Rain revisited: New structural and stratigraphic insights and their implications for Carlin-type deposits

$10.00

The Rain mining district, located in southwest Elko County, has produced approximately
1.4 Moz of gold from both open pit and underground mines. Carlin-style
gold mineralization at Rain is interpreted to be late Eocene in age, and is hosted in
breccias localized in the lower MississippianWebb Formation and its contact with the
karsted late Devonian Guilmette Formation. These breccia bodies have traditionally
been interpreted to be the result of structural preparation related to dextral-reverse
motion on the Rain fault and multiple subsequent hydrothermal events.
