2. Consolidated Financial Results

In terms of production and sales, for all assets except Aranzazu, references herein to “GEO” are equivalent to actual gold ounces.

2.1 Total Production and Sales (GEO)

^{Notes: (1) Applies the metal sale prices in Aranzazu realized during Q4 2025: Copper price = US$5.06/lb; Gold Price = US$4,214/oz; Silver Price = US$56.86/oz and Molybdenum Price = US$22.12/oz. (2) MSG was acquired in December 2025, at which date the Company obtained control.}

Total production in Q4 2025 reached 82,067 gold equivalent ounces (“GEO”), 11% higher than Q3 2025 and 23% higher when compared to Q4 2024 at current metal prices, mainly due to negative impact from the copper-to-GEO conversion at Aranzazu. At constant prices, Aura’s quarterly production was record high, increasing by 12% compared to Q3 2025 and 29% above Q4 2024. When compared to the last quarter, the result was mainly attributable to stronger operational performance driven by higher ore processed volumes and improved grades at Almas, the production increase of Borborema and the inclusion of MSG in December.

In 2025, production reached 280,414 GEO, representing a 5% increase in current metal prices. At constant 2024 prices — which neutralize the effect of copper price fluctuations in the GEO conversion at Aranzazu — production was of 292,536 an increase of 9% over the 267,232 GEO produced in 2024, also due to Borborema production, Almas improvements and the additional of MSG. At 2025 Production Guidance Prices and excluding MSG, the 2025 production was 285,380 GEO, ending the year achieving the upper half of the Company’s 2025 Production Guidance (266k GEO – 300k GEO).

2.2. Net Revenue

In Q4 2025, the Company reported Net Revenue of US$321.6 million, representing a 30% increase compared to Q3 2025. When compared to Q4 2024, Aura’s Net Revenue increased 88%, driven by the sales increase and higher metal prices (from US$2,586/oz in Q4 2024 to US$4,090/oz in Q4 2025). Copper sale prices also contributed positively, with the average copper price increasing by 22%, from US$4.15/lb in Q4 2024 to US$5.06/lb in Q4 2025.

With this result, Net Revenues reached US$921.7 million in 2025, an increase of 55% when compared to 2024. The result was mainly driven by higher gold prices and higher production, as discussed. In 2025, average net realized prices reached US$3,446, a 49% increase when compared to 2024; and average copper prices reached US$4.51/lb, an 8% increase when compared to 2024.

2.3. Cash Cost and All in Sustaining Costs

For Q4 2025, the Company’s Cash Cost was US$1,143/GEO, representing a 3% increase compared to Q4 2024, primarily attributable to the consolidation of MSG and impact of GEO conversion from Aranzazu’s production. Excluding this impact of MSG and at constant 2024 metal prices, Aura’s Cash Cost was US$1,036/GEO, reflecting a 6% decrease compared to Q4 2024 and 2% decrease compared to Q3 2025. On a quarter-over-quarter basis, this improvement was mainly driven by operational enhancements at Almas and Borborema, supported by higher grades and higher recovery rates, respectively. On a year-over-year basis, increase in production at Almas and the additional of Borborema, which had a lower-than-average cash cost profile, contributed to the reduction.

In 2025, Cash Cost averaged US$1,136/GEO, representing a 9% increase, primarily driven by lower grades and a higher waste-to-ore ratio at Almas and Apoena, as well as the impact of copper-to-GEO conversion at Aranzazu. At constant 2024 metal prices and excluding MSG, Cash Cost in 2025 averaged US$1,054/GEO, in line with 2024 which was US$1,041/GEO. Cash Cost also adversely affected by lower stacking volumes at Minosa, resulting from higher rainfall in 2025 compared to 2024, which followed an unusually dry rainy season in Minosa during 2024, and Apoena, which is going under an investment phase. These negative impacts were offset by the addition of Borborema with its lower-than-average cash cost profile.

