February 27
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 at the
Vizcachitas Project in Chile.
Highlights of the
results include Hole LAV-94, a step out hole that intersected 0.41% Cu over 432 metres, including a 28 metre
intersection grading 0.70% Cu and 0.010% Mo (0.77% Cu eq.),
LAV-98 that intersected 0.77% Cu
and 0.01%Mo (0.84% Cu Eq.) over 19.5 metres and Hole
LAV-99B that intersected 0.02% Mo
and 0.25% Cu over 340.8 metres including 0.03% Mo and 0.25% Cu over 112.8
metres ..
LAV-94 was drilled on
the western edge of section 1300NE and extends the known mineralization
over 100 metres further to the west.
LAV-98 was drilled
between historical holes V-48 and V-54 approximately 350 metres southeast
of LAV-94 on section 1300NE. The 19.5 metre interval grading 0.77% Cu
between 110.5 and 130 metres contains bornite and chalcocite mineralization
in addition to chalcopyrite. This intersection extends the higher grade
(>0.7% copper) zone, defined by previously reported intersections in
holes LAV-66, 68, 72 and 82, a further 100 metres to the north for a total
of 400 metres.
LAV-99B was drilled
about 250 metres to the northwest of LAV-98 also on section 1300NE. The
hole intersected higher than normal molybdenum grades of 0.02% Mo and 0.25%
Cu (0.4% Cu equivalent) over 340.8 metres, that included a higher grade
0.03% Mo and 0.25% Cu interval over the first 112.8 metres. This hole is
located approximately 190 metres southwest of hole LAV-93 with a previously
reported intersection of 0.057% Mo over 104 metres from 266 to 370 metres
(see news release dated December 17, 2007).
Los Andes continues to
test the limits of the Vizcachitas porphyry system in an effort to expand
the current resource. A further 6,800 metres of drilling in approximately
20 holes is expected to be completed by the end of May, at which point Los
Andes will have drilled 20,000 metres, more than the total amount of
drilling completed in the 1990s. 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 are listed 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. At a 0.4% cutoff, indicated resources total 144 million
tonnes grading 0.52% copper and 0.015% molybdenum and inferred resources
total 211 million tonnes grading 0.46% copper and 0.016% molybdenum 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 ..
