Mesothermal vein-type gold deposit, hosted in a sequence of Early Carboniferous volcanic-sedimentary rocks outside of the contact zone of the Baogutu stock. The ore bodies are controlled by NE-trending faults and fractures, and consist of quartz-sulfide vein stockworks which formed in three paragenetic stages: (1) coarse-grained quartz–sulfide veins, (2) gold-bearing fine-grained quartz–sulfide veins, and (3) native antimony-bearing calcite–sulfide veinlets.

The deposit consists of four isolated vein clusters (ore blocks) within an area of about 10 x 10 km, west of the Baogutu copper deposit. The mine is working blocks 3 and 4 which are only a few hundred meters apart.


Note:
Not to be confused withe the Baogutu porphyry copper deposit, which comprises associated high temperature vein-type gold mineralization within the contact zone.
