Aftermath Silver Begins Drilling at Berenguela Eastern Copper Target and Challacollo Silver Project in Chile

Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (the "Company" or "Aftermath Silver") is pleased to announce that drilling has commenced at the eastern limits of the Berenguela mineral resource to investigate high grade copper intercepts from Aftermath's previous drill programs. A limited drill program is also underway at the Challacollo Ag-Au project in Region 1 of northern Chile. Challacollo is a highly prospective low-sulphidation epithermal Ag-Au vein deposit containing a substantial silver resource (see Table 1 below). Ralph Rushton, President and CEO of Aftermath, said: " We have started drilling the eastern copper target at Berenguela to investigate the potential for high grade copper mineralization beyond the limits of the existing MRE. Our previous drilling in 2024/2025 on the eastern margins of the MRE was extremely positive and with the copper spot price close to its all-time high I look forward to reporting on the results of the drilling later this year. Our team has also begun drilling at the Challacollo silver-gold project, which gives Aftermath further silver exposure in addition to our flagship Berenguela Project in Peru. Our objective at Challacollo is to expand and increase the mineral resource and this is the first step toward that goal." Berenguela Eastern Copper Target 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 (see news release dated June 9, 2025). Drilling on the eastern limits of the MRE also returned the longest copper intercept drilled to date at Berenuela in hole AFD100 which assayed 156m grading 1.12% Cu, 290 g/t Ag and 7.3% Mn beginning at surface (see Aftermath's News release dated February 27, 2025.) The initial program allows for up to 1,000m of core drilling but may be expanded depending on the results of the drilling. Challacollo Silver-Gold Project Aftermath 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; About Challacollo 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 transmis...
