Aura Minerals: Borborema's Momentum and Aranzazu's Strengths Drive Near-Term Upside

Aura Minerals (ARU:TSX) has delivered a strong set of Q2 2025 production results, with two key mines—Borborema and Aranzazu—providing catalysts that could propel the company toward outperforming its 2025 guidance. The first gold pour at Borborema, coupled with its on-track commercialization timeline, and Aranzazu's grade-driven production growth and cost efficiencies, position Aura as a compelling investment ahead of critical milestones in Q3 and beyond.

Borborema: A Catalyst Fully Materializing

Borborema's Q2 2025 debut was a resounding success, with its first gold pour of 2,577 gold equivalent ounces (GEO) marking the start of a pivotal growth phase. The mine is now poised to declare commercial production by the end of Q3 2025, as outlined in Aura's Q2 update. This milestone is critical for several reasons:

1. Scale and Profitability: Borborema is projected to produce an average of 83,000 ounces of gold annually over its first three years of operation, with a post-tax internal rate of return (IRR) of 41.8% at $2,600/oz gold. At full capacity, it will become Aura's second-largest mine, contributing significantly to revenue and free cash flow.
2. Cost Efficiency: As a greenfield project, Borborema benefits from modern infrastructure and lean operations. With a 11.3-year mine life and a focus on renewable energy and water recycling, the mine aligns with Aura's “Aura 360° Mining” strategy, emphasizing sustainability and operational excellence.
3. De-Risked Timeline: The project was completed in 19 months on budget and without lost-time incidents, underscoring Aura's execution capability.

Aranzazu: Operational Resilience and Grade-Driven Growth

While Borborema grabs headlines, Aranzazu's performance in Q2 2025 deserves equal attention. The mine's production rose 9% sequentially to 22,281 GEO, driven by higher ore grades and improved recoveries. This outperformance is particularly notable given the 10% year-over-year (YoY) decline in reported GEO due to rising gold prices, which skewed conversion ratios. At constant prices, however, Aranzazu's production surged 17% QoQ and 15% YoY—a clear sign of operational improvements.

Key drivers include:
- Grade Optimization: Strategic mine sequencing and exploration success in high-grade zones (e.g., the Glory Hole quarry) have boosted throughput.
- Cost Control: Aura's 2023 cash cost of $825/oz GEO (a metric likely maintained in 2025) positions Aranzazu as a low-cost asset, especially as grades improve.
- Resource Expansion: Ongoing drilling at targets like Cabrestante and Catarroyo could extend the mine's five-year life of mine, reducing reliance on external acquisitions.

Near-Term Catalysts and Long-Term Potential

Aura's Q2 results set the stage for two near-term catalysts:
1. Borborema's Commercial Production Declaration (Q3 2025): This will unlock upside to 2025 guidance, with the mine expected to contribute 33,000–40,000 ounces in its first year.
2. Aranzazu's Resource Growth: Positive drilling results in Q3/Q4 2025 could boost reserves, further de-risking the mine's long-term output.

Looking ahead, Aura's Aura 360° Mining strategy—combining operational rigor, ESG compliance, and community engagement—creates a sustainable competitive edge. With Borborema's ramp-up and Aranzazu's efficiency gains, the company is well-positioned to beat its full-year GEO guidance of 245,000–265,000 ounces, especially if gold prices stabilize or rise.

Investment Thesis: Buy Ahead of Catalysts

Aura Minerals presents a high-conviction opportunity for investors seeking exposure to a growth-oriented, operationally robust gold producer. Key reasons to buy:
- Catalyst-Driven Upside: Borborema's Q3 commercialization and Aranzazu's potential resource upgrades are near-term triggers for stock appreciation.
- Valuation Attractiveness: Trading at ~$X/oz of gold reserves (based on current metrics), Aura is undervalued relative to peers like Newmont or Barrick.
- Long-Term Growth Pipeline: Beyond Borborema, projects like Era Dorada (Mexico) and the Carajás copper project in Brazil offer multi-year expansion potential.

Risks to Consider

• Metal Price Volatility: Gold's recent fluctuations could impact GEO conversions and margins.
• Mine-Specific Challenges: Lower grades at Apoena and delays in project approvals (e.g., environmental permits for Borborema's road relocation) pose execution risks.

Conclusion

Aura Minerals is at an inflection point, with Borborema's commercialization and Aranzazu's operational resilience forming the twin engines of growth. Investors who act now can capitalize on upcoming catalysts while benefiting from the company's strong balance sheet and disciplined capital allocation. With a clear path to beat 2025 guidance and a pipeline of high-margin projects, Aura is a compelling buy for gold investors seeking both near-term momentum and long-term value creation.
