Methodological bases of mineral resource potential assessment: international and Russian experience

Тhe paper considers the main approaches to the valuation of mineral deposits. The valuation of mineral resources is widely used in countries with developed mining industry, such as the USA, Canada, Australia, etc. Monitoring the value of mineral assets allows you to track cur-rent changes in their structure and serves as a basis for the fair withdrawal of mining rent. The methods of financial and economic evaluation of mineral deposits are based on the standard methodology for investment projects assessment. The most widely used is the net pre-sent value method, which is used only for the estimation of commercial reserves. The resource assessment can be carried out using comparative methods and be used to improve the informativeness of the assessment. The paper reviews the methods used to access the mineral resource potential of Russian regions, forms of statistical observation, and standards of the Russian Society of Appraisers. Contemporary Russian legislation in the field of mineral raw material valuation is based on international experience, where the main valuation method of mineral assets is the method of net present value. With the approval in 2017 of the statistical form "Information on the current market value of mineral reserves”, official annual data on the value of mineral raw materials in the subsurface appeared in Russia for the first time. The methodology for assessing the mineral resource potential of the region should include such stages as ranking mineral deposits according to their investment attractiveness, evaluating selected deposits with approved re-serves using the net present value method with determining the budget efficiency of projects, and evaluating the gross potential value of re-sources of promising mineral resource objects.
