Silver Bow Mining has taken steps to advance its mining operations in Montana through leadership changes and infrastructure acquisition.

In late July 2026, the company appointed Doug Stiles as President to oversee the operational development of projects in the Butte Mining District. Stiles, a veteran of the Montana mining industry, was tasked with coordinating development for the company’s claims and surface rights around the Rainbow Block.

By late August 2026, the company expanded its capabilities by acquiring the Jefferson County Metallurgical Complex via insolvency proceedings. This acquisition includes a 1,000-ton-per-day flotation plant and tailings capacities, which the company intends to use as a processing hub for the Rainbow Block project. The deal involves an initial payment of approximately 28.6 million USD, with further payments linked to operational milestones. The facility also offers expansion potential for a 15,000 t/d mill.

In early September 2026, Silver Bow Mining reported its strongest drilling results to date at the Rainbow Block project. The company identified high-grade intercepts, including “1,586.1 g/t AgEq over 2.3 meters”. These results were located up to 125 meters outside existing resource boundaries, suggesting potential for resource expansion at the polymetallic site. With three drilling rigs currently operational, the company is working toward a major resource update scheduled for the first half of 2027.
