摘　　要：矿床地质品位是评判矿山项目价值的重要依据,特高品位值对贵重金属矿和有色金属矿的资源量估算结果影响较大,进而会影响到项目估值,因此是项目并购中需要重点关注的部分。目前行业内有采用均值倍数以及概率图等不同方式来确定特高品位,两种方式两种方法各有特色,本文通过对非洲某金矿的资源估算研究,分析采用这两种特高品位处理方法在估值结果上存在的差异,为中资企业的海外矿业项目并购提供参考。The mineral grade of a deposit is an important yardstick for the evaluation of a mine. The ultra-high-grade value has a major effect on the resource estimation of precious and non-ferrous metallic mines,and in turn affects project valuation,hence a key issue to consider in project acquisition. Current practices of handling ultra-high-grade values include average multiples and probability plot.Each of the two has its own merits. This paper is a study of the two methods by comparing their estimation results,providing a reference for Chinese investors in acquiring overseas mines.
