The records of the Aurum Mining Company span the years 1916 to 1953, with the bulk of the material covering the years 1927 to 1947. Included are minutes of meetings, annual financial reports, correspondence, legal documents, capital stock records, financial ledgers and journals, ore settlement records, and payroll records.

Of particular note in these records is the relative absence of stock and personnel records and, in contrast, the great amount of correspondence and related records. This latter, for reasons not easily apparent was divided into three separate alphabetical files, all from the same office but overlapping somewhat in time and much in subject matter.
