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 (Deposit): LOCATIONS DOUBTLESS INCORRECT. REPORTED OCCURRENCES. MAY DEPOSIT IN SEC4 AT LEAST BE LEHMANN DEPOSIT WHICH GILLER SAYS MINED BUT DID NOT SHIP ORE IN 1918. IT IS MORE LIKELY THE HORSE MTN DEPOSIT INCORRECTLY PLOTTED AS CR WAS SHIPPED FROM THIS IN 1918.
