Medium-scale shear zone and quartz vein type gold deposit. Deposit minerals vary from disseminated and fine veined to brecciated and banded. Their textures are idiomorphic, hypidiomorphic-xenomorphic and metasomatic replacement. Three zones occur, from SW to NE: (1) the main deposit in the first zone occurs in a structurally altered zone between basal schist, quartzite and marble of the Huashan Formation and an upper, thick dolomititic marble of the Zhenzhumeng Formation; (2,3) deposits in the second and third zones occur in a structurally altered zone in thick dolomitic marble of the Zhenzhumen Formation. The zones vary from stratiform to lenticular, and single zones may range from several tens to a hundred meters long. Wide-spread carbonate and silica alteration is associated with the deposit. Other important alterations are arsenopyrite and pyrite.
The deposit currently has proven reserves of 11 t of Au with an estimated further 20 t of potential Au resources at an average grade of 6.59 g/t. A total of 79 orebodies have been identified in three distinct mineralized belts. Lode No. 1 is the largest and most representative of the orebodies, which occurs in the mineralized belt I. The gold vein in lode No. 1 is 386 m long and 0.80–25.34 m thick, dips at 40°–50° toward 300°–330°, and contains Au grades of 1.58–17.66 g/t (mean, 9.00 g/t). Lode No. 2, the second largest gold vein, is situated to the northeast of lode No. 1 and is 410 m long and 1.02–6.89 m thick, dips at 60°–80° toward 120°–140°, and contains Au grades of 1.86–11.53 g/t (mean, 5.81 g/t).
