JOHANNESBURG - Mineral Resources Minister Gwede Mantashe has lambasted mining companies.
This after the deaths of four mine workers at Sibanye-Stillwater's Kloof mine near Westonaria.
The search for a fifth miner continues.
Mantashe says the biggest challenge for the mining industry is stemming the deaths in the sector.
"My own observation is that there is a big challenge for us to stop the riff from becoming a killing field," he said.
Meanwhile, the Bench Marks Foundation says the number of deaths at Sibanye-Stillwater's operations suggests the company's putting profit ahead of worker safety.
Unions Amcu and NUM are calling for serious intervention at Sibanye-Stillwater.
