Residents of Munsieville, Krugersdorp, on Friday combed a koppie in search of zama zamas operating in the area.
They then searched a nearby mine shaft after removing barbed wire strewn on the ground around the entrance. Using cellphones as torches, they ventured about 200m into the shaft but turned back after finding no-one inside.
The angry mob had earlier in the day caught two alleged zama zamas, who were handed over to police. Two other alleged illegal miners managed to flee the crowd.
Abigail Kapa said though their protest gained momentum on Friday, they had been blocking roads from Wednesday in solidarity with neighbouring areas.
“These protests can be taken wrongly but we want justice for those girls and others who have been victims of zama zamas. We want to make sure they stay away from our areas for good.
