Application of Spontaneous Potential Profiles in the Exploration of Golf-Rich Epithermal Low Sulfidation Veins in a Humid Region

This paper presents results obtained during exploration of gold-rich quartz veins in low mountain, humid environments of the Colombian Andes, South America. Spontaneous Potential profiling was used to evaluate strike-slip duplex structures and to locate gold-rich veins in distensive zones of a vein system. Six days of total field work helped to model the deposit, and provided ideas on where to continue exploring with trenches. Similar exploration techniques may be applied to greenstone belt-hosted mesothermal shear zones and some epithermal base-metal deposits.
