| Deposit | MARBRIDGE MINES, LTD., JOINTLY OWNED BY FALCONBRIDGE NICKEL MINES, LTD., AND MARCHANT MINING CO., LTD., STARTED MINING NICKEL SULFIDE ORE IN MARCH 1962 FROM A DEPOSIT IN LA MOTTE TOWNSHIP, IN NORTHWESTERN QUEBEC. MINERALIZATION CONSISTS OF PENTLANDITE AND PYRRHOTITE ALONG THE MARGIN OF PERIDOTITE (NORTHERN MINER, DEC. 19, 1963). ON DEC. 31, 1963 ORE RESERVES WERE ESTIMATED AT 143,330 TONS AVERAGING 2.28% NICKEL TO A DEPTH OF 900 FEET; MORE ORE WAS BEING DEVELOPED AT GREATER DEPTH AND IN TWO THEN (1963) NEWLY DISCOVERED ORE SHOOTS (CANADIAN MINES HANDBOOK 1964, P. 190). THE COPPER CONTENT OF THE ORE IS VERY LOW, ABOUT 0.10%. ONE OF THE NEWER ORE SHOOTS, LOCATED 3,000 FEET AWAY FROM THE ORIGINAL MAIN DEPOSIT, WAS BEING INTENSIVELY DRILLED IN 1964; IT APPEARED TO BE OF A HIGHER GRADE AND TO BE WIDER (NORTHERN MINER, JULY 16, 1964) THAN THE DEPOSIT BEING MINED. CORNWALL, H.R., 1966, INDICATES A SULFIDE DEPOSIT OF LESS THAN 10,000 TONS OF CONTAINED NICKEL, HOWEVER THIS ESTIMATE SHOULD BE |
