ROAD TOWN, British Virgin Islands, July 21, 2020 — Aura Minerals Inc. (TSX: ORA) (“Aura” or the “Company”) today provided an update on the status of the Almas Gold Project (“Almas” or “the Project”) located in Tocantins, Brazil.

The Project is located in the state of Tocantins, Brazil. Almas consists of three deposits (Paiol, Vira Saia and Cata Funda) and several exploration targets, including Nova Prata/Espinheiro, Jacobina and Morro do Carneiro. Of these, only the three deposits, Paiol, Vira Saia and Cata Funda, have seen significant exploration work.

The Almas project was taken over by Aura early in 2018, as result of the merger of the Company with Rio Novo Gold. While studies on the Project had been previously carried out by Rio Novo (“Updated Feasibility Study Technical Report for the Almas Gold Project, Almas Municipality, Tocantins, Brazil” prepared for Rio Novo by RPM, August 9, 2016) (the “Technical Report”), Aura’s management has since been evaluating several alternatives to de-risk the Project while improving returns, focusing on reducing capex and bringing strong cash flows to the first years of operations.

Since Aura took control of Rio Novo, a series of new studies have been developed with the support of Ausenco Engineering Canada Inc (“Ausenco”) and SRK Consultores do Brasil Ltda (“SRK”). As result of such studies, the production rate was reduced from 2.0 Mt/year to 1.3 Mt/year and layout was optimized (reducing the project footprint and also reducing environmental impacts and the need to acquire large areas). There was a shift in focus regarding production, allowing the Company to target the first years on higher grades while keeping the critical process equipment, such as the grinding circuit and key infrastructure at 2.0 Mt/year to facilitate capacity increase in case additional reserves and higher grades are found.

In addition, in parallel with basic engineering a new campaign of metallurgical and milling tests taking in consideration the latest scenarios of mining plan and production scale, the Company expects to increase accuracy related to the required capex for the project and on the overall economic model and cash flow projections.

On April 30, 2020, Ausenco was officially engaged by the Company to complete a new feasibility study considering the scenario described above. Since then, Ausenco has provided an initial and preliminary “desktop study” (the “Study”), with preliminary results of the work being performed. The main results disclosed in the Study are summarized below:

  • Beginning of construction: Expected for first quarter 2021
  • Production / ramp-up phase: Expected for second/ third quarter 2022
  • Commercial production: Expected for fourth quarter 2022
  • Years in production (not considering potential for expansion in Mineral Reserves): 13
  • Preliminary production and financial estimates (ranges):
    • Annual production (first 6 years): 45,000 oz. to 52,000 oz.
    • Capex*: USD 61 million to USD 65 million
    • Pre-Tax Payback* (years): 1.1 to 1.4**
    • Pre-Tax Project NPV*: USD 219 million to USD 338 million** at 5% discount
    • Pre-Tax IRR*: 72% to 115%**
    • All-in Sustained Costs*: USD 696/oz. to USD 730/oz.

* Gold prices ranging from USD1,500/oz. to USD1,800/oz. and Exchange rates (R$/USD) from R$5.00 to R$5.50

**  This disclosure is presented on a pre-tax basis (mainly income taxes) given the preliminary nature of the Study. NPV, Payback and IRR will be adjusted accordingly to reflect the impact of taxes on the Project, the analysis of which is part of the ongoing assessment of the Study.

Currently the Company and Ausenco are working on tax implications and confirmatory metallurgical studies and milling studies

using samples representative of the initial blend from the mine in the revised production scenario, as well as starting the basic engineering work. We expect the Feasibility Study to be completed by November 2020 and construction to start in the first quarter of 2021.
