Aftermath Silver Begins Drilling at Berenguela Eastern Copper Target and Challacollo Silver Project in Chile Aftermath Silver Ltd. has commenced drilling at the eastern limits of the Berenguela mineral resource to investigate high grade copper intercepts from previous drill programs. Drilling has commenced on the eastern zone of Berenguela with 2 section lines planned 50 and 100m of the hole AFD139 which returned 69m @ 1.19% Cu + 78g/t Ag. Drilling on the eastern limits of the MRE also returned the longest copper intercept drilled to date at Berenguela in hole AFD100 which assayed 156m grading 1.12% Cu, 290 g/t Ag and 7.3% Mn beginning at surface. The initial program allows for up to 1,000m of core drilling but may be expanded depending on the results of the drilling. Aftermath Silver Ltd. has also started an initial 5-hole diamond core program of roughly 800m of diamond core drilling at the Challacollo project in Chile. Previous drilling concentrated on the principal vein (Lolón Vein) to a depth of about 200 m below surface. The oxidation level at Challacollo bottoms at approximately 200 m below surface. The down-dip extent of the mineralized structures remains unknown. Gold and base metal grades are generally observed to increase at depth. The main objective of the planned program is to investigate the potential to a) expand the existing resource at Challacollo by extending some of known veins down dip and along strike, b) initial drill testing of previously known but untested veins and suspected new veins on Aftermath's land package, and c) twin some previous RC holes to obtain supplementary geological and metallurgical information. Specifically: Lolón North: The northern sector of the Lolón vein is still unexplored and is partially covered by colluvial deposits. In the northern sector, which corresponds to the last vein outcrops, silver mineralization may continue to depth. Drilling is targeted to cut the main vein at a vertical depth of 60 meters; Lucy North: silver-bearing veins identified to the west of the main Lolón vein. Drilling will also target disseminated silver in the host rock. The structures have a similar orientation to the Lolón vein and are located north of the Lucy vein; Palermo North: a replacement breccia with galena and significant silver values located to the north of the Palermo North vein projection. Challacollo is located in Region I in Northern Chile, 130 km southeast of the major port city of Iquique and 50 km south of the town of Pica. The project is approximately 30 km east of the Pan American Highway, via Teck Resources’ Quebrada Blanca Copper Mine access road. The project is 139 km southeast of the major Pacific port city of Iquique. High voltage power transmission lines are located 15-30 km from the property, in part to service nearby mines of Collahuasi and Quebrada Blanca. The Project includes water rights. Table 1. Summary of the Mineral Resource Estimate for the Challacollo Silver-Gold Project: Classification Material Type Tonnes (Kt) Silver (g/t) Gold (g/t) Silver (Koz) Gold (Koz) Indicated Open Pit 5,597 170 0.27 30,639 49 Underground 1,043 134 0.29 4,510 10 TOTAL 6,640 165 0.27 35,150 58 Inferred Open Pit 2,360 117 0.15 8,912 11 Underground 443 157 0.26 2,232 4 TOTAL 2,803 124 0.17 11,144 15. Mineral Resources are constrained by an optimized pit shell at a long-term metal price of USD 20/oz Ag with recovery of 92% Ag and metal price of USD 1,400/oz Au with recovery of 75%. Silver equivalency formula is AgEq (g/t) = Ag (g/t) + 57.065 *Au (g/t). The open pit mineral resources are based on a pit optimization using the following assumptions: Plant feed mining costs of USD 3.5/t and waste mining cost of USD 2.5/t. Processing costs of USD 17/t and General and Administration costs of USD 2.5/t. Edge dilution of 7.5% and 100% mining recovery. 45-degree slope angles. Cut-off grade is 35 g/t AgEq g/t. The underground mineral resources are reported within Datamine MSO stopes based on the following assumptions: Mining costs of USD 35/t. Processing costs of USD 17/t and General and Administration costs of USD 2.5/t. Minimum width of 2.5 m. No dilution or mining recovery. Cut-off grade is 93 AgEq g/t. Bulk density used was 2.47 t/m3. Drilling results up to 31 December 2016. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The numbers may not compute exactly due to rounding. Mineral Resources are depleted for historic mined out material. Announcement • Jun 17

("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"). Announcement • Feb 13
Aftermath Silver Ltd. Launches Berenguela Pre-Feasibility Study Aftermath Silver Ltd. announced the commencement of a Pre-Feasibility Study for its Berenguela silver- copper-manganese project in southern Peru, 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 CAD 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 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.
