Modern methods of nanomineralogy (electron microscopy, electron probe microanalysis) were used to study the ores of one of the largest industrial facilities of the Republic of Uzbekistan –the Zarmitan gold zone, including the Zarmitan, Urtalik, Guzhumsay deposits, which are located in the Koshrabad granosyenite massif. The development of / Au-W / Au-Bi-Te / Au-As /Au-Ag-Te / Au-Ag-Se / Au-Sb-Ag / Au-Hg / types of ores. Productive mineral-geochemical types of ores are Au-Bi-Te gold-bismuth-telluride, represented by maldonite, tellurides and sulfosalts of bismuth: hedleyite, joseite, tsumite, tetradymite, matildite, treasure, and also Au-Sb-Ag goldsilver-sulfoantimonide type represented by aurostibite, sulfoantimonides Pb, Fe, Ag: plagionite,jamsonite, boulangerite, goodmundite, ovikhiite and gold-pyrite-arsenopyrite with nanogold,lellingite, gersdorfite. The main industrial resource of gold is provided by Au-Bi-Te, Au-Sb-Ag and partially Au-As types. The objects of the Zarmitan zone belong to the orogenic type of gold
deposits associated with the intrusion. The established mineral and geochemical features of ores are direct signs of prospecting, typification and assessment of hidden gold mineralization of orogenic belts.
