Argonaut Gold Mine

The Argonaut Mine is a gold mine in Jackson, California, United States. It was discovered in 1850 and was the site of the worst gold-mining disaster in the state's history. The mine closed in 1942 and, along with the nearby Kennedy Mine, is registered as California Historical Landmark #786.

It was discovered by two miners, James Hager and William Tudor. The mine's serious development began in 1893 when it was purchased by the Argonaut Mining Company. The mine operated until 1942, reaching a vertical depth of 5,570 feet (1,688 m) via a sixty-three degree shaft and produced more than $25 million in gold.
