The Magdalen Islands

CIM Bulletin1941
THE Magdalen islands have recently been attracting attention as a possible source of manganese. As early as 1880 small masses of manganese oxides were known to occur in the soil and at least one attempt was made to develop them. In 1939, after the outbreak of war, interest in the possibilities of the field was again aroused and during the winter of 1939-40 claims were taken up by two groups of Toronto interests. The islands also contain large quantities of gypsum.
