Carbonate-hosted sedimentary exhalative iron (+Mn)-barite-sulfide deposit.
Open pit mine, located some 15 km north-east of Sofia at an altitude of about 400m on the southern slopes of Stara Planina Mountain at the border with Sofia valley.
The deposit has been exploited for more than 50 years mining iron ore and barite.
Since 2009, an Indian steel tycoon is the owner of the mine, and for private collectors, it is very hard to get an entry permit.
