This is a silver-gold mining area located North of the Tiger District. It covers a few square miles North of Crown King and East of Towers Mountain (diorite mass) at 6,000 to 7,500 feet of altitude.
Country rock is a Northeastwardly-trending belt of schist which is intruded on the East by granite, on the West by granite and diorite, and on the SW by granodiorite. These rocks are cut by Northeastward-trending dikes of granite and rhyolite-porphyry.
Vein gangue consists mainly of quartz with some ankerite and calcite. Most mines are situated in granodiorite (quartz diorite according to Jaggar and Palache), which forms a rounded mass 3 to 4 miles diameter, intruded into Bradshaw granite and still earlier Yavapai schist. The granodiorite is cut by a series of dikes which trend north-northeast across the center of the area. There are three prominent vein systems, which trend north-northeast and generally dip about 60º WSW. The shoot have a tendency to pitch northward. Few of the veins are more than 5 feet wide.
