Lonmin miners strike in South Africa, unnerving investors

MARIKANA, South Africa (Reuters) - Thousands of miners remained on strike at two shafts in South Africa's Marikana platinum mine on Tuesday, operator Lonmin Plc said, revising an earlier statement that they had gone back to work.

The conflicting statements sent platinum prices, South Africa's rand and Lonmin's shares on a bumpy ride, highlighting nerves over the health of the country's key mining sector after months of labour unrest.
