Gold occurs at Tokur in quartz veins cutting Palaeozoic slates and shales, within a thrust-sheet structure.  There is apparent secondary enrichment in the oxide zone.  Tokur has been mined exstensively underground to a depth of 400 m, and has produced 35 tonnes of gold.  The principal mineralisation at the old Tokur Mine was associated with a silicified zone along a major thrust fault, known as the Glavny Fault.
