A former underground Au-Ag-Cu mine located about 2 miles East of the Tiger Mine, on the south slope of the Bradshaw Mountains at 5,400 feet of altitude. It was started before 1900 and closed in 1912. Reopened 1915-1916. Owned by F.E. Harrington (1900-1912); and, Mrs. Hattie Barnes of New York (1926). Claims extend into the E½W½NE¼ and the N½N½SE¼ of sec. 34, and the S½SE¼SE¼ of sec. 27, and the SW¼SW¼SW¼ of sec. 29, and the NW¼NW¼NW¼ of sec. 35.
Mineralization is the Oro Belle vein, which is small and was worked through 8 tunnels. This vein is in highly metamorphosed, in large part sedimentary, schist. In places intruded by fine-grained granite dikes. The vein is said to be small. Associated rock units include the Crazy Basin Quartz Monzonite (1.5 miles east of the mine) and rhyolite dikes. Ore control was faulting. No alteration noted.
Workings include 8 tunnels the longest of which is 1,000 feet long. Produced an estimated $700,000 of metal (period values)(with the Gray Eagle Mine).
