Abstract

Sungun copper mine is one the most important mines. It is in the final stage of development. The rate of production of this mine is 7 Mt and 14 Mt in the first and second phase, respectively. Average grade of the deposit is 0.6% and the grade of mill concentrate would be 30%. Feasibility study and mine design are carried out on the basis of several techno-economical and financial variables. Estimation of these variables is made under uncertainty condition of basic data and therefore, sensitivity of output of the project should be evaluated for these uncertainties.In this research work, at first step, with the help of Excel and COMFAR software’s for project economic and financial analysis, a model was developed. And then the model was run considering scenarios for a certain variation of expected value of variables. Finally, it was concluded that INTERNAL RATE OF RETURN is affected more by concentrate price comparing to other relevant factors. In this regard, mill recovery plant, exchange rate, capital costs, mine overall slope angle and operational costs can be considered in the next degrees of importance.
