U.S. Geological Survey is a geoscience agency operating under the United States Department of Interior. The USGS is a research organization with no regulatory responsibility, and as the United States’ largest water, earth, and biological science and civilian mapping agency, the USGS collects, monitors, analyses, and provides science about natural resource conditions, issues, and problems. The Mineral Resources Program (MRP) conducts unbiased research and assessments at regional, national, and global scales that focus on the location, quantity, and quality of mineral resources, including the economic and environmental effects of resource extraction and use. The role of USGS will be essential in both the development and testing phases of the assessment methodology and software. The key contributions of USGS in the project are the software code for computing estimates of undiscovered mineral resources, as well as assistance with the development, testing and documentation of methods and tools developed in the project.
