Less than one in 10 Lonmin miners turned up for work at its Marikana mine in South Africa on Tuesday, the lowest level since workers returned following violence that left 44 people dead.
The government is meeting company representatives and unions on Wednesday for peace talks aimed at getting the mines operating again after more than two weeks without production.
The London-listed company, which is losing a potential 2,500 ounces of platinum a day, said just 8% of its 28,000 workers showed up as unions continued their protests.
Striking rock-drill workers are said to have threatened bus drivers bringing workers to the site, which may account for the low turnout.
Last week up to 27% of workers reported to their posts, but this soon slipped and just 13% arrived on Monday.
Lonmin initially threatened to sack workers who continued to strike after 34 were killed by police, which has led to a public inquiry.
The deadline was extended due to the deaths but was eventually scrapped by the company.
Shares continue to fall, down 10p at 630p on Tuesday, and down 19% since before the violence started.
Platinum prices have risen more than 10% in two weeks and Lonmin said it will breach its banking covenants which could lead to a rights issue.
