A Pb-Ag-Zn-Cu-Au mine group located in the SW ¼ sec. 26 & the SE ¼ sec. 27, T.17S., R.10E. Owned at times, or in part, by the Lincoln Consolidated Mining Co.; Silverta Mining & Milling Co.; and the Yellow Bird Silver Mines.

Mineralization is oxidized, argentiferous galena and sphalerite with minor copper in spotty replacement bodies in metamorphosed Paleozoic limestone; and argentiferous chalcocite, copper carbonates and oxides in shattered Paleozoic quartzite. Paleozoic beds infolded in mesozoic sediments and volcanics.

Workings include shaft, tunnels, and open cuts. Prospected and worked in the late 1800's for high-grade Pb-Ag ore and sporadically from 1905 to 1919, producing some 65 tons of ore at 14% Cu, 12 oz. Ag/T and minor gold.
