The Oyu Tolgoi deposit, one of the largest porphyry Cu(Au)deposits in the world, is characterized by high copper and gold reserves, high grade, wide range and large scale mineralization of the orebody. China- Mongolia border extends for 80 km,which belongs to China's"One Belt, One Road" project and hence is one of the important directions for the going out policy of China's enterprises. On the basis of the information collected and analyzed by the authors, it is considered that North Heruga region,Javkhlant region, West Hugo deep region, West Hugo deep region, Ulaan Khud northern region are five strategic targets. On such a basis, the authors set up a metallogenic model. The authors hold that the Oyu Tolgoi deposit is located in the metallogenic belt which extents along the Kazakh-Mongolian magmatic arc to the two ends. In the west, the belt extends through the Tuwu copper deposit of Xinjiang to the Kounrad porphyry copper deposit and another porphyry copper deposit in the territory of Kazakhstan; in the east,it extends to Duobaoshan and Tongshan area within the territory of China.
