Copper World will begin mining in Southern Arizona in 2029

Hudbay Minerals Inc. and Mitsubishi Corp. will develop the Copper World mine in Southern Arizona, starting construction this year and mining from 2029. The project, expected to create jobs and generate $1.1B in taxes, faces environmental opposition. Mitsubishi will invest $423M for a 30% stake. The mine aims to produce 102,000 metric tons of copper annually, with 390M metric tons of reserves. Hudbay shifted focus to private land after legal challenges to its Rosemont Mine plan.
