Abandoned Mining in New Jersey

Federal databases record 1,022 abandoned, sealed, and historically closed mine locations in New Jersey. These include mines officially abandoned under MSHA oversight and past producers documented in the USGS Mineral Resources Data System.

Safety Warning: Abandoned mines are extremely dangerous. Hazards include cave-ins, toxic gases, flooded shafts, unstable ground, and hidden vertical drops. Never enter an abandoned mine. Many are on private property. If you discover an unsecured abandoned mine, report it to your state mining agency.
