Waucoba Mine

Also known as the Last Rose.

From the California Journal of Mines and Geology, Vol. 47, No. 1, Jan. 1957:

2 unpatented claims are owned by Stuart Bedell, Big Pine, California.

Scheelite is in parallel bands in argillite interbedded with limestone and underlain by quartzite. Ore bodies are small, irregular, and discontinuous, and both the ore and the country rock are highly fractured. THe area is cut by many faults. Granodiorite, not exposed underground, crops out north and west of the mine, and was probably the source of the ore-forming solutions.

Work done at the mine consists of a 168-foot shaft inclined 55 degrees NE. and two main levels 85 and 104 feet below the shaft collar. An intermediate level, which does not connect with the shaft, is about midway between the two levels in the northwest section of the mine. Workings total 700 feet in length. Most of the ore produced was from an area northwest of the shaft on the 80-foot level.

J.L. Danzigner worked the property from 1939 to the fall of 1942. First milling was by dry concentration, later replaced by a mill which included primary crusher, rolls, screen and two Wilfley concentrating tables in series. Water was obtained from Waucoba Springs by means of a three-mile pipeline, financed by a Reconstruction Finance Corporation loan. Production figures are not available, but Danzigner states that heads assays averaged between one and two percent WO3 (tungsten oxide). Concentrates were sold to the Molybdenum Corporation of America.

A massive quartz vein which crops out southeast of the shaft carries copper silicates and carbonates and $2.00 worth of gold per ton. The mine was originally located as a copper prospect.

The property is idle.
