The companies that comprised the Big Five changed frequently. Company secretary Nathan C. Merrill's corporate history begins with the Orphan Boy Extension Mining and Milling Company, which was organized in August, 1892 near Copper Rock in Boulder County, Colorado. In 1894, the company purchased the Dew Drop Mine from John T. Duncan. Expansion continued in June 1895, when the company added the Adit Mining Company. In June 1897, the Adit Tunnel Company was organized. The Ni Wot Mining Company, located in Clear Creek County, Colorado, was organized in January, 1898.
In 1900, the Big Five began to consolidate its constituent companies. The Adit Tunnel Company sold its assets to the Big Five in August or September of that year, as did the Dew Drop. The Ni Wot followed in 1903.
The Big Five organized several subsidiary companies in September 1900, including the Big Five Tunnel, Ore Reduction and Transportation Company. This was followed by the Big Five Trust, the Big Five Expenses and the Big Five of Arizona. Each company kept separate books, however, dates of incorporation are not available.
Most of the affiliated companies appear to have merged into the Big Five Tunnel, Ore Reduction and Transportation Company by August of 1906.
