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 (Location): MORE EXACT MERIDIAN LOCATION NE 1/4 NE 1/4 SE 1/4 SEC. 28, T 21S, R 14E.

Comment (Development): L60, ECONOMIC STUDY (1957) L60 ECONOMIC STUDY (1975 - 76)

Comment (Deposit): SEVERAL ORE BODIES MAKE UP THE DEPOSIT - AVERAGE SIZE OF THE BODIES IS ABOUT 150 X 50 FEET. THE ORE BODIES ARE USUALLY ELONGATE ALONG PALEOCHANNEL DEPOSITS.

Comment (Workings): THE WORKINGS OF THE INCLINE #8 (WEST) MINE AND THE #8 (INCLINE) MINE ARE COMBINED ON THIS DESCRIPTION. EAST HALF OF MINE IS FLOODED.

Comment (Geology): MINERALIZATION IS LARGELY CONFINED TO PALEOCHANNELS AND IS CLOSELY RELATED TO PLANT REMAINS WHICH HAVE BEEN PARTIALLY OR WHOLLY REPLACED BY URANIUM AND/OR VANADIUM MINERALS.
