Gold targets picked at Ubina

In southwestern Bolivia, exploration managers have selected three targets at the Ubina property of COMOSA, a unit of Takla Star Resources (ASE).

Mintec, the Bolivian exploration contractors managing the work for Takla Star, outlined the three targets after completing reconnaissance mapping and surface sampling in a 28-sq.-km area underlain by Cretaceous sedimentary rocks that are intruded by Tertiary stocks and volcanic feeders. The area has undergone small-scale production of tin, silver and tungsten, some of which dates to Spanish colonial times.

One showing, called the Plateau prospect, contains an altered sequence of sandstones and shales. The sandstone unit is mineralized, and channel samples had a weighted average gold content of 0.03 oz. per ton.

The two other showings are subsidiary zones of vein-type gold mineralization which Takla Star geologists interpret as feeders stratigraphically below the Plateau mineralization.

Reconnaissance exploration of the company’s other nine Bolivian projects is believed to be under way.
