Geologic map of the Vulture Mine Area, Vulture Mountains, west-central Arizona

The Vulture Mountains, located directly southwest of Wickenburg in central Arizona, contain one of Arizona's premier historic gold deposits, the Vulture Mine. This mine yielded about 340,000 ounces of gold and 260,000 ounces of silver, with average grades of 0.35 oz/ton gold and 0.27 oz/ton silver. In spite of this significant production, the mine has received relatively little geologic study until recently (White, 1988). In order to better characterize the geologic setting of this historically important gold deposit, we mapped the geology of approximately 10 square kilometers centered on the mine. This mapping was partially supported by the U.S. Geological Survey and Arizona Geological Survey Cooperative Geologic Mapping (COGEOMAP) Program. ( 5 pages and one included map plate)
