The bulk of Cu-Ni ore deposits in East Tianshan, making up a large portion of Ni resources in North Xinjiang, were concentrated in the east of East Tianshan (the Huangshan- Jing'erquan region) (Feng Yanqing, et al., 2017), while no any analogue was discovered in the west of East Tianshan until the Lubei Cu-Ni (Co) ore deposit (90°21'E, 42°10rN) was identified by Xinjiang Geological Survey in 2014. The Lubei Cu-Ni (Co) ore deposit is a medium- to large- sized deposit with Ni and Cu grades in the range 0.2%- 7.76% and 0.2%-2.30%, respectively. This work has initiated the prospection for a large-sized Cu-Ni ore deposit in the west of East Tianshan.展开更多
