History
In January 1939, the Bulgarian-Swiss society Granatoid and the German companies Scholberg Zinc, Otto Wolf and Felten and Guillaume founded the Pirin Joint-Stock Company [2] to develop lead-zinc polymetallic ores in the eastern Rhodopes . Work began on the construction of mines and infrastructure. After the Second World War, according to the terms of the peace treaty, the USSR acquired the assets of German capital in Pirin JSC, so GORUBSO - Mining Bulgarian-Soviet society was formed. In October 1955, the Soviet side transferred its part of the property to Bulgaria’s Mountain Council.
