A group of 11 investors ramped up pressure on Rio Tinto's board before the removal of CEO Jean-Sebastien Jacques. : As the backlash over the destruction of the 46,000-year-old Juukan Gorge rock shelters sent the board into crisis meetings last week, the group of fund managers and asset owners wrote to Rio Tinto chair Simon Thompson and his fellow directors saying they had failed to outline how the miner could restore trust in the community. Jean-Sebastien Jacques has left after shareholders revolted over 'inadequate' penalties for the destruction of prized Indigenous heritage in the Juukan Gorge.
