The Unnamed Prospect is a tungsten mine located in Cochise county, Arizona at an elevation of 4,751 feet.

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): SCHEELITE IS MORE ABUNDANT THAN HUEBNERITE. EXAMINATION OF NUMEROUS VEINS SHOWS TRACES OF SCHEELITE ARE COMMON EAST OF MERIDIAN OF TRIANGLE T RANCH. SCHEELITE CAN OCCUR OUTSIDE QUARTZ VEINS IN SILICIFIED AND MUSCOVITIZED QUARTZ MONZONITE.

Comment (Deposit): A SECOND VEIN SYSTEM TRENDS S 60 W.

Comment (Deposit): QUARTZ VEINS ARE ABUNDANT IN MARGINAL PARTS OF THE QUARTZ MONZONITE. SOME VEINS ARE SHEARED. ; INFO.SRC : 1 PUB LIT

Comment (Deposit): Discovery Year: PRIOR TO WORLD WAR 1

Comment (Geology): CLIFF-FORMING LIMESTONE AND DOLOMITE. ; GEOL.DESC: TUNGSTEN BEARING QUARTZ VEINS CUT QUARTZ MONZONITE. SOME VEINS OCCUR EN ECHELON. SOME CONCENTRATION OF TUNGSTEN OCCURS NEAR A LIMESTONE INCLUSION 3,300 FT. WSW OF CENTURION MINE. S-SHAPED EN ECHELON FAULTS INDICATE RIGHT LATERAL MOVEMENT ALONG EN FAULTS.
