Kenyasi, August 7, 2012 – Newmont Ghana has confirmed that the cause of fish deaths in the Ahafo Water Storage Facility (WSF) in January was due to low oxygen levels in the water.

Randy Barnes, Regional Vice President, Environment and Social Responsibility, said, “the company’s earlier position as well as that of experts from the Water Research Institute indicated that the oxygen levels in the facility at that time of season were low and likely to have led to the death of the fish. We have since engaged a team of experts from the Fisheries Commission and Water Research Institute who are carrying out a comprehensive ecological study of the facility that would help us understand the seasonal nature of the fish deaths as well as the future management of the facility. This information regarding low oxygen levels in the water is based on results from external laboratories,” he added.

The Environmental Protection Agency has also conducted its own investigations and is expected to make its findings available to the public.

Newmont’s  ongoing  routine  water  monitoring  continues  to  verify  that  the  water  in  the  WSF  is  in compliance with EPA standards. We also continue to monitor the water quality of boreholes that we have provided for the communities around the facility and they remain safe for human consumption.

The WSF is a fresh water dam that is within the boundaries of the mine and was built to provide water for the mining operations. It is a restricted area and has a community patrol team to educate the public about the WSF and to prevent potential trespassers from fishing or swimming in the facility. We remain committed to the safety and well-being of our host communities and will continue to work to the highest standards in safety and environmental stewardship.
