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 (Exploration): Status = Inactive
Comment (Commodity): Ore Material = Sulfide minerals
Comment (Geology): Geologic Description = The country rocks in the general area of the Spud prospect (Koch, 1996, 1997) are Mesozoic or Paleozoic pelitic schist and paragneiss, and subordinate amphibolite and marble. The Spud deposit has been described as a sulfide replacement in marble (Elliott and Koch, 1981, loc. 1). No other geological information about this prospect has been made public.
Comment (Workings): Workings / Exploration = Some diamond drilling and probably some minor trenching.
Comment (Reference): Primary Reference = Elliott and Koch, 1981
