GOLD-BEARING PRE-COLUMBIAN CERAMIC FRAGMENTS FROM THE MIDDLE CAUCA REGION, COLOMBIA
The Middle Cauca Region is a north-south zone that takes its name from the Rio Cauca and extends from Ibague, Dept. Tolima, in the south, through Dept. Caldas, northward towards Medellin, Dept. Antioquia, Colombia. This region is being explored for porphyry gold and gold-copper deposits and hosts La Colosa, a recent discovery that is estimated to contain 12.3 Moz of gold. Marmato, also in the Middle Cauca, produced alluvial gold before the arrival of the Europeans and now produces gold-silver from pyrite veins in a Miocene stock that may contain 6.6 Moz of gold.
To the best of our knowledge, this is the first attempt to define and link the metal content of ancient Colombian ceramics to the mineral occurrences in the region.
