Abstract TM data because of its multispectral bands and continous spacial coverage as well as good price, is widely used in small and middle scale geological mapping. This project is a case study for using TM data to map surfacial characteristics of ore deposit modle for large scale gold mining district prospecting.The result image is overlayed by 1:10000 geology map, gold bearing vein map, and 1:2000 Cu secondary dispersion halo map. It is conclued that 70% of geological unit is matched, 100% of gold bearing vein and halo are well overlayed.
