Other names: Kennedy Mining and Milling Company; Kennedy Mining Company; Humbug Hill; Kennedy Quartz Mining Claim; The Gate
Amador County, CA
The Kennedy Mine is eligible for listing in the National Register of Historic Places under Criteria A and C at the state level of significance. The district retains an exceptional degree of physical integrity. It is significant as an excellent example of quartz mining operations during California's signature mining era, operating almost continuously from the gold rush until World War". The property bears testament to the quartz mining on the Mother Lode, and the importance of gold mining to the surrounding communities and history of California. But most importantly, the Kennedy gold mine helped shape the character of cities of Jackson and Martell, both culturally and economically.
The Kennedy gold mine was one of the largest mines in California and is unique in that it produced the most gold of any mine not only along the 20-mile-long belt referred to in "Gold Districts of California," but along the entire 120 mile-long length of the Mother Lode. The amount of gold produced by the Kennedy Mine is approximately $28,600,000. Most of that production occurred while the price of a pure ounce of gold was $20.67 an ounce. Its total production over the years resulted in dividends on an original capitalization of $100,000, making it one of the blue chip investments of the day. Sons and daughters of Jackson miners have often related the story that Jackson and Amador County were economically unaffected by the depression in the late 1920s and early 30s because the gold mines in the area kept operating continuously throughout that time period.
The Kennedy Mine is also unique in that, at 5,912 vertical feet, it was also the deepest mine in North America while in operation.
