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 (Reserve-Resource): DEPOSIT REPORTED ESSENTIALLY MINED OUT AND VERY LIMITED RESOURCES REMAIN ALONG EDGES OF MINERALIZATION.

Comment (Production): MOST PRODUCTIVE U-V MINE IN AZ.

Comment (Deposit): ORE PODS ARE LENTICULAR. HIGHEST CONCENTRATIONS ARE WITHIN 5 FT OF BASE OF CHANNEL. LOWER GRADES TO 20 FT ABOVE BASE. CHANNEL IS 2 MI LONG, 3 MI WIDE, 50 FT DEEP. DIMENSIONS GIVEN ARE FOR MINERALIZED AREA. MINERALIZATION EXTENDS 7 FT INTO THE DECHELLY SANDSTONE.

Comment (Workings): WORKINGS INCLUDE OPEN PIT, INCLINED SHAFTS, AND ADITS. CONCENTRATOR OPERATED TO UPGRADE LOW GRADE MINERALIZATION.

Comment (Deposit): THIS REPORT REPRESENTS A MERGER OF ORIGINAL RECORD M002989 WITH RECORD M030423 OF JAN WILT IN MOLYBDENUM FILE; CONTACT PERSON T.G. THEODORE, USGS.
