Deposit LARGE SCALE MINING IN THE VALLEY STARTED IN 1962 WITH BETHLEHEM COPPER AND CONTINUED SUCCESSIVELY WITH THE OPENING OF LORNEX IN 1972 AND VALLEY COPPER IN 1986. AMALGAMATION OF LORNEX AND VALLEY COPPER IN 1986 AND THE SUBSEQUENT INCLUSION OF THE HIGHMONT MILL AND PROPERTY IN THE NEW COMPANY, HIGHLAND VALLEY COPPER, BROUGHT ALL THESE PROPERTIES INTO ONE SINGLE MINING AND MILLING COMPLEX. FIGURES IN THIS RECORD REFLECT THOSE OF THE VALLEY COPPER DEPOSIT. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Deposit Discovery Year: 1967-1970
Deposit VEINS & STRINGERS UP TO 3 M WIDE
