Dayao-Wangxian region is located in the noutheastern part of Hunan Province, South China. It is a region of high gold
and lead-zinc mineral potential in China. This article shows the successful implementation of GIS technology for gold
nonferrous metal resource prediction in the subtropical monsoon climate and lush vegetation region. In order to enhance
the credibility of ore-finding, three kinds of information (alteration abnormal, lineament) are extracted from ETM+
image data. By making full use of the geological, geophysical, geochemical, and remote sensing data, we predict 9 first
grade and 5 second grade ore-finding prospective areas in this region. About 90% of the known gold, copper and
antimony mineral occurrences are located in these areas.
