The Nikolai Butte is a silver, copper, zinc, and lead 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.

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 = Type of workings: surface. Grab samples assayed >20,000 ppm Cu, and as much as 10 ppm Ag, 15,000 ppm Pb, and 10,000 ppm Zn (MacKevett, 1976).
Comment (Reference): Primary Reference = MacKevett and Smith, 1968
Comment (Deposit): Other Comments = Probably a Kennicott-type deposit but of interest because of high lead and zinc values.
Comment (Geology): Geologic Description = Small prospects on narrow veins in steep faults cutting Triassic Nikolai Greenstone and Triassic Chitistone Limestone and on copper-stained zones along the Greenstone/Limestone contact.
Comment (Deposit): Model Name = Basaltic Cu ?
Comment (Commodity): Ore Material = Unspecified secondary copper
Comment (Commodity): Ore Material = base metal minerals
Comment (Exploration): Status = Inactive
