This bill reauthorizes and expands the Earth Mapping Resources Initiative (Earth MRI), a federal program created to map and characterize subsurface resources across the United States. The legislation extends funding for the program through 2031, five years beyond its current authorization deadline, and broadens its scope to include advanced technologies like digital geochemistry and real-time data collection systems. The bill specifically adds focus on mapping critical minerals, geothermal resources, and natural hydrogen deposits, as well as incorporates the 3D Hydrography Program into the initiative's data integration efforts. This reauthorization affects the U.S. Geological Survey and other federal agencies involved in mineral and resource mapping, along with states and industries dependent on accurate subsurface resource data. The legislation was introduced by Senator Lisa Murkowski and Senator John Hickenlooper in June 2026 and referred to the Senate Committee on Energy and Natural Resources.
