VANCOUVER, British Columbia, Feb. 05, 2026 (GLOBE NEWSWIRE) — Ero Copper Corp. (TSX: ERO, NYSE: ERO) (“Ero” or the “Company”) is pleased to announce record 2025 copper production and provide 2026 guidance and an updated three-year production outlook.
HIGHLIGHTS
Fourth Quarter and Full Year 2025 Results
- Optimization initiatives across the Company’s operating portfolio in 2025 contributed to record quarterly copper production of 19,706 tonnes and quarterly gold production of 13,837 ounces, representing production improvements of nearly 60% and more than 100% compared to Q1 for copper and gold, respectively.
- An additional 14,999 ounces of gold in concentrates were sold from the Xavantina Operations during Q4, the result of a year-long value-creation initiative that is expected to continue to augment gold production through mid-2027.
- Record full-year consolidated copper production of 64,307 tonnes, combined with gold production and gold from concentrate sales totaling 52,290 ounces, contributed to a quarter-on-quarter increase in liquidity of nearly $40 million. As a result, year-end liquidity totaled approximately $150 million.(1)
- In 2025, the Company completed nearly 50,000 meters of exploration drilling at the Furnas Copper-Gold Project (“Furnas”) and expects to publish the first preliminary economic assessment on the project in H1 2026. A further 50,000 meters of exploration drilling is planned in 2026 in support of accelerated engineering studies.
(1) Available liquidity as of December 31, 2025 includes approximately $105 million in cash and cash equivalents and $45 million of undrawn availability under the Company’s senior secured revolving credit facility. These financial metrics are preliminary. Audited financial metrics will be reported on March 5, 2026.
2026 Guidance
- Consolidated copper production is expected to be in the range of 67,500 to 77,500 tonnes, representing an increase of up to 20% compared to 2025. Guidance reflects higher sustained plant throughput and lower planned grades at both Caraíba and Tucumã. Consolidated C1 cash costs are expected to be between $2.15 and $2.35 per pound of copper produced.
- At the Xavantina Operations, gold production from mine operations is expected to total 40,000 to 50,000 ounces representing an increase of up to 34% compared to 2025, with C1 cash costs of $1,000 to $1,250 per ounce of gold produced and all-in sustaining costs (“AISC”) of $2,000 to $2,500 per ounce produced. In addition, gold sales from the Xavantina Operations are expected to be significantly bolstered with the continued sale of gold concentrates that commenced in Q4 2025, and which are expected to continue through mid-2027.
- Capital expenditures across the Company’s operating portfolio are expected to range between $245 and $280 million. This includes capital for additional mine ventilation, development, and equipment to support future growth at the Xavantina Operations, as well as approximately $80 million related to the continued construction of the Pilar Mine’s new shaft and ancillary infrastructure at the Caraíba Operations.
- The Company expects to spend an additional $30 to $40 million to continue advancing Furnas exploration, engineering, and permitting workstreams, and to further advance several exploration opportunities within the Company’s portfolio.
Three-Year Production Outlook
- Consolidated copper production is expected to grow over the next three years, reaching between 80,000 and 90,000 tonnes by 2028.
- At the Caraíba Operations, plant debottlenecking completed in 2025 is expected to support higher sustained throughput levels going forward, accommodating increased ore tonnage from the Surubim Mine in 2026 and from the Pilar Mine’s Deepening Extension Zone beginning in 2027.
- Copper production at the Tucumã Operation is expected to remain relatively steady through 2028, reflecting higher throughput levels, lower planned grades, and an improved stockpile management framework that is expected to reduce rehandle costs over the outlook period.
- Xavantina’s mining and processing operations are projected to deliver higher sustained production of between 50,000 and 60,000 ounces in 2027 and 2028, driven by the transition to mechanized mining and further utilization of excess plant capacity. The Company also expects sales of gold concentrates to continue through mid-2027.
“2025 marked a year of meaningful investment and transformative progress throughout the Company. We worked to strengthen our health and safety performance while executing on several key initiatives that are supporting higher sustained mining and processing rates across our operations. These efforts included the transition to mechanized mining at Xavantina, the successful completion of a multi-quarter debottlenecking effort at Caraíba and the continued ramp-up of Tucumã. The success of these programs resulted in significant quarter-on-quarter growth throughout 2025. In parallel, we completed a year-long value-creation initiative that culminated in the commencement of gold concentrate sales at Xavantina, with nearly 15,000 ounces sold in the fourth quarter,” said Makko DeFilippo, President & Chief Executive Officer.
“Looking ahead, we expect to deliver steady growth across our portfolio as we advance longer-term growth initiatives, including the new shaft at the Pilar Mine and the delivery of what will be the first preliminary economic assessment ever published on the Furnas Project. Entering 2026 with a strengthening balance sheet, combined with what we fully expect will be a record year of copper production and record gold sales – including ongoing gold concentrate sales at Xavantina – has positioned Ero’s shareholders to benefit from this historic commodity price environment.”

