Mineralized belt of Cauca Field Trip
From 17th to 21th of November of the 2014 the second annual field trip of the SGA-Colombia Student Chapter was made in order to visit three gold deposits located on the Central Cordillera of the Colombian Andes. The Field Trip start with the visit of two major deposits: the “La Colosa” in the Tolima Department and the “Marmato” in the Caldas Department, both located in the called “mineralized belt of Cauca”, at the end, we went to a small but solid Project, in the municipality of Cisneros, in the Antioquia Department.
As we said before, the first deposit was the “La Colosa” proyect, it belong to AngloGold Ashanti and is still under the phase of exploration and prospecting, yet it has an inferred resource of 26,8 million ounces of gold resource, being an excellent porphyry deposit rich in gold and minor amounts of copper and molybdenum. Initially, on the November 18 we were in the city of Ibagüe (Tolima Department) in the logging room of this project, there geologists showed us the main features of the deposit right through presentations, maps and recognition of drilling cores, at end the day we learned some about the geotechnical processes related to mining activity.
