Mineral exploration has environmental and social impacts. As OTML has been operating in the region for 34 years it is acknowledged that its operations have contributed to sediment aggregation in the Ok Tedi and Fly River systems. This impact has been well documented and is part of ongoing monitoring, research and reporting programmes mandated in OTML’s License to Operate. In fact, the mine’s continued operation is dependent upon consent by the CMCA communities and the State.

The Company's success is measured on its economic performance, human resource development programmes, zero harm safety performance, and the management and mitigation of its environmental impacts.
