Abstract Statistics based on HS26 abnormal area of 90 drill holes and 3 312 samples of polarizability data show that the polarization rate of metamorphic and intrusive rocks in this region is very low, alteration only slightly changes the polarization rate, but mineralization causes significant increase of polarization incidence, so that the high polarizability is indicative of high mineralization degree. A comparison between the polarizability and metallogenetic elements nickel, copper and cobalt content in the profile distribution reveals the corresponding relationship between the high polarization rate of abnormal center and metallogenic element concentration center, and it suggests that the high polarizability distribution area is the reflection of the orebody. Accordingly, the authors further analyzed the spatial distribution of the polarizability and looked for the end of the closed high polarizability anomaly. It is pointed out that further exploration of HS26 anomaly area should cross diabase dikes and continue to the southwest side of the metamorphic rocks of the coverage area, and it should begin from the end of the closed high polarizability anomalies as well as from ZK2305 and ZK2303 holes and extend westward to trace the deep orebody.
