AFTERMATH SILVER APPOINTS CHIEF OPERATING OFFICER

Aftermath Silver Ltd. has appointed Danny Keating as chief operating officer (COO). Mr. Keating is a mining engineer with 30 years of experience in mine development, processing and project execution. His appointment strengthens the company's operational leadership as Berenguela enters a key phase of technical evaluation and derisking.

Michael Parker, a director of the company and Aftermath's current COO and qualified person, has been appointed to the role of technical director leading the Peruvian team and overseeing the exploration and development of Aftermath's Chilean projects.

Danny Keating -- chief operating officer

Mr. Keating has held senior executive roles, including chief executive officer of TSX Venture Exchange-listed Giyani Metals, an advanced manganese battery metals company, as well as leadership positions with Alufer Mining, Dynamic Mining and Australian Securities Exchange-listed Lindian Resources. He began his career with Anglo American and Gold Fields, and later worked in investment banking and corporate finance with Collins Stewart and ABN AMRO.

Ralph Rushton, president and chief executive officer of Aftermath Silver, commented:

"Aftermath is entering a transformational phase, supported by a strong balance sheet and a high-confidence silver-copper-manganese resource base. The results of our infill drilling and updated resource have provided the technical foundation to advance our engineering studies at Berenguela, an important milestone for the company and our shareholders. We expect a steady stream of news as we drill test the eastern targets and follow-up on our recent high-grade silver-copper-manganese intercepts which included 156 metres from surface grading 290 g/t Ag, 1.12 per cent Cu and 7.3 per cent manganese (see Aftermath news release dated Feb. 27, 2025). We will also be drill testing a very prospective skarn target located four km from Berenguela. Concurrently, we will be drilling at our Challacollo silver project in Northern Chile.

"Danny's appointment as chief operating officer enhances our ability to effectively execute our planned engineering studies. His experience in project evaluation, mine development and EV battery-related metals positions Aftermath extremely well as we advance the engineering work, further derisk Berenguela and demonstrate the project economics."
