Aftermath Silver intercepts 77 g/t Ag + 2.93% Cu over 30.0 m at Berenguela

Vancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (the "Company" or "Aftermath Silver") is pleased to provide additional assay results from its Phase 3 diamond drill program at the Berenguela silver-copper-manganese deposit located in the Department of Puno in southern Peru. Results are reported for the last 15 holes from the 90-hole program of diamond core drilling. These holes are infill drilling along a 100m strike length within the limits of the existing resource.

They are aimed at delineating high-grade mineralization suitable for mining as a starter pit in the planned future mining operations and at defining the extent of mineral occurrences for planning purposes. In total, Aftermath has completed 15,540m of core drilling in 3 phases of diamond drilling. Drill plans, sections and summary drill logs are available on Aftermath's website: https://aftermathsilver.com/projects/berenguela/plans-and-sections/ .

Highlights of the current drilling include: AFD184 returned 62.3m @ 81 g/t Ag + 1.99% Cu + 19.2% Mn from 5.6m downhole;        Including 30.0m @ 77 g/t Ag + 2.93% Cu + 21.0% Mn from 26.2m downhole AFD190 returned 24.5m @ 293 g/t Ag + 0.81% Cu + 14.3% Mn from 26.3m downhole;        Including 4.95m @ 882 g/t Ag + 0.21% Cu + 17.4% Mn from 50.3m downhole AFD187 returned 42.2m @ 99 g/t Ag + 1.61% Cu + 18.1% Mn from 2.40m downhole;        Including 14.0m @ 89 g/t Ag + 2.91% Cu + 16.2% Mn from 30.50m downhole Ralph Rushton, President and CEO, commented "The infill drilling around the potential starter pits is now complete and the results will underpin the metallurgical testwork and mine scheduling for the ongoing pre-feasibility study. Drilling in the area known as Domain 2, around the small historic open pit, has delivered excellent copper
