Two per cent of shift workers at Lonmin Plc's South African operations turned up for work on Friday, the platinum miner said.
The world's third-largest platinum miner has been crippled by a four-week strike at its Marikana operations.
The company signed a "peace deal" with some of its unions on Thursday. However, that did not include militant breakaway union AMCU.
On 16 August, police shot 34 protesters dead in an event that shocked the world with its echoes of apartheid-era police brutality.
Workers who were released from detention, after prosecutors dropped murder charges against them for the deaths of their colleagues, said officers had gunned down surrendering strikers and boasted of the killings.
The strikes at London-listed Lonmin has raised the prospect of unrest spilling over into other mining sectors and has also become a battleground for rival political and labour factions.
