On the gold content in the antimony and mercury mineralization in Priamurye

Abstract

The data on the geological and structural position, composition of metasomatites, ores, and gold content of antimony and mercury deposits and occurrences of the Priamursky gold-bearing area are presented. It was established that the ores of many of them contain native gold, whose concentration reaches commercial values. Some of the gold-bearing antimony and mercury deposits serve as sources of the formation of gold placers. By the composition of ores, near-ore metasomatites and samples of native gold, the analogues of these deposits and occurrences are the famous gold deposits of Yakutia - Sarylakh of the gold-antimony formation and Kyuchus of the gold-mercury formation. It is recommended to audit a number of mercury and antimony deposits and occurrences in the Priamursky province for gold. As a result, it is expected to identify deposits of gold-antimony and gold-and-mercury formation. In addition, occurrences of antimony and mercury may be indicative of the presence of gold-sulfide formation deposits in the bedrock, similar to a large deposit Mayskoye (Chukotka).
