Aftermath Silver Launches Berenguela Pre-Feasibility Study

Vancouver, February 12, 2026 - Aftermath Silver Ltd. (TSXV: AAG) (OTCQB: AAGFF) is pleased to announce the commencement of a Pre-Feasibility Study ("PFS") for its Berenguela silver-copper-manganese project in southern Peru ("Berenguela" or the "Project"), marking a key milestone in the Company's strategy to advance the Project toward a production decision.

The decision to advance Berenguela to a PFS follows the completion of a C$20 million equity financing and an 82-hole infill drilling program completed in 2025 that intercepted mineralization in 95% of the holes. The updated Mineral Resource Estimate (See Aftermath news release dated December 4, 2025) materially improved confidence in the geological model and confirmed robust silver and copper mineralization across key zones, underpinning the Project's progression to the next stage of development. The PFS will build on the improved geological confidence delivered by the infill drilling program and represents the next major milestone on the Company's development pathway.

Ralph Rushton, President and CEO of Aftermath Silver, commented: "Aftermath is entering a transformational phase, supported by a strong balance sheet and a high-confidence resource base. The results of our infill drilling and updated resource have provided the technical foundation to advance Berenguela to a Pre-Feasibility Study, an important milestone for the Company. After a detailed review process carried out by our engineering team, we will be announcing the formal appointment of the successful engineering consultancies in the coming week. At the same time, we will be drilling key exploration targets at Berenguela and at our Challacollo silver project in Chile, to maintain strong exploration momentum across the portfolio."
