The Yunnan Boka gold deposit is located in the northwestern part of Dongchuan District in Yunnan Province. Its orebodies are produced in the metamorphic rocks in the Kunyang Group in the ancient boundary of the northern part of the “Kangdi-Dianpin” Yunnan section (Hao et al., 2009). Yunnan Boka Gold Mine is located between the Jinsha River and Xiaojiang. It is located on the western margin of the Yangtze block and east of the Deqin-Menglian Permian volcanic belt. In the mining area, the Middle Proterozoic Kunyang Group metamorphic rocks are exposed, while the periphery is covered by Sinian and Paleozoic and Mesozoic strata. Kunyang group distribution of the United Party group, due to the people group, falling snow group. The United States party group located in the eastern part of the mine, the main lithology of light gray slate, local white folder
