Mineral Resources Program

The United States continues to rely on foreign sources for some raw and processed mineral materials, including some critical minerals. This map shows the countries that supply mineral commodities for which the United States was more than 50% net import reliant in 2020. 

Map indicating flight area for Trans-Pecos aeromagnetic and radiometric survey. The survey area includes parts of El Paso and Hudspeth counties, Texas, and Otero County, New Mexico. Flights will begin in November 2020 and are expected to conclude in mid-January 2021. 

Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender. Gold sparks are produced by

The 43rd annual Mineral Commodity Summaries report from the USGS National Minerals Information Center is the earliest comprehensive source of 2019 world mineral production data. It includes information on the domestic industry structure, government programs, and tariffs as well as five-year salient statistics on more than 90 mineral commodities that are important to the U.

The Alaska North Slope is rich in gas hydrate-bearing formations which contain significant natural gas resources. The USGS has released a geologically based assessment for how much of these resources is technically recoverable.

To make America’s economy and defense more secure, the Administration has released “A Federal Strategy to Ensure Secure and Reliable Supplies of Critical Minerals.” Among other roles, these mineral commodities are vital to renewable energy infrastructure like solar panels, wind turbines, and batteries.
