The Group attaches great importance to the reserve and development of mining resources, always follows the national policies and regulations on mining resources, and always attaches importance to environmental protection. At present, the Group reserves lead-zinc mines, coal mines, molybdenum mines, quartz mines, gold mines, graphite mines, granite mines, marble mines, phosphate mines and lead-silver mines in many places throughout the country. At present, the Group's domestic mining development momentum is very good, and there is still a lot of room for improvement in the future. The group will take advantage of the current favorable opportunity to accelerate the pace of mining mergers and acquisitions, integrate its own original mining resources, form a new mining group and eventually go public. At the same time, the group seized the favorable opportunity of China-Africa friendly development and actively entered African mining industry. It has invested in copper mines and smelters in Zambia and the Democratic Republic of the Congo as a strategic reserve of domestic resources.
