For mineral collectors, the Elmwood, Gordonsville, and Cumberland mines in middle Tennessee are well-known for producing fine specimens of calcite, fluorite, barite, galena, and sphalerite.  Some have argued that the finest calcite crystals on Earth have come from these mines.  Specimens in these mines are located in "bugholes" (cavities ranging from an inch or two up to the size of a house or larger) with the mineralization typical of a classic Mississippi Valley type deposit.  The mining district has been in operation since the 1970s and is currently mining zinc ore on a limited basis.
