The main mineralized zones of the Santana project exhibit strong, low-sulfidation alteration characterized by pervasive and structurally controlled sericite-quartz-calcite alteration with associated disseminated iron oxides, quartz vein stockworks and clay alteration. Numerous historical pits and small underground workings are evident in the area. Gold and silver mineralization is controlled by both lithologic and structural features and presents itself at the Nicho and Nicho Norte zones as mineralized elliptical sub-vertical hydrothermal breccias that are 300-500  m in diameter and hosted in stocks and batholithic intrusions.

The breccias typically outcrop at surface. As part of its ongoing exploration activities the Company is engaged in a systematic review of the entire project area to identify additional surface expressions with the potential for resource definition.
