Gold One Mine says they will be on standby with water and medical supply should the mine workers spend more time underground.
Over 400 mine workers have staged a sit-in at the mine's Modder East Operations in Springs, on Gauteng's East Rand.
This is the second sit-in following a similar one in October where 500 workers only resurfaced after 3 days.
