Rustenberg - The National Union of Mineworkers (NUM) is reclaiming its members in Rustenburg, an official said on Thursday.

“Our recruitment is moving fairly (well). We have moved from three percent to 11 percent at Lonmin in Marikana,” Rustenburg regional secretary Sydwell Dolokwane said.

He was referring to the percentage of the company's workers that had joined the union.

The NUM was a majority union at Impala Platinum's processing plant and was standing at 34 percent at Anglo American Platinum's Bathopele mine.

He said most of the NUM members who had joined the Association of Mineworkers and Construction Union (Amcu) were willing to rejoin the NUM but feared for their lives.

The NUM lost its majority status in 2013 after mineworkers left to join Amcu.
