THE SANTA ANA PROJECT
The Santa Ana project consists of one mining concession covering an area of 669 hectares, located in the department of Tolima, Colombia. The property is 100% owned by OGC.
The Property covers the core of the historical Mariquita silver district, one of Colombia’s most prolific colonial silver mining camps with production dating back to the 16th century and continuing until at least 1914. The Santa Ana Mine Group was one of the more important producers in the district.
Six vein zones have been interpreted which taken together accumulate to over 6 km of total strike. Each zone contains a package of several parallel veins. Veins mapped to date are north-south, but locally east-west veins are observed, and some historic reports indicate production from both vein-trends.
The veins are interpreted to be a composite of early polymetallic gold-silver orogenic thrust-fold related and later epithermal open-space veins in highly deformed Paleozoic schist, quartzite and gneiss of the Cajamarca Formation.
