Photo by Hudbay Minerals
Name of the Project
Copper World Complex.
Location
Arizona, in the US.
Project Owner/s
A joint venture (JV) between base metals miner Hudbay Minerals (70%) and integrated business group Mitsubishi Corporation (30%).
Project Description
The openpit flotation operation’s 15-year base case targets 102 000 t/y of copper over its first decade. Milling capacity expands from 60 000 short tons a day to 90 000 short tons a day in Year 5, with concentrate leaching remaining optional.
The 37-year extension case requires federal permits by Year 10. Initial operations have major permits.
Potential Job Creation
More than 1 000 construction jobs, 500 permanent jobs and up to 3 000 indirect jobs are expected to be created.
Net Present Value/Internal Rate of Return
In the base case, at $5/lb copper and an 8% discount rate, the project has an after-tax net present value (NPV) of $1.241-billion and an internal rate of return (IRR) of 16.8%. In the extension case the project has an estimated NPV of $2.510-billion and an IRR of 18.8%. Both have a payback of 5.4 years.
Capital Expenditure
Initial growth capital is reported at $2.07-billion.
Planned Start/End Date
First production is targeted for the second half of 2029.
Latest Developments
On October 21, 2026, the JV approved construction following completion of the definitive and related prefeasibility studies.
Key Contracts, Suppliers and Consultants
