Granitoid-related gold deposit, hosted in the Jiaojia-Xincheng fault zone at the contact between Linglong granite and Guojialing porphyritic granodiorite. Disseminated and stockwork-style mineralization occurs in the footwall of the fault. The lenticular ore bodies are parallel to the main fault plane. Ore shoots dip steeply to the southwest.

Gold resources totaling 200.7 t, reserves of 59.6 t, and a grade of 3.38 g/t, it ranks as the fourth largest gold mine in the Jiaodong region and the sixth in China, boasting a cumulative gold production exceeding 100 t. Furthermore, the Xincheng gold deposit is also abundant in other important mineral resources such as silver, copper, sulfur, cobalt, and chromium, all of which have significant economic potential for exploitation and utilization.
The Xincheng gold deposit is a typical example of “Jiaojia-type“ gold mineralization, with orebody I being the most significant within the mining area. This orebody comprises disseminated and stockwork-like ore types, primarily occurring within the pyrite–sericite alteration zone adjacent to the footwall of the main fault. The orebodies are hosted within hydrothermal alteration zones, and their distribution is tightly controlled by the Jiaojia fault. They are mainly located at changes in the attitude of the Jiaojia fault zone, trending northwest with relatively stable thickness. They exhibit a stratiform or layered structure with branching and merging phenomena.
The mineralization process is divided into four distinct stages: the quartz–sericite–pyrite, quartz–pyrite, quartz–polymetallic sulfide, and quartz–calcite–pyrite stage. Notably, the second and third stages are the primary gold mineralization stages.
