An Fe-Ag-Talc-Clay-Au-Cu-Ba [baryte] mine located in sec. 31, T10S, R2W, SLM, one mile SSW of Mammoth Peak and 1 mile E of Silver City, on private land. Discovered in the 1945 by the Filtrol Corporation; closed in 1974. Owned by the Anaconda Minerals Co. (Division Of Atlantic Richfield), Dragon Consolidated Mining Co. Iron was mined from 1897 to 1930; halloysite was mined from 1931 to 1974.

Mineralization is a complex metallic-non-metallic deposit hosted in limestone, the Ajax Dolomite and chert. The ore body is podiform with a depth-to-bottom of 91.44 meters. The iron ore is massive compact to spongy botryoidal masses. Local alteration is argillization. Local rocks include Tertiary intrusive rocks in central Utah.

Workings include surface and underground openings with a length of 1,524 meters, an overall depth of 152.4 meters, and an overall width of 60.96 meters, and comprised of an open pit 300 feet deep plus a vertical shaft 1,065 feet deep with drifts and drill holes. The open pit was mined for many years on a small scale. The shaft was mined for a few years in the bottom of the pit. The deepest level is 500 feet with minimal workings. Timber fire and difficult conditions ended the operation.

Product (halloysite) had high value for Catalytic cracking of oil. Gibbsite in ore suggests advanced argillic environment, as does proximity to enargite-quartz lodes.
