Transferring of our open pit mines to underground mine in Indonesia due to its increasing mining depth. Underground mining will occur between +40m and -700m (-700 and below are unexplored areas)
Zone 3 Mine is chosen for the first underground mining development due to its high level of exploration, completed open pit production and easier access to haul road.
Our mines total resources: abundant reserves with estimated production of 0.9Mt / Annum.
Coal Qualities: low sulfur, low ash, thermal coal with high calorific value.
Underground mining aims to:
- Maximize the utilization of deep coal resource which will maintain and promote economic development.
- Maintain sustainable coal production with the current open pit productions are close to end.
