The tectonic position of Dongwujiazi gold deposit is in the middle section of the north margin of North China Craton, Chifeng-Chaoyang gold mineralization concentration area. In the north, it separates the Inner Mongolia-Xing’an Fold-orogenic Belt from the Chifeng-Kaiyuan deep fault, and its south border with Yanshan subsidence zone is the Lingyuan-Beipiao deep fault. The NW trending faults are the main ore-hosting structure in the mining area, the spessartite in the vein rock is greatly related with the mineralization. The natural type of the ore is quartz-vein type, the sulfide in the ore is mostly pyrite, while chalcopyrite and galena are in the second place, noble metal minerals include native gold and hessite. The wall-rock alterations include silicification, sericitization, and carbonatization, the zoning of the alterations is obvious.
