Comprehensive 5-direction IP logging is one of the important methods for exploration of sulfide type ore deposits. Blind and concealed ore bodies can be found by using its advantage of high SNR and on the premise of understanding the physical parameters. The practical example of the exploration of a Cu-Fe polymetallic deposit in Houa Phan Province of Laos shows that the 5-direction IP logging curve is in accordance with the drilling result. The enrichment sectors of pyrite and chalcopyrite are all associated with high polarization anomalies, and a comprehensive analysis can determine the position of the blind ore body. This exploration is a successful case of discovering hole bottom blind ore body under the guidance of 5-direction IP logging.
