Report issued by the Bureau of Mines regarding studies conducted on zinc-lead mines in Clark County, Nevada. Physical qualities of the mine, equipment used, and methods of sampling are presented. This report includes tables, and maps.

The purpose for agency action is to preclude surface entry and the location of new mining claims, subject to valid existing rights, within and surrounding the Caliente rail corridor as described in the Yucca Mountain FEIS (DOE 2002). This protective measure is needed to enhance the safe, efficient, and uninterrupted evaluation of land areas for potential rail alignments within the Caliente rail corridor. The evaluation will assist the DOE in determining, through the Rail Alignment environmental impact statement (EIS) process, whether to construct a branch rail line, and to provide support to the BLM in deciding whether or not to reserve a ROW for the rail line under the Federal Land Policy and Management Act (FLPMA). The BLM participated as a cooperating agency in preparing this EA because it is the responsible land manager and BLM staff could contribute resource specific expertise.

This is a map of the geology of Jackass Flats quadrangle.

From abstract: This report summarizes the porosity, density, and water content data on about 200 tuff specimens from the Tunnel Beds which compose the lower member of the Oak Spring Formation of Miocene (?) or younger age at the Ul2e tunnel, Rainier Mesa, Nevada Test Site.

From introduction: The pre-shot and postshot mine surveys indicated that no damage attributable to the Shoal event occurred to any of the sixteen private mining properties.

From introduction: This report documents the preshot and postshot condition of all structures within 10 miles of Ground Zero, plus structures at Salt Wells and surface structures at mines that were included in the mine survey.

From introduction: This report is based on the field and laboratory studies of the uranium mineralization in the vicinity of Goodsprings, Clark Co., Nevada. The location of the region is shown in figure 1.

From operational program: This final report includes a general geologic description of the area, including descriptions of the various geologic units and correlates the airborne data to the geologic units as provided by the geologic maps. Also included is a frequency distribution study of the data as a function of the geologic units encountered over the NTMS area including the tie line data. This report also consists of a discussion of the area surveyed and includes all single record reduced data and averaged record data listings on microfiche.

Abstract: This report presents the results of the Roach Lake Basin, Nevada, orientation study in the Kingman 10 x 2* quadrangle of the National Topographic Map Series (NTMS). Wet, dry, and playa sediment samples were collected throughout the 420 km2 semi-arid, closed basin. Water samples were collected at the few available wells and springs. In addition to neutron activation analysis for uranium and 15 to 20 trace elements on all samples, field and laboratory measurements were made on water samples. Analytical data and field measurements are presented in tabular hardcopy and fiche format. Four full-size overlays for use with the Kingman NTMS 1:250,000 quadrangle are included. Water sample site locations, water sample uranium concentration, sediment sample site locations, and sediment sample total uranium concentration are shown on the separate overlays. A general description of the area and the rock type distribution is presented. Some of the data in this report have been issued previously in "Preliminary Report on the Roach Lake Pilot Study," GJBX-44(76), August 1976.

The following report presents the results of the geochemical reconnaissance sampling in the Millet quadrangle, Nevada.

Report issued by the Bureau of Mines over studies of mercury deposits in Nevada, and Oregon. History, physical features, and geology of the deposits are presented. This report includes maps, and illustrations.

From abstract: Uranium is associated with copper and tin ores in the Majuba Hill area, Antelope mining district, in the central part of the Antelope Range, Pershing County, Nev. About 23, 000 tons of copper and 200 tons of tin ore, a small quantity of lead-silver ore, and some arsenic-silver ore have been produced from the Majuba Hill mine, the Last Chance mine, and a mine in sec. 34, T. 33 N., R. 31 E.

Report discussing the copper and tin ores of the Majuba Hill area of the Antelope mining district that are associated with uranium deposits.

The following report covers the effects of the Rainier, Logan, and Blanca explosions on tuff that were determined through observations and measurements on the surface and in drill holes and tunnels.

The following report summarizes the investigations made following the Mighty Epic event beneath the surface of Rainier Mesa in U12n.10 tunnel at the Nevada Test Site.

This report summarizes the results of the U.S. Geological Survey geophysical and geological studies of the rock in the U16a.04 tunnel in the Nevada Test Site.

A report regarding pegmatites of the Errington-Theil mine, Elko County, Nevada.

From Abstract: "The Oak Ridge National Laboratory (ORNL) Health Physics Research Reactor is to be attached to a hoist platform on a 1500-ft tower at the Nevada Test Site (NTS). The project is a continuation of the studies commenced in 1956 for evaluating the radiation doses of persons exposed to nuclear weapons, especially the residents of Hiroshima and Nagaski, Japan. Measurements will be made of the energy, angular, and spatial distributions of the radiation from the reactor."

Report examining "[t]he effect of ground roughness, or surface irregularities, on the radiation field above ground which had been contaminated with fallout from the explosion in the atmosphere of a nuclear device (Smallboy Event)" (p. v).

Report issued by the U.S. Bureau of Mines discussing safety hazards in western mines. Mine hoisting and haulage accidents are presented. Accident prevention is also discussed. This report includes tables.
