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.
This location is mapped as federal land. Public land is not an invitation to enter old workings. Ask the managing agency about access, claims and closures.
