(Reporter Yang Shu) Since the implementation of my country's new round of mining breakthrough strategy action, with the support of the Ministry of Finance, the China Geological Survey of the Ministry of Natural Resources has joined hands with more than 100 survey units in 27 provinces (autonomous regions and municipalities) across the country to use new mining and smelting technologies to carry out resource reserve re-evaluation of 703 in-produced mines and 1,148 large and medium-sized mining areas. Up to now, the survey units have achieved important results in the re-evaluation of co-associated and low-grade mineral resources - my country's more than 10 mineral resources such as gallium, germanium, indium, gold, nickel, and cobalt have increased significantly.

Symbiotic resources refer to mineral resources that have met the standards and can be used in industrial use after economic and technological evaluation. Accompanimental resources refer to mineral resources that are deposited in the main minerals and have not reached the industrial grade but can be comprehensively recycled and utilized in the smelting process. For a long time, due to the limitation of comprehensive utilization capabilities, some of my country's co-occurring mineral resources have not been effectively developed. Therefore, in the new round of breakthrough strategic actions for mineral exploration, my country has concentrated on a number of comprehensive utilization technology research in order to achieve the economic utilization of a large number of co-incidence and low-grade resource minerals.

Through resource re-evaluation, this round of results shows that the national resources of 12 minerals such as gallium, germanium, and indium in my country have increased significantly. Compared with the retained resources, the increase in new resources of cobalt and rhenium has exceeded 100%, the increase in new resources of nickel and indium has exceeded 30%, and the increase in four new resources of gallium, germanium, vanadium, and potassium salt has exceeded 10%. The resource growth rate of gold, tantalum, rare earths, zirconium and other minerals has also been very significant. Among them, the new gold mine resources exceeds 1,200 tons, which is equivalent to 60 new large deposits discovered; the new vanadium mine resources exceeds 12 million tons, which is equivalent to 12 large deposits newly discovered; the new potassium salt resources exceeds 160 million tons, which is equivalent to 3 new large deposits discovered.

A relevant person in charge of the China Geological Survey said that through re-evaluation work, we can understand the assets of co-associated and low-grade resources, and help mineral exploration breakthroughs and increase reserves and production, and realize that a large number of "did mines" have turned into "active mines", small mines have turned into large mines, and one mine has turned into multiple mines, which will effectively improve the domestic mineral resource guarantee capacity.
