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 (Reference): Primary Reference = Gamble, 1988
Comment (Geology): Geologic Description = A sample of gossan localized along a fault in marble contained 720 ppm Zn, 600 ppm As, 130 ppm Sb, 130 ppm Cu, and 100 ppm Mo (Gamble, 1988). Bedrock in this area is Paleozic marble and a pelitic schist assemblage of possible Cambrian or Precambrian age (Till and others, 1986).
Comment (Geology): Age = Cretacous or younger Appears to post-date regional mid-Cretaceous metamorphism.
