Limestone Creek

The Limestone Creek is a silver and nickel 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 (Reference): Primary Reference = Foley and others, 1989

Comment (Deposit): Other Comments = This is the only report of platinum-group metals in the Chandalar quadrangle. The actual presence of platinum-group metals, however, is questionable.

Comment (Geology): Geologic Description = Nickel, palladium, and silver were reported in an X-ray analysis of rock from a thrust sheet of Skajit Limestone (Brosgi and Reiser, 1964). The occurrence is in a section of Skajit Limestone that has overridden Devonian(?) quartz muscovite schist along a major northeast-trending thrust fault. A later examination of the occurrence (Foley and others, 1989) found no evidence of anomalous nickel, palladium, and silver. Heiner and Wolff (1968) described Limestone Creek as a placer gold occurrence on which one claim was located in 1954, but inactive since then. There are no other reports or any evidence to substantiate that this site was a placer gold occurrence.

Comment (Exploration): Status = Inactive
