Evaluation Methodology for Pre-Mining Potentiaity for Mineral Deposits

Abstract

Here we introduce "Pre-mining potentiality of mineral deposit" and gets marked "P_pm" under this methodology, which comprehensively represents the mining and geological conditions in the crust, the geologic parameters, study and calculation of mineral reserves, mining method, moreover assessments of other studies such as for operation, location and marketing capabilities, a warning forecast of the economic viability and environmental impact on nature. The pre-mining potentiality evaluation of mineral deposits can be considered as the most comprehensive pre-production assessment of a deposit, which makes it possible to compare it with other same type deposits and to assess and determine the priorities of this field. External factors, the method of mining development, production productivity, the technique and technology of the extraction system, the amount of capital investment, the professionalism and the capacity of management and financial capacity of the project executor, show the main effects on the actual magnitude of the final social and economic benefits that result from the overall implementation of the project. And the internal factors in it, deposits, mining and production and economic as well as environmental conditions, are the main foundation for those external factors. These internal factors need to be examined before operational phase or during mine development, with detailed study in the framework of consistent scientific research and consider clearly the logical and expected results of future mining operations. The following research works are carried out to develop a mineral deposit. Including: reconnaissance studies, geophysics, hydrogeology, geotechnical studies, resource delineation, evaluation work - a scoping study, preliminary and detailed feasibility studies, detailed environmental impact assessment. In international practice these research and evaluation works are called in general in Russian “предэксплуатационные исследования месторождения полезного ископаемого” and in English “pre-production evaluation for mineral deposit”. These works of research and analysis for the development of a deposit are not feasible simultaneously for all similar deposits, which require a lot of time and cost, therefore, the possibilities of evaluation and comparison are not obtained, and their priorities are not well determined. So, here a scientifically methodological question is being considered to evaluate the pre-mining potentiality, which is based on the influences of the internal factors of a given deposit, regardless of time and cost, for evaluation, comparing and ranking in general.
