Key Laboratory of Mineralogy and Metallogeny Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou GD China Abstract Huangyeping gold district in Shanxian county Henan province is located in Xiaoshan gold field and Xiaoshan gold field is an important part of Western Henan ore concentrated area. There wildly exposed Mesoproterozoic Xiong'er group faults developed exposed a small Yanshanian acidic rock in it so this gold district is with good prospecting. By through the systemic analysis of the mining geological characteristics and metallogenic environment it is suggested that the superimposed part of fault structure and geochemical anomaly as the prospecting target. After drilling construction 9 gold ore bodies have been discovered in the fractures at depth and Zachieved a real breakthrough in the search of gold mine. With comprehensive analysis mine is not deep degree of erosion most of the ore bodies are not exposed on the surface so there is a good prospect exploration for deep ore bodies. The hydrothermal breccia zone around the rock and the north west fault in the gold district is the favorable area to find gold ore bodies.
