Aftermath Provides Berenguela Project Update
Vancouver, BC, March 28, 2023 – Aftermath Silver Ltd. (the “Company” or “Aftermath Silver ”)
(TSX-V: AAG) (OTCQB: AAGFF) is pleased to provide an update on the Berenguela silver -copper-
manganese project in southern Peru.
On March 2nd, 2023 the Company published an updated and expanded mineral resource for the
property (see AAG News release dated March 1, 2023). Drilling in 2021-2 was in part designed to
obtain bulk (PQ diameter) core samples from various geological and metallurgical domains at
Berenguela. A comprehensive bench -test beneficiation program on selected comp osite core
samples is being designed by Kappes Cassidy of Reno, N evada, USA , focusing on optimising
processing and recoveries of silver, manganese, copper, and zinc , and on potential manganese
products including agricultural and battery grade manganese sul phate (MnSO 4). The Company
currently anticipates completion of the program in Q3/Q4 of 2023. The results will provide key
technical inputs for Aftermath's planned Preliminary Economic Analysis which is expected to
begin in late 2023.
Composite core samples, representing the key mineralized domains, are now being assembled at
the Company's core storage facility in Arequipa. The y will be shipped to KCA's facility in Reno to
facilitate pre-treatment beneficiation testing which will include ore-sorting. As a first step, initial
visual evaluations are being carried out on core samples from current and historic drilling focusing
on the distribution of various minerals and their relationship with assay grades.
Fieldwork is expected to recommence in June with exploration and mapping east of the known
mineralisation on potential extensions indicated by outcrops, historic drilling and existing
underground workings. The work will also investigate a potential intrusiv e centre to the east of
the main Berenguela mineralization.

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.
• Silver equivalency (AgEq) formula is AgEq = Ag+ Cu%*121.905+Mn%*22.809+Zn%*41.463 based on the parameters in
Table 2.
• 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%.

Geology
Mineralization at Berenguela is hosted principally in thickly bedded, folded limestones and
dolomitized limestones of mid-Cretaceous age. Several large bodies of black massive, patchy, and
fracture-controlled manganese oxide replacement mineralization occur, with associated silver,
copper, and zinc enrichment. Mineralisation is stratigraphically localised above a regional
detachment zone particularly where footwall horsts coincide with more intense folding of the
carbonate hosts.
The bulk of the mineralisation is typically preserved as eroded synform remnants, usually exposed
at surface and trending 105 -120 degrees. Mapping and resource modelling shows the
mineralisation to extend for roughly 1,300 m along strike (including a 100 m discontinuity) with a
width of 200 to 400 m. Drilling has shown the mineralisation to extend to up to 80 m below
surface where preserved.
Berenguela is interpreted as a carbonate replacement deposit (CRD) of an unusual hypogene Mn-
oxide style localised above a regional detachment zone in a low temperature, oxidising setting.
