Significance

It is a normal character of the mining business that the coal reserves will be finally depleted in every mining operation. The Company therefore places an emphasis upon the need to prepare for mine closure from the beginning and carries on throughout the mining life. This ensures that all areas are returned to a native ecosystem with the acceptance of related stakeholders.

Management Approach
The Company’s mine closure standard is developed in line with the International Council on Mining & Metals (ICMM) guideline and applied across business units. With an aim to minimize the environmental impact, the standard encompasses several measures such as land stabilization, waste management, water management, and mine rehabilitation. For each site, the environmental impact assessment is performed, and the mine closure plans are developed. The Company also monitors progress with reference to the mine closure plan. For open-pit mining in Indonesia, the progress of revegetation is monitored. While in Australia, the progress of mine closure activities is monitored.
