The induced polarization (IP) method was originally developed for field use in porphyry copper exploration and has now advanced to detection of other deposit styles with sulphide content. It is the only geophysical technique capable of directly detecting scattered primary sulfide mineralization. When current flows across the surface of a mineral exhibiting metallic-like conductivity, the behavior is like a metal electrode in an electrolyte. An over-voltage or additional voltage, over that required to pass current through the normal ohmic resistance of the ground, within the electrolyte in the rock pour spaces is required to force the current across the electrolyte-metal particle interface, which behaves as a charged capacitor.
Ground IP is next. Holding all of my WOLV shares tight, and long.
