National Map of Focus Areas for Potential Critical Mineral Resources in the United States

The U.S. Geological Survey (USGS) launched the Earth Mapping Resources Initiative (Earth MRI) to modernize the surface and subsurface geologic mapping of the United States, with a focus on identifying areas that may have the potential to contain critical mineral resources. Earth MRI can inform strategies to ensure secure and reliable domestic critical mineral supplies for the United States.

This fact sheet contains maps of focus areas and information about an important critical mineral (lithium) and the mineral systems and focus areas related to it.
