General comments

Subject category Comment text
Deposit SYNVOLCANIC, MAGMATIC ORIGIN OF NICKEL MINERALIZATION INDICATED BY INCREASE IN INTERCUMULATE SULFIDE CONTENT AND PRESENCE OF SEMI-MASSIVE "QUENCHED" SULFIDES IN BASAL ZONE OF PERIDOTITE FLOWS. DUNDONALD DEPOSIT ONE OF SEVEN SMALL NICKEL DEPOSITS THAT OCCUR WITHIN 50 KM RADIUS OF TIMMINS, ONTARIO.
