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.

Comment (Reserve-Resource): ORE BODY DIMENSIONS INDICATE THAT AS MUCH AS 250,000 ST OF ORE COULD STILL BE PRESENT (SAWYER AND OTHERS, 1992).
Comment (Geology): VERY HIGH GRADE ZINC DEPOSIT WITH VOLUMES OF SOLID SPHALERITE.
Comment (Development): OPERATORS INCLUDED JONATHAN GORDON; 14 UNPATENTED CLAIMS
Comment (Location): INFO FROM LAND.ST :(1979)
