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.

Comment (Deposit): "probably close to the Koch manganese and feldspar claims in T32N, R79W, 11 mi. south of Casper. A seam of black material wihch carries gold and silver cuts granite. Gold ans siver values have been found in a dolerite dike in the granite." (Bull. 50, p. 92). But Bull. 50 does not list this deposit in the section on silver, therefore silver is not listed in this record as a primary commodity.
