The growth of the mining industry in British Columbia in the last ten years has been largely the result of the development of large low-grade copper and molybdenum deposits. There are two problems which must be solved in the search for mineral deposits of this type. It is necessary to detect large volumes of rock containing a low percentage of total sulphide mineralization1 and, secondly, to get some idea of the economic significance of this mineralization. The standard geophysical exploration techniques available have a varying degree of application in the search for disseminated sulphide deposits. The electrical methods, and the induced polarization method in particular, are the most successful direct methods, and magnetic methods have indirect application in most situations. This is illustrated by geophysical survey results from several properties in British Columbia
