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): USBM GIVES LOCATION AS T6N, R14W, SEC 30 AND LATITUDE 33-50-26N, LONGITUDE 113-44-55W ON SALOME QUADRANGLE.
Comment (Deposit): Discovery Year: 1860'S
Comment (Geology): THE REPLACEMENT OF THE LIMESTONE BY MAGNETITE MAY BE ONE OF THE RESULTS OF THE METAMORPHIC ACTION PRODUCED BY THE INTRUSION OF THE GRANITE IN THIS GENERAL VICINITY.
Comment (Production): PROSPECTED AND MINED INTERMITTENTLY BUT MAINLY FROM 1942 THROUGH 1963.
Comment (Development): PAST OPERATORS INCLUDE: IRONWOOD AND ARIZONA DEV. CO., YUMA COPPER CO., SPRY, LIBERATOR MINES CORP. OF AMERICA, SOUTH CALIFORNIA CHEMICAL CO.
Comment (Deposit): STRONG IRON GOSSANS FROM PRIMARY MAGNETITE AND PYRITE, WITH QUARTZ STRINGERS, CALCITE, AND CONTACT METAMORPHIC MINERALS. WALL ROCKS FRACTURED AND STRONGLY CHLORITIZED AND EPIDOTIZED. HOST ROCK CUT BY NUMEROUS MAFIC DIKES. THE PARTIAL REPLACEMENT OF A LEDGE OF YELLOW CRYSTALLINE LIMESTONE BY MAGNETITE IN THE VICINITY OF THE CAMP IS THE MOST CONSPICUOUS PART OF THE SECTION EXPOSED ON THE PROPERTY.
Comment (Workings): AN ADIT 680 FT LONG CONNECTING WITH A 75 FT SHAFT; TWO WINZES OF 405 AND 420 FT RESPECTIVELY; SHALLOW SURFACE CUTS.
