Four mine workers died at Tau Lekoa gold mine in Orkney, North West province of South Africa, as the result of a seismic incident in the town. The miners were trapped underground at a shaft when the incident happened on 22 July and rescuers have since recovered the bodies. Mineral Resources Minister, Mosebenzi Zwane, says the death of four mine workers at the mine in is unacceptable and  has called on mining companies to do more to make mines safer for workers. The Congress of SA Trade Unions (COSATU) was quoted by African News Agency as saying: "COSATU and National Union of Mineworkers (NUM) leadership have been observing efforts by the rescue team to recover bodies." Responding to the incident, the National Union of Mineworkers health and safety secretary Erick Gcilitshana said: "This accident, like any other mining accidents, could have been prevented. We are told that recommendations were presented by rock engineers to the mine on how to mine safely".
