    Cana Brava is located in south-central Ecuador in Loja Province. Results strongly suggest that a porphyry system(s) lie at shallow depth below the Soroche and Quebrada Caña Brava targets with peripheral higher level Intermediate sulphidation veins at Soroche Norte. So far, 4 mineralized zones have been identified and a phase 1 drilling program of 3,200m is proposed. Cornerstone is completing work on an environmental impact assessment (EIA) for Caña Brava, approval of which is a condition to obtaining the environmental license to drill the property.
