“The executives and management of Harmony extend their sincerest condolences to the family, friends and colleagues of our deceased colleague.
"The company continues to strive towards its goal of zero loss of life and will ensure that the necessary support is provided to the family in dealing with this tragedy,” Harmony CEO Peter Steenkamp says.
