (this
represents an increase of 72 percent and 55 percent respectively over the
previously reported copper results).
    Allen Ambrose, president of Minera Andes said "The success we have had in
the northern limits of our exploration program combined with historic drilling
on the property further north indicate significant potential for target
    The exploration program at Los Azules is designed to define an inferred
resource and provide sufficiently detailed engineering and technical
information to allow the completion of an economic scoping study (a
Preliminary Assessment as defined by NI 43-101) of the property by the fourth
quarter of this year. Due to the expansion of the copper target at Los Azules,
planning for next season's field program starting in November of this year is
underway to explore the 3 kilometers of target to the north of the scoping
study area.
    The prospective area north of our current drilling contains several drill
holes from a 1998-1999 precious metals exploration program by Battle Mountain
Gold (see URL for map:
http://files.newswire.ca/530/ProyectLosAzules07-08.doc). These holes
encountered geology and anomalous copper mineralization similar to that found
in recent drilling by Minera Andes to the south, providing some insight into
the potential of the area to host additional porphyry copper mineralization.
    Minera Andes is advancing the Los Azules project under an option
agreement (see news release dated November 14, 2007) with Xstrata Copper, one
of the commodity business units within Xstrata plc (London Stock Exchange:
XTA.L and Zurich Stock Exchange: XTRZn.S). The scope and size potential of the
project increased dramatically in 2006 when the Minera Andes drilling
discovered a near surface high-grade area of copper mineralization, when
AZ-06-19 encountered 221 meters of mineralization averaging 1.62% copper that
was 200 meters from hole AZ-06-20 containing 173 meters of 1% copper. Drilling
in several holes ended in copper mineralization, including two holes that
bottomed in high-grade copper over 1%.
    During the last few years, more than half the drilling to define a copper
resource has been completed and drilling this field season was over the known
area of leachable (chalcocite) and sulfide (chalcopyrite) copper
mineralization as currently defined. The area drilled covers approximately
2.5 kilometers by 0.9 kilometers within the enriched copper target currently
identified at Los Azules that is about 3.3 kilometers long and 0.9 kilometers
wide. Holes were drilled at a nominal grid spacing of 200 meters east-west and
400 meters north-south. Where needed, select infill holes were drilled on the
200 meter north-south grid lines.
    All results have been reviewed by Brian Gavin, Minera Andes' vice
president of exploration, 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 sample pulp
preparation and to ALS Chemex Laboratories.

    Minera Andes is a gold, silver and copper exploration company working in
Argentina. The Corporation holds about 304,000 acres of mineral exploration
land in Argentina including the 49% owned San José silver/gold mine that has
recently commenced production. As discussed above, Minera Andes is 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 189,439,935 shares issued and outstanding.
