Episode summary
Why the US Is Pushing to Rebuild Its Copper Supply
Wall Street Week
· · 11 min · Hosts: Chrystia Freeland, David Westin
Summary
Copper demand is rising sharply as AI data centers, power grids, defense spending, and clean-energy buildouts all require more metal. The episode centered on Rio Tinto’s Resolution Copper project in Arizona, which could eventually produce up to 40 billion pounds over 40 years and supply roughly a quarter of projected U.S. demand. The guests argued that the U.S. has abundant copper in the ground but lacks the time, capital, and permitting speed to turn deposits into usable supply.
The discussion emphasized how far the U.S. has fallen behind in processing as well as mining. The country has only two operating copper smelters, imports about 57% of its refined copper, and has seen mine development stretch to nearly 29 years on average from discovery to production. China’s dominance in refining and processing was presented as a strategic vulnerability, while scrap recycling was described as helpful but too small to close the gap.
The core argument was that copper is becoming a national-security issue as much as a commodity story. Near-record prices are encouraging new investment, and the guests suggested that regulatory relief could help, but time remains the main constraint. The episode framed domestic copper as essential infrastructure for the next phase of U.S. economic growth.
Key takeaways
- The guests said Resolution Copper could produce as much as 40 billion pounds over 40 years, enough for roughly a quarter of projected U.S. demand.
- An analyst said U.S. copper demand is expected to rise over 40% by 2040, driven by data centers, transmission, and clean technologies.
- The U.S. has only two operating copper smelters in 2026 and imports about 57% of its refined copper, according to the episode.
- A guest argued that new U.S. mine development takes nearly 29 years on average, making speed the biggest bottleneck.
- Scrap recycling helps, but an industry executive said it is only incremental and will not close the roughly million-ton refined-copper gap.
Notable quotes
“-The deposit is incredible. It's two billion tons at one and a half percent copper”
“By 2040, demand is expected to rise over 40%”
“-Our ability to bring on new supply is critical and our ability to keep the smelters we do have full is really a national security issue”
“-The U.S. has more than 275 million metric tons in reserves and resources comparable to Canada and Australia combined”
“you can't build them without copper”
How the episode opens
-An hour east of Phoenix, Arizona. Might be a little too big. -We kind of reconditioned and repurposed a lot of old mining equipment.
-More than a mile beneath the desert surface. -You get more comfortable once you're standing on the ground and you'll forget that you're so far below the ground. -The mining giant Rio Tinto thinks it's found one of the largest undeveloped copper deposits in the world.
We had a chance to tour the facility back in late March. The Resolution Copper Mine sits on an ore deposit that may produce as much as 40 billion pounds of the metal over 40 years. -This is brand new.
-It's enough to meet roughly a quarter of projected U.S. demand. It lies almost 7,000 feet under the surface, just over a mile, equivalent to four and a half Empire State buildings.
We went down into the mine with Resolution Copper's president, Vicky Peacey. -The deposit is incredible. It's two billion tons at one and a half percent copper.
It's the second largest undeveloped copper deposit in the world. That's 25% of the U.S. demand for copper.
And the grade is very high, one and a half percent. Most of the copper that's mined in the U .S. today from a handful of mines that are very old, over 100 years, are less than half a percent of copper.
So this is quite a rich deposit and it will be operated for decades. -It's hard to overstate how dire the copper shortage is in this era of AI. Copper use is soaring, particularly for data centers and defense.
By 2040, demand is expected to rise over 40%. -We haven't seen a response on supply increasing by 50% year on year. Ultimately, if you want economic growth, if you want data center buildouts, if you want defense buildups, you know, you need copper.
