Cerro Vanguardia is a gold-silver mine located in the central steppe of Santa Cruz province, Argentina. The deposit consists of several veins 3.5–10 m in width and 19 km in length. Mining is currently carried out by means of open pits averaging 100–200 m in depth and, more recently, underground developments. More than 50 open pits are expected to be developed during the lifetime of the project. This work presents the stability assessment carried out on pit Osvaldo Diez cutback 7, which comprises limit equilibrium analysis (LEA) and finite element modelling (FEM).
