Ref: Located in 1878 and mined for gold-bearing quartz. Operated by shaft and whim feeding a single-stamp mill until 1884, when a 25-stamp mill was completed. Expanded again in 1885 with an additional 60-stamp mill.
Temporarily closed in 1886 due to investor financial difficulties.
By 1888, the large volume of ground water required installation of a 1,500 gallon per minute Cornish Pump. However, the mine closed in 1890 due to excessive water. Production from 1878 to 1888 estimated 100,000 tons of ore and 20,000 ounces of gold.
Reopened in 1894 under lease. An additional two Prescott pumps were installed to handle ground water. The shaft was enlarged to three compartments in 1899, reaching depths of 500 feet by 1901 and 700 feet by 1903 with plans to attain 1000 feet.
On June 5, 1905, a collapse "dammed" ground water and the pumps ran dry. While attempting to repair them, the "dam" broke and mine flooded.
Homestake Mining Company obtained a 2-year lease in 1924, but discontinued diamond drilling the same year. Anaconda Mining Company leased the property in 1934. By 1936, they had dewatered the mine, repaired the mill and produced 6,000 tons of ore from the 700 foot level, yielding 274 ounces of gold. The mine was closed in 1937 due to high costs.
