Silver Bow Mining, an exploration-stage mining company with projects in Montana, filed on Friday with the SEC to raise up to $40 million in an initial public offering.
The company owns approximately 3,347 acres in patented mineral claims in Silver Bow County, Montana, and is focused on silver, zinc, gold, lead, and copper. Silver Bow Mining's primary mineral claim property is called the Rainbow Block, which is composed of approximately 878 acres of mineral rights, and is its only material property under active exploration and development. In addition to Rainbow Block, the company has approximately 2,469 acres of mineral rights in Silver Bow County, represented by the Marget Ann Block, the Goldsmith Block, the Travona Block and the Emma Block. Silver Bow Mining has yet to generate revenue.
The Butte, MT-based company was founded in 2020 and plans to list on the NYSE American, although it has not yet selected a symbol (RC ticker: SBOW.RC). Silver Bow Mining filed confidentially on October 2, 2025. Cantor Fitzgerald and Mackie Research Capital are the joint bookrunners on the deal. No pricing terms were disclosed.
