El Sauzal is an epithermal deposit of high sulfidation defined by mega breccias and volcanic event flows. It is a disseminated oxide ore body of high-grade and gold mineralization associated with advanced argillic alteration. Gold is largely disseminated within the ore body and less commonly found along fractures where gold is visible. The oxide ore body is underlined by sulphides with little exploration. More than 60% of the ore—and most high-grade ore—is found in transitional quartz-kaolinite rock that is peripheral to vuggy quartz.
