Harmony Gold and Newcrest Mining have, for the first time, publicly accepted their Hidden Valley mine in Papua New Guinea has caused pollution problems in the Watut River.
This is a significant admission from the two mining companies, in the face of mounting community pressure, as they have only previously spoken about 'higher than expected sediment loads' in the river system.
The companies have also announced steps to seek a 'constructive resolution' of the pollution problem in consultation with local people and their MP Sam Basil.
