     nowadays, economic uncertainties perform indispensable role in mining evaluation projects, so that, evaluation of a mining project without considering the available uncertainties is incorrect and unreliable. metal price uncertainty and operating costs uncertainty are the most important parameters in economic uncertainty. numerous research works have been carried out for price uncertainty, but there is no noticeable research on the simultaneous effects of operating cost and price uncertainties on the evaluation process. for solving this problem, a new evaluation method – pyramid technique – was developed based on the binomial tree method. pyramid technique can evaluate the mining projects under the situation of multiuncertainties. in this research, for determining the efficiency of the pyramid technique, the net present value of the cayel copper mine was computed under economic uncertainties. finally, the achieved results were compared by the results of the other evaluation methods such as descanted cash flow. it is concluded when uncertainties are considered by pyramid method, the mine evaluation suggests greater and more reliable net present value.
