Colour: Silvery grey, metalic luster

Description: Magnetite was the main constituant or primary ore processed at Cornwall. The mines were in continuous operation, to varying degrees, from 1740, up to the time of it's closing and ranked as the longest continuing mining operation in the US. The mines were finally closed by flood waters created when Hurricane Agnes came through the area in 1972.
