Report: Arcturus Dry reclaimed pits and trenches mark the site of the Arcturus. Little geology is visible today, but the USGS (1978) describe it in some detail. Apparently ore containing gold, pyrite, arsenopyrite, galena, and chalcopyrite was mined from the N striking, 30-80E dipping contacts of limestone, sandstone, and shale within the Three Forks formation. Some disseminated mineralization also exists in the limestone and sandstone. Exposures of the Cretaceous, gabbroic Black Butte stock lie a few hundred feet away. Seven samples averaged a trace of gold, .1 oz/ton silver, .29% copper, .01% lead, and .57% zinc. The USGS stated that the low metal content does not preclude the existence of resources. Recent exploration drilling has taken place in the area, but results have not been released.
