London, May 1, 2019 (AltAfrica)-All 1,800 workers who had been trapped at a Sibanye Gold Ltd. underground platinum mine in South Africa have been brought to the surface, the Department of Mineral Resources said in a tweet.

Sibanye Stillwater spokesperson James Wellsted revealed that supporting rails had fallen down a shaft, preventing workers from exiting.

“At about 13:00 today [Tuesday], some rails which were being transported underground at the Thembelani shaft, Rustenburg, whilst being slung under the conveyance, came loose and fell down the shaft,” read a Sibanye Stillwater statement.

No one was hurt in the initial accident or the rescue attempt.

The incident revives concerns about safety at Sibanye, which last year suffered a spike in fatal accidents at its gold mines.

About 1,000 workers were also trapped underground for more than a day at one of the producer’s operations in February 2018 after a storm damaged power supplies in the area.

South Africa, the world’s biggest platinum producer, has the deepest mines in the world. (Ctgn)
