Metalsource Mining Announces Management Transition as Silver Hill Exploration Advances

Dale Moore continues to guide drilling operations as Tom Kleeberg transitions to a consulting role.

Metalsource Mining Inc. (CSE: MSM) (OTCQB: MSMMF) (FSE: E9Z) ("Metalsource" or the "Company") announces a management transition that maintains continuity across its technical and operational teams as exploration activities advance at the Silver Hill Project in North Carolina.

As part of a previously planned management transition, Tom Kleeberg has resigned as Chief Operating Officer, effective November 10, 2026, and will continue supporting Metalsource as an independent consultant. Metalsource thanks Mr. Kleeberg for his contributions over the past year and looks forward to his continued involvement in property relations, infrastructure coordination and site-related matters.

Project Geologist Dale Moore, who has been instrumental in guiding the Company's drilling program, will continue to direct and coordinate exploration activities alongside Metalsource's technical and field teams. With two drill rigs operating and larger stepouts targeting extensions beyond the historic mine workings, the Company remains focused on investigating the broader scale of the Silver Hill polymetallic system.

Joe Cullen, Chief Executive Officer of MetalSource Mining, commented:

"Tom has made a meaningful contribution during an important period in Silver Hill's evolution, and we sincerely appreciate his leadership and commitment. We're pleased he'll remain involved, allowing us to continue benefiting from his extensive regional knowledge and relationships with local landowners.

"Dale Moore has been instrumental in guiding our drilling program and advancing our geological understanding of Silver Hill. With Dale and our technical team driving exploration, we remain laser-focused on aggressive expansion drilling and larger stepouts as we investigate what we believe could be a substantially larger polymetallic system. We have built a strong foundation, and our priority is to build on that momentum."

Tom Kleeberg commented:

"It has truly been a privilege serving as Chief Operating Officer of Metalsource over the past year as the Silver Hill Project has advanced from the initial validation of historical work into a systematic exploration program incorporating core drilling, geophysics, geochemistry, and 3-D modeling. This coordinated effort, led by a highly qualified team of technical and field experts, continues to advance our understanding of the Project's expanding polymetallic system. As I transition from my executive role, I look forward to maintaining my long-standing relationships with Silver Hill land owners, and continuing to support the project through property relations, infrastructure coordination, and environmental and site related matters. I am proud of the progress made by the Metalsource team and remain optimistic about the future of the Silver Hill."

Mr. Kleeberg will continue working with the Company as an independent contractor, providing support for property owner relations, land-related activities, logistics, site infrastructure, security and environmental matters.
