Ero Copper Corp.'s Furnas Project: A Strategic Catalyst for Copper-Gold Sector Growth

In an era where global demand for copper and gold is surging due to decarbonization and technological innovation, Ero Copper Corp. (TSX: ERO) has positioned itself as a compelling player in the copper-gold sector through its Furnas Project in Brazil. The project, located in the prolific Carajás Mineral Province, has recently achieved critical exploration milestones that underscore its potential to become a long-life, high-grade operation. These developments, coupled with strategic partnerships and robust resource estimates, make Furnas a standout asset in a sector poised for structural growth.

Strategic Exploration Milestones: Deepening the Resource Base

Ero's Phase 1 drill program, completed in early 2025, extended mineralization at Furnas to depths of approximately 950 meters down-dip from the surface, far exceeding historical drilling limits of 580 metersEro Copper Intercepts 115 Meters at 0.98% CuEq¹ in Deepest Hole Drilled to Date at Furnas Copper-Gold Project^[1]. Notably, the deepest hole drilled to date, FURN-DD-00322, intercepted 115 meters at 0.98% copper equivalent (CuEq), including high-grade intervals such as 46 meters at 1.11% CuEq and 28 meters at 1.25% CuEqEro Copper Files Technical Report for the Furnas Copper-Gold Project^[2]. These results, along with 103 meters at 1.26% CuEq in the Southeast zone (FURN-DD-00305) and 115 meters at 0.60% CuEq in the Northwest zone (FURN-DD-00321), demonstrate exceptional continuity and down-dip potentialEro Copper Announces Initial NI 43-101 Mineral Resource Estimate for the Furnas Copper-Gold Project^[3].

The Phase 1 program, which exceeded 28,000 meters, has already laid the groundwork for an updated National Instrument 43-101 (NI 43-101) compliant resource estimate and a preliminary economic assessment (PEA). The PEA, expected by mid-2026, will provide critical insights into the project's economic viabilityEro Copper Intercepts 115 Meters at 0.98% CuEq¹ in Deepest Hole Drilled to Date at Furnas Copper-Gold Project^[4]. Meanwhile, the Phase 2 drill program (17,000 meters) is on track to conclude in early Q4 2025, three months ahead of schedule, further expanding the resource baseEro Copper Corp. | Furnas Project^[5].

Resource Potential: A Deposit with Long-Life Prospects

The initial resource estimate as of June 30, 2024, indicated 35.2 million tonnes of indicated resources and 61.3 million tonnes of inferred resources, both grading 1.36% CuEqEro Copper’s High Growth and Return Potential Bolstered by Furnas Project Prospects^[6]. With the recent deep-dip drilling results, Ero anticipates a significant upgrade to these figures. Analysts highlight that the project's potential to host over 1 million tonnes of copper and 2 million ounces of goldEro tables resource estimate for Brazil copper-gold project^[7] aligns with the industry's demand for large-scale, high-grade deposits.

The proximity of Furnas to Ero's existing Tucumã Operations and Vale Base Metals' Salobo mine also enhances its logistical and economic appeal.

Strategic Partnerships and Financial Discipline

Ero's partnership with Vale Base Metals, under a definitive earn-in agreement, further de-risks the project. Vale's involvement provides technical expertise and financial backing, with Ero set to acquire a 60% interest upon meeting exploration milestonesEro Copper Announces Initial NI 43-101 Mineral Resource Estimate for the Furnas Copper-Gold Project^[9]. This collaboration mirrors successful models in the sector, where junior explorers leverage major partners to scale projects efficiently.

Financially, Ero has maintained a disciplined approach, balancing exploration spending with debt management. The company's recent debt refinancing and strong cash reserves position it to fund the PEA and subsequent development phases without diluting shareholdersEro Copper Files Technical Report for the Furnas Copper-Gold Project^[10].

Future Outlook: A PEA-Driven Catalyst

The upcoming PEA, due in mid-2026, will be a pivotal moment for Ero. Preliminary data suggests the potential for an underground mine with a multi-decade lifespan, leveraging Ero's expertise in Carajás. If the PEA confirms robust economics, the project could attract further investment or even a strategic acquisition, given the sector's current appetite for high-grade assetsEro Copper Intercepts 115 Meters at 0.98% CuEq¹ in Deepest Hole Drilled to Date at Furnas Copper-Gold Project^[11].

Conclusion: A High-Conviction Play in a Critical Commodity

Ero Copper's Furnas Project exemplifies the intersection of strategic exploration, resource potential, and sector tailwinds. With its deep-dip mineralization, proximity to infrastructure, and strong partner support, Furnas is well-positioned to become a cornerstone of Ero's growth strategy. For investors seeking exposure to the copper-gold sector, the project offers a compelling case of value creation through disciplined execution and geological promise.
