Mineral resources are in the earth's crust, which can be developed and utilized in accordance with the geological law. The distribution of mineral resources in the world is not balanced and the large and medium-sized deposits to the important metallogenic region with the characteristics of aggregation. To copper mine as an example, the global 138 copper metal more than 500 million tons of copper deposits, in 86 of the circum Pacific metallogenic domain and Tethyan metallogenic domain for 20 and 11 Laurasia metallogenic domain distribution; metallogenic domain of Gondwana distribution of 21 (Figure 1).

Therefore, on the famous metallogenic zone, existing production mines surrounding or in recent years have find breakthrough in ore area looking for mine risk is relatively low, find the probability of rich and large ore is higher. It is a constituency project an important basis.
