"The CEOs will not be in Rustenburg today. They are not part of the mass meeting. It is an Amcu meeting," spokesperson for platinum producers Charmane Russell said.
"The companies will get formal feedback from Amcu after the meeting."
Some of the workers at the Royal Bafokeng Sports Palace in Phokeng, near Rustenburg, appeared to believe Amcu leader Joseph Mathunjwa would sign the wage settlement with the CEOs of Impala Platinum (Implats) [JSE:IMP], Anglo Platinum [JSE:AMS] and Lonmin [JSE:LON] later on Monday to end the protracted strike.
"We expect CEOs to be here. The agreement will be signed here at the stadium," Amcu branch leader Abram Ramasedi said.
Amcu members sang struggle songs as they filed into the stadium on Monday morning. A tent had been erected at the venue, ostensibly for the signing.
Amcu members in green T-shirts were bussed in from various shafts, including Amplats' operations in Limpopo.
Amcu members have been on strike since January 23 demanding a basic monthly salary of R12 500.
