Earth MRI geologic mapping program would run through 2031, adding geothermal and hydrogen

What does this do?

The bill would extend the Earth Mapping Resources Initiative, run through the U.S. Geological Survey, for 2027 through 2031. The program maps the geology underneath the country to show where critical minerals may be found. The bill would also allow newer technology in the mapping, add geothermal energy and natural hydrogen as resource targets, and add the 3D Hydrography Program to the program's list of data sources.

Who does it affect?

The main groups affected are federal and state geologists, mining and energy companies, researchers, and others who use geologic maps to plan projects or study resources.

Why does it matter?

The program's funding authority is set to run out after 2026, so the extension would keep Congress able to fund it for another five years. The updates would change what technology, resource types, and data sources the mapping can use.

What does it cost, and who pays?

• No dollar amount set
• Extends funding authority 2027-2031
• Money approved separately
