Hudbay and Mitsubishi Greenlight Major Copper Mine Project in Arizona
The Rosemont Mine, expected to begin production in late 2029, signifies a significant investment in U.S. copper production.

Hudbay Minerals and its partner Mitsubishi Corporation have officially approved the construction of the Rosemont Mine, a major copper project located in the Santa Rita Mountains of Arizona. Production at the mine is anticipated to commence in the latter half of 2029.
