The collection comprises the Arizona mineral exploration files (mostly for gold and copper) of Cambior Exploration USA Inc. The collection also includes information from acquired companies Westmont Mining and Nicor Mineral Ventures Inc. It contains exploration data as well as submittal information gathered during the 1980s through 1999. Data was not received for some of the company’s major projects during the period, for example Newsboy and Carlota.

Richard (Dick) Hahman was born in Buffalo, New York, in 1936. He grew up in coal mining towns in Pennsylvania, then later in Washington, D.C. He received his master's in geology from the University of West Virginia. His career took him through the U.S., Canada, Mexico, and Chile. He worked for several companies in Tucson, Arizona, before going to work for Conoco Inc. in Oklahoma City in the early 1980s. In the late '80s he started his consulting company, Hahman & Associates, in Las Cruces, New Mexico. He moved back to Tucson around 1997. The collection contains geologic reports, drill logs, maps, assays, photos and field notes from exploration in Arizona and New Mexico.

Earl Edward Brabb spent his 40-year career with the U.S.Geological Survey carrying out a number of scientific investigations with a focus on natural hazards. He is the author or co-author of more than 170 maps and reports. During his career with USGS, Earl E. Brabb produced multiple fieldbooks dating back to 1957. His fieldbooks are currently being scanned and converted to PDFs.

Boxes and maps of uranium exploration data were donated to the CGS several years ago referred to as the “Tallahassee Creek data.” This exploration data set focuses on the Hansen/Taylor, Picnic Tree, and High Park uranium deposits in the Tallahassee Creek mining area. These uranium deposits, a critical mineral as defined by Fortier and others (2018), occur in the Eocene Echo Park Alluvium and Oligocene Tallahassee Creek Conglomerate. Between 1957 and 1972, 95,400 tons of ore averaging 0.25% triuranium octoxide (U3O8) were mined in this area mostly from the Tallahassee Creek Conglomerate (Chenoweth, 1980). Exploration companies report Hansen/Taylor deposit resources of 29,730,000 tons grading at 0.063% U3O8 containing...
Location data for exploratory, sciencific, or engineering borings conducted statwide since the early 1900s. Drill Core and/or other samples from a large number of these borings are stored in the DNR's Drill Core Library in Hibbing, Minnesota. For more information on the drill core library please vist the DNR's webpage: http://www.dnr.state.mn.us/lands_minerals/dc_library.html

The Minnesota Department of Natural Resources (DNR) completed an inventory of the holdings of the DNR Drill Core Library (DCL). The Drill Core Library facility contains geologic materials including drill core, rotasonic samples, cuttings, pulps and rejects, processed materials, peat, thin sections, thin section billets and hand samples. The inventory project also included identifying space and preservation issues, beginning the process of centralizing and standardizing the administrative databases for all holdings, and making more information within the DCL publicly available.

The Lynne Deposit is a Volcanogenic Massive Sulfide Deposit in Oneida County in northern Wisconsin containing zinc, lead, silver, and small amounts of gold and copper. In 1990 and 1991, the Noranda Company drilled 133 exploration boreholes, and the core from some of these holes was donated to WGNHS and the Natural Resource Research Institute (NRRI) in Duluth, MN. In 2021, the NRRI donated core from seven holes to WGNHS. These cores were photographed, and detailed logs were created by Dr. Robert Lodge and students from the University of Wisconsin Eau Claire. Original documentation from the Noranda Company including logs, assays, cross sections, reports, and a site map are available at Oneida County’s website: https://www.co.oneida.wi.us/archive/mining/category1da1.html?linkcatid=9...
Most projects conducted by the MWRA have attached to them a geotechnical report and accompanying environmental information. There are also eighteen marine drilling reports on work in the Boston Harbor, as well as, two hardbound copies on the Geology of the Waschusett Reservoir Area. All reports are stored in the library at the main facility in Chelsea; however, not all project managers turn over reports to the librarian for storage. Most projects conducted by the MWRA, related to the construction of water and sewer lines, have attached with them, a geotechnical report and accompanying environmental information. Other paper reports include: eighteen marine drilling reports from work in Boston Harbor; as well as two...

This is a collection of rock cores, which are whole or slabbed, housed in the Bureau of Economic Geology’s Core Research Centers.
This is a collection of thin sections, primarily from rock cores, housed in the Bureau of Economic Geology’s Core Research Centers.
Authorized by Congress in 1879, the US Geological Survey (USGS) Library is recognized as one of the world’s largest Earth and natural science libraries, providing services, collections, and expertise that are essential to the USGS mission and the global geoscience community. The USGS Library is a multisite, centralized library, providing bureau-wide access to scholarly journals and research support services to USGS employees around the nation. An important role of the USGS Library is the preservation of its unique physical collections, ensuring continued access for future generations.

Poorly-labeled boxes of rock, sediment, and fossil specimens collected by individual workers at different times. Also, numerous samples of Cenozoic volcanic ashes that may be of unrealized future value as a reference collection. Hand specimens exist in our collections, but they are completely uncataloged and are improperly stored. This collection may be discarded as additional space restrictions are imposed.

The 3002’ length core was extracted from the Redstone Quarry in Conway, NH in 1975 as part of an evaluation of geothermal potential produced by the natural decay of several radioactive minerals present in the Jurassic age Conway Granite pluton. The core extracted from the borehole at the Redstone Quarry is the deepest core drilled in New Hampshire. The Redstone Core project was part of a collaboration between the New Hampshire State Geologist and the U.S. Energy Research and Development Administration. Significant geothermal resources were not found. NHGS estimates that approximately half of the original 3002’ foot core remains in core boxes with sufficient documentation tags to identify the depth intervals each...
