LOS ANDES COPPER INTERSECTS 26 METRES GRADING 0.95% CU AND 0.02% MO (1.08% CU EQ.*) WITHIN 209.2 METRES GRADING 0.68% CU AND 0.014% MO (0.77% CU EQ.*)
August 6, 2008
Vancouver, BC – Los Andes Copper Ltd. ("Los Andes", or the "Company", TSX Venture Exchange: LA) announces results from the latest seven holes of the ongoing drilling program at the Vizcachitas Project in Chile.
Highlights of the results include Hole LAV-125 that intersected a near surface interval grading 0.79% Cu and 0.012% Mo (0.87% Cu eq.*) over 20 metres, Hole LAV-126 that intersected 0.55% Cu and 0.03% Mo (0.75% Cu eq.*) over 50.85 metres including 0.67% Cu and 0.035% Mo (0.90% Cu eq.) over 18 metres and LAV-131 that intersected 0.68% Cu and 0.014% Mo (0.77% Cu eq.*) over 209.2 metres including 0.71% Cu and 0.014% Mo (0.80% Cu eq.*) over 129.2 metres and 0.95% Cu and 0.02% Mo (1.08% Cu eq.) over 26 metres.
A summary of results from the seven holes is given 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 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.
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.
