Richville was located between Lake Point and Tooele near the former site of E. T. City. Saw, woolen, and flour mills were built nearby and subsequently names were developed: Mills, Milton, Millvale, and Milltown. For a short period of time Richville was the county seat. After the county seat was moved to Tooele and the mills shut down, the community was abandoned. Today it is Mills Junction.
