Amador County was the most productive of “The Mother Lode” counties. This county produced approximately 6,500,000 ounces of placer gold and 7,700,000 ounces of lode gold. Mining continues today. The richest area in this county is about 1 mile wide across the west central part of the county from the south to the north. The Old Eureka Mine had the deepest shaft in America at 1,3500 feet deep and it was the largest producer in the mother lode in the early days. The Kennedy Mine, Argonaut Gold Mine, and Keystone Mines were also large gold mines in the same area. Nowadays, Amador County is famous for it wineries.
BIG INDIAN CREEK: Sizable dredging and drift operations between 1850 – 1950 produced about 100,000 ounces of placer gold near Fiddletown along Indian Gulch which goes into Big Indian Creek. Big Indian Creek is said to contain Placer gold in large quantities. Around the Plymouth area is said to be rich.
DRY CREEK: Off of the beaten path is Dry Creek. It might be worth the hike in. Dry Creek is known for pickers and chunky sized gold.
COSUMNES RIVER: Close to the town of Plymouth, in the west central part of the county there were many placer operations that produced tens of thousands of ounces of placer gold. The Loafer Hill mine, near Oleta, had several small gravel deposits that produced well.
JACKSON CREEK: Near the town of Jackson, you will find the Gwin Mine, it produced lode gold in masses of crystallized arsenopyrite. These are great specimens. Jackson Creek reportedly contains placer gold.
MIDDLE FORK OF THE MOKELUMNE RIVER: Hydraulic operations were located on this river that produced considerable placer gold.
NORTH FORK OF THE MOKELUMNE RIVER: Hydraulic operations were located on this river that produced considerable placer gold. Near Volcano, in the west central part of the county around Jackson Gulch and Ranchero Gulch, there were some very rich placer deposits.
