The Mitchell and Myers is a lead and 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 (Workings): Workings / Exploration = Explored by a limited number of open cuts. Samples from the dike contain as much as 0.34 oz/ton Au (Johnson, 1914).
Comment (Deposit): Model Name = Chugach-type low-sulfide Au-quartz veins (Bliss, 1992; model 36a.1 ?) or Epithermal Au vein ?
Comment (Production): Production Notes = No known production.
Comment (Reference): Primary Reference = Johnson, 1914
Comment (Geology): Geologic Description = Johnson (1914) reported a shattered felsic dike, 60 to 67 inches wide, is cemented by quartz stringers up to 8 inches wide that carry gold, arsenopyrite, galena, and pyrite. The felsic dike is Tertiary in age, and strikes N 50 E, and dips 53-75 W. A nearby 3 ft wide quartz vein strikes N 51 W with a 60 E dip, and contains gold, arsenopyrite, galena, and pyrite in a quartz-calcite gangue. Samples from the dike contain as much as 0.34 oz/ton Au (Johnson, 1914). The felsic dike cuts metasedimentary rocks of the Valdez Group.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary or younger; vein cuts a shattered Tertiary felsic dike.
