Industrial and Fuel Minerals of Manitoba

Introduction The major development of industrial minerals in Manitoba has been in building materials. 'The building-stone industry is developed far beyond the needs of the Province, and the well known Tyndall limestone is marketed over a wide area throughout the other provinces to Canada. Similarly, gypsum and gypsum products are produced in excess of local requirements and are exported to adjacent provinces. The crushed-stone, sand and gravel, limestone, and lime industries are sufficiently developed to supply the needs of the Province and, notably in the case of lime and lime-stone, there is a surplus for export to the adjacent provinces and to the United States. The manufacture of common brick is well established, but for face-brick and other clay products the Province is dependent largely on importations. Production of silica-sand will increase as Canadian markets become available through recognition of the utility value of the Black Island sand as foundry-sand and for other purposes. There is some possibility of the export of feldspar, of lithium ore and concentrates, and perhaps of salt. A considerable part of the Province has not been seriously prospected for industrial minerals and it may be expected that, as time goes on, other deposits of non-metallic minerals will be discovered and opened up, especially as the prairie provinces become more industrialized. At the present time, there is some activity in the southern part of the Province based on gas and oil indications. Whatever may be the outcome of this work, it should yield valuable information concerning the geological structure of the area.
