Constant exploratory standards are defined at the exploration completion stage for the calculation of all reserves of the deposit on the basis of geological, mining-engineering and ecological substantiation. There is excluded the economic substantiation of the standards for a specific deposit at the given stage. Those standards` parameters, which are defined by technical-economic calculation, should be normative. Standard indices are set for each mineral resource and ore type on the basis of development experience of analogous deposits, peculiarities of deposits` geological structure of this type and processing indices. In the process of substantiation of the constant exploratory standards, it is necessary to set the scales and worth of a deposit. Meanwhile, the deposit’s worth should determine its position in the range of the similar explored deposits and deposits, which are being developed. On the basis of this, the question of the deposit’s industrial significance is decided.

Constant operational standards should be substantiated in the engineering design of a deposit`s development, including the development of the technology of mineral resources` mining and processing. The standards’ parameters are calculated on the basis of the designed indices and computations, including the economic. On the basis of the operational standards there are calculated and stated the reserves, liable to mining within this project`s range of action. At the same stage, the completeness of the mineral resource extraction is substantiated and the reserves are divided into balanced and trans-balanced.
