TimesLive reports diamond giant De Beers plans to put hazardous waste - and up to 1,000 prisoners - into its disused property and diamond mines in the picturesque Namaqualand region (depicted), in the northwest of South Africa.
The company, which also had to settle a two-week strike over wages on Thursday, said the projects were just two of several potential business ideas for the disused old mine areas and that the Department of Minerals have asked for further public consultation and an impact study.
Last month De Beers concluded a deal with the state power utility Eskom to build a 150MW wind farm on a large stretch of coast north of Kleinzee, one of two towns that form part of the De Beers properties.
