Commercial exploitation of the Antimony veins dates at least fromĀ 1840 and possibly before. Demand was traditionally driven by war conditions. By the end of the Russo-Japanese war in 1907 the mines were closed. These were reopened in the 1930s and ran until lateĀ that decade. In 1932, the mines produced around 1,000 tonnes of concentrate.
The deposit was remarkably free of Arsenic, unlike Cucma. Production continued sporadically continued during the Nationalsozialist, period. The Germans were successful at identifying Tungsten withinĀ the mineralisation. (some samples grading 2.4% WO2)Ā
Work was done in the 1950s to reopen the adits and firm upĀ resources, but larger mines such as Cucma and Dubrava tookĀ priority. Gold is present at the site (with records of 58 g/t) and recentĀ sampling has yielded Silver grading up to 237g/t. There is a recentĀ Lidar survey of the concessions.
