Physicochemical methodshave been widely used for locating concealed ore deposits in China and elsewhere．TheMashiba deposit is a typical stratabound deposit in the Luflian dome tectonic metallogenic belt in Zambia. The host beds are the lower part of the RL6 mudstone schist and the upper part of the RL7 glutenite, which are characterized by excessive oxidation zone to sulfide zone from shallow to deep. In order to explore the deep copper sulfide extension，in this paper， geophysical (IP polarization，high density resistivity and AMT) and geochemical (soil measurement， partial extraction measurement) methods are used. Three profiles were selected for the comparative study of geophysical and geochemical exploration methods. Geophysical exploration results show that the sulphide ore has low resistance (50~300 Ω·m)，high (2. 5%~8. 0%) abnormal amplitude frequency characteristics. The high density resistivity method and AMT resistivity isoline can clearly reflect the form of basement and non- ore- bearing strata at the bottom of RL7 which is a good indicator for ore prospecting．Geochemical exploration results show that the related elements of Cu are Ag and Biand Cu- Ag- Bi element combination is formed in the process of sedimentary mineralization. The oxidized ore near the surface shows a “hump” high value anomaly，while the sulfide ore in the deep shows a “partial front” weak anomaly. Partial extraction shows that Cu，Co and Bi elements mainly exist in the form of second- phase Fe- Mn (hydrogen) oxide phase．On the basis of the results of the effectiveness test of the method，the comprehensive prospecting model of the deposit type is summarized and established， the deep prospecting target area is delineated according to the geophysical and geochemical anomalies，and the two- layer industrial orebody is verified by the later drilling engineering．IP method， high density〖JP〗 resistivity method，audio magnetometer method, soil survey and partial extraction survey are the combination of methods to realize the economic and rapid prospecting of strata- controlled copper depositsand also provide a reference for the prospecting of the same type of deposits within the scope of the ore field．
