(CSE: SLV,OTC:SLVDF) (OTCQX: SLVDF) (FSE: 4YW) is pleased to announce it has signed an asset purchase agreement (the ‘Agreement’) with Bunker Hill Mining Corp., whereby Bunker Hill Mining Corp. and its subsidiary (together, ‘Bunker Hill’) will acquire from Silver Dollar Resources Inc. and its subsidiary (together, ‘Silver Dollar’ or the ‘Company’), the right, title and interest in the assets related to the Ranger-Page Project located in Shoshone County, Idaho, USA (the ‘Target Assets’), which includes Silver Dollar’s 75% interest in the Government Gulch property and its related option rights under the Government Gulch Option and Joint Venture Agreement (the ‘Government Gulch Agreement’) and the Page Mine Mineral Rights Lease and Option Agreement (the ‘Page Mine Agreement’).

Sam Ash, President and CEO of Bunker Hill Mining, stated: ‘The addition of the Ranger-Page Mines represents another step in our vision to re-establish Bunker Hill as a leading producer in the Silver Valley. The Ranger-Page workings and mineralized zones are geologically continuous with the Bunker Hill system, offering immediate synergies for exploration, development, and potential future production.’

‘Amalgamating the Ranger-Page Project with Bunker Hill Mining is a strategic and logical transaction that aligns perfectly with the plan we contemplated when we acquired the Project last year,’ said Greg Lytle, President and CEO of Silver Dollar. ‘While the transaction has happened faster than expected, we are confident the timing is optimal for both companies. Ranger-Page enhances Bunker Hill’s exploration prospects and provides Silver Dollar with a strong equity position in a near-term producer, benefiting from the upside of the combined assets.’

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 ongoing restart of operations at the Bunker Hill Mine, targeted for H1 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 (IP) surveys have identified anomalies, and where surface trenching 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.
