A W-Ag-Pb-Zn-Bi-Sn mine located in sec. 13, T19S, R40E, MDM, about 1.2 km (0.7 mile) SE of Ophir Mountain (coordinates of record) and about 1.5 km (5,100 feet) N of Darwin. Owned by the Darwin Mines, Inc. and then Anaconda Copper Co.

NOTE: This mine does not have a separate USGS MRDS database file assigned. It is mentioned in the files for the mine groups in the Darwin Mines.

NOTE: This is one of several mines incorporated into the "Darwin Mine" of the Anaconda Corp. It was also later incorporated into the group termed the "Darwin Mines," owned by Mexicanus Colorado Inc.

In 1945 The Anaconda Co. purchased the Bernon Defiance, Driver, Essex, Independence, Lane, Lucky Jim, Promontory, Rip Van Winkle and Thompson mines, and other small properties In the Darwin quadrangle and the Columbia mine at the south end of the Darwin Hills in the Coso Peak quadrangle, and they have operated some of them from 1945 to 1955.

The Company „Project Darwin LLC“ acquired the Darwin mines and 58 patented mining claims in 1996. The company is looking for investors to re-start the Darwin mines.

NOTE: Coordinates provided are approximate to the center of sec. 13.
