Impala Platinum mine accident in South Africa kills 11. On 28 November 2023 an accident at a platinum mine in South Africa has killed 11 workers and injured 75, the mine's operator says. Impala Platinum chief executive Nico Muller described it as the "darkest day" in the company's history. The firm said the accident involved a winding rope connected to a cage-style lift which hoists people up and down the mine shaft. The lift started moving downwards unexpectedly, it added. South Africa has some of the world's deepest mines. It is a leading producer of platinum, gold and other raw materials. There have long been concerns about safety conditions on its mines, but the situation has improved since white-minority rule ended in 1994. The latest accident took place on Monday at a mine in Rustenburg, about 100km (60 miles) north-west of Johannesburg. The deaths bring to 55 the number of fatalities on South African mines this year. "This is a terrible blow to our ambition of ending 2023 with fewer fatalities than last year when there were 49 fatalities, the lowest on record, and the continuation of our journey towards zero harm," said Mzila Mthenjane, the chief executive of Minerals Council South Africa, the main representative of mining firms in the country. Mineral Resources Minister Gwede Mantashe has visited the mine. Reference De Simone, D. & Chothia, C. 2023. BBC News. Impala Platinum mine accident in South Africa kills 11.
