In 2006, the State Council's Decision on Strengthening Geological Work was promulgated, and the state established a geological exploration fund (working capital). Unless otherwise stipulated by the state, the mineral resources identified by the fund shall be sold in the market, and the income (after deducting a certain proportion of the income reserved for geological prospecting units) shall be divided by the central and local governments in proportion (2: 8), which is mainly used to supplement the geological prospecting fund and realize its rolling development. Take it down from the mine and use it in the mine.
