Scrub Oaks Mine


The Scrub Oaks Mine is likely the largest iron mine in all of New Jersey. Since 1939, an average of more than 200,000 tons of ore were mined each year up until 1950 when a total life long production of 3.7 million tons was attained. From this, it can be reasoned that over 7 million tons were produced by the time it was permanently abandoned in 1966.

The mine, first worked in 1856, was opened by a series of shafts. Operations ceased in 1873 and in 1880, it resumed in the form of a pit and adit. Although the ore was plentiful, it was also lean and it was not until 1917 that the mine was worked vigorously due to improvements in technology.
