MOBIL METAL IONIZATION: AN EFFECTIVE GOLD EXPLORATION TOOL IN NORTHERN NEVADA


FORBUSH, Tyson J., Department of Geology, Brigham Young University - Idaho, 150 Romney, Rexburg, ID 83460-0510 and SMITH, Andrew R., Marigold Mine, Goldcorp, Inc, Valmy, NV 89438, sageextreme@gmail.com

Mobil Metal Ionization (MMI) is a controversial geochemical method used to locate precious and industrial metal deposits. The purpose of this on-going study is to determine the effectiveness of MMI as an exploration tool at GoldCorp's Marigold mine in northern Nevada. This survey evaluated nearly twelve square miles of mine property. Sample analysis aided in the recognition of ore bodies and resulted in the identification of previously unknown faults and shear zones. This study has identified fifteen new drill targets in both previously explored and unexplored areas testing anomalies with reverse circulation drilling. Well logs from all tested drill targets show thick units of minable-grade ore with Au concentrations up to two ounces per ton. It is our conclusion that MMI is both a viable and cost effective exploration tool for the mining industry.
