Douglas Morrison, chief executive of the Centre for Excellence in Mining Innovation is pictured outside his office in Sudbury, Ontario October 16, 2012. Vale SA, the Brazilian-based company that owns the Copper Cliff mine near Sudbury, has spent nearly $50 million in the last two years to build a transport system known as "rail-veyor". The equipment, made locally by Rail-Veyor Technologies Global Inc, is one of an array of technologies being developed as miners look to a future where production is run almost entirely by people safely above ground.
