| Abstract:The Xingnong lead-zinc deposit in Ji’an city lies in the southwest of the Yalu River polymetallic mineralization belt. The geological condi鄄
tions of this area are favorable for metallgenesis due to its well developed structure and widespread igneous rocks. The NE trending fault parallel to the
Yalu River is the main ore-controlling structure which dictates and hosts ores. The two structural alteration zones are filled with quartz veins due to activity
of thermal liquids where ore concentration occurred in favorable positions. Till now, five Pb-Zn ore bodies on the surface, and four hidden Pb-Zn bodies
and one hidden Au body at depth have been found. These ore bodies are present in veins, with obvious characteristics of thinning out and reappearing,and
lateral change. Based on regional metallogenic regularities, ore-controlling geological conditions and the ore bodies discovered at depth discovered, it is
confirmed that this area has a good prospecting potential of multiple metals at depth and on periphery.
