Johannesburg, Dec 4 (AP) The death toll from a mining tragedy last week in South Africa that involved an elevator has risen to 13 people after a worker died at a hospital, the mine operator said on Monday.

Impala Platinum said that the worker died on Sunday from injuries sustained when the elevator plummeted around 200 metres (650 feet) down the shaft of a platinum mine while carrying workers to the surface after their shift on November 27.

Impala Platinum and the South African government announced an investigation into what mine officials called a highly unusual tragedy.

The industrial elevator was carrying 86 workers to the surface when it suddenly dropped back down into the shaft, which is a kilometer (about a ½-mile) deep. The mine in the northern city of Rustenburg was the world's biggest platinum producer last year. South Africa is by far the world's biggest platinum-producing country.

Impala Platinum said it would hold a day of remembrance on Wednesday, when it would release the names of the workers who died. (AP)
