Key words: assessment of areas, the license, the mathematical model.
Possible methodological approaches for the prediction of the geological attributes of subsoil development projects that include the geological study stage are considered. Several methods of mathematical statistics were used: correlation and regression analysis, the approximation with help of curves. The results of the work include: mathematical models to predict the final increase in known reserves in the subsoil; the models for the prediction of the number of discoveries; and the distribution of shares of stocks discoveries through the ranks. Areas are numerically described whit help of characteristics, which are based on the data published by Government agencies at the Announcement of tenders and auctions for subsoil use. In order to construct the models real information about the exploration of the subsoil of the Perm Territory since 1978 were used. The constructed models and dependencies can be used to assess the subsoil in order to determine the prospects of setting exploration and acquisition of licenses. Analysis of the characteristics that included in the model allowed making conclusions about the impact of the characteristics of certain groups on the final results of the work on the areas.
