Welcome to the Gold Bar Museum
It took many participants to make this true story happen. This included miners, assay personnel, investors, banks, newspapers, railroads, engravers, and artists. The whole story was the "brain child" and funded by Colonel Charles A. Broadwater. In September 1889 eight days before the gold bar was poured, Colonel Broadwater had just opened the Broadwater Hotel and Natatorium. He was also the President of the Montana National Bank and the President of the Montana Central Railway. The railway was a spur line of the Great Northern railroad running between Butte, Great Falls, and Helena including Rimini and Marysville gold camps. The Colonel and the Montana National Bank collected the gold that was used in the making of this large historical bar over a six year period. Although, most of the bullion was from the three mines; the Spotted Horse, Drum Lummon, and Jay Gould mines. One of Colonel Broadwater’s largest bars in his collection was 290 pounds. That bar was then melted as part of the making of this famous Gold Bar.
Tuesday, Sept. 3rd 1889 the largest gold bar in the world was poured at The U.S. Assay Office Helena located at
206 Broadway.
A pour this large was not common. The pour took 6- men 8- hours to complete using custom built molds and the largest crucible.
