A gold mine located on the east side of Eureka gulch north of Republic. This was one of the first claims staked after the noth half of the county was opened for mining. It worked a vein of chalcedonic quartz 7-8'wide cuts porphyritic andesite Development includes a 400' shaft with several drifts and stopes, with a winze sunk from the 400' to 500' level. It produced a total $720,938.70 up to 1920, 1936, 22,402 tons in 1937, 9.828 tons in 1938, 1939-1940. Total production is 161,000 tons at 0.38 oz/ton gold and 2.50 oz/ton silver.
Tectonics: Epithermal Deposits Of The Republic District Are Found In The Eocene Sanpoil Volcanics. (See Republic District For Additional Details.)

Deposit: Host rocks for gold deposits of the republic district are dacite and andesite flows, flow breccias, tuffs, and tuff breccias of the eocene sanpoil volcanics (muessig, 1967, p. 50-51; tschauder, 1989, p. 242). ; info.src : 1 pub lit

Development: ECON.COM: TOTAL PRODUCTION OF $720,938.70 WORTH OF ORE TO THE END OF 1920; PRODUCED IN 1936, 1937 (22,402 TONS), 1938 (9828 TONS), AND IN 1939-1940 (HUNTTING, 1956, P. 123).

Ore(s): The Vein Of Chalcedonic Banded Quartz Is 7-8 Ft. Wide And Cut Propylitic Andesite (Huntting, 1956, P. 123). (See Republic District For Additional Details.)
