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): BRUCE OREBODY AND OLD DICK OREBODY ARE ALONG SAME STRATIGRAPHIC INTERVAL, WITH BRUCE UNDERLYING OLD DICK. TWO MINES ARE LISTED SEPARATELY DUE TO HISTORY, MINING, AND DEVELOPMENT. GEOLOGICALLY, THE TWO MILES EXPLOITED THE SAME OREBODY. THIS RECORD CONTAINS DATA FROM DUPLICATE RECORD W002662 OF D.P. COX WHICH HAS BEEN DELETED FROM MAIN MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Deposit): Discovery Year: LATE 1950'S

Comment (Reserve-Resource): ASSUMES 90% CU RECOVERY.

Comment (Location): BRUCE SHAFT LOCATED 800 FT SOUTH OF OLD DICK MAIN SHAFT. ; INFO FROM LAND.ST :(1964)

Comment (Development): BRUCE ORE BODY DISCOVERED BY DRILLING FROM UNDERGROUND LEVELS OF OLD DICK MINE AND SURFACE. BRUCE MINE IS SEPARATE FROM OLD DICK MINE ALTHOUGH THEY ARE CONNECTED ON THE 910 FT. LEVEL OF THE OLD DICK MINE.

Comment (Deposit): DEPOSIT IS MASSIVE SULFIDE LENS IN PROTEROZOIC METAVOLCANIC ROCKS. DEPOSIT LOCALIZED AT OR NEAR CONTACT OF RHYOLITE AND ANDESITE.
