The antimony-arsenic-thallium-gold mineralization occurs within a zone almost 3 km long and 200 – 300 m wide. Sb and gold dominate the central part of the deposit, but it also contains significant amounts of arsenic, thallium, minor barium, mercury and traces of lead. The ore bodies contain 2 to 3% antimony, 2% arsenic, up to 0.4% thallium, up to 3.5 ppm gold and 435 ppm barium. In this paper geochemical and mineralogical characteristics of the central part of the Alšar deposit are presented along with the results of new investigations of some specimens from this area. ER -
