Deposit Discovery Year: LATE 1950'S
Deposit DEPOSIT IS MASSIVE SULFIDE LENS IN PROTEROZOIC METAVOLCANIC ROCKS. DEPOSIT LOCALIZED AT OR NEAR CONTACT OF RHYOLITE AND ANDESITE.
Deposit SEE OLD DICK MINE (MRDS NO. M003474).
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.
