Helicopters to Scan Wyoming and Colorado for Hidden Minerals

*Low-level helicopter flights will begin scanning the geology of Wyoming and northern Colorado started February 2025.*

In a groundbreaking initiative, low-level helicopter flights will begin scanning the geology of Wyoming and northern Colorado started February 2025. This airborne electromagnetic (AEM) survey, part of the Earth Mapping Resources Initiative, aims to create high-resolution 3D maps of underground mineral deposits, groundwater pathways, and geological structures.

Covering Albany, Carbon, Converse, Laramie, and Platte counties in Wyoming, as well as Jackson, Larimer, and Routt counties in Colorado, the helicopters will tow a large electromagnetic sensor resembling a hula-hoop to detect subsurface resistivity. This data will be critical in identifying mineral-rich zones, tracking groundwater flow, and enhancing land-use planning.

Aerial Science Expands Across the U.S.

This survey is part of a larger national effort that also includes similar missions over Michigan and Wisconsin. In these states, helicopters will scan the Penokean orogen and Midcontinent Rift System, searching for critical minerals essential for national security. The U.S. Geological Survey (USGS) has identified 50 key minerals necessary for economic stability, many of which are at risk due to supply chain vulnerabilities.

Through advanced airborne sensing technology, scientists can non-invasively explore underground formations, providing invaluable insights without disturbing the environment.

Paving the Way for Sustainable Resource Management

The data from these flights will play a crucial role in shaping future resource management. By producing detailed 3D geological models of up to 500 meters below the surface, geologists can better understand mineral deposits, assess environmental impacts, and support sustainable mining efforts.

As the U.S. aims to modernize its geological knowledge, these aerial surveys are paving the way for a data-driven approach to resource exploration—one that balances economic growth with environmental responsibility.
