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.
