Keystone Mine, Amador City, Amador County

In 1920 the Keystone Mining Company gained control of the South Spring Hill mine which adjoins the property to the east; however, very little was done until l933 when the Keystone was re-opened by the Keystone Mines Syndicate. After two years of rehabilitation and development work production was under way in 1935 and continued until the fall of 1942, when the Keystone, as all other gold mines, was closed down by government order. During this final seven years of operation about one million dollars in gold was produced.


With the exception of a small amount of work done in 1952 in the neighboring Wonder mine just east of the main shaft nothing has been done at the Keystone since the beginning of World War II.

Other than that little else remains. The surface works have been junked. The shaft has caved. The famous old Keystone is now just another abandoned mine.

There is now plans in the works to re-open this mine in the next few months - more to come.
