The Goldfield Consolidated Mines Company Records (1904-1930) consist of correspondence, invoices, receipts with voucher checks, mining leases, insurance policies, payroll accounts, published notices and articles. Also included is a monthly Goldfield Consolidated Mines reports ledger from February 1914 to October 1916 for mines located in the south central Nevada area. The collection primarily dates from 1904, before the consolidation when the boom in Goldfield was beginning in earnest, until 1919, when the company ceased its operations in Goldfield, although there are a few records post-1919 as the company continued to exist after the mines and mill closed down.
