Fluorspar Deposits in Western Kentucky: Part 1
From introduction: The need for fluorspar in the manufacture of open-hearth steel, hydrofluoric acid, aluminum, certain insecticides, refrigerants and airconditioning compounds, welding rods, 100-octane gasoline, and many other products necessary to the prosecution of World War II resulted in unprecedented demands for this commodity. To help increase production to meet these demands, the War Production Board in 1942 asked the United States Geological Survey to plan a comprehensive study of the fluorspar deposits in the United States. This study has been carried on in many parts of the country in cooperation with geologists and engineers of State and Federal agencies and with local producers.

Proposed Exploration for Uranium in the Front Range Mineral Belt, Colorado
From abstract: Recorded production of pitchblende in the United States totals 313 tons of ore containing about 15 percent uranium. Of this total, 303 tons was produced at Central City and 8 tons at Lawson prior to World War I. The remaining 2 tons has been mined at Caribou during the past two years and is being stockpiled at the mine.

Gypsum Deposits near Iyoukeen Cove, Chicagof Island, Southeastern Alaska
From abstract: Two deposits of high-grade gypsum are located near tidewater at Iyoukeen Cove, on the northeastern part of Chichagof Island, southeastern Alaska. A group of claims, formerly operated by the Pacific Coast Gypsum Co., was acquired by the Kaiser Gypsum Division of Kaiser Industries, Inc., during World War II. Claims at the other deposit are held by Dave Housel of Juneau and Seattle, Washington, in the name of the Gypsum-Camel group.

Geology and Fluorspar Deposits, Northgate District, Colorado
From abstract: The fluorspar deposits in the Northgate district, Jackson County, Colo., are among the largest in Western United States. The mines were operated intermittently during the 1920's and again during World War II, but production during these early periods of operation was not large. Mining was begun on a larger scale in 1951, and the district has assumed a prominent position among the fluorspar producers in the United States. Within the Northgate district, Precambrian metamorphic and igneous rocks crop out largely in the Medicine Bow Mountains, and later sedimentary rocks underlie North Park and fill old stream valleys in the mountains.

Structure and Oil and Gas Resources of the Osage Reservation, Oklahoma
From Introduction: "Responding to the imperative need for increasing to the utmost the petroleum supply of the United States, the Geological Survey, since we entered the war, has largely concentrated its investigations of oil fields in the most promising undeveloped territory, such as Wyoming and the midcontinent-Texas region, and especially in the Osage Reservation in Oklahoma. This report is therefore issued to supply an evident need for geologic information regarding the Osage lands. In the separate papers the most practical and immediately available conclusions reached by geologists as to the structure and oil prospects in the townships already examined are published for the immediate use of the oil man."

The Climax Molybdenum Deposit, Colorado
From abstract: The largest single metal-mining operation in the history of mining in Colorado has been developed at Climax, as a result of the increased use of molybdenum in the steel and other industries. Production of molybdenum at Climax was notable for a short period during the World War; it ceased from April 1919 to August 1924 but since then has shown a steady increase. In 1930 from 1,000 to 1,200 tons of ore was milled daily, using only one unit of the 2,000-ton mill. The mine has a reserve of broken ore sufficient to furnish 2,000 tons daily for 3 years and is being developed to continue to furnish this and a still further increased output as the use of the metal may warrant.

Strategic Graphite, A Survey
From abstract: Strategic graphite consists of certain grades of lump and flake graphite for which the United States is largely or entirely dependent on sources abroad. Lump graphite of high purity, necessary in the manufacture of carbon brushes, is imported from Ceylon, where it occurs in vein deposits. Flake graphite, obtained from deposits consisting of graphite disseminated in schists and other metamorphic rocks, is an essential ingredient of crucibles used in the nonferrous metal industries and in the manufacture of lubricants and packings. High-quality flake graphite for these uses has been obtained mostly from Madagascar since World War I. Some flake graphite of strategic grade has been produced, however, from deposits in Texas, Alabama, and Pennsylvania. The development of the carbon-bonded crucible, which does not require coarse flake, should lessen the competitive advantage of the Madagascar producers of crucible flake.

Manganese Deposits of the Talamantes District Near Parral, Chihuahua, Mexico
From abstract: The Talamantes district, 20 kilometers east of Parral in southern Chihuahua, has been the second largest producer of manganese ore in Mexico. Production, which started during World War I and has been more or less continuous since 1930, has totaled about 50,000 tons of ore with an average manganese content of 40 or 41 percent. The mines are on the Mesa de Talamantes, which is underlain by folded Cretaceous (?) limestone, overlain unconformably by gently dipping Tertiary rhyolite flows and tuff, volcanic breccia, agglomerate, and tuffaceous sandstone. Steeply dipping normal faults of northerly trend cut the rock and divide the mesa into a series of blocks.

Mineral Resources of the Wabayuma Peak Wilderness Study Area, Mohave County, Arizona
From abstract: The Wabayuma Peak Wilderness Study Area (AZ-020-037/043), for which a mineral survey was requested by the U.S. Bureau of Land Management, encompasses 40,118 acres in northwestern Arizona. Fieldwork was carried out in 1986-88 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources and assess the mineral resource potential (undiscovered) of the wilderness study area. Within the Wabayuma Peak Wilderness Study Area are 14 private parcels of land totaling 1,315 acres. The Wabayuma Peak Wilderness Study Area, including the 14 private parcels of land, is herein referred to as the "wilderness study area" or the "study area." The Boriana, Antler, and Copper World mines lie near the east boundary of the study area. The Boriana mine was a major tungsten-producing mine of the United States during World War II. The Antler and Copper World mines produced relatively small amounts of copper and zinc prior to 1970.

Mineral Deposits of Central America
From introduction: This report is based on investigations carried on by the Geological Survey (U. S. Department of the Interior) under the auspices of the Interdepartmental Committee on Scientific and Cultural Cooperation (U. S. Department of State) and the Foreign Economic Administration. The function of the last two agencies is presently carried on by the International Cooperation Administration. Roberts is responsible for the text of this report and for the compilation of the geologic map. He was in Central America from January to April 1942 under a program of scientific and technical cooperation with the American Republics sponsored by the Department of State, and mapped manganese deposits in Costa Rica and manganese and antimony deposits in Honduras.
