Aura Releases its Second Quarter 2021 Financial Statements and Management Discussion and Analysis and Announces Updates to its 2021 Operational and Financial Guidance

ROAD TOWN, Aug. 10, 2021 - Aura Minerals Inc. ("Aura Minerals" or the "Company") announces today that the Company has filed its unaudited interim consolidated financial statements for the quarter ended June 30, 2021, related management discussion and analysis and CEO and CFO Certificates.

In addition, the Company announces that it is also updating its gold equivalent production, cash cost per gold equivalent ounce ("GEO") produced and capital expenditure (capex) guidance for 2021, further details on which can be found in its second quarter 2021 Management Discussion and Analysis.

Rodrigo Barbosa, President & CEO, comments: "We are glad to inform the market that we are updating our production guidance at the higher end of our initial projection. It is the result of a consistent and stable production from our gold and copper assets across our multiple jurisdictions."

The Company expects improvements at its operations in the second half of 2021, as indicated below:

• EPP: the Ernesto pit is expected to be the main source of ore feed for the second half of 2021 and until 2022, with an increase in the average grade compared to the first half of 2021. The Japones pit will also be an important source of production for the rest of 2021 and, together with the Lavrinha and Nosde pits, it is expected to provide flexibility in the production at EPP with four operational pits.
• San Andres: Interruptions in the operations in July 2021 will have a negative impact on the projected production for the year, although the impact is expected to be limited. Esperanza is expected to remain the main source of ore for the rest of 2021. Improvements are expected to reduce leaching cycle in the plant and reduce average distances in the mine, increasing efficiency.
• Aranzazu: Over the first half of 2021, the implementation of improvements in the milling and flotation circuit increased throughput, with production reaching close to 100,000 tons on average per month during the second quarter. Higher production capacity throughout the entire second half of the year, combined with more favorable copper prices, is expected to have a positive impact on production and cash costs for the rest of 2021.
• Gold Road: The mine faced several challenges in the first half of 2021, including high employee turn-over, maintenance issues and other typical ramp-up challenges, all of which had a negative impact on production and cash costs when compared to the Company's expectation. Aura expects Gold Road to be more stable in the second half of 2021 and to benefit from cost reduction initiatives and will focus on continuing increasing its geological knowledge of the mine.

The comparison of the new guidance with the Company's previous guidance is detailed below.

The table below details the Company's updated GEO production guidance for 2021 by business unit:

For the updated GEO calculation for Aranzazu, the Company used realized metal prices for the January to June 2021 period and the following assumptions, based on market projection, on metal prices for July to December 2021 period: gold: US$1,801/ounce; silver: US$26.11/ounce; copper: US$4.22/pound.

The table below shows the Company's updated guidance on its estimated cash costs¹ per equivalent ounce of gold for 2021 by Business Unit:

Capex:

The table below shows the breakdown of estimated capital expenditures by type of investment for the updated guidance:

• The decrease of the Expansion Capex is mainly due to delays in the start date of construction of Almas.
• The increase in Exploration Capex is due to the shift from Exploration Expenses to Exploration Capex, as explained below.

Aura believes its properties have strong geological potential and management's objective is to expand the life of mine across its business units. Therefore, in 2021, Aura plans to invest a total of US$24 million to US$28 million (previously: US$ 24 million to US$ 28 million) which includes:

• US$ 9 million to US$ 11 million (previously: US$ 6 million to US$ 8 million) in capital expenditures (included in the table above); and,
• US$15 million to US$ 17 million (previously: US$ 18 million to US$ 20 million) in exploration expenses, not capitalized (not included in the table above).

As noted above, the Company has kept its total exploration guidance unchanged compared to the previous indication but will capitalize more expenses than previously expected. The reason is that the Company has increased its knowledge of its mineral resources and has shifted efforts to near mine exploration in some of its properties.

Key Assumptions and Factors Underlying Guidance

• The Company's future profitability, operating cash flows, and financial position will be closely related to the prevailing prices of gold and copper. Key factors influencing the price of gold and copper include, but are not limited to, the supply of and demand for gold and copper, the relative strength of currencies (particularly the United States dollar), and macroeconomic factors such as current and future expectations for inflation and interest rates. Management believes that the short-to-medium term economic environment is likely to remain relatively supportive for commodity prices but with continued volatility.
• To decrease risks associated with commodity prices and currency volatility, the Company will continue to evaluate and, if deemed appropriate, implement available protection instruments against commodity and currency markets uncertainty. For additional information on this, please refer to the AIF.
• Other key factors influencing profitability and operating cash flows are production levels (impacted by grades, ore quantities, process recoveries, labor, country stability, plant, and equipment availabilities), production and processing costs (impacted by production levels, prices, and usage of key consumables, labor, inflation, and exchange rates), among other factors.
