The attack, believed to be linked to the ongoing Association of Mineworkers and Construction Union (AMCU) strike, took place on Wednesday, Brigadier Thulane Ngubane said.
The 38-year-old man, an Anglo American Platinum rock drill operator at Siphumele 1 shaft in Rustenburg, went to work, although he was allegedly warned not to do so.
“It is alleged that four unknown men arrived at the shack where the victims were sleeping,” Ngubane said.
Both were treated for injuries by paramedics after the attack.
The extent of the couple’s injuries could not be confirmed.
“This incident once again proves that workers are being intimidated and become victims of crime if they go to work,” said Ngubane.
Amcu members in the platinum mining sector have been on strike since January 23 in demand for a R12,500 minimum salary a month.
The mining companies Lonmin Platinum, Anglo American Platinum (Amplats), and Impala Platinum (Implats) have offered staggered increases of seven to nine percent over the next tree years.
