In assessing the value of mining right,a lot of uncertainties existing in mining activities result in the uncertainties in assessment of the value of mining right.Because Discounted Cash Flow(DCF) method can′t take the uncertainty of mining activities into consideration totally,it can′t be used to accurately assess the value of mining rights value.Based on the achievements in studying uncertainty by using real options theory,a basal real options model assessing the value of mining right was established,and the model has been adjusted.Empirical studies showed that the method of assessing the value of mining right based on real option theory is more effective than DCF method.
