Rio Tinto is investing in automated drill rigs and a USD 1.5 billion low-carbon aluminium smelter in Quebec, aiming to cut emissions and improve efficiency. The company also backs Arctial's plan to build Finland's first new smelter in 30 years, which could boost Europe's aluminium output by 20 percent. Despite these moves, analysts flag valuation concerns. Rio Tinto shares trade at about 7.7 percent above the consensus target, and some estimates suggest the stock is 51 percent above fair value. Investors will watch project timelines and demand for low-carbon aluminium as key factors.
