Los Andes Copper Limited announced that it has engaged Coffey Mining and Alquimia Conceptos S.A. to complete a preliminary economic assessment on the Vizcachitas project located approximately 130 km northeast of Santiago, Chile in the Rio Rocin Valley. Work on the PEA has commenced and is planned for completion by July, 2013. Coffey Mining has more than 50 years of experience supplying specialist mining consulting services to the international mining industry. Coffey provides consulting and operational support and optimization services, due diligence, independent reports and a range of technical audits and studies, and is supported by a network of offices throughout the Americas, Africa, Asia Pacific, Europe and the Middle East. Alquimia is a multidisciplinary consulting and engineering company for mining projects, specialized in mining and metallurgical processes, that has conducted over 250 projects, both nationally and internationally. The NI 43-101 Preliminary Economic Assessment review provided by Coffey/Alquimia will include an updated independent resource estimate that includes the additional 5000m of drilling completed since the August 2008 AMEC resource estimate. 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.
