Independent consultant Dr Paul Jourdan on Thursday urged South Africa to cease sending people down dangerous deep-level mines and to come up with remote machinery to mine at depth. He was speaking at the Southern African Mining Supply Chain Conference and Strategy Workshop , which was hosted by the South African Institute of Mining and Metallurgy and the Mandela Mining Precinct, in partnership with mining supply chain clusters, alongside the Local Southern African Manufacturing Expo at Nasrec’s Johannesburg Expo Centre.
