thickness of about 2 to 16 meters, a lithium oxide grade of 0.10% to 1.02%, and an average grade of 0.30%

I'd say, more likely they found a large very low grade lithium deposit.



World-class lithium resource base discovered in Yunnan

The reporter learned from the Institute of Geochemistry of the Chinese Academy of Sciences on the 3rd that China's new type of lithium ore prospecting and metallogenic theory has made a major breakthrough, and found a world-class lithium resource base in Yunnan. It is predicted that the base lithium resources will exceed 5 million tons.

China is currently an importer of lithium resources. From 2011 to 2015, the dependence on foreign countries reached 80%. Finding new lithium resources has become a top priority. To this end, the national key research and development plan project - the chief scientist of the deep exploration technology demonstration project of the rare mineral resources base, and the researcher of the Institute of Geochemistry of the Chinese Academy of Sciences, Wen Hanjie, proposed the new deposit type and new mineralization model of the "carbonate clay type lithium deposit".

According to the newly established metallogenic model, the research team discovered a potentialgiant lithium resource base in the Yuzhong basin of Yunnan. The ore body is enriched in the Lower Permian inverted stone group and is a set of “Land-Margin” sedimentary rocks. Floor. The project team conducted a demonstration of scientific research in two target areas delineated in this area. The results of the engineering survey indicate that the lithium-rich ore deposits in this area are stable in distribution, with a thickness of about 2 to 16 meters, a lithium oxide grade of 0.10% to 1.02%, and an average grade of 0.30%. A total of 7.2 square kilometers of research and demonstration zones are available. The amount is about 340,000 tons, reaching a large scale. Experts predict that lithium resources in the central region will exceed 5 million tons, which will form a world-class lithium resource base.

The project has passed the mid-term evaluation and on-site inspection at Kunming University of Science and Technology from May 30th to 31st. According to reports, carbonate carbonate-type lithium resources have broad prospects in China due to the large-scale carbonate-type clay rocks in other regions. (Reporter Zhao Hanbin).
