An iron mining operation comprising four mines, the Davidson No. 1, No. 2, No. 3, and No. 4 Mines. Operations were started in 1911 by the Davidson Ore Mining Co. and continued through closure in 1947 by the Pittsburgh Coke & Iron Co., which assumed ownership in 1941. 8.3 million tons of ore were shipped.

Pickands Mining Co. leased the Davidson properties in 1947, and continued development in the No. 1, No. 2, and No. 3 Mines in combination with the James Mine through 1953.

The Davidson No. 1 Mine featured one shaft with five levels developed to 950 feet depth. The Davidson No. 2 Mine developed one shaft and four levels to 440 feet depth. The Davidson No. 3 Mine featured one shaft and three levels to 535 feet depth, but workings were deepened to 950 feet in combined operation with the James Mine. The Davidson No. 4 Mine, also known as Purcell or Wapama, had one shaft and workings to 220 feet. Production ceased at the No. 4 mine by 1922.
