Abstract The Buobuza area selected for the study is located in the Qiangtang Plateau hinterland in the western part of the Bangong Co-Nujiang River metallogenic belt. The authors carried out an overall survey of regional geochemical exploration. A comparison of different grades of stream sediment samples shows that -10~+40 mesh is the best sampling fraction here; rarefied test study shows that more than 1/4 km2 sampling density is valid for discovering a large deposit. According to the -10~+40 mesh stream sediment results of the overall survey, the authors predict that the periphery of the Duobuza ore district has the potential to find large or superlarge copper deposits, particularly in the upper reaches of the Rongna ditch.
