The Yuma Mine is a copper mine located in La Paz county, Arizona at an elevation of 1,601 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.

Land Status

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

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.

Comment (Deposit): THIS RECORD CONTAINS DATA FROM DUPLICATE RECORD D002945 OF J.W. HASLER WHICH HAS BEEN DELETED FROM MAIN MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
