Freeport-McMoRan's board has approved a $4.5 billion expansion of its Bagdad copper and molybdenum mine in Arizona. It would lift annual copper output by about 225 million pounds to more than 400 million pounds, with first production targeted for mid-2030.
At a glance
- The cost is about $1 billion, or 29%, above a 2023 estimate of $3.5 billion, which Freeport blamed on cost escalation and scope changes.
- Molybdenum output would rise by about 12 million pounds a year to more than 20 million pounds.
- Freeport expects long-term unit net cash costs to fall by about 20%.
Background
Bagdad is a copper and molybdenum mine in northwest Arizona that has operated since 1945, with reserves for more than 80 years. In 2025 it became the first major US mine with a fully autonomous haul-truck fleet. A brownfield project expands an existing mine rather than building a new one. Unit net cash cost is the cost of producing a pound of copper after by-product credits.
What happened
Freeport-McMoRan's board approved a $4.5 billion expansion and modernisation of its Bagdad operation in Arizona on Wednesday, the company said. The project would more than double Bagdad's mining and milling rates.
Annual copper output would rise by about 225 million pounds to more than 400 million pounds. That would make Bagdad the second-largest US copper mine after Freeport's Morenci. Construction will take about three and a half years, with first production targeted for mid-2030.
Why Freeport is expanding now
Chief executive Kathleen Quirk called it a low-risk brownfield project that builds on Bagdad's reserves, infrastructure and workforce. Freeport says the project's economics work at a copper price of about $4 a pound, The Northern Miner reported.
The cost is about $1 billion, or 29%, above the $3.5 billion estimate prepared in 2023. Freeport blamed cost escalation, changes in scope and revised estimates after more engineering work.
BMO Capital Markets analyst Katja Jancic said the approval was largely expected, with costs, output and timing in line with earlier guidance.
What it means for US supply
The project adds concentrators to process about 115,000 tonnes of ore a day, plus a new crusher, conveyor, water pipeline and power line. Freeport expects to spend about 20% of the cost in 2027, 30-35% in 2028 and the rest in 2029-2030.
Net imports supplied 57% of US refined-copper consumption in 2025, according to US Geological Survey data cited by The Northern Miner. Bagdad's extra output would add domestic supply from 2030.
Our read
Outlook: neutral. The extra copper is not due until mid-2030, so near-term supply is unchanged.
What to watch
- Freeport's updated capital spending outlook, which will include Bagdad.
- Cost inflation, which Freeport says could affect its estimates.
- Early works and procurement before full construction starts.

Detailed analysis
Timeline
- 2026-11-04: Freeport's board approves the $4.5 billion Bagdad expansion.
Supply Drivers
The expansion adds about 225 million pounds of US copper and 12 million pounds of molybdenum a year.
Inflation
Cost escalation lifted the project budget 29% above the 2023 estimate.
Mining Production
Bagdad's copper output would rise to more than 400 million pounds a year from mid-2030.
What could lift prices
- The project's cost rose 29% from 2023, showing how expensive new copper supply has become.
- No extra copper arrives from Bagdad until mid-2030.
What could weigh on prices
- Bagdad would add about 225 million pounds of copper a year from 2030.
- US policy is pushing for more domestic copper supply.
Country impact
| Country | Impact | Reason |
|---|---|---|
| United States | High | Bagdad would become the second-largest US copper mine. |
| Chile | Low | Chile supplied 68% of US refined copper imports in 2021-24. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Copper Mining | Positive | Freeport is committing $4.5 billion to expand an existing US mine. |
Who gains, who loses
- US copper buyers: Bagdad would add domestic supply in a market where net imports met 57% of demand in 2025.
- Freeport shareholders: The company must fund $4.5 billion of spending, mostly from 2028 to 2030.
Other ways this could play out
- If costs keep rising, Freeport's estimate could increase again, as it has warned.
- If built on schedule, Bagdad would become the second-largest US copper mine from 2030.
Price risks
- Inflation and cost escalation could raise the budget.
- Construction delays would push back new US copper supply.
Technical view
Price is trading below both its 20-period and 50-period moving averages, a bearish alignment.
