This is a small district on the east flank of the Sierra Nevada in northern Mono County a few miles southwest of Coleville. The principal sources of gold have been the Al Mono and Golden Gate mines, which were active in the late 1890s and early 1900s. The deposits consist of quartz stringers containing native gold and sulfides or massive sulfide bodies containing disseminated gold. Some narrow kaolinized gold-bearing seams are found. Country rock consists of schist, slate, greenstone, and quartzite. Copper, lead, zinc, and cadmium also occur here.
