Hudbay Minerals’ (TSX: HBM; NYSE: HBM) updated prefeasibility study for the first phase of its Copper World project in Arizona has improved its economics and extended the mine life compared with a June 2022 preliminary economic assessment. However, the study, released Friday, drew mixed reactions from experts, mainly due to increased operating costs and cautious permitting approaches.
The Copper World PFS highlights show a project with lower up-front capex, a streamlined flowsheet, flexible modular construction optionality, and higher early-year grades which are positives for the project.
