Drawn as a mineral occurrence: a place where a geologist noted the mineral, with no mining recorded. The ore color stands for barium-barite. Federal records note the kind of operation and its status, not its depth or layout, so this is a typical example rather than a survey of this site.
This location is classified as a mineral prospect or occurrence — a site where minerals have been identified but no significant mining has taken place. These sites typically have minimal environmental impact but indicate the presence of mineral deposits in the area.
