A very old copper mine. The American Revolutionary Army briefly operated a copper mine from an outcrop in the area of Chimney Rock and produced one brass cannon from the proceeds according to legend. A copper mine operated at the contact between the Watchung basalt and the underlying sedimentary rocks, as with the Pluckemin and American mines. The workings of this old mine were encountered during quarrying operations at the Chimney Rock quarry as early as 1906. The encounters with the copper bed continue today. Recently a specimen of native copper weighing over 800 pounds (380 kg) was recovered and donated to the Sterling Hill Mining Museum, where it is on exhibit. NOTE: Trespassing at this location is strictly forbidden and enforced. Violators are arrested.
