Nipissing Mine

The Nipissing Mine is an abandoned silver mine in Cobalt, Ontario, Canada, located on Nip Hill on the east side of Long Lake.

It was developed in the subsequent Cobalt silver rush of 1903. The original 843 acres of claims were purchased by Ellis P. Earle from the Ferland Syndicate. By 1907, it was the top producing mine in the area. The company completely surrounded Peterson and Carr lakes and occupied the east side of Cobalt Lake. At its peak, the mine had ten shafts working three veins, the Kendall, Meyer and Fourth of July. Additionally, it used hydraulics to strip the overburden and employed an aerial tramway. The last dividend was paid in 1921 however.
