Mining-Related Property Files and Map Files
This collection includes historical records related to engineering and geologic reports, pictures, correspondence, news clippings, and production information for over 4,700 mining claims, groups of claims, mining projects, deposits, mining districts and/or exploration projects from 51 Montana counties.
The contents of files related to the properties vary. They may include mineral information, production numbers, assays, mine status, claim maps, legal documents, geologic reports, surveys, correspondences, publications, and photographs. Available historic maps also vary, from surface claim boundaries to underground workings and cross sections.
These materials are accessible at our office in Butte, MT. A limited number of files are available for download through our archive search engine . However, a majority of records in the search engine provide a location of the property, but do not have associated downloadable files. These records can be made available in a variety of formats; contact the MBMG Mining Archives office for further information about accessing these records.
Mineral Museum Collection
The collection contains over 15,000 fine mineral specimens from throughout the world. Stored specimens are cataloged using the Hey system. Over 1,000 specimens are on display at the Mineral Museum on the campus of Montana Technological University in Butte, MT. The Museum is open to the public. More information is available at http://mbmg.mtech.edu/museum/museum.html.
Anaconda Research Laboratory Collection
The Anaconda Mining Company (ACM) compiled this collection of an estimated 80,000 specimens from 1940 through 1981. The collection includes polished study specimens and over 10,000 thin sections. Many of the rocks were collected in underground mine workings in Butte, Montana and are located on maps of the underground workings. Butte’s underground mines are now flooded, and the Anaconda Collection represents a unique set of samples from the region. Other specimens in the collection are from locations across the globe in which the ACM had commercial interests and/or evaluated for development. Samples were taken from various Montana mines. Contact the MBMG Mining Archives office for information about accessing this collection.

Abandoned and Inactive Mines Database
In the 1990s, MBMG staff conducted a comprehensive inventory of mine sites on or possibly affecting federal land under contract with the U.S. Forest Service and the U.S. Bureau of Land Management. Sites were initially identified using the U.S. Bureau of Mines Mineral Industry Location System (MILS) database. Sites were researched and either ‘screened out,’ because of low probability of impact to federal lands, or visited, described, and sampled if there was potential for environmental impact. Water sampling results from these visits are available through the MBMG Groundwater Information Center database http://mbmggwic.mtech.edu/. reports documenting visits and findings at each study area are available through the mbmg publications catalog by searching with the key words “abandoned mines” http://www.mbmg.mtech.edu/mbmgcat/catmain.asp
The Earthquake Studies Office (ESO) of the Montana Bureau of Mines and Geology opened in June 1980 to operate the Montana Regional Seismograph Network. The office collects and analyzes seismic data and reports earthquake information. The ESO also collects and stores seismograms recorded in Montana by other groups and agencies.
This collection of original paper seismograms includes those recorded on MBMG seismograph stations from 1980 through approximately 2010. Each box typically contains one month of seismograms. The collection also includes paper seismograms and microfilm records recorded at the University of Montana from 1972-1978; seismograms on photographic paper from the Bozeman (BOZ) World Wide Standardized Seismograph Station (WWSSN) from 1963-1968; the Missoula (MSO) WWSSN station from 1974-1985; and U.S. Army Corps of Engineers' Libby Dam network from 1970-1985. Contact Mike Stickney, Director, MBMG ESO for information about accessing these records, at (406) 496-4332 or firstname.lastname@example.org
Continuous digital data recorded since August 15, 2001, is archived at the IRIS Data Management Center. Recent seismogram images are available from the MBMG earthquakes website (http://mbmgearthworm.mtech.edu/webicorders/welcome.html).
The T.T. Baker collection consists of mining claim surveys completed by the T.T. Baker Company from 1870 through 1940. The collection includes survey maps, field survey books, and several books of original maps of eastern and southeastern extensions to the town of Butte, Montana. Contact the MBMG Mining Archives office for information about accessing these records.
Charles M. Hauptman
This collection contains information compiled by Charles M. Hauptman during his career as a geologist. It contains mining- and geology-related publications, correspondence, maps, sketches, and reports about various mining properties in eastern Montana. Contact the MBMG Mining Archives office for information about accessing these records.
Joseph T. Pardee’s interest in geology began in Philipsburg, MT and grew into a 32-year career with the U.S. Geological Survey. Documents in this collection (aerial photos, collection administrative documents, and maps) pertain to Pardee’s work, which ranged from glacial deposits to gold deposits, from mine sites to dam sites. Pardee’s career in the northwestern U.S. included an emphasis on the geology of Montana. Documents can be accessed through our archive search engine using the search term ‘Pardee’.
Personal papers (not geologically related) include mementos, photographs, diaries, newspaper clippings, and documents collected by Joseph T. Pardee and family, including Ruby S. Pardee (spouse), Mary Pardee Kelly (daughter), and Ralph R. Kelly (son-in-law). Contact the MBMG Mining Archives office for further information about accessing these records.
John W. Taber
The John W. Taber collection describes the Crystal Mountain Mine, in Ravalli County, which was one of only two fluorspar mines in Montana. Taber directed the mineral potential evaluation, development, production, and closure of the mine. The collection contains documents and maps related to mine geology, engineering, development, and production. Specimens include drill core samples, logs, and thin sections. Contact the MBMG Mining Archives office for information about accessing this collection.

MBMG Industrial Minerals and Sapphires Research Collection
During his 50 year career with the MBMG, Dr. Richard (Dick) Berg studied building stone, zeolites, barite, talc, bentonite, potash, vermiculite, and sapphires, in addition to geologic mapping. This research collection represents a diverse and unique primary source related to Montana’s industrial minerals.
The Industrial Minerals and Sapphires research collection includes approximately 40 boxes of specimens and thin sections, more than 100 field books, and a file of field maps. Materials relate to studies primarily about building stone, zeolites, barite, and talc conducted by Dick Berg from about 1966 through 2018. This collection supplements 94 MBMG publications and 46 external publications authored or co-authored by Dr. Berg. Digital copies of the field notebooks can be accessed through our archive search engine using the search word ‘Berg’. Contact the MBMG Mining Archives office for further information about accessing this collection.
New World Project
This collection contains information related to environmental assessment of the proposed New World Mine, adjacent to Yellowstone National Park in Park County, Montana. The proposed mine created substantial public concern and, in 1995, a public trust purchased the property and withdrew it from mining development. The collection contains over 53,000 pages of geologic, hydrogeologic, and geophysical data, and 1,217 related maps. These materials were amassed during mine development and environmental review processes; it represents the most comprehensive extant data set related to this world-class Eocene epithermal gold deposit.
Materials in the collection have been digitized and are available by contacting the MBMG Mining Archives office.
Further information is available through our MBMG Data Center . MBMG's databases are continually updated with new data from driller's logs, MBMG research projects, and research projects from other agencies.
