Johannesburg - A third body was on Monday morning brought to the surface at Harmony Gold's Kusasalethu Mine, near Carletonville in Gauteng.

The dead man was one of the five mineworkers who trapped underground since Friday morning after a rockfall. 

The 1.8 magnitude seismic event, about 3,100 metres below the surface, occurred at around 10.30am causing a 10-metre fall of ground. 

Specially trained mine rescue teams brought the first body to the surface on Saturday. Another body was retrieved on Sunday. Two miners remain unaccounted for.

Harmony Gold said search and rescue efforts will continue to recover the remaining two trapped employees.
"Our sincerest condolences go to the family and friends of the deceased. We will not rest until the other two employees have been found and brought to surface," Harmony Gold chief executive, Peter Steenkamp, said.

Trade unions have questioned the safety measures at the mine and are mulling a review of the legislation.
