Freeport-McMoRan Chief Executive Officer Kathleen Quirk has indicated that the company expects to move forward with the proposed expansion of its Bagdad copper mine in Arizona, marking a stronger commitment to the project ahead of a formal investment decision.
Speaking at the Jefferies Global Industrials Conference on September 10, Quirk said the project still requires input from Freeport's board but that she expects the company will proceed. She described the expansion as a roughly three-year construction project and noted that no major permitting hurdles are expected.
Freeport's latest project estimates put capital expenditure for the Bagdad expansion at approximately US$4.5 billion, around 30% above the previous US$3.5 billion estimate, reflecting cost escalation, scope changes and additional engineering.
The project would more than double concentrator capacity at Bagdad and is expected to add approximately 200–250 million lb, or around 91,000–113,000 tonnes, of copper production annually, alongside an additional 10–12 million lb of molybdenum. Bagdad currently has a reserve life exceeding 80 years.
Freeport's Q2 2026 regulatory filing had described the project as being prepared for a potential investment decision during the second half of 2026. The latest comments therefore represent a more positive signal from management on the likelihood of development, although formal board approval has not yet been announced.
A decision to proceed with Bagdad would represent one of Freeport's most significant near-term copper growth investments in the US. The potential addition of more than 90,000 tonnes per year of copper would materially increase Freeport's US output, although first production would remain several years away given the expected construction period. Attention will now turn to formal board approval and a final investment decision.
