‡Ref.: Jones, E.L., Jr. & F.L. Ransome (1920), Deposits of manganese ore in Arizona, USGS Bull. 710-D: 157-158.
A group of 4 manganese claims that adjoin the Verdun group on the east. Owned by Frank Tursick, Jack H. Smith, Frank Seibert, R.E. Donaldson, and S.A. Brown, of Needles, California.
This group of claims lies across a reentrant mesa between the volcanic hills and includes a knoll at its east end.
The only deposit discovered is a zone of brecciation that crosses the knoll, strikes east, and is apparently the continuation of the zone on the Verdun group, as it is aligned with that zone. The deposit is contained in rhyolite breccia several feet wide, but the limits of the zone are poorly defined. Psilomelane is the dominant manganese oxide, and it cements fragments of the breccia together and traverses the fractured rock in small, irregular seams. Small masses of the breccia consist of fine fragments of rhyolite a quarter of an inch or less in diameter (0.62 cm or less), cemented together with psilomelane. Calcite accompanies the manganese oxides and partly fills the interstices as a thin coating on psilomelane.
Workings include a few shallow discovery holes.