In Q4 2025, consolidated All-in Sustaining Cost (AISC) at current metal prices totaled US$1,521/GEO, representing a 9% increase compared to Q4 2024, while at Q4 2024 metal prices and excluding MSG would have been down 2% mainly due to higher sales volume from Almas and the addition from Borborema; these business units have the lower AISC of Aura’s portfolio of mines in production. On a quarter-over-quarter basis, AISC increased by 8% compared to Q3 2025 at current prices and 2% at constant prices ex-MSG, reflecting as flat sales were offset by temporary 18% increase in capex and 28% higher G&A, which were partially mitigated by higher production from Borborema.

In 2025, AISC reached US$1,458/GEO, an increase of 10% when compared to 2024 at current prices and 2% increase in constant prices and excluding MSG for the same reasons discussed above. At Guidance Prices and excluding MSG, Aura’s AISC was US$1,368/GEO, in line with the bottom end of the Company’s guidance range of US$1,374/GEO to US$1,492/GEO.

2.4. Gross Profit

In Q4 2025, Cost of Goods Sold (COGS) totaled US$118.8 million, representing a 21% increase compared to Q3 2025 and a 35% increase compared to Q4 2024, primarily driven by the consolidation of MSG. Excluding the impact of MSG, total COGS for the quarter would have been 7% higher than Q3 2025 and 16% higher than the same period in 2024, mainly due to the addition of Borborema into the results. For 2025, total COGS rose 13%, also driven by the results of Borborema and MSG, which represented US$49.8 million of the total. Excluding these impacts, cost versus 2024 would have been lower by around 1%, demonstrating that, under comparable conditions, the Company maintained stable costs, reflecting Aura’s disciplined cost management and operational efficiency.

In Q4 2025, disciplined cost management and significant rise of 88% in Net Revenue compared to Q4 2024, drove Gross Profit to US$203.0 million, achieving a Gross Margin of 62%. This represents an increase of 36% from Q3 2025 and 150% when compared to Q4 2024. For 2025, these same impacts were also noted, driving the Gross Profit to reach US$534.9 million, more than doubling 2024 figure, highlighting the propelled by cost containment strategies and a 55% increase in Net Revenue for the reasons discussed. In 2025 gross margin achieved 58%, 16 p.p. above 2024.

2.5. Operating Expenses

General and Administrative (“G&A”) expenses increased by 81% compared to Q3 2025, primarily reflecting: (i) payment of professional fees related to the MSG acquisition (non-recurring); (ii) the Feasibility Study for the Era Dorada Project (non-recurring); and (iii) higher stock-based compensation (non-cash) and Deferred Share Unit (“DSU”) expenses, driven by the significant appreciation in the Company’s share price during the period; (iv) declaration of commercial production from Borborema (during the pre-commercial production period, a portion of the expenses were capitalized) and (v) addition G&A associated with the MSG Mine in December 2025. Compared to Q4 2024, G&A increased mainly due to the same reasons.

In 2025, the increase in G&A expenses was driven by the same factors, as well as costs related to the Nasdaq IPO.

Exploration expenses totaled US$2.6 million in Q4 2025, a 11% increase compared to Q3 2025 and 46% decrease from Q4 2024, as most expenses related to exploration activities in the quarter were capitalized. Exploration activities in the quarter were concentrated in Aranzazu and Almas. In 2025, exploration expenses were US$8.1 million, with a total of US$3.6 million of Aranzazu and US$1.9 million of Almas, 2% higher than 2024 (excluding Projects). In 2025, Projects were significantly lower compared to 2024, which counted for US$6.4 million of Exploration expenses. In Matupá, efforts were focused on expanding reserves in regions close to X1, Pé Quente and other strategic areas. In Carajás, exploration work successfully confirmed copper mineralization, expanding the mineral potential of the region.

Other expenses primarily comprise provisions recognized to reflect the estimated partial non-recoverability of VAT credits related to Minosa ($8,250) and the expected discount on the sale of VAT (ICMS) credits from Apoena ($1,922) and other non-recurring expenses.

