Abstract:

“Prognosis model”is considered as bridge to combine metallogenic theories with modern exploration techniques, and to combine exploration techniques with GIS. During the performance of National Mineral Resource Assessment Project, geologists use “Deposit Synthetic Information Modeling Volume Method” to estimate the potential resource. The main principle of this method is to estimate the potential resource of the predicted areas by the ore bearing coefficient of the model area. The authors choose Hongshishan nickel deposit as model to show in detail how to delineate the area and depth of ore-bearing formations. Compared with those quantitative models now used in both domestic and abroad, the method discussed in this paper takes genesis into account by identifying “ore-bearing formation”, which can improve the confidence level of quantitative assessment results.

Key words: mineral resources, quantitative assessment, prognosis model, ore-bearing formation, Hongshishan nickel deposit
