El Alto - an IOCG-Type Cu-Au-Ag Prospect

• Cu-Au-Fe mineralization at El Alto is characterized as an Iron-Oxide Copper Gold (“IOCG”) ore deposit model. Based on their large tonnage potential and polymetallic nature (in the order of 250 million to 1 billion tonnes of 1% Cu with appreciable amounts of by- product Au, Co, Ag, U, Zn, Mo, REE) the IOCG class of ore deposits represents an attractive exploration target.
• El Alto lies at the southern extremity of the Mesozoic Iron Belt that stretches from north of Santiago to the city of Antofagasta in the north along the Coastal Cordillera of  Chile (~ 1,200 km).
• The Chilean Iron Belt represents one of the most prospective   IOCG provinces in the world and hosts several world class copper deposits including Candelaria (470 Mt @ 0.95 % Cu & 0.22 g/t Au), Mantos Blancos (400 Mt @ 1% Cu), Manto Verde (350 Mt @ 0.75% Cu), and El Soldado (200 Mt @ 1.5% Cu).
• Results of the Company’s recently completed mapping and sampling confirm the polymetallic nature of the El Alto mineralised breccia body.  Highlights include a length weighted average grade chip sample of 1.68% Cu and 0.59 g/t Au over 14.6 metres, including 2.81% Cu and 1.21 g/t Au over 6 metres, and composite chip samples and grab samples from individual breccia seams ranging from 1.39% - 11.55% Cu, 0.96 g/t - 4.0 g/t Au, and 23.9 ppm - 70.3 ppm Ag.
• The El Alto FeOx–Cu–Au mineralization is characterized by linear bodies of multiphase hydrothermal/tectonic breccias cross-cutting a thick sequence of skarnified Lower Cretaceous volcaniclastic sequence intruded by a basin - parallel belt of granitoids of Lower to Middle Cretaceous age.
• Chalcopyrite - pyrite bearing, specularite - magnetite - amphibole rich breccias exhibiting typical Cu - Au (+/- Ag, Co, Zn, Bi, Ni, W) IOCG geochemical signature.
• Exploration activities are underway and will include diamond drilling which will start in Q1, 2011. The geophysical data, collected to date in addition to the detailed geological and structural mapping and lithogeochemical sampling completed have led to the development of planned 5000 m drill program.
