RESTON, Va. – The U.S. Geological Survey (USGS) is now soliciting proposals for fiscal year 2024 cooperative agreements with the Alaska Division of Geologic and Geophysical Surveys to fund geospatial mapping projects across the Kuskokwim Mountains through the Earth Mapping Resources Initiative, known as Earth MRI.

The $4.25 million funding opportunity is the result of investments by the Bipartisan Infrastructure Law to support ongoing efforts to improve our knowledge of the geology of the United States and to identify areas that may have the potential to contain undiscovered critical mineral resources. 

This year’s funding will finance airborne geophysical surveys around the Western Kuskokwim River in the southwestern part of the state, which has previously been identified as hosting critical mineral resources. The surveys will produce high-quality magnetic and radiometric maps which can be used by state, federal and private entities to identify locations with potential mineral resources. 

Interested state geological surveys can apply online at GRANTS.GOV under funding opportunity number G24AS00355. Applications will be accepted through Dec. 31, 2024.
