A former surface W-Au-Pb mine located in the NE¼ sec. 1, T2S, R17W, on federal land. Owned/operated at times, or in part, by Findley and Gibson.
Mineralization is sparse, lensing pockets of scheelite in parallel, discontinuous iron- and manganese-stained quartz lenses in fractured and fissured Mesozoic schist intruded by monzonite porphyry and pegmatite dikes. There is sparse gold in some quartz and minor phosphorous and lead in concentrates.
Workings are shallow surface openings. This site was originally prospected for gold, and later tungsten. It produced some 40 short ton units of WO3 from picked 1% WO3 ore.
