Nivloc was a short lived one saloon mining camp. The name Nivloc is from the name of one of the first mine owners (Colvin) spelled backwards. Gold was discovered here in 1907 by an Indian, but did not stay in operation very long. The mine was reopened once again in the 1930s, with the height of operation being the period 1940-43, when a post office was erected here. It resumed operations once again after WWII, and has experienced intermittent operation since.
