Aftermath Silver Summarises Challacollo Drill Intersections Outside of
Mineral Resource and Updates on the Challacollo Purchase Agreement
Vancouver, BC, May 20, 2021 – Aftermath Silver Ltd. (the “Company” or “Aftermath Silver”) (TSX-V: AAG)
(OTCQB: AAGFF) is pleased to provide a summary of the ongoing drill core sampling program and other
drill intersections at its Challacollo Silver-Gold project in northern Chile. These intersections are outside of
November 2020 Mineral Resource domains, but within the optimised pit shell used to define the material
types in the current NI 43-101 compliant Mineral Resource estimate.
The 2020 Mineral Resource estimate incorporated sub-parallel veins into the Challacollo estimate for the
first time . I mportantly approximately 84% of the Indicated and Inferred Mineral Resources are now
constrained by an optimised open pit shell. This allows the Company the opportunity to investigate lower
grade material and second order high grade veins within that pit shell.
Mineralised Stockwork / Breccia - While the higher grade epithermal mineralised structures at Challacollo
are able to be recognised visually there are large portions of mineralised stock work / breccia that are less
obvious and were not the focus of previous operators , as a result the mineralised breccia has not been
consistently sampled. To improve the interpretation of the mineralising system in the hangingwall within
the current optimised pit shell the Company has sought to undertake a program of sampling the
unsampled historic core. To date approximately 60% of that sampling program is complete. Table 1 below
summaries these results and other historic results for mineralisation outside of the current Mineral
Resource but within the optimised pit shell that constrains the current Mineral Resource, a strike length
of 1.8 km, see Figure 1. These lower grade zones could potentially be processed using heap leach methods,
that would be run in parallel with the agitated leach flow sheet envisaged for the high grade current
Mineral Resource.
Second Order High Grade Veins - There are also numerous previously unreported intersections in second
order high grade vein structures that were not incorporated into the Mineral Resource due to a lack of
drill density in the hangingwall . These higher -grade vein intersections , again, outside of the current
Mineral Resource but within the optimised pit shell are also summarised in Table 1.
Ralph Rushton, President and CEO of the Company, commented “The opportunity to potentially develop a
parallel lower grade heap leach project from the breccia mineralisation is an important increment to the
project, this material would otherwise be mined as waste in a n open pit. The potential to develop the
second order higher grade veins will be investigated with the infill component of the drill programs that
will be announced shortly.”
Additional drilling will be required to develop a mineral resource on both the second order higher -grade
veins and the lower grade breccia intervals. No metallurgical testwork has been performed on the lower
grade mineralisation. As a first step, diagnostic cyanide leach test work will be performed on composites
selected from the 2021 sampling program when sampling is complete. Details of the metallurgical
testwork on higher grade vein / structure mineralisation can be found in the November 2020 Challacollo
Technical Report, an average of 92% for Silver and 75% for Gold was adopted for the Mineral Resource
estimate cut off determination.
The core sampling program is currently suspended in accordance with COVID-19 restrictions in Chile. Work
will resume as soon as its permissible and safe to do so.

Table Notes: All results in Table 1 are rounded. Assays are uncut and undiluted. Widths are drilled widths, not true
widths, as a full interpretation of the actual orientation of mineralization outside of the Mineral Resource is not
complete. Intervals with breccia style mineralisation were chosen based on a 35 g/t Ag cut-off with no more than 1
m of internal dilution and a minimum intersection length of 2 m. Intervals with vein /structure mineralization were
based on a 100 g/t Ag cut -off with no more than 1 m of dilution. For a discussion on sample preparation, quality
assessment and control see below.
Update on Challacollo Share Purchase Payments
The Company would like to advise that it has exercised its option to split the fourth and final payment for
Challacollo into two payments. Aftermath also elected to make the first of these payments, C$3 million, in
the form 50% cash and 50% in Aftermath common shares. A total of 2,055,000 common shares were issued
to Mandalay on May 5 th, 2021. The TSX Venture Exchange required this payment to be characterized as
“shares for debt”.
By opting to issue shares for a portion of this payment, the Company will be able to direct an additional
$1,500,000 towards its exploration programs in 2021. The Company now has approximately $12,500,000
in its treasury, and is well-funded to advance its 2021 exploration and development programs.
The final payment of CA$3,000,000 to earn 100% of the Challacollo is now due on April 30, 2022, prior to
which the Company may again elect to pay this 50% in cash and 50% in Aftermath common shares.

Technical Information on Sampling and Assaying
Diamond holes DCH-07A, 09 and 11, were drilled HQ3 core size. Both of these series of holes were drilled
by Mandalay in 2014, but were not sampled over these intervals . These form part of Aftermath’s 2021
core sampling program.
Aftermath sampled the core on minimum 0.6 m to a maximum of 1.5 m lengths, to match geological
boundaries, the average sample length was 1 m . T he core was cut in half using a diamond saw. The
unsampled core was returned to the core box and stored at the Challacollo core yard. The half core sample
was shipped to ALS laboratory in Copiapó, under the supervision of Aftermath field staff, for sample
preparation. ALS then dispatch pulps to the ALS laboratory in Lima, Peru for 32 element ICP analysis using
ALS code ME-ICP61a, 50 gram fire assay with gravimetric finish for silver, ALS code Ag-GRA22, and 50 gram
fire assay for gold with atomic absorption spectrometry finish, ALS code Au-AA24.
The Company's QA/QC program monitors sample preparation and analysis. Two c ertified reference
materials and one blank are inserted into the normal core sample sequences every 20 core samples, (i.e.,
after the 20th core sample 2 CRMs and 1 blank follow, for a total of 23 samples). The qualified person (QP)
has analysed the results of the CRM’s and blanks and assessed that they do not show any significant
contamination during sample preparation or analytical bias.
Diamond holes DCH-13 to DCH-36, drilled HQ3 core size, were drilled and sampled by Mandalay in 2014.
The QA/QC program included the insertions of CRM’s and blanks into the sample stream and umpire check
repeat assays at different laboratories. The QP has analysed the results of the CRM’s and blanks and
assessed that they do not show any significant contamination during sample preparation or analytical bias.
Drill holes prefaced with “CHAG” were drilled by and sampled by Silver Standard between 2002 and 2003.
QA/QC program for this series of holes included field duplicates submitted as a separate batch, while no
CRMs or blanks were used for these holes . The QP has assess the umpire assaying verifies the accuracy
between labs, however in the absence of CRMs and blanks the QP can’t assess contamination that may
result during sample preparation.
RC holes DTH-CH-01 and 07 were drilled and sampled by Mantos Blancos in 1996. DCHMT-01 and 03 were
drilled PQ3 core size by Mandalay in 2014. No QC data is available for the “DTH-CH” and “DCHMT” holes,
the QP has not completed sufficient work to verify the historic information for these drill intersections.
Further details of the sample preparation and QA/QC for holes DCH -13 to 36, and holes prefaced
“DCHMT”, “CHAG” and “DTH-CH” can be found in the current NI 43-101 compliant Challacollo Technical
Report, titled “Challacollo Silver-Gold Mineral Resource Estimate” with an effective date of December 15,
