摘要

The Ridenour mine is in the northern part of the Hualapai Indian Reservation in Section 6, Township 31 North, Range 8 West, about two miles southeast of the Colorado River. The mine is near the middle of the top sandy member of the Supai formation which is Permian in age. Total thickness of the Supai formation in this area is about nine hundred feet. The ore minerals occur in veins and brecciated zones which form a semicircular pattern in plan view. Carnotite mineralization forms an enclosing envelope around copper-bearing veins which contain major amounts of malachite, azurite, and chalcocite and minor amounts of chrysocolla, bornite, and chalcopyrite. Gangue minerals are chiefly pyrite and limonite.
