The Association of Mineworkers and Construction Union - AMCU - says investigations into mining fatalities must be sped up, especially in incidents that resulted in multiple fatalities. This is as the Department of Mineral Resources revealed that investigation reports on the findings, recommendations and any remedial steps have not been finalized with regard to the accident that claimed 13 lives at Impala Platinum's Shaft 11 in Rustenburg in the North West in November last year. Eleven miners were killed at the scene and 75 injured. Two miners died later in hospital. Sentleeng Lehihi reports.
