The official report into the police killing of 34 South African miners in 2012 is due to be submitted to President Jacob Zuma today, with rights groups demanding that its findings are published immediately.
The shooting at Marikana was the worst violence witnessed in the country since the advent of democracy in 1994, and evidence at the inquiry tarnished police claims that they acted in self-defence when they gunned down the striking miners.
In the days before, 10 other people were killed in other violence around the platinum mine, including non-striking miners, security guards and two police officers who were hacked to death.
The Marikana Commission of Inquiry, headed by retired judge Ian Farlam, was established two years ago by Zuma to investigate the deaths.
"The surviving victims of the tragic events of Marikana and the families of all those who died have a right to receive justice."
Phuti Setati, secretary of the Marikana Commission, told AFP the report would be submitted to the President today, but that the commission had no influence over whether or when it would be published.
It has also been blamed for the murders of its security guards and non-striking miners. The mining house has denied any responsibility.
They also argued that Lonmin executives should be charged as accomplices.
Ramaphosa contacted the ministers of police and mineral resources in the days leading up to the massacre, pushing for police intervention over the strike.
Ramaphosa was not in government at the time, but a non-executive director of Lonmin and a senior leader in the ruling ANC party.
He has maintained he was simply trying to prevent further violence.
