MLA 10-91 - Mineral Resource Investigation Of The Trinities Study Area, Elmore County, Idaho

In 1989 and 1990, the Bureau of Mines conducted a mineral resource investigation of the 122,000-acre Trinities study area, located in the Trinity Mountains of south-central Idaho. No identified mineral resources were delineated during this study. There are 58 lode mining claims within the area. Five localities contained elevated metal concentrations which may indicate precious metal mineralization at four localities and molybdenum-precious metal mineralization at another. Four of the five localities appear to form a northwest trend through the center of the study area. Twenty-eight individual sites contain anomalous concentrations of gold, silver, bismuth, molybdenum, and beryllium.
