The USGS Methodology for Identifying Critical Minerals 

"Critical" has become a frequently used buzzword attached to minerals, but what makes a commodity critical? Governments, corporations, and other stakeholders all have different requirements which makes a single definition challenging. This talk will address the geological, economic, and strategic factors the US Geological Survey has considered to develop the methodology used for the federal government's Critical Minerals list.
