The USGS delivers unbiased science and information on mineral resource potential, production, consumption, disposal, and how minerals interact with the environment. The USGS National Minerals Information Center provides the Nation with data on domestic and global supply, demand, and trade for minerals and materials. This information is essential to understand mineral dependencies across economic sectors, forecast potential disruptions to mineral commodity supply, and evaluate the impacts of such disruptions.
