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 (Deposit): VEINS, DISSEMINATIONS; INTERSECTION OF TWO FAULTS; ORE GRADE DECREASES AWAY FROM THE INTERSECTION

Comment (Production): PRODUCTION WAS FROM 1948 TO 1952, AND INCLUDED 3 OZ/TON AG WITH MINOR CU AND AU.

Comment (Development): THE LEAD-ZINC OREBODY ON COPPER CANYON MINE GROUND WAS FIRST DISCOVERED IN 1941 BY DIAMOND-DRILLING, AFTER WHICH THE JULIE SHAFT WAS SUNK TO THE 700-FT. LEVEL TO MINE IT. FIRES AND MARKET FLUCTUATIONS CAUSED PRODUCTION TO BE SPORADIC UNTIL 1957, WHEN THE MILL WAS SHUT DOWN, WITH LESSEE ACTIVITY CONTINUING UNTIL 1959 WHEN THE U.S. GOV'T. TOOK IT OVER.

Comment (Workings): SHAFT & CONNECTING WORKINGS

Comment (Geology): ORE GRADE DECREASED NORTHWARD AWAY FROM INTERSECTION OF GULCH AND WEST FAULTS

Comment (Location): 500 FT SE OF VIRGIN SHAFT OF COPPER CANYON MINE

Comment (Deposit): THE LEAD-ZINC OREBODY ON COPPER CANYON MINE GROUND WAS FIRST DISCOVERED BY DIAMOND-DRILLING IN 1941. IN 1947, COPPER CANYON MINING CO SANK THE EXISTING JULIE SHAFT TO THE 700-FOOT LEVEL TO MINE THE LEAD-ZINC OREBODY. PRODUCTION OF PB-ZN ORE BEGAN IN 1948. FIRES AND MARKET FLUCTUATIONS RESULTED IN INTERMITTENT PRODUCTION UNTIL 1957 WHEN THE MILL WAS SHUT DOWN; WITH LESSEE ACTIVITY CONTINUING UNTIL 1959 WHEN THE U.S. GOV'T TOOK IT OVER JULIE SHAFT WAS FIRST PUT DOWN IN 1941 TO MINE COPPER-GOLD ORE. ; INFO.SRC : 1 PUB LIT
