Other/historical names associated with this locality:
Riho vein; Ronaldo Pacheco's Mine; Pacheco property
A vein located south of the Papago Mine. Held by the Red Cloud Mining and Milling Co. (1951).
A Pb-Zn-Baryte occurrence located 1¼ miles S of the Papago Mine. Operated by the Red Cloud Mining and Milling Co. (1951).
Mineralization is a vein deposit with a linear ore body.
The prevailing rock is deformed schist with foliation N20E and faulting N50W, 78NE, intruded by dikes of acidic to basic composition and invaded on the west by granite.
On the south claim, the vein strikes N.30º to 40ºW. and dips almost vertically. Northward it pinches out and branches but is traceable intermittently into the north claim where it strikes N.15ºW. and dips 45º to 60ºE.
The vein material consists largely of calcite and white quartz, together with a little barite and nodular masses of cerussite and galena. The calcite is mainly massive and white, but in part gray and manganiferous. The quartz is fine-grained and banded to vuggy. In places the vein shows iron and copper stains. The vein gterminates at a deeply NE-ward dipping fault that strikes N65W.
Workings on the south claim include several pits, open cuts, shafts and stopes. Apparently the shafts do not exceed 50 feet in depth, and the visible stopes are 2 to 4 feet wide.
At the north claim the vein has been stoped from several adits throughout a vertical range of approximately 75 feet on the north side of a deep, narrow ravine. The stopes along outcrop are 2 to 4 feet wide.
