Ore controlPRIMARY AND SECONDARY CONCENTRATION. CONCENTRATION AT BASE OF SERPENTINE LAYER, IN FOORWALL PHYLLITES, SHEARS AND BRECCIAS ALONG FOOTWALL. DENSELY DISSEMINATED ORES IN APODUNITIZED SERPENTINES OF THE BOTTOM OF THE INTRUSION AND BRECCIATED ORES AT CONTACTS ARE RICHEST. PHYLLITES SURROUNDING INTRUSION CONTAIN SOME POOR DISSEMINATED ORES. PD CONCENTRATION GREATEST IN PENTLANDITE, PT AND RH IN PYRRHOTITE. CHALCOPYRITE DEPLETED IN THESE ELEMENTS RELATIVE TO OTHER DEPOSITS.
