Mining Companies Incorporated In Utah

(Return to Mining Index page)

Examined at Utah Secretary of State's office during October 1979. The work took place inside the large, original walk-in vault in that office. 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.

This is a partial listing only, many companies organized and incorporated after 1925 were not noted. 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.

(Index numbers shown in parentheses are those of predecessor companies.)

(Dates shown in parentheses are the dates of disposition from predecessor companies.)
