Economy.
In the early 20th-century, the mountains were noted as having large amounts of lead. A mine active in the region since 1825 was Bulgar Maden. As of 1920 it was still producing lead as a Turkish government ran enterprise. The ore from this mine was 44.2 percent lead. Silver and gold were occasionally found in the mines. The mine used a low quality smelting technique, which often threatened the quality of the product, leaving much of it lost. The gold and silver findings were sent to Istanbul for smelting.
Fauna.
Montivipera bulgardaghica is a venomous viper species endemic originated from this mountain range.
