One of the two men trapped in a mine in Germiston has been declared dead by emergency services after he was brought to the surface of the mine around 18h00.
Both men were trapped after descending into the mine on Stanley road in Primrose before 15h00 this afternoon.
Fire and rescue workers have had great difficulty in bringing both men to safety and will now bring the second man to the surface of the mine as soon as possible.
It is believed that the owner and one employee of the mine had descended more than 75 meters into the mine to check on water levels.
ER24 paramedics were called to the scene at 15h00 and arrived to find one of the men had run out of oxygen at that time.
Local authorities are conducting an investigation.