The Company thus ended Q4 2025 with Operating Income of US$165.1 million, compared to an Operating Income of US$67.1 million in Q4 2024, also higher compared to the Operating Income of Q3 2025 of US$136.9 million, which reflects a positive result of higher gross profit. In 2025, the Operating Income was US$458.9 million, 125% increase compared to 2024. This result occurred due to an 113% increase in the Gross Profit and a 43% reduction on exploration expenses, partially offset by 54% higher G&A.

2.6. Adjusted EBITDA

Adjusted EBITDA reached a new all-time high of US$207.9 million in Q4 2025, marking the sixth consecutive quarterly record for Aura. The Company’s increase in production, while maintaining disciplined cost control, enabled it to fully capture the benefit of rising metal prices. As a result, Adjusted EBITDA more than doubled compared to Q4 2024 and grew 37% over Q3 2025.

The year-over-year improvement was primarily driven by higher production, strong cost control and higher gold and copper prices, as discussed previously. This result was also noted on the Adjusted EBITDA margin gain of 18 p.p. compared to Q4 2024, supported by stronger metal prices but also by a 16% increase in sales volume.

In 2025, Adjusted EBITDA reached a record high of US$547.8 million, more than doubling year-over-year, representing a 105% increase compared to 2024. This strong performance was driven by higher production volumes, mainly supported by Borborema and MSG, which together added 33,334 GEO to the annual production, as well as a 5% increase in production at Almas versus 2024. Supported by operating leverage and disciplined cost management, the Adjusted EBITDA margin expanded to 59%, compared to 45% in 2024.

2.7. Financial Result

The Company’s Financial Result in Q4 2025 was a loss of US$(123.2) million, following on from the US$(102.6) million loss in Q3 2025, impacted by:

• Unrealized loss on gold hedges in Q4 2025, arising from mark-to-market (MTM) adjustments related to outstanding gold hedge positions, reflecting increase in gold prices between the start and the end of the quarter, coming from US$3,825.30 per Oz and reaching US$4,386.30 per Oz at the end of the period. In accordance with IFRS standards, the Company records MTM adjustments at the end of each reporting period for all outstanding derivative positions.

• Realized losses with gold hedges in Q4 2025 were related to cash settlement of outstanding gold collars during the quarter, driven by the expiration of gold collars within the quarter.

All of Aura’s outstanding gold collars (189,072 Ozs) are associated with the future production of the Borborema and will expire equally between January/2026 and June/2028. As previously disclosed, an estimated 80% of the production for the first 3 years of the Borborema Project were hedged in 2023 at ceiling prices of US$2,400 per Oz.

2.8. Net Income

Net income in Q4 2025 was US$(19.9) million, compared to Net Income of US$16.6 million in Q4 2024 and a Net income of US$5.6 million in Q3 2025. This result versus Q4 2024 occurred mainly due to higher financial expenses related to the MTM gold derivative losses and higher current income taxes, driven by the strong improvement in the Company’s Operating Income.

In 2025, Net Loss reached US$(79.3) million, also mainly due to mark-to-market (MTM) adjustments on open gold hedging positions, driven by the sharp increase in gold price between the start and the end of the year.

Adjusted Net Income

As result of increase in the Company’s Operating Income, Adjusted Net Income in Q4 2025 reached US$73.3 million in the period. The Q4 2025 Adjusted Net Income excludes:

• Non-cash losses related to gold hedges: US$(81.7) million

• FX losses: US$(3.3) million

• Deferred taxes over non-monetary items US$(8.1) million

As result of increase in the Company’s Operating Income, Adjusted Net Income in 2025 was US$205.7 million in the period, compared to US$81.6 million in 2024, an increase of 152%, excluding:

• Non-cash losses related to gold hedges: US$(281.5) million

• FX losses: US$(9.0) million

• Deferred taxes over non-monetary items US$14.2 million

• Loss on settlement of liability with equity instruments US$(8.8) million

3. Performance of the Operating Units

3.1 Aranzazu

^{Applies the metal sale prices in Aranzazu realized during Q4 2025 for Q3 2025 and Q4 2024: Copper price = US$5.06/lb; Gold Price = US$4,214/oz; Silver Price = US$56.86/oz and Molybdenum Price = US$22.12/oz.}

