| 摘 要： | 为准确、客观估价丁家林金矿区探矿权价值，根据矿区地质报告中提交的储量级别、矿体控制程度和工程质量，确定了基础和可采储量、生产规模、矿山服务年限、贴现率、有关实物工作量等6项参数。综合运用贴现现金流量和重置成本法对探矿权进行评估，对达到详查程度的基础储量采用贴现现金流量法，控制程度低的资源量采用重置成本法，二者之和综合反映探矿权的价值。此方法适用于地质工作程度不均衡矿区的探矿权评估，贴现现金流量法要充分考虑储量的可信度和获利临界品位．重置成本法关键是准确确定有关的实物工作量。

| Abstract: | Based on the grades of reserve,the controllable degree of orebodies and the quality of engineering,which presented in the geological reports on the mining areas,six parameters (basic and proved extractable reserve, production capacity,years of mine,discount rate,working amount related to objectives and so on).have been determined to evaluate the exploration rights of Dingjialin gold mining areas accurately and objectively.By combining two methods of Discounted Cash Flow Method and Reestimated Costing Method to evaluate the exploration rights,the former is adopted to basic reserve by general exploration and the latter to resource which is lower controllable,respectively.The two methods can present the value of exploration rights synthetically.The way is suitable to evaluate the exploration rights of mining areas where the degree of geological works is uneven.The method of Discounted Cash Flow should consider the confidence of reserves and the profitable critical grade fully.The key to Reestimated Costing Method is to determine the amount of object-working accurately. |
