The Lishupo has a total resource of 4.3 t Au with an average grade of 4.76 g/t Au
The exposed stratigraphy comprises the Neoproterozoic Lengjiaxi Group, including the Xiaomuping (main ore host) and Huanghudong Formations. Slate and metamorphic sandstone from the Xiaomuping Formation predominantly surface in the central and northwestern mining areas. In the southwestern mining area, the Huanghudong Formation primarily consists of slate and metamorphosed sandstone/graywacke. The major structures of the Lishupo consist of NE/EW-trending faults and WNW-trending ductile shear zones, the latter characterized by quartz-veined slate layers. Locally, the quartz veins are lenticular and exhibit plastic deformation. The 4.5 km long and 2–6 m wide ductile shear zone, dipping NNE at 20–35°, controls the distribution of granodiorite plutons and gold orebodies. NNE-trending faults, with dip angles of 25–40°, extend 2.5–3.5 km in length and are 4–8 m wide. EW-trending, south-dipping faults (20–40° dip angle) in the southwestern mining area extend 3–4 km. The Lishupo magmatic rocks, consisting of medium- and fine-grained granodiorite (zircon U-Pb age: 430.8 ± 3.2 Ma) intruded into the Lengjiaxi Group.
Six gold ore veins (No. I to VI) have been identified at Lishupo. Gold orebodies mainly occur in ductile shear zones, with fewer occurrences along the contact zone between the Lengjiaxi Group and granodiorite intrusions. The orebodies, mainly within sericite-chlorite slates of the Lengjiaxi Group, are concentrated in shear zones characterized by ductile deformation. Quartz veins exhibit a lenticular structure.
Mineralization at Lishupo is delineated into three stages based on mineral assemblages and crosscutting relationships: the quartz-pyrite (Qtz1-Py1) stage, the quartz-dolomite-polymetallic sulfides-gold (Qtz2-Py2) stage, and the quartz-carbonate-pyrite (Qtz3-Py3) stage. Stage 2 is the main ore stage, characterized by polymetallic sulfides and native gold in quartz veins. Stage 1 quartz-pyrite veins are cut by stage 2 veins, containing pyrite (Py1). Stage 3 veins, which contain minimal sulfide minerals, cut through both stages 1 and 2 veins, suggesting that it is the latest stage of mineralization.