At Aranzazu, production reached 18,878 GEO, representing a 12% decrease compared to the previous quarter and 19% over the Q4 2024, resulting mainly from metal prices since higher gold prices negatively impact the conversion to GEO. At constant prices, Aranzazu production was 7% lower when compared to Q3 2025 as well as compared to Q4 2024, due to slightly lower grades of copper, silver and gold, due to mine sequencing and according to the Company’s plan. In 2025, total production decreased by 15% compared to the previous year at current prices, in line with the negative impact of the metals price conversion. At constant 2024 metal prices, Aranzazu produced 100,031 GEO, 3% above the previous year, mainly due to higher grades and commercial molybdenum production. At 2025 Guidance Prices, Aranzazu ended 2025 with a production of 92,569 GEO, in line with the Guidance range.

Aranzazu’s Net Revenue in Q4 2025 was US$66.5 million, 1% lower compared to Q3 2025 and up 26% compared to Q4 2024, primarily driven by higher metal prices. Average sales prices rose quarter-over-quarter, with copper increasing 14%, gold 21%, silver 42%. For 2025, Aranzazu’s Net Revenue reached US$246.4 million, a 25% increase over 2024, also attributed to elevated metal prices.

Cash Cost was US$1,228/GEO for the quarter, 8% higher than Q3 2025 and 25% higher than Q4 2024, mainly due to GEO conversion and also lower grades and recovery. In 2025, Cash Cost increased by 20%, with a total of US$1,156/GEO, primarily impacted by the effect of metal prices in the conversion to GEO, what was partially offset by higher grades and recovery rates.

Aranzazu’s AISC was US$1,732 in the quarter, up 15% from Q3 2025 and up 21% from Q4 2024, primarily due to variations in metal prices. At constant Q4 2024 metal prices, AISC was US$1,478/GEO, and increase of 3% over Q4 2024, mainly because of slightly lower grades of copper, silver and gold.

Aranzazu’s Adjusted EBITDA was US$41.0 million in Q4 2025, reflecting a 3% increase from Q3 2025 and a 65% compared to Q4 2024, driven by robust Net Revenue growth from higher metal prices compared to 2024. For 2025, Adjusted EBITDA totaled US$140.9 million, up 55% from 2024, propelled by the increase in Net Revenue, primarily from elevated metal prices, which more than offset the sales volume decline.

3.2 Apoena

At Apoena, production was 8,961 GEO, 3% lower than Q3 2025, driven by due to lower ore feed to the plant and lower recovery, but in line with the Company’s plan. Compared with Q4 2024, production increased 26%, primarily because of higher recovery rates, with 4% increase, and higher grades, from 0.70 g/ton to 0.79 g/ton. In 2025, production was of 35,304 GEO, a decrease of 5% when compared to 2024, attributable mainly to lower grades and lower ore mined as expected. Considering the full year of 2025, Apoena exceeded the Company’s expectations by delivering higher grades and improved productivity, achieving a recovery rate of 94%, which drove the mine to finish 2025 above the upper end of the Guidance range, which was 32,000 GEO.

Apoena’s Net Revenue totaled US$36.1 million for Q4 2025, 16% higher than Q3 2025 and 39% above the Q4 2024, driven primarily by higher gold prices.

