This 5 ½ Foot Diameter Drill Core

This 5 ½ foot diameter drill core came from the Cary Mine shaft from a depth of 2400 feet below the surface. The shaft was drilled during the period 1942-44 from surface to the 31st level and was later enlarged to its full size of 13X21 feet. Through the shaft, men, supplies and iron ore are transported between surface and the underground levels.
