Commodities (Major) - Copper
Development Status: Past Producer
An underground copper mine consisting of three shafts located near Delaware. The Pennsylvania Mining Company was organized in 1861 after splitting off from the Northwest Mining Company. The company began work on the Pennsylvania Fissure which consisted of three separate veins crossing their property. Shafts were sunk on each vein after rich copper deposits were discovered. The mine had a relatively short life, partly because company management spent their entire capital on surface improvements instead of mining, and the mine closed in 1866. Most of the piles were removed in the 1990’s for road improvements. What is left can be a challenge to find, but once found, copper and datolite can be recovered.
