The History of the Kennedy Mine


The Discovery

The Kennedy Mine, Jackson CA The history of the Kennedy Mine is traced to January 4, 1860 when Andrew Kennedy, John Fullen, James Fleming, and James Berringan filed four mining claims, each 120 feet long, in the vicinity of today’s Viewpoint along Highway 49/88. Andrew Kennedy had explored the area up to the Oneida Mine boundary line to the North. He is also credited with digging a prospecting shaft to a depth of 100 feet, using a bucket attached to a winch with a handle. This shaft was sunk approximately 400 feet south of the Oneida boundary line beginning perhaps as early as 1855. Andrew’s three partners were associated with the Oneida Mine at the time the mining claims were filed.

The Formation of the Kennedy Mining Company

The Kennedy Mine, Jackson CA Andrew sold his one quarter interest in the undeveloped mining claim within a year, on October 4, 1861, for $5,000.00. The four partners operated sporadically along one whim shaft until 1869. The Mine was sold to eleven Jackson businessmen for $1.00 on November 22, 1869. Nine of these men formed a corporation named the “Kennedy Mining Company.”

Peter Reichling, one of the nine corporate members, operated the Mine as superintendent. He operated the Mine periodically for a total of 41 months between 1870 and June 1878. At least three new shafts, which yielded gold, were sunk during this time period. One of these three would later be referred to as the “South Shaft.”

The Kennedy Mining Company is credited with recovering $300,000 in gold value between 1870 and 1878. The amount of gold recovered prior to 1870 by the partnership is unknown, but considered modest compared to the $300,000. Several attempts to reopen the Mine by the Kennedy Mining Company after 1878 were unsuccessful.

The Need for More Capital: Kennedy Mining and Milling Company

The Mine was sold again in 1886 for $97,500 to fifteen Bay Area investors after prominent mining engineer, J.J. Thomas, had performed extensive ground testing. The lead investor was Francis Reichling, the older brother of Peter. The new investors incorporated under the name of the “Kennedy Mining and Milling Company.”

The Kennedy Mining and Milling Company investors were able to infuse more capital into the business. They employed an experienced manager and engineer J. J. Thomas who succeeded in operating the mine profitably,  Some of the major factors that brought about this change in profitability were (1) a larger amount of investment capital by the fifteen investors to purchase up-to-date mining machinery, (2) the implementation of effective mining engineering concepts by J.J. Thomas, (3) the availability of sufficient water from the Sierra to effectively use water power to run the mining machinery, and (4) the discovery of rock at greater depth with a higher quantity of gold.

Word War II and the Closing of the Mines

The Kennedy Mine, Jackson CA The Kennedy Mine operated successfully until the U.S. Government closed all major gold mines in 1942 due to the war effort. The Kennedy was the deepest gold mine in North America when it closed in 1942 at 5,912 vertical feet (meaning as measured straight down below the surface). It had well over 50 miles of underground excavations.

Order L-208 was lifted in 1945, which allowed the gold mines to resume operations. Management at the Kennedy chose not to reopen the Mine because of the extensive water that had accumulated in its numerous deep underground excavations after remaining idle for three years. Gold production of the Kennedy by that time had totaled over $28,000,000.

For a time, during and after WWII, the Anaconda Mining Corporation toyed with purchasing both the Kennedy Mine and the nearby Argonaut Mine, but decided against it. The factors they considered were: the low price of gold, miners were not available after the war, the cost of labor was high, both mines were flooded and would require years to pump out and re-timber, plus maintenance costs. Unfortunately, the costs of re-opening exceeded the expected profit.

The Kennedy Mine Re-Opens as a Historic Site

The property lay idle until Sybil Arata, a ceramics teacher in San Francisco, bought the 154-acre Kennedy Mine at a liquidation sale in 1961 for $41,600.00 and retired to live there.

Sybil lived in the historic Bunkhouse Manager's Residence on the mine grounds for many years. She died on May 12, 1994 leaving a will that stipulated two wishes. (1) The Kennedy Mine property was to remain as open space for wildlife habitat; and (2) the Mine was to be maintained for its historical value.

The Kennedy Mine Foundation was formed in 1996 to fulfill those wishes. Today the mine is open for tours of the historic grounds. School tours, and Special Group tours are available. Experienced guides tell the fascinating story of this historic mine whose operation helped build the State of California.
