Locality type:
Group of Claims
Köppen climate type:
A Cu-Au group of several claims located in North-central sec. 15, T1N, R16W, in the area around the head of Cemitosa Wash, along the West base of mesas north of a low divide, in the northern Kofa Mts (S.H. Mountains).
Mineralization is generally weak and spotty, oxidized copper mineralization in small, irregular veins and seams along shear or fault zones in andesite porphyry or closely associated granitic intrusive, along a major northwest-striking structural zone. Basic dike rock is highly altered with numerous slip planes exposed in the workings.
Workings include shallow holes or short drifts.
