The New England Orogen(NEO)is located in East Australia. Due to the numerous copper polymetallic deposits or ore spots and the complicated evolution history of tectonic activity, NEO shows the high exploration potential for copper polymetallic minerals, even large-sized deposits. The airborne electronic anomalies were delineated by airborne time-domain electromagnetic method. Based on the aerial electronic anomalies and using a method called "Seeking Common" with the known copper polymetallic ore spots, the authors performed the optimization and evaluation of copper polymetallic minerals in an exploration license within quite difficult topographic conditions for ground exploration in NEO. Using the airborne time-domain electromagnetic method, the authors rapidly and effectively determined and optimized nine copper polymetallic exploration targets. Those targets were classified into three levels: Level Ⅰ, Ⅱ, Ⅲ. Finally, and there were three, five and one targets for Level Ⅰ, Ⅱ, Ⅲ respectively. In a word, the work completed in this paper is expected to provide a referable case for rapidly and effectively conducting optimization and evaluation of copper polymetallic minerals in some special areas within difficult topographies for ground exploration both in China and abroad.
