Abstract: Ever since CHIM has came into being, it's mainly used in detailed exploration and anomaly validation. Constrained by heavy equipment, high cost and low efficiency, CHIM is not suitable for large-scale exploration. Through several experimental attempts, CHIM has been innovated into a power supply under low voltage "dipole". Satisfactory application has been achieved in Taifu gold mine in Heng County, Guangxi with improved CHIM. Also it was adopted experimentally during general prospecting at 500 m × 500 m spacing at Jinwozi-210 gold deposit in Xinjiang. It indicated that the improved CHIM is feasible and available in search for minerals. In conclusion, improved CHIM can be not only used for detailed exploration and mineralization validation but also in general prospecting effectively.
