Pressure mounts for Rio board after Australian cave blast review

Australian superannuation fund Hesta has become the latest investor to voice dissatisfaction over the findings of Rio Tinto’s board-led review into how the iron ore miner legally detonated historically significant Aboriginal rockshelters.

The comments come as Rio Tinto is expected to update investors within 24 hours on further steps that may bring more sanctions for executives, a separate Australian-based investor group told Reuters on condition of anonymity, on Thursday.
