The problem of Acid Mine Drainage (AMD) related to gold mining is now largely the responsibility of government. The DMR allocates funds both to the Council for Geoscience and Mintek from its budget specifically to find practical and economically viable methods to deal with AMD. The purpose of the visit was to understand the practical measures that are in place and to form a view on whether the resources currently voted to deal with AMD are sufficient. CGS is involved in closing/rehabilitating ownerless and derelict gold mines in ways that stop the ingress of illegal miners into the old workings.
