All 1,800 workers trapped underground at a platinum mine in South Africa have been brought to surface, the government's Department of Mineral Resources has said in a tweet. Rails had fallen down a shaft on Tuesday afternoon, leaving the workers "stuck" underground at the mine in Rustenburg in North West province, the mine's owner, Sibanye-Stillwater, said. Last year, 955 miners were rescued from a Sibanye-owned gold mine after a storm damaged electricity supply and trapped them underground. The firm had a "dismal" track record at its gold mines during 2018, when 21 employees were killed in the first half of the year, prompting a much tougher stance on safety, South Africa's leading financial publication, Business Day, reported.
