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 (Reference): Primary Reference = Sainsbury, 1975

Comment (Workings): Workings / Exploration = No workings are known at this location.

Comment (Deposit): Model Name = Sulfide vein in marble

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = Sainsbury (1975, p. 85) describes this occurrence as a 4 inch-wide chalcopyrite vein in a limestone (marble) cliff. This exposure is supposed to be on the north side of the headwaters to Independence Creek and near to a large magnetic anomaly. Till and others (1986) show exposures of Paleozoic marble on both sides of French Creek at this location. This is the only place in the headwaters of Independence Creek that the bedrock geology appears to match Sainsbury's (1975, p. 85) original description.

Comment (Geology): Age = Cretaceous ; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
