A former Pb-Ag mine group located on the western side of the Darwin Hills.

While there were many mines and prospects within the Darwin District, most of the district's production has come from the larger and more important workings on the west side of the Darwin Hills which were ultimately consolidated and operated by the Anaconda Company as the Darwin Mine. These included the Bernon, Defiance, Essex, Independence, Intermediate, Rip Van Winkle and Thompson workings.

NOTE: Some of these same mines were later incorporated into another group termed the Darwin Mines. See MRDS locality file at: http://www.mindat.org/loc-78712.html.
