Ultramafic lands: Sustainability Challenges and Resource Opportunities
Ultramafic lands are geologically and ecologically diverse areas that host naturally elevated concentrations of chromium (Cr), cobalt (Co), iron (Fe), manganese (Mn), nickel (Ni), and scandium (Sc). While Cr is a potential carcinogen, Co, Mn, Ni, and Sc are considered critical minerals in the United States owing to their importance in current electric battery formulations. The research conducted...
21st Century Prospecting: AI-assisted Surveying of Critical Mineral Potential
The USGS Mineral Resources Program entered a partnership with the Defense Advanced Research Project Agency (DARPA). The partnership objective is to accelerate advances in science for understanding critical minerals, assessing unknown resources, and increase mineral security for the Nation so USGS can more efficiently assess critical mineral deposits within the United States.
Extracting data from maps: applying lessons learned from the AI for Critical Mineral Assessment Competition
This project will share techniques developed in two AI/ML competitions run in Fall 2022, Automated Map Georeferencing, and Automated Map Feature Extraction with USGS stakeholders. We will develop a strategy to operationalize successful approaches, benefiting any activity that uses legacy map data.
MinFrame - Methodological infrastructure needed for resource assessment, modeling, and evaluation
Assessing the mineral resources of the United States represents a core function of the Energy and Minerals Mission Area since the inception of the U.S. Geological Survey under the Organic Act of 1879. As reaffirmed by the Energy Policy Act of 2020, assessment of identified and undiscovered resources of critical mineral commodities continues to form a focal point of the Mineral Resources Program...
Mineral Resource Assessment Training
The USGS Mineral Resources Program conducts mineral resource assessments and is training USGS scientists in how to conduct these assessments for future work. As a practical exercise, the scientists will conduct an assessment for tungsten in the U.S.
