Gelonghui, May 16, 丨 Guang Sheng Nonferrous (600259.SH) said on the interactive platform that since state ministries and departments currently have very high environmental protection requirements for newly built rare earth mines, the procedures related to the Xinfeng mine are still being processed, and construction and production have not yet begun. Due to multiple approval processes involved and the timing is uncertain, the company will strengthen the approval process for various procedures in various aspects such as process design and environmental verification to achieve mine development as soon as possible. The company's shareholder, Dabaoshan Company, has reserves of nearly 400,000 tons of copper resources.
