Satelite View

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)

Comment (Reserve-Resource): OTHER NAMES:B-HILL;HILL JONES. RESERVES FROM PHELPS DODGE SEC FM-10K REPT. P. 14. GRADE REPORTED AS ACID-SOLUBLE

Comment (Geology): DELAFOSSITE AND MELANOCHALCITE ARE ALSO PRESENT.
