Freeport-McMoRan Approves $4.5B Bagdad Copper Mine Expansion in Arizona
Freeport-McMoRan has approved a $4.5 billion expansion of its Bagdad mine in Arizona, targeting more than 400 million pounds of annual copper production and lower operating costs. Initial production from the expanded operation is expected in mid-2030.

Key Points
- $4.5 billion investment: Freeport will more than double mining and milling rates at its Bagdad copper and molybdenum operation.
- Major production increase: Annual copper output is projected to exceed 400 million pounds, with molybdenum exceeding 20 million pounds.
- Construction and employment: More than 4,000 direct and indirect construction jobs are expected, with initial production targeted for mid-2030.
SEATTLE (Scrap Monster): Freeport-McMoRan has approved a $4.5 billion expansion and modernization of its Bagdad copper and molybdenum mine in northwestern Arizona, advancing one of the company's major U.S. copper growth projects.
The investment is expected to more than double the operation's mining and milling rates, positioning Bagdad as the second-largest copper mine in the United States, behind Freeport's Morenci operation.
Once fully developed, annual copper production is projected to exceed 400 million pounds, an increase of approximately 225 million pounds. Molybdenum output is expected to exceed 20 million pounds annually, including about 12 million pounds of additional production.
SCRAPMONSTER EDGE | COPPER SUPPLY ANALYSIS
A Major U.S. Copper Supply Addition, but Not Until 2030
The expansion is projected to add 225 million pounds of copper annually, equivalent to approximately 102,000 metric tons of additional production each year.
That would materially increase Bagdad's output and strengthen Freeport's U.S. copper production base. However, the expected mid-2030 startup means the project will not provide immediate relief to near-term copper supply constraints.
Industry takeaway: For copper processors, manufacturers and industrial buyers, Bagdad represents a significant longer-term domestic supply development. Its market impact will depend on construction progress, commissioning, production ramp-up and actual operating costs.
New Concentrator and Infrastructure to Double Capacity
The modernization program includes new concentrator facilities with approximately 115,000 metric tons per day of additional processing capacity.
Planned infrastructure includes a primary crusher, overland conveyor, water pipeline, power line, additional mining equipment and supporting facilities.
Freeport will also leverage automation and modern mining technology. Bagdad became the first major U.S. mine with a fully autonomous haulage fleet in 2025, providing an established platform for further productivity improvements.
The company expects the expansion to reduce long-term unit net cash costs by approximately 20% through greater operating scale, improved technology and molybdenum by-product credits.
Freeport Builds on Bagdad's Existing Reserves
Freeport president and chief executive Kathleen Quirk described the project as a relatively low-risk brownfield investment, supported by the mine's substantial resource base, existing infrastructure and experienced workforce.
Bagdad has operated since 1945 and has an estimated reserve life exceeding 80 years at current operating assumptions, before considering additional mineral resources.
The expansion is designed to support the company's domestic copper and molybdenum growth strategy while improving the mine's long-term cost competitiveness.
Construction to Take 3.5 Years, With Startup in 2030
Construction is expected to take approximately three and a half years, with initial production targeted for mid-2030.
Freeport estimates that approximately 20% of the project budget will be spent in 2027, followed by 30%–35% in 2028, with the balance allocated during 2029 and 2030.
The development is expected to support more than 4,000 direct and indirect construction jobs, alongside longer-term employment opportunities.
The $4.5 billion capital estimate remains subject to potential cost escalation, inflation and construction execution risks.
