About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Development): 2 SHORT CROSSCUT TUNNELS AND A FEW PITS.TUNNELS AND PITS. EXPLORATION IN 1971-72.
Comment (Deposit): THE WHOLE IS IMPREGNATED WITH GRAINS OF ZINC BLENDE, PYRITE, PYRRHOTITE, AND CHALCOPYRITE. IN PART THE SULFIDES ARE AGGREGATED AS FLAKES AND THIN FILMS IN MINUTE FRACTURES THAT TRAVERSE THE ROCK IN VARIOUS DIRECTIONS. LOCALLY THEY ARE CONCENTRATED IN BANDS AS MUCH AS 1/4 IN. IN WIDTH. SOME BANDS ARE FORMED ALMOST EXCLUSIVELY OF ZINC BLENDE. OTHERS CONTAIN CHIEFLY THE IRON SULFIDES AND CHALCOPYRITE.
Comment (Workings): 75 FT CROSSCUT TUNNEL, A 20 FT CROSSCUT TUNNEL, AND A FEW PITS.
Comment (Geology): DIKE COULD BE MORE THAN A MILE IN LENGTH. 400 FT TO THE EAST OF THE DIKE SOME SMALL PITS EXPOSE A SIMILAR ROCK THAT APPEARS TO BE A PARALLEL DIKE SEPARATED FROM THE MAIN DIKE BY ARGILLITE
