Ero Copper Corp's Tucumã Milestone: A Catalyst for High-Margin Growth and Value Creation

Ero Copper Corp's (TSX: ERO) recent achievement of commercial production at its Tucumã copper mine in Brazil marks a pivotal moment for the company. After years of investment and operational refinement, Tucumã is now positioned to deliver on its potential as a high-margin asset, while the adjacent Furnas Copper-Gold Project offers a clear path to sustained growth. For investors seeking exposure to a copper producer poised for both near-term production gains and long-term leverage to the commodities cycle, Ero Copper presents an intriguing opportunity.

The Tucumã Turnaround: Operational Momentum Takes Hold

The completion of Tucumã's third filter press and process plant modifications in June 2025 were critical steps in achieving sustained throughput levels exceeding 75% of design capacity. This milestone, declared on July 1, 2025, caps a period of operational challenges that included power disruptions and tailings filtration issues in 2024, which limited output to 5,156 tonnes of copper that year. However, the second quarter of 2025 saw a significant rebound, with total production reaching 6,400 tonnes—2,000 tonnes of which were produced in late June alone.

The improved throughput and metallurgical performance are now enabling Ero to realize its cost targets. Tucumã's C1 cash costs for 2025 are projected at $1.05–$1.25 per pound of copper—significantly below the company's consolidated guidance of $1.55–$1.80 per pound and far below the higher costs at its Caraíba operations ($2.15–$2.35/lb). This cost differential underscores Tucumã's role as Ero's profit engine, with its low-cost profile positioning the mine to generate robust margins even in a moderate copper price environment.

Furnas: The Next Growth Lever and High-Margin Opportunity

While Tucumã is the immediate focus, the Furnas Copper-Gold Project—a 60%-owned asset with Vale Base Metals—offers a compelling longer-term catalyst. Ero plans to allocate a portion of its 2025 capital budget ($80–$90 million) to advance Furnas, aiming to leverage its high-grade copper and gold resources. The project's feasibility study, expected to be completed in the next 12–18 months, could unlock a resource base that, if developed, would significantly boost Ero's production profile.

The company's three-year production outlook targets 85,000–95,000 tonnes of copper annually by 2026–2027, driven by Tucumã's full ramp-up and capital investments at Caraíba's Pilar Mine. Crucially, Furnas' proximity to Tucumã's infrastructure could reduce capital expenditures and operating costs, enhancing its economic viability.

Deleveraging and Free Cash Flow Generation: A Path to Investor Returns

Ero's financial strategy is now focused on reducing debt and converting operational improvements into free cash flow. The company's amended $200 million credit facility, extended to 2028, provides ample liquidity to fund both ongoing operations and strategic projects like Furnas. With capital expenditures projected to decline in 2025 ($230–$270 million vs. higher prior-year spending), Ero is on track to deleverage its balance sheet.

The combination of lower capital spending and higher production volumes from Tucumã should drive free cash flow generation. Assuming copper prices stabilize above $3.00/lb—a level that remains consistent with long-term fundamentals—Ero's margins could expand meaningfully. This creates a virtuous cycle where cash flow is reinvested into growth projects or returned to shareholders via dividends or buybacks.

Investment Thesis: Timing the Upside

Ero Copper's story is one of operational execution meeting strategic ambition. Investors should note three key catalysts:
1. Tucumã's Full Ramp-Up: Sustained throughput growth through 2025 will validate the mine's cost and production guidance, potentially lifting investor confidence.
2. Furnas Advancement: Positive feasibility results or a decision to proceed with development would unlock significant upside in Ero's valuation.
3. Deleveraging Progress: A reduced debt load and stronger balance sheet could attract a broader investor base, including yield-focused buyers.

The stock's current valuation appears undemanding relative to its growth prospects. At recent prices, Ero trades at roughly 5–6x estimated 2026 EBITDA, a discount to peers that may narrow as production and margins improve.

Risks and Considerations

No investment is without risk. Ero's success hinges on executing its operational plans without delays, navigating regulatory hurdles in Brazil, and managing commodity price volatility. A prolonged downturn in copper prices or unexpected cost overruns at Furnas could pressure margins and project timelines.

Conclusion: A High-Conviction Opportunity for Copper Bulls

Ero Copper's Tucumã milestone is more than a technical achievement—it's a signal that the company has turned a corner. With a low-cost asset now online, a pipeline of growth projects, and a disciplined financial strategy, Ero is well-positioned to capitalize on the global demand for copper. For investors seeking exposure to a producer with both near-term production upside and long-term asset expansion potential, Ero Copper presents a compelling entry point. The stock's valuation, operational momentum, and strategic clarity make it a standout pick in an industry ripe for consolidation and value creation.

Investors should consider Ero Copper as a core holding for portfolios focused on base metals, particularly those anticipating a sustained commodities cycle.
