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.

Comment (Deposit): MINERALIZATION OCCURS IN WELL-DEVELOPED FRACTURE SYSTEM IN HARDING QUARTZITE NEAR CONTACT WITH FREMONT DOLOMITE AND AT THEIR FAULT CONTAC. SOME MINOR DISSEMINATION OF ORE OUT FROM JOINTS. ORE THICKNESS AND GRADE DECREASE SOUTHWARD; JOINTS PERSIST BUT BECAME TOO NARROW OR TIGHT FOR ADEQUATE CIRCULATION OF MINERALIZING SOLUTIONS. SOME ORE FOUND IN SECOND DRIFT IN HARDING QUARTZITE IN (CHESTER) FAULT CONTACT WITH MANITOU DOLOMITE
