Over the last five years, resource and reserves inventory increased by 3x. LEADER IN PAYING DIVIDENDS Dividends enabled by strong cash flow generation, returning US$379 million to shareholders in dividends and buybacks since 2021 totaling a Dividend yield of 13% in 2021; 6% in 2022 and 2023, 9.5% in 2024 and 4.5% (3) in Q1 2026 LTM). DEVELOPMENT OF A HIGH - PERFORMANCE TEAM WITHIN THE AURA 360 CULTURE 1. Realized average gold price per ounce sold, net. 2. Based on the S - K 1300 Technical Report published on March 30, 2026. 3. Including share buybacks and BDRs. We calculate dividend yield as the announced dividend per share divided by the NASDAQ share price in US$ on the announcement date (dividend yield = dividend per share / share price at announcement date). The buyback yield is calculated as the total value of shares repurchased in the period divided by the average market capitalization on a given year in each case using the NASDAQ share price (buyback yield = buybacks reported / average market capitalization for a given year). The dividend yield + buyback yield is the sum of the dividend yield and the buyback yield for the reporting period. 6 operating mines, 1 project in construction, 1 in development and 1 exploration project.

We calculate dividend yield as the announced dividend per share divided by the NASDAQ share price in US$ on the announcement date (dividend yield = dividend per share / share price at announcement date). The buyback yield is calculated as the total value of shares repurchased in the period divided by the average market capitalization on a given year in each case using the NASDAQ share price (buyback yield = buybacks reported / average market capitalization for a given year). The dividend yield + buyback yield is the sum of the dividend yield and the buyback yield for the reporting period. 2.

Exploration Borborema: Unlocking Growth in the NE Corridor Strong Expansion Potential : Recent surface mapping and geophysical surveys indicate significant continuity of mineralization to the Northeast, beyond the current pit limits. High - Confidence Opportunity: Geological and magnetic anomalies confirm that the NE corridor is a priority growth zone, with drilling planned for the next exploration phases. Strategic Impact: This extension could substantially increase the resource base and extend LOM, reinforcing Borborema as a cornerstone for Aura’s long - term growth. LMP - 835 - 15 Gold Grains
