The Black Dike Mine is a uranium mine located in Pima county, Arizona.
About the MRDS Data:
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 (Commodity): SHAFT ORIGINALLY SUNK PROBABLY FOR COPPER IN WWI THEN FOR URANIUM IN 1950'S.
Comment (Production): PROBABLE PRODUCTION DURING WWI FOR PB, AG, CU
Comment (Deposit): MINERALIZATION ON WALLS OF DIKE - DIMENSIONS GIVEN ABOVE. MINERALIZATION OCCURS AT CONTACT OF GRANITIC GNEISS AND BASALT DIKE WHERE THE ZONE IS ALTERED TO GARNET, CHLORITE, AND EPIDOTE.
Comment (Workings): MORE WORK HAS BEEN DONE SINCE BULL. 1147 REPORT.
Comment (Geology): OUTCROP OF SILICIFIED SCHIST WITH THIN COATING OF MN OXIDE. GIVES APPEARANCE OF LARGE DEPOSIT. ; GEOL.DESC: AGE UNKNOWN - PROBABLY TERT- CRET.
Comment (Deposit): THIS RECORD INCLUDES INFORMATION FROM DUPLICATE RECORD M000150 WHICH HAS BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Deposit): Discovery Year: WORLD WAR I; AGAIN 1950'S.
Comment (Reserve-Resource): LOCAL CONCENTRATIONS OF URANIUM MINERALS COULD BE FOUND BUT LIKELYHOOD OF LARGE HIGH-GRADE DEPOSITS IS WEAK.
