An old-time classic chalcoalumite specimen from the type locality - the Copper Queen Mine at Bisbee. Powder-blue chalcoalumite botryoids richly invest all sides of the vuggy gossan matrix. Chalcoalumite is a rare copper, aluminum sulfate. This is undoubtedly old material, dating from the late 1800s-early 1900s, but no proof. Ex. Dennis Mullane Collection.
