Summary：Rio Tinto Starts Commissioning, Sparking Hope for Shanghai Metals Market Growth **Introduction** RRio Tinto Starts Commissioning, Sparking Hope for Shanghai Metals Market Growth
**Introduction**
Rio Tinto’s recent decision to begin commissioning its new processing line at the Oyu Tolgoi complex has sent ripples through the global metals sector. Analysts say the move could ease tight supplies of copper and gold, commodities that have been under pressure as demand from China’s manufacturing hubs rebounds. The development arrives at a pivotal moment for the Shanghai metals market, where traders are watching for signs that upstream output can keep pace with recovering domestic consumption.
**Key Developments**
The commissioning phase, which started earlier this month, involves ramping up a 150,000‑tonne-per‑annum copper concentrator and associated gold recovery facilities. Rio Tinto officials reported that initial test runs have met design specifications, with ore grades averaging 0.8 % copper and 0.5 g/t gold. The company plans to reach full commercial production by the second quarter of 2026, adding roughly 120,000 tonnes of refined copper to the market each year. In parallel, Rio Tinto has signed a long‑term off‑take agreement with a Shanghai‑based trading house, guaranteeing a portion of the output will be directed to the city’s futures exchange for hedging and physical delivery.
**Industry Analysis**
Market participants note that Shanghai’s copper inventories have fallen to their lowest level in 18 months, prompting a premium of about $80 per tonne over LME prices. The additional volume from Oyu Tolgoi could trim that spread by 20‑30 % if logistics remain smooth. Analysts also point out that the new line’s lower carbon intensity—achieved through renewable‑powered grinding mills—aligns with China’s stricter emissions standards for imported
