The relevance of this study is determined by lack of information of the behavior and accumulation of non-conventional metals (-oids), such as tellurium, bismuth, selenium (TBS-microelements), involved in modern industries, as well as the limited information about deposits, in which they are able to accumulate significant concentrations, including in association with native gold. Such objects are represented by some epithermal deposits. Russia's share in the total balance of these deposits accounts for a negligible number, although in some regions, such as the Arctic, Siberian and Far East, they have a significant role. The key task of this research is to investigate the material composition and conditions of gold and TBS-microelements formation in an exotic for the low sulfidation type «copper mineral association» of the Baranyevskoe Au-Ag epithermal deposit (Central Kamchatka). The objects of the research are ores and their host altered rocks in the form of core-, hand-and-chip-samples. Research methods.
