Galvanic and induction electrical geophysical methods are described, and applied to characterize the electrical properties of selected West Shasta massive sulphide deposits and their host rocks at scales less than and greater than 25 ft. The measurements are analysed for their use in differentiating the various rocks and for their correlation with petrographic and geomorphological/climate attributes, and they are compared with other massive sulphide districts of contrasting geological ages. The integrated use of different methods is recommended for effective exploration of the complex West Shasta geology.-G.J.N.
