The analysis results of the geophysical, seismic tomography and mineragenic data are presented, revealing the prerequisites for the regular of the location large and unique precious metals and uranium ore nodes of Southeast Russia, East Mongolia and Northern China. Shown that probable causes localization of the world-class ore clusters and districts above a stagnant oceanic slab perimeter are predetermined by concentration of the lower mantle fluid-heat fluxes at the frontal part of the slab and on its flanks, which are represented by sublatitudinal paleotransformal faults.
