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.

Comments

Comment (Economic Factors): A 500 S.T./D CARBON-IN-PULP PLANT CONSTRUCTED BETWEEN 1979 & 1982, AS WELL AS ELECTROWINNNG FACILITY.

Comment (Production): 1077 G AU RECOVERED IN 1892 IN PLACER OP. P. SHIFTED FM PLACER TO LODE 1898. NO REPORTED PROD. 1904-1943. DRILL CORE INFO. AVAILABLE IN FILE REPORT. NORANDA DOES NOT PLAN TO MINE THE SULFIDE ORE IN THE NEAR FUTURE.

Comment (Production): HP-REC 005 AU, AG, CU RECOVERED FM 131000 MT CRUDE ORE. HP-REC 006 AU, AS, CU RECOVERED FM 205000 MT CRUDE ORE. HP-REC 007 AU, AG, CU RECOVERED FM 38000 MT CRUDE ORE. EXPLORATION SUBSEQUENT TO 1979 HAS RESULTED IN DELINEATION OF ADDITIONAL GOLD RESERVES. TONNAGE AND GRADE OF ADDITIONAL RESERVES UNAVAILABLE.

Comment (Economic Factors): SURFACE MINE CURRENTLY IN PRODUCTION. NO DATA RELATIVE TO TO PIT ARE PRESENTY AVAILABLE. PRODUCTION IS FROM GOLD (OXIDE) ZONE. MINING RATE GREATER THAN 454 T/D.

Comment (Economic Factors): RECORD 103 LINE 2 THE DISTANCE IS 3.5 X 100. THUS THE ACTUAL COST IS 0.00003/KM/MT.

Comment (Reserve-Resource): IN ORDER TO RECOVER ALL THE ORE., THE STRIPPING RATIO WOULD GO AS HIGH AS 12:1. 90 PCT PROB. BASED ON ORAL COMMUNICATION W/ NORANDA CO.GEOL. 75 AND 50 PCT PROB.BASED ON FAVORABLE GEOLOGICAL COND.. 90 PCT PROB.BASED ON ORAL COMM. W/ NORANDA CO. GEOL. JUN1978 75 AND 50 PCT PROB BASED ON FAVORABLE GEOLOGICAL COND.

Comment (Environmental Factors): THE NORANDA GREY EAGLE MINE IS A RECENT GOLD AND SILVER MINE (1981) IN THE SAME GENERAL LOCATION AS THE OLDER GREY EAGLE MINE WHICH PRODUCED COPPER. THE WASTE MANAGEMENT FACILITIES AT THE NEW MINE WERE BUILT IN COMPLIANCE WITH EXISTING CODES. NEVERTHELESS, CYANIDE-CONTAMINATED EFFLUENT LEAKED FROM THE TAILINGS DAM, AND THE ANTICIPATED ATTENUATION OF FREE CYANIDE BY METALS IN THE FILL MATERIAL OF THE DAM DID NOT OCCUR. NORANDA INSTALLED A COLLECTION SYSTEM AND AN ADDITIONAL TREATMENT PLANT TO TREAT SEEPAGE FROM THE TAILINGS DAM. THE MINE IS NOW CLOSED, BUT THE TREATMENT PLANT WILL BE OPERATED UNTIL CYANIDE IS BELOW DETECTION LEVELS IN THE SEEPAGE, ESTIMATED AT ABOUT 20 YEARS. THE COST OF THESE MITIGATION EFFORTS HAS RESULTED IN NORANDA SUFFERING A SUBSTANTIAL LOSS ON THIS PROJECT.
