Derelict and Ownerless Mines Project

The renewed contract for the Derelict and Ownerless (D&O) mines project

The renewed contract for the Derelict and Ownerless (D&O) mines project commenced on April 01, 2015, and will continue until the 2017/18 financial year. The D&O project is funded by the Department of Mineral Resources (DMR). Generally the scope of the project entails the D&O mine database management and maintenance; Specialist studies on the D&O mines and closure of dangerous mine openings. Furthermore, the D&O specialist studies include environmental, geochemical, geohydrological, hydrological, geotechnical, and dust and air quality studies.

On the other hand, we also undertook the post-closure rehabilitation monitoring and maintenance and phytoremediation studies. Figure 1.2 below shows the locations of about 6000 D&O mines in South Africa. The CGS project team is continuously carrying out both desktop- and field investigations on the D&O mines in Limpopo, Gauteng, Mpumalanga, North West, Free State, KwaZulu-Natal, Eastern Cape, Northern Cape and the Western Cape provinces. The field investigations are aimed at collecting information about the D&O mines followed by the process of prioritizing these mines for rehabilitation using the criteria of risk ranking. Thereafter, the decision to rehabilitate the mines will generally depend on their negative impacts on people and the environment.
