Nevada Bureau of Mines and Geology (NBMG) Open-File Report 10-8
NBMG Mining District File Collection
with Index, Search Engine, and Other Nevada Mineral Related Files
(2nd edition, 2010)
(Additional revisions and edits made in 2014 by Ron Hess)
Compiled by Ronald H. Hess, Martha Henson, David A. Davis, Richard O. Meeuwig, Kristen A. Scott, and Karen Boldi.
The Mining District Files consist largely of historical and current
maps, reports, articles, photographs, correspondence, assays, production
reports, and reserve information on all aspects of mining in Nevada.
These have largely been donated to the NBMG over the years from
individuals, companies, and other government agencies. The files were
originally created, named, and numbered using NBMG Map 37, Metal Mining Districts of Nevada
(Schilling, 1976), as an index. In this system, the files are divided
alphabetically by county and then alphabetically by district name within
each county. Each district has a file, and each county has a general
file for things that cannot easily be included in a district file. Map
37 has been superseded by NBMG Report 47, Mining Districts of Nevada,
(Tingley, 1998), which is much more complete than Map 37 and is very
useful in conjunction with this database. The current mining district
naming convention used in this index is based on Report 47. See Map of Mining Districts in Nevada, dated 1946, for a more historical reference on Nevada mining district locations.
Over the last several years NBMG has undertaken the digital conversion
of these paper documents into scanned images. The files contained here
are in Arcobat PDF file format. To view the scanned images you must have
a file viewer such as Acrobat reader or other software that will open
and view a PDF file. Some of these files are large (up to 500 megabytes)
so you should have a high speed connection if you wish to view the
scanned version of the documents
SOME OF THE DOCUMENTS, MAPS, AND WELL LOGS CONTAINED IN THIS PROJECT ARE VERY LARGE AND MAY TAKE A WHILE TO DOWNLOAD AND VIEW.
The digital file conversion project at NBMG is ongoing. If you have
questions about the files contained in this project contact Ron Hess at
Click here to search the index for district, county, title, author, date, PMC, and/or commodity. Make
the search script. This is a large script and my take a few moments to
load. You can search all fields (including notes) simultaneously by
entering a search string in the "All Fields" box. The scanned PDF file
is linked to the identification number in the first column of the search
results table, and can be viewed in Adobe Reader by clicking this
A list of the scanned Mining District Files, in html format, is available by clicking here.
No: Unique number that identifies each item in the collection. Items
that have been scanned and converted to Acrobat PDF file format are
live linked to this field.
District: Name of the mining district. Many districts have more
than one name. These other names are cross referenced in NBMG Report 47.
Documents that describe areas outside of an established mining district
are assigned as county general files. County general files are
identified by having the county name followed by the word “general.”
County: The present name of the county the mining district is in.
Some districts span more than one county and are usually included in
the county containing the bulk of the district. Also, in old items, some
counties did not yet exist. Examples include Clark County, which was
split from Lincoln County in 1908, Mineral County, which was split from
Esmeralda County in 1911, and Pershing County, which was split from
Humboldt County in 1919. Also, some counties have changed names.
Examples include Roop County, which became part of Washoe County in
1883, and Ormsby County, which was consolidated with and renamed Carson
City in 1969.
Title: Title of the document or map. Many items do not have a formal title, and an informal title was created.
Author: Author(s) name or it may list the name of the agency that
prepared the report or map if the authorship was not apparent on the
document. If the author and the publishing agency are not known, then
the field contains "unknown" or is left blank.
Date: Date the document or map was published. If the date is not known, then the field contains "unknown" or is left blank.
PMC: Includes property, mine, claim, and company names when identified.
Commodity: This field lists commodities and/or minerals that were identified in the document.
Notes: This field includes miscellaneous information not given in
other fields and additional information that may not have fit in to
other fields because of field length limitations.
