Mining globally has come under pressure to gear down following a period in which commodity prices plunged to historical lows. Add to that the fact that mines are now deeper and more dangerous, geology is more difficult to navigate and continuous improvement is no longer sufficient to survive. In times of threat there is a flipside that requires interrogation, as the
