Report: The Blackbird mine is located three quarters of a mile east of Neihart and one quarter of a mile north of the Broadwater mine. There were not any tailings at the site and there was about 1,800 cubic yards of uncovered waste rock. There was an adit that held water but the water was not discharging. The pH of the water was 6.51. Samples showed that levels of cadmium and antimony exceeded MCL standards. There was not any surface water on the site.According to Robertson (1951) the Blackbird mine was a silver, lead, and zinc mine. The first development consisted of one shallow shaft and some open pits, and later, an adit was driven that was about 185 feet long. Drifts were driven from the adits to follow the veins.
