Comments on the workings information

  • OPEN PIT, SHAFTS, TUNNELS, ADITS, ETC.

Comments on development

  • PLACER PRODUCTION WAS FIRST UNTIL 1867. SILVER MINING STARTED ON A LIMITED SCALE IN 1866. THE ANACONDA CLAIM STARTED THE HIGH GRADE COPPER PRODUCTION IN 1882. MN WAS FIRST PRODUCED IN 1917. ZN STARTED AROUND 1916. IN 1944 THE FIRST MAJOR CHANGE IN MINING METHODS, IT WAS BLOCK CAVING. NATURE OF DISCOVERY ALSO: B ORE MINERAL IN PLACE.

Deposit VEIN SYSTEMS. THE OTHER CLASS OF ORE IS THE SILICEOUS SILVER. THE COPPER CORES CONTAIN A LITTLE SILVER; THE AG ORES RARELY CONTAIN CU; BOTH CU AND AG ORES CONTAIN LITTLE AU, AND THE HIGH-GRADE AG ORE CONTAIN IMPORTANT AMOUNTS OF AU. THE AG-BEARING AREA IS MUCH LARGER THAN THE CU-BEARING AREA, WHICH LAPS AROUND ON THE N AND W. IN THIS LARGE AREA THE BEINS OCCUR IN SIX DIFFERENT CLUSTERS. THE LEXINGTON GROUP STRIKES N75E TO S65E. RAINBOW GROUP WHICH INCLUDE THE VALDEMERE SYSTEM, NE CROSS VEINS AND THE RAINBOW LODE. THE NORTHERN OR WABASH GROUP ARE SHALLOW AND ARE NOT PROFITABLE. THE MISSOULA GULCH GROUP BORDER THE COPPER VEINS. THE WESTERN OR APLITE GROUP, THE VEINS ARE IN APLITE. THE SOUTHERN AND EASTERN GROUPS ALSO HAVE MANGANESE WITH THE AG.
Deposit RECORD W019031 HAS BEEN MERGED AND DELETED.
Deposit QUARTZ-MOLYBDENITE VEINS, "S" VEINS WHICH ARE TRANSITIONAL TO MAIN STAGE VEINS WHICH ARE THE ANACONDA, BLUE, AND STEWARD SYSTEMS. IN THE ANACONDA SYSTEM THE VEINS STRIKE ABOUT N65-80E AND DIP STEEPLY S IN THE OUTER PART OF THE DISTRICT. IN THE CENTRAL PART THEY STRIKE N75-80W AND DIP STEEPLY N TO S. EXCEPT FOR THE EN-ECHELON GAPS, THE MAJOR VEINS OF THIS SYSTEM CONTAINED THE BEST VEIN ORE IN THE DISTRICT. THE BLUE SYSTEM VEINS STRIKE NW AND ARE BEST DEVELOPED IN THE CENTRAL PART OF THE DISTRICT. WITHIN A CORE ZONE AT DEPTH THEY OCCUR TO THE EXCLUSION OF VEINS OF THE ANACONDA SYSTEM. IN THE OUTER PARTS OF THE DISTRICT THE BLUE SYSTEM VEINS ARE RARE AND THE ANACONDA VEINS ARE DOMINANT. THE BLUE SYSTEM VEINS ARE BARREN NEAR THE SURFACE AND IMPROVE WITH DEPTH. IN THE S PART OF THE DISTRICT THEY SURPASS THE ANACONDA SYSTEM ON THE DEEPER LEVELS AS PRODUCERS. THE HANGING WALL STEWARD SYSTEM STRIKES E-W TON75E AND DIPS 30-50S. THESE VEINS IMPROVE WITH DEPTH. THESE WERE THE COPPER
