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 = Malachite in fractures, amygdules, and volcanic breccias in amygdaloidal basalt flows of the Triassic Nikolai Greenstone. Tunnel was driven in a northwest- trending fracture zone at the contact between a flow breccia and an overlying amygdaloidal basalt flow.

Comment (Workings): Workings / Exploration = Explored by open cuts and 2 adits, one of which was 87 ft long; reported caved in 1940. Surface and underground workings.

Comment (Reference): Primary Reference = Moffit, 1954, USGS B 989-D, p. 204-205

Comment (Deposit): Other Comments = Nikolai Greenstone hostrock is known for its anomalous Cu content.

Comment (Deposit): Model Name = Massive sulfide

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Late Triassic
