We offer the integrated method of geochemical exploration for a wide range of ore minerals. This technology is more effective for precious metals. It includes the present-day modification of lithogeochemical technique of residual and overlapping dispersion halo. The precision analytic (ICP-MS and other) are used. The data is processed by means of the multidimensional mathematical statistic algorithm. The results allow to locate low-contrast halos of deep and covered deposits.
