Borehole induced polarization method (referred to as borehole IP) is the general term of induced polarization measurements in the borehole. This paper describes the basic principles of the prospecting for blind ore bodies beside and at the bottom of the borehole as well as the application examples using IP/resistivity methods for the surface-to-borehole work pattern. The basic principles of detecting deep blind deposits, the delineation of the ore bodies and the application examples using IP/resistivity method for the borehole-to-surface work pattern are dealt with, and the examples of detecting ore bodies between boreholes are presented. The effect of borehole induced polarization / resistivity method in the exploration of mineral resources is systematically reviewed.
