The Longkou gold deposit is located in the footwall of the Guocheng Fault, within secondary fault zones. Gold orebodies are mainly hosted in the marble unit of the Jingshan Group and the Muniushan monzogranite. Representative orebodies L22 and L20 are approximately 260–280 m in length, 0.90–24.42 m in width, and 1.00–3.60 m in thickness, with an average grade of 2.67 g/t. The orebodies strike NE–SW, dip SE, and have dip angles ranging from 14° to 41°.
