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): THE TONNAGES IN MATRIX 1 INCLUDE OXIDE AND SULFIDE ORE AS A MIXED ORE. THE QUANTITY IN MATRIX 2 WAS CALCULATED BY ASSUMING THAT THE LOW GRADE RESOURCE WOULD BE MINED FOR THE SAME LENGTH OF TIME AS THE HIGH GRADE LEACH MATERIAL OR (10,000MTPD) (10 YRS)(357DAYS/YR)=35,700,000 METRIC TONS. WASTE TONNAGE (LOW GRADE CU) DUMP LEACHED HIGH GRADE LEACH MATERIAL
Comment (Deposit): PROPERTY COULD BE MSHA.DBF # 0201656/PHELPS DODGE CORP. (3/95). AS OF 3/28/77 OXYMIN HAD TERMINATED ITS EXPLORATION PROGRAM IN DUBACHER CANYON. THE RECOVERY GIVEN IN THE YIELD SET IS THE PRODUCT OF 0.88 (SX RECOVERY) X 0.98 (ELECTROWINNING RECOVERY) X 0.46 (LEACHING RECOVERY) = 40% (OVERALL RECOVERY)
