A Pb-Ag-Mn-Cu-Au-Mo mine located in the SE ¼ sec. 26, T.17S., R.10E. Owned by the Aguinaldo Mining Co.
Mineralization is veins and replacement lenses of oxidized manganese and sulfides, and wulfenite, in fractured and metamorphosed Paleozoic limestone.
Working include adits, shafts, and open cuts. Originally worked for silver prior to 1900, with minor, sporadic, subsequent production. Probably not more than 100 tons of high-grade Pb-Ag ore were produced, plus some Cu and hand-picked wulfenite.
