The Golden Eagle Deposit is located in Ferry County,Washington, 3 miles north
of the small town of Republic. The deposit is on the northern end of the Eureka Mining
District, which supported underground and open pit mining from 1896 to 1994. The
district has produced over 3 million ounces of gold, primarily from underground mining
at Republic, Knob Hill, and Golden Promise. Additional production came from
small open pit operations at Mud Lake, Mountain Lion, and Trevitt-Pierce, all of
which are on or proximal to Golden Eagle. Historic production focused on gold-silver
bearing quartz veins that cut Sanpoil volcanics.
