Deposits located in Powers Gulch, near the SW corner of the Inspiration quadrangle.

Mineralization is several small Zn-Pb veins that crop out in a diabase sill intruded between Pinal schist and Pioneer formation. They are along fissures or faults of very slight displacement that strike N.30º-60ºE., and dip nearly vertical. Some of the vein fissures can be traced for 1,000 feet or more by the zone of dark chloritic alteration of the diabase, but only short intervals or shoots, generally less than 200 feet long, contain appreciable amounts of ore minerals that range from a few inches to a foot in width. In some places, the shoots comprise several generally discontinuous and lenticular stringers of vein matter that form lodes as much as 4 feet wide.

The veins formed by replacement of diabase wall rock, fault breccia and gouge. The vein matter consists of quartz, sphalerite, galena, a little chalcopyrite, and altered diabase.

Workings are shallow openings.
Mineralization is two small Zn-bearing veins. Explored superficially. One is well-mineralized where crossed by the gulch.
