Newly discovered high-grade oxidized cobalt ore spot in the central Yunnan Province
There are a number of reports of cobalt deposits,including magmatic,hydrothermal,weathering,and sedimentary types in SW China,particularly Yunnan Province,which makes this region as a critical player in cobalt resource exploration.Recently,the authors identified a new type of cobalt ore spot in the central Yunnan Province.This newly discovered cobalt ore spot exhibits pink-peach red cobalt oxides in Proterozoic silicified low-grade metamorphic rocks and is controlled by structure.The cobalt minerals,occurring as disseminated,fine-veined,and clustered forms,coexist with quartz,mica,apatite,carbonate minerals and sulfides.They are mainly erythrite with minor heterogenite.Chemical analyses of five collected samples yielded an average cobalt content of 0.23％,with a maximum value of 0.92％.Notably,the samples also display enrichments in elements such as copper,arsenic,and nickel.Analyses of two further grooved samples(1.5m/segment)revealed cobalt contents of 0.15％and 0.22％,respectively.The finding of this high-grade oxidized cobalt ore spot has significant theoretical implications and regional cobalt exploration.
