South African police barred firebrand Julius Malema from a rally of striking miners Monday, as President Jacob Zuma warned that the country could ill-afford a recession over mine stoppages.
Zuma told a conference of the country's powerful Cosatu labour group that 4.5 billion rand ($548 million, 417 million euros) had been lost in gold and platinum production this year and a further 118 million rand in the coal sector.
"The impact goes beyond the mining sector," he cautioned, saying the manufacturing sector was showing strain.
"We cannot afford to go into a recession, and revert to the 2008 and 2009 period where the country lost close to a million jobs, which we are still battling to recover."
The warning came as British mining group Lonmin cut its platinum sales forecasts over the ongoing strike at its Marikana mine which has been blighted by a violent strike that has crippled production for more than a month.
Lonmin became the epicentre of a wave of unrest to hit the vital mining sector in recent weeks, with tensions forcing several firms to suspend operations in the country's platinum belt of northwestern Rustenburg.
The striking miners at the Marikana mine meanwhile have accepted for the first time to lower their monthly slalary demand of 12,500 rands (1,160 euros, 1,520 dollars), the mediator in the dispute said Monday.
Bishop Jo Seoka, president of the South African Council of Churches, told the SAPA news agency that he could not disclose the figure before they tabled it at negotiations with Lonmin set to resume Monday.
The miners were reportedly prepared to accept a monthly salary of 11,000 rands, according to news channel eNCA. The strikers claim they currently earn about 4,000 rand per month.
The government on Friday announced that it will no longer tolerate the unrest and ordered security forces to clampdown on illegal gatherings, weapons, threats and incitement which have characterised the spreading troubles.
Police at the weekend swooped on Marikana with the support of the army, seizing traditional weapons from workers and using rubber bullets and stun grenades to disperse workers gathering without police clearance.
Early on Monday police arrested 42 people for embarking on an illegal strike a shaft belonging to Royal Bafokeng Platinum.
The rabble-rousing Malema on Monday was also targeted by the crackdown after he was physically turned back by armed police, who gave him 10 minutes to leave, as he was about to enter a stadium where workers had gathered in Marikana.
The former youth leader was axed from Zuma's ruling ANC party but has grabbed the spotlight of South Africa's mining unrest by using the events to fire up worker frustrations and lobby for wildcat stoppages.
Following a semblance of stability after the crackdown -- the boldest since police gunned down 34 Lonmin protesters -- the world's fourth platinum producer Aquarius Platinum and a top chrome miner XStrata reopened two mines Monday.
The world's top producer Anglo-American Platinum, which last week pulled down shutters on five mines in the platinum belt, said it will re-open on Tuesday.
Zuma urged striking mine workers and employers to find a solution to a spike in labour troubles that has flared into bloodshed and led to mine closures.
South Africa's Treasury had forecast an indirect loss of 3.1 billion rand from the national revenues from strikes and stoppages on mines, said Zuma.
Meantime the London-listed Lonmin, the world's third-largest platinum producer announced Monday it expected annual sales of between 685,000-700,000 ounces of platinum. That compared with its previous prediction of 750,000 ounces.
Acting chief executive Simon Scott warned that the strike could spark more job losses at the mine, as the firm cancelled its contract for 1,200 jobs. Lonmin had warned a protracted strike threatened some 40,000 jobs in South Africa.
