Mergers & Acquisitions

FOR IMMEDIATE RELEASE August 1, 2018

(AAG2018 – NR # 03)

Execution of Non-binding Letter of Intent to Purchase the Advanced

Challacollo Silver – Gold Project, Chile

Vancouver, BC – 1 August, 2018 - Aftermath Silver Ltd. (AAG.H – TSX-V) (“Aftermath” or

the “Company”) is pleased to announce it has entered into a non-binding Letter of Intent (the

“LOI”) with Mandalay Resources Inc . (“ Mandalay”) to purchase the Challacollo silver-gold

project (“Challacollo” or the “Project”) through the purchase of 100% of Mandalay’s shares in the

Chilean holding company Minera Mandalay Challacollo Limitada (“MMC”) , which currently

owns 100% of the Project. Challacollo is the only asset held by MMC.

Challacollo is a low sulphidation epithermal dep osit which hosts an historic Mineral

Resource of Indicated of 4.7 million tonnes at 200 g/t silver and an Inferred of 1.6 million

tonnes at 134 g/t silver, with associated gold credits. Drilling has defined the historic mineral

resources on the principal vein (Lolón Vein) to a depth of approximately 200 m below surface, the

Company will focus efforts on parallel vein systems, not included in the mineral resource that have

some preliminary drilling.

Mr. Sean Hurd, President and CEO of the Company, commented “The acquisitions of the high

grade Challacollo project and the recently announced Cachinal silver -gold project drives

Aftermath into the upper ranks of silver dominant developers, with pro-forma total silver ounces

of 48.6 million tonnes Indicated Mineral Resources at 146 g/t and 9.9 million tonnes Inferred

Mineral Resource at 128 g/t . The Company believes both projects have significant upside

potential and will now prepare plans to drill both projects. The Company has focused efforts on

Chile, a highly ranked mining jurisdiction, which the Company believes provides significant

advantages over other Latin American countries but has been overlooked for its silver potential in

recent years.”

Material Terms of the Acquisition

The Company will pay Mandalay the following consideration for MMC:

• CA$1,000,000 cash on the closing date;

• CA$1,250,000 cash not later than the 18 months following the closing date; and

• CA$1,500,000 cash upon the first to occur of (i) completion of a NI 43-101 technical report

of either a mineral resource of not less than 50M silver equivalent ounces, (ii) a NI 43-101

feasibility study and (iii) 18 months from the date of granting of the Environmental

Assessment Decision (“Resolución de Calificación Ambiental”) associated with the

environmental assessment process that is currently in progress for the execution of a

drilling campaign at the Project;

• CA$7,875,000 cash or the equivalent value in Aftermath shares (based on the trading price

of Aftermath shares at the time of the payment) not later than November 30, 2019, provided

that in no event shall the number of Aftermath shares issued represent more than 49% of

Aftermath’s outstanding shares following such payment.

The closing of the acquisition is subject to a number of conditions precedent, including execution

of a definitive agreement, approval of the Acquisition by the shareholders of Aftermath, and TSX

Venture Exchange approval and the receipt of all necessary third party consents.

In connection with the acquisition, Aftermath will assume Mandalay’s existing contingent share

and silver delivery payment obligations with respect to the Project under the terms of a share

purchase agreement dated December 19, 2013 among Silver Standard Resources Inc. (“SSRI”),

Silver Standard Ventures Inc. (“SSVI”), Mandalay and Mandalay Resources (Chile) SPA and

other existing royalties.

In connection with the acquisition, Aftermath and Mandalay will enter into an investor rights

agreement pursuant to which Mandalay will have the right to participate in future equity offerings

by Aftermath in order to maintain its pro rata ownership interest and, for as long as Mandalay

owns at least 10% of Aftermath’s outstanding shares, to nominate one member of Afterm ath’s

board of directors. Aftermath will have a right of first refusal to direct the disposition of any

Aftermath shares that Mandalay proposes to sell for as long as Mandalay owns at least 20% of

Aftermath’s outstanding shares.

finder’s fee is subject to TSX-V rules and limitation ranges and will be paid in cash and shares.

