Data sources: Pajonal-El Abra, Los Picos-Fortuna Cu (LPF) and Chuquicamata from Ballard et al. (2002); Cerro Corona Cu-Au (CC) from Hattori et al. (2017); Baogutu Cu (BG), Borly Cu-Mo (BL), Tuwu-Yandong Cu-Au (TY), Koksai Cu-Mo (KS), Erdnet Cu-Mo (EN), Aktogai Cu-Mo (AG), Kounrad Cu (KR), Nurkazghan Cu (NG), and Bozshakol Cu-Mo (BK) from Shen et al.
