Drilling Update

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 NI 43-101 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.
