From abstract: A small quantity of uranium ore was shipped from the White Oak No. 1 mine, Pajarito mining district, Santa Cruz County, Ariz., in 1952. The uranium is associated with oxidized lead ore in a shear zone that cuts rhyolite 'porphyry of Tertiary(?) age. The uranium minerals -- kasolite, uranophane, dumontite, autunite, and possibly radioactive pyromorphite -- are concentrated along small, discontinuous fractures, and accordingly the ore bodies are small and widely dispersed.

Abstract: Reconnaissance mapping in the Ruby Quadrangle, Arizona, indicates the existence of a complex assemblage of volcanic rocks and associated sediments, divisible into a younger and older series.

A total of five hot springs and 25 thermal wells are located within the combined counties. The water discharged from these hot springs and wells may be suitable for applications such as process heat and space heating and cooling. Within Cochise county there are two large firms which are capable of using 70/sup 0/C (158/sup 0/F) geothermal water for their process heat requirements but the potential use of geothermal energy in Santa Cruz county is limited due to the absence of industry within the county. The amount of geothermal energy on line as a function of time under both private and city-owned utility development is also predicted using a computer simulation model.

From introduction: The Annie Laurie 'cranium Prospect, in the Oro Blanco district of southern Arizona, is located in the southwest quarter of Sect. 3, T233, R=13. The nearest United States post office is Nogales, about 25 miles east, and the nearest settlement is Ruby, a nearly abandoned mining camp about 3 miles north. Access to the Ruby area is by gravel road from US highway 39 at Kinsley or Nogales. The Ruby quadrangle (1940) includes the area surrounding the prospect.