Overview of the Challacollo Silver-Gold Project

The following information (and other historic mineral resource information set out in this press

release with respect to the Project) is based on a technical report in respect of the Project prepared

for MMC by Mining Plus entitled “NI 43-101 Technical Report for the Challacollo Silver Project,

Region 1, Chile” and dated March 31, 2015 (the “Mining Plus Report”). The Mining Plus Report

is available under Mandalay’s SEDAR profile at www.sedar.com. A n independent “Qualified

Person”, as defined in National Instrument 43-101 (“NI 43-101”), has not done sufficient work on

behalf of Aftermath to classify the historical estimate as a current indicated mineral resource or

inferred mineral resource, and Aftermath is not treating the historical estimate as a current mineral

resource. Further work must be completed in order to demonstrate whether a reasonable

expectation for commercial extraction exists. The mineral resource estimate is a historical estimate

and should not be relied upon.

The Challacollo Silver-Gold Project is located in Chile’s Tarapaca R egion (Region I), 130 km

southeast of the major port city of Iquique and 50 km south of the town of Pica. The project is

located approximately 30 km east of the Pan American Highway, via Teck Resources ’ Quebrada

Blanca Copper Mine access road, before turning onto a gravel track for 20 km. Travel time from

Iquique airport is 1.5 hours.

Power transmission lines are located 15-30 km from the property, in part to service nearby mines

of Collahuasi and Quebrada Blanca. The Project includes water rights.

Silver-gold-zinc mineralization at Challacollo occurs in a cluster of sub-parallel, low-sulphidation

epithermal quartz veins and brecciated structures hosted in the Late Cretaceous Challacollo

Volcanic Complex comprising rhyolites of various types. There a re four main north to northeast

trending veins that pinch and swell following north-south trending faults in the property area - the

Lolón, Palermo, Gladys 4, and Gladys 1. Most of the previous exploration and mining activities

on the Property have been ca rried out on the Lolón Vein, the Mineral Resource estimate (see the

Table above) includes only the Lolón vein.

Mining has occurred at Challacollo since 1770, principally from 1896 to 1931 when low silver

prices resulted in closure. Illegal artisanal miners were mining intermittently up to 1980 when the

then owner reasserted legal claims and mined until the early 1990’s. Modern exploration has

occurred in several programs starting in 1995. The underground drives were accessed and sampled

by Silver Standard in 2001 and Mandalay in 2014.

The oxidation level bottoms at approximately 200 m below surface; however, the down dip extent

of the mineralized structures remains unknown. Gold and base metal grades increase at depth.

Notes on the Mineral Resource Estimate set out in the Mining Plus Technical Report:

• The Mineral Resource has been prepared by independent qualified persons Marek Mroczek

P.Eng., Michael Collins, P.Geo., Seam Butler, P.Geo., of Mining Plus Canada Consultants

Ltd and Juan Carlos Tapia of Sedgman S.A., with an effective date of December 31, 2014.

• Mineral Resources stated according to CIM guidelines.

• Mineral Resources are estimated at a cut-off grade of 60 g/t Ag.

• Mineral Resources are estimated using a silver price of US$24/oz, a gold price of US$1,400

per ounce, metallurgical recoveries of 92% for silver and 75% for gold, and operating costs

of US$50 per tonne.

• A density of 2.45 g/cm3 is used as a base density with adjustments according to the

variation of the estimated barium, lead and zinc grades.

• No capping of Ag grades has been applied due to low grade variability. Au grades have

been capped at 3 g/t for two sample composites 4.57 g/t Au and 4.11 g/t Au respectively.

• QA-QC details can be found in the NI 43-101 Technical Report, filed under Mandalay

Resources profile on SEDAR.

• To the knowledge of Aftermath Silver, there is no new data available since the calculation

of the above historical resource estimate and no additional work has been done to upgrade

or verify the historical resource estimate;

Private Placement

The Company previously announced an equity financing of not less than C$5 million (the

“Financing”) to fund transaction costs of the Cachinal, this has been increased to C$7 million to

fund the acquisition of MMC and initial exploration expenditures on the Project. The terms of the

Financing will be determined in the context of the market and will be announced at a later date.

Completion of the Financing is subject to acceptance by the TSX Venture Exchange.
