Historic Sites and Points of Interest in Nevada County
A marker at the base of the mill reads:
Three Stamp Mill from the Red Ledge MineThis three stamp mill was donated to the City of Grass Valley by Mrs. Stella Tracy, owner of the famous Red Ledge Mine near Washington, Nevada County, where this mill crushed tons of gold bearing ore for many years.
It is erected here in memory of the "Cousin Jack" miners who came from Cornwall, England, with their knowledge of hardrock mining used to bring gold bearing quartz to the surface from the deep mines of this area.
