What is Earth MRI?
The USGS Earth Mapping Resource Initiative (Earth MRI) is a partnership of the USGS, the Association of American State Geologists and other governmental, Tribal and private sector entities to update the nation’s surface and subsurface mapping, to improve our knowledge of the geologic framework in the United States and to identify areas that may have the potential to contain undiscovered critical mineral resources.

What is a critical mineral?
The Energy Act of 2020 defined critical minerals as those which are essential to the economic or national security of the United States; have a supply chain that is vulnerable to disruption; and serve an essential function in the manufacturing of a product, the absence of which would have significant consequences for the economic or national security of the U.S. The act further specified that...
Where can I find information about mineral commodities?
For statistical information about mineral commodities, visit the USGS Commodity Statistics and Information website. For locations outside the United States, USGS International Minerals Statistics and Information is the best starting point.
How do we extract minerals?
The primary methods used to extract minerals from the ground are: Underground mining Surface (open pit) mining Placer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use. Higher-grade metallic ores found in veins deep under the Earth’s...
What is the National Geologic Map Database?
The National Geologic Map Database (NGMDB) is an archive of geoscience maps (including geology maps), reports, and stratigraphic information for the United States. The NGMDB contains information on more than 90,000 maps and related geoscience reports published from the early 1800s to the present day, by more than 630 agencies, universities, associations, and private companies. Much of the content...
Are there geologic maps or publications for where I live?
Detailed geologic mapping has not been completed for the entire United States, but maps are available for most locations. Geologic maps at many scales and from many sources are listed in the National Geologic Map Database . Some geologic maps can be purchased in hard copy through the USGS Store . Download digital geologic maps for entire states from the USGS Mineral Resources Online Geospatial...
