Zangge Mining Company Limited

Zangge Mining Company Limited, established in 2002 and listed on the Shenzhen Stock Exchange in 1996, is a manufacturing company focused on the development and utilization of potassium salt and lithium salt resources. Based on the Qinghai-Tibet Plateau, the company leverages the extensive resources of the Qarhan Salt Lake, which spans 724.35 square kilometers. Zangge Mining specializes in the production and sales of potassium chloride and lithium carbonate, which are essential materials used in various industries, including agriculture, new energy vehicles, energy storage, and consumer electronics. The company operates primarily in three business lines: potassium fertilizers, lithium ore resources, and copper resources. Zangge Mining holds significant mining rights in both China and Laos, with proven reserves of potassium chloride and lithium carbonate. It has developed advanced production technologies that enhance the efficiency of resource extraction, particularly in low-grade potassium ore and lithium-rich brine. The company is recognized for its high-quality products, having achieved ISO9001 certification and contributed to national standards in the industry. Through strategic investments, including a stake in Julong Copper Industry, Zangge Mining maintains a strong market position in the raw chemical materials sector.

1. Abundant reserves, continuously injecting growth momentum (1) Potassium fertilizer resources The company holds the mining rights for 724.35 square kilometers of salt lake resources east of the Qinghai Cha'erhan Salt Lake Railway; In February 2023, a subsidiary of the company signed a potassium salt exploration agreement with the Laotian government. The potassium chloride resources of the 157.72 square kilometer potassium salt mine in Ba'ao County, Laos are approximately 984 million tons, and the associated bromine resources are 16 million tons; (2) Lithium ore resources The subsidiary of Zangger Mining obtained the Xizang Mamico Salt Lake Project and the paper version of the Mining License of the People's Republic of China through participating in the subscription of the industrial development fund. The mining area is 115.36 square kilometers, allowing the open-pit mining of lithium, boron and potassium minerals, with a production scale of 364500 tons/year; In October 2024, Jiangsu Zangqing Fund completed the acquisition of 39% of the equity of Xizang Guoneng Mining Development Co., Ltd., which owns the mining rights of the two major salt lakes, Longmucuo and Jiezechaka, in Ali, Xizang, with a total reserves of 3.9 million tons of lithium carbonate and 28 million tons of potassium chloride; (3) Copper resources Xizang Julong Copper Co., Ltd., a joint stock company of the company, has 25.88 million tons of copper resources on record. 2. Leading production technology The company has unique and advanced potassium and lithium resource development technology and production processes, overcoming the difficulties of "poverty, impurity, and difficulty" in China's salt lake resources, and achieving efficient and economic development of low-grade potassium ore and high magnesium lithium ratio salt lake brine. The company's research on the production process and equipment optimization of hot-melt potassium has obtained the Qinghai Province Science and Technology Achievement Certificate. The key technology research and application project for the "one-step" production of battery grade lithium carbonate from ultra-low concentration lithium containing brine has been recognized by the expert committee organized by the Qinghai Provincial Department of Science and Technology and has reached the international leading level. 3. Excellent product quality In the field of potassium chloride products, as one of the drafting units of the national standard for potassium chloride products, the company's potassium chloride products produced since 2005 have successfully passed the ISO9001 national quality management system certification, becoming one of the earliest enterprises in the industry to pass this system certification. Since its establishment, the company has continuously researched and innovated in the production process of potassium chloride. By increasing the particle size of potassium chloride crystals and improving the particle size and quality of products produced by cold decomposition positive flotation process, the company has produced high-quality potassium chloride products with large crystals that are different from traditional processes. With excellent quality and good market reputation, the company's potassium chloride products have successively won the series of honors such as "National Inspection Exempted Product for Product Quality", "China Famous Trademark", and "Top Ten Chinese Potassium Fertilizer Brands". In terms of lithium carbonate products, the company has passed the ISO9001 national quality management system certification and participated in the development of the GB/T23853-2022 national standard testing method for lithium carbonate products produced through the "one-step" salt lake lithium extraction method. The quality of the company's lithium carbonate products has reached the Type I standard requirements of GB/T23852-2022 for brine lithium carbonate, and the product quality is at the leading level in the industry.
