IMPROVEMENT OF ECONOMIC ASSESSMENT METHODOLOGY OF THE GRAPHITE AND APATITE DEPOSITS AVAILABILITY IN THE AREAS OF NEW DEVELOPMENT
The relevance of improving the methodology of economic assessment of the availability of deposits reserves is due to the need to use the expert-analytical method in the calculations, which is based on the data of geological mapping and forecast studies, the geography of the location of mineral deposits and the economic characteristics of the forecast resources of the territory and reserves of deposits. The object of the study is the mineral resource base of reserves and forecast resources of graphite and apatite deposits on the territory of the Republic of Sakha (Yakutia). The subject of the study is the improvement of the methodology of economic assessment of the cost of geological exploration works. The purpose of this study is to improve the methodological support of geoinfor-mation modeling of the availability of deposits reserves for the subsequent transfer of the forecast potential of minerals to the proven reserves for deposits in the areas of new development of the Republic of Sakha (Yakutia). To achieve this goal, it was necessary to solve the following tasks: to determine the methodological justification of geological and economic zoning; to form the principles of geological and economic modeling. The scientific novelty of the study is that the author improved the methodology for economic assessment of the availability of graphite and apatite deposits in the areas of new development. The practical significance lies in the possibility of using the results of the study to assess the mineral resource potential of field reserves and forecast resources in the areas of new development.

Highlights:
♦ when forming a methodology for the economic assessment of the availability of reserves of deposits, it is necessary to proceed from the structure of a standard request for providing information about a subsurface area. One of the main principles in the formation of the methodology is the stage-by-stage conduct of geological prospecting work;
♦ improvement of the methodology for economic assessment of the availability of graphite and apatite deposits in the areas of new development consists in the introduction of the following geological and economic indicators into the methodology for calculating reserves: the geo-economic potential of explored reserves; the geo-economic potential of geological reserves; the geo-eco-nomic potential of forecast resources, the calculation of which takes into account the features of the geological structure and heterogeneity of deposits in the areas of new development, as well as the insufficient infrastructure availability of these fields;
♦ the database of geological and economic indicators accumulated over a certain period within the framework of the State Cadastre of Deposits will automatically prepare data and generate reports at the request of federal and other authorities and organizations on the state of the mineral resource base and subsurface use at the state level in order to increase the investment attractiveness of subsurface use facilities.
