| Deposit | LOCATION- TAILINGS FROM THE MC GILL COPPER MILL LIE IN PART OR WHOLE OF THE FOLLOWING SECTIONS OF T18N, R64E: 17,18, 21, 28-32. GENERAL LOCATION IS ABOUT 19 KM NE OF ELY. MINING METHOD IS SURFACE. THE TAILINGS DEPOSIT AT MCGILL REPRESENTS A 70-YEAR ACCUMULATION OF TAILINGS FROM THE ADJACENT CONCENTRATOR. OVER THE YEARS THE "NATURAL CLASSIFICATION OF THE COARSE AND HEAVY PARTICLES RESULTED IN A DEPOSIT OF MINABLE GRADE COPPER-BEARING MATERIAL SUITABLE FOR CONCENTRATING AND SMELTING"(NV DIR. BIB. REF. #473). IN 1978-79, KENNECOTT CONDUCTED EXPLORATION AND FEASIBILITY STUDIES ON THE DEPOSIT. IN THE FALL OF 1979, KENNECOTT ANNOUNCED THAT RECOVERY OF COPPER FROM ABOUT 800 HA (2000 ACRES) AWAITED ONLY A CORPORATE GO-AHEAD. IT WAS STATED THAT AN INVESTMENT OF $15 MILLION WOULD BE REQUIRED AND WOULD "PAY FOR ITSELF IN LESS THAN A YEAR"(NV DIR. BIB. REF. #160). THE PLAN WAS TO USE CONVEYORS TO TRANSPORT 9.5 MILLION MT ANNUALLY BACK TO THE MILL AND SMELTER FACILITIES FOR REPROCESSING. RECYCLING OF THE 0.5% CU TAILINGS WOULD TAKE BETWEEN 8 AND 10 YEARS(NV DIR. BIB. REF. #160). TYPE OF ORE BODY - MILL WASTE TAILINGS. IDENTIFIED RESOURCES; MEDIUM. |
