Summary

This data release provides descriptions of more than 60 mineral regions, mines, and mineral deposits within the United States and its territories that are reported to contain enrichments of cobalt (Co). To focus the scope of this data release, we report only mined deposits and exploration prospects with past production, or resource and reserve estimates of 1,000 metric tons or more of cobalt. Cobalt has diverse uses because of its properties, which include ferromagnetism, hardness, wear-resistance, low conductivity, and high melting point. The primary uses for cobalt are in rechargeable battery electrodes, and in superalloys used to make gas turbine engines. In 2017, the United States had a net import reliance as a percentage of apparent [...]

Purpose

This dataset is part of an ongoing effort by the U.S. Geological Survey (USGS) to understand the attributes and geologic distribution of critical mineral resources, both globally, and in particular, in the United States. The United States continues to become more dependent on imports to meet the domestic demands for an increasing number of mineral commodities. Many mineral commodities are now produced primarily or entirely outside of the United States, creating the potential for supply interruptions in the foreseeable future, or in the long term. These important but highly dependent mineral commodities are deemed critical and (or) strategic resources. Cobalt represents a prime example of a critical mineral resource. Cobalt is primarily used in cathodes for rechargeable batteries and in superalloys for jet turbine engines. Most cobalt is mined as a byproduct of copper or nickel, and recently cobalt prices have increased due to strong demand and limited availability. In some cases, there are possible substitutions for cobalt, however, in many applications, substitution would result in loss of performance. This dataset was compiled to provide base layers of information that identify and describe the known cobalt occurrences in the United States and its territories. This compilation is intended to contribute to our geologic understanding of cobalt deposits in the United States, and to assist in evaluating their resource potential.
