Gold Mineralisation in Colombia,
South America

A Brief Introduction

Colombia purports, by far, the longest and most productive history of gold exploitation in South America (Table 1, below), dating from both the pre-Colombian period, and Spanish colonial to recent times. This fact can be primarily attributed to two observations. Firstly, the region geographically occupied by Colombia is geologically underlain by a wide diversity of rock-types and formations which, due to their mode of formation, and the highly active tectonic environment in which they formed, have given rise to a great wealth of mineral abundance (not only in gold, but potentially in silver, copper, zinc, mercury, antimony, platinum and many other metals). Secondly, due to the active process of "mountain-building", the Andean region of Colombia has undergone extensive uplifting and erosion of the various rock formations; an essential process which allows the mineral deposits formed at depth within the earth to be exposed at the earth’s surface, and hence to be "discovered".

(as seen in the Paramo de Frontino, or the historic Buriticá and Marmato-Echandía camps), to intermediate level "porphyry or intrusive" associated gold +/-copper-molybdenite-zinc occurrences which form interesting "bulk-mineable" deposits (Providencia or Murindo, Antioquia), to peripheral, structurally controlled, mesothermal high-grade "gold-only" vein deposits where grades averaging well over one ounce of gold per ton are common (the classic producing camps of Segovia-Remedios and La Bramadora are fine examples).