The Cash Cost was US$1,450/GEO for the quarter, down 19% from Q4 2024, primarily driven by improved recovery rates and higher grades. Compared to Q3 2025, the Cash Cost was up 34%, mainly due to a higher waste-to-ore ratio which increased to 12.50 tonnes, combined with 29% lower ore mined volumes. For 2025, Cash Cost increased 4% to US$1,232/GEO, below Company’s annual Guidance, primarily due to lower grades, consistent with expected mine sequencing. In Q4 2025, Apoena’s AISC was US$2,427/GEO, 3% lower than Q4 2024, due to the lower G&A and decreased lease expenses. Compared to Q3 2025, AISC increased 36% due to higher maintenance costs, impacted by plant maintenance in December, representing an increase in COGS. For 2025, AISC ended with US$ 2,007/GEO, 9% higher than 2024, due to 181% higher CAPEX due to higher exploration near mine, tailing dams investments and machinery equipment. When compared to Apoena’s AISC Guidance, this result was 18% below the lower range which was US$2,425/GEO to US$2,619/GEO.

In Q4 2025 compared to Q4 2024, Adjusted EBITDA increased significantly, mainly driven by higher production levels, improved cost performance and stronger gold prices. On a quarter-over-quarter basis, despite slightly lower production and sales volumes and higher costs, the positive impact of higher gold prices more than offset these pressures, supporting an increase in Adjusted EBITDA in the quarter. In Q4 2025 versus Q4 2024, EBITDA rose by 255%, explained by the increase in production, gold prices and lower cash costs. On a full-year basis, EBITDA more than doubled in 2025 compared to 2024, primarily driven by higher gold prices, which more than offset the impact of lower production and sales volumes and higher cost levels during the period.

3.3 Minosa

In Q4 2025, Minosa production totaled 17,818 GEO, 2% lower than Q3 2025 and 8% Q4 2024, mainly due to the impact of the rainy season and expansion works to increase the stacking area. In 2025, production achieved 71,649 GEO, a decrease of 9% mainly due to lower ore feed to the plant, reflecting mine sequencing and weather-related constraints, but consistent with Aura’s expectations. This performance allowed Minosa to close 2025 at the upper end of the Guidance range.

Net Revenue totaled US$67.5 million in Q4 2025, up 14% from Q3 2025, while in Q4 2024 it grew 38%, due to the increase in the price of gold over the period. In 2025, Net Revenue reached US$230.5 million, 30% higher than 2024.

The Cash Cost was US$1,087/GEO for the quarter, down 12% from Q4 2024 and also down 9% from Q3 2025, primarily driven by lower extraction in both periods. For 2025, Cash Cost increased 2% to US$1,152/GEO, in line with the Company’s annual Guidance, primarily due to lower extraction, that negatively impacted production and sales.

The All-in Sustaining Cost (AISC) for Q4 2025 was US$1,267/GEO, down 2% from Q4 2024 with a COGS reduction of 23% driven by lower production and reduced costs. These savings were more than offset by the increase in CAPEX, which rose from US$ 0.999 million to US$ 2.253 million due to investments in leach pad phases expansion and infrastructure, in the context of a 12% reduction in sales volumes. Compared to Q3 2025, AISC decreased 8%, primarily due to lower COGS of 11% due to lower unitary mine costs and higher grades. For 2025, AISC was US$1,297/GEO, an 8% increase over 2024, reflecting the combined impact of lower sales of 11%, due to lower ore plant feed, and increase in Capex, due to improvements in pilling infrastructure.

In Q4 2025, Minosa’s Adjusted EBITDA reached US$47.9 million, up 35% from Q3 2025 and 103% from Q4 2024, driven by higher gold prices, despite reduced production from lower stacking volumes due to increased rainfall and higher CAPEX year-over-year. For 2025, Adjusted EBITDA was US$144.0 million, a 73% increase from 2024, supported by elevated gold prices and higher grades, partially offset by higher CAPEX.

3.4 Almas

During Q4 2025, Almas produced 15,872 GEO, 5% higher than Q3 2025 (15,088 GEO), driven by higher ore processed volumes and improved mine performance, reflecting the results of the plant expansion. Production was 5% lower when compared to Q4 2024, due to lower grades (decrease from 1.2g/ton to 1.02g/ton) in line with the mine sequencing. Also, as a result of the expansion project, Almas closed 2025 with production of 56,979, 5% higher than the prior year, despite lower grades due to mine sequencing. With this performance, Almas ended the year near the upper end of its Guidance.

