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 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.
