The Michley is a gold 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 (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = By 1931, a 200-foot crosscut was driven S. 75 E. into the hill through flat-lying quartz-mica schist (Hill, 1933, p. 149). Several narrow quartz veinlets with north-south strikes and steep dips either to the east or west are exposed in the tunnel. The quartz is milky white and does not appear to carry many sulfides. About 155 feet from the mouth of the tunnel, short drifts to both the north and south follow a vein that is oriented N. 4 W., dipping 60 E. near the the crosscut, but is nearly vertical in the face of the south drift. The vein is generally composed of white quartz about 2 inches thick; but in one zone, the white quartz is 12 inches thick with 4 to 6 inches of gouge surrounding it. The ore from a small stope just north of the crosscut is said to have returned approximately $10 of gold per ton (0.48 ounce of gold per ton) (Hill, 1933, p. 149).
Comment (Reference): Primary Reference = Hill, 1933
Comment (Production): Production Notes = Ore from a small stope is said to have returned approximately $10 of gold per ton (0.48 ounce of gold per ton) (Hill, 1933, p. 149).
Comment (Workings): Workings / Exploration = By 1931, a 200-foot crosscut was driven S. 75 E. into the hill (Hill, 1933, p. 149). About 155 feet from the mouth of the tunnel, short drifts to both the north and south follow a vein that is oriented N. 4 W., dipping 60 E. near the the crosscut, but is nearly vertical at the face of the south drift.
Comment (Exploration): Status = Inactive
