 The entrance to the stope of the Centennial Mine in 2005. |
Centennial or Squier's MineThe Centennial Mine was first worked in 1875. An ore body 12 feet in width was discovered through a series of eight pits and crosscuts. At its widest point the vein measured 38 feet wide. A total of five veins were discovered at approximately 5 feet in width and dipping 80 degrees southeast. 1,500 tons of magnetite ore were mined that year and the mine operated until 1879, possibly reopening briefly in 1880. In 1891, inventor Thomas Edison sent his own Superintendant of Mines to the Centennial Mine to determine whether its ore was suitable for his ore concentrating process. Ultimately it was the location of his NJ and PA Concentrating Works whereby his process was best utilized. |
