Results of field studies run on Zakharovskoie polymetallic deposit (Altaiski Krai) in order to investigate structure of superimposed haloes and to determine velocity of migration of elements forming haloes, are discussed.

The method of partial extraction of metals is applied in the search for deep deposits in two variants: extraction under the action of an active electric field (PEM) and diffusive extraction of metals under the action of electrochemical potentials (PEM-MDI).
