The initial mineral resource estimate highlights significant potential for the Project. At a 1.00% copper equivalent ("CuEq") cut-off grade, the mineral resource estimate, effective June 30, 2024, totals:
This estimate is supported by more than 90,000 meters of historic drilling on the Project, conducted by Vale S.A. and Anglo American plc, as well as a resampling and database validation program undertaken by the Company.
"We are extremely pleased with this initial mineral resource estimate for Furnas. It provides a solid foundation upon which we can focus, over the coming months, on unlocking further potential," said David Strang, Chief Executive Officer. "Our Phase 1 drill program will target two key objectives: improving the definition of high-grade zones through infill drilling and extending known mineralization within these zones beyond the historically drilled depth of approximately 300 vertical meters from surface.
"Furnas presents a tremendous opportunity to define a major copper-gold mineral resource capable of supporting a large-scale underground mine. Our experience in underground mining in Brazil, coupled with the successful construction of our new Tucumã mine and processing plant in the Carajás, positions us well to advance this Project.
"Together with our partners at Vale Base Metals, we are committed to progressing Furnas in a manner that delivers sustainable benefits for all stakeholders and reinforces Brazil's position as a global leader in the responsible, low-carbon production of critical minerals."

In September 2024, the Company received drilling permits from the Pará State environmental agency, allowing for the commencement of the Phase 1 drill program in October 2024. This minimum 28,000-meter program will focus on two identified high-grade zones – the NW and SE Zones – within the broader deposit. The program is designed to support a preliminary economic assessment on the Project. The drill plan comprises:
FURNAS COPPER-GOLD PROJECT DETAILS AND EARN-IN AGREEMENT
Furnas is an iron oxide copper-gold deposit located approximately 50 kilometers southeast of Vale Base Metal's ("VBM") Salobo operations and approximately 190 kilometers northeast of Ero's Tucumã Operations. Covering an area of approximately 2,400 hectares, the Project sits within fifteen kilometers of extensive regional infrastructure, including paved roads, an industrial-scale cement plant, a power substation and Vale S.A.'s railroad loadout facility.
In July 2024, the Company signed a definitive earn-in agreement ("Agreement") with Salobo Metais S.A, a subsidiary of VBM, to earn a 60% interest in the Project upon completion of several exploration, engineering and development milestones over a five-year period. In exchange for its 60% interest, Ero will solely fund a phased work program during the earn-in period and grant VBM up to an 11.0% "free carry" on future Project construction capital expenditures. For additional details on the key terms and execution of the Agreement, please refer to the Company's press releases dated October 30, 2023 and July 22, 2024.
NOTES ON MINERAL RESOURCES
CIM Definition Standards (2014) were used for reporting mineral resources, which are effective as at June 30, 2024 and presented on a 100% ownership basis. All figures have been rounded to the relative accuracy of the estimates. Summed amounts may not add due to rounding. Mineral resources that are not mineral reserves do not have a demonstrated economic viability.
Mineral resource estimates are prepared by or under the supervision of and verified by Mr. Cid Gonçalves Monteiro Filho, SME RM (04317974), MAIG (No. 8444), FAusIMM (No. 329148). Mr. Monteiro is Resource Manager of the Company and is a “qualified person” within the meanings of NI 43-101.
Mineral resources have been estimated using a copper price of US$9,259/tonne, a gold price of US$1,900/oz, a USD:BRL foreign exchange rate of 5.10, and copper and gold metallurgical recovery rates of 85.00% and 61.50%, respectively. The estimation was constrained using Datamine's Mineable Shape Optimizer ("MSO") at a 0.55% break-even copper cut-off grade. Mineral resources were estimated using ordinary kriging within a 25-meter by 25-meter by 4- meter block size (X, Y, Z), with a minimum sub-block size of 6.25 meters by 6.25 meters by2.0 meters.

QUALITY ASSURANCE & QUALITY CONTROL
Four diamond exploration drilling campaigns were previously carried out on Furnas, with control sample protocols applied to each campaign. Historical QA/QC data was evaluated, including duplicates, blanks and standard samples from the most recent drilling campaign.
In all drilling campaigns, a quarter of the recovered core sample was collected. In the first three exploration campaigns, one-meter sampling intervals were predominately used. In the fourth exploration campaign one-meter sampling intervals were predominately used in the mineralized zone and two-meter sampling intervals were used in the transition zone and in waste rock.
Physical preparation of the quarter-core samples was performed in the following laboratories: Vale/Carajás, Intertek-Parauapebas-PA, Intertek-Nova Lima-MG, SGS GEOSOL, or Lakefield-Geosol. Chemical analysis was performed by ACME, Lakefield-Geosol in Belo Horizonte/MG, and SGS Geosol Laboratories in Vespasiano/MG. The selection of analytical methods and the number of elements analyzed varied across exploration campaigns.
To verify the accuracy of older sampling campaigns, a post-mortem QA/QC program was performed on copper and gold for select assay intervals. The post-mortem program undertaken by the Company demonstrates good performance, particularly for copper and gold, allowing for the inclusion of historical exploration campaign data for the purposes of this press release.
The Company reprocessed all historical QA/QC data from the Project, according to the Company's internal guidelines, and achieved exceptional results aligned with industry standards. Error rates for pulp and coarse duplicates remained significantly below the conventional limit of 10%, demonstrating the effectiveness of historical data preparation and analytical procedures. Global biases across all drilling phases and laboratories stayed well within acceptable parameters, confirming the analytical accuracy of the primary laboratories associated with the historical database. Additionally, the absence of significant contamination in all laboratories further validates the reliability and integrity of the reprocessed data.

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES
Unless otherwise indicated, all reserve and resource estimates included in this press release and the documents incorporated by reference herein have been prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this press release and the documents incorporated by reference herein use the terms “measured resources,” “indicated resources” and “inferred resources” as defined in accordance with NI 43-101 and the CIM Standards.
Further to recent amendments, mineral property disclosure requirements in the United States (the “U.S. Rules”) are governed by subpart 1300 of Regulation S-K of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) which differ from the CIM Standards. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the “MJDS”), Ero is not required to provide disclosure on its mineral properties under the U.S. Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If Ero ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then Ero will be subject to the U.S. Rules, which differ from the requirements of NI 43-101 and the CIM Standards.
Pursuant to the new U.S. Rules, the SEC recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the definitions of “proven mineral reserves” and “probable mineral reserves” under the U.S. Rules are now “substantially similar” to the corresponding standards under NI 43-101. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that Ero reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are “substantially similar” to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that Ero may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Ero prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.
