All mining claims are recorded with the County Recorder. Taxes are assessed by the County Assessor and paid to the County Treasurer. All disputes over mining claims were decided in District Courts, whose records are filed with the County Clerk. The claim may also be described in the tax assessment records, filed with the County Assessor.
The State did not keep any records of individual mining claims except where the matter of location or claim was appealed to the Supreme Court.
Incorporated Mining Companies
Mining Companies incorporated in the State filed their articles of incorporation with the Secretary of the Territory from 1861 to 1864 and with the Secretary of State beginning in 1865. The State Archives has some of these incorporation records from 1861 to 1926. Mining companies that incorporated in another state were not required to file papers with the state until 1891. They did have to file information with the County Clerk in the County in which the corporation did business. The Secretary of state maintains a record of all active corporations or those that disincorporated after 1926.
A compilation of all domestic and foreign corporations, 1865-1912, can be found in the Biennial Report of the Secretary of State for the years 1911-1912, published in the Appendix to the Journals of the Senate and Assembly, in 1913.
State Mine Inspector
The State Mine Inspector kept card files showing mines in operation from 1909 to 1974. They are filed by company name by year. The records for the years 1909-1974 are in the State Archives with an alphabetical file of all company names for all years. This record series also includes some description of the mine's operation, addresses of managers, licenses of hoist operators (1922-1971) and mining accidents (1909-1971), both fatal and non fatal. These accident reports are now maintained by the Nevada State Industrial Insurance System.