Net Revenue was US$65.8 million in Q4 2025, up 28% from Q3 2025, driven by increased sales volumes, supported by higher ore processing from the plant expansion, and elevated metal prices. Compared to Q4 2024, Net Revenue rose 50%, primarily due to a significant rise in gold prices. For 2025, Net Revenue was US$196.0 million, a 51% increase from 2024, fueled by higher sales volumes from enhanced operational capacity and larger equipment, alongside higher metal prices.

The Cash Cost was US$837/GEO in Q4 2025, 21% higher than Q4 2024 and 15% lower than Q3 2025. Compared to Q3 2025, Cash Cost fell 15%, attributed to a production plan with a lower waste-to-ore (from 4.44 to 4.22) ratio and higher grades (up 5% from 1.01 to 1.06), while compared to Q4 2024, waste to ore ratio grew 29% with 13% lower grades. For 2025, Cash Cost increased 6% due to higher COGS.

Almas’ All-in Sustaining Cost was US$ 783/GEO in Q4 2025, down 31% from Q3 2025, supported by improved operational performance, and 10% higher than Q4 2024 due to higher Capex. Q4 2024 results were affected by positive non-recurring accounting adjustments amounting to US$136/oz. Discounting these effects, the AISC for the quarter would be US$849/oz, representing a decrease of 13% in comparison between the quarters. In 2025, Almas AISC was US$1,150/oz in line with 2024.

Adjusted EBITDA totaled US$50.7 million in Q4 2025, 66% higher than Q4 2024 result, driven by 21% increase in ore processing from the plant expansion, improved operational performance and elevated gold prices. Compared to Q3 2025, Adjusted EBITDA rose 47%, primarily due to higher gold prices and 15% lower Cash Cost and 2% lower AISC. For 2025, Adjusted EBITDA was US$132.3 million, an 78% increase from 2024, supported by higher sales volumes from expanded operational capacity.

3.5 Borborema

^{Note: Borborema’s Q2 2025 results did not presented significant sales due to the beginning of gold production on its ramp-up phase, while Q3 2025 counts with a full quarter of relevant sales. Due to this, the results of Q3 2025 and Q2 2025 are not comparable.}

Borborema’s production totaled 15,704 GEO, 54% above the previous quarter, reflecting progress along the ramp-up curve, achieving higher milling throughput, prioritizing higher-grade material, and increasing overall recovery. During the year, Borborema delivered results below the guidance range, mainly due to lower recoveries achieved during the pre-commercial production phase. This led to the decision to feed the plant with lower-grade material until full stabilization of performance. Performance improved significantly over the course of the year, and at the end of Q4 2025, recovery reached 91.7%, a significant improvement compared to the start of the ramp-up (76.5%), along with a 35% increase in grade compared to 2Q25, closing the year with an average grade of 1.42 g/t, due to mine sequencing. In 2025, the production totaled 28,500 GEO, reflecting ramp-up curve advancement, reaching higher ore throughput with a total ore plant feed of 885.8 tonnes, prioritizing higher-grade material, ending the year with an average grade of 1.19g/tonne with average recovery rate of 86%.

Net Revenue was US$65.5 million in Q4 2025, up 68% from Q3 2025, driven by increased sales volumes, supported by higher metal prices. For 2025, Net Revenue was US$108.2 million, fueled by higher sales volumes from enhanced operational capacity, alongside higher metal prices. The Net Revenue of the year was US$108.2 million, mainly because of productivity gains along the ramp-up phase, driven by fleet replacement and continued production.

The Cash Cost was US$931/GEO in Q4 2025, reflecting progress along the ramp-up curve. Borborema’s All-in Sustaining Cost (AISC) was US$1,111/GEO in Q4 2025, due to higher sales. By the end of 2025, Borborema’s Cash Cost was US$ 1,009/GEO, explained by control costs balanced with the total volume sold. The AISC of 2025 was US$ 1,175/GEO, mainly due to high CAPEX during the ramp-up phase.

