Expelled ANC Youth League president Julius Malema will speak out on Tuesday after he was denied entry to an event where North West miners were to be briefed.
"The press conference will make concrete reflections on the political developments in South Africa," Economic Freedom Fighters spokesman Floyd Shivambu said in a statement.
"The press conference will also speak to the physical prevention of Malema from addressing mineworkers in Marikana despite the plea that he should come address them."
Shivambu said the briefing would also deal with the involvement of the "economic freedom fighters" in "struggles facing mineworkers and soldiers".
On Monday, police stopped Malema at the gates of Wonderkop stadium, where the workers had gathered to be briefed on developments about their wage demands.
After a lengthy discussion, Malema drove off, escorted by about 10 police vans.
It was not immediately clear whether Malema would be able to visit the family of people who were injured by rubber bullets on Saturday, or if he would leave the area.
A police helicopter circled above, while police on foot patrol ran to points of entry to stop Malema if he made any turns.
