    Question

    Hudbay and Mitsubishi sanction Copper World mine construction for 2029 output

    Direct answer

    Hudbay Minerals and partner Mitsubishi Corporation have finalized the internal approval to begin full construction on the Copper World mine project in the United States. The asset is designed to serve as a primary domestic source of refined copper starting in 2029. The multi-year lead time highlights ongoing structural constraints in bringing greenfield copper supply online, even as demand from grid electrification and industrial applications compounds over the medium term.
