The analysis of the mineral resource base state in nonferrous metallurgy, the impact of economic reforms in 90-s is presented and the need for the uneconomic ore deposits use is noted on the example Sadon ore area. It is shown that a real revival of the nonsubsided polymetal production is possible on the basis of the traditional technologies and new technologies combination of the underground, heap and mechanochemical leaching. It is determined that Sadon ore deposits fit leaching in terms of the geological and mineralogical conditions. By modeling the economic parameters, the economic efficiency of metal leaching at various mining stages is substantiated. The mining economy restoration trend by creating the products from leaching tails after the metals extraction is recommended, being non-alternative one for the former mining level restoration in the region.
