Calvert Hill Mine adds a tungsten-skarn flavor to the Montana list, with Mindat describing a surface mine in Cambrian Meagher Formation limestone and listing scheelite, garnet, beryl var. aquamarine, chalcopyrite, molybdenite, pyrite, and smoky quartz in the district. That mineral spread makes it a stronger educational pick than another agate bar from the same river system.
