All eyes will be on Rio Tinto Ltd (ASX: RIO) shares tomorrow for a couple of reasons.
One is that the mining giant is scheduled to release its quarterly update before the market open.
The other reason is that after the market close today, it announced the appointment of its new chief executive.

This afternoon, the miner revealed that its board has appointed Simon Trott to succeed Jakob Stausholm as chief executive. This will be effective from 25 August 2025.
