Most gold deposits discovered in Canada in recent years are associated with metallic sulfide mineralization. These relatively small deposits require careful detailing of the weakest of detectable induced polarization (IP) response. This requirement puts constraints on the design and conduct of gold exploration programs using the IP/resistivity method. A study of a suite of known gold bearing deposits using IP/resistivity techniques is presented. These case histories and examples of computer models reflecting these deposits indicate the need to consider carefully the survey parameters when exploring for relatively small low-grade sulfide targets.
