Editorial on Arizona Sonoran's First Nuton Test Results

George Ogilvie of Arizona Sonoran Copper joined us for his corporate editorial comments on the first preliminary results form Rio Tinto's Nuton technology. Primary sulphide extraction ranges from 61% to 82% based on 5 columns, including 2 early cycle columns returning 83% and 61%, 2 mid-cycle columns above 70% and 1 with lower extraction based on biotite content. Nuton is currently reassessing the additives for this low extraction column to address future biotite exposure, which accounts for approximately 1-2% of the Cactus West deposit in the primary zone.
