Abstract Our article discusses the materials obtained by the authors in the study of the oxidation zone and primary ores of various deposits of the Kokpatassky ore field. The obtained research results confirm that the predominant part of gold remains in minerals replacing sulfides (pyrite, arsenopyrite) with the preservation of gold and its characteristic satellites in the oxidation products of sulfides (hedrogoethite, goethite and scorodite). Native gold belongs to fine and small size classes. The main concentrators of native gold are quartz, carbonate and oxidized forms of sulfides. Often, together with gold, arsenopyrite, scorodite, tetrahedrite, acanthite, electrums are noted.
