Analyzed is the order of recognizing and reflecting mineral reserves/resources geological exploration, evaluation and development costs established in the RF which are materially contributing to general expenses of mining enterprises. Systematized are the issues requiring further scientific investigations and methodical solution in the area of determination of the technique of accounting for prospecting, evaluation and development of mineral deposits. Based on the world experience a proposal has been put forth to refer these costs to intangible assets of mining production units. The methodical approaches for determination of value and booking of intangible assets data have been developed to be applied in economic activities of mining enterprises.
