Mine scheduling requires input variables such as geological model and economic values in order to deliver an optimal production schedule. Geological uncertainty in grades, metal and material types cause a difference in the performance of forecasted long-term production scheduling. The risk analysis of a production schedule given geological uncertainty assists the potential performance of robust mine planning and risk management. The Risk Analysis Tool (RAT) uses as input the mine production schedule and the set of stochastic simulations of the mine deposits. The workshops show how the risk analysis is carried out using the available RAT in COSMO Stochastic Mine Planning Laboratory. Data from a copper Martian mine is used to describe the use of the software.
