AAGFFAAGFF

Aftermath Silver filed a NI 43-101 report updating the Berenguela silver-copper-manganese resource estimate in Puno, Peru, and set work for a preliminary feasibility study in 2026. The company advanced flowsheet development for silver, copper, zinc and battery-grade manganese sulphate, and secured a spot on the 2026 OTCQX Best 50 list.

1. Technical Report Filed for Berenguela Project

Aftermath Silver Ltd has submitted a National Instrument 43-101 technical report for its Berenguela silver-copper-manganese project in southern Peru. The updated mineral resource estimate outlines an indicated resource of 25.1 million ounces of silver equivalent and an inferred resource of 7.8 million ounces of silver equivalent, based on 1.2 million tonnes of contained metals. The report includes detailed block models, pit shell designs and metallurgical recovery projections of 82% for silver and 75% for copper. It also recommends supplementary test work on zinc flotation circuits and preliminary manganese sulphate leaching to support a preliminary feasibility study slated for completion in late 2026.

2. Engineering and Metallurgical Advancements Underway

Following the resource update, Aftermath Silver is advancing engineering workstreams to optimize processing flowsheets for silver, copper and zinc recovery. Pilot‐plant campaigns have begun on a combined flotation‐leach circuit, targeting 90% recoveries for copper and 85% for zinc at a pilot throughput of 20 tonnes per day. Concurrently, the company is evaluating battery-grade manganese sulphate production from tailings streams, with bench-scale tests indicating over 98% manganese extraction and potential for a 99.5% pure MnSO₄·H₂O battery precursor.

3. Recognition on OTCQX Best Market Reflects Strong Performance

In January 2026, Aftermath Silver was named to the OTCQX Best 50, a ranking of top‐performing issuers on the OTCQX Best Market. The company posted a 120% year-over-year total return, outpacing the average return of 45% among peer group companies. Trading volumes increased by 65% compared with the prior year, reflecting heightened investor interest in its Peru development story and strong operational milestones.

4. Investor Impact and Next Steps

With the Berenguela PFS targeted for year‐end 2026, investors can anticipate quarterly updates on engineering progress, metallurgical test results and potential off‐take discussions. The resource upgrade and OTCQX recognition have positioned Aftermath Silver for enhanced access to institutional capital, with management currently evaluating strategic partnerships to secure project financing for a planned 20,000 tonnes per day open‐pit operation.
