A Pb-Ag-Au mining area located on the western slope of the Black Hills, from Cherry Creek to Dewey and Northward by the south margin of Mingus Mountain to points a few miles North of Yaeger Canyon on the Jerome-Prescott Road.

The entire southeastern part of the district is occupied by normal Bradshaw Granite. The western foothills are occupied by a persistent belt of fissile chloritic and sericitic schists trending Northward from Texas Gulch East of Dewey to Grapevine Gulch, and Northward. Adjoining this schist is a parallel belt in which the 'greenstone complex' of altered amphibolitic rocks predominates, with smaller inclusions of slate and jasper.
