On September 14, Rio Tinto PLC fell 3.08% in pre-market trading, trading at $96.88/share, with turnover of $1.1125 million.

On the news front, Rio Tinto PLC recently disclosed Q1 iron ore shipments of just 70.7 million tonnes, down 9% year-over-year to a six-year low, missing analyst estimates of 72.3 million tonnes. The shortfall was primarily caused by six severe tropical cyclones in the Pilbara region. Meanwhile, a sharp plunge in international copper prices triggered broad-based selling across copper-related stocks, intensifying downward pressure on the mining sector.

Balance sheet concerns also weighed on sentiment. Following the completion of its Arcadium Lithium acquisition, Rio Tinto PLC's net debt climbed to $7.6 billion, while full-year capital expenditure guidance reached $11 billion — the highest level in over a decade. Separately, Morgan Stanley recently initiated coverage on the stock with an Underweight rating and a $90 price target, while RBC lowered its target price from 6,300 pence to 6,100 pence.

Within the Diversified Metals & Mining sector, peers also traded lower: BHP Billiton down 3.18%, Teck Resources down 3.16%, USA Rare Earth down 2.63%, and MP Materials down 1.01%.
