A Cu-Pb-Zn-Ag-Au-Mo mining area located in T.20S., R.14E., on the West slope of the Santa Rita Mts, on the drainage of that part of Madera Canyon which is within Santa Cruz Co.

Mineralization is spotty and weak, partially oxidized, base metal sulfides with associated minor gold and silver values, with or without quartz, along shear zones in LAramide intrusives or metamorphosed volcanics.

Workings are scattered, small, and generally shallow operations. Mostly prospects with no recorded production.
