Gnesda, W.R., Karl, N.A., and Mauk, J.L., 2020, Germanium deposits in the United States: U.S. Geological Survey data release, https://doi.org/10.5066/P9CPYTFN.

Summary

This data release provides data for the single site in the United States (U.S.) that has public record of germanium (Ge) production. Germanium, which is currently classified as a critical mineral in the U.S., is also extracted as a byproduct from deposits in Alaska, Washington, and Tennessee. However, there is no public information that documents germanium production from these deposits. Current annual production of refined germanium is led by China at 85,000 tons, while estimates place U.S. reserves near 2,500 tons. Reported production of germanium in the U.S. is limited to one site, the Apex mine in Washington County, Utah. The Apex mine produced gallium (Ga) and germanium as primary products during the mid-1980s. Since its closure, [...]

Purpose

This dataset was developed as part of an ongoing effort by the U.S. Geological Survey to inventory public information on critical mineral deposits within the United States that have public record of production and (or) resources above a specified cutoff limit. In the case of germanium there is no cutoff limit since there is only one deposit with public record of production. The geospatial data provide location, geologic description, and production and resource information. In general, USGS uses this information to delineate permissive tracts (geographic areas in which specific types of mineral deposits may occur), develop assessments of potential undiscovered mineral resources, determine where and how the environmental effects of mining may be observed, and understand the natural variability found in mineral deposits of particular types. The data also support the Federal strategic objective to secure reliable supplies of critical minerals by providing information for geoscience research and mineral exploration to State and Federal agencies, private industry, and the general public.
