Construction of investment evaluation model and decision research for mining projects
Mining investment projects are characterized by a great deal of investment,long development period,high risk,significant technical complexity,and numerous uncertainties.To provide investment ideas and methods,and enhance the scientific level of decision-making for mining investors,this paper offers a comprehensive analysis of mining investment projects,including their classification and characteristics,overall investment logic,and investigation logic of mining project.On this basis,a set of key models and decision reference standards for mining investment evaluation are established,and six evaluation decision standards and details are developed for mining enterprises,including legal compliance,complete legal licenses,high-quality mining rights resources,suitable mining conditions,high infrastructure utilization rate,and good surrounding environmental policies.According to different types of mining investment projects matching the corresponding decision criteria,using the weighted score method for each project in accordance with the details of the decision standards.Mining projects are categorized according to scores into four grades:high-quality(100-85 points),sub-optimal(85-70 points),general(70-50 points),and poor-quality(less than 50 points).It is suggested that high-quality and sub-optimal class mining projects can be considered for investment,general class mining projects should be invested with caution,and poor-quality mining projects should not be invested.At the same time,a mineralization scale analysis model is constructed to estimate reserves,and a mining right value evaluation model is further established to calculate the reference price for mining right investment.Combined with project class,it provides scientific decision basis for mining project investment,reduces investment risks,and improves investment return rate.
