La Colosa mine Wikipedia

La Colosa is a porphyry gold mine in Colombia. The mine is located in Cajamarca, Tolima on the eastern flanks of the Central Ranges of the Colombian Andes. La Colosa has estimated inferred resources of 24,000,000 ounces (680 t) of gold, grading at 0.9 to 1.0 milligram per kilogram (1.4×10 to 1.6×10 oz/lb) of Au. In 2015, the mine produced 1,810.35 grams (63.858 oz) of gold. In 2016, 88.4% of the mining value in Colombia came from coal and gold combined, with nickel following at 9.3%.
