This report presents the results of a mineral survey of the Starvation Point Wilderness Study Area (AZ-010-005/UT-040-057), Mohave County, Arizona and Washington County, Utah.

Abstract: The Fish Springs Range Wilderness Study Area (UT-050-127) includes most of the Fish Springs Range and is located north of the House Range, about 50 miles northwest of the city of Delta, Utah. A mineral resource study of the 33,840-acre area was completed in 1987 by the U.S. Geological Survey and U.S. Bureau of Mines. The northwestern and southeastern parts of the wilderness study area contain inferred subeconomic resources of high-purity quartzite. No metallic mineral resources were identified in the study area, but more than 17 million pounds of lead, 2.6 million ounces of silver, and minor copper, zinc, and gold have been produced from the Fish Springs mining district, which is immediately outside the northwest boundary of the wilderness study area. The potential for undiscovered deposits of these metals and molybdenum is high near the northern end of the study area, adjacent to the mining district, moderate near the southern end, and low in the remainder of the area. The resource potential for undiscovered deposits of high-purity limestone and dolomite is moderate throughout the study area except where quartzite is present; potential for undiscovered low-temperature geothermal resources and for oil and gas is low throughout the study area.

From abstract: The Deep Creek Mountains Wilderness Study Area (UT-020-060/UT-050-020) includes most of the Deep Creek Range of west-central Utah. The area is near the Utah-Nevada State line, south of Wendover, Utah, and northwest of Delta, Utah. Eleven areas of mineralized rock in and near the study area were evaluated by the U.S. Bureau of Mines. Four of these areas contain identified resources: (1) an indicated resource of 5,000 short tons of 16.5 ounces silver per short ton, 4.1 percent lead, 4.6 percent zinc, and 0.25 percent copper, at the Willow Springs area, which is almost surrounded by the study area in the northeast corner although it is not part of the study area; (2) an indicated gold resource of 774,000 short tons of 0.4 ounces per short ton and an inferred gold resource of 5.7 million short tons of 0.4 ounces per short ton in the Goshute Canyon area immediately east of the study area; (3) an indicated gold resource of 75,000 short tons of 0.22 ounces per short ton in the Queen of Sheba mine just west of the study area; and (4) an inferred gold resource of 3,800 short tons of 0.26 ounces per short ton in …

Summary: At the request of the U.S. Bureau of Land Management, two wilderness study areas in southern Utah (fig. 1) were studied in order to appraise their identified mineral resources and assess their potential mineral resources. The areas studied are the Cockscomb (UT-040-275) Wilderness Study Area, 5,100 acres (8 square miles), and the Wahweap (UT-040-248) Wilderness Study Area, 70,380 acres (110 square miles), both in Kane County, Utah. In this report the areas studied are called "wilderness study areas," simply "study areas," or "Cockscomb area" or "Wahweap area," as appropriate. The Cockscomb area (fig. 1) lies along the steeply east-dipping East Kaibab monocline, and the Wahweap area, farther to the east, consists of flat-lying but gently folded rocks. These areas adjoin the Paria-Hackberry Wilderness Study Area (UT-040-247) to the west.

From abstract: The Paria-Hackberry Wilderness Study Area, in central Kane County, southern Utah, is a region of generally flat-lying, gently folded sedimentary rocks, bounded on the east by the east-dipping limb of the East Kaibab monocline and cut by sheer-walled, narrow canyons. The area selected for study by the U.S. Bureau of Land Management totaled 94,642 acres (148 square miles); because of uncertainty as to final boundaries, the U.S. Geological Survey studied an additional contiguous 41,180 acres (64 square miles).
