Northern Copper has the largest modern underground mining scale in China's non-coal system, mainly engaged in the extraction, ore dressing, smelting, and sales of copper and other metals. Its main products include cathode copper, gold ingots, silver ingots, and its by-products include sulfuric acid, covering the main industry chain of the copper business. In October 2022, Northern Copper announced its plan to acquire 100% equity of Shanxi Beitin New Material Technology Co., Ltd., held by its controlling shareholder Middle Mountain Group, with an investment of 358 million yuan. Beitin New Material plans to launch the "50,000-ton high-precision copper strip and 2 million square meters of copper foil" project. This acquisition will help optimize the industrial structure of Northern Copper, quickly layout the non-ferrous metal rolling processing industry, promote the innovation and development of copper-based emerging industries, and serve as a key pivot for Northern Copper to transform from traditional mining industry to modern manufacturing industry.
