The U.S. Geological Survey (USGS) is offering an innovative and economically strategic opportunity for states across the nation. Through $5 million in cooperative agreements, the USGS aims to explore the hidden potential within the mountains of waste material left behind by decades of mining activities. This initiative, under the Earth Mapping Resources Initiative (Earth MRI), encourages state geological surveys to collaborate in reassessing both active and abandoned mine sites to identify critical minerals essential to the future of the U.S. economy and national security.
Mine waste, often seen simply as an environmental problem, now holds the promise of valuable critical minerals. Tailings and waste rock piles—previously discarded as worthless residue—may contain germanium, rare earth elements, and other materials indispensable for advanced technologies. Germanium, for instance, is crucial in the production of high-performance computer chips, integral to modern electronics and emerging industries. Historically processed alongside zinc ores, germanium may still reside unnoticed in waste piles, overlooked because its significance wasn’t known or valued at the time mining originally occurred.
The funding offered by the USGS will directly support state geological surveys in cataloging, sampling, and analyzing mine waste to identify these overlooked mineral commodities. Additionally, this collaborative effort aims to build a comprehensive national mine-waste inventory, enhancing the understanding of the economic and environmental potential stored within these sites. Beyond just economic benefits, the assessment of mine waste can guide future decisions around remediation, managing environmental hazards, and potentially repurposing mine waste sustainably.
A recent exploration conducted by the USGS illustrates the promising potential of such initiatives. Legacy iron mines in the Adirondack Mountains in New York, once believed to be depleted, have been found to contain substantial amounts of rare earth elements. Such discoveries underscore the hidden value that renewed investigation of mine waste sites can reveal. These elements are increasingly essential for clean energy technologies, defense systems, and modern manufacturing, further emphasizing the strategic importance of this project.
Interested state geological surveys are encouraged to apply through grants.gov (Funding Opportunity Number G25AS00258) by May 14, 2025. Through Earth MRI, partnerships between states, academia, private sector entities, and federal agencies are transforming America’s approach to mineral resources. By funding this competitive grant program, the USGS demonstrates its commitment not only to securing critical mineral supplies but also to advancing national economic security and technological leadership through innovative resource management.
