THE National Union of Mineworkers on Monday called on the government to suspend the liquidators of East Rand Proprietary Mines and launch a full investigation into their activities, according to the Business Report. ERPM was placed in liquidation in July this year. Last week it was sold to a black-owned mining company, Khumo Bathong. NUM alleges that the liquidators have started stripping the assets of the mine and selling them off piecemeal. It also alleges the liquidators tried to prevent Khumo from buying the mine, the paper reports.
