Vancouver, June 16, 2026 - Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (the "Company" or "Aftermath Silver") has signed a strategic advisory engagement with Global Frontier Advisors L.P. ("GFA"), a Washington, D.C.-based firm whose partners include former senior U.S. military officers, diplomats, and international business executives.

In connection with the engagement, Aftermath has formed an Advisory Board and named three GFA founding partners as inaugural members: Lieutenant General David Bellon (USMC, Ret.), Lieutenant General Michael S. Groen (USMC, Ret.), and Ambassador James "Jimmy" Story (Ret.). A formal Advisory Services Agreement took effect March 27, 2026, with the Company's newly formed U.S. subsidiary, U.S. Critical Minerals Corp. ("USCMC").

The Advisory Board has been established to support the strategic positioning of Aftermath's 100%-owned Berenguela silver-copper-manganese project in Peru and the downstream development work being undertaken through USCMC. Berenguela is a potential future source of silver, copper and manganese for U.S.-aligned supply chains. The Company is exploring partnerships, offtake arrangements and funding structures to advance Berenguela in line with the U.S. administration's objectives of securing Western Hemisphere critical metals feedstock for U.S.-based refining capacity. The Company believes this positions Aftermath Silver as a strategically significant solution for the U.S. battery and defense materials' supply chains.

Michael Williams, Executive Chairman of Aftermath commented "At Berenguela, Aftermath is developing a potentially large Western Hemisphere silver-copper-manganese feedstock source and has assembled the right people with the right technical capabilities to execute development of the project. Working with GFA, we are confident that the Berenguela story will continue to reach the right decision-makers in Washington and that the project is recognized as a crucial strategic international asset."

Commenting on behalf of GFA, Lt. General David Bellon, USMC (Ret.), a member of the new Advisory Board said: "The strategic case for this project is clear, but the economic one is equally compelling. A U.S. domiciled critical metals facility means skilled American jobs and a domestic processing anchor for industries that today must import much of the critical minerals they need. Its impact runs well beyond the plant gate, strengthening the entire value chain that depends on this material - from battery and cathode manufacturing to grid-scale storage. This opportunity is a great example of how durable, allied supply chains can drive economic resilience in America."

His colleague and fellow advisory board member Ambassador James "Jimmy" Story (Ret.) added "Today marks a significant step forward for Aftermath Silver. The GFA Advisory Board connects Aftermath's technical and commercial work on Berenguela to the U.S. government and provides the engagement that a project of this strategic importance requires. It connects senior GFA advisors who have deep national security and critical-minerals expertise with the Aftermath team, and positions Aftermath to advance Berenguela, helping to establish a domestic, allied supply chain for a critical battery and defense materials, and building long-term value for Aftermath's shareholders."

With these advisors joining its Advisory Board, USCMC gains senior-level access and credibility across the U.S. national security, defense, energy, and development-finance communities. Their collective standing is intended to strengthen the Company's ability to engage the relevant departments and agencies and to identify and pursue federal and state funding and procurement pathways for which the project may be eligible, potentially including programs under the Defense Production Act and those administered by the U.S. Department of Energy, the Export-Import Bank of the United States, and the U.S. International Development Finance Corporation, among others.
