[citation needed] Mason was established in the late 1890s, when the new Stamp Mill was built.

An article from the daily Mining Gazette from 12 December 1959 claimed 125 people occupied all 25 houses in Mason.

In an article "Mason....houses by the side of the road" 25 September 1981 cited "in 1900 a 2nd mill was constructed... meanwhile more larger houses were built and the first store was opened by Herman Radther in the kitchen of his home, and later a Bertha Chapell ran a store in a separate building, which was leveled by fire in 1940."

Bill and Ken Nelson operated a car lot (closed around 2002-2003) on the west side of Mason starting in the mid-1950s.

The reclamation plant produced 100,114,426 lbs of refined copper metal during its 24 years of service.

Mason and the Quincy mill / reclamation area is also officially on the National Register of Historic Places.
