In current weeks, you have probably heard rather a lot about rare-earth substances, because of President Trump’s stalled efforts to safe a minerals cope with Ukraine and his discuss of annexing Greenland. These important substances gasoline the rising renewables and electric-vehicle industries. Nonetheless, many consultants warn that the scarcity of one other essential metallic, utilized in electronics, wiring and even plumbing may very well be simply as regarding.
Copper could also be much more essential to the nation’s shift towards a greener, extra environment friendly financial system than uncommon components like neodymium or praseodymium. Whereas copper has been mined for 1000’s of years, the demand for it has surged previously twenty years, driving its worth up practically 75% since 2020.
But, regardless of its significance, the world’s largest copper mines in areas like Chile, Peru and the Democratic Republic of the Congo (DRC) are struggling to fulfill demand amid a worldwide scarcity, all whereas grappling with escalating environmental issues.
Cassandra Cummins, the CEO of New Jersey-based Thomas Instrumentation, has needed to issue within the steep enhance in copper that goes into the circuit boards and different digital elements that the family-owned agency manufactures for business purchasers.
She explains that whereas the microchips the corporate makes use of include uncommon earth minerals, round 90% of a completed circuit board is copper. Take LEDs, for instance: whereas the uncommon earth ingredient terbium makes them shine inexperienced, “it is a tiny fraction in comparison with the quantity of copper on the board,” she says. “But when we do not have copper, if my suppliers do not have copper, then we do not have boards.”
The rising price of copper lately has considerably elevated the worth of these completed boards for Thomas Instrumentation’s prospects. “We apologize, however we now have to extend costs,” Cummins says.
It is an issue that can solely worsen. A report final yr by S&P International blamed the shortfall on a variety of issues, together with underinvestment in new exploration and mines because of the trade’s deal with short-term returns.
BHP, a Melbourne, Australia-based multinational mining and metals firm says that current mines will produce round 15% much less copper in 2035 than in 2024. The typical grade of ore has additionally diminished by round 40% since 1991, BHP says.
“Many of the high-grade stuff’s already been mined,” says Mike McKibben, an affiliate professor emeritus of geology at College of California, Riverside. “So, we now have to go after more and more decrease grade materials” that price extra to mine and course of, he says.
That is a recipe for increased costs and unmet demand, says Shon Hiatt, a enterprise professor on the College of Southern California. “It is projected that within the subsequent 20 years, we are going to want as a lot copper as all of the copper that has ever been produced as much as this date,” he says.
Copper’s potential to be recycled performs a big position in easing some provide challenges, nevertheless it’s removed from adequate. Solely round one-third of the copper provide within the U.S. comes from recycled materials.
The U.S. already imports half of the copper it consumes from nations together with Canada and Mexico. Like aluminum and metal, copper is poised to be swept up within the White Home commerce struggle. Final month, the president ordered an investigation into copper imports from Canada, and U.S. Commerce Secretary Howard Lutnick has confirmed that Trump will add copper to the 25% tariffs on Canadian metal and aluminum.
President Trump holds an government order, alongside Secretary of Well being and Human Providers Robert F. Kennedy Jr. (left) and Commerce Secretary nominee Howard Lutnick, within the Oval Workplace on Feb. 25. Trump signed an government order on the availability of copper and overseas copper within the American market, charging Lutnick with taking a look at a course of to doubtlessly impose tariffs or commerce obstacles.

Opening new mines is not simple. Final yr, China lastly broke floor on a copper mine in Afghanistan after 16 years of delays. Within the U.S., there are environmental and social issues and an usually prolonged allowing course of, in keeping with Simon Jowitt, a geologist and the director of the Nevada Bureau of Mines and Geology.
“Mining traditionally has not had status for doing the correct factor on the atmosphere … particularly large-scale open pit mines like in Arizona, like right here in Nevada, like Utah,” he says.
Stuart Burgess, chairman and co-founder of Sandy, Utah-based Burgex Mining Consultants, says his workforce is the “boots on the bottom” that bodily stakes new mining claims for firms. “We’re seeing a whole lot of curiosity in copper, notably right here in the USA,” he says.
He notes that it takes 4 occasions as a lot copper to make an electrical car as a gas-powered one and that charging all these EVs would require large upgrades to the ability grid, additional straining the demand-side of the copper equation. “If we take all of the identified deposits on the earth which can be confirmed … it will in all probability meet half that demand by 2050,” he says.
There are methods to squeeze out efficiencies, however solely on the margins, Burgess says. “All people appears to be like for that magic black field the place you’ll be able to put one copper ingredient in and get two out. It would not exist,” he says.
Nonetheless, it could possibly take a decade or extra to develop new sources of copper into productive mines, Jowitt says. Even then, there aren’t any ensures. Take for instance the deliberate Decision Copper Mine in Arizona, which has been caught up in a greater than decade-long authorized and political battle that has drawn in three presidents over issues voiced by the state’s Native American tribes. One other deliberate copper mine in Arizona and two in Minnesota have run into vital delays.
Apache Leap Mountain hovers over Superior, Ariz., on June 9, 2023. The historic mining city in central Arizona is the topic of a tug-of-war between locals who need a copper mine developed close by for financial profit and Native American teams who say the land wanted for mining is sacred and must be protected.

The ore in Decision is not on the floor, the place it may be strip-mined, however 6,000 toes underground, the place the prices of extracting copper “are three to 4 occasions costlier,” Burgess says.
Even when new mines will be opened, the U.S. solely has two working copper smelters to deal with the uncooked ore — one in Arizona and one other in Utah. They’re “already operating at capability,” Jowitt says.
“There’s potential for far more copper right here, however we do not have sufficient smelting capability,” he says. “Even when new mines come on-line, the difficulty is the place we are going to course of it.”
Canada has been the reply till now, however that may simply be disrupted if the present commerce struggle heats up any additional, he worries.
“We’re shedding pleasant relations with these locations that might truly do the copper processing,” Jowitt says. “You’ve got acquired the mine, however you want that intermediate step earlier than you can begin placing that copper into copper wiring, into our electrical autos, into no matter you wish to put it in.”
