Vancouver, British Columbia--(Newsfile Corp. - May 22, 2024) - Aftermath Silver Ltd. (TSXV: AAG) (OTCQB: AAGFF) (the "Company" or "Aftermath Silver") is pleased to announce that its wholly owned Peruvian subsidiary, Aftermath Silver Peru S.A.C, has obtained drilling approval via the amendment of its Semi-Detailed Environmental Impact Assessment (MEIAsd), for the further development of the Berenguela Project in Puno, Peru. This amendment was granted on 29^th April 2024 by a Directorial Resolution of the Mining Environmental Authority of the Peruvian Ministry of Energy and Mines (Resolucion Directoral No. 0120-2024-MINEM/DGAAM de 29 de abril de 2024) and grants a 30-month period for drilling activities from the date that the company informs the General Mining Authority of the Peruvian Ministry of Energy and Mines of the commencement of works.

The MEIAsd includes 140 drillpads consisting of 115 drillpads for diamond drilling (up to 329 holes), and 25 drillpads for reverse circulation drilling (up to 75 holes). Access agreements with surface rights holders are in place and the drilling program can be initiated.

Ralph Rushton, CEO and Director commented, "We are very pleased to have received the approval for additional exploration and development drill programs at Berenguela and thank the Peruvian authorities for their support in approving our planned activities. We believe this approval allows us to execute infill and engineering drilling through the Preliminary Economic Assessment and Pre-feasibility phases of the project. Our technical team is currently designing a program to confirm and explore for high-grade mineralization on the margins of the known mineralization, and to complete other engineering drilling required to support our ongoing studies."

Berenguela Project: Background

• The Company has an option to acquire a 100% interest in Berenguela through a binding agreement with SSR Mining.
• Berenguela hosts a potentially open-pittable silver-copper-manganese resource close to Santa Lucia in Puno province, southern Peru.
• Silver, copper and manganese have crucial industrial applications in the clean energy and battery spaces. Copper and manganese have been designated critical metals by the US government and the European Union.
• The project is less than 6km from road, rail and power lines and 4 hours from Arequipa by sealed road.
• Aftermath published a resource estimate in March 2023 based on over 300 core and RC holes.
• Metallurgical test work is underway adding to historic work, with the goal of producing silver and copper metal and a commercial battery-grade or fertilizer-grade manganese product.

In March 2023, Aftermath published an updated resource estimate for Berenguela which included manganese in addition to substantial silver and copper resources across the Measured, Indicated and Inferred categories. Mineral Resources are stated at a cut‐off grade of 80 g/t silver equivalent. The relative value in the Mineral Resource by metal is as follows, Ag=26%, Mn=44%, Cu=26%, Zn=4%, however the estimate used pricing for agricultural grade MnSO₄ which trades at a considerable discount to battery grade manganese sulphate. The model is depleted for historical mining activities. Please refer to Aftermath Technical Report "Berenguela Mineral Resource Estimate NI 43-101 Aftermath Silver Ltd. Province of Lampa, Department of Puno, Peru", dated March 30, 2023, prepared by AMC Consultants available here or on Aftermath's website at the link below:

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.
• 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%.
