Ero Copper delivered a standout 2025, with record copper production of 64,307 tonnes from its Caraíba and Tucumã operations and total gold output from Xavantina of 52,290 ounces including concentrate shipments. Stronger volumes and higher metal prices drove revenue to $785.8 million and cash flow from operations to $395.1 million, up 172% year-on-year. Adjusted EBITDA nearly doubled to $409.7 million and net income swung to $266.9 million from a prior-year loss, with net debt/adjusted EBITDA improving to 1.2x. Tucumã reached commercial production on July 1, 2025 and posted low C1 cash costs of $1.69 per pound in its first commercial period, while Caraíba and Xavantina completed key debottlenecking and mechanization initiatives. The company ended the year with $150.4 million of liquidity and outlined 2026 guidance targeting up to 77,500 tonnes of copper and 50,000 ounces of gold, alongside $275–$320 million of planned capital spending and a positive preliminary economic assessment for the Furnas copper-gold project.
Ero Copper reported a strong 2025, with record copper output and a sharp swing back to profitability. Total copper production reached 64,307 tonnes, up from 40,600 tonnes in 2024, supported by ramp-up at Tucumã and record throughput at the Caraíba Operations. Gold production from Xavantina was 37,291 ounces, with an additional 14,999 ounces shipped in concentrate, bringing total gold from the operation to 52,290 ounces.
Revenue grew to $785.8M versus $470.3M in 2024, while net income rose to $266.9M from a loss of $67.8M. Adjusted EBITDA reached $409.7M, and operating cash flow was $395.1M, helping lift year-end cash to $105.4M and available liquidity to $150.4M, with net debt at $501.7M.
For 2026, Ero guides consolidated copper production of 67,500–77,500 tonnes and gold production of 40,000–50,000 ounces, with copper C1 cash costs targeted at $2.15–$2.35 per lb and gold AISC of $2,000–$2,500 per oz. The company plans $275–$320M of capital expenditures across Caraíba, Tucumã, Xavantina and the Furnas Copper-Gold Project, where a preliminary economic assessment outlines a large-scale, 24‑year mine life with an after-tax NPV (8%) of $2.0B and 27.0% IRR.
Ero Copper filed a Form 6-K to share the inaugural Preliminary Economic Assessment for its Furnas Copper-Gold Project in Brazil, outlining a large-scale, long-life operation. The study envisions a 24-year initial mine life with a centralized 13.5 Mtpa plant fed by selective open pits and two underground mines in the Southeast and Northwest zones.
Over the first 15 years, the PEA targets average annual production of about 108,000 tonnes of copper equivalent, including 70,000 tonnes of copper, 111,000 ounces of gold and 532,000 ounces of silver. Life-of-mine output totals over 1.2 million tonnes of copper, roughly 2.0 million ounces of gold and 9.0 million ounces of silver.
At long-term prices of $4.60/lb copper, $3,300/oz gold and $40.00/oz silver, the Project shows an after-tax NPV (8%) of $2.04 billion, a 27.0% after-tax IRR and a 3.1-year payback, with life-of-mine C1 cash costs around $0.30 per pound of copper produced and initial capital of $1.28 billion. At higher metal price assumptions of $6.10/lb copper and $5,550/oz gold, after-tax NPV (8%) increases to $4.7 billion and IRR to about 44.0%.
The PEA is preliminary and based on mineral resources, not reserves, and includes inferred resources that do not have demonstrated economic viability. Furnas is being advanced under an earn-in agreement with Vale Base Metals, under which Ero can earn a 60% interest by completing staged drilling and engineering milestones leading up to feasibility-level studies.
