The Confidence (Eagle Valley district, Nevada) mining area lies in the southern White Rock Mountains of northwesternmost Iron County, about 61 mi northwest of Cedar City. No production has been recorded in the Confidence district (Tingley and Castor, 1991); however, the district has been prospected for Au-Ag. The Utah portion of the Confidence district was drilled on three separate occasions in the 1980s and 1990s.
The Confidence district lies on the Blue Ribbon lineament in the Basin and Range Province. The area is underlain by a series of Oligocene-Miocene volcanic rocks. The main mineralized feature is the west-northwest-trending Confidence Au-Ag vein with the largest development at the Confidence mine, some 600 ft into Lincoln County, Nevada. The old Bergin Au-Ag mine lies on the southeastern projection of the Confidence vein in Utah (USGS Model 25c). Mineralization at the Bergin mine is associated with an 80° southwest dipping quartz-calcite vein cutting Miocene-age rhyolite.
