LOS ANDES COPPER INTERSECTS 0.41% CU OVER 432 METRES INCLUDES 28 METRES GRADING 0.70% CU AND 0.01% MO (0.77% CU EQ.*)
February 27, 2008
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. Drill hole location maps and sections can be viewed at the Los Andes website www.losandescopper.com.
(*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.
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.
