The copper mine is located in the north-eastern margin of the Junggar basin, south of the Altay Piedmont zone. The terrain is flat, weakly cutting, only slightly undulating hills. The development of magmatic rock in the area is controlled by the Ertix fault, which trends roughly northwest. The main rocks are diorite and diorite porphyrite. The intrusion rock occurs as stock, with quartz veins distributed widely. Strata in this area belong to Junggar Formation and main strata at bottom are Devonian System, Carboniferous, Tertiary. Intrusive rocks are widely distributed in the southern part of the study area, and formed at Yuhaixi period, Yanshan period. Irregular apophysis and dike rocks occur mainly along the fracture structure. Diorite, diorite porphyrite, pyroxene diorite porphyrite, horns, glint conglomeratic diorite porphyrite, quartz diorite, etc.
