Development of the Quartz Stamp Mill in California

The most productive quartz-mill during the 1850s and 1860s, in the state of California was the Benton mill, on Fremont's Ranch, in Mariposa County. It was also the largest, having forty-eight stamps. There were four mills on the estate, with ninety-one stamps in all, and their average yield per month is sixty thousand dollars.
