Vancouver, British Columbia--(Newsfile Corp. - November 24, 2025) - Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (FSE: FLM1) (the "Company" or "Aftermath Silver") is pleased to announce that it has completed the final payment to complete the acquisition of the Berenguela silver-copper-manganese project ("Berengula") ahead of the November 2026 due date.

In return for early payment, EMX Royalty Corporation ("EMX") agreed to reduce the final payment by US$100,000 to US$1.55-million, and SSR Mining Inc. ("SSR") concurrently agreed to waive Aftermath's obligation to complete and file a Pre-Feasibility Study by November 23, 2025 as would have been required by the amended Berenguela Acquisition Agreement.

Aftermath has now fulfilled all payment obligations under the Acquisition Agreement and looks forward to working with SSR to complete the transfer of ownership of Berengeula.

Ralph Rushton, President and CEO of Aftermath, commented: "I would like to thank David Cole and the team at EMX for working with us throughout the agreement, and SSR for its cooperation as we conclude the acquisition of Berengula. Making this final payment allows us to secure 100% ownership of the Berenguela silver-copper-manganese project for Aftermath but more importantly puts us in the driver seat of a what has become a very important critical metals project. We are initiating a comprehensive pre-feasibility study for Berenguela contemplating production of silver, copper and manganese."

Deal Terms

EMX's interest in Berenguela resulted from EMX's acquisition of a portfolio of royalty interests and payments from SSR and certain of its subsidiaries (see EMX news releases dated July 29 and October 21, 2021). Aftermath has completed its payment obligations, which arise pursuant to a definitive acquisition agreement, originally executed with SSR totalling US$13-million and other consideration to acquire a 100% interest in the Project.

Current Berenguela Mineral Resource Estimate

Table 1. Berenguela Ag-Cu-Mn deposit Mineral Resource as of 31 January 2023

Notes:

• CIM Definition Standards (2014) were used for reporting the Mineral Resources.
• The effective date of the estimate is 31 January 2023.
• The Qualified Person is Dinara Nussipakynova, P.Geo., of AMC Mining Consultants (Canada) Ltd.
• Mineral Resources are constrained by an optimized pit shell using the assumptions in Table 2.
• No dilution or mining recovery applied.
• Silver equivalency (AgEq) formula is AgEq = Ag+ Cu%*121.905+Mn%*22.809+Zn%*41.463 based on the parameters in Table 2.
• Cut-off grade is 80g/t AgEq.
• Bulk density used was estimated and variable. but averaged 2.30 tonnes/m³ for mineralized material and 2.25 tonnes/m³ for waste.
• Drilling results up to 13 October 2022.
• 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.
• The relative value in the Mineral Resource by metal is as follows, Ag=26% Cu=26%, Mn=44%, Zn=4%.

The Mineral Resource estimate used conceptual open pit mining constraints for reporting purposes and is presented in Table 1. Mineral Resources are stated at a cut‐off grade of 80 g/t silver equivalent (AgEq) which equates to a 3.55% manganese equivalent cut-off grade. The relative value in the Mineral Resource by metal is as follows, Ag=26%, Mn=44%, Cu=26%, Zn=4% using metal prices for Agri-MnSO4 which generally trades at a considerable discount to battery grade manganese sulphate. 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.
