Deposit: Almost all of the fluorspar is in a fault zone from 2 to 18 feet in width and over 1800 feet in strike length. Fluorspar generally occurs in a well-defined vein with a definite footwall and a less definite hanging wall in which irregular, random or branching, thinner veins and veinlets are found. Only rarely does fluorspar occur beneath the footwall contact. The mineralized zone ranges from a few inches to 9 feet or more in thickness, and the main vein within this zone commonly is a few inches to several feet thick with abrupt pinching and swelling. In places, especially in hanging wall, the veins and the adjacent altered rock are brecciated. Locally the fluorspar is granulated to a loose sandy material. Some of the ore is stained by iron oxides or, less commonly, by manganese oxides. The fluorite is white to very light gray to very pale green, and consists mostly of medium-grained crystals.

Development: Mine operated by baxter from 1928 to 1951. From 1952 to 1957 mine operated by kaiser aluminum and chemical corp. Mine has been idle since 1957, but the principal claims were relocated in 1970 by howard turley, the present owner.

Geology: The country rock is an olive-gray to medium-gray andesitic volcanic rock which is slightly altered to calcite, sericite, and chlorite. In the fault zone the country rock is argillized, silicified, and somewhat iron stained; it no W consists of quartz, montmorillonite, and a minor amount of sericite.
