China Aluminum International: Subsidiary Signs an Overseas Salt Lake Lithium Extraction Project Design Contract

China Aluminum International stated that recently, Changsha Nonferrous Metallurgical Design and Research Institute Co., Ltd., a wholly-owned subsidiary of the company, signed an engineering design contract with Hong Kong CBC Investment Co., Ltd. (Brunp Recycling) for the lithium extraction construction project of the Uyuni Salt Lake in Bolivia with an annual production of 25,000 mt (LCE). At present, the company is not involved in the investment business related to lithium extraction from salt lakes and does not directly produce lithium materials. It only provides technical design, consulting and engineering construction services for lithium enterprises. This business will not have a significant impact on the company's performance.
