(*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, President
and CEO of Los Andes Copper commented as follows: “We are very
encouraged by the continued success of the drilling at Vizcachitas, and
especially by the higher grade mineralization that we continue to intersect
in the southwest portion of the drilled area.”
Discussion of
Results
LAV-89 was drilled on Section 1100NE
and intersected moderately quartz-sericite altered breccia to 47.1 metres and
granodiorite between 47.1
metres and the end of the hole. The zone of higher
grade mineralization outlined in LAV-68, LAV-72 and LAV-82, is now extended
100 metres
to the northwest by the intersection of 92 metres
grading 0.70% Cu and 0.023% Mo (0.85% CuEq.) including 0.88% Cu and 0.021%
Mo (1.02% CuEq.) over 38
metres in this hole.
LAV-90 was drilled 200 metres to the
northwest of LAV-89 and intersected variably altered andesite to 270 metres followed
by weakly altered tonalite and granodiorite to the end of the hole. This
hole also intersected a higher grade interval grading 0.70% Cu over
30 metres
between 32 and 36
metres.
LAV-91 was drilled on Section 1200NE
and intersected mostly granodiorite with weak quartz-sericite alteration
overprinting weak biotite alteration. The hole was well mineralized along
its entire length and also intersected a higher grade interval grading 0.71%
Cu and 0.012% Mo (0.79% CuEq.*) over 54 metres.
LAV-92 was drilled on Section 900NE and
intersected granodiorite to 81.45 metres followed by alternating
diorite and andesite to the end of the hole.
LAV-93 was drilled on Section 1300NE
and intersected andesite to 236 metres followed by alternating
granodiorite and tonalite with another andesite interval between 294 and 356 metres. This
hole also produced one of the best molybdenum intersections so far in the
recent drilling programs grading 0.057% Mo over 104 metres.
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.
