Fluorescent calcite and fluorite can be found here in the mine and on the dumps.
The Rialto mine head frame and surrounding area in 1968. The mine produced some nice little specimens of cerussite, some of which were associated with wulfenite. The crystals were small, not larger than a quarter of an inch. It also produced little fluorite cubes, some covered with micro mimetite and some associated with wulfenite.
