RESTON, Va. — The U.S. Geological Survey (USGS) and the Missouri Geological Survey are investing about $385,000, to conduct bedrock geologic mapping in the Cherokee Pass, Higdon and Marquand 7.5' quadrangles to develop geologic framework models for critical mineral evaluation.

The quadrangles are in the eastern St. Francois Mountains and contain a portion of the cobalt-rich Fredericktown-Mine La Motte sub-district of the Southeast Missouri Lead District. The world-class Southeast Missouri Mississippi Valley-type Lead District has associated zinc, copper, silver, cobalt and nickel mineralization in active and past-producing mines, making Missouri one of only nine states with potentially economically viable cobalt deposits.

The grants for the geologic mapping come from a $74 million investment allocated earlier this year to the USGS Mineral Resources Program’s Earth Mapping Resources Initiative (Earth MRI), provided through annual appropriations and investments from the Administration’s Bipartisan Infrastructure Law. Overall, the Infrastructure Law is providing an appropriated $510.7 million investment to the USGS to advance scientific innovation and map critical minerals.

The new geologic maps will refine our understanding of the geologic framework of mineral areas of interest. In addition to helping identify mineral potential, these maps also support both decisions about the use of land, water, energy and minerals, and understanding the potential impact of geologic hazards on communities.

Earth MRI is a partnership between the USGS and state geological surveys across America to modernize our understanding of the Nation’s fundamental geologic framework and mineral resources through new geologic maps, geophysical and topographic surveys, and geochemical sampling. The 2022 Bipartisan Infrastructure Law provided additional funding that has accelerated this new mapping in areas with potential for hosting critical mineral resources both still in the ground and in mine wastes.
