Aftermath Silver outlines drill plan for Challacollo

Executive Summary

• Aftermath Silver announced a planned 7‑ to 10‑hole diamond core drilling program (up to 2,000 m) at the Challacollo Ag‑Au project in northern Chile for Q4 2025.
• The program aims to extend known veins down‑dip, test previously identified but untested veins, and obtain additional geological and metallurgical data.
• Execution of the drill campaign will provide material needed to expand the existing silver resource at Challacollo.

Key Details

• Program Scope: 7–10 diamond core holes, up to 2,000 metres total drilling in Q4 2025.
• Target Zones:
• Lolon North – cut main vein at ~60 m vertical depth to assess continuation below colluvial cover.
• Lucy North – test silver‑bearing veins west of the main Lolon vein and disseminated host‑rock mineralization.
• Palermo North – evaluate a replacement breccia with galena and notable silver values north of the Palermo vein projection.
• Millsite Vein – investigate a structurally downthrown vein offset east of Lolon, anticipated below 250 m depth.
• Objectives:
  1. Expand existing resource by extending known veins down‑dip and along strike.
  2. Conduct initial drill testing of previously identified but untested veins and potential new structures within the land package.
  3. Twin selected reverse‑circulation (RC) holes to acquire supplementary geological and metallurgical information.
• Geological Context: Challacollo is a low‑sulphidation epithermal Ag‑Au vein system with a substantial silver resource; gold and base‑metal grades are observed to increase with depth.
• Location Details: Project situated in Region I, northern Chile, ~130 km SE of Iquique, 50 km south of Pica, near major transport infrastructure and power lines.
• Qualified Person: Michael Parker (F.AusIMM), non‑independent director, reviewed and approved the technical content per NI 43‑101.
