what happened
Japan's Mitsubishi Corporation has signed off on developing the Copper World copper project alongside Hudbay. It expects to contribute an additional $423M in equity, which would bring its cumulative investment in the project to $1.02B.
Production is scheduled to start in the second half of 2029, with an average output of about 100,000 tonnes of copper a year over the mine's life. According to TradingView, citing a press release from Mitsubishi distributed by Japan Corporate News, all major permits have already been secured. The company is also considering a cathode leach facility that would produce copper cathodes.
why it matters
The decision moves the project from early-stage commitment into full investment, with defined capital spending and timelines. For the copper market, it points to a sizeable new supply source closer to the end of the decade. Key milestones to watch are the final financing structure, construction progress and the decision on the leach facility.
