A small surface and underground Cu prospect with underground workings located in the NE ¼ sec. 6, T.16S., R.23E. (Dragoon 7.5 minute topo map), 3.5 miles north of Dragoon, and 2.5 miles SE of Johnson. Owned by Mrs. Thomas Adams of Dragoon, AZ (1955-).
Mineralization consists of seams and pockets of chrysocolla in a band of tactite in recrystallized Pennsylvanian-Permian Naco Group limestones (Horquilla Limestone). Alteration includes tactite and recrystallized limestone. An associated rock unit is the Texas Canyon Quartz Monzonite.
Local structures include a "lamprophyre dike," and Tertiary block faulting trending NW. Regionally, Late Cretaceous or Early Tertiary N- and NW-trending folds and thrust faulting are overriding to the NE.
Workings include a shaft(s) and surface workings to 45.72 meters deep and diamond drilling. There has been little or no production.
