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: During the spring and fall of 1979 the U.S. Bureau of Mines made a mineral investigation of the North End Roadless Area, including a literature search, a search of claim records in the Cochise County courthouse and the State office of the Bureau of Land Management, a search for mining claims and mineralized zones, and examination of known mines and prospects. Local residents and officials of mining companies the U.S. Forest Service, and Arizona State government agencies provided information regarding mining activity and mineral deposits.

From summary: In January-April 1984, the Bureau of Mines conducted a mineral survey of the Lower Burro Creek Wilderness Study Area as required by Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976). The Lower Burro Creek Wilderness Study Area comprises 21,700 acres in southeastern Mohave and Yavapai Counties, Arizona. Mines and prospects are located on deposits and (or) occurrences of gold, bentonite, magnesite, and agate in the eastern and southeastern part of the study area.
