SILVER DOLLAR COMPLETES SALE OF RANGER-PAGE SILVER-ZINC-LEAD PROJECT TO BUNKER HILL MINING

Further to the news release of Oct. 27, 2025, Silver Dollar Resources Inc. has completed the sale of the Ranger-Page project, whereby Bunker Hill Mining Corp. and its subsidiary have acquired from Silver Dollar and its subsidiary the right, title and interest in the assets related to the Ranger-Page project located in Shoshone county, Idaho, United States, which includes Silver Dollar's 75-per-cent interest in the Government Gulch property, its related option rights under the Government Gulch option and joint venture agreement, and the Page Mine mineral rights lease and option agreement.

"Finalizing this transaction represents the successful execution of our strategic vision for Ranger-Page. The closing immediately establishes Silver Dollar as a significant and supportive shareholder in a near-term producer, providing our investors with direct, leveraged exposure to the restart of the Bunker Hill mine that is on track for first production in H1 2026," said Greg Lytle, president and chief executive officer of Silver Dollar. "We believe this transaction delivers an accelerated path to value creation for our shareholders compared to the independent development of Ranger-Page, and we look forward to the growth of Bunker Hill in the years ahead through production and exploration."

Strategic highlights:

• Consolidated land position: The acquisition unites the Ranger-Page and Bunker Hill properties into a contiguous land package, creating one of the largest and most prospective holdings by any single company in the Silver Valley.
• Exploration upside: Historical drilling and production data from the Ranger-Page indicate high-grade silver-lead-zinc mineralization along the Page vein system, which remains open at depth and along strike.
• Infrastructure synergies: The Ranger-Page mines' existing underground workings and surface access points could provide additional flexibility for future mine planning, ventilation and exploration access to deeper levels of the Bunker Hill system.
• Complementary to restart plan: The acquisition is aligned with Bunker Hill's continuing restart of operations at the Bunker Hill mine, targeted for first half 2026, and enhances the company's upside optionality for future resource expansion and mill feed sources.
• Community benefits: This has the potential to create more local employment opportunities within the Silver Valley and stimulate procurement from regional suppliers in ways that benefit the local communities.

About the Ranger-Page project

Located in a world-class silver district, the Ranger-Page land package covers six historic mines and adjoins the Bunker Hill mining property. The primary target areas are up and down plunge from historic underground mining, along strike where ground induced polarization surveys have identified anomalies and where surface trenching has identified near-surface mineralization. Additional exploration targets have also been identified away from historic mine infrastructure, using soil geochemical data, mapping and ground IP survey data.
