One of the priorities of Russia's transition to post-industrial development is the upgrade of mineral resources sector as a major system-building industry which includes exploration, extraction, refining, transportation and processing of minerals. The main directions of modernization in the subsoil resources management are improvement of methods and technologies under exploration, automation and computerization of work and equipment at the stages of production and transportation of mineral resources, improvement of equipment and technology with the use of nanotechnology in the stages of enrichment and processing of mineral raw materials. Actual direction of modernization in the ore mining industry today is creation and improvement of techniques and technologies to work in the northern climate according to the Program of subsoil resources development of the North and the Arctic shelf. Due to the exhaustion of large raw mineral deposits and geological complexity of the conditions of mining, there is a need for new types of mining and extraction equipment in the industry and development of processes to extract minerals from the non-traditional raw materials.

In article the authors suggest to apply a system-synergetic approach to a complex assessment of mineral resources within methodology of spatial subsurface use. This approach will allow considering the factors arising in modern world economic space under the influence of processes of internationalization, integration and globalization. Authors give methodical tools of a complex assessment of mineral resources taking into account social, ecological and spatial factors in the conditions of uncertainty. Such estimate is expedient to carry out at all stages of prospecting works, including the earliest stages. At finishing stages of prospecting works, it is necessary to carry out an assessment of efficiency of the investment project on development of mineral resources, including estimates of the budgetary efficiency and efficiency of participation in the project of the enterprises and shareholders.
