[2] The mountains have granite intrusions that are associated with gold deposits, as well as iron ore, bauxite, magnesite and talc.

The range stretches along the right bank of the Yenisey in the southwestern edge of the plateau, between the valley of the Kan River in the south and the Stony Tunguska in the north, beyond which rises the Tunguska Plateau.

The highest point of the range is 1,104 metres (3,622 ft) high Yenashimsky Polkan, located in the upper course of small rivers Yenashimo and Chirimba.

The Angara River flows across the area of the range to join the Yenisey off its western slopes.

The tops of the higher peaks are bald with clumps of small shrubs and areas of scree.
