The necessity of developing main strategies for effective mining of secondary industrial placers is substantiated based on the analysis of results of precious metal natural placers development in the FEFD with the objective of reducing the economic and social tension in the traditional regions of alluvial mining and improving the ecology in the region. When analysing the genetic characteristics of industrial placer formation in different regions of the FEFD, the characteristic feature of natural placers directly affecting the qualitative characteristics of man-made mineral formations should be considered, i.e. distribution of reserves in the most natural placers, both in content and in geometry, changes by a certain regularity - by the cluster type. Other features of industrial placers are reflected which characterize their high resource potential as well as the need for major scientific and practical research methods to assess resources and reserves of industrial placers, create high-payoff technologies for their development and beneficiation, to generate databases of man-made mineral targets and the unified system of keeping records and monitoring, and to develop special-purpose technologies. Main directions of strategy development to mine secondary industrial gold placers also include the need to address legal issues relating to their status.
