The Unnamed (north of Mine Harbor) is a zinc and copper 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 (Geology): Geologic Description = MacKevett and Holloway (1977) reported altered zones at this occurrence, probably related to Tertiary granitic rocks. No exposures of granite rocks were found in the area during U.S. Geological Survey studies in the mid-1980's (Wilson and others, 1988). Instead, these studies indicated extensive silicification and calcification of siltstone and sandstone of the Cretaceous Staniukovich Formation. A rock sample of olive-green siltstone was reported to be anomalous in copper and zinc (Wilson and others, 1987).
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Cretaceous or younger.
Comment (Reference): Primary Reference = Wilson and others, 1988
Comment (Workings): Workings / Exploration = The U.S. Geological Survey mapped and sampled this occurrence in the mid-1980's. Sample 85AJm 765 was reported to be anomalous in copper and zinc (Wilson and others, 1987).
