HistoryThe Malachite Mine was primarily a copper mine on an 80-acre tract along Bear Creek. Its mill site occupied 10 acres on Bear Creek. The mine's approximate production was $35,000. Its ore was described as massive and consisted of coarse masses of chalcopyrite, zinc blende and pyrrohite, and some nickel. It contained very little gold or silver. Dike runs generally in an east-west direction in a gravite schist formation. There are two tunnels 350 feet in length, a shaft 150 feet in depth and an open cut measuring 15 by 25 feet, 15 feet deep and shows a vein on the surface to be 4 feet wide.
