Scattered across the United States, hundreds of thousands of abandoned mines scar the earth, posing a safety hazard to passing hikers and a health risk to nearby communities. But cached inside piles of refuse and ponds of toxic waste, there are also elements as critical for the 21st-century economy as coal was for the industrial revolution. Now, an obscure federal government program known as the Earth Mapping Resources Initiative, or Earth MRI, is identifying the high-tech minerals concealed in these mines — as well as those hidden beneath the Earth’s surface.
Developed by the U.S. Geological Survey, or USGS, during the first Trump administration, Earth MRI aims to comprehensively map the nation’s underground deposits of “critical minerals” — an ever-growing list of elements and compounds considered vital for national security and the economy. In 2021, Earth MRI received a massive funding boost through the bipartisan infrastructure law, accelerating federal scientists’ efforts to figure out which parts of the country are rich in minerals used in clean energy technologies, semiconductors, and high-tech weaponry. While the Trump administration has moved aggressively to reverse most of former President Joe Biden’s climate policies, it appears to agree with the prior administration’s desire to locate — and, eventually, mine — more of these resources.
Many Biden-era climate and energy initiatives remain in limbo following the Trump administration’s freeze on the disbursement of grant funding and mass firing of federal employees — but Earth MRI got an early greenlight to resume operations.
“This is a program that has survived both the Trump and Biden administrations,” Peter Cook, a critical minerals policy expert at The Breakthrough Institute, an environmental solutions research organization, told Grist. “They’re both definitely interested in critical minerals.”
