Charter Oak Mine, Blue Wing
District, Beaverhead County, Montana
The Charter Oak exploited two narrow pipe-like replacement bodies localized alongside a north trending fault. The ore occurred in Mississippian Madison limestone which has been thrust over Tertiary andesite. The mine is credited with meager production but has produced a number of secondary minerals including wulfenite, mimetite, pyromorphite, hemimorphite, cerussite, descloizite, and a few others.
