(*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 Cu eq% =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, President
and CEO of Los Andes Copper, stated: �We continue to be pleased with the
results of drilling at Vizcachitas, especially the 209.2 metre
intersection in LAV-131 which is the best drilled by Los Andes on the
project to date. This intersection is particularly significant, as the hole
is collared close to the southern limit of known mineralization. Los Andes
continues to drill with the aim of increasing the already significant
resource recently announced for the Vizcachitas deposit.�
Holes LAV-125, 126 and
LAV-131 were all collared on Section 800NE. Holes LAV-125 and
LAV-126 both intersected porphyritic andesite at the top and bottom of the
holes, separated by an interval of tonalite. Higher grade intervals of 0.79% Cu and 0.012% Mo (0.87% Cu eq.)
in hole LAV-125, and 0.67% Cu and
0.035% Mo (0.90% Cu eq.) in hole LAV-126 are associated
with biotite-magnetite alteration and the presence of chalcocite and
bornite.
Hole LAV-131, collared 200 metres southeast
of LAV-126, intersected a thick section of andesite breccia in addition to
the porphyritic andesite and tonalite intersected in LAV-125 and 126. The
highest grades were found in the porphyrtitc andesite and andesite breccia
and coincide with the presence of chalcocite down to about 100 metres. This
hole is located approximately 100 metres southwest of previously
announced hole LAV-80 that intersected 0.72% Cu and 0.014% Mo (0.82% Cu
eq.) over 40 metres.
Hole LAV-127 was
drilled on Section 1300NE at the eastern margin of the known
mineralization. Despite returning low copper and molybdenum values,
disseminated chalcopyrite and pyrite were intersected over the entire
length of the hole hosted by quartz sericite altered andesite, tonalite and
diorite porphyry.
Hole LAV-128 was drilled on Section 1000NE and intersected porphyritic
andesite over the entire length. Chalcopyrite is the dominant copper
mineral, with weak chalcocite development over the first 100 metres.
Hole LAV-129 was drilled on Section 1300NE approximately 100m southeast
of previously announced Hole LAV-99B that intersected 0.029% Mo over 136.8 metres. Hole
LAV-129 also intersected higher than normal molybdenum values, grading
0.029% Mo and 0.31% Cu (0.50% Cu eq.) over the entire 246.8 metres
including 14 metres grading 0.133% Mo and 0.26% Cu (1.15% Cu eq.)
between 176 and 190
metres.
Results from these infill holes should increase the indicated resources
recently announced as 515 million tonnes grading 0.39% copper and 0.011%
molybdenum at a 0.30% Cu eq. cutoff (see news release dated July 16, 2008)
when the resource is updated. Based on drilling to date, the Vizcachitas
mineralization remains open to the south, east and at depth and drilling
continues in order to define the limits of the mineralization. AMEC is
currently undertaking a scoping study/initial economic assessment of the
Vizcachitas deposit, with results anticipated in October.
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 giant copper-molybdenum porphyries Rio
Blanco-Los Bronces, Los Pelambres and El Teniente. Based on 35,255 metres of
drilling in 130 diamond drill holes, the project contains an indicated
resource of 515 million tonnes grading 0.39% copper and 0.011% molybdenum
and an inferred resource of 572 million tonnes grading 0.34% copper and
0.012% molybdenum at a 0.30% copper equivalent cutoff. Additional
information about the Vizcachitas Project is available on our website at www.losandescopper.com .
