Wilderness areas; Land use. 46 CO-050-141 R 9 E N R 10E RUE MAP III-7 SAN LUIS HILLS WSA X ;. iREsvft S>4fffr>. !^ Mili-s SAN LUIS HILLS (141) This unit contains 10, 240 acres of land located approximately 3 miles southeast of Manassa. The WSA lies within T. 33 N.. R. 10 and 11 E., T. 34 N., R. 10 and 11 E., NMPM. (See Map III-7.) Air This unit is considered Class II by Federal Air Quality Standards* Geology and Minerals This unit is located at the confluence of two major structural trends. Ore deposits are commonly localized at such trend intersections. The structural trends involved are the Rio Grande rift and the San Juan volcanic field. The King Turquoise Mine, an intrusive center northeast of the unit, is surrounded by advanced argillic alteration. This type of alteration, apparently extending into the WSA, is often associated with base and precious metal deposits. The unit contains felsic intrusive bodies which may be related to the alteration zone. Further exploration and examination are required. Although alteration characteristics show some province for deposition of base and precious metals, a reconnaisance geologic investigation provided no evidence of mineralization. The WSA has very limited potential for mineral exploration or development with the exception of small isolated areas. As of December 31, 1981, there were 85 existing mining claims. There are 9, 600 acres of subsurface minerals in Federal ownership and 640 in non-Federal. Critical Mineral Resource Values The only critical mineral available in the area is concentrations of copper are related to the alteration zone. resource potentially copper. Anomalous reportedly present. Energy Minerals Although this area has not been classified by the USGS as a geothermal area, it is approximately 12 miles from the former Alamosa prospectively valuable area. It is less than 6 miles from reported hot springs and is within the Rio Grande rift zone which
