Exploration and Mining in Colombia - Gold Exploration in Colombia, Gold Mining in Colombia
Regarded as largest gold producer in Latin America in earlier days, Colombia has over 80 million ounces of historic gold production to its credit. The civil unrest conditions in Colombia prevented it from experiencing the exploration and investment boom of the 1980s and 1990s due to which till now there are a number of favorable mining areas in Colombia that are left unexplored. These vast unexplored gold deposits make Colombia an ideal location for gold exploration and mining.

Gold exploration and mining in Colombia:

Seeing the vast potential for exploration and mining in Colombia some mining companies in Colombia have started exploration activities for gold mining development in Colombia. The rocks in which gold metal compounds are identified are said to possess gold mineralization. Gold exploration in Colombia is the activity undertaken by mining companies in Colombia for finding out these deposits of rocks containing gold mineralization which can be mined for production of gold. Yarumalito, El-Dovio, Rio Negro, Anori, Venecia are some of the major unexplored areas of Colombia that have vast potential for gold exploration and mining. Located in the most famous mining district of Colombia, region of Yarumalito hosts vast number of productive gold mineral deposits. Gold-copper porphyry type mineralization, contact related mineralization in sediments intruded by the porphyry system and high-grade, structurally controlled mineralization are the three types of gold mineralization at Yarumalito make it an ideal location for gold mining in Colombia.

Hosting polymetallic mineralization of gold, silver, copper and zinc in a volcanogenic massive sulfide (VMS) deposit, region of El Dovio provides best opprtunity to apply modern techniques of surface mining and underground mining for mining in Colombia. The gold mineralization at El Dovio occurs as polymetallic, structurally controlled veins within broad zones of stockwork mineralization that can be more than 100 meters thick. This style of mineralization is characteristic of the stringer zones that are known to occur beneath VMS systems. The recent surveys through geological mapping and sampling conducted at Rio Negro indicate occurrence of gold mineralization in favorable intrusive host rocks. This epithermal type gold mineralization at Rio Negro is similar to mineralization found in California district thus indicating good chances for bulk mining activities in the region. Hosted by a northwest trending silicified shear zone in silica flooded and quartz veined sericite and chlorite schists, the gold mineralization at Anori is generally contained in the quartz veins and veinlets. This type of mineralization found at Anori is high grade vein-style mineralization of gold with lower grade disseminated mineralization. Located on the highly productive Cauca - Romeral gold belt, Venecia hosts gold and gold-copper targets. The activities of gold exploration carried on at Venecia indicate that the region has a great potential to host viable porphyry style, bulk-mineable targets and high grade structurally controlled vein zones suitable for more selective underground mining. The gold mineralization at Venecia is primarily porphyry related, structurally controlled and epithermal type of gold mineralization.

All these sources of gold mineralization at Colombia indicate Colombia as an ideal place for carrying out gold mining and exploration projects.
