A former underground Pb-Zn-Ag-Baryte-Fluorspar-Sr-Fe-Mo-V mine located in the center of sec. 1, T4S, R23W (protracted), on BLM-administered land. This mine adjoins the Princess Mine on the South. Started about 1880. Owned at times, or in part, by William W. Blake (1880-1881); Norton, Crawford & Lambie; the Neal Mining Co. (circa 1933), and the New Jersey Zinc Co.

Mineralization is nuggets of argentiferous lead carbonate, sulfate, and oxide intermingled with zinc carbonate and reportedly some galena, argentite, and chlorargyrite, with vanadinite and wulfenite in vugs, in a gangue of calcite and brecciated and silicified wall rock cemented with calcite, barite, celestine, quartz, fluorite, and irregular masses of iron oxide. Irregular fissure filling in a fault zone cutting metamorphic Mesozoic schist intruded by Laramide granodiorite and capped by Tertiary dacite flows and pyroclastics. Vein on surface consists of dark gray, ferruginous calcite up to 8 feet (2.44 meters) thick containing irregular bunches of hematite and coarse-grained, vitreous quartz. This is the same fault zone as the Princess Mine and it strikes NNW, dips 30SW, and curves and is traceable for a mile to the south.

Workings include shaft operations. Worked during the 1880's. No record of production from this mine.

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)
