'Testimony of Mr X is not credible’
Evidence leader Geoff Budlender believes Mr X fabricated certain parts of his evidence.
The miner, who turned police witness, is continuing his testimony from an undisclosed location for his own safety.
Mr X is standing trial on screen via a video link.
He claims that the miners planned to provoke and attack police officers during the violent strike in August 2012.
The strike left 44 people dead.
Evidence leader Geoff Budlender says Mr X has fabricated certain parts of his evidence and it's difficult to determine what is truthful.
Mr X has been unable to identify himself in certain photographs taken from the scene where two police officers and three miners were killed.
Budlender says there are inconsistencies in Mr X's two statements and it can't be determined if Mr X was at certain events or if he was told about them.
Mr X has blamed all the violence and deaths at Marikana on Association of Mineworkers and Construction Union President Joseph Mathunjwa who he says was just there to gain members for his union.
Mr X maintains that the miners took muti, believing they'd be protected from the police's bullets and planned to attack them shortly before the officers opened fire with live ammunition.
