Located in the southwest of the Hatu gold deposit in Tuoli County of Xinjiang, the Haxi gold deposit is a relatively large metallogenic potential deposit discovered in recent years. The orebody is controlled by the NE-trending Anqi fault and its thickness is 0.10~3.42 m, with gold grade being 0.17~64.60 g/t. It mainly occurs in the strata of Carboniferous Telegula Formation and is closely related to basalt. The primary ore of the Haxi gold deposit is divided into two types:altered rock type and quartz vein type. The main ore minerals include pyrite, arsenopyrite, chalcopyrite, gersdorffite, pyrrhotite and native gold. According to the mineral assemblage, the metallogenic process can be divided into two periods, i.e., hydrothermal period and supergene period, and four stages, namely, quartz-sulfide stage, quartz-sulfide-native gold stage, carbonate stage, and oxidation stage. The modes of occurrence of native gold are mainly fissure gold, inclusion gold and intergranular gold with an average gold content of 954.19‰. The particle sizes of native gold are mainly concentrated in 20~50 μm, thus belonging to the microscopic gold.
