Abstract: The Wilson Creek Area, in northern Gila Cointy, is about 10 miles southeast of Young, Arizona, along the east side of Cherry Creek. Four claims covering concentrations of uranium mineralization in the Dripping Spring Formation are owned by the American Asbestos Cement Company. The claims are located in typical plateau-type topography, with flat mesa* and nearly vertical canyon walls. The bedded zones of uranium mineralization are exposed in the Dripping Spring Quartzite near the bottom of the canyons. It is suggested that the mineralized beds may have spatial relationship to the bottom of the Mescal limestone and to the bottom of a thick zone in the upper member of the quart site. Two of the four bedded deposits occur in *crackled" beds. One mineralized fracture was noted. The uranium mineral, meta-torbernite, has formed in tiny vugs in the quart site and is also intergrown with the iron oxide coating on the quart site surfaces. Associated minerals are minor and consist of chalcopyrite magnetite and chalcocite.

Abstract: The discovery and exploration of primary uranium mineralization in the Sierra Anchas of east-central Arizona made possible an analysis of the structural ore controls.
