Aftermath Silver's Berenguela Metallurgical Testwork Yields High Silver Recoveries

Vancouver, British Columbia--(Newsfile Corp. - October 16, 2024) - Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (the "Company" or "Aftermath Silver") is pleased to provide an update on recent metallurgical studies at the Company's Berenguela Silver-Copper-Manganese project in southern Peru ("Berenguela").

The results show a recovery of 95% silver and 89% silver respectively for the 2 composites tested. The standard leach process shows no interference from manganese or other metals. Cyanide consumption is less than 1 kg per oz of silver recovered, indicating this is not a significant cost or technical issue. Test work to complete the flowsheet details on Aftermath's Berenguela project is continuing at Kappes Cassiday and Associates' (KCA) Reno facility. Recent work has focused on silver extraction from two composite samples RD2MINA (KCA test 100164) and RD4LOWA (KCA test 100166). Work is continuing on additional composite samples of mineralization.

Michael Williams, Aftermath's Executive Chairman commented: "We are extremely pleased with the metallurgical results to date, as we have demonstrated that we can potentially produce a battery grade manganese sulphate product and the recoveries of the silver and manganese to date are high. As we move into the next phase of our metallurgical test work, we look forward to scaling up the work. The next stage of our metallurgical test work is advancing and includes preliminary process and sizing studies for plant design purposes."

The basic flowsheet involves acid leaching of the mineralization using sulfuric and sulfurous acids to dissolve Cu, Mn, Fe, and Zn, then purifying this solution with the objective of producing silver, copper and High Purity Manganese Sulfate Monohydrate (HPMSM). Flowsheet steps to accomplish this have been completed, and HPMSM has been made from three ore composites which represent over 65% of the resource. The acid leach processes dissolve less than 1% of the silver in the mineralization hence the tailings from the acid leach process will be sent to a standard cyanide leach plant.

The current test program builds on metallurgical work carried out by KCA in 2010. Details of the historic test flowsheets and results are summarized in Section 13 of the 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:

Sixteen composite samples weighing over 6 tonnes in total were selected from Aftermath's metallurgical drilling program and delivered to KCA's laboratory in Reno. The composites represent the key geometallurgical domains which cover all mineralization types encountered and form the basis of the current metallurgical processing campaign. Test work is being performed individually or on blends of the samples.

Warrants

The Company is also pleased to announce that 6,535,487 of its outstanding warrants to purchase common shares of the Company have been exercised since June 1, 2024 for cash proceeds to the Company of C$1,795,453. The Company intends to use the net proceeds to complete geological, metallurgical and engineering studies at the Company's Berenguela Silver-Copper-Manganese project in southern Peru and for general working capital purposes.

Stock Option Grant Correction

The Company wishes to clarify disclosure in its press release dated September 4, 2024 announcing the granting of stock options ("Options") and restricted share units ("RSUs") to purchase common shares of the Company to certain officers, employees and consultants pursuant to the Company's stock option plan.

The Company granted a total of 5,275,000 stock options ("Options") -not 5,025,000 as originally stated- to purchase common shares of the Company to certain officers, employees and consultants pursuant to the Company's stock option plan. Such options are exercisable into common shares of the Company at an exercise price of Cdn$0.35 per common share for a period of five years from the date of grant. The stock options are subject to regulatory approval, will vest over a period of twelve months and are granted under the Company's stock option plan.

The Company issued restricted share units ("RSUs") to certain directors, officers and employees of the Company in accordance with the Company's Restricted Share Unit Plan ("RSU Plan"). The vesting terms in the September 4, 2024 news release should have stated that the RSUs vest 1/3 after 12 months from the date of the grant and 1/3 annually thereafter and will fully vest on the date that is three years from the date of grant. Once vested, each RSU represents the right to receive one common share of the Company or the equivalent cash value thereof, at the Company's discretion.

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 Mineral 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.
