Huashugou gold mine was found，and the new understanding of gold mineralization was put forward basis on the geological survey in four 1/50000 regional map of Chahar right Qianqi，etc，by using the geochemical samples exploration，geological mapping and the comprehensive prospecting methods.Field geological study found that NE and nearly EW trend faults control the distribution of the abnormal faults and the outspread of the surface structure alteration belt and iron manganese ore body in the mining area.The surrounding rock and mineralization alteration are mainly silicide，potassium，sericitization and along the fissure filling iron manganese ore and limonite.Selecting the prospecting target area by comprehensive prospecting method，Huashugou anomaly area were reduced from 28.8 km² to 3.6 km²，help to better looking for gold deposit.By using stream sediment and soil measurement method，anomaly elements were tested，and according to the enrichment coefficient，the results showed that Ag，Pb，Zn，As，Sb，W，Bi，Mo，etc.，has strong enrichment in Huashugou groove rock，and closely associated with mineralization，its surrounding rock，the Jining Group are enrich and strong enrich in Ag，Pb，Au，Cu，As，Sb，W，Mo，etc.，show that magma activity provides a ore-bearing hydrothermal mineralization，and hydrothermal metasomatic with surrounding rock，causing much metals such as gold and silver enrichment in the favourable area.Combining 1/10000 geological mapping methods and soil measuring，further anomaly examination and evaluation was conducted，found multiple ore sample content with cutoff grade，obvious abnormal thick concentrated heart and zoning.The implementation of exploratory trench engineering expose and mark out 2 gold orebodies，the distribution feature，composition and ore-controlling factors have been identified，indicating that the area has good ore prospects.
