Aftermath Silver Files Technical Report

Vancouver, January 16, 2026 - Aftermath Silver Ltd. (TSXV: AAG) (OTCQB: AAGFF) (the "Company" or "Aftermath Silver") has filed a technical report (the "Berenguela Technical Report") on the Berenguela silver-copper-manganese deposit located in the Department of Puno in southern Peru ("Berenguela" or the "Project").

The Report presents a new Mineral Resource Estimate for the Berenguela Silver-Copper- Manganese Project together with recommendations for further metallurgical and engineering work with the objective of completing a preliminary feasibility study during 2026. The company is now proceeding to initiate advanced engineering work on the project focused on commercializing the flowsheets for silver, copper and zinc recovery and the potential manganese products, which include battery grade manganese sulphate (MnSO4).

The Berenguela Technical Report, titled "NI 43-101 Technical Report, Mineral Resource Estimate for the Berenguela Project Province of Lampa, Department of Puno, Peru", is filed in accordance with National Instrument 43‐101 ("NI 43‐101") and was completed by BBA International (Canada) Inc. ("BBA"), with an effective date of November 30, 2025. The Qualified Persons for the Berenguela Technical Report are D. Nussipakynova, P. Geo. (BC & ON), D. Evangelista, P.Eng. (BC), and B. Arthur, PE (SME-Registered Member).

Mineral Resource Estimate

Table 1. Berenguela Ag-Cu-Mn deposit Mineral Resource at 137.40 USD NSR as of November 30 2025

Notes:

• CIM Definition Standards (2014) were used for reporting the Mineral Resources.
• The effective date of the estimate is November 30, 2025.
• The Qualified Person is Dinara Nussipakynova, P.Geo., of BBA International Inc.
• Mineral Resources are constrained by an optimized pit shell using the assumptions in Table 2.
• No dilution or mining recovery applied.
• The NSR cut-off value of USD137.40 is based on the following:
  • Long-term metal prices for Ag $29.73/Oz, for HPMSM $2592/t, for Cu $4.34/Lb, Zn $1.21/Lb
  • Metallurgical recoveries are 94% for Ag, 85% for Mn, 90% for Cu, and 85% for Zn
  • Payability for Ag is 99.8%, for Mn 100%, for Cu 96.75%, for Zn 85%
• Bulk density used was estimated and variable. but averaged 2.30 tonnes/m³ for mineralized material and 2.14 tonnes/m³ for waste.
• Drilling results up to 28 February 2025.
• 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 historically mined out material.
• The relative value in the Mineral Resource by metal is approximately as follows: Ag -13 % Cu -11 %, Mn-75 %, Zn-1 %.

The Mineral Resource estimate used conceptual open-pit mining constraints and is presented in Table 1. Mineral Resources are stated at a cut‐off grade of $137.40 NSR, determined based on economic assumptions provided below. The approximate relative value in the Mineral Resource by metal is as follows: Ag - 13%, Mn - 75%, Cu - 11%, Zn - 2%. The primary economic driver of the project is the high-purity manganese sulphate monohydrate (HPMSM) content. The model is depleted for historical mining activities. The assumptions for the open pit optimization exercise to constrain the Mineral Resource and confirm reasonable prospects for eventual economic extraction are shown in Table 2.