Adjusted EBITDA was US$49.2 million in Q4 2025, driven by strong Net Revenue from 54% increase in production and favorable gold prices. In 2025, Adjusted EBITDA was US$ 76.5 million.

3.6 MSG

^{1. Only December 2025 considered.}

Considering the conclusion of the acquisition of MSG on December 2, 2025, Aura is consolidating MSG’s results only for the month of December, which a production of 4,761 GEO in the month. This production resulted in a Net Revenue of US$20.5 million in Q4 2025.

The Cash Cost was US$2,148/GEO in Q4 2025. MSG All-in Sustaining Cost (AISC) was US$3,132/GEO in Q4 2025. December marked the month of the change of control at MSG, and Aura is actively implementing a plan to improve production and costs throughout 2026.

7. Guidance vs. Actual

The Company achieved the 2025 Guidance, including Production, Cash Cost, All-in Sustaining Cost (AISC) and CAPEX, as shown in the results below:

The Company’s consolidated Capex for 2025 totaled US$180 million, above the high range, above the Guidance 2025 range, mainly due to:

• Expansion CAPEX: In 2025, the expansion CAPEX exceeded the Guidance Range (+6%), largely driven by advances not included in the guidance, such as: (i) the early works of the Almas Underground Development Project, and (ii) the development at Apoena exceeded plan at Nosde Pit, supporting future better production performance.

• Sustaining CAPEX: In 2025, the sustaining CAPEX was 2% above the Guidance Range, mainly due to the MSG consolidation in December, which added US$ 3.5 million in sustaining capex which had not been included in the guidance.

• Exploration CAPEX: In 2025, exploration CAPEX also exceeded guidance (+6%) following the strategy of an expanded drilling program, focused on Carajás, Serrinhas and Matupá, supporting reserve growth and long-term value creation.

2026 Guidance:

The Company’s gold equivalent production, AISC and cash operating cost per gold equivalent ounce sold, and CAPEX guidance for 2026 are detailed below.

Production

The table below details the Company’s updated GEO production Guidance for 2026 by business unit. For such Guidance, the Company considered the following metal prices:

• Gold Price = $4,287.50 /oz;

• Copper price = $5.18/lb;

• Silver Price = $58.72/oz;

• Molybdenum Price = $22.16/oz.

2026 Production Guidance:

• Aranzazu: Aranzazu’s production in 2026 is expected to be around 22% below 2025, due to the grades decrease, due to mine sequencing, assuming constant metal prices. However, given the guidance average gold price of $4,287.50 /oz, an increase of 24% over the realized gold prices of 2025, and copper price of $4.9/lb, the total volume in GEO will be impacted by an unfavorable metal-to-GEO conversion factor.

• Apoena: Apoena will focus on continuing developing a new phase of the Nosde phase III pit, as previously disclosed as part of its 2-year investment phase, to support production expansion. Compared to 2025, higher grades are expected. Production will improve, with higher production expected in the second semester.

• Minosa: Minosa is expected to maintain reliable performance throughout 2026, similar to 2025. The projected production for 2026 is lower than the previous year, mainly due to expected grade reduction during the period due to mine sequencing.

• Almas: Almas’ production is expected to reach the new installed capacity in 2026, following process optimizations and throughput enhancements implemented in 2025. These changes increased the plant’s ore processing capacity from 2.0 to 2.2 million tonnes per year. However, the full benefits will not be realized in 2026 due to lower ore grades from mine sequencing. In parallel, the Company has started developing the underground project, which—combined with additional expansion capacity this year—should drive further production increases starting in 2027.

