We investigated podzolic soil, which is formed above the host rock of Novye Pesky gold ore occurrence. Mobile forms of Au, As, Cu, Ni, Zn, Se, Ag, Te, Sb, Pb, Mo and Bi were identified with a sequential extraction method and migration form calculation by Geochemist's Workbench in secondary dispersion halo. The gold has characteristics different from other elements: the main mobile forms of gold are water-soluble, bound to organic matter, bound to Fe and Mn-(oxy)hydroxides. The main forms of gold are AuCl2-and Au+ in the aqueous phase.