Record quarterly and full-year consolidated copper production reflect strong operational execution across the portfolio, including the continued ramp-up of the Tucumã Operation and the achievement of record mill throughput at the Caraíba Operations following the successful completion of a plant debottlenecking initiative during the year.
At Tucumã, production increased sequentially each quarter in 2025, with Q4 representing the strongest quarter to date, producing 9,275 tonnes of copper in concentrate, representing a quarter-on-quarter increase of approximately 22%. Higher processed copper grades during the quarter helped to offset the impact of extended downtime in December, which was related to the pull-forward of planned Q1 2026 maintenance for the early replacement of mill liners due to quality issues associated with the original equipment manufacturer. As a result, full-year production at Tucumã totaled 28,272 tonnes of copper in concentrate.
Caraíba also delivered its strongest production quarter of the year, supported by record quarterly mill throughput, which offset the impact of lower-than-planned mined and processed grades related to timing of stope sequencing, higher-than-planned operational dilution in select stopes during the quarter, and unplanned downtime in the crusher circuit that occurred late in the year. As a result, production increased 15% quarter-on-quarter to 10,431 tonnes of copper in concentrate, contributing to full-year production of 36,035 tonnes.
At Xavantina, gold production increased sequentially throughout 2025, highlighted by a significant 53% increase in Q4 compared to Q3, driven by higher throughput and grades. During the year, the operation successfully transitioned to mechanized mining, an important milestone that is expected to support higher development and mining rates going forward. While this transition resulted in a temporary step back in production in 2025 as the operation invested in the long-term productivity and safety of the mine, the impact was effectively mitigated through the successful completion of a year-long value-creation initiative that culminated in the sale of 14,999 ounces of gold in gold concentrates during Q4. As a result, gold from Xavantina, including gold from mining and processing operations as well as from gold concentrate sales, totaled 28,836 ounces in Q4 and 52,290 ounces for the full year.
2026 PRODUCTION GUIDANCE AND THREE-YEAR PRODUCTION OUTLOOK
The Company’s 2026 guidance and three-year production outlook reflect consistent growth relative to 2025. Key drivers in 2026 include higher plant throughput across the operations, supported by the Caraíba mill debottlenecking initiative successfully completed in 2025, and projected increases in throughput at the Tucumã Operation toward steady-state levels. Longer term, copper production growth is expected to be supported by planned increases in tailings filtration capacity at Tucumã and the new shaft at the Caraíba Operations’ Pilar Mine, which is expected to become operational in 2027. As a result, consolidated copper production is expected to increase over the next three years to between 80,000 and 90,000 tonnes by 2028.
At the Xavantina Operations, annual gold production is expected to increase from between 40,000 and 50,000 ounces in 2026 to between 50,000 and 60,000 ounces in 2027 and 2028, driven by higher mine production and increased mill throughput supported by the transition to mechanized mining. In addition, gold sales from the Xavantina Operations are expected to be significantly bolstered with the continued sale of gold concentrates that commenced in Q4 2025, and which are expected to continue through mid-2027.

NOTES
Alternative Performance (Non-IFRS) Measures
The Company utilizes certain alternative performance (non-IFRS) measures to monitor its performance, including C1 cash cost of copper produced (per lb), C1 cash cost of gold produced (per ounce), and AISC of gold produced (per ounce). These performance measures have no standardized meaning prescribed within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar measures presented by other mining companies. These non-IFRS measures are intended to provide supplemental information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
C1 Cash Cost of Copper Produced (per lb)
C1 cash cost of copper produced (per lb) is a non-IFRS performance measure used by the Company to manage and evaluate the operating performance of its copper mining segment and is calculated as C1 cash costs divided by total pounds of copper produced during the period. C1 cash costs comprise the total cost of production, including expenses related to transportation, and treatment and refining charges. These costs are net of by-product credits and incentive payments.
While the C1 cash cost of copper produced per pound is widely reported in the mining industry as a performance benchmark, it does not have a standardized meaning and is disclosed as a supplement to IFRS measures.
C1 Cash Cost of Gold produced (per ounce) and AISC of Gold produced (per ounce)
C1 cash cost of gold produced (per ounce) is a non-IFRS performance measure used by the Company to manage and evaluate the operating performance of its gold mining segment and is calculated as C1 cash costs divided by total ounces of gold produced during the period. C1 cash cost includes total cost of production, net of by-product credits and incentive payments. C1 cash cost of gold produced per ounce is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplemental to IFRS measures.
AISC of gold produced (per ounce) is an extension of C1 cash cost of gold produced (per ounce) discussed above and is also a key performance measure used by management to evaluate operating performance of its gold mining segment. AISC of gold produced (per ounce) is calculated as AISC divided by total ounces of gold produced during the period. AISC includes C1 cash costs, site general and administrative costs, accretion of mine closure and rehabilitation provision, sustaining capital expenditures, sustaining leases, and royalties and production taxes. AISC of gold produced (per ounce) is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplement to IFRS measures.
