Formerly known as Nanjing Lead Zinc Silver Mining, the company was founded in 1957 with the largest Pb-Zn deposit in East China. The lead and zinc reserves have reached nearly 20000000 tons, including sulfur, manganese, gold, silver and other useful elements. When the mine was constructed at first, the original fixed asset was only 177900 yuan and the total number of employees was 618 people. However, for nearly fifty years, motivated by the spirit of “hard pioneering work, exploration forward”, the company insists on path of innovation and accumulation relying on its own strength, which expands the enterprise scale, improves the production capacity, increases the technical level rising and obtains greater economic benefit.

In 1970s, the company realized the transition from surface mining to underground mining; in 1973, the annual processing capacity was 30000 tons and at the end of 1979, it reached to 75000 tons by the third technological transformation and 200000 tons in 1994 by the second technological expansion.  

In May 2001, in order to speed up the development pace, the company carried out the reform of property right and became a private company. It takes less than five years to complete 350000 tons / year mining technological expansion project based on its own strength, design and construction. As a first-class mine with strong economic strength at the same time, the company diversified development path and becomes a multi industry enterprise consisting of "high-tech manufacturing, non-ferrous metal mining industry, modern service industry, wood industry and real estate". In 2006, the company achieved 1.3 billion sales revenue and 250 million yuan profits and taxes and has developed into a new company with economic scale, research and development capabilities and diversified products. In view of the development and scale of the company, in the beginning of 2007, the holding group was registered. At present, the group has wholly- owned, holding or joint stock more than 20 companies.

In recent 20 years, the group has experienced three stages including major technical transformation, reform and upgrading of the enterprise. It has become a group integrating“non-ferrous metal mining industry, high-tech industry and modern service industry”from a single resource-based enterprise and the total economic volume ,overall benefit and income level have greatly increased.
