From 1984 to 1986, studies were conducted to assess the potential for undiscovered mineral resources in wilderness study areas on the Owyhee Plateau. The results of these studies have been published in a series of U.S. Geological Survey Bulletins. Since that time, low-grade, high-tonnage epithermal hot-spring gold-silver deposits have been recognized in the region north of the wilderness study areas. The recognition that this mineral-deposit model is applicable in the region, coupled with new data that has become available to the U.S. Geological Survey, reinterpretation of existing geochemical data, and known-deposit data suggest that similar deposits may be present elsewhere on the Owyhee Plateau. This report is an additional assessment of the Battle Creek, Bruneau River, Deep Creek-Owyhee River, Jarbidge River, Juniper Creek, Little Owyhee River, North Fork Owyhee River, Owyhee River Canyon, South Fork Owyhee River (ID-016-053), Upper Deep Creek, and Yatahoney Creek Wilderness Study Areas in Idaho Wilderness Study Areas in Idaho in light of those new data.
