The Bailey is a gold and silver mine located in Alaska.
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 (Geology): Age = Late Cretaceous or younger; shear zone cuts Late Cretaceous to Tertiary tonalite.
Comment (Workings): Workings / Exploration = Old adit, said to have been 40 ft long, was covered by rock slide prior to 1963. Assays indicated 0.6 oz/ton Au, 1.81 oz/ton Ag, 4.58 percent Cu, and 2.06 percent Mo (Maloney, 1966).
Comment (Geology): Geologic Description = Shear zone in tonalite of Late Cretaceous to Tertiary age. Maloney (1966) reported the shear zone to be 200 ft wide and could be traced for 1,500 ft. The shear zone contains bornite, chalcopyrite, covellite, molybdenite, and pyrite; and strikes east, dipping 75 to 80 N. Mineralization is exposed over an area of 50 ft by 500 ft and over a vertical distance of 300 ft. Assays indicated 0.6 oz/ton Au, 1.81 oz/ton Ag, 4.58 percent Cu, and 2.06 percent Mo (Maloney, 1966).
Comment (Reference): Primary Reference = Maloney, 1966
