The study district was formerly considered to be a district possesing almost exclusively iron and copper deposits. Insufficient attention was paid to the search for gold ores, although this element was observed in known deposits. Using trace gold test technique, i.e., chemical spectroscopy with detecrion limit of 0.3 ppb, regional geochemical prospecting (stream sediment survey) has delimited two high gold terrains with Au >2ppb (Maocun-Binshan-Wuxian and Jiazhen) and 22 local gold anomalies, as prospective sites in search for goposits, In addition to known gold-associated occurrences, ten places are supposed to to be quite promising in gold prospecting, of them, two have already been proved to contain a middle-sized gold deposit and two good gold occurrences. Regional geochemical data of gold have been changing the attention of geological work in this study district. The regional geochemical distribution of gold assumes combined zonation trending northeasterly in the nosthwest part and northwesterly in the southeast part, with alternating high and low values which show an increasing trend of intensity from north to south. All this implies that gold distribution is controlled by NE and NW trending structures. The local gold anomalies, lying at the intersections of these two sets of structures, are distributed like chessboard. This paper indicates that Jiazhen and southern Binshan are two most favourable sites for gold prospecting in the study district.The Yenshanian intermediate-acid intrusive bodies related to iron and copper mineralizations have been evaluated for their gold potential. It is indicated that the F rock body, formerly regarded as nonproductive, is likely to contain gold, as is supported by the detection of Yicun and Geng;un gold occurrences.
