Aftermath Silver Completes Acquisition of Remaining 20% of Cachinal Silver Project, Chile

Vancouver, May 26, 2021 - Aftermath Silver Ltd. (TSXV: AAG) (OTCQB: AAGFF) (the "Company" or "Aftermath Silver") is pleased to announce that it has completed the acquisition (the "Acquisition") of SSR Mining Inc.'s ("SSR") 20% interest in Minera Cachinal S.A. ("Minera Cachinal"), the Chilean holding company for the Cachinal Ag-Au project (the "Cachinal Project"). The Acquisition was previously announced on May 27, 2020. Completion of the legal documentation in Chile, which was delayed by issues related to the COVID pandemic, has now taken place.

Aftermath and SSR previously signed a purchase agreement covering Aftermath's acquisition of SSR's 20% interest in the Cachinal Project for a total consideration of C$700,000. The final stage of the transaction was the recent completion of the relevant Chilean documentation and registration of Aftermath's ownership of Minera Cachinal - which owns the Cachinal Project- with the Chilean authorities. Aftermath Silver now owns 100% of the shares of Minera Cachinal, minus one share which will remain held by Aftermath's Chilean legal counsel, as per Chilean business law requirements.

Michael Williams, Executive Chairman of Aftermath said: "We're pleased to finalise this transaction and secure Aftermath's ownership of Cachinal. I'd like to thank our Chilean legal counsel for helping to expedite this transaction despite challenges poised by COVID protocols. We can now advance our exploration and development plans which we will be announcing shortly."

The Cachinal Project is located in Chile's Antofagasta region (Region II). The project is located about 40 kilometres east of the Pan American Highway, in a nearly flat plain at an elevation of around 2,700 m above sea level, 16 km north of Austral Gold's Guanaco gold-silver mine. On September 16, 2020, Aftermath announced a NI 43-101 compliant, current Mineral Resource estimate for the Cachinal Project which can be found on the Company's website (https://aftermathsilver.com/projects/technical-reports/) and on its SEDAR profile.
