A group of former surface and underground Pb-Baryte-Fluorspar-Cu-W-Zn-Mn-V-Ag-Mo mines/prospects located about 2 miles E of the Red Cloud Mine. Owned by the Neal Mining Co. (1933).

Mineralization is veins occurring along fault zones with irregular ore bodies. The veins are banded and up to ¼ inch wide with finely crystalline quartz and fluorite cut by bladed crystals of baryte and veinlets of calcite. Alteration is on the hanging wall, which is chloritized for several feet.

Rocks locally have been extensively faulted and fractured. The major faults strike northward and northwestward. Minor faults strike in other directions. The principal joining in the granite strikes S70W and dips steeply SE.

This property has been prospected by several shallow workings and a short tunnel. No production record.
