Abstract: Copper, as an important strategic mineral resource, is one of the most critical scarce minerals. southwestern China geological background is superior for copper ore prospecting with big resource potential, after 10 years national survey, discoveries and progresses have been fundamentally changed China's copper resources strategic distribution pattern. By accelerating copper resources exploration in southwestern China, tightly focusing on the important metallogenic belt and the main types of copper deposits, it's necessary to constantly improve the exploration degree as soon as possible thus to realize a new round of major breakthroughs, and greatly increase the reserves of copper resources, it plays an important role of domestic copper resources supply insurance
