The advantages of the bilateral axial poledipole array lie in its considerable data collection capacity, strong IP signal, great penetration depth, high exploration precision and high efficiency. The poledipole array is an nonsymmetrical array which gives rise to relatively complicated anomalies in the pseudosection. In a working district within Bairin Left Banner of Inner Mongolia, the authors used GDP32II geophysical digital receiver made by Zonge Company and bilateral poledipole time domain IP sounding to explore silver and leadzinc polymetallic ore deposits and employed drilling inspection of the 2D inversion of geoelectric section for common shatter zones and polymetallic mineralization. It is shown that this method is very ffective in oreprospecting work of the survey area.
