Rio Tinto board needs mining skills, geographical diversity - chairman

The board of directors of global miner Rio Tinto needs more mining and renewable energy experience and a more diverse geographical background, its chairman Dominic Barton said on Friday.

"I think there's a lot of changes that need to occur. On the board we need the mining experience," Barton said in a pre-recorded interview at the FT Mining Summit in London.

"I think that capabilities on the renewable energy side (are) going to be quite important to have," he added.
