Since the discovery by conventional prospecting of the Horne deposit in 192(), the Noranda area has produced 82 million tons of copper-zinc-goldsilver ore from sixteen massive sulphide bodies. Recent exploration in the area has consisted of systematic studies employing geology, geophysics and geochemistry. Due to the depth of the deposits being sought, surface geophysical surveys are limited in their effectiveness as DIRECT indicators. However, because of the geological environment, surface geophysical methods, and the Induced Polarization method in particular, can be successfully employed as INDIRECT indicators of ore de pos its. Examples of survey results from various properties in the Noranda area illustrate the advantages and limitations of the lnduced Polarization method as an exploration tool in this area.
