1 Regional Geological Background The copper mine is located about 40 km away from the 207 ° direction of Huili County. The tectonic location of the copper deposit is located in the southwestern margin of the Yangtze platform and in the Panxi rift to the east of the central-southern axis of the Kangdi-Yunnan axis. The exposed strata in the area from Lao to Xinxian are the former Member of the Pre-Sinian Conservative Group (Pt_2h) Tong’an Formation (Pt_2t) Lijuehe Formation (Pt_1l) Fengshan Formation (Pt_1f) The Tianbaoshan Formation (Pt_1tn) Central Plains Yimen Group (J_2y) Upper Triassic Baigewan Bay (T_3bg) and other formations. The structure of the mining area is rather complicated and the folds are developed. The main trend is north-south direction, and the fold of the main area is the estuary anticline. Faults mostly SN, the main fault structure
