The National Union of Mineworkers (NUM) on Wednesday said it was “deeply concerned” that its members and contractors at the Koornfontein mine, in Mpumalanga, have not received their salaries since November 2018. According to NUM Highveld regional secretary Tshilidzi Mathavha, the business rescue practitioners (BRPs) for the mine had paid Optimum employees after selling a dragline machine to Glencore for R80-million, following which the union had been informed that the Optimum and Koornfontein operations were detached from one another.
