The Baiyinnuoer Zn–Pb–(Ag) deposit (32.74 Mt ore with grades of 5.44% Zn, 2.02% Pb, and 31.36 g/t Ag), located 5 km north of the Haobugao deposit, is the largest Zn–Pb deposit in northern China (Jiang et al. 2011; Figs. 1 and 2). Two ore-bearing belts (Southern Belt and Northern Belt) have been discovered in the Baiyinnuoer area.
