Vancouver, British Columbia--(Newsfile Corp. - December 7, 2021) - Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (the "Company" or "Aftermath Silver") is pleased to announce that drilling has started at the Berenguela Ag-Cu-Mn project in southern Peru.

After experiencing COVID-related delays to logistics, access, and permitting, the Company has now commenced the 6,600 metre Phase 1 program focussed on the following key objectives:

  1. Metallurgical sample collection. PQ-diameter diamond core holes are planned to collect mineralized material in specific areas of the Berenguela deposit to generate three metallurgical composites (low, medium and high-grade). Selected holes will also be geotechnically logged;

  2. HQ-diameter diamond core holes for resource conversion and confirmation drilling around previous RC drill holes;

Drilling has been contracted to AK Drilling based in Lima, Peru. Drilling has commenced with a single rig, a second drill rig is scheduled to be added in the New Year.

Metallurgical samples will be shipped to Australia, where an ongoing metallurgical program is currently completing pre-concentration magnetic separation test work on low and medium grade composites made from existing core. The metallurgical program is being conducted under the supervision of leading processing and engineering firm Ausenco Limited.

"Having completed the necessary permitting and planning work, we can now focus on drilling. As we move ahead and unlock value our goal will be to demonstrate that Berenguela is one of the premier silver deposits in the Americas. I look forward to reporting on the progress as the drilling moves forward," stated Aftermath CEO, Ralph Rushton.

Rehabilitation of the existing Limon Verde core storage facility and camp is well advanced. The Company also completed a detailed survey of the site including 200 of the historic drill hole collars, and historic mine workings. Topographic surveys are also underway in the core project area using drone photogrammetry.

Community & Stakeholder Engagement

The Company is pleased to announce that a Mr. Victor Grande, a Peruvian community relations specialist has accepted the role as VP Business Sustainability and Community Relations.

Mr Grande is an experienced leader in managing social and environmental sustainability programs with more than twenty years of experience in the context of oil, gas, mining and infrastructure projects. His last role was as a senior social development specialist with the World Bank working in Bolivia, Ecuador, Peru and Chile. He has extensive field experience in socially sensitive environments working with Indigenous peoples in the Amazon and communities in the Andes.

Under Mr Grande's guidance, Aftermath's community relations team has been engaging with the local stakeholders of the Berenguela project, primarily landowners, and two agricultural associations: Cayachira and Andamarca. The initial objective of the program is to engage the local stakeholders and to solicit feedback from landowners and the agricultural associations.

Berenguela Acquisition Payments

The Company has an option to acquire a 100-per-cent interest in Berenguela through staged cash payments and work commitments under the terms of a binding agreement with SSR Mining (announced in the Company's news release dated July 27, 2020).

On July 29, 2021, SSR Mining announced that the staged cash payment stream for Berenguela was part of a portfolio of project interests and royalties sold by SSR to EMX Royalty Corp. (EMX)., hence, on November 23, 2021 the Company made a scheduled project payment of US$2.25-million to EMX as required by the July 29, 2021 sale.

Stock Option Grant

The Company also announces that it has granted 450,000 incentive stock options to consultants of the Company at a price of $0.65 cents for a period of five years. The options are subject to regulatory approval and are granted under the Company's stock option plan.

Aftermath has developed a pipeline of projects at various stages of advancement. The Company's projects have been selected based on growth and development potential.

  • Berenguela Silver-Copper project. The Company has an option to acquire a 100% interest through a binding agreement with SSR Mining Inc. The project is located in the Department of Puno, in southern central Peru. On February 25, 2021, the Company filed a NI 43-101, titled "Berenguela Silver-Copper-Manganese Property Update", available on SEDAR and on the Company's web page.

    The Company cautions that an independent Qualified Person ("QP"), as defined in National Instrument 43-101 ("NI 43-101"), has not yet completed sufficient work on behalf of Aftermath Silver to classify the estimate as a current Measured, Indicated or Inferred Mineral Resource, and Aftermath Silver is not treating the historical estimate as a current Mineral Resource. Aftermath Silver will need to validate previous work to produce a mineral resource that is current for CIM purposes.

Notes on the Berenguela Historic Mineral Resource Estimate

  • Details see Valor Resources news release dated 30 January 2018 to the Australian Stock Exchange (ASX), which summarises the results presented in report titled "Technical Report and Updated Resource Estimate on the Berenguela Project, Department of Puno - Peru, JORC - 2012 Compliance" to Valor Resources by Mr Marcelo Batelochi, independent consultant, MAusIMM Competent Person.
  • JORC 2012 definitions were followed for the Historic Mineral Resources.
  • Grades are estimated by the Ordinary Kriging interpolation method using capped composite samples.
  • Bulk density has been estimated by Nearest Neighbour method and the average value is 2.82g/cm3.
  • The Historic Mineral Resources uses a copper equivalent cut off of 0.5%, copper equivalents ("CuEq") were based on the formula CuEq (%) = Cu (%) + ((Ag (g/t) / 10000) in ounces x Ag price x silver recovery) / (Cu price x Cu recovery) + (Zn% x Zn price x Zn recovery) / (Cu price x Cu recovery). Assuming: Ag price $16.795/oz and Zn $3,150/t and recoveries of Ag 50%, Cu 85% and Zn 80%. Mn grades are not considered for CuEq calculations.
  • Numbers may not add/multiply due to rounding.
  • Challacollo Silver-Gold project. The Company has an option to acquire 100% interest in the Challacollo silver-gold project through a binding agreement with Mandalay Resources, see Company news release dated June 27th, 2019. The current CIM compliant Mineral Resource Estimate was released on December 15, 2020, the accompanying NI 43-101 Technical Report is available on SEDAR and on the Company's web page, and is summarised in Table 2.
