Low rates of investment in the global mining sector have put the global energy transition at risk, widening the supply gap in critical minerals like copper, Rio Tinto chairman Dominic Barton said on Monday. "The gap is humungous, and I am actually very worried about whether we will be able to close (it)," Barton said via video link at the Ecosperity conference in Singapore.
