Mining Companies Incorporated In Utah
This list is not comprehensive in any way, and is not meant to be. It is a partial listing only, many companies organized and incorporated after 1925. From the mid-1920s onward, few small mining companies used railroads to move their ore, especially in single-car shipments. Instead these small mining companies preferred to ship their ore by truck, over the publically-funded roads and highways. The informal term 'truck mine' soon became the way to describe these small mining companies.
In almost every case, because these mines were all small operations, if a railroad was involved the ore would have been loaded at a trackside dump, loading a single rail car parked for the purpose. In most cases, it would take a week or more to fill one rail car.
The source of this list was a handwritten list maintained while doing other research in the 1979-1983 time period.
The compilation of this list was completed as a listing of mining and associated companies that might have been served by a railroad. Corporations with a Utah index number higher than 16800 were not noted due to their being incorporated after about 1925, except those companies whose names were recognizable. Subsequent interest in Utah historical subjects has made this listing very useful.

The files for these companies were examined at Utah Secretary of State's office starting in October 1979, during a daily one-hour lunch period. The work took place inside the large, original walk-in vault in that office in the state capitol building. Within a few years, all files and storage boxes were moved to the archives' new facility west of Redwood Road, in West Valley City. The archives are now located adjacent to the former Rio Grande depot, closer to downtown Salt Lake City.
