America’s fastest-growing industries increasingly rely on copper.

The critical minerals Rio Tinto produces play an essential role in making modern life work and help power the clean energy transition, said Rio Tinto Copper Chief Operating Officer Clayton Walker. “Think of increasing demand for things like electric vehicles, the copper plumbing in our houses … transmission lines, smartphones, electronic devices—the things you can’t live without all include copper.”

This criticality was brought home to the NAM during a site visit by leadership last Friday to the company’s Resolution Copper mine, an Arizona project with the potential to supply up to 25% of the nation’s copper demand.

Electrifying a revolution: Rio Tinto—which produces more than 10 different minerals and metals around the world—has copper operations in Utah and Mongolia with joint ventures in Chile and Peru and is working to open Resolution Copper and another copper-mining site in Australia.

• These operations are going to become increasingly important as the world’s appetite for EVs grows, Walker told the NAM, because EVs require more copper than traditional vehicles.
• EV charging stations also require the metal, as do wind turbines, which “can contain up to 4.7 tons of copper,” according to Walker.

Speed permitting now: The U.S. consumes about 2 million metric tons of copper per year but produces just more than 1 million metric tons. However, “by 2035, that demand is estimated to be around 4 to 5 million tons of copper a year,” said Walker. “The question is, where are we going to get all that additional copper?”

• The answer, in his opinion, should be here at home. Once approved, Resolution Copper will be instrumental in making that happen. “The copper produced at Resolution would strengthen U.S. supply chains, reduce import dependency [and] add jobs, while employing world-class sustainability standards.”
• At that site, “we’ve been working on permitting for the last 11 years,” Walker continued. “The average time to permit [a mining project] in the U.S. is 17 to 20 years. That’s a long time. We’re not asking people to cut corners, but could we speed that process up?”
