Status

Brought in additional contractors to increase mining volumes.

Key maintenance projects

Upgrade of the mining equipment at the Raspadskaya and Alardinskaya mines

The project aim is to acquire powered support units due to the increased longwall length, replacing shearers and longwall conveyors.

Status
