Bolivar State, Colombia

Southern Bolivar has been recognized for decades as an important mining district. Located on the Serrania de San Lucas, northern foothills of the Cordillera Central of Colombia and the geological continuity of the mining districts of northeastern Antioquia, becomes a “potential gold mine” for serious exploration companies to invest in the region.

The four main mining areas are: (map located below)

Tiquisio Monte Cristo – According to the latest census there may be about 600 mines and over 3,000 people working.  Gold vein mineralization are presented with thicknesses ranging from 0.24 m to 4.0 m. With structural trend N50 – 70 E towards the SE. The veins maybe in lengths in the course of several kilometres and average tenors ranging from 0.20 g/t to 65.0 g/t gold.  According to the information available in the area, reported regionally important geochemical anomalies of Au, Ag, As, and Cu exist.

San Pedro Frio – In this centre there may be about 1,000 mines and about 5,000 people working. According to data published for this area, gold vein structures up to 5 m thick exist and 25 m wide. Geochemical results for gold content on the oxiidation zone were as high as 74 g/t Au and up to 36.6 g/t Au in the sulphides.

Santa Rosa Canelos – In this area there are about 300 mines.  The main mineralogical composition is quartz viens and massive sulphides. (pyrite, sphalerite and some galena and chalcopyrite) From the correlation of information form mines in the area, most of the veins have lengths in the course of several kilometres and average tenors ranging from 0.6 g/t Au to 42.77 g/t Au.

Guamoco – In this area there are 2,000 mines and 10,000 to 15,000 people working in the development of these mines. Quia Resources is working a project in this area.
