Latest Information December 20, 2005 Completed phase two drilling consisting of eleven holes to test several target areas within and around the intrusive complex centered on detailed geologic mapping, rock and soil sampling, and data from multiple geophysical surveys(ground, IP polarization and resistivity.) Targets are centred about a subvolcanic intrusive centre and associated high-sulphidation epithermal gold-silver and base metal system exposed over two square kilometres. Multiple stages of mineralization and alteration are evident in the core. Mineralizing events include 1) a gold-only pulse; 2) gold and silver; and finally 3) a base- and precious-metal phase. Low- level disseminated and/or fracture-controlled gold and silver concentrations have been detected over significant widths in all areas tested. All mineralizing events are associated with high level or subvolcanic feldspar porphyry intrusions of andesitic to dacitic composition. Late stage base- and precious- metal bearing veins locally crosscut earlier mineralized zones. The veins occur as swarms, fracture fillings and stockworks and locally contain significant gold, silver, zinc, lead and copper. Future work includes 3-D modelling of the distribution of the various metals and mineralization styles hosted at Calorco to identify any areas warranting additional exploration.
