From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) McDermitt 1 x 2* quadrangle. Surface sediment samples were collected at 1337 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Ground water samples were collected at 255 sites and surface water samples were collected at 41 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water and surface water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site.

Results of a survey of the Worthington Mountains Wilderness Study Area (NV-040-242) in Lincoln County, Nevada to determine mineral values, if any. The survey determined that metallic mineral (Cu, Pb, Zn, Au, Ag, W) resource potential within the study area is moderate, with level-B certainty, in the northernmost part, and it is low, with level-C certainty, in the remainder of the area. The report outlines the survey measurements and final results, with references and associated resource materials.
From abstract: At the request of the U.S. Bureau of Land Management, approximately 84,165 acres of the Clover Mountains Wilderness Study Area (NV-050-139) was evaluated for mineral resources (known) and mineral resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area;" any reference to the Clover Mountains Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The study area is located in southern Nevada, in Lincoln County, about 90 mi northeast of Las Vegas. No identified mineral resources exist inside the study area, although gold, silver, and copper resources are found immediately to the west at the Pennsylvania mine.
From summary: During 1983 and 1984, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to assess the mineral resource potential and appraise the identified resources of a part of the Far South Egans (NV-040-172) Wilderness Study Area. The area studied encompasses about 63.5 mi2 (square miles) (42,316 acres) in Lincoln and Nye Counties, Nevada, and is in the southern part of the Egan Range of east-central Nevada.
From introduction: This report presents an evaluation of the mineral endowment (identified resources (known) and mineral resource potential (undiscovered)) of the study area and is the product of several separate studies by the USBM and the USGS.
From abstract: The Mount Grafton Wilderness Study Area (NV- 040-169) is in a remote area of the Schell Creek Range, Nevada. In 1984 and 1985 the U.S. Geological Survey and the U.S. Bureau of Mines evaluated the identified mineral resources and mineral resource potential of approximately 30,115 acres of the study area at the request of the U.S. Bureau of Land Management. The study area contains identified low-grade resources of zinc and tungsten. The study area has a low potential for oil and gas, uranium and thorium, and geothermal and clay resources.
From summary: The Parsnip Peak (NV-040-206) Wilderness Study Area in Lincoln County, Nevada, is 10 mi (miles) northeast of the small mining town of Pioche. A mineral resource study of the area was completed in the summers of 1984 and 1985 by the U.S. Geological Survey and U.S. Bureau of Mines. A small area of limestone and dolomite on the western side of the wilderness study area has high mineral resource potential for arsenic, antimony, mercury, and gold. The rest of the Parsnip Peak Wilderness Study Area has low mineral resource potential for metals, oil and gas, coal, and geothermal energy.
From summary: The USGS (U.S. Geological Survey) and the USBM (U.S. Bureau of Mines) studied the mineral resource potential of 50,499 acres of the 61,137-acre Weepah Spring Wilderness Study Area (NV-040-246), Lincoln and Nye Counties, Nev., at the request of the BLM (U.S. Bureau of Land Management). In this report, the area studied is referred to as the "wilderness study area" or the "study area." Field studies of the area were conducted during summer 1984 by USBM geologists and during spring 1984 and fall 1985 by USGS geologists, geochemists, and geophysicists.
