Vancouver, BC - Los Andes Copper Ltd. ("Los Andes", or the
"Company", TSX Venture Exchange: LA) announces results from a
further eight holes of the phase II drilling program currently underway at
the Vizcachitas Project in Chile.
Highlights of the results include Hole LAV-108, drilled in the
southwest, that intersected 0.57%
Cu over 218 metres, including a 16 metre, near surface intersection grading
0.88% Cu and 0.010% Mo (0.95% Cu eq.), and Hole LAV-109
that intersected 0.41% Cu and
0.015% Cu (0.51% Cu eq.) over 198 metres including 0.50% Cu and
0.026% Mo (0.67% Cu eq.) over 68 metres .
LAV-107 and 107A are infill holes drilled on section 900NE. Hole LAV-107
had to be stopped due to ground problems prior to reaching the target depth,
so Hole LAV-107A was drilled at the same collar. Both holes encountered
predominantly chalcopyrite mineralization with traces of chalcocite,
bornite, covellite and molybdenite.
LAV-108 was drilled 100 metres southwest of Hole LAV-107 on section
800NE. The near surface high grade intersection occurs in weak to moderate
biotite-magnetite altered andesite containing disseminated chalcopyrite and
chalcocite mineralization and traces of molybdenite in fractures.
LAV-109 is an infill hole drilled on section 1100NE on the east side of
the Rosin River. The 68 metre interval grading 0.50% Cu and 0.03% Mo occurs
in biotite-magnetite altered andesite containing chalcopyrite and
chalcocite.
Step out holes LAV-102, LAV-103 drilled in the southeast, and step out
hole LAV-104 drilled in the southwest, while containing only traces of
copper mineralization, still encountered significant alteration in the form
of pyrite-quartz-sericite indicating the persistence of the porphyry system
in these areas.
Los Andes continues drilling with two rigs at Vizcachitas and plans to
complete a further 5,000 metres of drilling by the end of May. An updated
resource calculation, using results from both historical and recent
drilling, will be completed following this phase of drilling.
A summary of results from the eight holes is given in the table below.

(*Copper equivalent is calculated for Mo values greater than 0.01%
using US$1.50/lb Cu and US$10.00/lb Mo according to the formula CuEq% =Cu%
+ (Mo% x 10.00/1.50) and is not adjusted for metallurgical recoveries or
net smelter return which remain uncertain and are assumed to be 100%).
Roger Moss, Ph.D., P.Geo, is the qualified person as defined by National
Instrument 43-101 for the Vizcachitas Project. Logging, sampling and
splitting of the drill core is conducted at the Vizcachitas site by
independent consultants Geologica LTDA. under the direct supervision of
geologist Ramon Fam. Samples are securely transported by Geologica staff to
the SGS Laboratory in Santiago Chile and analyzed for copper and molybdenum
by atomic absorption following a three acid digestion. Dr. Moss and Mr. Fam
have visited the laboratory and are satisfied that the sample preparation
and analytical procedure is consistent with standard industry practice. Los
Andes routinely inserts standards, duplicates and blanks into the sample
stream and sends 5% of sample rejects to Actlabs for check analysis.
About Vizcachitas
The Vizcachitas Project offers potential for a low strip, open pit
operation in an area of low elevation with excellent infrastructure,
including water and power in central Chile. The Vizcachitas deposit occurs
in the same metallogenic belt as the large copper-molybdenum porphyries Rio
Blanco-Los Bronces, Los Pelambres-El Pachon and El Teniente. Based on 68
drill holes previously completed by General Minerals Corporation and Placer
Dome, the project contains an indicated resource of 232 million tonnes
grading 0.46% copper and 0.014% molybdenum and an inferred resource of 619
million tonnes grading 0.38% copper and 0.013% molybdenum at a 0.30% copper
cutoff as detailed in the NI43-101 compliant technical report of
A.C.A. Howe International Limited
dated February 7, 2007. The technical report, as well as additional
information about the Vizcachitas Project is available on our website at www.losandescopper.com .
