The mine was located 3 miles north of Plymouth. The mine was originally developed through a 422 foot crosscut adit from which some ore was produced prior to 1900.
Little mining was done thereafter until 1917 when a 580 foot vertical shaft was suck approximately 700 feet southwest of the adit portal, Earnest A. Stent continued intermittent development work through the 1920's.
More development work by the Amador Star Mining Company was done on the 300 foot level in 1931.
