A small former underground Pb-Ag-Zn-Mo-Fe-V-Fluorspar-Baryte-Sr-Cu mine located in the center of sec. 1, T4S, R23W, just E of the Princess Mine, on BLM-administered land. Owned at time, or in part, by Jones; and the Geronimo Mining Co. Owned by Mr. S.P. Huss (1933).
Mineralization is narrow, pockety, quartz-fluorite veins with irregular masses of iron oxide, residual galena, and lead sulfate, carbonate, and oxide, in a 100 foot wide brecciated fault zone in silicified and carbonatized contact metamorphosed Tertiary volcanics. It is variously reported as in the Granite or in a brecciated zone in the andesite.
Workings include a few short tunnels and shaft operations. Probably found early but not worked extensively. Produced some 50 tons of ore in 1923 and 1948 averaging about 27% Pb, 9 oz. Ag/T and minor Au.
12 valid minerals.

|Tithonian - Toarcian|
145 - 182.7 Ma
|Jurassic granitic rocks|
Age: Jurassic (145 - 182.7 Ma)
Description: Granite to diorite, locally foliated and locally alkalic; includes Triassic(?) granitoids in the Trigo Mountains. This unit includes two dominant assemblages of igneous rocks. The Kitt Peak-Trigo Peaks superunit includes, from oldest to youngest: dark, foliated or gneissic diorite, medium-grained equigranular to porphyritic granodiorite, and small, irregular intrusions of light-colored, fine-grained granite. The Ko Vaya superunit, limited to south-central Arizona, includes texturally heterogeneous K-feldspar-rich granitic rocks. (150-180 Ma)
