Local geology comprises predominantly continental sediments ranging from NeoProterozoic to Lower Paleozoic in age, the latter being in part weakly metamorphosed by Tertiary granitic and andesitic intrusions. The copper (Cu) and silver (Ag) mineralization at Plata Dorada is structurally controlled and consists of polymetallic quartz sulphide veins averaging 0.5 to 1.5m wide.
Mineralization is dominated by Cu and Ag with historic sampling ranging from 0.3 to 8.7% Cu, and 70 g/t to over 1500 g/t Ag. Gold (Au) is present in trace amounts. There are two zones of veins with multiple vein sets on the property with distinct orientations: North West and North-North-East. Dips are between 45o to 82o and individual strike lengths are in excess of 100 m.
