en.Wedoany.com Reported - China's Guocheng Mining Co., Ltd. (000688.SZ) announced on July 17, 2026, that its controlled subsidiary, Sichuan Guocheng Lithium Co., Ltd., plans to sign a "Spodumene-Battery Grade Lithium Carbonate Entrusted Processing Contract" with Tianjin Guocheng Trade Co., Ltd., a wholly-owned subsidiary of its controlling shareholder, Guocheng Holding Group Co., Ltd. Under the contract, Guocheng Lithium will process approximately 48,000 tons of spodumene concentrate provided by Tianjin Guocheng into battery-grade lithium carbonate that meets the delivery standards of the Guangzhou Futures Exchange.
Guocheng Mining Co., Ltd., established in 1997 and listed on the main board of the Shenzhen Stock Exchange in the same year, primarily engages in non-ferrous metal mining, selection, and comprehensive resource recycling. Its main products include zinc concentrate, lead concentrate, copper concentrate, titanium dioxide, and sulfur concentrate. After Guocheng Group took over in 2018, the company gradually built three major industrial clusters: "lithium ore and lithium salt new energy, precious and non-ferrous metals, and specialty titanium chemical circular economy." In terms of lithium resource layout, its key investee, Maerkang Jinxin Mining Co., Ltd., owns the Dangba spodumene mine, which has identified a total of 1.1207 million tons of lithium oxide resources, making it the largest granite pegmatite-type lithium deposit discovered in Asia to date.
Sichuan Guocheng Lithium Co., Ltd. is a controlled subsidiary of Guocheng Mining. On July 13, 2026, the first phase of Guocheng Lithium's annual 200,000-ton lithium salt project was officially put into operation. The first phase, with an annual production capacity of 60,000 tons of battery-grade lithium carbonate, has completed commissioning and trial runs, achieving stable product quality. Located in the Deyang-Aba Ecological Economy Industrial Park, the project adopts industry-leading low-carbon purification technology, and its products are widely used in power batteries, energy storage, and high-end electronic materials. The overall project plans an annual output of 200,000 tons of basic lithium salts, constructed in three phases. Once fully completed, it will become the largest single-site lithium salt production base in China.
Under this entrusted processing contract, Tianjin Guocheng Trade Co., Ltd., as a wholly-owned subsidiary of Guocheng Group, the controlling shareholder of Guocheng Mining, constitutes a related party with Guocheng Mining. The contract stipulates processing approximately 48,000 tons of spodumene concentrate (on a dry basis, equivalent to 6% Li2O content), with the specific quantity subject to actual delivery, and processing fees settled at fair market prices. Guocheng Mining stated that the transaction pricing follows principles of market fairness, justice, and transparency, and does not harm the interests of shareholders, particularly minority shareholders.
The signing of this entrusted processing agreement will help Guocheng Lithium fully leverage the processing capacity of its already operational first-phase 60,000-ton/year battery-grade lithium carbonate production line, further closing the industrial chain loop from spodumene ore to battery-grade lithium carbonate.
