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 (Geology): Age = Probably Cretaceous or younger, based on the age of the surrounding diorite (MacKevett and others, 1974).
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = The site of an isolated sample of chalcopyrite-bearing quartz float with malachite that contained 49 ppm gold, 74 ppm silver, and 1% copper. (Still and others, 1984). It occurs within a Cretaceous diorite (MacKevett and others, 1974) but may be associated with a small pendant within the diorite, like SK053 or SK052.
Comment (Reference): Primary Reference = Still and others, 1984
Comment (Deposit): Model Name = There is too little information to assign a model type.