• Borborema: With ramp-up finalized in Q4 2025, Borborema is expected to reach between 65k and 77k GEO in 2026. This guidance reflects the expected increase in Mineral Reserves driven by higher gold prices, which in turn reduces average grades compared to the original feasibility study. As a result, the Company has adjusted its mine sequencing and ore segmentation strategy to incorporate these lower-grade ores, prioritizing overall project economics and the long-term value generated by the mine

• MSG: This year’s focus is on turnaround, efficiency gains, and revisions to the mine plan and methods. This will demand greater attention to equipment maintenance and underground development. Nonetheless, aligned with our operational enhancement plan emphasizing cost optimization, we guide MSG production to 50,000–60,000 GEO in 2026. Output will ramp up quarterly in the second half, reaching higher annualized rates by year-end, with gradual improvements continuing into early 2027.

All in all, the 2026 production Guidance expects a total of 340-390 kGEO, representing an average increase of up to 85k (midpoint) when compared to 2025 at current prices and up to 89k GEO at constant metal prices.

Cash Costs

The table below shows the Company’s cash operating costs per GEO sold guidance for 2026 by Business Unit:

2026 Cash Cost Guidance:

• Aranzazu: At constant metal prices, cash costs are expected to increase due to lower grades due to mine sequencing, and mine deepening, partially offset by cost reduction initiatives (e.g., continuous miner)

• Apoena Cash costs are expected to decline slightly, driven by operational improvements in Mine and Plant and higher grades from the Nosde pit, with further improvements anticipated for 2027.

• Minosa: Cash costs are expected to rise compared to 2025, driven by lower ore grades planned due mine sequencing.

• Almas: An increase in cash cost is expected in 2026, primarily due to mine sequencing that forecasts lower ore grades and a higher strip ratio over the year as we push back the Paiol pit in 2026. Nonetheless, this increase will be partially mitigated by the capacity expansion completed in 2025.

• Borborema: Cash costs are expected to remain low and improve gradually over the year due to debottlenecking the filters’ throughput, which will add overall capacity

• MSG: Cash costs are expected to improve as operational efficiency initiatives are implemented, with benefits anticipated towards the end of the year.

All In Sustaining costs

The table below shows the Company’s all-in sustaining costs per GEO sold guidance for 2026 by Business Unit:

2026 All-In Sustaining Cost Guidance:

• Aranzazu: At constant metal prices, the increase in AISC is driven by the higher cash costs (lower FX, lower grades and mine deepening), while sustaining capex is expected to remain in line with last year.

• Apoena: AISC is expected to remain broadly in line with 2025, reflecting higher sustaining capex related to mine development, which will support improved performance in 2027.

• Minosa: In addition to higher cash costs, sustaining capex is expected to increase due to the expansion of the leach pads.

• Almas: AISC is expected to increase due to: (i) higher sustaining capex driven by continued mine development, with a higher strip ratio (from 5.0 to 8.3) as the Company advances pit opening; (ii) tailings dam capacity expansion planned for 2026, which is expected to increase the plant capacity to 3 million tons year.

• Borborema: In its first full year of operation, Borborema’s AISC is expected to be the most competitive across Aura operations. This reflects targeted investments in environmental and water management infrastructure, tailings and drainage system upgrades, and the acquisition of new filtration equipment—all aimed at enhancing operational stability and enabling potential future plant debottlenecking.

• MSG: AISC are also expected to improve as operational efficiency initiatives are implemented following the handover, with benefits anticipated to be perceived in the second half of the year.

Capex:

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

• Sustaining: Sustaining capex increases year-over-year primarily due to the full-year consolidation of MSG, which has a structurally higher sustaining capex profile (underground mine) and will demand extraordinary non-recurring investments in fleet maintenance. Additional impacts include higher mine development at Almas and a full year of production of Borborema.

• Exploration: Exploration capex is expected to increase due to an expanded exploration program aimed at growing reserves and extending mine life, as well as the incorporation of MSG into the portfolio.

• Expansion: Expansion capex increases primarily due to the Underground Project and plant expansion at Almas, 2^nd year of development of Nosde phase 3 at Apoena, early works at Era Dorada and the re-leaching project at Minosa.

Key Factors

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 of commodity prices but with continued volatility.

To decrease risks associated with commodity prices and currency volatility, the Company will continue to evaluate and implement available protection programs. For additional information on this, please refer to the 20-F.

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.
