HISTORICAL SITES / RESEARCH DIRECTORY
Find the public record behind a former mining site. Explore reported locations, mined materials and operating history as a starting point for acquisition, reuse or reclamation research.
History means records exist in the imported sources, including older periods. Missing history is not evidence of a clean safety record. Operator and controller names are the last relationships reported in the Mines snapshot; they are not verified current property owners.

Use the mine name and reported location to investigate county parcel and title records, mineral rights, access and planning constraints. MSHA mailing addresses are addresses of record and may not locate the mine. Confirm the parcel and current ownership separately.
EPA mine-site redevelopment primer ↗Check official reclamation inventories and state or tribal programmes for documented hazards, project status and programme criteria. A matching name or an MSHA abandoned status alone does not confirm a programme match.
OSMRE abandoned mine land programme ↗Source: MSHA public datasets. Production history checks quarterly and annual mine production/employment records. Safety history checks violations, inspections and accident reports; other source coverage is available on each mine profile.
