Ingersol Mine, Blue Wing District, Beaverhead County, Montana
The Ingersol, also known as both the Ingersoll and Bob Ingersoll, exploited a replacement ore body in the the same stratigraphic horizon as the nearby Charter Oak mine. The mine was opened by a number of adits and shallow shafts. Like the Charter Oak, the ore occurred in Mississippian Madison limestone which has been thrust over Tertiary andesite. The mine is credited with minor production but has produced a number of secondary minerals including wulfenite, mimetite, pyromorphite, hemimorphite, cerussite, descloizite, and a few others.
