Mineral resources of the Whipple Mountains and Whipple Mountains Addition Wilderness Study Areas, San Bernardino County, California

At the request of the U.S. Bureau of Land Management, approximately 85,100 acres of the Whipple Mountains Wilderness Study Area (CDCA-312) and 1,380 acres of the Whipple Mountains Addition Wilderness Study Area (AZ-050-010) were evaluated for identified mineral resources (known) and mineral resource potential (undiscovered). In this report, the Whipple Mountains and Whipple Mountains Addition Wilderness Study Areas are referred to as simply "the study area." Most of the mines and prospects with identified resources in the Whipple Mountains Wilderness Study Area are within areas designated as having mineral resource potential. The area in and around the Turk Silver mine and the Lucky Green group and the area near the northwest boundary of the study area have high mineral resource potential for copper, lead, zinc, gold, and silver. An area along the west boundary of the study area has moderate resource potential for copper lead, zinc, gold, and silver. An area in the east adjacent to the Whipple Mountains Addition Wilderness Study Area has moderate resource potential for copper, gold, and silver resources. One area on the north boundary and one on the southeast boundary of the study area have low mineral resource potential for copper, lead, zinc, gold, and silver. Two areas, one on the north boundary and one inside the east boundary of the study area, have moderate resource potential for manganese. A small area inside the south boundary of the study area has high resource potential for decorative building stone, and the entire study area has low resource potential for sand and gravel and other rock products suitable for construction. Two areas in the eastern part of the study area have low resource potential for uranium. There is no resource potential for oil and gas or geothermal resources in the Whipple Mountains Wilderness Study Area. Sites within the Whipple Mountains Wilderness Study Area with identified resources of copper, gold, silver, manganese and (or) decorative building stone are located at the Stewart mine, New American Eagle mine, Turk Silver mine, Twin Lode mine, decorative stone property, Lucky Green group, Blue Cloud mine, Nickel Plate mine, Crescent mine, Quadrangle Copper group, and the Copper Basin mine. The Whipple Mountains Addition Wilderness Study Area has moderate resource potential for copper, gold, and silver resources and low resource potential for sand and gravel and other rock products. There is no resource potential for oil and gas or for geothermal energy in the Whipple Mountains Addition Wilderness Study Area. Although there are no identified resources in the Whipple Mountains Addition Wilderness Study Area, sites within and immediately adjacent warrant further study because of gold assays from widespread, numerous samples.

Mineral resource potential map of the Great Rift Instant Study Area, Blaine, Butte, Minidoka, and Power counties, Idaho

A high potential exists for development of decorative building stone resources from slabby, glassy-surfaced pahoehoe lava flows, particularly in the Wapi lava field where the largest volume and variety of stone occurs. The unique appearance of the Blue Dragon flow material from the Craters of the Moon lava field may enhance its potential as a decorative stone resource. Locating speculative resources (uraniferous sediment, auriferous gravel, and geothermal reservoirs) and hypothetical resources (oil and gas) that may underlie the geologically young lava flows of the study area would require extensive geophysical exploration and drilling.

Reconnaissance geologic map and mineral resource potential of the Gearhart Mountain Wilderness and Roadless Area (6225), Lake and Klamath counties, Oregon

The Gearhart Mountain Wilderness, Lake and Klamath Counties, Oreg., is devoid of mines and mineral prospects and there are no known mining claims within the area. Furthermore, the results of this mineral appraisal indicate that there is little likelihood that commercial deposits of metallic minerals will be found in the area. Commercial uranium deposits, like those at the White King and Lucky Lass mines about 16 mi (~25 km) to the southeast of the wilderness, and deposits of mercury, like those south-southeast of the wilderness, are not likely to be found within the wilderness, even though all of these areas are characterized by middle and late Cenozoic intrusive and extrusive volcanic rocks. Rock of low commercial value for construction purposes is present, but better and more accessible deposits are present in adjacent regions. There is no evidence to indicate that mineral fuels are present in the area. Higher than normal heat floe characterizes the region containing Gerheart Mountain, indicating that it may have some, as yet undefined, potential for the development of geothermal energy. Data are not available to determine whether this higher than normal heat flow is meaningful in terms of a potential energy source or as a guide to possible future exploration; lack of thermal springs or other evidence of localized geothermal anomalies within the Gerhart Mountain suggest, however, that the potential for the development of geothermal energy is probably low.

Mineral resource potential of the Centennial Mountains Wilderness Study Area and contiguous areas, Idaho and Montana

The Centennial Mountains include parts of Beaverhead County, Montana, and Clark and Fremont Counties, Idaho; the mountains trend east, and the Continental Divide follows their crest (fig. 1). They form a massive, almost impassable barrier between Centennial Valley on the north and the broad expanse of the Snake River Plain on the south. The proposed Wilderness Study Area encompasses the central more rugged part of the mountains and includes parts of both the Targhee and Beaverhead National Forests. Four contiguous parcels of land, totaling about 96,176 acres (38,922 hectares), make up the Wilderness Study Area (fig. 2). The first of these, encompassing about 46,126 acres (18,667 ha), is wholly in Montana (north of the Continental Divide) and consists of the U.S. Bureau of Land Mapagement's Centennial Mountains Instant Study Area. The second area, known as Management Unit 1 of the Centennial Planning Unit of the Targhee National Forest, consists of some 38,750 acres (15,682 ha) within Idaho (south of the Continental Divide). The third and fourth parcels include about 11,300 acres (4,573 ha) of National Forest land which cover the Mt. Jefferson and Sawtell Peak areas in the eastern part of the Centennial Mountains. Both are Forest Service Further Planning roadless areas (Unit 1-962 of the Beaverhead National Forest in Montana—the Mt. Jefferson area, and Unit 4-962 of the Targhee National Forest in Idaho—the Mt. Jefferson West area). Details of the geography and geology of the area are incorporated in a separate map prepared as an integral part of the mineral resource evaluation (Witkind, 1981). Only the more salient details of the geology described in that report are repeated here.

Mineral resources of the Sheep Mountain Wilderness study area and the Cucamonga Wilderness and additions, Los Angeles and San Bernardino counties, California

A mineral survey of the Sheep Mountain Wilderness study area and Cucamonga Wilderness area and additions by the U.S. Geological Survey and Bureau of Mines in 1975 covered about 66,500 acres (26,500 ha) of the San Bernardino and Angeles National Forests in southern California. The two study areas are separated by San Antonio Canyon. The mineral resource potential was evaluated through geological, geochemical, and geophysical studies by the Geological Survey and through evaluation of mines and prospects by the Bureau of Mines.
