Comments

Comment (Location): SW OF HUMBOLDT SHAFT; SE OF ARIZONA CENTRAL SHAFT. ; INFO FROM LAND.ST :(1973)

Comment (Development): OWNERS INCLUDED DETROIT COPPER MINING CO OF ARIZONA; MANGANESE BLUE ORE BODY AND SHAFT ARE ALSO LOCATED ON COPPER MOUNTAIN CLAIM; COPPER MOUNTAIN MINE TUNNEL EXTENDS ONTO ARIZONA CENTRAL CLAIM

Comment (Deposit): COPPER MOUNTAIN MINE OPENS ONTO ARIZONA CENTRAL VEIN AND ONTO SEVERAL IRREGULAR CARBONATE DEPOSITS IN LIMESTONE.

Comment (Production): PRODUCTION DATA INCLUDED IN DETROIT COPPER CO MINES; OTHER DETROIT COPPER CO MINES ARE THE ARIZONA CENTRAL, MANGANESE BLUE, RYERSON, YANKIE, AND MONTEZUMA MINES.

Comment (Workings): DEVELOPMENTS INCLUDED A 1000 FT TUNNEL THAT RUNS TO THE NW, 500 FT BELOW THE WESTERN CREST OF COPPER MOUNTAIN, IN THE ARIZONA CENTRAL CLAIM. SEVERAL STOPES IN THE COPPER MOUNTAIN AND BLUE MANGANESE LODES, REACHING 100 FT IN WIDTH; EXTENSIVE DRIFTING ALONG VEINS.

Comment (Geology): INTERGROWTHS OF MAGNETITE, PYRITE, ZINC BLENDE, AND CHALCOPYRITE ARE IRREGULARLY DISTRIBUTED IN THE CARBONATES. CHALCOCITE ORE BODY IS USUALLY CONSIDERED TO BE A PART OF THE HUMBOLDT LODE OR AN EXTENSION OF THE WELLINGTON VEIN. ABOVE DESCRIBES THE SECTION OF THE COPPER MOUNTAIN TUNNEL THAT RUNS THROUGH THE NW PART OF THE ARIZONA CENTRAL CLAIM. COPPER MOUNTAIN CLAIM HAS ONLY A FEW CENTRAL VEINS OR SEAMS, UNLIKE THE OTHER GREAT ORE BODIES OF COPPER MOUNTAIN.
