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): PILLIKIN DEPOSITS OCCUR IN A TABULAR, NNW TRENDING ULTRAMAFIC BODY, 3/4 MI WIDE AND 4 MI LONG, THAT DIPS STEEPLY TO THE EAST. THE GENERAL ORIENTATION OF THE ORE BODIES IS PARALLEL TO THE WESTERN CONTACT OF THE ULTRAMAFIC AND METAMORPHIC ROCKS.
Comment (Deposit): SOME OF THE SILICIFIED AND DEEPLY WEATHERED DUNITE IN SHOVEL PIT NO. 7 IS SLIGHTLY NICKELIFEROUS. ; INFO.SRC : 1 PUB LIT
Comment (Deposit): THERE ARE AT LEAST THREE MAJOR ORE ZONES CONSISTING OF 13 OREBODIES AND MANY SMALLER ONES.
Comment (Workings): WORKINGS CONSIST OF A LARGE PIT OF DIMENSIONS 200 FT X 50 FT X 50 FT; 9 SMALLER PITS, NUMEROUS BULLDOZER CUTS AND TRENCHES.
