3. Additional Plaque Indicating Gifting of Mine Remains to Amador City.
On the ruins is attached a plaque reading: "Gift from Henry and Mary Garibaldi, to the city of Amador City, of the headframe, hoist, and boiler located at the Keystone Mine. In memory of Henry Garibaldi's parents, Theresa and Peter Garibaldi." Although this plaque indicates city ownership of at least some of the ruins, the mine is private property and Sutter Gold Mining Company, Inc. may someday attempt to again extract gold ore from the Keystone Mine property.
