Source: USGS Mineral Resources Data System (retrieved 2026-10-13). The database was last updated around 2011, positions can be approximate, and "producer" does not mean a mine is operating today. "Output class" is a code whose meaning changed over the years, so compare sites inside this data and do not read it as tonnage.

Land status comes from the BLM Surface Management Agency dataset and can be out of date. Check ownership before you go near any mine site.
